VEGETABLE HARVESTER Russian patent published in 1997 - IPC

FIELD: agricultural engineering, in particular, harvesting of fleshy vegetables and onion. SUBSTANCE: harvester has undercutting working tools 1 with elevator 2, transfer drum 3 with eccentric extensible fingers, finger cleaner 6, sorting out longitudinal and discharge conveyors 10,11,12 and fruit separator with succession of drums 9 with extensible fingers. Maximum departure phase of fingers of drums 9 of fruit separator is less than that of fingers of transfer drum 3. Drums 9 of fruit separator are provided with drive, which provides acceleration of rotational speed of drum 9 in opposite direction relative to elevator 2. Body of each subsequent drum 9 is positioned above the previous one. Triangular cleaner 6 is positioned in front of cylindrical brush 7. One apex of cleaner 6 is directed upward and is provided with belt tightening mechanism 8 positioned below belt. Cleaner belt coming down run inclination exceeds or is equal to fruit friction angle. Brush drum 7 is mounted below cleaner lower generatrix and may be regulated in longitudinal direction. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 2 dwg
