The implementation principle of the feeding machine for concrete processing in the embodiment of the application is as follows: the driving motor 112 drives the rotating shaft 11 to rotate, so that the rotating shaft 11 drives the helical blade 111 to transmit, at this time, the threaded lead screw 133 can drive the moving rod 13 to move along the length direction of the rod body 139, in order to drive the connecting rod 15 to be suitable for the abutting plates 161 which are in abutting contact with two surfaces of different positions and are opposite to the helical blade 111, the driving motor 112 drives the rotating shaft 11 to rotate, so that the rotating shaft 11 drives the helical blade 111 to transmit, at the same time, the moving motor 134 drives the threaded lead screw 133 to rotate, so that the moving rod 13 drives the abutting plates 161 to move along the length direction of the rod body 139, so that the abutting plates 161 at two sides move along the length direction of the helical blade 111, the abutting plates 161 at two sides can drive the sleeve 152 to be located on the fixed rod 151 to resist the elastic force of the spring 153 to move while moving, meanwhile, the reciprocating cylinder 137 drives the reciprocating plate 138 to move, so that the reciprocating plate 138 drives the inserting rod 136 to be located in the fixed cylinder 135 to move, the inserting rod 136 drives the abutting plates 161 to move on the helical blades 111 in a reciprocating mode, so that the abutting plates 161 on the two sides scrape off impurities adhered to the helical blades 111, manual cleaning is not needed, and manpower is saved; after the use, the worm 143 is driven to rotate by the rotating motor 144, so that the worm wheel 142 drives the hinge shaft 141 to rotate, and the moving rod 13 can drive the abutting plate 161 to rotate out of the casing 1, thereby preventing the abutting plate 161 from affecting the use of the helical blade 111.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
