Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ridge coating device for mechanically forming ridges in a paddy field by a ridge shaping plate.

[0002]

[Prior Art]

 In this kind of ridge shaping work, when trying to embed scattered mud on a shaving trace removed by pretreatment with a rotary tool, etc., the way the mud flies differs depending on the soil quality, so the bolts must be removed within the mud cover. The opening and closing of the mud shutter has been adjusted by adjusting the mud flying conditions.

[0003]

[Problems to be solved by the device]

 However, in the case of such a conventional means, the mud cover is filled with mud, so that the work is difficult to perform and the adjustment requires time and labor.

[0004]

[Means for Solving the Problems]

 Therefore, according to the present invention, a mud shutter for guiding the scattered mud from the rotary to the ridge surface is provided inside the mud cover, and a shutter operating member for adjusting the opening / closing of the mud shutter is provided outside the mud cover. It is very easy to open and close the mud shutter.
