CROP LIFTER FOR LIFTING STALKS AND BRINGING THEM TO CUTTERBAR Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: to promote reliability of device and reduce harvest losses the crop lifter has fingers 1 articulated on endless traction member, driving 3 and driven 4 pulleys, and guide members 5 and 6. The latter are installed around the outline of traction member at an angle to each other so as to ensure turning of fingers in working zone in the plane perpendicular to direction of movement of traction member. Said member has the form of cable 2 with stationary bushings installed on it at a certain pitch. Fingers are installed on said bushings 7 with a provision for turning around an axis coinciding with cable axis. Driving 3 and driven 4 pulleys have mating bushings 7 with hollows 9 over outside diameter, whose pitch corresponds to that of bushings on cable 2. Fingers are of an L-shaped configuration , made of steel and their smaller leg is articulated on bushings 7 by means of intermediate bushings 8. EFFECT: improved design. 7 dwg
