2. Description of the Related Art Conventionally, as this type of ridge coating machine, for example, as disclosed in Japanese Patent Laid-Open No. 6-22604, a plowing claw for embedding a ridge forming part (old ridge) in a machine frame. A rotator having a rotator is rotatably provided, and a rotary tool that is located at the rear portion of the rotary and that forms a ridge by compacting the embankment of the ridge molding portion is rotatably provided on the machine frame. As shown in FIG. 1, there is known a configuration including a rotating body forming an upper surface of a ridge, and an inner rotating plate and an outer rotating plate forming inner and outer side surfaces of the ridge at both ends of the rotating body. Further, as shown in FIG. 9, it is known that the rotating tool includes the rotating body and an inner rotating plate fixed to an inner end portion of the rotating body while omitting the outer plate.

[0003]

In the structure described in the above publication, the inner rotary plate and the outer rotary plate of the rotary tool shown in FIG. 1 and the inner rotary plate of the rotary tool shown in FIG. 9 are arranged in a direction orthogonal to the ridges. Since the inner rotary plate and the outer rotary plate or the inner rotary plate on one side can be applied to the side surface of the old ridge with the inner rotary plate and the outer rotary plate, even if the mud can be applied to the side surface of the old ridge. The mud that is tightened while applying it to the part is weakly tightened, the cracks of the old ridge cannot be surely closed, the ridge easily collapses and water leaks easily, and it is difficult to repair and repair the ridge that can endure for a long time. There is a problem.

The present invention has been made in view of the above circumstances, and the mud that is tightened while applying the mud to the side surface of the old ridge has a strong tightening force and can reliably close the cracks of the old ridge. It is possible, the ridges are hard to collapse and water is hard to leak,

The cutting soil sequentially cut by each of the cutting claws is sequentially discharged as mud for ridge coating toward the ridge coating body.

[0008] Further, the mud for furrow coating supplied to the furrow coating body has a cylindrical upper surface coating portion of the furrow coating body and a conical side surface coating portion of the furrow coating body, and the old furrow top surface portion and the old furrow portion. The ridges are sequentially applied along the side surface of the ridge, and the mud is used to simultaneously repair the upper surface of the old ridge and the side surface of the old ridge at the same time, and the old ridge is sequentially arranged into a predetermined shape.

[0009] At this time, the side coating portion of the ridge coating body is inclined so that the front side in the traveling direction is wider than the rear side with respect to the side surface portion of the old ridge, and the ridge coating body is output by the driving means. By being driven to rotate, the upper surface coating portion and the side surface coating portion of the ridge coating body are advanced while slip-rotating with respect to the mud, and the front side of the side surface coating portion of the ridge coating body and the side surface portion of the old ridge. A large amount of mud for supplying ridges is supplied from the mud supply rotary to the wide spread slope between the slopes. At the rear side of the narrowed side coating part, mud is applied to the side part of the old ridge with a strong tightening force.

Therefore, the cracks of the old ridges are surely closed by the mud, and the ridges after the ridges are applied are easily collapsed and the water is not leaked.

In the ridge coating machine according to the second aspect of the present invention, the mud-supplying rotary has a rotary shaft that is rotatably mounted on the machine frame with the old ridge side inclined at a low angle and has a short turning radius for cutting the side portion of the old ridge. The cutting claws and the cutting claws with a long radius of gyration for cutting the edges of the old ridges are radially projected, so that the short cutting claws and the long cutting claws of this mud supply rotary allow the side and the old ridges of the old ridges. The soil on the ridges is surely cut, and these cutting soils are sufficiently supplied to the ridge-coated body as mud soil for ridge coating.
