The scraping rod 24 is detachably connected to the push rod 23, and the scraping rod 24 can resist the inner wall of the mixing barrel 10 and scrape and clean the inner wall of the mixing barrel 10. The stirring shaft 20 is rotatably connected to the top of the mixing barrel 10 and extends into the cavity of the mixing barrel 10, and the two cross bars 21 are fixedly connected to the stirring shaft 20. The two cross bars 21 are respectively installed at positions close to the top and bottom surfaces of the mixing barrel 10, and the pushing plate 22 forms a spiral folded plate structure. The upper and lower ends of the pushing plate 22 are respectively fixedly connected to the two cross bars 21. In the case, two cross bars 21 are provided, and a spiral pushing plate 22 is provided between the two cross bars 21. A motor connected to a power source is fixedly installed on the top surface of the mixing barrel 10. The stirring shaft 20 is connected to the output shaft of the motor. The pushing plate 22 is driven to rotate by the rotation of the stirring shaft 20. The spiral pushing plate 22 is used to flip the raw materials in the mixing barrel 10. The pushing plate 22 can flip the bottom material toward the top and promote the mutual extrusion of the materials to improve the mixing effect. The cross bar 21 below can push the material, so that the material is driven toward the port of the discharge pipe 12 in the discharge stage to promote the discharge. The push rod 23 elastically connected to the cross bar 21 can push the scraping rod 24 to approach the inner wall of the mixing barrel 10. With the circular motion of the cross bar 21, the inner wall of the mixing barrel 10 is scraped and cleaned to reduce the residue on the inner wall of the mixing barrel 10. The mixing barrel 10 has the characteristics of good mixing effect, thorough discharge and less scaling on the inner wall of the mixing barrel 10.

The push rod 23 is elastically connected to the cross bar 21 through the sliding rod 31. The sliding rod 31 forms a rod body structure adapted to the slide groove. An elastic member is provided in the slide groove. The elastic member includes but is not limited to a spring. The end of the sliding rod 31 is connected to the elastic member, and the other end of the sliding rod 31 is fixedly connected to the push rod 23.

A motor connected to a power supply is fixedly installed on the top surface of the mixing barrel 10. The stirring shaft 20 is connected to the output shaft of the motor. The extrusion and pushing plate 22 is driven to rotate by the rotation of the stirring shaft 20. The raw materials in the mixing barrel 10 are turned over by the spiral extrusion and pushing plate 22. The extrusion and pushing plate 22 can turn the bottom material toward the top and promote the mutual extrusion of the materials to achieve the mixing of the raw materials. The elastic member takes a spring as an example, and the elastic force of the spring is used to push the sliding rod 31 to slide in the slide groove, thereby realizing the elastic connection between the push rod 23 and the cross bar 21. It can ensure that the scraping rod 24 is in full contact with the inner wall of the mixing barrel 10, and the push rod 23 can push the scraping rod 24 to contact the inner wall of the mixing barrel 10.
