Description

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 is generally popular, and in recent years, as proposed in Japanese Patent Laid-Open No. 6-22604, a rotary shaft for rotating a ridge upper surface is used. It has a ridge forming device composed of a conical rotating body that forms the ridge side page (2), and the peripheral speed of the rotating body of this ridge forming device is set faster than the traveling speed of the towing vehicle, and the slip action causes the outside of the ridge. There are those that try to knead the sides to make them firm and compact.

[0003]

However, when using such a conventional ridge forming machine, there is a problem that the old ridge shape of the field or the weathering state greatly restricts 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 cone-shaped rotating body is introduced into such an old ridge, the cylindrical rotating body on the upper surface of the ridge has a large restriction on its movement, while the cylindrical rotating body on the side surface of the ridge, especially at the hem, is rotated. There was a problem that the kneading and tightening actions were also restricted due to body restrictions.

[0004]

In order to solve the above-mentioned problems, a ridge forming machine according to the present invention employs the following means. That is, the ridge forming machine according to the present invention is a ridge forming machine attached to a traveling vehicle and sequentially forming ridges in the traveling direction,
An embankment device for supplying the soil to the ridge forming section in a raised state,
A ridge forming device for compacting soil filled in the ridge forming part to form a ridge, wherein the ridge forming device is provided at an inner end of a cylindrical rotating body having a circumferential surface forming an upper surface of the ridge. , An inner conical rotating body having a conical surface which forms an inner surface of the ridge and which widens toward the end, and the conical rotating body is forcibly driven by the rotating shaft and is connected to the rotation axis of the conical rotating body. It is characterized in that it does not rotate around an eccentric axis line, and that the cylindrical rotary body rotates concentrically with the conical axis line of the conical rotary body and rotates integrally with the conical rotary body. . In the ridge forming machine according to the present invention, an outer conical rotating body having a divergent conical surface forming an outer surface of the ridge is continuously provided on the outer end of the cylindrical rotating body, and the outer conical rotating page ( 3) The body and the cylindrical rotating body may be configured so as to rotate concentrically and integrally around the rotation axis. In the ridge forming machine according to the present invention, the inner conical rotating body may be configured as a deformed conical shape having a long side and a short side with respect to the rotation axis.

[0005]

However, when the earthmoving device and the ridge forming device are operated as the towing vehicle progresses, the earth is continuously supplied to the upper surface portion and the side surface portion where the old ridges are collapsed by the earthmoving device in a raised state,
It is formed as shown in FIG. The forcibly driven cylindrical rotor compacts the upper surface of the old ridge by kneading up the heaped soil that has been supplied and compacts it flatly. Since it is kneaded while applying intermittent pressure while swinging to, it tightens voids such as mouse holes to form strong ridges. When a conical rotary body with a divergent conical surface that forms the outer surface of the ridge is connected to the outer end of the cylindrical ridge of the ridge forming device, most of the old ridges are used when making new ridges. It is suitable when it is crumbled,
The ridge upper surface and the inner and outer side surfaces form a strong ridge finished as a stable surface. Further, when the inner conical rotor of the ridge forming device is formed in a deformed conical shape having a long side and a short side with respect to the axis of the cone, the conical surface is continuous from the axis in a radial direction, so that the vertical rocking action causes embankment. On the other hand, since it moves smoothly, the vibration of the entire body is also reduced.

The outer conical rotating body 20 is particularly effective when making new ridges or reforming old ridges that have almost collapsed, so it is removed and used when unnecessary.

The ridge forming apparatus 5 will be further described with reference to FIGS. A rotary shaft 11 forcibly driven is projected from the second speed change case 10, and a first hub 23 and a second hub 24 are mounted on the rotary shaft 11.

Swings up and down with respect to the hem on the inside surface of the ridge to forcibly knead and tighten the embankment for a strong finish. At this time, according to various test results, when the cylindrical rotating body 16 itself is eccentric, the surface is disturbed by the reverse vibration due to the pressure (f) of the hard layer on the upper surface of the old ridge, and at the same time the inner conical rotating body 18
