Description

2, The baler according to claim 1, wherein the crank is bounded on one side by an abutment, on the other by a spring,

3, A baler in accordance with claim 1, wherein the barrier The invention relates to agricultural machinery and can be used in technological processes of harvesting, intended for use in machines. for harvesting feed.

The aim of the invention is to increase press productivity by automating the pressing process.

Figure 1 schematically shows a round baler; Fig. 2 is a kinematic diagram of the binding mechanism.

The device contains a loading window 1 associated with the moving means 2. The pressa pressing device is an endless belt 3, thrown over the system of rollers 4-7 and forming a loop 8. The rollers 5 and 7 are fixed on the frame 9 of the press, and the rollers 4 and 6 are on the pivoting levers 10 and P. The lever 10 associated with a tensioning device, which is made in the form of a hydraulic cylinder 12 connected to a hydropneumatic accumulator. At the beginning of the roll forming process, the lever and the roller 6 are fixed by means of the latch 13. The delivery conveyor 14 rotates on the rollers 15-17. A clamping mechanism 18 is mounted to press the rolls into the press. To prevent the weight from winding over the twine and not to stop the baler for these purposes, a damper 19 is installed in front of the loading window I, which is pressed to the stop 21 by the spring 20 in the process of forming the roll, One of the ends of the damper 19 is connected the traction element 22 with the friction drum 23 rotating on the axis of the crank 24 (FIG. 2), is jarn-coupled to the lever 10.

The ka is mounted on a horizontal axis across the direction of the entry of this material and is limited to one side by an abutment, while its end associated with the friction drum is spring-loaded,

On one of the sides, Krivoshchep 24 is limited by an abutment 25, to which the spring 26 presses it. The axis of the 18-linking mechanism 18 is rigidly connected to the friction-disk 27,

The device works as follows.

To activate the mechanism 18, the lever 10, turning, pushes the lever 28, the mass enters the feed conveyor 14, which feeds it into the zone of the loop 8, where it is twisted into a roll of rotating form

And press belt 3. As the diameter of the roll increases, the roller 4 approaches the roller 5. At the same time, the pressing density is achieved by counteracting the hydraulic 1) cylinder with the roller 4 and the friction drum 23 by turning the lever 10 and pressing the lever 28 and Includes a latch mechanism 18. At the same time, the friction drum 23 is pressed against the friction disk 27. Consequently, together with the rotation of the wrapping mechanism 18, the friction disk 27 also rotates, which, due to the forces of friction, causes the friction drum 23 to break in. Iri rotation of the friction drum 23 winds it onto the flexible element 22, which, interacting with the flap 19, translates it into a position that overlaps

Straw feed to feed conveyor. After the roll is tied with the clamp, the latch 13 opens and the clock 11 is ejected by turning the lever 11 clockwise.

devices. After that, the rod of hydrocyles I Vdra 12 returns to its original position by moving the lever 10 which separates the friction drum 23 with the friction disk 27 ,.

as a result, the spring 20 returns 11 and the latch 13 locks it in retracting the damper in the barrel position. The process of forming- 19. At the same time the lever is lowered, no rolls are repeated.
