PURPOSE: To save the labor necessary for forcing mud into a tap hole by time- controlling various stages such as the stage of charging mud into a mud charge chamber from a slicer, and charging automatically mud into a mud gun.
CONSTITUTION: Mud is charged into a mud charge chamber 3 from a slicer 6 at the first stage. A piston 4 for pushing the mud which is supplied in the chamber 3 into the cylinder 1 of a mud gun is moved forward from the initial position at the second stage. The piston 4 is moved backward to the initial position at the third stage. The time necessary for said first stage, the timing of the start of the second stage, the time required for the forward stroke, and the time needed for the third stage are set to a timer 12. Then the presence or absence of a confirmative signal for the filling of mud is detected by a mud detecting plate 8 provided at the nozzle 2 of the mud gun. When said signal is absent, the stages from the first to the third stage are repeated. When the signal is present, the operation is stopped after the completion of the third stage.
