[0024] A pig feed fermentation device includes a housing 1. A top cover 8 is rotatably arranged at the top of the housing 1. The housing 1 is a cylindrical structure with an upward opening, and its bottom wall is arranged as a conical structure. A support column 24 is fixedly arranged on the bottom wall of the housing 1. The top of the housing 1 is rotatably connected to the top cover 8 through a hinge, and the opening and closing part is detachably connected through a plurality of snap fasteners 14. The snap fasteners 14 are common snap fastening structures in the prior art, and can conveniently fasten the top cover 8 and the housing 1 together or open them conveniently.

[0025] During use, first mix appropriate raw materials in a certain proportion, then open the top cover 8, pour the proportioned raw materials, fermenting agent and appropriate amount of water into the interior of the housing 1, and then fasten the top cover 8 so that the top cover 8 and the housing 1 are fastened together, and then carry out fermentation. Generally, fermentation takes 1-2 days. Since a sealing ring 29 adapted to the inner wall of the housing 1 is arranged on the bottom wall of the top cover 8, the sealing ring 29 can enhance the airtightness of the housing 1 and ensure the airtight space for fermentation.

[0026] A heat preservation cavity 2 is arranged on the outer wall of the housing 1. A water inlet pipe 15 is communicated with the top of the heat preservation cavity 2. A plurality of electric heating rods 3 are arranged inside the heat preservation cavity 2. The plurality of electric heating rods 3 are evenly distributed inside the heat preservation cavity 2. A universal nozzle 9 penetrates through the top cover 8. The universal nozzle 9 is communicated with the heat preservation cavity 2 through a water delivery pipe 11. The bottom end of the water delivery pipe 11 penetrates through the side wall at the bottom end of the heat preservation cavity 2 and is communicated. The middle section of the water delivery pipe 11 is arranged as an elastic hose 17. A water pump 18 is arranged at the top end of the water delivery pipe 11 and is communicated with the universal nozzle 9.

[0027] A control panel 16 is also provided on the upper cover 8. The dual-probe temperature sensor 4 is arranged on the side wall of the housing 1, and the two sensing probes are respectively arranged inside the housing 1 and inside the heat preservation cavity 2. The raw materials ferment inside the housing 1, and the fermentation temperature is generally preferably 25-30 °C. At the beginning of fermentation, the temperature is relatively low, and the heat generated during the fermentation process will affect the fermentation temperature. Therefore, it is necessary to cooperate with the heat preservation cavity 2, the dual-probe temperature sensor 4 and the control panel 16 to control the temperature.

[0028] According to the temperatures inside the housing 1 and the heat preservation cavity 2 sensed by the dual-probe temperature sensor 4, the sensed information can be transmitted to the control system inside the control panel 16. According to the preset optimal temperature, the electric heating rod 3 can be started to heat, or cold water can be added to the heat preservation cavity 2 to reduce the temperature, and the temperature can be maintained at the optimal temperature.

[0029] A spiral stirring roller 5 is rotatably arranged inside the housing 1. The spiral stirring roller 5 includes a spiral stirring paddle 6 and a scraper 7. The spiral stirring roller 5 also includes a rotating shaft 19. The bottom end of the rotating shaft 19 penetrates through the baffle 21 and is fixedly connected to the output shaft of the motor 23.

When the rotating shaft 19 rotates, the scraper 7 can be driven to rotate at the same time to scrape off the raw materials adhering to the side wall of the housing 1.

[0031] An air outlet pipe 10 penetrates through the upper cover 8. An air filtration box 12 is arranged at the top end of the air outlet pipe 10. A gas valve 27 is arranged inside the air outlet pipe 10. An activated carbon adsorption layer 28 is arranged inside the air filtration box 12, and the top wall of the air filtration box 12 is set as a ventilation mesh plate.

[0032] When the gas valve 27 is opened, the heat generated during fermentation is discharged from the air outlet pipe 10 to the air filtration box 12 together with the gas. After the activated carbon adsorption layer 28 adsorbs the odor, it is discharged into the air through the ventilation mesh plate.

[0034] After fermentation is completed, the electric telescopic rod 13 is started. When it drives the mounting frame 22 to move down to the cross plate 30, at this time, the baffle 21 also moves down to below the port of the discharge pipe 31, just exposing the port of the discharge pipe 31. The fermented feed is discharged from the discharge pipe 31 to the outside for unified storage, and then the baffle 21 is moved up back into the through groove 20 to block the through groove.

[0035] The water pump 18 is started, and the warm water inside the heat preservation cavity 2 is conveyed to the universal nozzle 9 through the water delivery pipe 11. The universal nozzle 9 is used to spray and wash the inside of the housing 1, which has a good cleaning effect and can also realize the reuse of wastewater.
