Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural waste treatment, and in particular to an animal manure fermentation device and a fermentation method. BACKGROUND

[0002] In the process of livestock breeding, a large amount of animal manure will be produced. If it is directly discharged without treatment, it will not only cause serious pollution to soil, water and air, but also breed bacteria and pests, affecting the surrounding environmental hygiene and the biological safety of the breeding farm. In order to realize the harmless and resource utilization of livestock and poultry manure, fermentation technology is usually used to convert manure into organic fertilizer.

[0003] In the actual implementation process, there are still some problems:

[0004] 1. In the material discharging link of the existing animal manure fermentation device, the material in the storage box is usually discharged directly or conveyed simply to the crushing device or the fermentation tank. Since there is a lack of stable and quantitative control mechanism, the supply amount of the material is prone to fluctuation, which reduces the uniformity of the subsequent crushing process and the fermentation process, and affects the fermentation quality. In addition, some devices have the problem of bidirectional transmission in the discharging structure. Furthermore, the capacity adjustment function of the existing discharging mechanism is relatively single, and the single discharging amount cannot be flexibly changed according to different fermentation requirements, which reduces the adaptability and stability of the device.

[0005] 2. In the process of conveying the material to the crushing device, the existing animal manure fermentation device usually adopts screw conveying or belt conveying. Since most of these conveying methods are continuous conveying, they lack precise coordination with the discharging rhythm, which easily causes accumulation at the feeding port or insufficient supply, thereby affecting the crushing efficiency and stability. In addition, at the position of the crushing device or the discharging port, the material is prone to adhere to the feeding channel or the entrance of the crushing cavity due to high humidity and strong adhesion, which forms accumulation and blockage. The existing technology relies on manual knocking or vibration device for unblocking, which not only increases the labor intensity, but also may cause equipment damage due to improper operation. In addition, some anti-blocking mechanisms need an additional power source to drive. SUMMARY

moves, the knocking block 307 will be in contact with the extrusion block 301 on the outer wall of the smashing device 5 and the material storage box 6 and be compressed, so that the return spring 322 stores energy, when the knocking block 307 is separated from the extrusion block 301, the return spring 322 releases the elastic force, drives the knocking block 307 to knock on the outer side wall of the material storage box 6 and the smashing device 5, so as to prevent the material from being accumulated and blocked at the discharge port or the smashing inlet, after the smashing device 5 receives the animal excrement pushed into by the push plate 317, the animal excrement is smashed into relatively uniform particles, providing suitable raw materials for the subsequent fermentation process, thereby, the motor 7 drives the lead screw 311, the lead screw 311 drives the sliding support 305, the sliding support 305 drives the rack 315, the rack 315 drives the gear 314, the gear 314 drives the quantitative cylinder 310 through the one-way clutch 316 to realize the discharging; at the same time, the rotation of the quantitative cylinder 310 drives the auxiliary fermentation mechanism 9 to operate, so that the compressed gas of the sealed gas tank 910 pushes the fermentation liquid to be sprayed on the surface of the excrement, improving the fermentation effect; then the push plate 317 sends the material into the smashing device 5 for smashing treatment, and the anti-blocking function is realized by cooperating with the knocking assembly, so as to ensure that the device can still maintain stability and high efficiency under long-time operation.
