Description

FIELD OF THE INVENTION

The invention relates to the field of agricultural engineering, can be used in devices for harvesting crops with a tow on the vine.

State of the art

A device for combing grain on the root, comprising a header mounted on an inclined chamber of a combine harvester, comprising a housing, a conveyor, a screw, a rotor, on which rows of combing fingers are rigidly fixed, wherein the rotor has additionally movable rows of combing fingers mounted parallel to the rows of main combing fingers fingers, while the moving rows of stripping fingers are made in the form of straight rods having rollers at the ends, and the cheeks of the stripping rotor drum have arcuate protrusions on both sides ( nt of the Russian Federation No. 2299551, class A01D 41/08, 2005).

The disadvantage is the increased level of free grain loss from knocking it out of the spike and the direction forward from the header by the rotor combs, rotating in the opposite direction to the harvester.

A cleaning device is known that comprises a copying platform with lifting and lowering hydraulic cylinders, articulated supports mounted on it by a screw, front and rear cleaning drums, a casing connected by adjustable rods to the copying platform, an “attack” angle indicator, while the rear drum of the cleaning device is mounted from a screw in the case of the copying platform, the casing with the front stripping drum mounted in it is connected to the copying platform with the help of yokes with the possibility of rotation relative to about them, and the scale for indicating the angle of “attack” is kinematically connected with the height indicator of the rear drum mounted on the copy platform above the harvested field surface. (patent of the Russian Federation No. 2373681, CL A01D 41/08, 2006).

The disadvantage is the complexity of the design, the large weight and bulkiness of the device, as well as the high energy costs associated with the need to drive two drums.

The closest in technical essence and the achieved effect and accepted by the authors as a prototype is a device for combing grain on the root, including a header mounted on a tilting chamber of a combine harvester, containing a receiver and two cheeks, and also a brushing rotor mounted between them, equipped with uniformly distributed brushing elements in the form of plates with cut out combs of stripping pointed fingers, an inclined belt conveyor, a screw and a drive located in the receiver, the conveyor being equipped with scratching elements, and the rotor is made of a double drum with a chain contour, in which the lower branch is installed parallel to the upper branch of the conveyor, and the stripping elements are fixed through elastic strips having a height greater than the distance between the conveyor and the rotor, while the plates of the brushing elements with a comb of fingers are made of metal and have a concave shape, and the fingers have a width greater than the cutout between them, and the drive provides counter rotation of the conveyor and rotor, (patent of the Russian Federation No. 2306691, class A01D 41/08/2006).

The disadvantage is the complexity and massiveness of the design, as well as grain loss caused by knocking it out of the spike with elastic straps and trapping the combed mass with combs at the end of the towing.

Disclosure of invention

The technical result that can be achieved using the present invention is to reduce crop losses during harvesting and simplifying the design.

The technical result is achieved by the fact that in the device for harvesting crops with a standing vine, including a header mounted on a tilting chamber of a combine harvester, containing two cheeks, as well as a screw and a combing rotor mounted between them, equipped with evenly distributed combing combs, the rotor is single drum and has cylindrical shape, and combs have a flat shape and are mounted on rotating rods, at the ends of which leashes with rollers are installed, rolling on a run new tracks.

The novelty of the proposed solution is due to the use of flat stripping combs and their installation on the rods, turning in hinges, as well as the connection of the rods through leashes with rollers with treadmills mounted on the cheeks and having such a shape that allows the combs to enter the plant mass in a vertical position in order to avoid knocking out grain from the ear and the comb coming out of the working area also in a vertical position, which prevents capture of the stripped mass and its transfer through the stripper the rotor and the direction of the mass in the header under the auger.

The implementation of the invention

A device for harvesting crops with a tuft at the root, including a header 1 mounted on an inclined chamber (not shown), containing two cheeks 2, a screw 3, and a combing rotor 4. Support discs 6 are mounted on the bearing shaft 5 of the combing rotor 4. The discs 6 are evenly mounted on the discs 6 hinges 7 are installed on the periphery, in which the rods 8 are installed, with combing combs 9 fixed to them, having the form of a flat plate with rectangular fingers pointed out at the end 10, the width of which is larger than the gap 11 between them. At the ends of the rods 8, leashes 12 with rollers 13 are rigidly fixed, which roll along the treadmills 14, mounted on the cheeks 2. Each of the treadmills 14 is a closed loop formed by a] -shaped beam. The shape of the contour is selected in such a way as to ensure the vertical position of the comb 9 at the entrance to the bread stand, the inclined position, which eliminates the possibility of the ear slipping out of the slot at the time of towing and turning the comb to a vertical position at the end of the towing. The rotor 4 is installed in the supports 15, mounted on the cheeks 2.

A device for harvesting crops by tow on the vine works as follows.

The device is hung on the inclined chamber of the combine and moves with it along the field. Heder 1 introduces its cheeks into the bread mass. The stripping rotor 4 rotates towards the header of the combine. In this case, the rollers 13 are rolled along the treadmills 14 and, using leashes 12, the rods 8 are turned 8. Thus, the rollers 13 describe a trajectory that repeats the contour of the treadmill 14. During the rotation of the stripping rotor 4, when the comb 9 approaches the plant mass, it occupies a vertical position. This is due to the position of the leash 12, which is an intermediate link between the rod 8 and the roller 13, which rotates as a result of the difference in the trajectories of the rod 8 and the roller 13. When entering the bread-comb, 9 separates a portion of the plant mass and brings it to the header 1, while the leash 12 rotates with comb 9 in the direction of rotation of the rotor 4, and the stems of the plants fall into the slots 11 between the fingers 10. At the time of being above the header 1, comb 9 occupies an inclined sliding position, preventing the spike from slipping out of the slot 11, and the crop at this time abuts the header 1. On further rotation of the rotor 4 comes ochesyvanie ears. Combed mass under the action of inertia created by the combs 9 of the rotating stripping rotor 4 is thrown into the header under the screw 3. In order to avoid capture of the plant mass by comb 9, at the end of the towing process, the latter rotates and takes up a vertical position as a result of the position of the leash. When the comb is in the upper position, the bar 11 rotates around its axis, so that when approaching the bread mass, the comb 9 again takes up the necessary vertical position.

Compared with the prototype and other technical solutions, the invention has advantages:

- reduction of grain losses;

- simplicity and reliability of the device;

- low power consumption.
