In the “ridge forming machine”, the ridge forming device includes a cylindrical rotating tool that rotates around a shaft edge orthogonal to the ridge. The rotator is provided at the inner and outer ends of the rotator with an inner rotary plate having a conical surface having an inclined surface facing the center of the cylindrical body. Alternatively, together with the inner rotating plate, an outer rotating plate having an inclined surface facing the center of the cylindrical body is also provided so as to face the inner rotating body. The traveling length of the towing vehicle is smaller than the product of the circumference of the rotating body and the number of rotations of the rotating body per unit time. The running speed of the rotating body of the ridge forming device, which is composed of a cylindrical rotating tool passing through the upper surface of the ridge and an inner rotating plate and / or an outer rotating plate having a conical surface passing through the ridge side surface and forming the ridge side surface, is traveled. The speed is set faster than the traveling speed of the car, and the side of the ridge is squeezed firmly by the slip action.

[0003]

However, in the conventional ridge forming machine, both the inner rotating body and the outer rotating body have smooth surfaces, so that the soil of the field is dry depending on the type of soil in the field or the field. Sometimes, there was a problem that the tightening force on the side of the ridge was weak.

The cylindrical rotating body 42 is formed in a cylindrical shape, and is attached to the tip of the first driven rotating shaft 34. The rotation of the first driven rotating shaft 34 forcibly moves in the moving direction on the ridge forming portion H in which the soil is raised. Is rotated forward. The peripheral speed of the cylindrical rotating body 42 is set to be higher than the working speed of the traveling vehicle, and the cross section is tightened in a slip state.

Is rotated forward. Since the diameter of the first driven pulley 36 is smaller than that of the second driven pulley 37, the speed of the first driven rotation shaft 34 is set to be higher than that of the second driven rotation shaft 35, and the first driven pulley 36 and the cylindrical rotary body 42 attached to each driven rotation shaft are conical.

Therefore, the embankment device 21 and the ridge forming device 41 are moved as the tractor, which is a traveling vehicle, advances. Then, the soil is supplied to the ridge formation location H in a raised state by the embankment device 21. That is, the soil is continuously supplied to the collapsed upper surface portion and side surface portion of the old ridge at the ridge formation portion H in a raised state. The diameter of the conical rotating body 43 increases as it goes toward the rotational driving force supply side, that is, toward the traveling vehicle, and its surface is divided into radial divided pieces 44. The divided pieces 44 are provided with an advance angle A with respect to the traveling direction. Since the adjacent divided pieces 44 are connected to each other with a clearance angle B, the abutment surface a first comes into contact with the embankment, and is kneaded by applying intermittent pressure while holding the embankment against the skirt of the ridge. Therefore, a strong ridge is formed.
Further, since the divided pieces have a clearance angle B in the traveling direction and repeat the intermittent pressure, even if the viscous soil tries to adhere, the viscous soil is immediately separated, so that the adhesion of the soil does not grow.

In another embodiment shown in FIGS. 5 and 6, each of the divided pieces 44 of the conical rotator 43 is a substantially fan-shaped independent piece. Reference numeral 45 denotes a split piece mounting board made of metal such as stainless steel. The split piece mounting board 45 is formed in a frustoconical shape with a smooth surface.

In this embodiment, the conical rotator 43 is provided only on the machine frame 11 side of the cylindrical rotator 42, but the conical rotator 43 is also provided on the tip side of the cylindrical rotator 43 to form the outer cylindrical rotator 43. And the second driven rotation shaft 35 may be used. In that case, not only the inner slope but also the outer slope is formed at the same time.
