[0025] like Figure 1-5As shown, the stirring structure 32 includes a fixing ring 323 fixedly connected to the inner top wall of the tank body 1, a connecting ring 321 fixedly connected to the inner top wall of the tank body 1 is arranged on the inner side of the fixing ring 323, a slideway is formed between the fixing ring 323 and the connecting ring 321, a toothed ring 322 located inside the slideway is fixedly connected to the surface of the fixing ring 323, and the stirring structure 32 also includes a mounting ring 325 arranged inside the tank body 1 and below the fixing ring 323, and evenly distributed connecting blocks 324 are fixedly connected to the inner side of the mounting ring 325, and the other end of the connecting block 324 is connected to the driving The surface of the moving shaft 201 is fixedly connected, and the inner wall of the mounting ring 325 is rotatably connected with four evenly distributed connecting shafts 326, the upper end of the connecting shaft 326 passes through the mounting ring 325 and is fixedly connected with a gear 3213 meshing with the gear ring 322, and the lower end of the connecting shaft 326 passes through the mounting ring 325, the area of ​​the mounting ring 325 is larger than the opening area of ​​the slideway, and the top of the mounting ring 325 blocks the slideway, and the setting of the mounting ring 325 blocking the slideway can prevent the raw material from entering the interior of the slideway and affecting the meshing of the gear 3213 and the gear ring 322;

[0026] When the motor 2 drives the drive shaft 201 to rotate, the mounting ring 325 can be driven to rotate synchronously through the connecting block 324. In this process, the connecting shaft 326 is driven to rotate through the mounting ring 325. The gear ring 322 and the gear 3213 cooperate with each other to drive the connecting shaft 326 to rotate.
