FIELD: agricultural engineering, in particular, grain cleaning technique, may be used in various fields of economy for cleaning of bulk materials.
SUBSTANCE: apparatus has electric engine, cylindrical hopper, screen, discharge branch pipes, and fixing mechanism. Hopper is adjusted by means of hopper casing inclination angle regulator and is equipped with two exits for cleaned and basic grain, respectively. There is rotating cylindrical screen within hopper, with rotational velocity of cylindrical screen being regulated. Screen cleaning brushes are attached to hopper inner wall.
EFFECT: improved quality of grain cleaning, increased efficiency and reduced grain losses during separation procedure.
