DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pretreatment body side plate structure of a ridge coating machine which works by attaching a ridge and a pretreatment body to a rear part of a traveling machine body in a left-right offset state.

[0002]

2. Description of the Related Art Conventionally, a ridge coating machine in which a main body frame is mounted on a rear portion of a traveling machine body and a ridge body and a pretreatment body are provided on the main body frame so as to be offset to one of right and left is disclosed in, for example, JP-A-Hei. No. 8-9706.

[0003] The above-mentioned ridge coating machine of the prior art is rotatably driven by receiving power from a traveling body moving forward, and moves the pre-treatment body to the original ridge on which the pre-treatment body and the pre-treatment body are offset. The excavated soil is applied to the slope and upper surface of the original ridge by the ridge to make the ridge.

[0004]

As described above, in the conventional levee coating machine, the ridge and the pre-treatment body are offset to the left and right sides of the rear part of the traveling body, and the levee is advanced while the body is advanced. The soil excavated by the pretreatment body is reclaimed to the original ridge side, but the side plate provided on the ridge side is fixed, so that when the ridge coating machine moves up and down, There was a case where the side plate did not move up and down with respect to the unevenness of the surface, and the soil came off from the side plate to the outside.

A side plate of a well-known rotary tilling apparatus has a side plate movable up and down and forward and backward by a pair of left and right link bodies with respect to the apparatus main body. In the former case, a gap is formed between the main unit and the main unit when the side plate follows the vertical movement of the main unit and the unevenness of the field scene. The soil may leak out from the side plate to the outside, and it is difficult to form a gap with the latter,
There has been a problem that the apparatus has poor followability with respect to vertical movement of the apparatus body and irregularities in the field scene. The present invention has been made to solve the above problems.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a main body frame mounted on a rear portion of a traveling body, and a ridge and a pretreatment body are provided on the main body frame in a left-right offset state. In the ridge coating machine, the side plate provided on the side of the pretreatment body is supported by a fulcrum that is slidable in the vertical direction and rotatable in the front-rear direction and a link body that rotates in the front-rear direction. Features.

[0007]

According to the construction described above, the ridge coating machine of the present invention rotates the side plate provided on the side of the pretreatment body vertically and slidably in the front-back direction, and pivots in the front-back direction. By supporting with the link body, the up and down adjustment of the side plate can be easily performed, the up and down movement of the pretreatment body during work, and freely follow the unevenness of the field scene, excavated by the pretreatment body and the original ridge side Do not allow the soil to be removed to the outside of the side plate.
