[0043] The discharging unit 103 includes a discharging cylinder 1031, a spiral feeding shaft 1032 and a discharging motor 1033.

[0044] The discharging cylinder 1031 is fixed to the bottom of the mixing tank 101 and is in communication with the inner cavity of the mixing tank 101, the discharging motor 1033 is fixed to one end of the discharging cylinder 1031, and the output end of the discharging motor 1033 penetrates into the interior of the discharging cylinder 1031 and is fixedly connected with the spiral feeding shaft 1032.

[0045] A plurality of feeding ports 102 are uniformly arranged in the circumferential direction, and the number of the discharge ports 304 matches the number of the feeding ports 102.

[0046] In this embodiment, it needs to be supplemented that: a plurality of feeding ports 102 are communicated with each raw material bin (such as livestock and poultry manure, crop straw, fermentation catalyst and other raw materials) through pipelines, the bin is located at a high place of the mixing assembly 1, and the raw materials can slide down by gravity, in addition, a plurality of transmission gears 302 are rotationally connected with the top of the inner wall of the mixing tank 101 and the bottom of each partition plate 104, respectively.

[0047] When mixing, the operation principle is as follows:

[0049] The inner tooth ring plate 303 at the top rotates, and when the discharge port 304 is aligned with the feeding port 102, the raw material falls into the first mixing bin through the feeding port 102 and the discharge port 304, and when the discharge port 304 is completely misaligned with the feeding port 102, the discharge is stopped, thereby realizing intermittent discharge operation.

[0050] In this process, the high-speed rotating stirring rod 203 disperses and mixes the raw material entering the first mixing bin, and at the same time, the inner tooth ring plate 303 below the partition plate 104 rotates synchronously at a low speed, and when the discharge slot 305 on the inner tooth ring plate 303 below the first partition plate 104 is aligned with the fan-shaped discharge port 105 on the first partition plate 104, the raw material in the first mixing bin falls into the second mixing bin, and when the discharge slot 305 on the inner tooth ring plate 303 below the second partition plate 104 is aligned with the fan-shaped discharge port 105 on the second partition plate 104, the raw material falls into the third mixing bin, and finally the raw material falls into the bottom of the mixing tank 101.

[0051] The raw material is stored in each mixing bin for a period of time and is dispersed and stirred by the stirring rod 203. Through this structure, the raw material in each mixing bin will not fill the mixing bin, and the raw material can be better dispersed and mixed, so that the mixing efficiency is higher and the mixing is more uniform.

[0052] The raw material at the bottom of the mixing tank 101 is fully stirred, and at this time the unloading motor 1033 can be started, the unloading motor 1033 drives the rotating screw feeding shaft 1032, the raw material at the bottom of the mixing tank 101 enters the unloading cylinder 1031 and is driven out by the rotating screw feeding shaft 1032, realizing unloading operation.

[0053] Please refer to Figs. 2-4 , the fan-shaped discharge ports 105 on the adjacent two partition plates 104 are distributed in a misaligned manner in the circumferential direction, and the discharge slots 305 on the inner tooth ring plate 303 are aligned in the vertical direction.

[0054] In this embodiment: through this structure, when one mixing bin is discharging, the two adjacent mixing bins are in a non-discharging state, thereby enabling the raw material to stay in each mixing bin for a period of time, thereby achieving better stirring and mixing.

[0055] Please refer to Figs. 2-4 , the stirring rod 203 at the bottom of each mixing bin is attached to the upper surface of the partition plate 104, and the stirring rod 203 distributed at the bottom of the rotating shaft 202 is attached to the inner wall bottom of the mixing tank 101.

[0056] In the embodiment, the material on the partition plate 104 and the bottom of the inner wall of the mixing tank 101 can be scraped by rotating the stirring rod 203 attached to the partition plate 104 and the bottom of the inner wall of the mixing tank 101, so that the raw materials in each stirring bin can be completely pushed and discharged, and the raw materials at the bottom of the mixing tank 101 can be pushed into the discharge pipe 1031.
