PURPOSE: A mud gun is provided to remove mud material, which is discharged from an outlet according to the backward movement of the piston of the mud gun, using a removing apparatus, thereby preventing the outlet from being clogged by the mud material. CONSTITUTION: A mud gun includes a body part, a piston, an inlet, at least one outlet(126), and a removing apparatus(200). The body part has a space housing a predetermined mud material. The piston moves a predetermined distance along inside the body part. The mud material is fed to the inlet at the body part by the forward movement of the piston. The mud material is discharged from the outlet at the body part by the backward movement of the piston. The removing apparatus removes the mud material discharged from the outlet. |
