A driving component for rotating the rotating shaft 7 is provided on the top of the stirring shaft 4, so that the toggling bar 6 can realize self-rotation in the process of rotating around the stirring shaft 4. A sliding mouth 16 is opened on one side of the stirring shaft 4, and a sliding seat 15 is slidably connected in the sliding mouth 16. A plurality of stirring rods 12 are connected to one side of the sliding seat 15 in rotation from top to bottom. The stirring shaft 4 rotates and drives the sliding seat 15 and the stirring rod 12 to rotate. The stirring rod 12 stirs the raw materials for the second time. A lifting component for moving the sliding seat 15 up and down is provided in the mixing barrel 1.

[0021] In the utility model, the driving assembly includes a gear 8 and a rack 9. The circumferential outer wall of the rotating shaft 7 is keyed to the gear 8. The top of the stirring shaft 4 is fixed with a fixing block 10 by bolts. The fixing block 10 is fixed with an electric push rod 11 by bolts. One end of the electric push rod 11 is fixed with a rack 9 by bolts, and the rack 9 is meshed with each gear 8. The electric push rod 11 reciprocates and extends to make the rack 9 move up and down, and the up and down movement of the rack 9 makes the gear 8 reciprocate, thereby making the rotating shaft 7 drive the toggle bar 6 to rotate in the process of rotating around the stirring shaft 4, so that the raw materials can be more dispersed.

[0022] In the utility model, the lifting assembly includes an inclined block 14 and a push rod 13.

[0026] The stirring shaft 4 rotates, driving the slide 15 and the stirring rod 12 to rotate. The stirring rod 12 stirs the raw materials again, and the push rod 13 rotates around the inclined block 14 during the rotation of the slide 15. Since the inclined block 14 is sloped, the push rod 13 drives the slide 15 to move upward during the rotation, and the spring 17 contracts under the force. When the push rod 13 rotates to the lower end of the inclined block 14, the spring 17 rebounds and resets. Such a cycle can make the slide 15 move up and down along the sliding mouth 16 during the rotation around the stirring shaft 4, and then the stirring rod 12 moves up and down to stir the raw materials at different heights in the mixing barrel 1, so that the stirring is more comprehensive.
