[0034] More specifically, firstly, the raw materials are fed into the mixing tank 1 through the addition pipe 28 and the feed pipe. The spray ring 30 ensures uniform distribution of the feed. Then, the stirring motor 3 starts, driving the stirring shaft 4 and stirring blades 5 to rotate, and the materials begin to mix under stirring. At the same time, the scraper plate 7 scrapes away residual materials from the tank wall to ensure the mixing effect. During the stirring process, if the load is too large, the overload protection mechanism will be triggered to adjust the stirring load and avoid overload damage to the equipment. Finally, the mixed material can be discharged through the discharge pump 26 and the external pipe 27. The external pipe 27 is connected to external equipment to realize further processing or transportation of the material.

[0035] In summary, during the use or operation of the overall equipment: when the stirring and scraping mechanism is required, the stirring motor 3 drives the stirring shaft 4 to rotate, and the stirring blades 5 and the crossbeam 6 rotate accordingly, promoting the mixing of materials in the mixing tank 1.

The overload protection pipe 8 and the overload protection rod 9 will be linked together. When the external force is greater than the spring preload force, the extension frame 11 will disengage from the overload protection groove 10 and automatically adjust the load during the stirring process, thereby preventing damage to the stirring motor 3 or the stirring shaft 4.

[0037] When the spring adjustment mechanism is required, the directional sleeve 15 slides directionally on the outer wall of the overload protection tube 8. The adjustment ring 16 is linked with the directional sleeve 15 through the overload protection spring 14 to adjust the overload protection spring 14. The user can adjust the preload of the overload protection spring 14 by sliding the sliding sleeve and using the adjustment ring 16.

At the same time, the wall scraping plate 7 scrapes the residual material on the wall, ensuring the mixing effect, during the stirring process, if the load is too large, the anti-overload mechanism will trigger, adjusting the stirring load, avoiding overload damage to the equipment, finally, the mixed material can be discharged through the discharge pump 26 and the external pipe 27, the external pipe 27 is connected with external equipment, realizing further processing or transportation of the material.
