FIELD: agricultural engineering. SUBSTANCE: combine has digging shares, separating working tools containing rod-type conveyor and drum enclosed in another rod-type conveyor. Drum has flanges. Working surface of rod-type conveyor, which embraces drum, is equipped with inclined pins staggered in the course of advancement of conveyor at spacing, which may be determined from expression: H=4h, where H is pin pitch; h is rod pitch of rod-type conveyor. Linear speed of rod-type conveyor equipped with pins is equal to that of drum. EFFECT: increased efficiency, improved separation of roots and tubers from soil and reduced damage and loss of tubers or roots by improved removal of tops. 3 cl
