[0026] In order to make the purpose, technical scheme and advantages of the present application more clear and understandable, the present application will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0027] Example 1

[0028] As shown in Figures 1-2 , Figure 6 , the present embodiment proposes a fertilizer coating spraying device, mainly comprising a liquid supply main pipe 1, a plurality of spray heads 2, a support frame for supporting the liquid supply main pipe 1, a liquid supply assembly (such as a liquid supply pipe, a liquid supply pump, a storage tank) for supplying liquid to the liquid supply main pipe 1, the specific structure of the liquid supply assembly (such as the specific model of the liquid supply pump, the volume of the storage tank) should be determined according to the actual liquid supply demand (the liquid supply demand is affected by factors such as the number of spray heads 2, the length of the liquid supply main pipe 1, etc.), and the present embodiment will not be described here.

[0029] Among them, the liquid supply main pipe 1 mainly comprises a plurality of pipe bodies 11 and a plurality of connecting pieces 12, each connecting piece 12 is rotatably connected between each adjacent pipe body 11 and communicates with the pipe body 11, each spray head 2 is fixedly connected to each connecting piece 12 one by one and communicates with each connecting piece 12, that is, the connecting piece 12 is a three-way structure, and the spray head 2 fixedly arranged thereon can be displaced by the rotary connection between the connecting piece 12 and the pipe body 11, so as to realize the adjustment of the spraying range of the spray head 2, so that the spraying range of the spray head 2 can fully cover the moving path of each fertilizer particle moving along the roller, thereby ensuring that each fertilizer particle can be attached with the coating oil sprayed by the spray head 2, and then this batch of fertilizer particles do not need to be coated again, effectively improving the fertilizer coating efficiency.

[0030] In order to improve the sealing between each pipe body 11 and the connecting piece 12, a rotary joint 13 is arranged between each pipe body 11 and the connecting piece 12, so as to prevent the liquid flowing along the pipe body 11 from flowing out of the connecting gap between the pipe body 11 and the connecting piece 12 with the rotation of the connecting piece 12, thereby ensuring the stability of the liquid conveying of the embodiment.

[0031] Meanwhile, in order to facilitate the adjustment of the position of the spray head 2 by the staff, the embodiment is provided with a steering mechanism 3 for controlling the rotation of each spray head 2, that is, the staff can realize the adjustment of the position of the spray head 2 by controlling the steering mechanism 3, thereby effectively improving the convenience of the use of the embodiment.

[0032] The steering mechanism 3 comprises a rotating shaft 31, a rotating motor 32 and a plurality of linkage members 33. The rotating shaft 31 is linked with the output shaft of the rotating motor 32, and each linkage member 33 is fixedly connected to the rotating shaft 31. In this way, by starting the rotating motor 32, the rotating motor 32 drives the rotating shaft 31 to rotate, thereby driving each linkage member 33 located on the rotating shaft 31 to rotate synchronously. Each connecting piece 12 is linked with each linkage member 33, and the linkage relationship between each connecting piece 12 and each linkage member 33 enables each connecting piece 12 and the spray head located on each connecting piece 12 to be adjusted synchronously, thereby ensuring that each spray head 2 can match the distribution of the fertilizer particles in the drum, and eliminating the coverage blind area (such as the inside of the particle accumulation layer or the edge of the drum) caused by the fixed spray head.

[0033] The rotating motor 32 should be fixedly arranged on the support frame, so as to ensure that the rotating motor 32 can stably provide driving force.

[0034] Preferably, each linkage member 33 in the embodiment is a gear. Correspondingly, each connecting piece 12 comprises a linkage portion 121, and each linkage member 33 is engaged with each linkage portion 121 one by one. That is, the embodiment drives the connecting piece 12 to rotate by means of gear transmission and engagement, and by virtue of the constant transmission ratio of the gear transmission, the staff can control the adjustment angle of each spray head 2 by controlling the output of the rotating motor 32 (the rotation angle of the output shaft of the rotating motor 32), which helps to improve the accuracy of the adjustment of each spray head 2.

[0035] Meanwhile, the rotating motor 32 in the embodiment should be preferably a servo motor or other motor with accurate output, which further improves the accuracy and precision of the adjustment of each spray head 2.

[0036] In order to prevent the length of the rotating shaft 31 from being too long, causing the rotating shaft 31 to be easily deformed when being driven by the rotating motor 32, and causing the strength of the rotating shaft 31 to be reduced, the support frame in the embodiment is provided with a support seat 4, and the rotating shaft 31 is rotationally connected to the support seat 4, that is, the support seat 4 is provided with a rotating hole for matching the rotating shaft 31, and the support seat 4 can provide intermediate support for the rotating shaft 31, thereby improving the stability of the rotating shaft 31 during rotation. The support seat 4 should be provided with several, and each support seat 4 is arranged in sequence along the axial direction of the rotating shaft 31, further improving the stability of the rotating shaft 31 during rotation.
