During disassembly, only the pair of connecting bolts 305 needs to be removed, and then one side of the pair of clamping plates 302 of the stirring member 301 can be separated from the stirring shaft 300. Compared to conventional feces fermentation tanks, the present invention no longer welds the stirring members 301 to the stirring shaft 300, but instead uses a detachable connection. If the stirring blades 304 of one of the stirring members 301 are damaged, only that stirring member 301 needs to be replaced. The present invention solves the problems of difficulty in installation and disassembly of the current feces fermentation tank during use and the high cost of replacing the stirring shaft and all stirring blades after the stirring blades are damaged.
