Description

The invention relates to the field of agriculture, and in particular to agricultural harvesting machines.:.

A self-propelled MPU harvesting machine is known, including a pick-up, a reaper, conveyors; mass grinder, hydraulic and mechanical controls for working units, engine and. code part and full trailer.

;: -. . . - .. - .. /. - -V - i:, -.... . The disadvantage of this technical solution is that during combine harvesting, the cereal mass or seed plants of perennial grasses are crushed along the unit (where sharply, threshed there). The ground mass is conveyed by an air conveyor to the PTO-4 trailer. Loss of grain due to the unit moving along an uneven field.

The closest in technical essence and selected as a prototype is a technical solution for autosw. USSR No. 1496684.cl. A01D 41/00, 1987.

An object of the invention is to increase productivity by densely loading a towed container.

The goal is achieved in that an agricultural harvesting unit containing a pick-up, a reaper, conveyors, hydraulic and mechanical controls for the working units, an engine, a chassis and a drive chassis, the unit having a tow hitch with a movable position saddle in its layout automobile type, the pressing mechanism working in the horizontal plane, the body of the long trailer is made with variable volume, the towbar has two guide beams - in the twin apertures - sleeves, two runner - HA rulers seat locking and disconnecting device driven by a double-acting hydraulic cylinder mounted at the rear portion for lifting

The pressing mechanism has a rake-shovel, two pushing beams - a frame pivotally mounted on a tractor, and two double-acting hydraulic cylinders; a movable hook with a hydraulic cylinder is installed on the side of the working plane of the rake-shovel.

Comparative analysis with the prototype shows that the claimed agricultural harvesting unit is characterized in that it has a tow hitch in its layout with a mobile positional saddle of the Automobile Type, a pressing mechanism working in a horizontal plane, and the length of the lengthy trailer body is made with variable volume. :; .:. ; ..., .. .., ..

Thus, the inventive agricultural harvesting unit meets the criteria of the invention of novelty,

Comparison of the claimed solution not only with the prototype, but also with other technical solutions in the given technical field Нy made it possible to reveal in them the features distinguishing the claimed solution from the prototype; which allows us to conclude that there are significant differences between the criteria.

The agricultural harvesting unit includes a combine harvester 1 (Fig. 2) having a header 2 mounted in front, a driver's cab 3 is located at the top in front of the frame of a combine harvester 1, engine 4 is located behind cab 3. T tow hitch 5 is located on the rear frame of the combine 1. The towing device 5 includes (FIG. 3) a car-type seat 1, which is located on the load-bearing beams 3, which in turn are fixedly mounted on the guide rails x 11. The slide rails 11 move along the traction and direction to the beams 4. The position of the guide rails 11 on the traction guide beams is fixed by the pivots 7, which enter the bushings 19. Between the traction guide beams 4 there is a square shaft 13, one end of which interacts through the lever with the power double-acting cylinder 12. On a square shaft 12 (see figure 4)

the clutch 14, the disk-arm 15, which is connected by the chain 16 to the fork 17, are arranged to move. For loading the beveled mass into the semi-trailer on the combine 1 (Fig. 2), there is an inclined conveyor 8. For a more complete loading the semitrailer, without lowering the maneuverability of the combine-1 tractor, there is a sub-pressing mechanism on the combine-tractor, including a shovel

5, the rake 11, which is pivotally mounted on the body of the combine harvester and moves in the vertical plane with the help of the power cylinder 10, and the semitrailer itself (see Fig. 5) is made with a variable net volume. The rear part of the semitrailer is set by mesh fixed panels, the front half is equipped with mesh panels that move along the guides, made -.

Agricultural harvesting unit (see figure 1) operates as follows: ЗР.М-:.: О ;; / - ;,; ; . WITH--. .-

0 The skewed header brings the mass through the conveyor 8 to the semitrailer. The semi-trailer is attached to the saddle 6, which at the beginning of operation is in the extreme front position. Movable mesh volume

5 is shifted in the guide as far back as possible. As the semi-trailer is sloped, the movable mesh volume shifts in the direction of travel of the combine by moving the saddle back. Saddle

0, however, should shift in the opposite direction. To accomplish this, the combiner on the move acts by means of a power cylinder 12 (see Fig. 3) through the lever on the square shaft 13, turning

5 clockwise, while the square shaft 13 in turn rotates the clutch 14 together with the disk 1S using the pull chain 16 and the yoke 17. The pivots 7 are pulled out of the bushings 19, resulting in a seat 6

The pressing of the beveled mass into the semi-trailer is carried out as follows. Having stopped the harvester-t gach 1, the saddle 6 is released from fixation, lower the rake shovel 11 and the cylinders 10, informing the combine-t gach 1 backward, with the help of the grab-shovel 11 the mass is pressed.

After filling with the mass, the semi-trailer is disconnected from the tractor unit 1 and transported by a vehicle equipped with a saddle to a hospital where the mass is threshed and the empty semi-trailer is automatically attached to the tractor unit 1.
