A pressing plate G is disposed on the pressing surface portion K with bolts 26, and the pressing plate G is made of a synthetic resin plate such as a flexible nylon resin or a vinyl chloride resin. It is made of a material that can be bent in an arc shape by an external load and can be restored to a substantially flat shape by self-elasticity when the load is released. And other resin plate materials are also used, but with the rotation of the rotary ridges 17, the compression plate G gradually tightens the embankment and is strongly pressed by the compression surface portion K via the compression plate G. It is configured to tighten.

Since the first embodiment of the present invention has the above configuration, the traveling machine 1 travels along the old ridge and the power take-off shaft 9 is rotated, while the embankment mechanism 4 raises the field mud on the old ridge. The cover member 14 prevents the mud from scattering upward and to the side of the ridge, and the raised mud is prevented from scattering outward and falls by its own weight, and on the other hand, the power take-out shaft 9 of the traveling body 1 is used as a drive source to regulate the mud. The ridge mechanism 16 is driven to rotate the ridges 17.

Due to the presence of the plurality of pressing surfaces K, the pressure is intermittently tightened.
The tightening pressure can be increased by reducing the tightening pressure area as compared with the structure in which tightening is performed on the entire outer peripheral surface, so that the ridges can be firmly tightened. By increasing the rotation speed of the body 17, the pressing plate G of the rotary ridge body 17 comes into rotational sliding contact with the ridge surface, and the rotational sliding contact smoothly and firmly tightens both side surfaces W ₁ and W ₁ of the ridge W. The ridge can be pressure-aligned, and a more robust ridge can be obtained.

At this time, since the through holes F are formed between the adjacent pressing surfaces KK, the ridge surfaces are further intermittently pressed by the through holes F, so that the ridges are firmly strengthened. The rotary ridge 17 can be tightened and has the through holes F.

It is possible to perform good ridge work, and since the pressing plate G is formed of a flexible plate, the pressing plate G bends from the flat state and gradually presses the embankment while bending. Can be
The embankment can be securely clamped.

The second embodiment shown in FIG. 9 shows another example of the structure. In this case, a plurality of embankment blades 7b having different lengths are protruded from the outer periphery of the rotor shaft 7a.

In the second embodiment, the same operation and effect as in the first embodiment can be obtained.

The present invention is not limited to the above embodiment, but includes, for example, the embankment mechanism 4, the rotary ridge 17 and the ridge 16 and the number and shape of the pressing surface portion K and the through hole F. The size, material, and the like of the pressing plate body G are appropriately changed and designed.

[0019]

As described above, according to the first aspect of the present invention, when the traveling body travels along the old ridge, on the one hand, the embankment mechanism raises the field mud on the old ridge, and on the other hand, The ridge setting mechanism is driven, and the rotary ridge is rotated by the rotation mechanism, and the rotary ridge is pressed against both sides of the ridge to perform rotary ridge. Therefore, both sides of the ridge are firmly tightened. Can be pressed, and a good ridge can be obtained.

According to the second aspect of the present invention, a plurality of pressing surfaces are formed at intervals on the outer peripheral surface of the rotary ridge, and the pressing is performed at a position forward of the rotary ridge in the rotation direction. Since the pressing plate from the surface side to the pressing surface of the adjacent pressing surface at the rear position is arranged, the pressing plate gradually tightens the embankment with the rotation of the rotating ridge. It is strongly tightened by the tightening surface portion via the pressing plate body, is intermittently pressed by the presence of the plurality of pressing surface portions, and is entirely rotated by the presence of the plurality of pressing surface portions. The tightening pressure can be increased by reducing the tightening pressure area compared to the structure that tightens with the ridge, and the ridge can be tightened accordingly, and the rotation speed of the rotary ridge body against the running speed of the traveling machine By increasing the height, the pressing plate body of the rotating ridge body comes into sliding contact with the ridge surface, The two side surfaces of the ridge can be smoothly and firmly tightened by touch, and a more robust ridge can be obtained. In the invention according to claim 3, the adjacent pressing surface portion is Since a through hole is formed between the holes, the ridge surface is more intermittently pressed by the through hole, and the ridge surface can be tightened more strongly. In the invention according to the fourth aspect, the pressing plate body is formed of a flexible plate material. Therefore, the pressing plate body can gradually compress the embankment while flexing from the flat shape, and can surely press the embankment.

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