The bottom plate of the fermentation tank 1 is provided with a first drainage tank 6 communicating with the outside, and the first drainage tank 6 protrudes downward from the fermentation tank 1.

[0030] Specifically, the stirring device includes a stirring shaft 12 that passes through the side wall and is in transmission connection with an external stirring motor 5. A plurality of groups of stirring blades 13 are arranged on the stirring shaft 12, and the plurality of groups of stirring blades 13 are uniformly arranged along the axial direction of the stirring shaft 12. The power of the stirring motor 5 can be controlled by a regulator to adjust the speed and frequency of stirring according to experimental needs. The installation height of the stirring shaft 12 is designed according to the amount of fermentation materials in the experiment. Usually, the fermentation materials need to completely cover the stirring device, and generally, the stirring shaft 12 is arranged at one - third of the height of the fermentation tank 1.

[0031] During the organic fertilizer fermentation process, it is necessary to perform turning - pile treatment on it to make the internal and external fermentation speeds consistent. The design of the stirring device can be opened when turning - pile is needed and closed after turning - pile is completed.

[0032] A ventilation device is arranged on the side wall of the fermentation tank 1. Conventional fans, exhaust fans, ventilation fans, etc. in the prior art can be used and are uniformly arranged at the upper part of the side wall. A vent door that can be opened and closed is arranged inside the side wall corresponding to the ventilation device. It can be opened when ventilation is needed and closed and sealed when ventilation is not needed.

[0033] The fermentation tank 1 is equipped with an organic fertilizer determination thermometer with an external display screen. Temperature is a key parameter for monitoring the microbial decomposition process of organic fertilizer. By monitoring the temperature, the fermentation process of organic fertilizer can be monitored, the moisture content during the organic fertilizer fermentation process can be monitored, the degree of maturity of the organic fertilizer can be determined, and the turning - pile time and the termination fermentation time of the organic fertilizer can be determined. Therefore, this parameter needs to be monitored and recorded at any time. During the experiment, the organic fertilizer determination thermometer is inserted into the temperature detection hole 11 that matches it and fixed, and then the temperature changes at different heights during the organic fertilizer fermentation process, such as the temperatures of the upper, middle, and lower layers, can be directly observed and recorded from the outside.

[0034] The hole plug is used to seal the temperature detection hole 11 with a plug after pulling out the thermometer when turning - pile of the organic fertilizer is needed. The hole plug is preferably a rubber plug.

[0035] The function of the first liquid drainage tank 6 provided on the bottom plate is that during the fermentation process, the coarse straw can be spread on the bottom, and the fermentation materials are piled above the straw.
