23, it is fitted into the engaging hole 7 of the fixed frame 8.

Accordingly, the rotating frame 97 having the ridge body 98 is fixed to the fixed frame 8 of the ridge coating machine main body 1 in a state of extending rearward. In other words, the rotating frame 97 having the ridge coating body 98 is positioned at a substantially middle portion of the ridge coating machine main body 1 without being shifted to the right side or the left side with respect to the traveling direction of the ridge coating machine main body 1, and maintains the weight balance. In this state, it is fixed to the fixed frame 8 of the ridge coating machine main body 1.

Since the main body 1 is maintained in a weight balance as a whole, it can be moved in a stable state without a risk of overturning during non-working such as running on a road.

The operation of raising the fixing pin 133 of the fixing means 122 is not limited to the case where the fixing pin 133 is brought into contact with one side of the fixing frame 8 of the ridge coating machine main body 1 and then the raising operation is performed. After the fixing of the fixing pin 108 of the moving arm 100 is released, the fixing pin 133 of the fixing means 122 is pulled up, and the fixing pin 133 is retracted into the guide hole 123 of the fixing pipe 124. The moving frame 97 may be rotated toward the rear of the ridger main body 1.

In the above embodiment, the depth adjusting means 76 is provided on the support provided on the left and right portions of the ridger main body 1.
Although the case where the rotary 55 is detachably attached to one of the selected ones of the 11 according to the installation direction of the transmission case 53 having the lower end at the lower end has been described, but the present invention is not limited to this, May be attached to the left and right support members 11 provided on the left and right sides, respectively.

Further, in the above embodiment, the rotary
The case in which the transmission case 53 having the lower end 55 and the rotating frame 97 having the ridged body 98 rotate in the left-right direction by manual operation has been described. However, the present invention is not limited to this. Case 53 and ridged body 98
May be rotated in the left-right direction by rotating operation means such as mechanical means.

In the above embodiment, the depth adjusting means 76 is attached to one of the supports 11 of the ridge coating machine main body 1.
The depth adjusting means 76 supports a transmission case 53 having a rotary 55 provided rotatably in the left-right direction with respect to the traveling direction of the ridge coating machine main body 1 about the input shaft 26 so as to be vertically movable. Although the depth adjustment has been described, the depth adjustment means 76 is not limited to this, and the rotary 55 is disposed on the right side or the left side with respect to the traveling direction of the ridge coating machine main body 1. The rotary 55 may be adjusted in depth by supporting a transmission case 53 provided so as to be able to move up and down around the center. That is, depth adjustment means
The depth of the rotary 55 may be adjusted by supporting the transmission case 53 which is not divided in the left-right direction with respect to the traveling direction of the ridge coater main body 1. In this case, the ridge body 98 is disposed behind the rotary 55.

[0125]

According to the first aspect of the present invention, since the transmission case is supported on the main body of the ridge coating machine so as to be vertically movable and the depth of the rotary provided on the transmission case is adjusted, the depth is adjusted. After setting the working position of the body to a predetermined position, the depth of the rotary can be easily adjusted independently of the ridge body by the depth adjustment means, and the old ridge is specified by each cutting blade of this rotary. It is possible to reliably supply a sufficient amount of mud on the old ridge to restore it to the height of
These mud soils are sequentially applied to the old ridges by the ridge application body, and the old ridges can be surely restored to a predetermined height and the ridges can be arranged.

According to the second aspect of the present invention, in addition to the effect of the first aspect, when adjusting the depth of the rotary, the operation handle of the depth adjustment means is rotated to operate the adjustment screw of the operation handle. Is rotated, and the adjusting support rod is moved up and down along the adjusting screw via the female screw portion screwed into the male screw portion of the adjusting screw, and the transmission case is moved up and down by the adjusting support rod. The rotary provided in this transmission case can be easily adjusted in depth. The cutting blades of this rotary supply a sufficient amount of mud to the old ridge to restore the old ridge to a predetermined height. The rotary can be adjusted and set to any possible position.

The female thread of the adjusting rod is screwed into the male thread of the adjusting screw, and the adjusting rod is moved up and down along the adjusting screw by the rotation of the adjusting screw. Adjustment makes it possible to easily fine-tune the working depth of cutting the soil of the rotary via the adjusting support rod and the transmission case.

According to the third aspect of the present invention, in addition to the effects of the second aspect, the main body of the depth adjusting means covers the outer peripheral portion of the adjusting rod and the adjusting rod screwed to the adjusting screw. By operating the depth adjusting means, it is possible to prevent a member or the like from being caught between the male screw portion and the female screw portion when the adjusting support rod moves up and down along the adjusting screw rod, and the adjustment can be performed along the adjusting screw rod. The rod can be moved up and down smoothly. Further, at the time of ridge coating work, the male screw portion of the adjusting screw can be prevented from being contaminated by mud by the cover body.

According to the invention of claim 4, in addition to the effect of the invention of claim 1, the input shaft of the transmission device is rotated by the output from the tractor that pulls the ridge coater body, and the input shaft is connected to the input shaft. The levee body can be driven and rotated by the output shaft that is linked to the rotation of the rotary and input shafts, so that each cutting blade of the rotary can reliably supply a predetermined amount of mud for levee application onto the old ridge, Slip the painted body and use this furrow painted body to firmly tighten the mud for furrowing supplied on the old furrow to the old furrow and apply it to restore the old furrow to a predetermined height so that it does not easily collapse. It can be neatly arranged.
