[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive a rotating shaft, which in turn drives a support shaft to rotate, thereby causing the auger blades to rotate. This allows the waste at the bottom of the fermentation tank to enter the cylinder from the feed inlet and then be transported to the discharge outlet by the auger blades, forming a cycle within the fermentation tank. This makes the mixing, crushing, and stirring of waste more efficient and complete.

[0014] 2. This utility model uses a motor to drive a guide block to rotate a slip ring, and a spring to compress the slip ring, which in turn causes a connecting rod to rotate a scraper to scrape the inner wall and outer side of the fermenter. This cleans and scrapes away the residue adhering to the inner wall and outer side of the fermenter, making subsequent cleaning of the fermenter's interior more convenient.
