DEVICE FOR GRAVITY DISTRIBUTION OF LOOSE MATERIALS Russian patent published in 2010 - IPC B07B11/06 

FIELD: process engineering.

SUBSTANCE: invention relates to loose materials distributors, for example distributors of grain over grain cleaning machine width. Proposed device comprises receiving device housing with loading hole, housing pitched surface and pneumo-separating channel. It comprises a spout communicated with receiving device housing and arranged above the chute top part. Said pitched surface represents a tapered surface segment with trapezoid outline with its smaller base directed toward loading hole and larger base directed toward pneumo-separating channel and arranged at the angle equal to or larger than friction angle that allows no-drew grain flow over pitched surface. Pneumo-separating channel consists of inclined and vertical sections. Vertical sections has opening with shutter screen and reflecting crest arranged below material intake point.

EFFECT: uniform feed of grain heap into pneumo-separating channel, higher quality of grain.
