The structures shown in Japanese Patent No. 605 and Japanese Utility Model Laid-Open No. 5-60207 are known.

In these conventional structures, a rotating machine is connected to a traveling machine body by a connecting mechanism so that the machine frame can be moved up and down, and a rotary rotor for bouncing the soil on an old ridge as an embankment mechanism has its rotation axis line. Provided in the direction parallel to or intersecting the construction direction,
A cover member is provided on the machine frame above the rotating rotor and above the ridges, and a rectifying body having a shape matching the upper surface of the ridge and one side surface of the ridges is provided at a rear position in the traveling direction of the rotating rotor, and the power of the traveling machine body is provided. A crank type or hydraulic type ridge striking mechanism that reciprocally drives the ridged ridges by using the take-out shaft as a drive source is provided. The embankment is constructed so as to be struck by the ridge striking motion of the rectifying body.

In another conventional structure, a vibration mechanism for vibrating the ridge body by using the power take-out shaft of the traveling machine body as a drive source is provided as the ridge mechanism, and the embankment is raised on the old ridge. Is configured to be tightened by the vibration motion of the ridge body.

[0005]

However, in the case of the above-mentioned conventional structure, although the stabilizing member for receiving the ridge fastening reaction force is provided on the machine frame side, the stabilizing member is simply fixed to the machine frame side. When the ridge tightening reaction force is applied, the reaction force is directly transmitted to the machine frame side, which causes a strong vibration of the machine frame side, and this vibration causes discomfort to the operator on the traveling machine body. In some cases, stable running may be hindered, or the ridge tightening may be incomplete, making it impossible to perform good ridge trimming work.

In view of the above, a structure having a cushioning mechanism capable of cushioning the ridge tightening reaction force applied to the above-mentioned stabilizing member has been proposed as disclosed in Japanese Patent Laid-Open No. 63-248303 by the present applicant. However, since this stabilizer is simply provided so that it can move up and down, it only moves straight up and down in accordance with the unevenness of the field scene. In some cases, it may not be possible to receive the clamping force well, and there may be partial contact between the stable member and the field, which may force the stable member and its support mechanism to be damaged, impair stable driving, or even cause ridges. There is a problem in that the tightening may be incomplete and good trimming work may not be performed.

[0007]

Since this embodiment has the above-mentioned structure, when the traveling machine body 1 is run along the old ridges and the power take-off shaft 6 is rotated, the rotary rotor as the embankment body 5 raises the field mud on the ridges to the old ridges. The cover member 1
0 prevents 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,

By the reciprocating ridge striking operation of the two rear side rectifying bodies 11 and 12, the rectifying work is performed by being struck and tightened.

At this time, by the arranging operation of the ridge adjusting bodies 11 and 12, a ridge tightening reaction force is applied to the machine frame 3 side to raise the stabilizing member 30, and the distance between the upper connecting pin 53 and the lower connecting pin 54 is increased.
