[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furrowing machine and, more particularly, to a furrowing machine for repairing an old furrow which divides a paddy field and repairing the furrow.

[0002]

2. Description of the Related Art Conventionally, as this type of ridge coater, for example, as described in Japanese Patent Application Laid-Open No. Hei 8-9706, a laterally conductive case is protruded from a machine frame connected to a tractor. In this conduction case, a rotatable excavation rotary for excavating the soil at the edge of the ridge and a guide member projecting outward from the wheel of the tractor and dropping the excavation soil from the excavation rotary onto the old ridge are fixed, respectively. In the front-rear conduction case fixed to the machine frame located behind the guide member, the embankment dropped on the old ridge is scraped into the ridge, and the ridge to be ridge-coated is rotatively mounted on the ridge. The ridge body has a cap-shaped rotator that forms a ridge slope, and a cylindrical body that protrudes in the axial direction at the center on the top side of the cap-shaped rotator. A structure in which a large number of ridge corners are formed in the outer shape of a truncated polygonal pyramid in which the corners are radially arranged. It is known.

[0003]

In the configuration described in the above-mentioned publication, the embankment of the ridge slope (side surface of the old ridge) is pressed against a large number of ridge line corners on the outer peripheral surface of the shade-shaped rotating body of the ridge. It is designed to fill the ridge slope, but at this time, it is not rare to scrape the embankment at many corners of the ridgeline, and the fill of the ridge slope cannot be fully utilized for solidifying the ridge slope.
Also, since many ridge line corners on the outer peripheral surface of the cap-shaped rotator are formed with the same radius of rotation about the rotation axis for driving and rotating this ridge, the many ridge line corners are ridges. Even if the embankment on the slope can be pressed against the ridge slope with the same pressing force and solidified, the embankment cannot be firmly pressed against the ridge slope gradually and hardened, and the ridge slope cannot be compacted sufficiently. There is a problem.

Further, in order to solidify the embankment on the ridge on the outer peripheral surface of the cylindrical body, even if the embankment on the upper surface of the ridge can be pressed against the upper surface of the ridge with the same pressing force, the solid must be gradually pressed strongly. However, there is a problem that the ridge after the ridge is easily collapsed from a corner formed at a continuous portion between the ridge slope and the upper surface of the ridge.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and makes use of the mud on the side surface of the old ridge sufficiently on the plurality of mud-coated surfaces of the side restoration body without scraping the mud. While gradually pressing firmly against the side of the ridge, the side of the old ridge can be repaired by firmly tightening the side of the old ridge to the sloping side that has expanded downward. The shoulder of the old ridge can be firmly compacted to restore it to an approximately arcuate surface, and the mud applied to the mud on the upper surface restoration body gradually presses firmly against the upper surface of the old ridge to harden it. It is an object of the present invention to provide a ridge coater that can repair the old ridge by firmly tightening the upper surface of the old ridge horizontally and as a whole the ridge is hard to collapse.
