Since this embodiment has the above configuration,
As shown in FIGS. 1 to 8, the mounting member 7 is moved in one side direction with respect to the traveling direction by the moving mechanism 8, and the main levee mechanism 28 is moved.
When the traveling body 1 travels along the old ridge and the power take-off shaft 16 is rotated, the main embankment mechanism 3 is positioned.
The embankment rotor 35 of No. 0 continuously jumps up the field mud on the ridge onto the old ridge and raises it.
5 prevent the mud from scattering upwards and to the side of the ridge, and the splashed mud is prevented from scattering outward and falls by its own weight.

In this case, since the through holes F and C are formed between the pressing surfaces K and D and the pressing plates GE are formed of a flexible plate material, the through holes F and C are formed. C makes it possible to more intermittently press the ridge surface, so that it is possible to tighten more firmly, and the flexibility allows the pressing plate bodies G and E to flexibly compress the embankment while flexing. deposition phenomenon of soil to the outer peripheral portion of the rotary Seiaze body 13 can be suppressed, it can be pressed satisfactorily tighten the ridge corners of the upper surface W ₁ of the ridge on the other hand with the side surface W _2, good Seiaze work Can do
More robust ridges can be obtained.

Therefore, even if the mounting member 7 is moved in the lateral direction by the moving mechanism 8, the power from the power source of the traveling body 1 to the ridge body 9 can be smoothly transmitted and the structure is simplified. be able to.

In this case, the old ridge surface can be previously shaved by the shaving mechanism 56, and the main embankment mechanism 3 is placed on the shaved ridge surface.
0, the embankment is filled, so that the binding property between the old ridge and the embankment can be enhanced, and a firm ridge can be obtained accordingly. Since the ridge 33 is provided detachably, the main ridge mechanism 28
When performing the ridge work, the sub-rotation ridge body 33 can be removed, and the main rotation ridge body 31 can perform the ridge work better.
