UNIT FOR DETACHING SOIL LUMPS FROM FRUITS Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: unit has a supporting surface inclined to the horizon and in the plane positioned lengthwise along its sense of movement. A dividing arrangement is placed above the upper generatrix of the surface in a spaced relationship to it. The arrangement straddles the supporting surface which is rod-shaped. The arrangement is composed of rolling channeled members placed in series and in parallel relative to each other. The surface members are urged by a drive to rotation in a direction opposite to that of the supporting surface drive shaft. The dividing arrangement is inferior to the supporting surface in linear velocity. The members of the arrangement are placed so as to contact with driving means having the form of friction slides mounted above the supporting surface in a spaced relationship to its upper generatrix and above the dividing arrangements in the region of the supporting-surface lower generatrix. The unit is also provided with a device for discharge of separating fractions. EFFECT: increased technological possibilities. 4 cl, 5 dwg
