SEED-CLEANING MACHINE Russian patent published in 2009 - IPC B07B1/22 

FIELD: agriculture.

SUBSTANCE: proposed seed-cleaning machine has loading and unloading apparatus, a rotary actuator joined to a drum, made from one perforated band, bended along straight fold lines, located at an angle to the edges of the band, wound up into cylindrical coils, joined to each other along linear edges, with formation on the outer surface of unidirectional broken helical lines, and on the inner surface - broken helical lines of the pockets of the drum. The pockets along the perimeter are in form of geometrical figures with a polygonal or curvilinear shape. For pockets of the drum with curvilinear shape, the distance between the straight fold lines is equal to the sum of the length of perimeters of the geometrical figures of pockets on the inner and outer surfaces. For pockets with polygonal shape, the distance between straight fold lines is equal to the length of each element of the polygon.

EFFECT: increased efficiency of cleaning seeds; widening of functional capabilities.
