When the movable discharge shell moves to the bottom of the circular fermentation tank and the motor b is in operation, the fermented straw and excrement can be discharged through the left end of the movable discharge shell under the action of the spiral discharge rack.

[0027] In addition, the movable closing plate can slide outward a certain distance under the weight of the solid circular rod, creating a larger gap between the movable closing plate and the movable feeding hopper. This allows workers to pre-add straw and excrement materials, enabling simultaneous feeding and discharging of materials and reducing equipment downtime. When the movable feeding hopper rotates to directly above the circular fermentation tank, the straw and excrement materials in the hopper enter the tank. Simultaneously, the movable closing plate automatically resets under the action of three return springs, achieving automatic closure.

[0028] 2. When the operator connects the external high-pressure agent pipeline to the connector and opens the valve on the external agent pipeline, the liquid agent in the agent pipeline can enter the hollow shell and then be sprayed out through a row of inactivation holes, which plays an auxiliary role in inactivating microorganisms and bacteria in straw and excrement raw materials; the setting of a row of one-way valves ensures that the agent in the hollow shell will only be discharged when the external valve is opened.

[0029] In addition, the ultraviolet lamps help to inactivate the microorganisms and bacteria in the straw and excrement raw materials, preventing the complex microorganisms and bacteria in the straw and excrement raw materials from affecting the subsequent fermentation effect. After the microorganisms and bacteria in the straw and excrement raw materials are inactivated, the staff can use the motor to rotate the hollow shell half a turn, so that the ultraviolet lamp can be automatically removed from the circular fermentation tank.
