HAY-MAKING IMPLEMENT Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: implement has brackets 34 and 35 for mounting on a power unit, carrier wheels 27, shoe soles 25 mounted to be above the support plane of wheels 27, side walls and back wall 1. Lower part 3 and upper part 2 of the wall consist of picking and guiding members. The front ends of the latter are in one vertical plane with axles 30 of carrier wheels 27. The lower part of walls 4 is mounted at an angle less than the angle of material friction against the member surface, and the side walls are hinged to the truss of back wall 1 for folding. The members of side and back walls are arches with their upper parts 2 bent in the direction of the implement motion, and the side ones are bent towards inside the implement chamber. The guiding arch in the center of back wall 1 is mounted to follow the axial line of wall 1, and left and right of it there are guiding members arranged with gradual decrease in the angle of their tilt towards the side walls. The side walls are positioned at an angle relative to back wall 1. The side wall members are arches arranged with gradual decrease in the angle of their tilt towards back wall 1. EFFECT: higher quality of picking; higher performance. 4 cl, 7 dwg
