SU869646A1 - Device for separation of cotton mass in cotton harvester hopper - Google Patents

Description

one

The invention relates to the field of agriculture and can be used in cotton harvesting and cleaning machines.

A device for separating cotton mass in a cotton harvesting bunker is known, which comprises a frame fixed in the bin lid, made in the form of a curved frame with cantilever parallel rows installed along the movement of cotton mass and grate placed on transverse supporting elements.

A disadvantage of the known device is the clogging of the grate sections with cotton fibers during the cotton mass separation process, which leads to a reduction in the weed removal effect during the cotton picker operation time.

The aim of the invention is to increase the efficiency of separation of cotton mass.

The goal is achieved by the fact that a device for separating cotton mass, containing a skeleton secured in the bunker lid, made in the form of a curved peiMH with cantilever parallel rows installed along the movement of the cotton mass and placed

on the transverse supporting elements with ridges, equipped with fender visors mounted on the transverse supporting elements with the ability to interact with the grate bars of the previous row regarding the direction of movement of the cotton mass, while the peaks are spring-loaded, and the surface of the peaks contacting with the grate bars is made of cotton.

FIG. 1 shows schematically a device for separating cotton mass in the hopper of a cotton harvesting tire 15, side view; FIG. 2 is the same, top view, in FIG. 3 is a section A-A in FIG. 1, in FIG. 4 is a section BB in FIG. 3

A device for separating cotton 20 in the bunker of a cotton harvesting machine contains a frame 3 fixed in the blade 1 of the bunker 2, made in a fork of a curved frame with cantilever parallel rows installed

25 along the movement of the cotton mass and the grate 5 placed on the transverse support elements 4, The device is equipped with fender visors 6 mounted on the transverse support

Claims (1)

30 zlementah 4 with the ability to interact with the grate 5 of the previous row relative to the direction of movement of the cotton mass, while the peaks are equipped with spring elements 7, and the surface of the peaks 6 in contact with the grates 5, is oval. The device works as follows (at a time. The cotton air flow enters the separating device and the cotton segments under the action of aerodynamic forces, interacts with the grate 5, weed impurities and loose fibers are released, which are carried away outside the device. adhere to the grate bars 5. The bouncing visors 6 and the grate bars 5 of the previous row, when interacting with each other and under the action of the cotton-air flow and the spring elements 7, vibrate, which improves the separation. The fact that the surface of the visors 6, which is in contact with the grate 5, is oval-filled, the free cotton fibers do not get stuck on the surface of the visors 6 and are carried away beyond the top of the cover 1 to the top or re-enter the corridor of the separating device. machine allows to increase the efficiency of separation of cotton mass due to vibration of the fender visors, interacting with the grate. Formula of the invention. A device for separating cotton mass in the cotton harvest bunker A carcass containing a frame secured in the lid of the bunker, made in the form of a curved frame with cantilever parallel rows along the movement of the cotton mass and grate bars placed on the transverse supporting elements, characterized in that, in order to increase the separation efficiency of the cotton mass, it is provided with baffles mounted on transverse support elements with the ability to interact with the grid bars of the previous row relative to the direction of movement of the cotton mass, while the visors spring-loaded, and the surface of the visors, in contact with the grate, is oval.
