DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge forming machine which is attached to a traveling vehicle and sequentially forms ridges in the traveling direction.

[0002]

2. Description of the Related Art In a conventional ridge forming machine, a mechanism for hitting a ridge upper surface and a side surface has become popular, and in recent years, as proposed in Japanese Patent Application Laid-Open No. Hei. Having a ridge forming device consisting of a conical rotating body that forms the ridge side surface, setting the peripheral speed of the rotator of the ridge forming device faster than the traveling speed of the towing vehicle, and kneading the ridge outer surface by the slip action Some try to compact tightly.

[0003]

However, when using such a conventional ridge forming machine, there is a problem that the old ridge shape of the field and the weathering state greatly restrict it. That is, while the formation of a simple middle ridge has few restrictions, the upper surface and the side surface of the old ridge have much side surface collapse and the upper surface is relatively hard and less weathered. Therefore, when a conventional inner conical rotator is introduced into such an old ridge, the peripheral speed of the small-diameter cylindrical rotator on the upper surface of the ridge is restricted by an appropriate peripheral speed setting on the inner conical rotator side. In addition, the kneading and tightening action on the upper surface of the ridge was limited, and there was a problem that the finishing was unstable. In particular, there is a problem that the corners and the shoulders which join the upper surface and the inner slope of the formed ridge are gently formed and easily collapse by contact or impact.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a ridge forming machine attached to a traveling vehicle and sequentially forming ridges in the traveling direction thereof. Equipped with an embankment device that supplies a raised state, and a ridge forming device that forms a ridge by compacting the soil piled in the ridge forming portion,
The ridge forming apparatus includes a cylindrical rotary member having a circumferential surface forming the upper surface of the ridge, and an inner conical rotary member having a divergent conical surface forming the inner surface side of the ridge. The cylindrical rotator and the inner conical rotator are forcibly driven by the rotation shaft, and the cylindrical rotator has a divergent conical flank having an arc-shaped cross section that smoothly connects to the inner conical rotator, and is larger than the inner conical rotator. In the ridge forming machine that rotates at a high speed, the pipe shaft of the inner conical rotator that is forcibly driven is fixed to the eccentric mounting hole provided in the flange portion of the first hub, so that the inner conical rotator rotates with respect to the axis of the cylindrical rotator. We propose a ridge forming machine characterized by a series of eccentric bodies.

[0005]

When the towing device and the ridge forming device are operated with the progress of the towing vehicle, however, the soil is continuously supplied to the collapsed upper and side surfaces of the old ridge by the burying device. The cylindrical rotator that is forcibly driven and accelerated by the rotation of the inner conical rotator compacts the upper surface of the old ridge in a clean plane while kneading the supplied embankment soil, and simultaneously rotates coaxially. Because the embankment is kneaded into the foot of the ridge while embedding the embankment, tight gaps such as mouse holes are tightened to form a firm ridge. In particular, the shoulder of the ridge, which is formed by the forced rotation of the cylindrical rotating part having an arc-shaped flared arc-shaped flange compared to the conical rotating body, is further kneaded and tightened, so that it becomes strong. Withstands shock. Also, since the inner conical rotating body is eccentric with respect to the cylindrical rotating body or inclined toward the traveling direction,
The embankment embraced at the foot of the ridge is kneaded by applying intermittent pressure, so that a stronger ridge is created. In addition, since the attachment means of the extension member is provided on the outer peripheral edge of the inner rotating body, in the case of a ridge higher than the setting, an extension plate of a cone may be attached as an auxiliary. Alternatively, if auxiliary fins are attached to the lower end of the ridge inner rotating body, the inner corners of the ridge are compressed and compacted.
