Since this embodiment is constructed as described above, when the power take-off shaft 6 is rotated while the tractor 1 is traveling along the old ridge, the rotary rotor 5 as the embankment mechanism 4 raises the field mud on the ridge to the old ridge. The cover member 10 and the side cover member 11 prevent the mud from scattering above and to the side of the ridge of the rotary rotor 5, and the mud that is lifted up is prevented from scattering outside.

Since the forced rotation is carried out by No. 6, it becomes possible to perform a smoother smooth grading process, and it is possible to perform a good grading work. In this case, the earth removing mechanism 28 is used to grind the upper surface of the old ridge. Since the soil can be formed and the embankment mechanism 4 embeds the soil on the excavated ridge surface, it is possible to enhance the binding property between the old ridge and the embankment, and to obtain a stronger ridge.

Further, in this case, since the annular protrusion 13b which can be fitted into the ridge upper surface W ₁ is formed on the substantially cylindrical outer peripheral surface 13a of the ridged body 12, lateral deflection of the ridged body 12 can be prevented.

In the above-mentioned embodiment, the ridge-arranging mechanism has a structure in which the ridged body is operated to reciprocate the ridges, but it can be applied to a structure in which the ridges are simply rolled with a structure that does not hit the ridges at all, and a reciprocating ridge-striking operation is also performed. Instead of this, it can be applied to a structure in which the ridged body is vibrated by a vibrating mechanism and the ridges are tightened by the vibration.

The ridged body of the above-mentioned embodiment is formed in the shape of a horizontally rotating roll having the rotation axis line in the horizontal direction, but the rotation axis line is arranged in the vertical or slightly oblique vertical direction. It is also possible to use a ridged body formed in the shape of a vertically rotating roll having a line segment that fits the upper surface and one of the ridges as a bus.

Further, in the above embodiment, the ridge body 12 and the earth cutting rotor 32 are rotated by the hydraulic motor, but they can be rotated by the main shaft 7 of the tractor 1 via a mechanical transmission mechanism. On the contrary, a structure in which the rotary rotor 5 is rotated by a hydraulic motor may be adopted.

[0024]

As described above, according to the present invention, when the tractor runs along the old ridge, the embankment mechanism raises the field mud on the ridge while the cover member and the side cover members prevent the mud from scattering. Then the soil piled up on the old ridge will be tightened by the rolling of the rotary ridge-shaped ridge body, so that the ridge body can be smoothly smoothed and the ridge surface finish is improved, and Since the rear end of the side cover member in the advancing direction is disposed close to the outer peripheral surface of the rotary roll-shaped ridge body, the rear end portion of the side cover member in the advancing direction and the outer peripheral surface of the ridge body are disposed. The gap can be made as small as possible, the scattering of soil from the gap can be prevented, the embankment efficiency can be improved, and good leveling work can be performed.

Further, at this time, by forcibly rotating the rectifying body by the rotating mechanism, it becomes possible to perform a smoother grading process which is more favorable and smooth, and it is possible to perform a good grading work. By excavating the upper surface of the old ridge, the embankment mechanism will be used to embed it on the excavated ridge surface, and the bond between the old ridge and the embankment can be enhanced, and the ridge that is strong Can be obtained.

As described above, the intended purpose can be sufficiently achieved.
