FIELD: agriculture.

SUBSTANCE: invention relates to a mobile device for cleaning grain and seeds, in particular to a device for use in cleaning seeds of cereals, legumes and industrial crops. The mobile grain cleaning unit includes a receiving hopper with a scraper conveyor, a loading elevator with a device for separating coarse and large impurities, a centrifugal-air separator with an annular pneumatic separating channel, an intermediate elevator and a secondary cleaning machine MVU-1500, containing an air cleaning part with the first and second pneumatic channels with valves for pre-sieve and post-sieve aspiration, three sedimentation chambers, two sieve mills operating in series, and a fan, a final elevator, a final cleaning machine MOS-9N. The fan of the MVU-1500 secondary grain cleaning machine is connected to it by means of a branch pipe in the upper part of the end wall of the second aspiration channel. The post-sieve aspiration valve is located in the working area of the second channel and the third sedimentary chamber. The exit of grain fraction from the third sedimentary chamber of the secondary cleaning machine MVU-1500 is connected by a grain pipeline to a distributor valve. One of the outlets of the distributor valve is connected in series through the intermediate auger and the final elevator to the final seed cleaning machine MOS-9N, and the other outlet of the distributor valve is connected to the light fraction outlet of the final seed cleaning machine MOS-9N.

EFFECT: improving the quality and increasing the yield of seeds of the sowing standard.
