[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] like Figures 1-2 As shown, this embodiment proposes a fertilizer coating oil spraying device, mainly including a chute 1 and a spraying mechanism 2. The spraying mechanism 2 mainly includes a liquid supply pipe 21 and several atomizing nozzles 22. The liquid supply pipe 21 should be equipped with a liquid storage tank, a liquid supply pump, a liquid delivery pipe, and other liquid supply structures. Each atomizing nozzle 22 is located on the liquid supply pipe 21 and is connected to the internal pipeline of the liquid supply pipe 21 to ensure that the coating oil can be moved from the liquid supply structure into the liquid supply pipe 21 and finally sprayed out from each atomizing nozzle 22 to complete the coating oil spraying work. The liquid inlet of the liquid supply pipe 21 should be provided with a connection structure for interconnection with the liquid supply structure. Specifically, how the liquid supply pipe 21 is interconnected with the liquid supply structure should be determined according to the specific structure and model of the liquid supply structure actually selected. This embodiment will not elaborate further (similarly, since this embodiment does not involve any modification to this part of the prior art, the specific structure is not shown in the accompanying drawings).

[0027] The chute 1 includes an inlet 11 and an outlet 12. Each atomizing nozzle 22 is located between the inlet 11 and the outlet 12, allowing the spraying mechanism 2 to spray coating oil onto the particle flow path, ensuring that each particle is coated with the coating oil and completing the particle coating process. The inlet 11 of the chute 1 should be connected to the fertilizer conveying device, such as the guide tube, in the fertilizer coating equipment. The specific connection between the inlet 11 of the chute 1 and the fertilizer conveying device depends on the equipment matched and applied in this embodiment, and will not be elaborated further in this embodiment.

[0028] like Figures 2-3As shown, a support frame 4 is provided at the feed inlet 11. The support frame 4 includes a support ring 41 for cooperating with the liquid supply pipe 21, and several support rods 42 for fixing the support ring 41 to the chute 1. Preferably, both ends of each support rod 42 are welded to the support ring 41 and the chute 1 for fixed connection. That is, the presence of the support frame 4 provides a support point for the end of the liquid supply pipe 21 close to the feed inlet 11, preventing the liquid supply pipe 21 from becoming skewed in the chute 1, and effectively ensuring the stability of the overall structure of this embodiment.

[0029] Each support rod 42 is a cylindrical rod structure, avoiding a planar contact surface between the support rod 42 and the fertilizer particles in the chute 1. This allows the fertilizer particles in contact with the support rod 42 to continue flowing along the surface of the support rod 42, effectively preventing fertilizer particles from getting stuck at the connection interface between the support rod 42 and the chute 1. Preferably, there are two support rods 42, and each support rod 42 is located on the left and right sides of the radial surface of the support ring 41, thereby minimizing the impact of the support rods 42 on the normal flow of fertilizer particles.

[0030] To prevent flow obstruction of fertilizer particles in the chute 1, a stirring mechanism 3 is provided in the chute 1 in this embodiment. Specifically, the stirring mechanism 3 mainly includes a stirring paddle 31 and a stirring motor 32. The stirring paddle 31 is located inside the chute 1 and is rotatably connected to the chute 1. The stirring motor 32 is fixedly installed outside the chute 1, and the output shaft of the stirring motor 32 is linked with the stirring paddle 31. That is, under the action of the stirring motor 32, the stirring paddle 31 starts to rotate, thereby breaking up the fertilizer particles in the chute 1 and effectively preventing the fertilizer particles from clogging each other and causing flow obstruction. Moreover, with the stirring effect of the stirring paddle 31 on the fertilizer particles, the fertilizer particles in the chute 1 can not only flow along the inclination angle of the chute 1, but also tumble under the action of the stirring paddle 31, thereby effectively improving the uniformity of the coating oil sprayed by the oil spraying mechanism 2 on the surface of each fertilizer particle.

[0031] Meanwhile, in order to ensure that the stirring range of the stirring paddle 31 can cover the axial section of the chute 1, and to avoid interference between the stirring paddle 31 and the liquid supply pipe 21, which is also located in the chute 1, during rotation, the stirring paddle 31 in this embodiment includes a clearance hole 311 and a stirring rod 312. The liquid supply pipe 21 is located in the clearance hole 311, and the clearance hole 311 is coaxially arranged with the rotation axis of the stirring paddle 31. In this way, through the hole-axis fit between the liquid supply pipe 21 and the clearance hole 311, interference between the stirring paddle 31 (stirring rod 312) and the liquid supply pipe 21 is effectively avoided as the stirring paddle 31 rotates, ensuring that the stirring mechanism 3 can carry out stirring work stably and continuously.

[0032] Preferably, the stirring paddle 31 is rotatably connected to the liquid supply pipe 21, and the liquid supply pipe 21 provides a support point for the stirring paddle 31, thereby further improving the stirring stability of the stirring paddle 31.

[0033] like Figures 1-2 , Figure 4 As shown, in this embodiment, a linkage structure 33 is provided between the output shaft of the stirring motor 32 and the stirring paddle 31 so that the output shaft of the stirring motor 32 and the stirring paddle 31 are misaligned, which effectively avoids the presence of the stirring motor 32 blocking the liquid inlet of the liquid supply pipe 21, and facilitates the flow of coating oil into the liquid supply pipe 21, ensuring the smoothness of liquid supply.

[0034] Specifically, the linkage structure 33 includes a drive gear 331 and a driven gear 332. The driven gear 332 is a ring gear and is fixedly connected to the agitator 31. The ring-shaped structure of the driven gear 332 facilitates its matching with the clearance hole 311 on the agitator 31, allowing the liquid supply pipe 21 to pass through both simultaneously. The drive gear 331 is linked to the output shaft of the stirring motor 32 and meshes with the driven gear 332. In other words, the linkage structure 33 is implemented through gear transmission, effectively reducing energy loss.

[0035] like Figures 2-5 As shown, in this embodiment, there are several stirring rods 312, and each stirring rod 312 is evenly distributed around the clearance hole 311. That is, by increasing the number of stirring rods 312, the stirring frequency of the stirring paddle 31 on the fertilizer particles is increased.

[0036] Meanwhile, several connecting frames 313 are provided between each stirring rod 312, and each atomizing nozzle 22 is located between each adjacent connecting frame 313 to avoid interference between each atomizing nozzle 22 and each connecting frame 313. The presence of each connecting frame 313 allows each stirring rod 312 to support each other, thereby ensuring the positional stability of each stirring rod 312 in the chute 1 and preventing it from tilting. Specifically, each connecting frame 313 includes a connecting ring 3131 and several connecting rods 3132. Each connecting rod 3132 is fixedly connected to the connecting ring 3131 and each stirring rod 312. The liquid supply pipe 21 is located in the inner ring of the connecting ring 3131. Preferably, each connecting ring 3131 is rotatably connected to the liquid supply pipe 21, so that the liquid supply pipe 21 can serve as a support point for each connecting frame 313, further improving the stability of the stirring paddle 31 in the chute 1.

[0037] Each connecting rod 3132 is a cylindrical rod structure, meaning that the contact surface between the connecting rod 3132 and each fertilizer particle is an arc-shaped surface. This effectively disperses the force exerted on the connecting rod 3132 when the fertilizer particles come into contact with each connecting rod 3132, reducing the impact of these forces on the connecting rod 3132 and improving the structural stability of the connecting frame 313.
