The motor 8 is started, and the motor 8 drives the first rotating shaft 12 to rotate, the first rotating shaft 12 drives the rotating plate 10 to rotate, and the rotating plate 10 drives the two second rotating shafts 15 to revolve.

[0028] In one embodiment, Figure 5 As shown, a gear ring 13 is fixedly connected to the top wall of the mixing barrel 1, and two second rotating shafts 15 are rotatably connected to the rotating plate 10 through bearings, and a gear 9 is fixedly connected to the top of the second rotating shaft 15, and the gear 9 is meshed with the gear ring 13. During the revolution of the second rotating shaft 15, the gear 9 is meshed with the gear ring 13, so that the gear 9 rotates, and the rotation of the gear 9 drives the second rotating shaft 15 to rotate, and the second rotating shaft 15 drives the stirring rod 16 to rotate, so that the stirring rod 16 rotates during the revolution, thereby improving the stirring effect of the instrument, saving stirring time, and improving stirring efficiency.

[0029] In one embodiment, Figure 3 and Figure 5 As shown, one end of the first rotating shaft 12 located in the mixing barrel 1 is fixedly connected with a screw rod 14. When the first rotating shaft 12 rotates, the first rotating shaft 12 drives the screw rod 14 to rotate.

[0033] Example 2

[0034] In one embodiment, Figure 1 As shown, the motor 8 is connected to the first rotating shaft 12 via a reducer. The motor 8 is equipped with a reducer to increase the torque. When the load is large, it is not cost-effective to simply increase the power of the motor 8.
