Description

one

The invention relates to the field of agricultural engineering, in particular to devices for forming bales of hay and straw.

A device for forming rectangular bales of hay and straw, comprising a frame, a sub-compactor, made in the form of two spring-loaded rollers installed with the possibility of counter-rotation, a rectangular chamber, one of the walls of which has a window 1.

A disadvantage of the known device is the unevenness of the density of the material in the bale, as a result of which the strength of the bale is reduced and its shape is disturbed.

The purpose of the invention is to increase the uniformity of the density of the material in the bale.

This goal is achieved by the fact that the chamber is installed with the possibility of forced swing relative to the subpress driver with an amplitude limited by the height of the chamber, and the wall with the window is fixed on the frame and made swinging along the arc of the chamber overlapping its cross section .

The drawing schematically shows the proposed device.

It consists of conveyor 1, lower and upper, rollers 2 and 3, chambers 4 of rectangular cross-section, the front wall 5 of which is made with a window. The upper drum 3 g is mounted on levers 6 and pressed to the lower drum 2 by springs 7. Camera 4 is fixed on hinges 8 and associated with a drive mechanism consisting of a crank 9 and a connecting rod 10. A wall 5 with a window is fixed independently of the camera body 4 on Frame I. Output part of the rollers 2 and 3 is installed in the window of the wall 5 of the chamber.

The device works as follows.

Conveyor 1 feeds material to rollers 2 and 3, which, rotating towards each other, press the material layer under the action of springs 7 and push into chamber 4 through a window in the front wall. The chamber 4, using a crank mechanism, oscillates relative to the rollers 2 and 3 and the fixed front wall 5 of the chamber 4, swiveling 8, thereby pushing the compressed material layer pushed by the rollers 2 and 3 across the chamber 4 and kept in a compressed between the front wall 5 and the material layers previously distributed in the chamber.

As the chamber fills, the layers of material advance along it. The process of bale formation continues iyeryryvio.

This device provides a more uniform density of the material in the bale.
