PUSHING SWEEP Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: pushing sweep has rear wall 1 with upper part 2, intermediate guiding part 3 and lower pickup part 4 and lower bar 5 made integral along operating tool width, rear lower bar 6 split along operating tool width and upper bar 7. Lower front bar 5 and upper bar 7 are connected by guides 3. Such construction of rear wall 1 imparts rigidity to operating tool. Carrier wheels 10 are positioned behind guiding members 3 of rear wall 1. It allows carrier wheels 10 to be prevented from clogging by picked mass and usage of specific preventive devices to be eliminated. EFFECT: increased effective volume of working chamber, improved uniformness of charging working chamber, reduced metal usage, increased efficiency of operating tool and enhanced reliability in operation. 2 cl, 4 dwg
