Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to 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, the back surface resistance increases, the horsepower consumption increases, and further, there is a problem that early wear and abnormal wear of the tilling pawl occur.

Further, due to the reaction force of the tilling claw, the steering wheel may be taken off by the traveling machine body, resulting in poor straightness.

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

An object of the present invention is to provide a ridge coater capable of solving the above problems.

The peel preventing groove forming claw 80 forms the peel preventing groove J on the side surface of the ridge at the time of cutting the old ridge E by the rotary 2, and the peel preventing groove J serving as the concave portion should be formed. As a result, when forming the new ridge F, the embankment is buried in the peeling prevention groove J, and the soil forming the new ridge F does not slide off the inclined surface of the ridge side face and separate. Therefore, it becomes possible to form a firm new ridge F.

As described above in the two embodiments, the ridge coater A according to the present invention has the rotary 2 rotating in the traveling direction.
Since the old ridge E and the paddy field G are dug and cut at a uniform depth, the load on the tilling claw 8 is reduced, and the power consumption of the ridge coater A can be reduced, including the traveling machine body B. The overall size can be reduced.

Further, it is possible to prevent bending, bending, premature wear, abnormal wear, etc. of the tiller 8 as much as possible.
