The connecting body 2 is connected to the middle eccentric portion 18b-19b via bearings 20 and 21.
2. Bear the device rotatably, insert this connecting body 22.n in a slidable manner, and attach the shaft end 18a.1 of the eccentric shaft 19.
9 Fix sprocket U to a, and
The chain 6 is suspended between them, and the upper eccentric shaft is rotatably provided by the power shaft 8 via the universal joint, telescopic shaft n, and gears 28-29, and the buffer material 30 is attached to the lower coupling body. A mounting bracket 81 is attached via bolts 32.

The wing is a ridged body, and is formed in a vertical cross-sectional shape that matches the top surface of the ridge and one side of the ridge, and the ridged body is attached to the mounting bracket 81 so as to be vertically adjustable through the bolt U1 selection hole.

The elision is a slurry body, and rubber, sponge, fur, resin, etc. are used, and this slurry body may be omitted, or a material with good slippage may be attached to the surface of the ridge adjustment body. .

The nail is a wheel that can move up and down, and is used to support the machine frame 3.

Since this first embodiment has the above configuration, when the traveling body 1 travels along the old ridge 4 and the power take-off shaft 6 is rotated, the rotating rotor 5 continuously crushes the field soil onto the old ridge 4. By heaping up the area and removing the cover part, mud is prevented from scattering above the rotating rotor 5 and to the sides of the ridge, and on the other hand, the ridge tightening mechanism 1
3, the upper surface of the ridge 4 and one side of the ridge are sandwiched between the ridge trimmers having a vertical cross section, and the ridges are tightened to perform the ridge trimming work. Tighten,
In other words, in this case, the ridge adjustment device performs a circular motion with a radius of eccentricity ε shown in FIG. In order to tighten the ridges by moving with a trajectory R, the ridge adjustment body (
Even if the height of the embankment in front is high, the ridge can be tightened by reliably and smoothly, and the sliding action against the ridge suppresses the adhesion of mud to the ridge adjustment device, and the finished state of the ridge surface is good. Furthermore, the operation speed can be improved by smoothing the movement of the ridge adjustment device through the circular locus motion, making it possible to obtain robust ridges and increasing the working speed.

The second embodiment shown in FIG. 6 shows another example of a support structure with a ridge tightening mechanism.
