Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge coater, and mainly relates to a ridge coater for repairing old ridges that partition a paddy field to prevent water leakage.

[0002]

2. Description of the Related Art Conventionally, as this type of ridge coating machine, as described in, for example, Japanese Patent Laid-Open No. 6-22604, a plowing claw for embedding a ridge forming portion (old ridge) in a machine frame. A rotator having a rotator is rotatably provided, and a rotary tool that is located at a rear portion of the rotary and that forms a ridge by compacting the embankment of the ridge forming portion is rotatably provided on the machine frame. The inner and outer rotating plates of the conical shape, which form the inner and outer surfaces of the ridges and have a large diameter toward the outside, are fixed to both ends of the cylindrical rotating body that forms the cylindrical rotating body. A configuration is known in which a conical rotary plate having a large diameter outwardly is fixed to one end of a body, and each of the rotating tools is rotationally driven in a downcut direction.

[0003]

In the configuration described in the above publication, the conical inner rotary plate and the outer rotary plate of the rotating tool are driven to rotate in the downcut direction, and the conical inner rotary plate and the outer rotary plate are also driven. The rotating plate has a large peripheral speed difference between the large diameter part and the small diameter part, that is, the peripheral speed of the large diameter part located on the hem side of the ridge is faster than the peripheral speed of the small diameter part located above the ridge hem. Therefore, when repairing the inner and outer surface of the old ridge with the conical inner and outer rotating plates, the mud is applied while falling down from the upper part of the side of the old ridge toward the lower hem. It has a strong tendency to be attached.

Therefore, the mud is compacted in the large diameter portion of the inner rotary plate and the outer rotary plate where the peripheral speed is high, while the hem of the old ridge has a relatively large amount of soil, but the upper part of the old ridge is soil. The mud will be compacted when the amount is insufficient or too small.
Therefore, the hem of the old ridge is repaired in a tightly compacted state, but the upper part of the old ridge cannot be sufficiently tightly compacted and is repaired in a relatively soft and compacted state. There is a problem that the ridges tend to collapse from the upper part, and the ridges as a whole may not be firmly restored.

The present invention has been made in view of the above point, and the hem portion of the old ridge, which tends to be in a state where the amount of soil is relatively large due to collapse of mud, is a conical side portion of the side coating body. The peripheral speed of the coated surface is small and the clay is applied and compacted in a small diameter area, and the upper part of the side of the old ridge where the amount of soil tends to be small is the conical side coated surface of the side coated body. It can be compacted while applying mud on the large diameter part where the peripheral speed is fast.Therefore, the hem part of the side part of the old ridge and the upper part of the side part of the old ridge can be restored in a sufficiently tightly compacted state. It is an object of the present invention to provide a ridge coater which is hard to collapse and can be firmly restored as a whole, and which has a good finished state and improved durability.

As for the extension coated body 98 having the extension side coated surface 99, a plurality of types having different heights of the extension side coated surface 99 are prepared. Since other configurations are the same as those in the above-described respective embodiments, the reference numerals of the above-mentioned respective embodiments are entered and the description thereof will be omitted.

Then, the screw holes of the mounting plate 63 of the side coating body 58
63a is screwed with the screw 101 of the extension coating body 98 selected according to the height of the side portion of the old ridge B, and the circular bottom plate 100 is joined to the mounting plate 63. Extension coating on the lower end
98 is attached and the side coated surface 6 of the side coated body 58 is
6 and 94, the extended side coating surface 99 of the extended coating body 98 is continuously provided,
In addition, the side coating surfaces 66, 94 and the extended side coating surface 99 constitute a series of conical coating surfaces having a downwardly reduced diameter.

Then, the side portion of the old ridge B is directed downward at a predetermined height with a series of conical coating surfaces consisting of the side coating surfaces 66, 94 and the extended side coating surface 99. It is possible to restore to the tapered side surface portion C that has been expanded.

[0071]

According to the invention of claim 1, the ridge coating body has a cylindrical upper coating body for repairing an upper portion of the old ridge and a side coating body for repairing a side portion of the old ridge. However, the side coated body,
It is fixed to a vertical rotation shaft that is driven to rotate by the output from the drive means, and the outer peripheral portion of the former ridge is contracted downward to restore the side portion of the old ridge to a tapered side surface portion that is expanded downward. Since it has a conical side coated surface with a diameter, the hem of the old ridge, where mud is likely to collapse and produce a relatively large amount of soil, is the circumference of the conical side coated surface of the side coated body. Slow speed While compacting while applying mud in a small diameter part, the amount of soil tends to be small The upper part of the side of the old ridge has a high peripheral speed of the conical side coating surface of the side coating body It can be compacted while applying mud on the large diameter part, therefore, the hem part of the side part of the old ridge and the upper part of the side part of the old ridge can be compacted and restored sufficiently. The ridges are hard to collapse and can be firmly restored as a whole, and the finished state is It is possible to improve the durability good.

According to the second aspect of the present invention, the side coated body of the ridge coating body has a vertical rotating shaft which is rotationally driven by the output from the driving means and has a predetermined inclination with respect to the axis of the rotating shaft. Since it is fixed by tilting at an angle, it is eccentrically rotated about the rotation axis and the mud is strongly pressed against the conical slanted side coating surface of the side coated body while being firmly pressed and compacted. be able to.

In the ridge coating machine according to the third aspect, the side coating body of the ridge coating body has a side coating surface that is formed in a polygonal shape and has a reduced diameter on the outer periphery thereof. Therefore, the mud is pressed against each corner of the side-applied surface while being strongly pressed and can be sufficiently compacted.

In the ridge coating machine according to the fourth aspect, the side coated body of the ridge coated body has a cone-shaped extension side whose lower end is reduced in diameter continuously from the side coated surface. Since the extension coated body having the partially coated surface is detachably provided, it is possible to easily obtain the side coated surface corresponding to the height for repairing the side portion of the old ridge with this extended coated body. The side part of the old ridge can be restored to the side part of the taper-shaped predetermined height which is expanded downward with this side part coated surface.

In the ridge coating machine according to the fifth aspect, the upper coated body of the ridge coating body is a rotation shaft in the left-right direction which is rotationally driven by the output from the driving means, and has a predetermined axis with respect to the axis of the rotation shaft. Since the slant is fixed at an inclination angle, the mud is strongly pressed against the slanted outer peripheral portion of the upper coating body that is eccentrically rotated about the rotation axis, and can be sufficiently compacted.
