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

[0002]

2. Description of the Related Art Conventionally, as a furrow coater equipped with a rotary having a tillage claw, it is connected to a traveling machine body such as a tractor and travels along an old ridge while being mounted parallel to the longitudinal direction of the traveling machine body. The side of the old ridge and the paddy field adjacent to it are excavated by the tilling claw attached to the rotary shaft, and the excavated soil is scraped in the direction of the old ridge, and the soil is tamped with a vibrator to form a new ridge. doing.

[0003]

However, the conventional ridge coater described above still has the following problems.

That is, since the above rotary shaft is parallel to the front-back direction of the traveling machine body, that is, it is mounted in the traveling direction of the ridge coating machine, the rotating surface of the tilling pawl is orthogonal to the traveling direction of the ridge coating machine. Then, the force in the thrust direction acts on the tilling pawl, power consumption increases, and there is a problem that abnormal wear of the tilling pawl occurs.

Further, the tilling claw is required to have a function of cultivating the side surface of the old ridge and the rice field adjacent to it, and scraping the cultivated soil in the ridge direction. As it progresses, the rotation path of the tilling claw always passes through the uncultivated old ridge and the paddy field close to it, so that the soil scraping effect is reduced and the soil enough to form new ridges can be scraped. There was also a problem that I could not do it.

It is an object of the present invention to provide a rotary structure of a ridge coater which can solve the above problems.
