However, in the above-mentioned conventional structure, since the machine frame is arranged in a projecting state from the traveling machine body through the connecting mechanism, the machine frame receives its own weight and the traveling posture of the machine frame depending on the field scene. In order to stably hold and enable stable running, a stabilizing member may be provided on the machine frame side, but that stabilizing member is simply fixed to the machine frame side and attached, and the ridge tightening reaction force is When applied, the reaction force causes the machine frame to be lifted due to the existence of a connection gap between the connection mechanism and the twisting of the connection mechanism, etc. By this lifting, the stabilizing member floats up from the field scene and stabilizes when the reaction force is no longer applied. The machine frame descends under its own weight until the members come into contact with the field scene, which causes the machine frame to repeatedly lift and lower, which causes the machine frame to rattle and vibrate, which causes the traveling machine body to vibrate. Or discomfort to raised to the power of the worker,
Stable running is hindered, and when the stabilizing member floats, it may not be possible to receive the arranging reaction force due to the grounding resistance, so that it may not be possible to perform a satisfactory arranging work.

Since this embodiment has the above structure,
When the traveling machine body 1 is run along the old ridge and the power take-off shaft 6 is rotated, on the other hand, the rotating rotor as the embankment body 5 continuously flips up the field mud on the edge of the ridge to the old ridge and raises the cover member 10. Preventing the mud from scattering above the embankment 5 and to the side of the ridge, the splashed mud is prevented from scattering outside and falls by its own weight, while the soil that has been mound on the old ridge of the traveling body 1 is prevented.

Is driven by the two ridges 11 and 12 on the front side and the rear side, which are shaped to fit the upper surface of the ridge W and one side surface of the ridge, and are squeezed by the reciprocating ridge striking operation to perform the rectifying work. Become.

At this time, when the ridge tightening reaction force is applied to the machine frame 3 side by the arranging operation of the ridge adjusting bodies 11 and 12, and the stabilizing member 30 rises, the damper 32 is caused by the weight of the stabilizing member 30 and the outer cylinder body 36. When the piston rod 39 of No. 1 rapidly projects, that is, when the distance between the upper connecting pin 53 and the lower connecting pin 54 is extended, the hydraulic oil O in the upper portion of the inner cylindrical body 36 is located inside the upper communicating hole 41. The hydraulic oil O flows out between the tubular body 37 and the outer tubular body 36, enters the base tubular body 42 through the lower communication hole 44, the valve body 48 is lifted against the compression spring 52, and the valve hole 49.

The hydraulic oil O between the outer cylinder body 36 and the inner cylinder body 37 is supplied to the upper communication hole 4
1 and returns to the inside of the inner cylinder 37, and the damper 32 accompanies the gradual contraction resistance operation and the quick extension operation at the time of compression, and the rattle on the machine frame 3 side due to the ridge tightening reaction force repeatedly applied to the machine frame 3 side. It is possible to suppress the vibration phenomenon due to vibration and to receive the ridge tightening reaction force due to the ground resistance of the stabilizing member 30 against the field scene M. In particular, at this time, the spring member 5 which can press the piston rod 39 in the protruding direction to the damper 32.
6 is arranged, the valve hole 50 is quickly closed by the valve body 50 by absorbing the axial gap existing between the lower lid 46 of the damper 32 and the lower connecting pin 54, and the piston rod 39 The resistance to contraction can be quickly given, the responsiveness of the projecting motion of the piston rod 39 can be made sensitive, and the responsiveness of the damper 32 can be enhanced, and thus the rattling vibration phenomenon can be further suppressed. It is possible and can perform good arranging work.

Further, in this case, since the adjusting mechanism 57 capable of variably adjusting the elastic force of the spring member 56 is provided, the spring member 5 is adapted in accordance with the hardness, softness, coarseness and denseness of the ridge or the embankment state.
6 can be adjusted, and a state without the spring member 56 can be obtained. By adjusting the elastic force of the spring member 56 according to the adjustment condition, the force on the machine frame 3 side can be adjusted. The rattling vibration phenomenon can be further suppressed, and in this case, since a hydraulic damper is used as the damper 32, the structure can be simplified and the manufacturing cost can be reduced, and the stabilizing member 30 can be provided.

Can be obtained.

In addition, at this time, the stabilizing member 30 swings up and down and up and down in accordance with the field scene M by the vertical movement mechanism 31, and the stabilizing member 30 is stably grounded to the field scene M. The ridge tightening reaction force applied to the ridge 30 can be reliably received, and even when the machine frame 3 is vertically adjusted by the connecting mechanism 2 in accordance with the height of the ridge to be constructed and restored, the stabilizing member 30 keeps the field. It can move up and down so as to be in contact with the surface M, and good ridge work can be obtained, and accordingly, a strong ridge can be obtained.

Further, in this case, as the vertical movement mechanism 31, a guide shaft 34 is laterally provided on the machine frame 3 side, and a guide elongated hole slidably fitted to the guide shaft 34 on the front side in the traveling direction of the stabilizing member 30. 35, the stabilizing member 3 is formed.
0 can move vertically and vertically by slidingly fitting the guide shaft 34 and the guide elongated hole 35, so that a stable grounding state can be obtained, and a good leveling work can be obtained.

The present invention is not limited to the above-mentioned embodiment, and for example, as the embankment mechanism 4, a rotary rotor having a rotation axis line in a direction intersecting with the ridge forming direction may be adopted. Further, although the two ridges are provided in the above-described embodiment, it can be applied to a structure in which one ridge is used for arranging, and as the structure of the arranging mechanism, the ridge is hit using a hydraulic mechanism. It can also be applied to structures, vibrator structures, unbalanced rotation structures using eccentric weights, and other types of vibration mechanisms that tighten ridges, and as the damper 32,
A structure that uses a buffer spring or a structure that uses both oil pressure and gas,
It is also possible to employ a structure that uses both hydraulic pressure and air.

[0024]

As described above, according to the present invention, when the traveling body is driven along the old ridge, the embankment mechanism raises the mud on the old ridge, and the ridge mechanism adjusts the upper surface and one side surface of the ridge. At this time, when the ridge tightening action causes the ridge tightening reaction force to be applied to the machine frame side and the stabilizing member rises, the piston rod of the damper quickly expands, and on the other hand, when the ridge tightening reaction force is no longer applied, the piston The rod will immerse with resistance, and the rattling vibration phenomenon on the machine frame side due to the ridge tightening reaction force repeatedly applied to the machine frame side by the damper accompanied by the gradual contraction resistance operation and quick extension operation during compression. Can be suppressed, and in particular, the damper is provided with a spring member capable of elastically pressing the piston rod in the protruding direction,
