CABBAGE-HARVESTING MACHINE Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: machine has a frame with guide elevators 1 mounted on it. Chain conveyer 2 and a clamping conveyer with a pair of chain circuits 4 are located behind the elevators. Circuits 4 are interconnected by cross flexible links made in the form of springs 5 under which guides 6 are positioned in parallel to their inclined part and the lower branch of the clamping conveyer. Longitudinal plates 9 are mounted under the lower branch of the clamping conveyer. The distance between the inner sides of the plates is equal or larger than the distance between horizontal parts of guides 6. Moreover, cable 13 is mounted inside each spring 5 of the flexible links, the cable length is smaller than the length of spring 5 in an extended position. The ends of cable 13 are fastened to the circuits at the point of fastening springs 5, and sprockets 3 of lower branches are spring-loaded relative to the frame. EFFECT: improved structure. 4 dwg
