[0033] Embodiment 2

[0034] As Figures 1-4As shown, the transmission mechanism 2 includes a housing 21. The surface of the housing 21 is fixedly connected to one side of the inner wall of the mixing tank 11. The inner wall of the housing 21 is fixedly connected to the surface of the water pump 22. One end of the output shaft of the water pump 22 is fixedly connected to one end of the connecting pipe 23.

The added materials will flow into the mixing tank 11 through the transfer pipe 14. When the materials are added into the mixing tank 11, the staff can start the motor 18. When the motor 18 is started, its output shaft will drive the rotating rod 19. The rotating rod 19 will rotate by cooperating with the bearing 110. When the rotating rod 19 rotates, it will synchronously drive the fixed ring 112 and the stirring rod 114 to rotate. When the stirring rod 114 rotates, it will evenly mix the materials in the mixing tank 11. The baffle 15 and the sealing ring 16 can prevent the materials added into the mixing tank 11 from contacting the bearing 110. After the materials are mixed, the staff can start the water pump 22 and then turn the valve 24 to open it. The water pump 22 will send the materials in the mixing tank 11 out through the connecting pipe 23 for the staff to use.
