[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] refer to Figure 1-4 , a fertilizer uniform coating equipment, including a sleeve 1 and a roller 2 rotatably mounted on the sleeve 1, the top of the roller 2 is provided with a feed port 11 connected to the inside of the roller 2, and also includes: a spray part 3, mounted on the top of the sleeve 1, having a spray cavity 31 connected to the feed port 11, atomizing nozzles 33 are mounted on the inner walls on both sides of the spray cavity 31, and the atomizing nozzle 33 is connected to a liquid inlet pipe 34; a discharge part 4, mounted on the top of the spray part 3, having a plurality of feed channels 41 uniformly spaced and laterally distributed, the feed channels 41 are connected to the spray cavity 31; a feed hopper 5, mounted on the top of the discharge part 4, for introducing fertilizer into the feed channel 41.

[0027] It can be understood that the drum 2 is a component for rolling the fertilizer, and gears can be installed here and cooperate with motors to realize the rotation of the drum 2. The spray chamber 31 is a space that is enclosed on all sides except the upper and lower ends. For example, it can be a cube or a sphere, etc., but it is not limited to this. Here, a rectangular spray chamber 31 is preferred. Multiple feed channels 41 are components for uniformly guiding the fertilizer, for example, they can be arranged in a straight line or in an S shape, etc., but it is not limited to this. The feed hopper 5 receives or stores the fertilizer. For example, it can be an inverted trapezoidal structure or a conical funnel structure, etc., but it is not limited to this. It should be noted that the liquid inlet pipe 34 needs to be connected to the oil tank and the pump body, and the pump body is used as a power to draw the coating liquid from the oil tank and spray it out from the atomizing nozzle 33.

[0028] With such arrangement, the fertilizer enters the discharge part 4 from the feed hopper 5, and is separated and discharged through a plurality of feed channels 41. The fertilizer vertically falls into the spray chamber 31 like a waterfall, and then the coating liquid is atomized and sprayed on the fertilizer through the atomizing nozzles 33 on both sides, and the fertilizer finally falls into the drum 2. In this way, the uniformity of the fertilizer coating is improved in the early stage, and the rolling time of the drum 2 is reduced in the later stage, which improves the production efficiency and reduces the probability of the fertilizer being broken due to rolling.

[0029] In some embodiments, reference Figure 3, the liquid spraying part 3 also includes a box body 32, the liquid spraying chamber 31 is located inside the box body 32, and the liquid inlet pipe 34 is installed on both sides of the box body 32. Further, a plurality of atomizing nozzles 33 are arranged horizontally along the inner wall of the liquid spraying chamber 31. Further, the atomizing nozzles 33 on both sides of the liquid spraying chamber 31 are arranged relatively or staggered up and down. It can be understood that the box body 32 is the main structure of the liquid spraying chamber 31. The lateral arrangement of the plurality of atomizing nozzles 33 is consistent with the lateral arrangement direction of the feed channel 41, which ensures that the range of the coating liquid spraying can cover all the fertilizers falling from the feed channel 41. Of course, the atomizing nozzle 33 can also adopt a single nozzle with lateral coverage to all fertilizers.

[0030] In some embodiments, in order to smoothly introduce the fertilizer into the drum 2 , a material guide pipe 6 is installed inside the sleeve 1 , with one end connected to the feed port 11 and the other end pointing to the drum 2 .

[0031] In some embodiments, reference Figure 3-4 , the discharge part 4 also includes a discharge pipe 42, and the feed channel 41 is formed by a plurality of partitions 43 installed at intervals inside the discharge pipe 42. Of course, it can also be directly assembled by multiple conduits. Furthermore, the width of the feed channel 41 is smaller than the width of the spray chamber 31, and is located at the top center of the spray chamber 31. Here, the width of the feed channel 41 is reduced to limit the thickness formed when the fertilizer falls. In this way, the atomized coating liquid can better penetrate the fertilizer layer to prevent the fertilizer in the middle from not receiving the coating liquid.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
