ROOT HARVESTING COMBINE Russian patent published in 2000 - IPC

FIELD: agricultural engineering. SUBSTANCE: combine has frame carrying mellowing-digging bracket for each row of roots, picking bracket, cleaning devices, activator chamber filled with water and equipped with automatic water supplying valve for supplying water from reserve tank, sewage water pump, hydraulic cyclone with feeding branch pipe, clear water drain branch pipe, sludge branch pipe dipped into sediment, chute, and charging working tools. Combine is further provided with digging-cleaning module for each row of roots. This module is fixed on frame for repositioning in accordance with width of spacing, and has feeding detachable drum with blades, each having row of conical rubber fingers. Digging share with mellowing tillage bracket is mounted for rotation in detachable casing of module. Digging share has sides and bracket adapted for picking up roots and narrowing roots flow and equipped with separating fingers and cylindrical separating brushes mounted for free rotation and provided with corrugated rubberized surface and root guide. The latter is leading to gathering auger with inclined chute coupled to separating chamber which has intake grid for sewage water pump communicated via feeding branch pipe with hydraulic cyclone. Hydraulic cyclone has clear water drain pipe and sludge branch pipe provided with disk-shaped bottom with opening in the center of chamber and annular perimeter opening. Sludge branch pipe is attached above sediment hopper equipped with retaining shutter. Activator disposed in chamber is made in the form of disk with lower blades which are curved so as to move roots to chamber center and to vertical auger. Combine is further provided with annular nozzle for discharging clear water from hydraulic cyclone and slit-type nozzle for supplying compressed air from high-pressure fan. EFFECT: increased efficiency and simplified construction. 2 cl, 5 dwg
