[0029] When the present embodiment is working, the rotation of the No. 1 air outlet pipe 48 drives the connecting rod 54 to rotate, and the rotation of the connecting rod 54 drives the stirring rod 53 to rotate, stirring the organic fertilizer inside the fermentation tank 1, so that the microorganisms are evenly distributed in the organic fertilizer, and can fully contact and utilize the organic matter, thereby improving the fermentation efficiency. At the same time, the rotation of the hollow tube 47 drives the No. 1 sliding ring 51 to move up and down through the No. 1 reciprocating thread groove, and the No. 1 sliding ring 51 moves up and down to drive the No. 2 rotating ring 56 to move up and down, and the No. 2 rotating ring 56 moves up and down to drive the stirring rod 53 to move up and down, so as to better stir the organic fertilizer inside the fermentation tank 1 and improve the fermentation efficiency.

[0030] When the organic fertilizer is fermenting, harmful gases will be generated inside the fermentation tank 1. The increase in harmful gases will cause the pressure inside the fermentation tank 1 to be too high. When the pressure inside the fermentation tank 1 is too high, the gas will squeeze the pressure relief disk 63, and the pressure relief disk 63 will move upward under the squeezing. After the pressure relief disk 63 moves upward for a distance, the gas is discharged through the H-shaped pipe 61 to prevent the gas pressure inside the fermentation tank 1 from being too high and damaging the equipment. When the harmful gas is discharged through the H-shaped pipe 61, it contacts the activated carbon plate 65. The activated carbon plate 65 purifies the harmful gas to prevent the harmful gas from being discharged into the atmosphere and polluting the surrounding environment. At the same time, when the pressure relief disk 63 moves upward, it disengages from the limit rod 62. After the limit rod 62 disengages from the pressure relief disk 63, it is moved away from the vertical rod 67 by the elastic force of the No. 1 spring. The limit rod 62 moves in the direction away from the vertical rod 67 to release the limit on the vertical rod 67. After the vertical rod 67 is released from the limit, the activated carbon plate 65 moves downward through the elastic force of the No. 3 spring. The activated carbon plate 65 moves downward to drive the vertical rod 67 to move downward. The vertical rod 67 moves downward to drive the L-shaped rod 68 to move downward. After the L-shaped rod 68 moves downward for a distance, the cleaning ring 59 moves upward to contact and squeeze the L-shaped rod 68 to move upward. The L-shaped rod 68 moves upward to drive the vertical rod 67 to move upward. The vertical rod 67 moves upward to drive the activated carbon plate 65 to move upward, so that the activated carbon plate 65 moves up and down, increasing the contact area between the harmful gas and the activated carbon plate 65, better purifying the harmful gas, and preventing the harmful gas from being discharged into the atmosphere, causing pollution to the surrounding environment and harm to the staff.
