The utility model relates to agriculture, in particular, to fodder production.

Known round baler consisting of a pressing chamber with chain conveyors, a selection mechanism, a clamping lattice, augers, narrowing rolls, a wrapping apparatus. (Round baler PPR-150. Operation manual [Electronic resource] / official website of Clover LLC. - URL: http://www.KleverLtd.com)

When selecting a hay roll, the mass is fed unevenly along the working width, because the roll initially has a cross section in the form of an isosceles trapezoid, then in the process of subsequent selection and pressing in the middle part of the roll, the highest pressing density is observed, and the smallest along the edges. The screws installed along the edges of the pick-up do not provide the necessary uniformity across the width of the roll.

The closest in technical essence is a round baler containing a pressing device made in the form of two support rollers and a chain-belt conveyor thrown over the drive and driven shafts, a pressing chamber, a pick-up, a stacker and a strapping apparatus, a drive shaft of the chain-belt conveyor is connected with support rollers with a chain drive, which reduces the peripheral speed of the rollers compared to the peripheral speed of the conveyor, the rollers, in turn, are equipped with ribs located on the outer rails surfaces with equal intervals, moreover, the number of ribs on the front roller is twice as many as on the rear roller, and their height is correspondingly smaller, while the stacker is equipped with a hinged shock absorber rod connected to the rake lever pivotally mounted on the crankshaft. (RF patent No. 2263440, IPC A01F 15/07, application of December 30, 2003, published November 10, 2005)

The well-known round baler works in conjunction with a tractor. When the unit moves along the roll and the press mechanisms are rotated by cardan transmission, the pick-up picks up the roll and feeds it into the space between the clamping grill, making preliminary compaction, then the stacker grabs, compresses the stem mass and pushes it through the inlet window into the press chamber. Under the action of rotation of the chain-slat conveyor and support rollers, the stem mass coming in with an endless ribbon is twisted into a roll, flattened and pressed. When the roll reaches a predetermined density, the pressure in the hydraulic system increases and the signal for starting the twine tying is turned on. The strapping apparatus feeds the twine with a hydraulic motor until it is caught by the roll, then the twine is wound onto the roll in a helix with a leash reciprocating when the strapping of the roll is finished, the twine is pressed against the knife and cut, at the same time the back of the bale chamber and the roll are opened under the action rotating rollers and rolls on a spring-loaded platform to the ground. After rolling out the roll, the back of the press chamber returns to its original position and the process is repeated in the same sequence.

A disadvantage of the known round baler is that in the process of selecting a hay roll, the shape of the roll practically does not change, and only it is compacted using a pressure grate. With the further formation of the roll, the uneven distribution of hay over the width of the roll is aggravated by twisting the roll into a roll. The uneven distribution of hay over the width of the roll leads to a decrease in the safety of the edges of the roll as a result of insufficient compaction density.

The problem the technical solution is aimed at is to increase the uniformity of the density of pressing over the entire volume of the roll.

The technical solution lies in the fact that increasing the uniformity of the density of hay pressing in rolls is achieved by leveling the hay roll with the same thickness over the entire width of the pickup.

The technical solution is achieved by the fact that in a round baler containing a pressing device made in the form of two support rollers and a chain-slat conveyor, thrown over the drive and driven shafts, a press chamber, a pick-up, a stacker and a strapping apparatus, a chain-slat drive shaft the conveyor is connected to the support rollers by a chain drive, the rollers, in turn, are equipped with ribs located on the outer surfaces at equal intervals, and the pick-up is equipped with a disk leveling device, mounted above the pick-up pick-up drum, the leveling device is made in the form of two disks with fingers fixed on a pivotally mounted frame and is installed with the possibility of changing the gap between the pick-up pick-up drum and disc fingers.

Comparative analysis with the prototype shows that the claimed device for making preservative preparations in the plant mass meets the requirements of "Significant differences".

1. The pick-up is equipped with a disk leveling device mounted above the pick-up pick-up drum.

2. The leveling device is made in the form of two disks with fingers fixed on a pivotally mounted frame

3. The disk leveling device is installed with the possibility of changing the gap between the pick-up pick-up drum and the fingers of the disks.

In order to regulate the uniform distribution of the hay roll along the pick-up width, the leveling device is made in the form of two disks with inclined fingers rotating in opposite directions. Hay roll raised by the pickup enters the gap between the pickup fingers and the inclined fingers of the rotating discs. As a result of the rotation of the disks of the screeding device, hay is pulled apart along the pick-up width and compressed due to different speeds of hay and inclined fingers.

In order to ensure the necessary degree of compaction of the hay roll, before pressing, the size of the gap is selected based on the average value of the weight per meter of the hay roll and the necessary density of pressing.

In order to improve the safety of pressed hay, uniform pressing is ensured over the entire width of the roll. Under the influence of rotation of the chain-slat conveyor, disk leveling device and support rollers, the stem mass is evenly distributed along the working width and along the movement of the roll, twisted into a roll, flattened and pressed. This allows you to ensure the same pressing density across the width of the roll, contributes to the descent of atmospheric moisture from the roll, and also limit the access of air.

The proposed device is illustrated by schemes, where:

in FIG. 1 shows a proposed round baler;

in FIG. 2 - kinematic diagram;

in FIG. 3 is a view A of FIG. 2, leveling device, top view.

The round baler consists of a grommet 1, a cardan gear 2, a hydraulic system 3, a wheel drive 4, a pick-up 5, a front part of a pressing chamber 6 and a rear part 7 pivotally connected thereto, a strapping apparatus 8, a horizontal disk leveling device 9, a pressing device consisting of support rollers: front 10 and rear 11, chain-slat conveyor 12, drive shaft 13 and driven shaft 14.

The drive shaft 13 of the chain-slat conveyor 12 is connected by a belt drive to the disks of the leveling device 9, in turn, the disks are connected by a belt drive in the form of a figure 8. 15. The disks are mounted on an arm 16 with an adjustment device for the height of the disk 17. The support rollers 10 and 11 are driven by a drive shaft.

In the working position, the pick-up 5 is lowered, the ends of its teeth do not touch the ground, the back of the pressing chamber 7 is closed and fixed by the hydraulic cylinders 18.

The round baler works as follows: when the unit moves along the roll and the press mechanisms are rotated by the cardan drive 2, the pick-up 5 picks up the roll and feeds it into the space between the disk leveling device 9 and the top of the pick-up. The disk leveling device pulls the hay along the pick-up width and compacts it due to the different speeds of the hay and inclined fingers, under the action of rotation of the chain-slat conveyor 12, the disk leveling device 9 and the support rollers 10 and 11, the stem mass is evenly distributed along the width of the pick and along the roll , twisted into a roll, flattened and pressed.

When the roll reaches a predetermined density, the pressure in the hydraulic system 3 increases and the signal for starting the twine tying is turned on.

The strapping apparatus 8 feeds the twine with a hydraulic motor 19 until it is caught by the roll, then the twine is wound onto the roll in a helix using a leash 20, which makes a reciprocating movement, when the strapping of the roll is finished, the twine is pressed against the knife 21 and cut, the back of the press chamber is simultaneously opened 7 and the roll under the action of the rotating rollers 10 and 11 rolls along the spring-loaded platform 22 to the ground. After rolling out the roll, the back of the pressing chamber 7 returns to its original position and the process is repeated in the same sequence.

The use of this round baler allows you to ensure the same density of pressing on the volume of the roll, promotes the descent of atmospheric moisture from the roll, restricts air access, which increases the safety of hay.
