摘要：
FIELD: agriculture.SUBSTANCE: invention refers to: agricultural machine building, in particular, to machines for cleaning and sorting of tuber crops and fruit. The device comprises an inclined feeder, a receiving chamber and two cylindrical drums, upper and lower ones, made of longitudinal bars. Drums are installed in series one after the other, at the angle to the horizontal plane. Drums are given harmonic oscillations in the vertical plane that matches with the longitudinal axis of the drums. On the free ends of the drums along the surface of longitudinal bars of both drums there are shells installed. Stops are installed along the circumference of the shell of the upper drum symmetrically relative to each other. The surface of each stop is arranged in the form of a flat circle segment. The pitch of installation and height of stops are chosen with account of the shape of the processed material and extent of contamination. Each shell of two cylindrical drums, upper and lower ones, rests against two rollers arranged symmetrically relative to the longitudinal axis of the two drums. The axis of each roller is parallel to the longitudinal axis of both drums and is deviated from the longitudinal axis of the drums by the angle α. A crosspiece with a flange is fixed to the shell of the lower drum. The axis of the flange matches the axis of two drums. A flange of a slave shaft of the drive of both drums is fixed to the flange of the crosspiece of the lower drum.EFFECT: invention provides for improved evenness of potatoes distribution among fractions, higher percentage of sorting and possibility of using a heap of tuber crops with partial contamination of soil admixtures.3 cl, 4 dwgИзобретение относится к сельскохозяйственному машиностроению, в частности к устройствам для очистки и сортирования корнеклубнеплодов и фруктов.
