The grooved wheel 8 is connected to the swing arm 9 via a chain. By designing the grooved wheel 8, the overall structure of the swing arm 9 can be reinforced with auxiliary support. The right end of the lifting box 7 is provided with a swing arm 9. A stirring shaft rotary motor 10 is fixedly installed on the swing arm 9. The output end of the stirring shaft rotary motor 10 is fixedly connected to a pulley 12. A belt 11 is sleeved on the outer side of the pulley 12. Another pulley 12 is sleeved on the inner side of the other end of the belt 11. The lower end of the pulley 12 is fixedly installed with a main shaft 14. A bearing chamber 13 is rotatably sleeved on the outer side of the main shaft 14 via a bearing. A protective cover 15 is rotatably sleeved on the outer side of the main shaft 14 via a bearing.

By designing the heat dissipation plate 16, the main shaft 14 can be cooled with auxiliary heat dissipation.

[0021] Please see Figure 1 , Figure 2 A coupling 17 is fixedly installed at the bottom of the main shaft 14, and a graphite sleeve 18 is fixedly installed on the outside of the stirring shaft. The graphite sleeve 18 is designed to protect the stirring shaft. The stirring shaft is fixedly installed at the bottom of the coupling 17, and an impeller 19 is fixedly installed on the outside of the stirring shaft.
