APPARATUS FOR INTENSIFIED SEPARATION OF GRAIN FROM COARSE HEAP Russian patent published in 1996 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has conveyor and fingers. Conveyor is formed as beater with hollow shell. Fingers are arranged in at least one row above conveyor and oriented downward with their tips. Space between fingers is less than maximum working space between conveyor and pressure member. Fingers may be adjusted. Distance between fingers and upper restricting surface in zone between pressure member and row of fingers exceeds space between conveyor and row of fingers. Finger tips of pressure member are oriented toward conveyor and upper restricting surface is rigidly connected with row of fingers. EFFECT: increased efficiency, intensified separation of grain and enhanced reliability in operation. 2 cl, 2 dwg
