The invention includes a mounting frame, a row of rotary cutting high-pressure heads mounted on the mounting frame, the rotary cutting high-pressure heads are conical in structure, a number of teeth are mounted on the outer wall of the rotary cutting high-pressure head, a number of high-pressure flushing pipes are mounted inside the rotary cutting high-pressure head, and the open ends of the high-pressure flushing pipes are exposed to the outer wall of the rotary cutting high-pressure head.
