[0002] Fertilizer fermentation refers to the process of converting organic matter into fertilizer through the action of microorganisms. This process can improve the fertilizer efficiency, reduce pathogens and parasite eggs, and also help improve soil structure and increase soil organic matter content. During fertilizer fermentation, elements such as nitrogen, phosphorus, and potassium need to be added to supplement the elements required by plants. After the fertilizer fermentation is completed, it needs to be granulated.

[0020] like Figure 1-4As shown, a biological extruded granular nitrogen fertilizer fermentation device includes a fermentation tank 1 and an aeration component 2. The aeration component 2 is rotatably connected inside the fermentation tank 1 and has a hollow structure. The surface of the aeration component 2 is provided with evenly distributed air outlet holes 28. The top of the fermentation tank 1 is provided with an air intake component 4 for aeration into the aeration component 2. The top of the air intake component 4 is fixedly connected with a positive and negative motor 3. The output shaft of the positive and negative motor 3 is fixedly connected to the top of the aeration component 2. The fermentation tank 1 includes a tank body 11 and support legs 12. The bottom end of the tank body 11 is fixedly connected with equidistantly distributed support legs 12. The middle part of the bottom end of the tank body 11 is fixedly connected with a discharge pipe 13. The bottom end of the discharge pipe 13 is provided with a valve 14. The top of the side wall of the tank body 11 is fixedly connected with a feed hopper 15.

[0021] According to the above structure, when in use, the organic fertilizer mixed with nitrogen raw materials is put into the tank 11 through the feed hopper 15. The fertilizer ferments inside the tank 11. When the fermentation enters the aeration stage, air is introduced into the aeration component 2 through the air intake component 4. Then, the aeration component 2 is rotated by the forward and reverse motor 3. Air is evenly sprayed into the fertilizer through the air outlet 28 on the surface of the aeration component 2, thereby better aerating the fertilizer.

[0022] like Figure 3 and 4 As shown, the ventilation component 2 includes a main pipe 21 and a screw rod 22. The bottom end of the main pipe 21 is fixedly connected to the screw rod 22, and the top end of the screw rod 22 is fixedly connected to a first ring body 23. The bottom of the main pipe 21 is connected to the first ring body 23. A second ring body 24 is arranged around the periphery of the first ring body 23. A connecting pipe 25 is arranged between the first ring body 23 and the second ring body 24, which are equidistantly distributed around the axis of the first ring body 23. The first ring body 23 and the second ring body 24 are connected through the connecting pipe 25. The bottom of the screw rod 22 is rotatably connected to the inside of the discharge pipe 13.

[0023] According to the above structure, during use, the positive and negative motor 3 drives the main pipe 21 to rotate, which in turn drives the screw rod 22 to rotate, thereby agitating the fertilizer. The main pipe 21 drives the first ring body 23, the second ring body 24, the connecting pipe 25 and the stirring pipe 26 to rotate, thereby agitating the fermenting fertilizer and improving air permeability.

[0024] like Figure 3 and 4As shown, the bottom of the second ring 24 and the bottom of the connecting pipe 25 are both fixedly connected to equidistantly distributed stirring pipes 26. The air outlets 28 are evenly distributed on the side wall of the stirring pipes 26. The air intake assembly 4 includes a cylinder 41 fixedly connected to the middle of the top of the fermenter 1. The top of the main pipe 21 is rotatably connected to the inside of the cylinder 41 through a sealed bearing. The side wall of the cylinder 41 is fixedly connected to an air intake pipe 42. The top of the main pipe 21 is provided with equidistantly distributed air intake slots 27. The top of the cylinder 41 is fixedly connected to a forward and reverse motor 3. The output shaft of the forward and reverse motor 3 is fixedly connected to the top of the main pipe 21.

[0025] According to the above structure, when aeration is performed, the air inlet pipe 42 is connected to the external air pump, and the air pump vents into the interior of the main pipe 21. The gas enters the interior of the main pipe 21 through the air inlet groove 27, then enters the interior of the connecting pipe 25 and the second ring 24 through the first ring body 23, and finally is sprayed into the fertilizer inside the main pipe 21 through the air outlet 28 on the side wall of the stirring pipe 26. When fermentation is completed, the forward and reverse motor 3 drives the screw rod 22 to rotate in the opposite direction and discharges the fertilizer through the discharge pipe 13.

[0026] The working principle of this utility model is as follows: During use, organic fertilizer mixed with nitrogen-containing raw materials is placed into the tank 11 through the feed hopper 15. The fertilizer ferments inside the tank 11. When fermentation enters the aeration and oxygenation stage, air is introduced into the aeration component 2 through the air intake component 4. Then, the forward and reverse motor 3 drives the aeration component 2 to rotate, and air is evenly sprayed into the fertilizer through the air outlet 28 on the surface of the aeration component 2, thus better aerating the fertilizer. During use, the forward and reverse motor 3 drives the main pipe 21 to rotate, which in turn drives the screw rod 22 to rotate, thus agitating the fertilizer. The main pipe 21 drives... The first ring 23, the second ring 24, the connecting pipe 25, and the stirring pipe 26 rotate to stir the fermenting fertilizer and improve air permeability. When aeration is performed, the air inlet pipe 42 is connected to an external air pump, which vents air into the main pipe 21. The gas enters the main pipe 21 through the air inlet slot 27, then enters the connecting pipe 25 and the second ring 24 through the first ring 23, and finally is sprayed into the fertilizer inside the main pipe 21 through the air outlet 28 on the side wall of the stirring pipe 26. After fermentation is completed, the forward and reverse motor 3 drives the screw rod 22 to rotate in the opposite direction, discharging the fertilizer through the discharge pipe 13.
