Claims

[Scope of claim for utility model registration] 1. A ridge shaping device installed on an earthmoving vehicle,
a support mounted on one side of the earthmoving vehicle so as to be pivotable about a vertical axis extending in the vertical direction; and a support centered about the vertical axis interposed between the earthmoving vehicle and the support. a hydraulic cylinder mechanism for turning the body; a blade for shaping an inclined surface having a cutting edge that extends upward and laterally outward at a predetermined angle, the blade being attached to the support; an upper surface shaping blade having a substantially horizontally extending cutting edge attached to the inclined surface shaping blade; an indicator for displaying the positions of the inclined surface shaping blade and the upper surface shaping blade; and controlling the operation of the fluid pressure cylinder mechanism so that the indicator is in a predetermined positional relationship with the reference line during ridge shaping work, and causing the support body to pivot laterally about the vertical axis. A ridge shaping device featuring: 2. The support body is rotatable about the vertical axis with a first support frame mounted on one side of the earthmoving vehicle, and the support body is rotatable about the horizontal axis extending in the horizontal direction with a first support frame body attached to one side of the earthmoving vehicle. a second support frame attached to the first support frame; the hydraulic cylinder mechanism is interposed between the earthmoving vehicle and the first support frame; and the slope shaping blade is The ridge shaping device according to claim 1, which is attached to the second support frame. 3. The first support frame is attached to one end of the working blade of the earthmoving vehicle so as to be able to pivot about the vertical axis.
The ridge shaping device described in . 4. The upper surface shaping blade is attached to the inclined surface shaping blade so that its position can be freely adjusted along the cutting edge of the inclined surface shaping blade.
