The driving device 1 can be a motor; the second stirring rod 3 is in a cylindrical shape, and its inner diameter is larger than that of the first stirring rod 2; in other preferred embodiments, a sealing device such as a slip ring can be provided on the inner ring at the upper end of the second stirring rod 3 to prevent the material from entering the transmission component 4 through the gap between the first stirring rod 2 and the second stirring rod 3 during stirring, thereby damaging the transmission component 4.

[0023] The transmission component 4 includes a first transmission shaft 41 connected to the second stirring rod 3 and sleeved on the driving shaft 11, and a first gear 44 connected to the driving shaft 11; an internal gear 42 is provided inside the first transmission shaft 41, and the internal gear 42 is connected to the first gear 44 through a second gear 43. A first flange 411 is provided at one end of the first transmission shaft 41 away from the second stirring rod 3, and a second transmission shaft 412 is provided on the first flange 411, and the second gear 43 is sleeved on the second transmission shaft 412. Among them, the outer edge of the first flange 411 extends towards the end away from the first stirring rod 2 to form a fixing ring 413, and the internal gear 42 is embedded in the fixing ring 413.

[0024] A second flange 12 is connected to the driving device 1, and a cylindrical first bracket 13 is fixedly connected to the second flange 12. One end of the first bracket 13 away from the driving device 1 extends towards the inner circle to form a first support ring 131, and the outer circle of the fixing ring 413 is connected to the inner circle of the first support ring 131 through a bearing. It plays a supporting role for the transmission component 4, and further plays a supporting role for the second stirring rod 3 to prevent the second stirring rod 3 from deflecting during stirring.
