MACHINE FOR HARVESTING ROOT VEGETABLES AND ONION Russian patent published in 2019 - IPC A01D17/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural machine building. Machine comprises frame (1), undercutting plow (2), running wheels (3), screwing mechanism (4) for adjusting the depth of digging, disc knife (5), main (6) and auxiliary (7) separating elevators, tops stretching (8) and supporting (10) rollers, cylindrical cleaner (11) of soil impurities with receiving roller (12), convergent tray (13), former-scraper bar, roll maker (14), tops remover (15) of vegetal impurities and reduction gear (16) of working elements. Undercutting plow (2) is made with support plate, guides and rods with pushers. Auxiliary bar separation elevator (7) is arranged on electric cylinders (17) and is made in the form of shakers (9) and supporting (10) rollers located on both sides with alternation along length and width and mismatch phases of their lifting and lowering. Cylindrical cleaner (11) of soil impurities is made with possibility of rotation towards side of bulbs passing, receiving roller (12) – with possibility of rotation in opposite direction. Former-scraper bar is made with spiral periphery along its entire length with cross-section in the form of a segment with the same angular pitch and height of lifting. Beginning and end of each coil are located on one cylinder generatrix with offset.

EFFECT: higher quality of work during harvesting by 5–7 % and reduced injury of root and tuber roots and onions.
