Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ridge coating device for mechanically producing ridges in a paddy field.

[0002]

[Prior Art]

 Conventionally, there has been a technique in which weeds on the surface of the original ridge are removed and then mud is applied by a ridge shaping plate to form a new ridge.

[0003]

[Problems to be solved by the device]

 In the above conventional technique, the embankment was shaped by the ridge shaping plate to form the ridges, but since the ridge surface after shaping was not smoothed, many small irregularities were easily formed on the ridge surface, and the ridges were also formed. There was a problem in work such that the shape and the peeling easily occurred.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is a ridge coating device for vibrating a ridge shaping plate with a vibrator, in which an elastic auxiliary plate for ridge shaping is extended to the rear side of the ridge shaping plate and a ridge upper surface formed by the ridge shaping plate. It is characterized in that the elastic auxiliary plate is bent according to the inclination of the slope and the rear side of the elastic auxiliary plate is folded in two and attached, and the surface of the ridge formed by the ridge shaping plate is subjected to the elastic deformation. Since it is smoothed by the auxiliary plate, ridges can be finished on the mirror-like surface by eliminating small irregularities, and the elastic auxiliary plate can prevent the shape of even soft soil from deforming due to the elastic force of the elastic auxiliary plate to form ridges in an appropriate shape. Also, the shoulders on the boundary between the upper surface of the ridge and the slope can be finished in an appropriate shape by the elastic auxiliary plate, and the workability of ridge shaping can be easily improved.
