Is configured. It should be noted that the base trimming rotator 36 may be forcibly rotated by obtaining a power source.

Since this embodiment is constructed as described above, when the power take-off shaft 6 is rotated while the tractor 1 is traveling along the old ridge, the rotary rotor 5 as the embankment mechanism 4 raises the field mud on the ridge to the old ridge. The cover member 10 and the side cover member 11 prevent the mud from scattering above and to the side of the ridge of the rotary rotor 5, and the mud that is lifted up is prevented from scattering outside. On the other hand, the soil that has fallen by its own weight, and on the other hand, the soil piled up on the old ridge is clamped and adjusted by the ridge body 12 rotated by the rotating mechanism 19, and then the ridge upper surface W ₁ and the ridge one slope W ₂ are ridged by the ridge hitting mechanism 22.

Further, in this case, the base W ₃ of the ridge W is clamped by the base ridge-rotating body 36 which is formed in a conical roll shape and has a substantially conical outer peripheral surface 36a which fits one slope W ₂ of the ridge W. Since it is configured as described above, the ridge base W ₃ can be firmly tightened, and the ridged body 12 can be prevented from lateral vibration by receiving the ridge-arranging reaction force due to the penetration of the penetration convex portion 36c. , So that it can get good arranging work.

The present invention is not limited to the above-mentioned embodiment, and for example, as the embankment mechanism 4, a rotary rotor having a rotation axis line in a direction intersecting with the ridge forming direction can be adopted. In the above embodiment, one ridged body 12
However, a ridged body having a structure similar to that of the ridged body 12 is arranged at a rear position in the traveling direction of the ridged body 12, or a plate-shaped ridged body having a cross-section is shaped by a ridge striking mechanism. It may be arranged so that the ridge striking operation is possible, and a structure for striking the ridge using a hydraulic mechanism may be adopted as the structure of the ridge striking mechanism.

Further, in the above-mentioned embodiment, the ridge body 12 and the earth cutting rotor 32 are rotated by the hydraulic motor, but they can be rotated from the main shaft 7 of the tractor 1 through a mechanical transmission mechanism. On the contrary, a structure in which the rotary rotor 5 is rotated by a hydraulic motor may be adopted.

[0025]

As described above, according to the present invention, when the tractor travels along the old ridge, the embankment mechanism raises the field mud on the ridge to the old ridge, and the cover member prevents the mud from scattering and jumps up. The mud soil is prevented from scattering outside and falls by its own weight.On the other hand, the soil piled up on the old ridge is compressed and adjusted by the ridged body rotating by the rotating mechanism, and the ridged body can be trimmed on the ridge upper surface. It consists of an upper rotary body part with an outer peripheral surface and a side rotary body portion 14 with an outer peripheral surface that is integrally formed on the machine frame side surface of this upper rotary body part and that can adjust the slope on one side of the ridge. Since it is formed in the shape of a rotating roll, the ridged body rolls on the ridge surface while rotating forcibly laterally, which allows the ridged body to smoothly advance its ridges and improve the finished state of the ridge surface. Then, the upper surface of the ridge and the slope of the ridge are struck by the ridge striking mechanism. Since tightened tapping by furrow 叩体, ridge is tightened been reliably hit, it is possible to obtain a correspondingly strong ridge.

Moreover, in this case, the upper surface of the old ridge can be ground by the earth-moving mechanism, and the embankment mechanism is used to embed on the ground surface of the old ridge. Can be increased, so that a strong ridge can be obtained.

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