[0022]

As described above, according to the ridge coater of the present invention, the following effects can be obtained.

[0023] At the same time as the ridge formation with the pretreatment body and the ridge body, a grooving device that forms a groove inside the formed ridge was provided, so the ridge body rotates the soil cultivated by the pretreatment body while rotating. However, at the same time as the ridges, grooves of a predetermined shape can be formed inside the ridges by a groove cutting device.

[0024] The groove cutting device is a groove that forms a groove by pressing a tilling mark plowed by the pretreatment body by approaching the inner end of the polygonal conical drum of the levee body behind the pretreatment body and the levee body. A shaping roller is provided so that it can be adjusted up and down, so that the soil cultivated by the pre-treatment body is leveled while the ridge is rotating, and at the same time as the ridge, the cultivation marks by the pre-treatment body are adjusted up and down. Thus, a groove having a predetermined width and depth can be formed in a state in which the groove is hardly collapsed.

[0025] A groove cutter is provided behind the pretreatment body and the ridge body, facing the inner end of the polygonal conical drum of the ridge body, and a coulter for cutting a tilling mark plowed by the pretreatment body downward. And a soil discharge plate that discharges the soil between the coulter and the inner end of the polygonal conical drum of the ridge body to form a groove, so that the soil tilled by the pretreatment body is conditioned. The ridge is rotated while the ridge is rotating, and at the same time as the ridge, the cultivated mark tilled by the pretreatment body is cut downward by the coulter. The soil between them can be discharged to the outside by means of a soil discharge plate to form a clean groove in which no extra soil remains.

[0026] The grooving device includes a pressure roller that presses the base of the ridge shaped by the polygonal conical drum in close proximity to the polygonal cone drum of the rower, behind the pretreatment body and the rower, and the pressure roller. The soil cultivated by the pretreatment body inside is drained to form a groove by discharging the soil cultivated by the pretreatment body. The base of the ridge, which was shaped at the same time as the ridge, is pressed by the pressing roller, so that the base of the ridge is not easily collapsed.
The soil discharge plate allows the soil to be discharged and a clean groove without excess soil to be formed.
