Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, in particular to a coating machine for producing slow-release fertilizer. Background Art

[0002] The release rate of chemical nutrients in slow-release fertilizers is much lower than the release rate of instant fertilizers that are converted into plant-available nutrients after being applied to the soil. The most common method of producing slow-release fertilizers is to cover the outer surface of the fertilizer with a protective film. Therefore, when processing slow-release fertilizers, a coating machine is required to coat the slow-release fertilizers.

[0003] In the Chinese patent with publication number CN209307253U, a slow-release fertilizer coating device is disclosed, which adopts a cradle-type coating method, in which the fertilizer core rolls irregularly in a rocking plate, prolongs the coating time, makes the coating layer more completely coated, reduces the coating failure rate, and improves the fertilizer efficiency; however, when the above-mentioned slow-release fertilizer coating device coats the fertilizer core by rotating the rocking plate clockwise or counterclockwise, the fertilizer core is easily ejected from the rocking plate by the centrifugal force, causing the fertilizer core to scatter into the production equipment, thereby causing the fertilizer core to be wasted and increasing the production cost. Therefore, we propose a coating machine for producing slow-release fertilizers. Utility Model Content

[0004] The utility model provides a coating machine for producing slow-release fertilizers, so as to solve the problem that when coating the fertilizer cores in the existing coating device, the fertilizer cores are easily ejected from the shaking plate by centrifugal force, so that the fertilizer cores are scattered in the production equipment, resulting in waste of the fertilizer cores and increased production costs.

[0011] Preferably, the two first limiting plates and the two second limiting plates are arranged in a cross shape around the diagonal rod, and multiple limiting rods and the two first limiting plates and the two second limiting plates are spliced ​​to form a square outer frame. Through the cooperation of the positioning rod and the second limiting plates, the diagonal rod can rotate around the outside of the positioning rod.

[0012] Preferably, a positioning shaft is provided on the top of the support plate, and the first limiting disk is sleeved on the positioning shaft. Through the cooperation of the limiting rod and the second limiting disk, the limiting rod drives the first limiting disk to rotate around the positioning shaft.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] (1) Through the cooperation of structures such as the swing device and the limit mechanism, the inclined rod drives the rocking plate to tilt and rotate, so that the fertilizer core inside the rocking plate can rotate irregularly inside the rocking plate, thereby preventing the fertilizer core from flying out of the rocking plate due to the centrifugal force, thereby preventing the fertilizer core from scattering into the production equipment body, avoiding the waste of fertilizer core resources, and helping to reduce the processing cost of slow-release fertilizer;
