[0026] Working principle: organic waste is poured into the fermentation tank 11, enzyme probiotics are added, and the motor 31 is started. The output shaft of the motor 31 drives the rotating rod 32 and the stirring rod 33 to rotate, so that the organic waste and the enzyme probiotics can be turned over and mixed; at the same time, the rotating rod 32 drives the second support rod 422, the second scraper 421 and the support plate 431 to rotate synchronously, and the second scraper 421 can be used to scrape the inclined surface of the inner wall of the fermentation tank 11.

It can not only avoid the phenomenon that the fertilizer adheres to the inner wall surface of the fermentation tank 11 and is difficult to be discharged, resulting in a waste of fertilizer, but also can improve the mixing effect of the organic garbage and the fermentation agent in the inner cavity of the fermentation tank 11 during the mixing process.
