[0002] A large amount of byproducts - livestock and poultry manure - will be produced in the process of livestock and poultry breeding. If a large amount of livestock and poultry manure is not effectively treated, it will cause serious environmental pollution. In the prior art, fermentation tanks have been widely used in the treatment of livestock and poultry manure because of their advantages of short fermentation time (8-10 days), high treatment efficiency, centralized gas collection and treatment, good discharging effect, no climate impact and small footprint. However, the solid manure residue produced by the solid-liquid separation of livestock and poultry manure needs to be transported by a shovel truck. After the fermentation is completed, the discharging of the fermentation tank also requires a shovel truck. In the prior art, the treatment of livestock and poultry manure has a low degree of automation in the treatment process, and a large number of shovel trucks are required to intervene in the manure transportation process, which is time-consuming and labor-intensive, and leakage problems are prone to occur during the transportation process.

[0006] A first conveying auger is arranged between the solid-liquid separation system and the material mixer. The first conveying auger conveys the manure in the collection bucket to the material mixer. The material mixer is used to fully mix and stir the solid manure with the added return materials and auxiliary materials.

[0007] The material mixer is connected to a scraper elevator, which is used to transport manure to a distribution auger. The distribution auger extends to the top of each fermentation tank. The distribution auger is used to evenly put the manure transported by the scraper elevator into each fermentation tank.

[0008] Furthermore, the livestock and poultry manure collection, transportation and processing system also includes a storage bin, and a second conveying auger connected to the discharge port of the fermentation tank is arranged on the side of the fermentation tank. The second conveying auger diverts the fermented manure, and transports part of it to the storage bin for secondary aging, and the other part is transported to the material mixer as recycled material.

[0009] Furthermore, the solid-liquid separation system specifically includes a filter press, a solid-liquid separator and a sewage treatment device, and the collecting bucket is arranged below the filter press and the solid-liquid separator;

[0010] The solid-liquid separator is used to separate the solid and liquid in feces. The sewage generated by the solid-liquid separator is fed into the sewage treatment equipment. The sludge generated by the sewage treatment equipment is fed into the filter press for filtration treatment. The mud cake generated by the filter press and the feces residue generated by the solid-liquid separation fall into the collection bucket below the filter press.

[0011] Furthermore, a first metering device is provided at the upper outlet of the material mixer, and the first metering device is used to detect and control the discharge amount of the material mixer;
