Description

The known devices for compressing straw materials do not provide continuous pressing as the straw mass is received.

A distinctive feature of the proposed device is continuous pressing of straw materials as they are thrown from the thresher. This goal is achieved by using rotating forks and a rotary comb, which at each turn through the pusher shifts to one or the other side of the forks.

FIG. 1 shows a side view of the device; in fig. 2 shows a section along AA ka of FIG. one; in fig. 3 - s.hema harpoon guide; in fig. 4, 5, 6, 7 - phases of movement of the comb (Fig. 4 - beginning of compression, Fig. 5 - continuation of compression, Fig. 6 - end of compression, Fig. 7 - movement of the comb along forks along the axis).

The chamber / devices are mounted on racks 2 and illuminated behind the combine. In the bushes of the uprights, the forks 5 are rotated, provided with holes along which the comb slides with its teeth 4 rigidly connected to the axis 5 having shock absorbers 6. The shaft / pusher S and the forks are interconnected by gears and, with the help of a chain, driven by a combine . Along the chamber, the guide 9 with the harpoons 10 freely moves along the grooves of its side walls.

The operation of the device is as follows.

The threshing-fed straw is stuffed with a comb into the curved cavity and retained by the camera with latches, after which the comb moves the punch through the forks of the fork, continuing to force the other ends of the teeth. Thus, with each turn, the comb moves either to one or the other side of the forks, due to this the BS occurs; the sprinkling process occurs. The degree of compression is governed by the taper of the chamber.

 The performance of the seal depends on the rotational speed of the forks. When feeding 10 tons of straw per hour, one bale per minute is pressed. There is enough time for the handwind of the straw strings. Puncturing the straw mass with the harpoons, the zal'shik puts a pass on the harpies, tightens it crosswise and ties it in a bag. While operating with string or wire, the process can be mechanized by a conventional in a clamping apparatus. The decorated bales are dumped into a cart hitched to the rear of the combine. Moisture-rich bales are made multihole, blowing through special breakdowns.

The subject matter of the invention 1. Attachment device for pressing straw materials with large bales, driven from the drive of the combine by gears and chains, characterized in that, in order to ensure uninterrupted grinding of straw materials as they are thrown out of the thresher, rotation of the fork and rotary tool are used. a comb, which at each revolution moves through the pusher to one or the other side of the forks.

2. The form of embodiment according to claim 1, characterized in that, due to the nature of the operation of the pressing mechanism, the pressing chamber is bent and its cavity in cross section has a rectangular shape.
