Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge coater.

[0002]

2. Description of the Related Art Conventionally, a rotary portion for excavating a slope of an old ridge and a rice field at the side of an old ridge to scrape soil toward a ridge side is formed behind a traveling machine. There is a ridge coating machine in which a ridge forming part for squeezing soil gathered by vibration of a ridge formed body is formed.

[0003]

However, in the conventional ridge coater, the soil excavated in the rotary portion and raked toward the ridge side is crushed by vibrating the ridge shaped body in the ridge shaping portion. Since the new ridge was formed, the vibration of the ridge molded body was propagated to the ridge immediately after the ridge molded body, and the ridge was sometimes collapsed.

[0004] In particular, in soft land and black and white land, the vibration of the ridge forming portion alone causes poor tightening of the ridge, making it difficult to improve the finish of the ridge surface.

[0005]

In order to solve the above-mentioned problems, the present invention excavates a slope of an old ridge and a rice field at an old ridge behind a traveling machine to scrape soil toward the ridge. Along with forming the rotary part, a ridge forming part is formed behind the rotary part, which tamps the soil swept by the vibration of the ridge forming body,
In addition, an auxiliary pressure reducing section is formed behind the ridge forming section, and the auxiliary pressure reducing section is configured to rotationally drive the pressure reduction roller to compress the ridge.

[0006] The auxiliary pressure-reducing portion is composed of a pressure-reducing roller for relieving at least one of the slope of the ridge and the upper surface of the ridge.
