TRANSPLANTER KEEPING CONTROLLED HORIZONTAL STATE

摘要

PROBLEM TO BE SOLVED: To solve the problem of slow action of horizontal state controlling work caused by the screw-feeding with a motor and a screw shaft for lifting and lowering the right and left rear wheels relative to each other. SOLUTION: A hydraulic pump 17 is used as the driving source, a hydraulic cylinder 21 is extended or contracted with the pump 17 using a selector valve 22 and the switching of the selector valve 22 is performed by the pendulum movement of a pendulum-type sensor 16.
