[0024] According to this specific embodiment, the tank body 101 is used to accommodate livestock and poultry manure, biogas slurry and straw powder for fermentation.

[0025] Among them, the feed port 103 is fixedly connected and communicated with the tank body 101, and is located at the top of the tank body 101; the discharge port 104 is fixedly connected and communicated with the tank body 101, and is located at the side of the tank body 101; the first rotating shaft 105 is rotatably connected to the tank body 101, and is located at the side of the tank body 101; the first base 106 is fixedly connected to the first rotating shaft 105, and is located at the bottom of the first rotating shaft 105; the connecting shaft 107 is rotatably connected to the tank body 101, and is located at the side of the tank body 101; the output rod of the hydraulic cylinder 108 is fixedly connected to the connecting shaft 107, and is located at the side of the connecting shaft 107; the second rotating shaft 109 is fixedly connected to the hydraulic cylinder 108, and is located at the side of the hydraulic cylinder 108; the second base 110 is rotatably connected to the second rotating shaft 109, and is located at the side of the second rotating shaft 109. During use, the first base 106 and the second base 110 are fixed to the ground, and materials such as livestock and poultry manure, biogas slurry, and straw powder are fed into the tank body 101 through the feed port 103, and the materials are fermented in the tank body 101; when the materials in the tank body 101 need to be discharged, the output rod of the hydraulic cylinder 108 is controlled to extend to push the connecting shaft 107, and the connecting shaft 107 rotates and pushes the tank body 101, causing the tank body 101 to rotate counterclockwise along the first rotating shaft 105, causing the discharge port 104 to tilt downward. At this time, the materials in the tank body 101 will flow to the discharge port 104 under the action of gravity, allowing smooth discharge. When the tank body 101 rotates, the hydraulic cylinder 108 will rotate along the second rotating shaft 109 to avoid interfering with the rotation of the tank body 101.

[0026] Secondly, the motor 111 is fixedly connected to the tank body 101 and is located on the side of the tank body 101. The hollow rod 112 is rotatably connected to the tank body 101 and is fixedly connected to the output end of the motor 111 and is located on the side of the tank body 101.

When the material in the tank body 101 needs to be discharged, the output rod of the hydraulic cylinder 108 is controlled to extend to push the connecting shaft 107, and the connecting shaft 107 rotates and pushes the tank body 101, so that the tank body 101 rotates counterclockwise along the first rotating shaft 105, so that the discharge port 104 tilts downward. At this time, the material in the tank body 101 will flow to the discharge port 104 under the action of gravity, so that it can be discharged smoothly.
