[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ridge coating device for continuously forming ridges in a field or the like by supporting a ridge coating machine in an elevating and lowering manner via a three-point link mechanism behind a traveling vehicle such as a tractor.

[0002]

[Prior art]

 When a ridge coater sinks against the surface of a ridge during conventional ridge formation work, the height of the ridge is adjusted by manually operating the work implement lift lever on the machine side each time.

[0003]

[Problems to be solved by the device]

 However, in the case of such wetland work, there is a problem that the up and down movement of the ridge coater with respect to the surface of the paddy field is drastic and it takes a lot of time and effort to adjust its height, resulting in extremely poor operability. It was

[0004]

[Means for Solving the Problems]

 Therefore, the present invention has a structure in which the ridge coater is supported to be movable up and down via a link mechanism on the traveling machine body, and is provided with a paddy sensor for detecting the vertical position of the ridge coater on the paddy field. By controlling the ridge coater up and down based on this, good ridge formation is performed by automatically maintaining the height of the ridge surface at a constant level with respect to the paddy field, and it can also be hand-operated and is easy to operate. In addition, the slip on the traveling machine side that occurs when the ridge coater sinks on the rice field can be reduced, and traveling performance and stable maintenance of the tiller can be achieved.
