[0020] Please see the attached Figure 1 -Attached Figure 8 A granule coating device for a slow-release fertilizer comprises a box body 1, with an open slot on the top of the box body 1, and further comprising: a discharge box 3, an intermittent discharge component, a rotating component and a coating component. The end of the discharge box 3 is fixedly installed inside the open slot, and the discharge box 3 is communicated with the box body 1. A feed hopper 4 is installed on the top of the discharge box 3. The intermittent discharge component is arranged inside the discharge box 3, and the intermittent discharge component is used to intermittently discharge the fertilizer to be coated. The rotating component is arranged inside the box body 1 and on the discharge box 3, and the rotating component is used to rotate the discharged fertilizer. The intermittent discharge component and the rotating component cooperate to discharge the fertilizer intermittently and rotate.

By setting up the intermittent feeding component, the rotating component and the coating component, the fertilizer can be fed evenly in rows, ensuring that when coating the fertilizer, there will be no obstruction during the spray coating due to excessive feeding. In addition, the fertilizer will rotate when feeding, ensuring the uniformity of the fertilizer spray coating.

[0021] Please see the attached Figure 4 -Attached Figure 8 In a preferred embodiment, the intermittent unloading component includes: a unloading roller 12, which is rotatably arranged inside the unloading box 3, the unloading roller 12 is hollow, and a plurality of evenly distributed discharge grooves 20 are opened on the surface of the unloading roller 12, and a push plate 23 is slidably arranged inside each discharge groove 20, a driving motor 5 is installed on the outside of the unloading box 3, and the output shaft of the driving motor 5 is installed with a rotating shaft, and the other end of the rotating shaft is fixedly installed at the center of the end face of the unloading roller 12; When the fertilizer needs to be coated, the fertilizer is first placed inside the feed hopper 4, and the fertilizer inside the feed hopper 4 will enter the corresponding discharge trough 20. At the same time, the drive motor 5 is started to drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the large pulley 8 and the discharge roller 12 to rotate. The discharge roller 12 rotates through the discharge trough 20 to drive the push plate 23 to revolve.

It should be noted that the fertilizer needs to be screened before coating to ensure the uniformity of the fertilizer and to ensure that there is only one grain of fertilizer inside the discharge trough 20.

[0024] Please see the attached Figure 7 -Attached Figure 8 In a preferred embodiment, each connecting plate 25 is movably mounted with a slide post 29 at both ends, and the slide post 29 is slidably mounted inside the path groove; When the slide post 29 passes through the inclined groove 27 from the first arcuate groove 26 and enters the second arcuate groove 28, the slide post 29 will move in the direction away from the center of the disc 21. The movement of the slide post 29 drives the connecting plate 25, the second spring rod 24 and the push plate 23 to move in the direction away from the center of the disc 21, thereby pushing the fertilizer out of the discharge chute 20 and ensuring the stability of fertilizer discharge.

[0025] Please see the attached Figure 2 and attached Figure 6 In a preferred embodiment, a limit plate is vertically fixedly installed on the top of the box body 1, and a fixed shaft 11 is fixedly installed on the side of the limit plate.
