DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge coating apparatus for continuously forming ridges in, for example, a field.

[0002]

Conventionally, Japanese Utility Model Laid-Open No. 3-12
No. 2603, or Japanese Patent Application Laid-Open No. Hei 8-149902, as shown in the rear, a ridge coater main body case is mounted on the rear side of the tractor, and the direction is changed by horizontally rotating the ridge coater main case on either the left or right side of the tractor, There is a technique which can omit the hand-painting work by painting the ridge end left unpainted by the forward work of the tractor by the backward work. However, in the above-mentioned prior art, since the upper and lower fulcrum shafts are provided on the base frame mounted on the tractor and the ridge coater main body case is provided between the upper and lower fulcrum shafts, the strength of the upper surface side of the ridge coater main body case is reduced. It is necessary to increase the size, and there is a problem that it is not easy to simplify the structure of the ridge coating machine main body case and to improve the assembling / disassembling workability. In addition, since the ridge coating machine main body case is fixed by providing a hook or a pin on the base frame, it is necessary to perform vibration isolation of the ridge coating machine main body case in which large vibration is easily generated by the ridge coating work by the hook or the pin, There is a problem that the hook structure cannot be easily simplified, and the fulcrum shaft portion and the like are easily damaged only by the connection of the hook or the pin that causes backlash. In addition, a shaft for transmitting the PTO driving force of the tractor is provided on the base frame, and the shaft is removably connected to the PTO input shaft of the ridge coating machine main body. There is a problem that the direction changing operation of the case cannot be easily performed.

[0003]

SUMMARY OF THE INVENTION The present invention, however, comprises a soil treatment section for breaking up and closing a ridge, and a shaping section for compacting the soil to form a new ridge. In a ridge coating device for continuously forming ridges, left and right soil treatment units are attached to the rear left and right sides of a tractor, and a shaping unit is attached to a rear side of each of the left and right soil treatment units so that the position can be freely changed. It is configured to be able to perform both left painting work and right painting work by forward running of the tractor.The ridge coat body case is connected to the link mechanism of the tractor, and the left and right soil treatment parts can be attached to the ridge paint body case, and shaped. By mounting only the part so that the position can be changed freely, the direction changing structure and transmission structure of the shaping part can be simplified and the direction changing operability can be easily improved, and either the left painting work or the right painting work of the tractor can be performed. By reverse Operator is to obtain aim to obtain without a problem to be a rearward position, the improvement of left painted and right coating workability can both work by forward travel of easy tractor operated easily by performing.
