The two gears 5 mesh, allowing both rotating rods 3 and crushing rollers 4 to rotate simultaneously. The crushed raw materials are crushed by the two crushing rollers 4, and the crushed materials fall into the lower part of the crushing box 2. When adding raw materials to the fermentation cylinder 1, the electric push rod 9 is activated. The electric push rod 9 drives the sealing plate 10 to extend and retract within the mounting groove 8. When the sealing plate 10 retracts into the mounting groove 8, the feeding chute 7 opens, and the raw materials enter the fermentation cylinder 1 through the feeding cylinder 11. When it is necessary to pause feeding or adjust the crushing rate, the sealing plate 10 retracts from the mounting groove 8. The material feeding trough 7 extends out from the filling trough 8 to control the feeding. The second motor 12 is started to drive the stirring rod 13 to rotate. The stirring rod 13 drives the connecting rod 14, stirring blade 19 and the auxiliary scraping assembly below to rotate. The stirring blade 19 rotates in the fermentation tank 1, which can turn and mix the raw materials. At the same time, the connecting rod 14 drives the scraper seat 15 to move along the inner wall of the fermentation tank 1. The scraper 18 is pressed against the tank wall by the elasticity of the spring 17 to scrape off the adhering raw materials and prevent the raw materials from adhering to the inner wall of the fermentation tank 1. At the same time, the bottom of the stirring rod 13 drives the two connecting columns 20 and the scraper 21 to move. The scraper 21 cleans the raw materials adhering to the lower inner wall of the fermentation tank 1. The decomposed fertilizer is discharged through the discharge pipe 22 at the bottom of the fermentation tank 1.
