Claims

[Scope of utility model registration request]

In an excavating/transplanting machine configured by tiltably attaching a digging tool 3 to the tip of a boom 2 that is installed on a vehicle body 1 so as to be vertically swingable and horizontally rotatable, the digging tool 3 is configured to include: a semicircular arc-shaped support frame 4 whose central rear portion is pivoted to the tip of the boom 2 so as to be movable up and down;
and a horizontal mounting shaft 5 formed in a semicircular arc shape along the inside of the support frame 4 and extending outward from both front ends.
A blade 6 is mounted on both arms of the support frame 4 so as to be vertically movable, and a pinion gear 7 is attached to the mounting shaft 5, and a rack 8 is provided to mesh with the gear 7. A hydraulic cylinder 9 is installed between the rack 8 and the boom 2 or support frame 4.
A blade drive structure for an excavator/transplant machine, characterized in that the blade 6 is rotatably driven by the movement of the rack 8 by a hydraulic cylinder 9.
