As described above, according to the first aspect of the present invention, the steering wheel is provided at the rear of the traveling body in the traveling direction, and the wheels are disposed on one side of the traveling body while traveling. Since the other side of the fuselage is provided with a rotary ridge that also serves as a soil-removing rotor and wheels, the size and weight of the machine can be reduced, and the machine can be easily transported. It is suitable for the levee work in the field, and the flexibility of use can be improved.

According to the second aspect of the present invention, a plurality of pressing surfaces are formed at intervals on the outer peripheral portion of the rotary ridge, and each of the pressing surfaces is pressed at a position forward in the rotation direction. The front part of the clamping plate, which extends from the surface side to the compression surface of the adjacent compression surface part at the rear position, is arranged, so that the rotation of the rotating ridge body in the direction that promotes the advance of the traveling body With this, the pressing plate body gradually tightens the embankment and is strongly tightened by the pressing surface portion through the pressing plate body. Due to the presence of the clamping surface,
The tightening pressure can be increased by reducing the tightening area compared to the structure where tightening is performed on the entire outer peripheral surface of the rotating ridge, and the ridge can be firmly tightened accordingly. By increasing the height, the pressing plate body of the rotating ridge body comes into slip rotation contact with the ridge surface, and the slip rotation contact enables the ridge surface to be smoothly and firmly tightened and ridged,
According to the third aspect of the present invention, the rotating ridge body comprises a side ridge portion on which one side surface of the ridge can be rotated and fixed, and an upper surface ridge portion on which the upper surface of the ridge can be rotated and fixed. The one side surface of the ridge and the upper surface of the ridge can be simultaneously rotated and leveled, and can be squeezed satisfactorily. In the invention according to claim 4, a through hole is provided between the pressed surface portions. Since the pressing plate body is formed of a flexible plate material at the same time, the ridge surface is more intermittently pressed by the through-hole, so that the pressing force can be firmly increased and the pressing force is increased by the flexibility. The plate body can flexibly compress the embankment while flexing, and can suppress the adhesion phenomenon of the soil to the outer peripheral portion of the rotating ridge.
The ridge corner between the upper surface and the one side surface of the ridge can be satisfactorily pressed, so that a good ridge work can be performed, and a more robust ridge can be obtained.
