According to the operation mode of the granulation nozzle, it can be divided into a static granulation nozzle and a rotating granulation nozzle. When spraying and granulating the fertilizer melt, the raw material melt is generally input into the granulation nozzle of the granulation tower for spraying. After natural cooling during the falling process, particles are formed to achieve the granulation effect.

The heat dissipation fan 20 can be used to blow air to cool the sprayed raw material particles while avoiding passing through the side of the nozzle 5.

[0033] It should be noted that the wind blown by the cooling fan 20 can blow the particles sprayed from the side of the nozzle 5 downward, reducing the moving distance of the particles sprayed from the side of the nozzle 5, and preventing the particles from hitting the side of the box 1 and affecting the use effect.

[0034] As attached Figure 1 As shown, the lowest end of the unloading guide plate 2 corresponds to the discharging guide plate 3, and a unloading port is provided on the side of the box body 1 close to the discharging guide plate 3, and the unloading port corresponds to the lowest end of the unloading guide plate 2 and the position of the discharging guide plate 3. A feeding pipe 24 is provided at the position corresponding to the storage barrel 4 on the top of the box body 1, and a dustproof net 25 is provided around the top of the box body 1.

[0036] At the same time, the rotation of the rotating rod 7 can drive the scraper plate 12 and the scraper plate 11 to rotate, scraping the side, inside and bottom of the nozzle 5, so that the raw material sprayed through the discharge hole 6 can be discharged in granular form, and the discharge hole 6 can be prevented from being blocked, thereby improving the use effect.

[0037] As attached Figure 1 and 2 As shown, the rotation drive mechanism includes a gear ring 13 fixed to the outer surface of the storage barrel 4, and transmission gears 14 are arranged around the gear ring 13.

The storage barrel 4 can be controlled to rotate by cooperating with the gear ring 13. The cooperation of multiple transmission gears 14 and the connecting rod 16 can improve the stability of the rotation of the storage barrel 4 and improve the use effect.

[0040] The working principle of the utility model is as follows: when in use, the raw materials are fed into the interior of the storage barrel 4 through the feed pipe 24, and then the second motor 15 and the first motor 8 are started. The second motor 15 controls the storage barrel 4 and the nozzle 5 to rotate, and the first motor 8 controls the rotating rod 7 to drive the stabilizing rod 9, the stirring plate 10, and the scraper 11 to rotate;

[0041] The storage barrel 4 drives the nozzle 5 to rotate so that the raw materials can be sprayed out through the discharge hole 6.

When the rotating rod 7 rotates, the stabilizing rod 9 can improve the rotation stability of the rotating rod 7, thereby improving the use effect.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
