[0002] Microbial fertilizer is a product that uses the life activities of microorganisms to give crops a specific fertilizer effect. It is also called inoculant or bacterial fertilizer. It does not contain nutrients itself and cannot replace chemical fertilizers. In a broad sense, biological fertilizer is a product that contains both the nutrients needed by crops and microorganisms. It is a combination of biological, organic and inorganic. It can replace chemical fertilizers and provide various nutrients required for the growth and development of crops. Functional microbial fertilizers require the use of a mixing granulation device for processing and granulation.

DETAILED DESCRIPTION
[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.
[0032] Embodiment 1:
[0033] like Figure 1—4 shows: a composite microbial fertilizer extrusion device, comprising a collecting tank 1, a screw feeder 2 is installed above the collecting tank 1, a feeding tank 3 is arranged at one end of the screw feeder 2, the other end of the screw feeder 2 is inserted into the inner side of a cooling tank 5, a cutting assembly 4 is installed in the cooling tank 5, an extrusion slot 21 is provided on the end of the screw feeder 2 facing the cutting assembly 4, an exhaust fan 6 is installed on the top of the cooling tank 5, the bottom end of the cooling tank 5 is connected to one end of the collecting tank 1, a material discharge cover plate 12 is installed at the bottom of the collecting tank 1, an air inlet 7 is provided on the bottom side of the cooling tank 5, a cooling assembly 8 is installed on the cooling tank 5 outside the air inlet 7, and the cooling assembly 8 includes a side plate 81, the side plate 81 are arranged on both sides of the heat-conducting fin 82, and the heat-conducting fin 82 is inserted with a cooling pipe 83. When the fertilizer cut into granules by the cutting component 4 falls in the cooling trough 5, the air cooled by the cooling component 8 and entering the cooling trough 5 flows upward rapidly, so that the material is quickly hardened and cooled under the action of water cooling and air cooling, and deformation or mutual adhesion of the material is effectively avoided. A buffer plate 11 is installed on the inner bottom surface of the collecting trough 1 vertically below the cooling trough 5, and the edge of the vertical projection of the cooling trough 5 on the horizontal plane does not exceed the edge of the vertical projection of the buffer plate 11 on the horizontal plane. When the hardened material falls on the surface of the buffer plate 11, the buffer plate 11 produces elastic deformation, thereby buffering and absorbing the impact potential energy of the falling material, and avoiding deformation or mutual adhesion of the material. Crushing, the buffer plate 11 is a fluororubber plate structure with a thickness of not less than 5mm. The buffer plate 11 is resistant to high temperature, has good chemical stability, and is not easy to adhere to materials on the surface, thereby ensuring that the fertilizer can smoothly roll off the surface of the buffer plate 11. The bottom surface of the collecting tank 1 is inclined downward at one end away from the cooling tank 5, and the unloading cover plate 12 is installed at the bottom end of the collecting tank 1. The material slides along the inclined bottom surface of the collecting tank 1 to the top of the unloading cover plate 12, which is convenient for personnel to collect fertilizers after opening the unloading cover plate 12. The side plate 81 is arranged on the left and right sides of the air inlet 7, and the two ends of the cooling pipe 83 are respectively connected to the inlet and return water ends of the refrigeration unit. The cooling medium flowing in the cooling pipe 83 reduces the surface temperature of the cooling pipe 83, thereby reducing the heat transfer fins 8 2, so that the temperature of the air flowing through the surface of the heat-conducting fins 82 is quickly reduced, thereby reducing the intake air temperature by combining water cooling with air cooling. The end of the screw feeder 2 plugged into the cooling groove 5 is tilted upward, and the screw feeder 2 can transport the material to a higher place, thereby extending the passing time of the material in the cooling groove 5, thereby effectively extending the cooling time of the material. The cutting assembly 4 includes a motor 41 and a rotating tool holder 42, and the motor 41 is installed on the cooling groove 5. The rotating tool holder 42 is abutted against an end face of the screw feeder 2 where the extrusion groove 21 is opened, and the rotating tool holder 42 is installed on the output shaft of the motor 41. The motor 41 can drive the rotating tool holder 42 to rotate at a high speed, thereby quickly cutting the extruded material in the extrusion groove 21.
[0034] The working principle of the present technical solution is as follows: the softened material is conveyed to the direction of the cutting assembly 4 by the screw feeder 2, and extruded through the extrusion slot 21. At this time, the motor 41 drives the rotating knife holder 42 to rotate at a high speed to cut the extruded material into granules. The granular material falls under the action of gravity. In the process of passing through the cooling slot 5, the running exhaust fan 6 allows the outside air to enter the cooling slot 5 through the air inlet 7, and flow from the bottom of the cooling slot 5 to the top of the cooling slot 5 at a high speed. Before entering the air inlet 7, the air first flows through the surface of the heat conducting fins 82. At this time, the cooling medium flowing in the cooling pipe 83 reduces the The surface temperature of the cooling tube 83, and then the temperature of the heat-conducting fins 82 is reduced by heat transfer, so that the temperature of the air flowing through the surface of the heat-conducting fins 82 is quickly reduced, thereby reducing the intake temperature by water cooling and air cooling, so that the granular material can be quickly cooled and hardened during the falling process in the cooling trough 5; when the hardened material falls on the surface of the buffer plate 11, the buffer plate 11 produces elastic deformation, thereby buffering and absorbing the impact potential energy of the falling material to avoid deformation or breakage of the material; the material slides along the inclined bottom surface of the collecting trough 1 to the top of the lower material cover 12, making it convenient for personnel to collect fertilizers.
