The invention relates to agricultural machin-building, in particular to working elements of potato harvesting machines. A drive hollow cone, mounted vertically, from above has a narrow cylindrical part, inside which on a drive cantilevered shaft a vertical screw conveyer is arranged, from below of which a distributor as a solid cone with fixed rows of short fingers is fixed. The internal surface of the hollow cone above the divider comprises elastic fingers shaped as a trapezoid, and thereunder an additional driving hollow cone is arranged, the vertex of which is directed upwards, and it is made as round concentrical rods fixed with gaps. The technical result is in improving the quality of cleaning the tuberous roots from dirt by 20...25%. |
