The rotor shaft 22 having the excavating claws 20 is rotated by the power from the tractor, excavates part of the paddy field and the former soil, jumps up to the former side, and is embanked.

  As shown in FIG. 3, the ridge forming portion 3 located behind the embankment portion 2 includes a cylindrical rotating body 30 that forms the ridge upper surface and a conical rotating body 31 that forms the ridge side surface, and is perpendicular to the traveling direction. Rotating faster than the traveling speed around the rotating central shaft 315, the embankment embanked by the embankment portion 2 proceeds while being rotated and compacted. The conical rotator 31 has a truncated cone shape that gradually increases in diameter toward the surface, and a horizontal cylindrical cylindrical rotator 30 projects outwardly and is fixed to the top of the conical rotator 31. ing. The ridge forming unit 3 is driven together with the rotor shaft 22 of the embankment unit 2 by the power of the tractor input through the input shaft 12.

  The conical rotator 31 is composed of a plurality of radially divided pieces 310 whose surfaces are centered on the rotation center axis 315. Each of the divided pieces 310 has an outer peripheral surface whose distance from the rotation center axis 315 is the rotation direction. It is formed so as to increase in an arc shape from the front toward the rear in the rotation direction, and the rear end portion 311 in the rotation direction is a linear shape bent inwardly from the rotation outermost peripheral diameter 313 in each cross-sectional portion of the arc-shaped outer peripheral surface. It has an inclined surface 312 and is bent at an angle (α) within 45 degrees with respect to the tangent line 314 of the rotation diameter.

A conical rotator 31 is configured. At the time of forming the ridge, the reaction force due to the pressing most acts on the rear end 311 in the rotation direction of the divided piece 310 that becomes the rotation outermost peripheral diameter 313 part. Therefore, by providing an overlapping portion of the divided pieces 310 adjacent to each other in this part. It is possible to provide a conical rotating body 31 with improved strength and durability.

  Referring to FIG. 5, the state in which the conical rotator 31 of the present invention applies soil to the ridge surface will be explained. The conical rotator 31 travels in the X direction by traveling of the attached tractor and is faster than the traveling speed. Rotate in the direction and apply the soil. The conical rotator 31 is composed of a plurality of divided pieces 310, and FIG. 5A shows a state in which the rear end portion 311 in the rotational direction of the divided piece 310 is slightly closer to the heel side, and the rotation center axis. 315 has a shape in which the front side in the rotational direction of the split piece 310 is lower and the rear side is higher in an arc shape, so that the front soil is dragged to the heel side by rotational resistance, and the front soil is sequentially pressed by the traveling of the tractor. The

  FIG. 5B shows a state in which the conical rotator 31 further rotates, and the rear end 311 in the rotation direction that becomes the rotation outermost peripheral diameter 313 of the divided piece 310 is closest to the heel side, and is most toward the forming ridge. This is a state in which the pressing force increases. At this time, the front soil is efficiently embraced and gradually pressed by the surface of the divided piece 310 whose front side in the rotation direction is low and whose rear side is high in an arc shape.

  (C) of FIG. 5 is a state immediately after rotating further and passing through the state where the rear end portion 311 in the rotation direction of the split piece 310 is closest to the heel side. At this time, the inclined surface 312 that is linearly bent inward from the rear end portion 311 in the rotation direction of the divided pieces 310 is in a state substantially parallel to the traveling direction, and the rotation direction that is a stepped portion of the connecting portion between the divided pieces 310. The scratching phenomenon that has conventionally occurred at the rear end portion 311 does not occur, and the soil does not get caught in the stepped portion. Therefore, when pressing away from the soil, the soil that has entered the stepped portion is pushed backward and rises in a streak shape. The phenomenon that the surface of the mold is not smooth does not occur. The bend angle of the inclined surface 312 may be bent linearly so as to be an angle (α) within a 45 degree angle with respect to the tangent line 314 of the rotation diameter.

  FIG. 6 shows an example of a state in which the conventional conical rotating body 31x is soiled on the ridge surface, which is shown in the same state as the states (A), (B), and (C) of FIG. Yes. In FIGS. 6B and 6C, the rear end 311x in the rotation direction of the divided piece 310x is a rotation apex, and an abrupt step is formed from the apex, so that the apex is from the molding saddle surface. When leaving, the rib surface formed by the corner of the stepped portion 316 is easily scratched. Moreover, when pressing and leaving | separating, the soil which entered the level | step-difference part 316 is pushed back, it rises in a streak shape, and the phenomenon which the shaping | molding wrinkle surface does not become smooth tends to generate | occur | produce.

  FIG. 7 is a cross-sectional view showing another embodiment of the connecting portion between the divided pieces 310a of the conical rotating body 31a. The adjacent divided pieces 310a are connected in a state where the inner side surface of the inclined surface 312a on the rear end side in the rotation direction of one divided piece 310a and the outer side surface on the front end side in the rotation direction of the other divided piece 310a overlap with each other. The front end side in the rotation direction is further extended to provide an overlapping portion 317 with the arcuate rear side inner surface of the split piece 310a. Accordingly, the strength of the stepped portion 316 can be improved, and the overlapping portion 317 can be further used by the overlapping portion 317 even after the rear end side of the adjacent divided piece 310a is worn. Thus, the durable conical rotator 31a can be provided. As for the wear of the conical rotating body 31a, the outer peripheral portion having a high peripheral speed wears relatively quickly, so the overlapping portion 317 may be provided only on the outer peripheral portion.

  1 and 2 show a forward working state in which the tractor is moved forward while the working part a is offset to the right side of the tractor. The wrinkle forming machine of this example rotates the rotating frame 11 to the left, offsets the working part a to the left of the tractor, and further reverses the working part a to process the remainder of the field corner. It is also possible to enter a reverse work state in which the work is performed by reversing. The saddle forming operation is performed by offsetting the working portion a toward the tractor and running the tractor in parallel with the main rod.

  The conical rotator 31 of the heel forming portion 3 has a truncated cone shape, and a plurality of metal plates are attached to the surface of the conical rotator 31. At the time of ridge formation work, the surface of the conical rotator 31 is brought into contact with the embankment raised by the sloped embankment 2 on the side of the main fence, and the conical rotator 31 is rotated and advanced to compact the embankment. Then, an inclined surface of the Xinjiang side is formed on the side of the main shaft. The conical rotator 31 has a strength and a weight necessary for forming a side surface of the heel by being pressed against the heel.

  The cylindrical rotating body 30 has a horizontal cylindrical shape, and is attached to the tip of the truncated cone of the conical rotating body 31. The cylindrical rotating body 30 is rotated while the outer periphery is in contact with the embankment on the upper surface of the main rod during molding operation to form the upper surface of the new cage.

  The embankment part 2 is installed immediately before the ridge forming part 3 on the tractor side, that is, the front side in the traveling direction from the ridge forming part 3. The embankment portion 2 includes a rotor shaft 22 having a plurality of excavation claws 20 that are radially attached to a rotation shaft, and a cover body 21. The excavation claws 20 are provided on the rotor shaft 22 with their tips bent to the side of the sloping inclined surface. The excavation claw 20 excavates the slope of the former fence and the slope skirt of the paddy surface, and scatters the excavated soil to the side face and the upper face of the fence to form a fill.

  The cover body 21 is provided so as to cover the upper surface of the rotor shaft 22, the base side of the rotor shaft 22, and the rear surface side in the traveling direction, and prevents the soil excavated by the excavation claws 20 and guides the soil to the heel side. For this reason, the flange side of the rotor shaft 22 is open.

  The excavation blade 43 excavates the slope of the fence to be excavated and the surface of the lower part of the slope, and scatters the soil to raise the soil on the former fence. On the other hand, the conical rotator 31 of the heel forming portion 3 is rotated in contact with the entire side face inclined surface of the heel to form the side inclined surface of the heel.
