[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model proposes: a biofertilizer gas supplement stirring device, a stirring tank 1, a tank cover 2, a hollow shaft tube 3 and a stirring blade 4, the hollow shaft tube 3 is arranged on the tank cover 2 arranged on the upper port of the stirring tank 1, and the hollow shaft tube 3 is stably installed on the stirring tank 1 by using the tank cover 2 to ensure that the three are stably used together, and the hollow support rod 306 on the hollow shaft tube 3 is used to rotate and stir the biofertilizer raw materials in the stirring tank 1 with the stirring blade 4, and at the same time, the gas to be supplemented is discharged from the gas outlet 3061 on the hollow support rod 306 The gas is discharged and injected into the stirred biofertilizer raw material, and the gas replenishment operation is completed during the stirring process. The hollow shaft tube 3 is connected to the connecting pipe 501 on the air pump 5 through the adapter 305 arranged at the upper end, so that the air pump 5 and the hollow shaft tube 3 are stably connected together by using the adapter 305 and the connecting pipe 501. The air pump 5 is connected to the gas storage device that needs to be replenished with gas, so that the gas is smoothly injected into the gas flow channel inside the hollow shaft tube 3, and the gas is smoothly injected into the stirring tank 1. The hollow shaft tube 3 is fixedly connected to the tube body in the internal cavity of the stirring tank 1. There is a hollow support rod 306, and the hollow support rod 306 is provided with gas outlet nozzles 3061 distributed at equal intervals. The gas entering the hollow shaft tube 3 is evenly dispersed into the stirring tank 1 by the cooperation of the two. During the gas replenishment process, the gas is evenly injected into the stirred bio-fertilizer raw material, which is convenient for the gas and the bio-fertilizer raw material to be quickly mixed together, thereby improving the gas replenishment efficiency. The base plate 401 on the stirring blade 4 is fixedly connected to the hollow support rod 306 through a connecting clamp 405. The base plate 401 is rotatably connected to the movable plate 402, and the movable plate 402 and the base plate 401 An elastic spring plate 404 is arranged in between, so as to facilitate the stable installation of the stirring blade 4 on the hollow support rod 306. During operation, the stirring blade 4 rotates in the stirring tank 1 along with the hollow support rod 306 to stir the biofertilizer raw material. At the same time, when the stirring blade 4 encounters a large resistance during the stirring process, the movable plate 402 can rotate on the base plate 401 to reduce the area of ​​the entire stirring blade 4 facing the biofertilizer raw material, reduce the resistance, ensure that the stirring blade 4 can be driven smoothly, and effectively stir the biofertilizer raw material. After the resistance becomes smaller, it is reset under the action of the elastic spring plate 404.

[0022] like Figure 1 and Figure 2 As shown, in some embodiments, the second sprocket 303 fixedly connected to the hollow shaft tube 3 is transmission-connected to the first sprocket 302 on the output shaft of the driving motor 301 through the transmission chain 304, and the driving motor 301 is fixedly connected to the tank cover 2, so that the driving motor 301 can be stably installed, so that during operation, the second sprocket 303 and the hollow shaft tube 3 can be smoothly rotated on the tank cover 2 through the cooperation of the first sprocket 302 and the transmission chain 304, and the hollow shaft tube 3 is rotationally connected to the tank cover 2 through the bearing seat 307, so as to ensure that the hollow shaft tube 3 can be smoothly rotated on the tank cover 2;

[0023] The cavity inside the hollow shaft tube 3 is connected to the internal cavity of the hollow support rod 306, and the air outlet nozzles 3061 distributed at equal intervals on the hollow support rod 306 are connected to the internal cavity, so as to form a through gas flow channel between the hollow shaft tube 3, the hollow support rod 306 and the air outlet nozzles 3061, so that the gas is smoothly input into the biofertilizer raw material, and is smoothly mixed with the biofertilizer raw material with stirring, so as to achieve the purpose of stirring and replenishing gas. A one-way air outlet valve is arranged in the air outlet nozzle 3061, so as to smoothly inject the gas into the biofertilizer raw material. The door prevents the biofertilizer raw materials from entering the air outlet nozzle 3061 during the stirring process, ensuring that the air outlet nozzle 3061 is in a smooth state and the gas is smoothly transported. The adapter 305 is rotatably connected to the upper end of the hollow shaft tube 3. A sealing ring is arranged at the connection portion between the upper end of the hollow shaft tube 3 and the adapter 305, so as to facilitate the stable connection between the two. At the same time, when the hollow shaft tube 3 rotates, no motion interference is generated, ensuring that the hollow shaft tube 3 can be smoothly driven by the driving motor 301, and the stirring blade 4 rotates in the stirring tank 1 to stir the biofertilizer raw materials.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the connecting seat 4021 integrally provided on the movable plate 402 is rotatably connected to the connecting groove 4011 opened at the corresponding position on the base plate 401 through the connecting shaft 403, and the movable plate 402 is stably installed on the base plate 401 by using the connecting shaft 403, and it is ensured that when the stirring blade 4 rotates together with the hollow support rod 306 on the hollow shaft tube 3 inside the stirring tank 1 to stir the biofertilizer raw material, when the resistance of the biofertilizer raw material is large, the movable plate 402 can rotate on the base plate 401, reducing the area of ​​the entire stirring blade 4 facing the biofertilizer raw material, reducing the resistance, so that the stirring blade 4 can smoothly rotate to stir the biofertilizer raw material, ensuring stable stirring, and the middle position of the elastic spring plate 404 is fixedly connected to the base plate 4 01, and both ends are respectively connected to the movable plate 402 at the corresponding positions, so as to stably install the elastic spring plate 404 on the base plate 401 and the movable plate 402. The elastic spring plate 404 will produce a deformation adapted to the movable plate 402 on the base plate 401. At the same time, after the resistance of the movable plate 402 becomes smaller, the elastic spring plate 404 pushes the movable plate 402 to rotate and reset on the base plate 401, and a fastening bolt 406 is arranged on the connecting ear integrally arranged at the end of the connecting clamp 405, so that after the connecting clamp 405 is put on the hollow support rod 306, the connecting clamp 405 is tightly fixed on the hollow support rod 306 by the fastening bolt 406, so as to improve the stability of the installation of the entire stirring blade 4 and ensure smooth stirring of the bio-fertilizer raw materials.

[0025] like Figure 1 As shown, in some embodiments, an exhaust pipe 201 is arranged at the exhaust hole position opened on the tank cover 2, and a pressure relief valve is arranged on the exhaust pipe 201. When the waste gas generated in the process of bio-fertilizer production inside the mixing tank 1 accumulates and reaches the pressure value set by the pressure relief valve, the waste gas enters the exhaust pipe 201 from the exhaust hole. At this time, the pressure relief valve opens under the action of air pressure, and the waste gas is smoothly discharged from the mixing tank 1. The exhaust pipe 201 is connected to the external waste gas treatment equipment to directly treat the generated waste gas to avoid waste gas pollution of the environment. A sealing gasket is arranged between the tank cover 2 and the mixing tank 1 to facilitate the stable connection between the two and seal the mixing tank 1, so as to stir, ferment and other processes of the bio-fertilizer raw materials.
