JP 2000-041403 A (Prior Art 1) JP 2012-060979 A (Prior Art 2)

  The dredge forming machine is generally provided with a banking portion having a rotary tiller portion with a rotary claw provided on a rotating shaft for excavating a part and a skirt portion of the old dredge at the front portion in the traveling direction and raising the excavated soil on the old dredge side. Behind it, a conical molding disk that molds the side of the saddle and a cylindrical molding roller that molds the top of the saddle rotate together, compressing the embankment raised by the embankment to the former scissors A scissor forming part is provided to form a scissor forming work part, and the scissor forming work part is offset to the side of the tractor and the scissor forming work is performed while running parallel to the old scissors. At this time, the conical disk and the cylindrical roller of the ridge forming portion compress the soil and rotate at a speed higher than the traveling speed to apply the soil to form the ridge. However, if this is repeated year by year, a part of the ridge is excavated by the embankment part at the time of forming the ridge, but the excavated soil is returned as it is and repainted, and has functions such as discharging the soil. However, there is a problem that the width of the ridge is expanded by the soil scraped by the embankment part and the field area is reduced. For this reason, there has been a need to perform an appropriate mold forming operation after setting the desired width of the mold before the mold forming operation.

  Prior art 1 is a conventional straw molding machine, and the soil scraped up by the embankment is solidified as it is and does not correspond to preventing the width of the straw from expanding. In the case of the prior art 2, the grinder is a dedicated machine for scraping off the upper surface and slope of the reed. For this reason, the user needs a dedicated machine for shaving in addition to the saddle forming machine, which imposes a burden on the purchase cost and also requires troublesome work such as replacement during work.

  Therefore, an object of the present invention is to provide a scissor forming machine that can easily perform scissor forming work and scissor work for adjusting the width of the scissors in a scissor forming machine without using a dedicated machine or the like. It is in.

In order to solve the above-mentioned problem, the embankment was moved along the dredging formation site, and the embankment portion for supplying soil to the dredging formation location in a raised state, and located in the rear of the embankment moving direction, was embanked in the embankment portion A growth part that presses the soil to form a ridge, and the growth part is an upper surface roller that passes while rotating on the ridge formation portion where the soil is raised in the embankment part, and a rotation center of the upper surface roller. In the dredge forming machine, which is a conical disk with an inclined surface facing the head, the embankment part rotates a rotor shaft with a number of digging claws radially provided on the rotating shaft, and a part of the old paddle and a part of the field scene are A state in which the excavated soil is raised to the heel side, the soil is piled up at the heel formation site and pressed by the growing portion disk located at the rear, and the ridge is formed, and the growing portion disk located at the rear Raise it without using it, part of the old fence and part of the farm scene Ridge molding machine excavated soil characterized in that it is switched by switching a cover which forms part of the rotor shaft cover which covers the rotor shaft outer circumference and state by releasing the direction working cutting ridge away from rib Propose.

  According to the present invention, the embankment portion can be switched between a state in which the excavated soil jumps up to the dredge side and the soil is piled up at the dredging site, and a state in which the excavated soil is released in a direction away from the dredge. When scraping the widened ridge, it is possible to easily scrape the ridge by releasing the excavated soil away from the ridge, and when forming the ridge, the excavated soil jumps up to the heel side to form the ridge By making the soil piled up at the location, normal dredging can be performed. In this way, since one machine can be used for both the wrinkle forming work and the shaving work, a plurality of machines are not required, and the purchase cost can be reduced. Also, work such as changing to a tractor during work is unnecessary, and work efficiency is good. In addition, the excavation depth of the rotor part of the embankment part and the relative height of the conical disk rotation center of the growth part can be changed, so that the conical disk side can be raised to the position of the conical disk during the shaving operation. The work efficiency is good because the shaving width can be arbitrarily selected without being affected.
