JP 2014-90685 A

  The dredge forming machine is generally provided with a banking portion having a tilling rotor portion with a claw claw provided on a rotating shaft for excavating a part and a hem portion of the old rod at the front part in the traveling direction and raising the excavated soil on the old rod side. Behind it, a conical forming disk for forming the side of the ridge and a cylindrical upper roller for forming the upper surface of the ridge rotate together, compressing the embankment raised by the embankment into the old culvert, A forming part to be formed is provided, and the hook forming work part is offset to the side of the tractor, and the paddle forming work is performed while running parallel to the old paddle. At this time, the conical disk and the cylindrical upper surface roller of the forming portion compress the soil and rotate at a speed faster than the traveling speed to apply the soil to form the ridge. The tilling rotor portion provided with the conventional excavation pawl is in a cantilever state in which only one base side is held in contact with the old rod and is held only on the base side to which the driving force is input. For this reason, when trying to increase the working speed, the load concentrates on the base side of the rotary shaft of the tilling rotor portion, and in the worst case, the working speed is broken. For this reason, there is a problem that work efficiency is poor because work speed is restricted.

  The glazing machine of the prior art 1 is intended to improve the working efficiency by reducing the amount of cutting of the main body of the embankment body and reducing the load on the embankment body. For this reason, there is a possibility that the embankment may not be evenly embanked on the upper surface or side surface of the fence due to insufficient soil volume.
