Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge side excavating device for a soil uplifting work machine capable of excavating sloped side surfaces of a green onion ridge on both sides to raise soil above the ridge.

[0002]

2. Description of the Related Art Conventionally, a rotary working machine capable of bouncing up mud above both onion ridges on both sides is mounted on a management machine, and the slopes of the onion ridges on both sides are inclined forward of the rotary work machine. As shown in FIG. 10, in a green onion earthing implement constructed by equipping both taper knives capable of excavating side surfaces, as shown in FIG. At the same time, they are inclined inwardly by an angle α with respect to the traveling direction indicated by arrow a.

[0003]

However, since both taper knives C1 and C1 are inclined in a figure eight shape in a plan view as described above, the controllability of the management machine and Depending on the running resistance to the control machine and the rotary working machine, one of the taper knives pierces the sloped side surface of the green onion ridge D as shown by the arrow B or C, and the aircraft is obstructed in its straightness. There was a problem that the sloped side of the ridges D and D could not be excavated evenly, and the soil was biased, which made the control machine difficult to operate and poor in workability.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made to solve such a problem and provides it so that it can be suitably implemented. Therefore, a rotary that can raise mud above the green onion ridges on both sides. In addition to mounting the working machine to the management machine, in the forward direction of the rotary working machine, in the earthwork working machine for green onion, which is equipped with both taper knives capable of excavating the inclined side surfaces of the green onion ridges on both sides,
In the front part of the both taper knives inclined in the shape of an inverted figure when viewed from the front, excavation surfaces are formed so that the front end edges are blade edges and are parallel to the traveling direction of the machine body. In the same manner as the above, the guide surfaces that are inclined and have an eight-character shape in plan view are formed by bending.

[0005]

Therefore, since the excavation surfaces of both taper knives are parallel to the traveling direction, both excavation surfaces are pressed against the side surface of the ridge after excavation, but stable to the left and right sides. It is possible to effectively move the aircraft straight ahead, and while the excavation surfaces evenly excavate the sides of both ridges, the guide surface guides the excavated mud well to raise the soil evenly to both ridges. Can be done.

A knife support cylinder 28 slidably fitted on the front wheel stay 26 is fixedly attached by a set bolt 29, and both taper knives C, C are arranged on the left and right sides of the knife support cylinder 28. However, in front of both taper knives C and C that are inclined in a figure eight-fold shape when viewed from the front, the excavation surfaces 2 and 2 are formed in front of the blade edge 1 and parallel to the traveling direction of the aircraft (indicated by arrow a). Behind both excavation surfaces 2 and 2, guide surfaces 3 and 3 that are inclined in the up-down direction and have an 8-shape in plan view are respectively bent to form a blade edge 1 and excavation surface 2.
Also, the guide surfaces 3 are formed so that their vertical heights are the same.

As shown in FIG. 9, it is possible to make the angle θ2, which makes it possible to adapt to the inclination of the side surface of the ridge D. Further, by shortening the connecting length of each support plate 3, both taper knives can be formed. Since the distance between C and C can be reduced, it is possible to adapt between the ridges D and D where the groove width becomes narrow.

Further, as shown in FIGS. 7 to 9, the extension covers 20 and 20 are expanded and contracted and the guide folders 22 and 2 are extended.
When the inclination angle β of 2 is adjusted, the direction of the mud splashed up by the rotary 13 can be effectively adjusted.
