The invention relates to agricultural machinery and can be used in combine harvesters for collecting and transporting grain chaff, leguminous crops, and grass seed plants to trailer trucks.

The purpose of the invention is to reduce energy consumption and make the process more reliable.

FIG. 1 shows a half-cupboard, side view; in fig. 2 is a section A-A in FIG. one. ,

A polovosbornlk consists of a screw 1 with double-sided spiral winding placed in casing 2 with a loading window B, which is equipped with pipe 3 and a flap 4, exhauster 5 with pipe suction 6, piping 7, mechanisms 8 driven. At the same time, the front edge of the casing 2 of the screw 3 adjoins the tray of the policeworker 9 and the exhauster 5 is displaced relative to the screw 1 downward, which ensures the inclined position of the suction nozzle 6. The cylindrical part of the funnel 10 has slots 13 J inclined to the axis, which ensure a smooth change in the annular gap B. In the desired position, the funnel 10 is fixed by a latch 12.

On the shaft of the screw 1 in the zone of the discharge window B is fixed two blades 13, installed axially. All working bodies by means of brackets are mounted in the frame-spoke 14 attached to the tail section 15 of the combine, in which the hood 16, is also fastened.

Half collector works as follows.

The last rake is fed into the casing 2 of the screw 1, the double-sided winding of which provides it to the boot window B of the casing ,, Then the blades 13 of the screw 1 throw the chaff through the upper part 3 of the suction port 6 into the zone of the annular gap B through which air enters. Due to the pinch effect, a sex-to-air mixture is formed. A homogeneous mass concentration, which is sucked into the exhauster 5 and transported by the latter along the pipeline 7 to the trolley 17.

The straw coming from the straw walker 18 is guided through the hood 16 into the rectangular opening of the spoke frame 14 and placed behind the stubble & continuous roll.
