Lax rebounders. Top 5 Lacrosse Rebounders: Enhance Your Skills with the Best Bounce Back Walls in 2024

What are the best lacrosse rebounders for improving passing and catching skills. How do size, durability, and rebound affect your choice of a lacrosse bounce back wall. Which lacrosse rebounder offers the best value for money in 2024.

Understanding Lacrosse Rebounders: Your Personal Training Partner

Lacrosse rebounders, also known as bounce back walls, have become an essential training tool for players looking to improve their stick skills. These devices simulate the experience of passing and catching with a partner, allowing athletes to practice independently and consistently. By providing immediate feedback on throw accuracy and catch readiness, rebounders help players develop muscle memory and refine their techniques.

The importance of regular practice in lacrosse cannot be overstated. With a rebounder, players can work on their skills anytime, anywhere, without the need for a practice partner or a suitable wall. This accessibility makes it easier to maintain a consistent training regimen, which is crucial for skill development and performance improvement.

Key Benefits of Using a Lacrosse Rebounder

• Improved passing accuracy
• Enhanced catching skills
• Development of ambidexterity

Factors to Consider When Choosing a Lacrosse Rebounder

Selecting the right lacrosse rebounder can significantly impact your training effectiveness. Several factors should be taken into account to ensure you choose a rebounder that meets your specific needs and training goals.

Size Matters: Finding the Right Fit

The size of a lacrosse rebounder is a crucial consideration. Smaller models offer portability and ease of storage, making them ideal for players with limited space or those who need to move their equipment frequently. Larger rebounders, on the other hand, provide a more expansive surface area, which can be beneficial for improving accuracy and simulating a wider range of game scenarios.

Do larger rebounders always offer better training opportunities? Not necessarily. While a larger surface area can be advantageous, it’s essential to consider your available space and specific training needs. A well-designed smaller rebounder can still provide excellent practice opportunities if used correctly.

Durability: Ensuring Long-Term Value

The durability of a lacrosse rebounder is directly related to its construction materials and build quality. Metal rebounders are typically more durable and weather-resistant, making them suitable for outdoor use and long-term investment. Plastic rebounders, while often less expensive, can still offer good durability if well-constructed.

When assessing durability, consider factors such as:

• Frame material (metal vs. plastic)
• Mesh or netting quality
• Weather resistance
• Manufacturer warranty

Budget Considerations: Balancing Cost and Quality

Lacrosse rebounders come in a wide range of prices, typically ranging from $30 to $200 or more. While it’s tempting to opt for the least expensive option, it’s important to consider the long-term value and effectiveness of your investment.

How can you determine the best value for your budget? Consider these factors:

• Frequency of use
• Desired features (adjustability, size, portability)
• Long-term durability
• Brand reputation and customer reviews

Rebound Quality: Customizing Your Practice Experience

The rebound quality of a lacrosse rebounder can significantly impact your training effectiveness. Some rebounders offer high bounce-back, simulating faster-paced play, while others provide a more controlled return, which can be beneficial for beginners or specific drills.

Many high-quality rebounders feature adjustable tension, allowing players to customize the rebound to suit their skill level and training objectives. This adaptability can be particularly valuable as you progress in your lacrosse journey, ensuring that your rebounder remains an effective training tool as your skills improve.

5 Best Lacrosse Rebounders for Passing & Catching in 2023

Equipment

Written byLax Farmer Updated onJune 18, 2023

It’s no secret that lacrosse is a challenging sport. The best way to improve your skills and become a better player is to practice your stick skills as much as possible. The problem? We don’t always have a friend around to catch and throw with, or a brick wall to bounce off of.

That’s why it’s imperative to have a lacrosse rebounder. They help improve passing accuracy, catching, and most importantly – muscle memory. Practicing with a rebounder, along with the other best lacrosse training aids, helps make passing and catching (with both hands) become instinctual during game time. Let’s jump into our list for the best lacrosse rebounders on the market.

What to look for in a Rebounder (or Bounce Back)

Under pressure. The main mistakes in the selection and operation of balers
AGCO

How not to miscalculate the choice of a baler, how to set it up correctly and what mistakes should be avoided during operation, are told to the journal Agrotekhnika i Tekhnologii by experts from the manufacturers of this equipment: Rostselmash, CNH Industrial, AGKO-RM, Kun Vostok, John Deere, Kverneland, Krone Rus, Claas

Procurement, made during the short agronomic window allotted by nature, will feed livestock throughout the year. The quality of animal feeding, their productivity and the economic well-being of the enterprise depend on the correct choice and uninterrupted operation of the baler.

The choice of equipment such as a baler is primarily based on the volume to be harvested, the type of feed, the crop and harvesting time. For example, bale machines are beneficial to use by farms with large volumes of harvesting.

For balers that harvest rectangular bales, the density of pressing is higher than for roll bales, compares Krone Rus’ sales representative for the Siberian Federal District and the Far East Federal District Konstantin Taskin. The same can be said about productivity: round balers stop moving across the field while tying, while square balers work non-stop. What’s more, one large hay and straw baler can match the performance of seven PRF balers.

Experts believe that in terms of volumes, the purchase of large bale machines is beneficial for those who harvest more than 10 thousand packages per season, and for whom the required work productivity is more than 40 tons per hour.

According to Radik Garaev, product specialist at CNH Industrial (Case IH, New Holland Agriculture), large square balers will be the best purchase for those farms that harvest straw on an industrial scale (for sale or for their own needs) or work under a contract during harvest season.

In addition, unlike rolls, bales are more convenient to transport and store: a more ergonomic rectangular shape allows you to optimally use the storage area (put bales in several rows on top of each other).

Another argument in favor of choosing a large bale press is the reduction of mechanical losses up to 2-3 times (especially legumes) due to the greater preservation of nutritionally valuable leaves, argues Sergey Sozinov, product specialist, harvesting equipment, AGKO-RM company .

However, when choosing such a machine, it should be remembered that packing in bales implies a denser filling (the density of hay pressing in bale balers is 30-50% higher than in roll balers), respectively, it is necessary to more carefully monitor the moisture content of the pressed material and carry out the removal bales from the field before the onset of precipitation.

This means that those enterprises where climatic conditions do not allow harvesting hay with a moisture content of less than 15-16% will have to use additional equipment for adding preservatives to feed, says Sergei Sozinov. On the other hand, the penetration of external moisture in a large dense bale is much more difficult than in a bale, which ensures better preservation of the feed.

For farms harvesting wet mowed or slightly dried mass, roll machines are more suitable, where it is possible to form a package with a loose middle, which will allow the hay to “breathe”, that is, to dry out in the package, advises Roman, product manager for forage harvesting at CLAAS Fedotikov.

Specialist of Kun Vostok on the green line (Kuhn forage and animal feeding equipment) Mikhail Bazan recalls that bales are 30-40% heavier than bales of the same diameter, therefore, when purchasing a super-productive baler, you need to remember that bales, formed by such machines can weigh up to 800-900 kg. And therefore, the farm must have special vehicles (telescopic loaders, etc.) capable of loading such bales onto vehicles.

If the farm does not have loaders or self-loading carts for collecting rolls and bales from the field, then it is not advisable to buy a large baler, Rostselmash is sure. In such a situation, Prokhor Darmov, director of the Rostselmash marketing department, advises opting for small bale machines that produce packages weighing 25-30 kg, which can be easily carried by hand. And if you equip a small baler with an unloading device, you can immediately unload the received bales into the trailer.

Such machines are suitable for small farms with a livestock of 50-100 cows, or specialized farms that deal with horses, sheep, camels.

There is another interesting technology that involves pressing a group of small ones into one large bale. In this case, the length of small bales can vary from 0.30 to 1.35 m. This allows you to make traditionally large bales up to 3. 2 meters in size on the field and reduce transport costs for removal from the field, and on the farm to crush them into more small to facilitate physical labor when distributing feed.

Bale chamber selection

Most manufacturers divide models into classes (segments) by the volume of the workpiece, and, accordingly, by the life of the machine. Small volumes – easier equipment, thinner chains and sprockets. Larger volumes – more powerful units and structures are installed.

Ivan Bayak, a specialist in combines and forage harvesting equipment at John Deere, classifies round balers as follows: if the harvesting of an enterprise is up to 1 thousand rounds per season, then it is quite possible to get by with a machine with a basic configuration. If the farm needs to harvest 1-5 thousand bales per season, then more advanced machines of medium specification are needed, allowing the formation of bales up to 1.5 m in diameter with a fixed or variable pressing chamber.

As Roman Fedotikov from CLAAS explains, mid-range balers have mechanisms designed for longer operation (reinforced rollers, larger diameter chains, larger belts, etc.), as well as a set of options to reduce machine maintenance time and facilitating the work of the mechanic.

CNH Industrial specialist Radik Garayev believes that the optimal size of rolls should be 1.20 x 1.25 m. This, according to him, is due to the convenience of transporting such blanks. Two rolls 1.20×1.25 m wide will amount to 2.5 meters, which is the permitted overall width on unaccompanied public roads.

Do not forget that the choice of a roll press with a certain type of press chamber is closely related to the crop to be harvested and the moisture content of the feed. In general, such machines are produced with a fixed (constant) or variable (variable) chamber.

Constant chamber

A fixed (constant) chamber forms bales of the same size, it is easier to maintain and repair and is cheaper than variable machines.

Fixed chamber balers, in turn, are also divided into several types. For example, there are machines with chain-and-slat pressing mechanism that work very well on dry matter, says Alexey Letyagin, head of sales at Kverneland. According to him, the bar ideally picks up dry material (straw, hay) and rolls it into a roll, however, on wet material (haylage, silage), the pressure of the bar is not enough to tightly crush the mass and prevent oxygen from entering the package. Due to the fact that the bar on such material is bent, the chains are stretched, the machine quickly breaks down, and the forage is of poor quality, the expert states.

It is absolutely inexpedient to use such machines when harvesting legumes with delicate foliage (for example, alfalfa, etc.) for hay, since chain-slat cameras severely injure the mass, knocking down valuable foliage, Mikhail Bazan warns. And if you miss the deadlines for harvesting, then only stems will fall on the fodder table for cows. Therefore, this type of camera (one of the most common today) is good for working with straw and hay from cereals.

On the contrary, rolls with a roller compaction chamber (rolls are involved in the formation of the roll) have proven themselves well when working with wet mass, Alexey Letyagin continues. They are suitable for silage harvesting, having a decent compaction density. But at the same time, they do not work well with dry mass, since, due to their design features, they have the effect of “knocking down” a lightweight substance, and not twisting it into a roll. Because of this, the roll often turns out to be crooked or loosely packed, Letyagin notes.

Thus, if the harvesting of bales with heavy haylage or silage with a moisture content of 40-60% prevails on the farm, a roller chamber that is resistant to such loads will be a good choice, Ivan Bayak has no doubts.

The combined bale chamber in round balers is a combination of two mechanisms: chains with slats and rollers (or belts) with rolling pins. This is the most versatile option, Letyagin believes: the main pressing load is on the rollers, while picking up and twisting the mass takes place in a small section of the bar. As a result, the machine performs well with both dry and wet stock.

For farms growing legumes, Roman Fedotikov recommends cameras with straps. They can be either constant or variable. Such chambers have a large roll overlap area, and when working with them, there is less loss. They do not knock down leaves as much, carefully preserving the nutritional value of legumes.

The belt press chamber makes it possible to form dense bales from the beginning to the end of the process, which is also suitable for harvesting haylage, says Prokhor Darmov, director of the Rostselmash marketing department.

By the way, when working in arid areas and when harvesting straw, the machine has to be constantly cleaned (blown) from clogging dust and straw chaff in order to avoid fire, Aleksey Letyagin warns.

Variable geometry

Unlike a fixed chamber, a variable or variable bale chamber makes it possible to form bales of various diameters (from 1.2 to 2.1 m), which can be useful for packaging different types of feed (straw one size, hay another, etc.) .), if required by storage or transportation conditions. In addition, according to Letyagin, such chambers are good for harvesting haylage: pressing starts from the very middle, and the bale density will be maximum.

However, Ivan Bayak advises purchasing a chamber with variable pressing geometry for those who harvest haylage with a moisture content of no more than 40%. The reason is that on a heavy wet mass, the belts can experience significant stress, the specialist explains.

According to Ivan Bayak, on some models it is possible to press with different pressures: first 50 bar to get, for example, a bale with a soft center, and at later stages of bale formation, increase the pressing pressure to 200 bar. Thus, the core of the roll has the ability to “breathe”, but at the same time the outer part of the roll will be dense and more moisture resistant.

There is another type of variable chamber – semi-changeable. The basis of this chamber is a fixed, expandable slat chamber. The mass is first pressed in a fixed chamber with a diameter of 1.2 m, and after the roll is pressed, it expands to a predetermined diameter, Letyagin says. Such machines, in his opinion, should be chosen by those for whom straw is the predominant product of harvesting: the packing density is combined with the absence of the need for constant blowing of the belts.

Prokhor Darmov from Rostselmash also advises not to forget that to get haylage you need a baler with a chopping machine. For hay, this function is not required.

Feeder selection

When choosing a baler, Ivan Bayak advises to pay attention to the feeder: it is located between the stock pick-up and the baling chamber and has the task of actively feeding the mass into the chamber. Such nodes are finger and rotary.

On simple balers, making up to 1 thousand bales per season, finger feeders are installed. But if the productivity of the machine is higher, there is a need for a more active feed, explains Ivan Bayak. The tine feeder is better suited for light swaths of bean hay (alfalfa, clover, etc.) as it handles the stock more gently. And where the humidity is higher (25-40%), it is more efficient to use a rotary feeder with a mass grinding system, which will provide higher productivity and pressing density.

Rotary feeders with a grinding system can be used on machines with chambers with both fixed and variable geometry.

Tractor selection

Even at the stage of choosing a baler, you need to think about the aggregation of this machine.

Farmers, when choosing a pick-up, are often guided by the value of the total power of the tractor or on the PTO, while when driving on a flat surface, the tractor requires at least 14-15 hp. for traction. And when moving along an inclined path, about 20-25 hp are needed for these purposes. Accordingly, if according to the instructions for the operation of the baler, a tractor with a power of 82 hp is required, then MTZ 82 will not be enough. When moving, its power is not enough to operate the press, moreover, if the unit is equipped with mass grinders, it must be taken into account that this will further increase energy consumption.

You need to be especially careful when choosing a tractor for large-pack heavy presses, for which the power reserve should be from 130 hp. for models 80-90 up to 200 hp for models 120-90 hp, Konstantin Taskin from Krone Rus pays attention.

But at the same time, one should not greatly exaggerate the power of the tractor, otherwise it will not “feel” the unit, Mikhail Bazan warns. A tractor two classes more powerful than required will drag the unit over the swath at high speed, resulting in crooked and poorly formed bales.

Net or twine?

The type of binding of the final roll is important for further storage and transportation of blanks. There are three options for packaging the harvested feed: tying with twine, netting or wrapping in film.

Twine wrapping is cheaper. But the main thing is that the cost of rolls wrapped in this way is 30-40% lower than rolls wrapped with mesh. However, net packing is faster and of higher quality. According to Rostselmash calculations, it takes only 1.5-2 turns and 5 seconds to wrap a standard roll with a diameter of 1.2 m into a net. Whereas in order to wrap the roll with twine, 8-10 turns of the thread are needed, which takes an average of about 1 minute.

With a double-filament wrapper, the process can be reduced to 20-25 seconds, but even this indicator is inferior in speed to net wrapping.

Many farms, in an effort to save money, use domestic twine and netting, which reduces the cost of producing one roll by about 20% compared to imported polymer analogues.

Sergey Sozinov from AGKO-RM notes that large square balers place high demands on the strength of the twine – the breaking force must be at least 200 kg per knot. Don’t skimp too much on twine, this can lead to reduced productivity through more downtime due to troubleshooting. In addition, when the finished bale is tilted, poor-quality twine can break, which will make the bale more loose, vulnerable to moisture and less convenient for transportation and storage.

In addition, with such replacements for analogues, it is necessary to monitor the condition of the knotter elements, since some Russian twine analogues contain too rigid materials and can disable knotting equipment, Konstantin Taskin warns. For example, the guide wheels of the distribution mechanism of knotters sometimes fray, breaking in half, in just a year of using Russian twine, and not only on Western European presses, the specialist notes. According to his observations, such a problem also happens in the Belarusian PRF.

On domestic polymers

Experts recommend carefully studying and comparing the characteristics of polymers when using analogues. Everything should be the same: tensile strength, texture, tension density and the thickness of the thread itself. However, according to Roman Fedotikov, the true quality of twine can only be verified empirically.

When replacing the net, Ivan Bayak advises, in addition to the characteristics specified in its specification (the width of the net must correspond to the width recommended by the baler manufacturer, the strength characteristics must correspond to the original net), to evaluate its oiliness. If the mesh contains a lot of oil (when compressed, it remains on the hands in a large amount), then it will slip on the feed rollers of the packaging system, which will lead to poor packaging quality (insufficient number of mesh turns). In addition, it is worth paying attention to the thickness of the threads, their pitch. They should also be as close as possible to the grid values ​​that the manufacturer recommended for use on the machine.

At the same time, Ivan Bayak notes that a mesh with a diagonal weave between the main threads is stronger and better fits the roll, and if there are elastic threads along the mesh cut in the sidewalls (for example, CoverEdge ^tm ), then such a mesh holds and closes the edge of the roll very well.

For those who often change polymer manufacturers (both net and twine), Mikhail Bazan advises to control the position of the bale pretensioner. At the factory, the tension in this node is set to base values, but when changing polymers, its position must be changed and adjusted to the new values ​​experimentally, he says. For example, if the top layer of the mesh comes off in a roll, it means that the pretensioner is not properly tensioned, and if the mesh burst during unloading, it means that it was overtightened, explains Bazan.

When wrapping in film, experts advise remembering that a roll falling from a great height, especially on sharp stubble, can cancel out all the work on haylage harvesting – the film will break through, the feed will be spoiled. Therefore, when choosing a pick-up with the function of simultaneous film wrapping, it is advisable to order a rubber ramp complete with the machine – walkways along which the bale can gently roll onto the field without the risk of being pierced.

And it is even better to purchase the option of “reversing” rolls, experts advise. In this case, the roll stands on the end and a breakthrough is practically impossible, since at the ends of the roll there are several times more layers of wrapping with a film.

When packing with a film, from 4 to 10 layers are wound. In addition, the gripping of such rolls during loading must be carried out by special equipment with soft edges. It is desirable to store such rolls in a vertical position.

Balers | IRON-HORSE.RF

K The form is compacted in three ways – by pressing, briquetting and granulating. Pressing implies compaction of roughage with their further formation into cylindrical rolls or rectangular blocks (density up to 300 kg/m ³ ). Pressing density is divided into three types:

1) low – up to 100 kg/m ³ ;

2) medium – 100-200 100 kg/m ³ ;

3) high – 200-300 100 kg/m ³ .

D For areas of desert and steppe zones, a low density of straw and hay pressing is recommended, while pressing the mass, whose moisture content reaches 40%, is permissible, with further drying through active ventilation.

In desert and steppe zones, as well as in the central regions of the forest-meadow zone, an average compaction density is used. When pressing, the permissible humidity is 25%.

In desert and desert-steppe zones with a moisture content of the mass reaching 22%, a high pressing density is recommended. The high density of pressing makes it possible to transport bales over long distances.

Briquetting implies compaction (within 500-900 kg/m ³ ) cutting straw or grass, feed mixtures consisting of roughage particles (20-70 mm), into cylindrical blocks (diameter 20-65 mm) or other shapes (maximum size – 80 mm).

Granulation means compaction (up to 900-1300 kg/m3 ³ ) of floured feed mixtures or components. The form of production of granules can be cylindrical (maximum diameter – 20 mm) or curly. When granulating, the optimum moisture content is 14-16%.

balers include:

1) – picking up plants from swaths;

2) – devices for preliminary mass compaction;

3) – fillers (loaders) of compacted portions into the pressing chamber;

4) – pressing devices;

5) wrapping or knitting machines;

6) – drive mechanisms of working bodies;

7) – process control mechanisms.

P balers are divided according to the shape of the compressed mass and the principle of operation into roll and piston.

The round balers roll straw and hay in balers (fixed or variable section) into cylindrical bales.

The fixed chamber balers are available as conveyor and roller balers.

H a [fig. 1] shows a diagram of a PR-F-750 round baler with a chain-roller conveyor. The drum pick-up (1) with spring tines picks up crop material from the swath. The mass is fed to the pressure grate (2) and then to the feed rollers (3) and (6). As soon as the chamber (5) is filled, the mass is put into rotation by means of the rollers (3) and (6) and the conveyor (4).

2) – Pressure grid;

3) – Rollers;

4) – Chain and roller conveyor;

5) – Camera;

6) – Rollers.

Starting from , the chamber space is filled. Further, with an increase in the compression force, the roll is compacted (especially the outer layers), while its central part remains less compacted. As soon as the density reaches the required value, the roller (3) will turn on the signal device and the bale will begin to be wrapped with twine. At the end of the winding, the rear wall with a chain-roller contour rotates relative to the hinge (O) and the roll is unloaded onto the field by means of rollers (6).

The designs of imported balers use chambers of constant section, which form steel rollers or a series of conveyors placed around the periphery of the chamber.

B Timeless balers are distinguished by their simple design and reliability.

D Roll presses are used for low as well as medium densities. The safety of leaves in rolls is higher, as they are wrapped inside. Compared to piston balers, round balers are less energy intensive. The high density of bales in the peripheral zones and the low density in the middle increase the rate of final drying of plants in the field, as well as the safety of hay without shelter.

P baler PR-F-750 forms rolls with the following parameters: diameter – 1.8 m, length – 1.5 m, density – 100-200 kg/m ³ , weight – up to 750 kg . This baler is aggregated with tractors 1.4 and 2 of traction class. Energy consumption for the operation of the baler is 1.7-2 MJ / t, throughput is 7. 5 kg / s.

O Bale wrapping with twine only starts when the bale has reached the set density, after a signal has been given. The machine operator stops the unit and turns on the winding machine. The hanging end of the twine is captured by the incoming plant mass – the winding of the rotating bale begins.

P By setting different twine feed modes, the number of turns of twine per bale changes. After completing the winding, cut the twine with a knife. The change in twine tension is carried out by a brake.

M The operator, having cut the twine, opens the rear wall of the bale chamber by means of a hydraulic cylinder, the lower rollers (6) unload the bale onto the ground. Then the work cycle is repeated. Twine consumption for wrapping a ton of feed compressed into a roll is 0.5 kg.

Variable chamber balers collect bales between belts (6) and (10) [fig. 2]. During the movement of the unit, the fingers of the pick-up (1) lift the mass from the swath and transfer it to the belt conveyor (10). Between this conveyor and the drum (11) the layer of plants is compacted and then it is twisted (loop area A) by means of pressing belts (6) and (10).

During the roll formation, the size of the loop increases (by turning the frame (3) clockwise). The resistance to frame rotation depends on the compression force of the spring (5), as well as the resistance of the oil that is pushed out of the cavity (I) of the hydraulic cylinder (16) into the pneumatic accumulator (2). The pressing density depends on this resistance. Density adjustment is carried out by a spring (14), which compresses the check valve (13). The control is carried out on the manometer (12). The maximum pressure should be no more than 5 MPa.

P When the roll reaches a predetermined diameter, an apparatus starts to work, which wraps the mass with twine (several turns). Wrapping should be carried out with the machine stopped. The bale is ejected by the pressing belts when the frame stop (3) opens the connection of the latch (8) with the valve (7), which, under the action of a compressed spring (5), rotates about the axis (O) and releases the formed bale to the ground.

P The frame returns to its original position by means of a hydraulic cylinder rod, moved under the influence of oil, which is supplied to the hydraulic cylinder from a pneumatic hydraulic accumulator. If required, you can turn the valve (7) and supply oil from the tractor hydraulic system via line (20). In this case, the oil overcomes the resistance of the spring (18) of the shutter and moves the piston (19), entering the cavity (II) of the hydraulic cylinder (16). If the tractor’s hydraulic system is not used, then the spool of its hydraulic distributor should be set to the “floating” position. In this case, the spring (18) moves the valve piston (19) to the left position, as a result of which the cavity (II) of the hydraulic cylinder (16) communicates with the atmosphere through the breather (17), which helps to reduce the resistance of the stem to movement during the valve lowering.

P When pressing wet grass (up to 45%), balers are equipped with devices that allow dosed introduction of chemical preservatives, which reduce the loss of nutrients during long-term storage of feed (up to six months).

P baler PRP-1.6 has the following parameters of formed bales: density – 100-200 kg/m ³ , diameter – 1.5 m, length – 1.4 m, weight – up to 500 kg . This baler is aggregated with tractors 1.4 traction class. The energy consumption for the operation of the baler is 4.0-4.5 MJ / t, the throughput is 7.5 kg / s, the speed is up to 9 km / h. When picking up and pressing, losses reach 2%.

The piston balers are used to compress plant matter into small and large bales weighing up to 35 and up to 750 kg respectively.

The small balers compress the mass (without pre-compaction) in a special chamber. During the movement of the unit [Fig. 3] with the fingers of the drum pick-up (3), the plant mass is fed from the swath to the filler (3). The filler pushes the mass through the tines into the pressing chamber (B), which is formed by the press body, the end face of the piston (4) and the previous pressed mass. The piston during this period makes an idle stroke.

8) – Density regulator.

P the piston captures a portion of the mass with each stroke and moves it along the chamber. From the clamp (2), through the chamber, along the guide rollers of the needle (7) to the cassette (6), the twine passes. The compressed mass, moved by the piston, pulls the twine out of the cassette. The twine goes around the bale, as it grows, from three sides. The teeth of the measuring wheel (1) engage with the ground. When the mass moves, the wheel turns, and after each revolution it turns on the clutch, which is responsible for driving all parts of the knitting machine. The needles begin to move, passing through the slots of the press chamber, as well as the grooves of the piston. The bale is covered with twine in one or two planes (from the side of the piston). Through the slots located in the cover of the chamber, the needles go out, the second branch of the twine is placed in the clamp of the knotters, where both ends of the twine are tied into a knot. This completes the formation of the bale and its binding. Next, the piston starts pressing the next bales, methodically pushing the bound bales out of the chamber, which, when leaving the latter, enter the trays, where they are separated at the place of the bundle. The bales leave the trays or onto the field or in the containers of vehicles passing by.

P parameters of bales formed by the PPL-1.6 baler (side feed of mass into the pressing chamber): length – 0.5-1 m, width – 0.5 m, height – 0.36 m, density pressing – 100-200 kg/m ³ . The capacity of the baler is 8 kg/s, the working width is 1.6 m. This baler is aggregated with tractors of 1.4 traction class, the speed is up to 9 km/h. Bale stacking is carried out not only on the field, but also in the container of a nearby conveyor. The number of loose bales and the allowable crop loss must not exceed 2%.

The Big Balers compress straw and hay into bales weighing up to 750 kg. Immediately before pressing, the plant mass is pre-compacted in the chamber. In these machines, the pick-up is located not on the side, but frontally (symmetrically to the longitudinal plane).

During the operation of the machine [Fig. 4] the drum pick-up fingers (1) pick up the swath. The flow is narrowed from the periphery by means of the left and right cantilever augers (2) towards the loading window of the storage chamber (A), the beater-filler (3) pushes the mass into the chamber. The fork loader arm (4) is out of the chamber. When the density of the mass in the chamber (B) increases to the required value, the levers (4) turn, the fork loader automatically turns on. The compacted mass is fed in portions into the pressing chamber, while the piston (5) occupies the extreme right position. During the filling of the chamber volume, the valve (7) is rotated, and at a given force, the piston drive mechanism (6) is activated, compressing the mass. At the same time, the knives cut off the tails of the plants. When the bale reaches a predetermined length, the measuring wheel (8) turns on the knitting machine, which binds the compressed bale with twine (in 4-6 planes).

P The degree of pre-compression is adjusted by changing the tension of the valve springs. The degree of final pressing is adjusted by bringing the sealing strips (9) closer together.

When pressing wet mass, the sealing strips must be brought closer together than when pressing dry mass. Automatic density controllers are also used. These balers (bottom front feed into the bale chamber) are more compact than side feed balers. Pre-compaction not only reduces energy consumption for pressing, but also for further work on the selection, loading and transportation of bales.

P parameters of bales formed by the PKT-F-2 large bale baler: length – 1.2-2.4 m, width – 1.1 m, height – 1.2 m, pressing density – 150 kg / m ³ , weight – up to 500 kg. The capacity of the baler is 10 kg/s, the working width is 2 m. This baler is aggregated with tractors of 1,4 and 2 traction class, the speed is up to 12 km/h. The bale is tied with twine in five planes. The number of untied bales – up to 3%, forage loss during harvesting – up to 1.5%.

Knitting machines. Bales of flax, straw, hay are tied around knitting devices, which include: a needle; clip; beak; knife; drive mechanisms.

Needle has the form of an arcuate rod with a channel (1) [fig. 5] and a pair of holes (2) for twine. She receives the drive from the lever mechanism.

Clamps are available in two types: disc and disc. The composition of the disc clamp system “Mc-Cormick” includes: a fixed plate (4) with a slot (5) and a disk (3) rotating in it, which has a number of recesses and protrusions. The hook (6) presses the plate against the disc. The needle places the twine in the slot (5) of the plate and as the disc rotates, the twine is clamped between the disc and the plate. Most flax harvesters and balers use a disc clamp.

D Claim clamp (Dühring system) is made in the form of a pair of rotating discs (9) with six cutouts. Between the discs there is a bracket (10) and a twine holder (8). Getting into the cutouts, the twine is pressed against the holder during the rotation of the disks. The flat spring (7) that holds the holder between the discs is used to change the tightening force of the twine.

The beak (D) of the twine knitting device consists of a fixed (13) and a movable (12) jaws, the latter is hinged on the axis (14). The roller (11) is mounted on the shank of the moving part, it rolls along the treadmill of the lever, closing or opening the jaws. The spring that presses the track against the roller is used to change the degree of clamping in the jaws of the twine beak.

Knife (15) in machines equipped with a plate clamp is made fixed. The knife and the rotating clamp disc form a cutting pair that cuts the twine.

Drive mechanisms of the knitting machine receive the driving moment from the PTO (power take-off shaft) of the tractor through the gearbox, as well as the cardan, chain, lever transmissions.

M The knotter mechanisms are driven periodically (after 1 revolution of the measuring wheel (1)) [fig. 3]. The teeth of the wheel are included in the pressed mass, and in the process of pushing the next portion, the wheel is rotated at a certain angle. The engagement lever is rotated by the disks of the wheel shaft, thereby releasing the two-arm lever. At the same time, its stop, having disengaged from the engagement lever, releases the pawl with the roller, which in turn comes into contact with the cellular drive clutch. From the clutch, the torque is transmitted through the pawls to the knotter.

P At the end of the cycle of the knitting machine, the activation lever returns to its original position. In this case, the pawl comes into contact with him and is separated from the shaft of the knitting machine, while the clutch does not stop rotating freely.

Knotter workflow (workflow of knotter elements).

Fig. 6. The process of linking the node.

I-V – Positions of knotter elements.

Item I [fig. 6] – the needle is outside the chamber, it is motionless, the twine from the spool, the channels and holes of the needle pass into the chamber, encircling the bale from three sides, clamped between the clamp disk and the plate.

Position II – stroke of the needle. The needle covers the bale with twine, lays its upper branch on the jaw of the beak, and also brings the second end of the twine to the clamp.

Position III – the end of the needle stroke. The beak and clamp come into action. The second strand of twine is caught by the rotating clamp disc and clamped. The beak turns, while the twine covers its jaws and they open slightly. The latter is dropped from the stop.

Position IV – needle movement in the opposite direction. The disk, capturing both branches of the twine, continues its rotation (the branches of the twine are fed into the open throat of the beak).

Position V – continuation of the movement of the needle to its original position. Full turn of the beak and stop. When closing the jaw, the twine is pinched. One strand of twine is cut with a knife. The loop is removed from the beak by bales pushed by a piston, while the pinched strands of twine are pulled through and form a knot.

D The diameter of the twine used for tying bales is 1.8-3 mm. When tying flax bales, the minimum breaking force must be 250 N.

Knot ties . The quality of forage harvesting and the performance of balers are characterized by the reliability of the knitting machine. A maximum of 3% loose bales is allowed.

H knot ties are directly dependent on the adjustment of the knotter mechanisms, the twine thread guide, and the knitting machine drive.

Table 1. Causes of node miscommunication and ways to eliminate them.

In with the above causes, bale binding failure occurs due to the blunting of the knife blade.
