Is configured. It should be noted that the base trimming rotator 31 may be forcibly rotated by obtaining a power source.

Since this embodiment has the above-mentioned structure, when the traveling machine body 1 is run along the old ridge W and the power take-off shaft 7 is rotated, the rotary rotor as the embankment body 5 turns the old field mud into the old ridge. Continuously bouncing up on the ridge and raising it, the cover member 11 prevents the mud from scattering upwards and sideways of the ridge, and the mud that has been flipped up prevents outside scattering and falls by its own weight, while on the other hand, the old ridge The ridged soil is driven by the ridge adjusting mechanism 14 and is struck by the reciprocating ridge striking action of the ridged body 12 having a shape that fits the upper surface of the ridge W and one side surface of the ridge W for rectifying work. As a result, the base W _{3, the} slope W _{2 and the} upper surface W ₁ of the ridge W can be reliably clamped, and thus a stronger ridge can be obtained, and further, the embankment mechanism 4 is provided at the front position of the machine frame 3.

It is possible to perform various adjustment work.

In this case, the base of the ridge W is the base ridge-rotating body 3
1, the base ridge-rotating body 31 is pressed and adjusted by 1 to form a conical roll shape, and has a substantially conical outer peripheral surface 3 that fits one slope of the ridge.
Since the base portion W ₃ of the ridge is pressed and adjusted by 1a, the base adjustment rotator 31 can be easily adjusted up and down along the ridge slope according to the shape of the ridge. Since the rotating body 31 is formed with the penetration convex portion 31c that can be penetrated into the field M surface, the ridge-reaction force is favorably received.

Further, in this case, the upper surface portion of the old ridge can be ground by the earth cutting mechanism 23, and the embankment mechanism 4 can be placed on the ground ridge surface.
As a result, the embankment will be filled, so that the binding property between the old ridge and the embankment can be enhanced, and thus a stronger ridge can be obtained.

The present invention is not limited to the above-described embodiment. For example, as the embankment mechanism 4, a rotary rotor having a rotation axis line in a direction intersecting with the ridge forming direction may be adopted. Although one ridge is provided in the above-described embodiment, it can be applied to a structure in which two or more ridges are sequentially arranged, and as a structure of the arranging mechanism, a hydraulic mechanism is used to strike the ridge. It can also be applied to structures, vibrator structures, unbalanced rotation structures using eccentric weights, and other types of vibration mechanisms that tighten ridges.

[0023]

As described above, according to the present invention, when the traveling vehicle is driven along the old ridge, the embankment mechanism continuously lifts up the field mud on the ridge to the old ridge and raises it on the other hand. The heaped ridge is tightened by the arranging operation of the arranging body driven by the arranging mechanism to perform the arranging work, and the embankment mechanism is arranged at the front position of the machine frame. Since the above-mentioned ridge body is arranged at the rear position of the machine frame, the projecting length from the rear part of the traveling machine body to these constituent members can be reduced, and the stability of the connection by the connection mechanism can be improved accordingly. It is possible to suppress the generation of vibrations and avoid damage to the connection part due to vibrations, and to simplify the structure of the connection mechanism by that amount. Visually Will be easy, it is possible to be carried out that much good Seiaze work.

At this time, the base portion can be firmly adjusted by clamping and adjusting the base portion of the ridge by the base adjustment rotator, and the ridge shape can be obtained by forming the base adjustment rotator into a conical roll shape. Depending on the position, the base ridge slewing body can be easily adjusted up and down along the ridge slope, and the base ridge slewing body can be adjusted by forming a piercing protrusion that can be pierced in the field scene. You can receive the ridge reaction favorably, and you can get a strong ridge accordingly.

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