The two driving motors are not shown in the figure. After starting the two driving motors, the rotating shafts of the two driving motors respectively drive the two driving rollers 31 to rotate, and the two driving rollers 31 rotate in opposite directions. When the two feeding belts 3 are running, the two driven rollers 32 can be driven to rotate; when the compound fertilizer particles first fall onto the feeding belt 3 located above, when the compound fertilizer particles are transported to the edge of the feeding belt 3, the compound fertilizer particles fall downward onto the feeding belt 3 located below, so as to change the position of the compound fertilizer particles, and then the compound fertilizer particles are transported by the feeding belt 3 located below, and finally fall into the collection frame 7.

[0018] like Figure 2 , Figure 3 and Figure 4As shown, two water tanks 5 are fixed on one side of the box body 1 away from the fixed shell 4, and the water tanks 5 are connected with a connecting pipe 51 that penetrates the box body 1. The connecting pipes 51 on the two water tanks 5 are respectively located on the inner sides of the two feeding belts 3, and the exhaust pipe 41 is located on the inner side of the connecting pipe 51. The exhaust nozzle 42 penetrates the connecting pipe 51 and is fixedly connected to the connecting pipe 51, and a filter 43 is fixed on the exhaust end of the exhaust nozzle 42. After water is pumped into the two water tanks 5 by an external water pump, the water enters the connecting pipe 51, which plays a role in water cooling the exhaust pipe 41, so as to avoid the situation that the temperature of the exhaust pipe 41 rises after the temperature in the box body 1 rises due to the temperature of the compound fertilizer particles themselves, resulting in a decrease in the wind cooling effect; after the wind in the exhaust pipe 41 is discharged through water cooling, the effect of cooling the compound fertilizer particles can be further improved; the filter 43 can prevent some smaller impurities from entering the exhaust nozzle 42.

[0019] like Figure 2 , Figure 3 and Figure 4 As shown, there are two groups of exhaust pipes 41 on the fixed shell 4, and the two groups of exhaust pipes 41 are distributed up and down, and the exhaust nozzles 42 on the two groups of exhaust pipes 41 are respectively located on the opposite sides of the two groups of exhaust pipes 41; there are also two groups of connecting pipes 51 on the water tank 5. The two groups of exhaust pipes 41 on the fixed shell 4 are arranged so that the upper group of exhaust pipes 41 can cool the part of the feeding belt 3 located on the top surface, and cool the compound fertilizer particles located on the top surface of the feeding belt 3; while the lower group of exhaust pipes 41 can cool the part of the feeding belt 3 located on the bottom surface, so as to eliminate the influence of the temperature of the compound fertilizer particles themselves on the feeding belt 3 and avoid the temperature rise of the feeding belt 3.

[0020] like Figure 2 As shown, a connecting frame 71 is slidably connected inside the collecting frame 7, a perforated plate 72 is fixed on the inner side of the connecting frame 71, and the diameter of the perforations on the perforated plate 72 is larger than the particle size of the compound fertilizer particles; a fixedly connected electric telescopic rod 73 is passed through one side of the collecting frame 7, the telescopic end of the electric telescopic rod 73 is fixed to the connecting frame 71, and a limiting rod 74 that passes through the collecting frame 7 and is slidably connected to the collecting frame 7 is fixed on the side of the connecting frame 71 away from the electric telescopic rod 73; a connecting shell 76 is fixed on the box body 1, an air supply pipe is connected to the connecting shell 76, and an air outlet pipe 75 that passes through the box body 1 and the collecting frame 7 in sequence is connected to the connecting shell 76, and the air outlet pipe 75 is located below the connecting frame 71, and exhaust holes are opened on the air outlet pipe 75. There are three groups of air outlet pipes 75, and the three groups of air outlet pipes 75 are staggered up and down (such as Figure 2When the compound fertilizer particles enter the collecting frame 7, they are blocked by the perforated plate 72, and then the compound fertilizer particles fall downward evenly through the perforations on the perforated plate 72; when the external fan discharges the wind into the connecting shell 76 through the air supply pipe, the wind is discharged through the exhaust holes on the three groups of air outlet pipes 75. At the same time, the arrangement of the three groups of air outlet pipes 75 can disperse the compound fertilizer particles falling downward, so as to thoroughly and effectively cool the compound fertilizer particles.

[0021] like Figure 2 As shown, two scrapers 10 are fixed in the box 1, and the tops of the two scrapers 10 are in contact with the bottom surfaces of the two feeding belts 3 respectively; an inclined plate 6 located below the two feeding belts 3 is fixed on one side of the box 1, and the inclined plate 6 is located above the collecting frame 7. The scrapers 10 can scrape off the compound fertilizer particles attached to the feeding belts 3; the inclined plate 6 can accurately discharge the compound fertilizer particles that fall from the feeding belts 3 located below onto the perforated plate 72.

[0022] like Figure 1 and Figure 2 As shown, a screw rod 8 connected by a thread passes through the top of the box body 1, and one end of the screw rod 8 located in the box body 1 is rotatably connected to a lifting plate 81, and the lifting plate 81 is slidably connected to the inner wall of the box body 1 and is located above the two feeding belts 3; the top of the box body 1 is also connected to an exhaust port 9. The height of the lifting plate 81 can be adjusted by rotating the screw rod 8, so as to facilitate the spiral feeding piece 2 to be discharged to the compound fertilizer particles on the feeding belt 3 located above to be leveled; the exhaust port 9 can exhaust the air in the box body 1.

[0023] like Figure 1 and Figure 2 As shown, the two sides of the box body 1 are respectively connected with a water injection pipe 11 and a drainage pipe 12. Water can be injected into the box body 1 through the water injection pipe 11, so that the water level is located below the top of the collection frame 7, so as to play a role in cooling the inside of the box body 1, and the compound fertilizer particles entering the collection frame 7 can be cooled to a certain extent, and the drainage pipe 12 can discharge the water, so that the water in the box body 1 circulates, and further plays a role in cooling the inside of the box body 1.

[0024] When in use, the spiral feeding piece 2 is an existing auger structure, which will not be elaborated here. When the compound fertilizer particles enter the box body 1 through the spiral feeding piece 2 and fall on the feeding belt 3 located above, when the feeding belt 3 transports the compound fertilizer particles, the external fan blows air into the fixed shell 4 through the air inlet pipe, and the exhaust nozzle 42 on the exhaust pipe 41 discharges the air to cool the compound fertilizer particles; when the compound fertilizer particles are transported to the edge of the feeding belt 3 located above, the compound fertilizer particles fall downward to the feeding belt 3 located below, changing the position of the compound fertilizer particles. After the subsequent compound fertilizer particles are cooled by air again, all the compound fertilizer particles can be fully cooled, avoiding the situation where the compound fertilizer particles are not cooled thoroughly.
