[0023] The outer walls of the two rotating shafts 9 are fixedly mounted with multiple stirring rods 12 through mounting sleeves 11. The upper end surface of the cover plate 6 is fixedly mounted with a first motor 14 through a supporting mechanism. The supporting mechanism includes a supporting plate 13 fixedly mounted on the upper end surface of the cover plate 6. The first motor 14 is fixedly mounted on the upper end surface of the support plate 13. The outer wall of the output shaft of the first motor 14 is connected to the connecting pipe 7 through a transmission mechanism. The transmission mechanism includes a pulley 15 fixedly mounted on the connecting pipe 7 and the outer wall of the output shaft of the first motor 14. The two pulleys 15 are connected for transmission through a belt.

[0024] A screw 17 is rotatably installed on the upper end surface of the cover plate 6 through the lifting frame 16, and a second motor 18 connected to the screw 17 is fixedly installed on the upper end surface of the lifting frame 16. A movable sleeve 20 is threadedly installed on the outer wall of the screw 17. A limit rod 19 is fixedly installed inside the lifting frame 16, and the limit rod 19 slides through the movable sleeve 20. The limit rod 19 can limit the movable sleeve 20 so that the movable sleeve 20 can only move axially along the outer wall of the screw 17.
