SPRING RAKE FOR AGRICULTURAL WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a spring rake for an agricultural working machine composed by arranging many rakes at prescribed intervals in the cross direction of the working machine at the backward of a pudding rotor and having a snapping force individually bending upward touch with foreign substances such as a stone or a straw culm in a cultivated soil. SOLUTION: This agricultural working machine is equipped with the spring rake 6 installed at the backside of a tractor through a three-point linkage so as to be capable of being gone up and down and composed by arranging the many rakes at the prescribed intervals in the cross direction of the working machine at the backward of the pudding rotor. In the spring rake 6, (1) a supporting frame 6a for installing a base part of the each rake 6b is fixed to the working machine 3 and the each rake 6b installed to the supporting frame 6a has the snapping force individually bending upward when touching with the foreign substances such as the stone A or the straw culm B in the cultivated soil. (2) A ring part 6c for making the rake 6b easy to elastically move in the vertical direction are formed at the midpoint of the rake 6b.
