Abstract

The invention relates to agricultural machinery and, in particular, to self-propelled combines equipped with devices for the accumulation of haymaking materials. The purpose of the invention is to reduce the weight of the combine and increase its longitudinal stability. The self-propelled combine harvester 2 contains a bale press keeper 1 for haymaking materials installed in its rear part, the drive of which is kinematically connected with the drive of the mechanisms of the combine. The press keeper is provided with a bracket fixed on the front part of its frame with a support pin interacting with the ball bearing, which is made in the middle on the rear axle of the chassis of the combine. The kinematic connection of the press hopper with the motor shaft of the combine is made in the form of a volumetric hydraulic drive. When harvesting a strawberry, part of the mass enters the baling press stacker, where a bale is formed from it. Upon completion, the bale is dropped to the ground. 3 hp f-ly, 4 ill.

The invention relates to agricultural machinery, in particular to self-propelled combines equipped with devices for the accumulation and compaction of haymaking materials.

The purpose of the invention is to reduce the weight of the combine and increase its longitudinal stability.

FIG. 1 schematically shows the rear part of the front of a self-propelled combine harvester, a general view; in fig. 2 shows an attachment unit for the bracket to the front of the frame of the press-stacker and its connection with the ball bearing of the rear axle of the combine; in fig. 3 - installation of a ball bearing on the rear axle of the combine; in fig. 4 is a flow chart of the passage of hay-straw material.

The press locking device 1 is installed in the rear part of the combine 2 instead of the accumulator and fixed on the bolts with its sidewalls 3 with help, installed on both sides of the delivery 4 on the tail part of the thresher housing 5. On the front of the frame (3 press stoppers, represented by a pipe, at the ends of which are with the possibility of a vrash, are mounted the stands of 7 support wheels, with the help of three clamps 8, the bracket 9 is rigidly fixed The front end and electrically welded to the support pt 10 folded three angular profiles fan-shaped.The bracket 9 with its front end with the support pt 10, on the lower side of which the spherical hinge cage is integrally formed, interacts with the ball bearing 11 of this hinge, secured bolted on shelf 12, welded by electric welding in the middle to the beam 13 of the rear axle of the undercarriage of the combine harvester 1. Geometrical longitudinal axis A of the spherical hinge swing when installing the ball bearing 11 is complete with the axle of the rear axle swinging around the combine frame axis ( not indicated).

The drive gear of 14 working bodies of the press stopper 1 is kinematically connected with the shaft of the engine 15 of the combine harvester 2 by means of a volumetric hydraulic drive. The high-pressure pump 16 of the hydraulic drive is mounted on the left transition area of the combine 2 and is connected by a cardan transmission through a coupling, a pulley and the drive shaft of the threshing machine (not shown) of the combine 2 with the shaft of its engine 15. The hydraulic motor 17 of the hydraulic drive is fixed on the frame 6 of the press digger 1, is connected by cardan transmission through a friction clutch (not shown) to the drive gearbox 14 of the working bodies of the press stopper 1 and flexible high-pressure pipelines 18 to a high-pressure pump 16 a.

The high-pressure pump 16 of the hydraulic actuator is controlled and provides a change in the number of revolutions of the hydraulic motor from 50 to 2590, as well as its reversal and shutdown.

Under the straw catcher 19 and the comb-winder comb 20 of the combine harvester 2 between the side spacers 4 in the transverse direction and between the rear lower part of the combine 2 on the one hand and the receiving chamber of the press digger on the other hand, the directional tray 21 for the floor is sealed in the longitudinal direction . In order to increase the efficiency of the grouper 20, three wooden rails-pushers 22 fixed at an acute angle to the plane of the guide tray 21 and resting on it with their front (lower) ends are fixed with the help of clamps on its shaft.

The proposed self-propelled combine harvester works as follows.

In the process of processing the ground mass, the mechanisms and apparatuses of the combine 2 haymaking material from the straw walker and chaff by means of a polisher 20 and pusher bars 22 in the guide tray 21 are fed into the receiving chamber (not indicated) of the press-smoker, where they are compacted and rolled into a roll-shaped cylindrical bale. After the press bale chamber is filled, the cylindrical bale is automatically pushed out.

The static load from the mass of the press stopper 1 and the hardened material accumulating in the press chamber, as well as the dynamic loads from these moving masses during the movement of the combine 2 are perceived by bolted joints between the sides 3 of the press hopper 1 and spacers 4 on one side and also bolted connections between the spacers 4 and the tail part of the body 5 of the threshing apparatus of the combine 2 on the other hand. The above-mentioned bolted joints are significantly unloaded by transferring the bulk of the load from the mass of the press stopper and hay material through the arm 9, mounted on the front of the frame 6, and the ball bearing 11 directly onto the rear axle of the combine chassis 2.

When the rear axle beam 13 rotates around the longitudinal axis B of the combine frame, caused by the movement of the combine on an uneven surface, the ball bearing 11 fixed on the shelf 12 of the rear axle beam 13 is rotated unhindered since the geometrical axis A of its rotation coincides with axis B swing rods 13 rear axle combine.

If necessary, the exact installation of the ball bearing 11 to the coincidence of the geometrical axes A and B is carried out with the help of shims.
