RIDGE-PUSHING PLATE UNIT IN RIDGE-FORMING MACHINE

摘要

PROBLEM TO BE SOLVED: To achieve a beautiful ridge form having a firm solidity in a compacting type ridge-forming machine performing the formation of the ridge by using a ridge-pushing plate. SOLUTION: This ridge-pushing plate unit in the compacting type high ridge- forming machine 1 joining the ridge-pushing plates 4 at the both ends of shafts for transmitting an output from an engine 2 of the ridge-forming machine body in left and right directions through crank mechanisms 3 is characterized by constituting the ridge-pushing plate 4 so as to keep a prescribed angleαformed by a ridge surface-rubbing resin plate 6 against a beating iron plate 5 by installing an elastic member 7 in a narrow angle space S formed by adhering only the base ends of the inside beating iron plate 5 and an outside ridge surface-rubbing resin plate 6 each other, compressing the elastic member 7 on compacting for beating the ridge surface powerfully by a large pressure stress of the beating iron plate 5 and the ridge surface-rubbing resin plate 6, and on returning, rubbing collapsing soil from the upper part of the ridge by the ridge surface-rubbing iron plate 6 by a returning force of the elastic member 7 while leaving the beating iron plate 5 from the ridge surface so as to finish the ridge surface.
