The invention relates to agricultural production and is intended for the pure selection of grain at the currents and elevator sites after the removal of the heaps, as well as at the bread hauling routes.

The purpose of the invention is to enhance the functionality of the pick-up.

The drawing schematically shows the proposed grain selector, a vertical longitudinal section.

The grain picker contains a frame 1 with wheels 2, on which an intake device in the form of a screw 3, mounted on supporting plates (not shown) in the casing 4, which includes the lower (final) part of the loading conveyor 5, terminating in the upper part of the flexible the sleeve 6 entering the receiving bin 7. Behind the casing 4 there is a brush drum 8 with rotation, reverse to the grain picker movement, to the front lower part of which the wall 9 of the casing 4 is bent, and to the front upper part offset from behind wearing to the wall 9, the end part of the reflector 10 located above the intake device 3 and forming together with the wall 9 an opening 11 in the housing 4. For loading grain from the collar, windows 12 are provided in the front part of the housing 4, which are closed by the flaps 13.

The grain collector works as follows.

The selection of grain can be carried out simultaneously with its loading from the pile and as an independent process during the stripping of currents and grounds or the selection of grain on the roads after its loss from motor transport. When picking up grain, simultaneously with loading from the pile, windows 12 are open, and when picking grain from roads and platforms, windows 12 are closed with flaps 13. Grain picker

Zhets towards the cleaned site. The intake device 3 and the brush drum 8 are rotated from the conveyor motor or from the wheels 2. The grain, the passage below the bottom of the casing 4, falls under the edge of the brush drum 8, which rotates towards the grain. The villi of the drum 8 pick up the grain and direct it along the bent wall 9 of the casing 4 to the opening 11, through which it enters the intake device 3. The reflector 10 prevents the grain from passing beyond the opening 11. The intake device 3 shifts the grain to the entrance to the casing 4 the end part of the loading conveyor 5, 5 with the help of which the grain is transported through the sleeve 6 to the receiving bunker 7. When loading and selecting grain at the same time, the conveyor 5 is extended using additional sections and then the sleeve 6 is put on the end section and Rno collected in the back of a vehicle.
