[0023] The force-applying structure 15 includes a second motor 151, a cam 152, a push plate 153 and a spring 154. The second motor 151 is fixed to the right side of the top of the mixing barrel 1. The output shaft of the second motor 151 is fixed to one side of the cam 152. The push plate 153 is fixed to the top of the movable rod 14. The top surface of the push plate 153 is rotatably connected to a plurality of rollers 16. The surfaces of the rollers 16 are rollingly connected to the cam 152. In this way, the friction between the cam 152 and the push plate 153 can be reduced, so that the cam 152 can be pushed more conveniently. The spring 154 is set On the surface of the movable rod 14, the two ends of the spring 154 are respectively fixed between the push plate 153 and the top of the mixing barrel 1, so that when force is applied to the movable rod 14, the second motor 151 can be started and the cam 152 can be driven to rotate, so that the protruding part of the cam 152 rotates to the bottom, thereby applying force to push the push plate 153.

[0025] Scrapers 21 are fixedly connected to both sides of the bottom surface of the rotating rod 6, and the other side of the scraper 21 is in contact with the inner wall of the mixing barrel 1. As the rotating rod 6 rotates, the scraper 21 is driven to rotate together, thereby facilitating better mixing of the raw materials adhered to the bottom wall of the inner cavity of the mixing barrel 1.

[0026] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: When in use, the raw materials can be poured into the mixing barrel 1 through the feed hopper 4, and then the first motor 5 is started, and the rotating rod 6 is driven to rotate, and the movable sleeve 8 and the stirring rod 9 are driven to rotate together, so as to facilitate the mixing and stirring of the raw materials poured into the mixing barrel 1. During the stirring process, the movable rod 14 and the fixed plate 13 can be pushed downward by the force structure 15, and the movable sleeve 8 and the stirring rod 9 can be driven to move up and down reciprocatingly on the surface of the rotating rod 6, so as to better mix the raw materials inside the mixing barrel 1, thereby improving the mixing effect. After the mixing is completed, the solenoid valve 20 can be opened, and as the rotating rod 6 rotates, the auger 10 will be driven to rotate together, so as to facilitate the better discharge of the raw materials.
