Claims

[Scope of utility model registration request]

A hollow shaft that can be inserted into the tip nozzle of a mud gun, a drill provided at the tip of this hollow shaft, and a base pivoted to the hollow shaft behind this drill so that the cutting edge can freely protrude from the outer periphery of the hollow shaft. A cutter, a cutter diameter variable drive device provided at the rear end of the hollow shaft, and a link and an interlocking rod that connect the cutter and the cutter diameter variable drive device so that the cutting edge of the cutter is shaped like a circular shape (circle diameter variable link and interlocking rod). A mud gun tip nozzle residual mud removal device comprising: a rotary drive device that rotates the hollow shaft; and a forward and backward drive device that moves the hollow shaft forward and backward.
