Claims

[Scope of utility model registration request]

A rotary shaft equipped with a rotary cutter at the tip and a screw-like dirt removal blade on the outer periphery is rotatably supported in an excavation drum with an enlarged tip, and a rotary shaft drive is attached to the rear end of the drum. The devices are connected, and a soil discharge port is provided on the front side thereof, and the drum and drive device are connected to each other.
It is installed on the base so that it can move forward and backward with a propulsion jack, and this propulsion jack consists of a monocylindrical cylinder and a telescopic cylinder connected in a straight line.
Furthermore, a reaction force receiving means is provided at the front end of the excavation drum.
An excavator characterized in that a telescopic cylinder is fixed to the rear end of a base and a positioning and fixing means is provided.
