[0002] The fecal treatment in livestock and poultry breeding is an important environmental protection issue, and scientific methods need to be adopted to reduce environmental pollution. Among them, the common treatment method is to turn feces into fertilizer. Livestock and poultry manure is a traditional organic fertilizer, which can be directly applied or composted. During the composting process, microorganisms act to mineralize, humify and harmlessize organic matter, turning it into a more fertile mature fertilizer. This process is also called fecal fermentation. In the prior art, the feces mixed with auxiliary materials are put into a closed container, and by controlling the temperature and humidity in the container, a suitable environment is provided for fecal fermentation. At the same time, ventilation needs to be paid attention to during the fermentation process. The fresh air contacts the feces through the ventilation holes opened on the surface of the container. However, the traditional ventilation mainly relies on the continuous stirring of the stirring component on the feces to change the position of the feces and contact with the fresh air. The flow trajectory of the fresh air in the fermentation device is uncertain, and it is easy to occur that the fresh air contacts the feces unevenly, affecting the fermentation quality.

[0021] Please refer to Figures 1-4 , this embodiment provides a technical solution: a fecal fermentation device, including a fecal fermentation tank 1 and a diversion and ventilation mechanism 4;

[0022] Fecal fermentation tank 1: An outlet pipe 3 is provided at the air outlet in the middle of the upper surface thereof.

A fence 6 is provided on the upper surface of the fecal fermentation tank 1 to provide protection for the edge of the upper surface of the fecal fermentation tank 1;

[0023] Diversion and ventilation mechanism 4: It includes an inner tube 41, an outer tube 42 and a baffle 44. The inner tube 41 is rotatably connected between the upper and lower inner walls of the fecal fermentation tank 1, and the inner tube 41 can move up and down. The outer tube 42 is arranged between the upper and lower inner walls of the fecal fermentation tank 1. Air holes are provided on the outer arc surfaces of both the inner tube 41 and the outer tube 42. Baffles 44 are respectively provided on the outer arc surface of the inner tube 41, and the baffles 44 are in contact with the inner arc surface of the outer tube 42. By driving the baffle 44 to rotate horizontally and move up and down simultaneously with the inner tube 41, the feces are evenly stirred. During the stirring process, since the baffle 44 is an inclined plate, there is a gap on the lower side of the baffle 44. Fresh air between the outer arc surface of the outer tube 42 and the inner arc surface of the fecal fermentation tank 1 will enter the inner tube 41 through the gap and finally be discharged from the upper end of the inner tube 41, guiding the air flow trajectory, enabling the feces to come into contact with fresh air more comprehensively and improving the ventilation quality of fecal fermentation. The diversion and ventilation mechanism 4 further includes a non-woven fabric 43, and the non-woven fabric 43 is respectively arranged on the inner arc surface of the inner tube 41 and the outer arc surface of the outer tube 42 to prevent feces from passing through the air holes on the surfaces of the inner tube 41 and the outer tube 42. The diversion and ventilation mechanism 4 further includes collar 48 and spring 49. Collars 48 are respectively arranged at the upper and lower ends of the outer arc surface of the inner tube 41, and the collars 48 are installed in cooperation with the fecal fermentation tank 1. The outer arc surface of the lower collar 48 is in contact with the inner wall of the fecal fermentation tank 1, and the outer arc surface of the upper collar 48 is in contact with the inner arc surface of the air outlet pipe 3. Springs 49 are provided between the collars 48 and the fecal fermentation tank 1, and the springs 49 are respectively sleeved on the outer arc surface of the inner tube 41. By the contact between the collar 48 and the inner wall of the fecal fermentation tank 1, the upper and lower ends of the inner tube 41 are sealed, and by using the elastic force of the spring 49, the up and down movement of the inner tube 41 is made more stable. The diversion and ventilation mechanism 4 further includes a mounting plate 46 and an electric push rod 47. The electric push rod 47 is arranged at the lower end of the fecal fermentation tank 1, and the lower end of the telescopic end of the electric push rod 47 is provided with a mounting plate 46. The mounting plate 46 is rotatably connected to the inner tube 41 through a bearing. The input end of the electric push rod 47 is electrically connected to the output end of the PLC controller 5 to provide power for the up and down movement of the inner tube 41. The diversion and ventilation mechanism 4 further includes a motor 45. The motor 45 is arranged on the lower surface of the mounting plate 46, and the output shaft of the motor 45 is fixedly connected to the lower end of the inner tube 41. The input end of the motor 45 is electrically connected to the output end of the PLC controller 5 to provide power for the rotation of the inner tube 41.

[0024] The working principle of a manure fermentation device provided by the present utility model is as follows: During use, the processed livestock manure is poured into the interior of the manure fermentation tank 1, and the livestock manure ferments inside the manure fermentation tank 1. During the fermentation process, external air is conveyed from the air inlet pipe 2 to the interior of the manure fermentation tank 1 by an external blower. The fresh air is located between the outer arc surface of the outer pipe 42 and the inner arc surface of the manure fermentation tank 1. Affected by the accumulation of manure, the speed at which the fresh air penetrates the manure and enters the inner pipe 41 is relatively slow. As the external air continuously enters, the air pressure inside the manure fermentation tank 1 gradually increases. Then, the motor 45 is started through the PLC controller 5. The output shaft of the motor 45 drives the inner pipe 41 and the baffle 44 to rotate, and the inclined baffle 44 is used to stir the manure. During the stirring process, voids appear in the space below the baffle 44, and the external high-pressure air quickly enters the interior of the inner pipe 41 through the voids and finally discharges from the upper end of the inner pipe 41, guiding the flow trajectory of the air. During this process, the fresh air contacts the manure, providing oxygen for the fermentation of the manure. At the same time, the electric push rod 47 is started. The telescopic end of the electric push rod 47 drives the mounting plate 46 to move up and down, overcoming the elastic force of the spring 49, so that the inner pipe 41 drives the baffle 44 to move up and down during rotation, comprehensively stirring the manure, making the fresh air contact the manure more evenly, and improving the fermentation quality of the manure.

[0025] It should be noted that, in the above embodiments, the PLC controller 5 disclosed can be an NX7 model PLC controller, and the electric push rod 47 and the motor 45 can be freely configured according to the actual application scenario. The electric push rod 47 can be an LAM1 model electric push rod, and the motor 45 can be a 42BYHJ01 model stepping reduction motor. The PLC controller 5 controls the electric push rod 47 and the motor 45 to work using common methods in the prior art.
