[0021] It should be noted that when microorganisms need to be fermented, the staff places the microbial flora into the microbial fermentation cylinder 1 through the feed vertical pipe 2, and then inputs the nutrient solution required for microbial fermentation into the microbial fermentation cylinder 1 through the feed vertical pipe 2, starts the microbial fermentation cylinder 1, and the microbial fermentation cylinder 1 heats the microbial mixed solution so that the microorganisms start to ferment, and starts the drive motor 5. The drive motor 5 drives the stirring blade 14 to rotate through the transmission rod 6, the first transmission pulley 8, the transmission belt 9, the second pulley 10 and the rotating rod 11 to mix and stir the microbial flora and the nutrient solution, thereby increasing the microbial fermentation rate. At the same time, when the rotating rod 11 drives the stirring blade 14 to rotate, the stirring blade 14 drives the rotating friction plate 15 to rotate and generates heat through friction with the inside of the telescopic cylinder 13, which can preheat the inside of the microbial fermentation cylinder 1, quickly activate the microbial metabolic system, and further increase the fermentation rate of the microbial flora.

[0029] It should be noted that when the microorganisms inside the microbial fermentation cylinder 1 are fermented and discharged, the electric push rod 17 is started, and the electric push rod 17 drives the rotating cleaning brush 18 to move to the inner wall of the microbial fermentation cylinder 1. The driving motor 5 drives the rotating cleaning brush 18 through the transmission rod 6 and the electric push rod 17 to rotate and brush the inner wall of the microbial fermentation cylinder 1 to prevent microorganisms from adhering to the inner wall of the microbial fermentation cylinder 1, so that the staff does not need to use other equipment to clean.

[0031] It should be noted that when the rotating round rod 11 drives the stirring blade 14 to rotate, the sliding cleaning brush 22 is affected by the centrifugal force and moves toward the side of the rotating friction plate 15. When the sliding cleaning brush 22 moves to a certain position, the return spring 20 drives the sliding cleaning brush 22 to contract and reset through elastic force. This cycle continues, and the sliding cleaning brush 22 can brush the side wall of the stirring blade 14 to prevent microorganisms from adhering to the side wall of the stirring blade 14.

S2. When the rotating rod 11 drives the stirring blade 14 to rotate, the stirring blade 14 drives the rotating friction plate 15 to rotate and generates heat by friction with the inside of the telescopic cylinder 13, which can preheat the microbial mixture.

[0037] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0038] During operation, when microorganisms need to be fermented, the staff places the microbial flora into the microbial fermentation cylinder 1 through the feed vertical pipe 2, and then inputs the nutrient solution required for microbial fermentation into the microbial fermentation cylinder 1 through the feed vertical pipe 2, starts the microbial fermentation cylinder 1, and the microbial fermentation cylinder 1 heats the microbial mixed solution so that the microorganisms start to ferment, and starts the drive motor 5. The drive motor 5 drives the stirring blade 14 to rotate through the transmission rod 6, the first transmission pulley 8, the transmission belt 9, the second pulley 10 and the rotating rod 11 to mix and stir the microbial flora and the nutrient solution, thereby increasing the microbial fermentation rate. At the same time, when the rotating rod 11 drives the stirring blade 14 to rotate, the stirring blade 14 drives the rotating friction plate 15 to rotate and generates heat through friction with the inside of the telescopic cylinder 13, which can preheat the inside of the microbial fermentation cylinder 1, quickly activate the microbial metabolic system, and further increase the fermentation rate of the microbial flora. After the microbial fermentation is completed, the microbial mixed solution inside the microbial fermentation cylinder 1 is discharged through the discharge vertical pipe 24. With the help of the setting of the microbial filter box 26, the fermented microorganisms and the fermentation solution can be separated, which is convenient for the staff to subsequently recover the fermented microorganisms. The dustproof bin 3 can protect the drive motor 5 and prevent dust in the air from entering the drive motor 5 and causing damage to the drive motor 5. When the microbial fermentation inside the microbial fermentation cylinder 1 is completed, the ultraviolet sterilization lamp 4 is started to disinfect and sterilize the inner wall of the microbial fermentation cylinder 1 to prevent the residual fermentation liquid from breeding bacteria inside the microbial fermentation cylinder 1 after the microbial fermentation is completed; By providing a fixed buoy 16, the telescopic cylinder 13 is always floated above the surface of the fermentation liquid, preventing the telescopic cylinder 13 from entering the fermentation liquid and affecting the stirring efficiency of the stirring blade 14 on the fermentation liquid; When the microorganisms in the microbial fermentation cylinder 1 are fermented and discharged, the electric push rod 17 is started, and the electric push rod 17 drives the rotating cleaning brush 18 to move to the inner wall of the microbial fermentation cylinder 1. The driving motor 5 drives the rotating cleaning brush 18 to rotate through the transmission rod 6 and the electric push rod 17 to scrub the inner wall of the microbial fermentation cylinder 1 to prevent microorganisms from adhering to the inner wall of the microbial fermentation cylinder 1, so that the staff does not need to use other equipment for cleaning; When the rotating rod 11 drives the stirring blade 14 to rotate, the sliding cleaning brush 22 is affected by the centrifugal force and moves toward the side of the rotating friction plate 15. When the sliding cleaning brush 22 moves to a certain position, the return spring 20 drives the sliding cleaning brush 22 to retract and return to its original position through elastic force. In this cycle, the sliding cleaning brush 22 can scrub the side wall of the stirring blade 14 to prevent microorganisms from adhering to the side wall of the stirring blade 14. When microorganisms are fermenting inside the microbial fermentation cylinder 1, by providing a pH detection sensor 23, the staff can monitor the pH value inside the fermentation liquid in real time to prevent the pH value inside the fermentation liquid from becoming abnormal without the staff knowing, which ultimately leads to the failure of microbial fermentation. When the microbial mixture flows into the microbial filter box 26 through the discharge vertical pipe 24, the electric rotating rod 27 is started, and the electric rotating rod 27 drives the rotating vertical plate 29 to rotate through the rotating disc 28. When the rotating vertical plate 29 rotates, the fermentation liquid can be thrown out of the microbial filter box 26 by centrifugal force, thereby improving the equipment's separation efficiency of microorganisms and fermentation liquid.
