Description

[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.

[0002]

[Prior art]

 Conventionally, when continuously forming ridges with a ridge shaping plate vibrated by a vibrator, for example, the work of removing weeds and the like on the surface of the original ridge, and the work of crushing the soil and covering the surface of the original ridge with the soil tillage rotary nail are performed. It was done by rotation.

[0003]

[Problems to be solved by the device]

 In the above-mentioned prior art, since a plurality of rotary pawls are rotated in substantially the same plane in a plan view or a side view, soil easily stays between the rotary pawl and the main body case in which the rotary pawl is provided. The accumulated soil grows up to the mud cover provided on the side of the case for guiding the soil supply, and the efficiency of soil collection to the ridges decreases significantly in the short time after the start of the work, and the gap between the multiple rotary claws and the main case is reduced. If the soil is prevented from staying between them by reducing the size of the soil, the amount of soil accumulated on the joint between the main body case and the mud cover and on the mud cover will increase, and the amount of soil deposited on the upper surface of the ridge and the soil due to the rotary claw will increase. There was a problem such as a turn around.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, in a ridge coating device in which a plurality of rotary pawls are attached to a rotary pawl shaft projecting from a main body case and the rotary pawl crushes the ridge coating soil, at least one of the plurality of rotary pawls is The eccentric rotary claw is displaced outside the rotation path of the rotary claw of 1., and the eccentric rotary claw is brought close to the main body case to remove accumulated soil between the main body case and the main body case. Since the soil accumulated between the rotary claws is scraped off by the eccentric rotary claws, it is possible to save the trouble of removing the accumulated soil by stopping the ridge coating work, and the ridge coating work can be performed continuously to improve the workability easily. In addition, it is possible to easily reduce the soiling on the upper surface of the ridge and the rotation of mud by the rotary claws, and it is possible to easily improve the soiling efficiency by the rotary claws.
