Abrégé

Provided in the present specification is an automatic muzzle cleaning apparatus enabling a brush or nonwoven fabrics, which are used to clean a muzzle, to be rapidly detached therefrom. According to one embodiment of the present specification, the automatic muzzle cleaning apparatus includes a cleaning tool formed so as to rotate by coming in contact with the inner surface of the muzzle, while moving forward along the inner surface of the muzzle by means of a driving part formed inside a main body, wherein the cleaning tool comprises: an internal gear having cleaning tool grooves, which are recessed from the outer surface thereof toward the center thereof so as to connect the front and rear thereof, and are arranged to be spaced apart, with predetermined gaps therebetween, along the outer surface thereof; a connector inserted in one side of the cleaning tool groove and having catching protrusions formed at both sides thereof; a cleaning part inserted from the front of the connector toward the rear thereof, and detachably coupled thereto; a fixing part pressing the upper parts of the catching protrusions and coupled to the internal gear; and a combining part of which one end is coupled to the front surface of the internal gear so as to be rotatable and of which the other end rotates around one end thereof, and thus, according to the rotational direction, the front of the connector is covered or the front of the connector is opened.

Abrégé

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.

Abrégé

The multistage muzzle chamber cleaning apparatus according to the present invention includes: a rotating member which has a power supply unit formed therein and a motor which is rotated by receiving the power supplied by the power supply unit; a rotating body which is rotated in conjunction with the motor; a cleaning member which is configured to have an oblique cleaning unit which is obliquely coupled to the outer circumferential front portion of the rotating body and a parallel cleaning unit, both ends of which are coupled in parallel to the outer circumferential rear portion of the rotating body; and a handle member which is formed in the rear portion of the rotating member such that the length thereof can be adjusted telescopically. According to the present invention, the chamber cleaning device is transported within a narrow space such that the inside of the chamber can be cleaned with improved convenience. Also, durability can be increased since an oblique portion and a parallel portion in the chamber are cleaned well. Further, a cleaning solution can be sprayed without using any additional members. In addition, brushes can be quickly interchanged to facilitate user access.
