Description

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

Known round baler, consisting of a bale chamber with chain conveyors, a pick-up mechanism, a clamping grid, augers, a narrowing roll and a wrapping apparatus. (Round baler PPR-150. Operation manual [Electronic resource] / official website of the Klever LLC company. - URL: http://www.KleverLtd.com).

When picking up a hay swath, the mass is fed unevenly across the working width. Since the roll initially has a cross-section in the form of an isosceles trapezoid, then in the process of subsequent picking and pressing in the middle part of the roll, the highest pressing density is observed, and at the edges the lowest. Augers installed over the edges of the pick-up do not provide the required edge compaction.

The closest in technical essence is a round baler (RF patent for utility model No. 157147 "Round baler", application No. 2015121102 dated 02.06.2015, issue date 20.11.2015 Bull. No. 32), containing a pressing device made in in the form of two support rollers and a chain-slat conveyor thrown over the drive and driven shafts, a bale chamber, a pick-up, a stacker and a strapping apparatus, and the drive shaft of the chain-slat conveyor is connected to the support rollers by a chain transmission, the rollers, in turn, are equipped with ribs located on outer surfaces with equal intervals, the pick-up is equipped with a disc leveling device installed above the pick-up drum of the pick-up, and the leveling device is made in the form of two discs with fingers fixed on a hinged frame, and is installed with the ability to change the gap between the pick-up drum of the pick-up and the disc fingers.

The disadvantage of the known round baler is that the installed leveling device, made in the form of two discs with fingers, does not provide high-quality compaction of the incoming stem mass at the edges, which leads to insufficient pressing density at the edges.

The problem to be solved by the technical solution is to increase the uniformity of pressing over the entire volume of the roll.

The technical result consists in increasing the uniformity of distribution of hay in bales.

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 bale chamber, a pick-up, a stacker and a tying device, the drive shaft of a chain-slat The conveyor is connected to the support rollers by a chain transmission, the rollers, in turn, are equipped with ribs located on the outer surfaces with equal intervals and a leveling device for the pick-up, and the leveling device is made in the form of two vertical driven rolls equipped with fingers and located on both sides of the pick-up.

Comparative analysis with the prototype shows that the claimed device for introducing preservatives into the plant mass meets the requirements of "Significant differences":

the pick-up is equipped with a leveling device made in the form of two vertical driven rollers, which makes it possible to form a swath coming to the pick-up;

the driven rollers are equipped with pins, which improves the uniformity of the roll entry;

drive rollers are located on both sides of the pick-up, which allows for pre-compaction of the swath to increase its uniformity.

The proposed device is illustrated by diagrams:

in fig. 1 shows the proposed round baler;

in fig. 2 shows a kinematic diagram.

The round baler consists of a frame 1, a cardan drive 2, a hydraulic system 3, a wheel travel 4, a pick-up 5, a front part of the bale chamber 6 and an articulated leveling device 9, a pressing device consisting of support rollers 11, a chain-slat conveyor 12, driving 13 and driven 14 shafts. The drive shaft 13 of the chain-slat conveyor 12 is connected by a belt drive with the drive rollers 15 of the leveling device 9, the rollers are fixed on the bracket 16. The rollers 11 are driven by the drive shaft.

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

The round baler works as follows: when the unit moves along the roll and the press mechanisms rotate by cardan transmission 2, the roll passes between the vertical drive rollers 9, equipped with fingers 10, and is fed into the pick-up. The leveling device compacts the sides of the swath due to the different speeds of the hay. Under the action of the rotation of the chain-slat conveyor 12, the leveling device 9 and the rollers 11, the stalk mass is evenly distributed over the working width and along the movement of the roll, twisted into a roll and pressed.

When the bale reaches the set density, the pressure in the hydraulic system 3 rises and the signal for starting twine tying is turned on.

The tying device 8 feeds the twine by the hydraulic motor 17 until it is captured by the bale, then the twine is wound on the bale along a helical line using a leash 18, which reciprocates, when the bale wrapping is finished, the twine is pressed against the knife 19 and cut off, at the same time the rear part of the bale chamber is opened 7 and the bale, under the action of the rotating rollers 11, rolls along the spring-loaded platform 20 onto the ground. After the roll has been rolled out, the rear of the bale chamber 7 returns to its original position and the process is repeated in the same sequence.

The use of this round baler allows to increase the uniformity of pressing over the volume of the bale and excludes slipping of the twine from the edges of the bale.
