GRAIN-SEPARATING MACHINE Russian patent published in 2017 - IPC B07B1/24 

FIELD: agriculture.

SUBSTANCE: grain-separating machine includes a cylindrical sieve and a distribution rotor with a helical spiral. The cylindrical sieve is mounted with the possibility of rotation and with a slope to the horizon in the direction opposite to the axial movement of the separated grain. The distribution rotor with a helical spiral is located inside the cylindrical sieve with the possibility of rotation in the direction opposite to the sieve rotation direction. The helical spiral of the distribution rotor is mounted on longitudinal plates fixed radially or at an angle to the rotor radius. The clearance between the longitudinal plates and the inner surface of the cylindrical sieve in the ear sieve section location area decreases to the sieve end.

EFFECT: machine ensures efficient cleaning and sorting of grain.
