A turntable 28 is provided on the outer wall of the nut pair 27. The rotation of the turntable 28 can drive the nut pair 27 to rotate. The nut pair 27 drives the lead screw 24 to move inside the stirring rod 23.

[0027] Furthermore, the covering assembly 03 includes a fixing rod 31, with fixing blocks 32 fixedly installed at both ends of the fixing rod 31. A rotating roller 33 is connected to the outer wall of the fixing rod 31. The rotating roller 33 is connected to the fixing blocks 32 through a torsion spring 34. The torsion spring 34 provides elastic force. Under the elastic force of the torsion spring 34, the rotating roller 33 can rotate around the fixing rod 31, thereby rolling up the covering curtain 35. The covering curtain 35 is wrapped around the outer wall of the rotating roller 33 to ensure that the covering curtain 35 will not fall off as a whole during the process of pulling down the covering curtain 35. Protrusions 36 penetrate through the lower ends of the covering curtain 35, and the protrusions 36 can limit the covering curtain 35.

[0028] Furthermore, the servo motor 21 is fixedly connected to the fermentation tank body 01 to ensure the stability of the servo motor 21's position. The servo motor 21 provides power, and starting the servo motor 21 can drive the drive rod 22 to rotate. The drive rod 22 is rotatably connected to the fermentation tank body 01 to ensure that the fermentation tank body 01 does not affect the rotation of the drive rod 22. The rotation of the drive rod 22 can drive the stirring rod 23 to rotate. The stirring rod 23 is fixedly connected to the drive rod 22 to ensure that when the drive rod 22 rotates, it can drive the stirring rod 23 to rotate, thereby stirring the material inside the fermentation tank body 01.

[0029] Furthermore, both the lead screw 24 and the guide block 25 are slidably connected to the stirring rod 23. The guide block 25 plays a guiding role. The turntable 28 is fixedly connected to the nut pair 27, ensuring that the turntable 28 can drive the nut pair 27 to rotate when it rotates. The nut pair 27 drives the lead screw 24 to move within the stirring rod 23.

[0030] Furthermore, the turntable 28 is rotatably connected to the stirring rod 23, ensuring that the stirring rod 23 does not affect the rotation of the turntable 28. The rotation of the turntable 28 can drive the nut pair 27 to rotate, and the nut pair 27 drives the lead screw 24 to move within the stirring rod 23. The fixing block 32 is fixedly connected to the fermentation tank body 01, ensuring the firmness of the fixing block 32 position.

[0031] Furthermore, the rotating roller 33 is rotatably connected to the fixed rod 31, and the two ends of the torsion spring 34 are fixedly connected to the fixed block 32 and the rotating roller 33 respectively. The torsion spring 34 provides elastic force. Under the action of the elastic force of the torsion spring 34, the rotating roller 33 can rotate around the fixed rod 31, thereby rolling up the covering curtain 35, which is convenient for rolling up the covering curtain 35.

[0032] Furthermore, the protrusion 36 is fixedly connected to the fermentation tank body 01 to ensure the firmness of the position of the protrusion 36. The end of the covering curtain 35 away from the protrusion 36 is fixedly connected to the rotating roller 33 to ensure that the covering curtain 35 will not fall off as a whole during the process of pulling down the covering curtain 35.

[0033] Working Principle: In operation, first rotate the turntable 28. The turntable 28 drives the nut assembly 27 to rotate, which in turn drives the lead screw 24 to move towards the scraper 26. The lead screw 24 then moves the scraper 26, causing it to adhere tightly to the inner wall of the fermentation tank body 01. Subsequently, when the servo motor 21 is started, it drives the drive rod 22 and the stirring rod 23 to rotate, allowing the scraper 26 to scrape off the material adhering to the inner wall of the fermentation tank body 01. Hold one end of the covering curtain 35 and pull it downwards. The covering curtain 35 drives the rotating roller 33 to rotate around the fixed rod 31, allowing the lower end of the covering curtain 35 to be fitted over the protrusion 36, thus limiting its position. The covering curtain 35 then covers the observation window of the fermentation tank body 01. The above describes the complete working principle of this utility model.
