GRAIN HEAP SEPARATOR Russian patent published in 2018 - IPC A01F12/44 

FIELD: agriculture; mechanical engineering.

SUBSTANCE: invention relates to agricultural machine building and can be used for cleaning and sorting grain. Grain heap separator includes a body, a charging device, a cylindrical sieve mounted on bearing supports, a rotor that contains a shaft on bearings and mounted on the blade shaft. Shaft of the rotor is tubular, and the rotor blades are made in length of less than the sieve length. Inside the tubular shaft there is an axle, which is fixed to the body motionless. Front bearing support of the cylindrical sieve is mounted on the tubular rotor shaft, and the rear bearing on the fixed axle. At the end of the sieve axis, a brush device is installed.

EFFECT: invention improves the quality of cleaning the grain heap by increasing the completeness of separation of large and small impurities, improves productivity by cleaning the surface of the inner sieve, reduces the complexity of changing the sieves, maintenance and repair.
