BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furrowing machine and, more particularly, to a furrowing machine for repairing an old furrow which divides a paddy field to prevent water leakage.

[0002]

2. Description of the Related Art Conventionally, as this kind of ridge coater, for example, as described in Japanese Patent Application Laid-Open No. Hei 6-22604, a rotary having a tilling claw that fills a ridge forming portion (old ridge) is used. Is rotatably provided at a rear portion of the rotary, and a rotatable tool for solidifying the embankment of the ridge forming portion to form a ridge is provided rotatably.
As shown in the figure, an inner rotating plate and an outer rotating plate having a cylindrical rotating body forming an upper surface of a ridge on a horizontal rotating shaft and conical surfaces forming inner and outer surfaces of the ridge at both ends of the rotating body are fixed. The configuration is known. Further, as shown in FIG. 9, the rotating tool has an outer rotating plate omitted from the horizontal rotating shaft and an inner rotating plate having a conical surface fixed to the inner end of the rotating body and the rotating body. Is known.

[0003]

In the configuration described in the above publication, a rotating plate having a conical surface and a rotating body are fixed to a horizontal rotating shaft, and since the rotating body is cylindrical, the rotating body is formed at the time of ridge formation.

At 42, the mud is painted while being pressed against the upper shoulder side and the opposite side of the old ridge A.

Accordingly, the upper and lower portions of the side portion B of the old ridge A and both side portions of the upper portion C of the old ridge A are firmly compacted and repaired sequentially, and the ridge after the ridge application is fully compacted as a whole. The ridges are smoothed and smoothed, and the surface of the ridges after the application of the ridges are finished neatly and have a good appearance, and the ridges are laid without easily collapsed or leaked.

Further, in each of the above-described embodiments, the ridge coating body 31 having the side restoration body 32 and the upper surface restoration body 34 is eccentrically rotated at a predetermined traveling speed and a predetermined amplitude, so that the side restoration body 32 is formed. The surface of the side B of the old ridge A to be repaired and repaired is smooth and orderly as a whole, and the surface of the upper C of the old ridge A repaired by the upper surface restoration body 34 is smooth and orderly as a whole. It is tied.

In each of the above embodiments, the case where the shaft support 35 is connected to the connecting plate 40 of the side restoration body 32 has been described. However, the present invention is not limited to this. Board
45 may be removably connected by the same means as in the above embodiments. Further, the shaft support 35 may penetrate the connection plate 40 of the side restoration body 32 and the connection plate 45 of the top restoration body 34 to be detachably connected. The side restoration body 32 and the top restoration body 34 may be provided with reinforcing members inside each of them so as to reinforce them so that they can sufficiently withstand the earth pressure. The body 48 may be supported.

According to the first aspect of the present invention, the ridge-coated body has a conical side restoration body for restoring the side of the old ridge to an inclined surface which is expanded downward and a diameter reduction of the side restoration body. It has a conical top restoration that is connected to the end and restores the upper part of the old ridge to a horizontal surface, so the mud when the side of the old ridge is restored with the side restoration is reduced by the shrinkage of the side restoration. In addition to being able to push up towards the shoulder of the old ridge on the radial side, mud when repairing the upper part of the old ridge with the upper restoration can be guided toward the shoulder of the old ridge on the reduced diameter side of the upper restoration. These muds can be sequentially applied to the shoulders of the old ridge at the reduced diameter ends where the side restoration body and the top restoration body are connected to each other, and the shoulder of the old ridge can be firmly compacted.

Further, since the ridge-coated body is eccentrically rotated by the rotating shaft supported on the shaft support at the eccentric position of the ridge-coated body, the side restoration body and the upper-side restoration body of this ridge-coated body are respectively replaced with the old ridge. Can be eccentrically rotated so as to make a wave against the side of the old ridge and the upper part of the old ridge. For this reason, the mud is applied while being strongly pressed against the side of the old ridge by the side restoration body, Mud is applied while being strongly pressed against the upper part of the old ridge by the upper restoration.

Therefore, as a whole, the shoulders as well as the sides and the upper part of the old ridge can be sufficiently firmly repaired, and the ridge after the ridge application as a whole is sufficiently tied to prevent collapse. The surface portion of the ridge is finished in order and has a good appearance, and it is possible to provide a ridge coating machine which can repair a ridge which can withstand a long term without easily collapsing or leaking water.

According to the second aspect of the present invention, since the shoulder restoration portion is provided between the side restoration member and the upper restoration member to restore the shoulder of the old ridge to the inclined surface, the shoulder restoration portion is provided. Mud is applied to the shoulder of the old ridge in order, and the shoulder of the old ridge can be firmly fixed on the inclined surface to be repaired, and the ridge can be prevented from easily breaking down from the shoulder of the inclined surface.

According to the third aspect of the present invention, the side restoration body and the top restoration body each have a connecting plate detachably connected to each other with their reduced diameter ends joined together, and one of the connecting plates is provided. Since the axial support is connected to the eccentric position of the above, by supporting the rotation shaft with this support, the ridge coating body can be easily fixed to the rotation shaft by the shaft. The ridged body can be eccentrically rotated about the axis,
The side restoration body and the top restoration body can easily be replaced by replacement when one of them is disturbed in the mud painting repair work such as when one of them is worn or damaged.
