Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a rowing machine used for ridge creation, restoration work and the like.

[Conventional technology]

Conventionally, Japanese Unexamined Patent Publication No.
As disclosed in Japanese Utility Model Application Laid-Open No. 61-158105 and Japanese Patent Application Laid-Open No. 62-190002, a traveling machine is provided with a machine frame, and the machine frame is provided with a rotating rotor for laying up soil on an old ridge. It is known that a ridge body that can be tightened by vibration with a vibration generator at a position is provided.

[Problems to be solved by the invention]

However, in the case of the above conventional structure, when the ridge is tightened by the vibration of the ridge body, the shape of the old ridge or the shape of the ridge to be tightened due to the amount of embankment is uneven, and there is also a difference in the soil quality of the ridge at the position to be tightened. The ridge tightening reaction force received by the ridged body changes depending on the ridge tightening position, and this change in reaction force causes the vibration operation of the ridged body to be in an irregular state, which may result in insufficient ridge tightening. .

[Means for solving the problem]

The present invention is intended to solve these inconveniences, and its gist is to provide a machine frame on a traveling machine body, to provide a rotary rotor for raising soil on the old ridges, and to advance the rotary rotor. A ridged body having a shape matching the upper surface of the ridge and one side surface of the ridge is provided at a rear position in the direction, and a vibration mechanism for clamping and vibrating the ridged body is provided, and the ridged body is moved forward and backward toward the ridge. If possible, the ridged body is swept forward to prevent separation between the ridged body and the ridges and separation of the ridged surface and when the ridge tightening force is reduced. A ridge trimmer is characterized in that it is provided with a cushioning mechanism that causes a slow backward movement to cushion an excessive ridge tightening force when the ridge tightening force is excessively increased due to an excessive ridge tightening reaction force.

[Action]

The ridged body is provided so as to be able to move forward and backward toward the ridge, and the ridged body is separated from the ridged body by the cushioning mechanism and when the ridge tightening force is reduced, the ridged body and the ridged body are separated from each other. In order to prevent the separation of the ridge, the ridge body moves forward and moves backwards slowly to buffer the excessive ridge tightening force when the ridge tightening force is excessively increased due to the excessive ridge tightening reaction force applied to the ridge body. Will tighten the ridge while repeating this movement according to the ridge to be tightened.
