<p>The present invention relates to an apparatus for automatically cleaning a muzzle, which is provided with a cleaning means coupled to a cylindrical body moved forward and backward in and out of a muzzle by means of transport rollers that are linked to a motor, for cleaning the inner surface of the muzzle in which a plurality of steel wires are formed. The present invention provides the apparatus for automatically cleaning a muzzle, of which the cleaning means comprises: a cylindrical pipe on which a plurality of insertion holes are formed along the circumference thereof; a rotary gear linked to the motor; and a cleaning member equipped with a rotary shaft inserted into the insertion hole, and a bevel gear, which is coupled to a bottom portion of the rotary shaft and is linked to the rotary gear, for rotating the cleaning member, wherein the insertion holes comprise a small hole of which the cross-sectional shape is a portion of a circle corresponding to the cross-section of the rotary shaft, and a big hole which communicates with the small hole in the horizontal direction and of which the cross-sectional shape is a portion of a circle that is bigger than the biggest cross-section of the lower portion of the rotary shaft, and wherein the apparatus for automatically cleaning a muzzle is provided with a fixing member for bringing the cleaning member into close contact with and fixing same to the small hole, when the cleaning member is fixed, wherein the fixing member does not hamper the cleaning member from being separated toward the outside of the cylindrical pipe through the big hole, when the fixing is released.</p> |
