[0023] The lifting mechanism includes a fixing rod 15 symmetrically fixed at both ends of the bottom of the barrel cover 3. The fixing rod 15 is a hollow structure, and a threaded groove is opened at the lower end of the fixing rod 15. The thread in the threaded groove is matched with a screw rod 16. A driving motor is fixedly installed on the support seat 1. The output shaft of the driving motor is transmission-connected with the screw rod 16. The driving motor drives the screw rod 16 to rotate, and then the fixing rod 15 is lifted and lowered along the screw rod 16 through the threaded groove, thereby realizing the lifting and lowering of the barrel cover 3.

[0024] A stop block 17 is fixedly provided at the upper end of the screw rod 16 . The diameter of the stop block 17 is larger than the diameter of the thread groove. The setting of the stop block can prevent the screw rod 16 from being separated from the fixing rod 15 .

[0028] Working principle: When the stirring device is in use, the lifting mechanism first controls the barrel cover 3 to rise, and the raw materials are added into the stirring barrel 2. Then the barrel cover 3 is controlled to descend to close the stirring barrel 2, and the stirring motor is started. The stirring motor drives the stirring shaft 4 to rotate, and then drives the multiple stirring rods 5 and the scraper plate 9 fixedly connected thereto to rotate, stirring the materials. At the same time, the materials adhering to the barrel wall can be scraped off and stirring can be continued, thereby ensuring the material mixing effect;

[0029] When it is necessary to replace the stirring rod 5, cross bar 6 and scraper plate 9, the lifting mechanism controls the cylinder cover to rise again, so that the stirring components are exposed to the outside of the mixing barrel 2. The fasteners are removed, and the corresponding stirring rod 5 and cross bar 6 can be removed. The moving block 11 is pushed to overcome the elastic resistance of the reset spring 14 to slide, driving the card block 12 to exit the slot 10, and the limit on the fixed block 8 is released, and the scraper plate 9 can be removed. During installation, the moving block 11 pushes the card block 12 to be firmly stuck in the slot 10 under the elastic recovery action of the reset spring 14, thereby realizing the fixed connection between the scraper plate 9 and the cross bar 6, and the disassembly and assembly are convenient.

[0030] While ensuring the stirring effect of the stirring components on the materials, the utility model drives the barrel cover 3 to rise through the lifting mechanism, so that each stirring component is exposed to the outside of the stirring barrel 2. By removing the fasteners, the corresponding stirring rod 5 and cross bar 6 can be removed, and then the clamping block 12 is driven to exit the clamping groove 10 by pushing the moving block 11, and the limit on the fixed block 8 is released, and the scraper plate 9 can be removed, thereby ensuring the strength during connection and facilitating disassembly for cleaning, maintenance and replacement.
