Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer coating, in particular to a coating device for preventing fertilizer caking. Background Technique

[0002] In agricultural production, in order to make fertilizers exert the maximum fertilizer efficiency, a layer of film is often coated on the surface of fertilizer particles, that is, the so-called coated fertilizer. The purpose of coating is to make the quick-acting nutrients inside the coated fertilizer slowly release after being applied to the soil, so as to extend the fertilizer efficiency.

[0003] According to the patent document with the authorization announcement number: CN220056679U and the name of "a fertilizer coating device", this new type includes a multi-prismatic roller composed of two side plates and several side plates, a pipeline for transporting liquid, and a feeder for transporting particles. The multi-prismatic roller is driven to rotate by a driving mechanism. The pipeline is connected to the side of the feeder. The pipeline and the feeder extend into the multi-prismatic roller. An adjustable scraper mechanism for scraping off the attachments on the inner wall of the multi-prismatic roller is arranged on the inner side of the side plate. In this fertilizer coating device, by setting the multi-prismatic roller and combining with the adjustable scraper mechanism, during the rotation coating process of the fertilizer, the fertilizer attached to the inner wall can be effectively scraped off automatically by gravity, without manual cleaning, saving manpower.

[0004] The fertilizer is transported into the roller by using a feeder, and then the coating liquid is added to coat the fertilizer. However, the fertilizer is not convenient to screen and use in the roller, resulting in the accumulation and caking of some fertilizers, uneven coating, affecting the processing efficiency of fertilizer coating. At the same time, the coating liquid pipe body only sprays the liquid at the nozzle end, resulting in a limited spraying area, reducing the practicability of the fertilizer film device and the fertilizer film processing.

The motor is turned on to drive the roller 1 to rotate, and the screening cylinder 201 rotates synchronously. During the rotation of the screening cylinder 201, the coating liquid coats the periphery of the fertilizer. After coating, the sizes of the fertilizers are different. By turning on the electric push rod 208, the electric push rod 208 passes through the roller 1 and is connected to the mounting seat 207. The mounting seat 207 is arranged on the arc-shaped plate 206. The arc-shaped plate 206 is correspondingly arranged on the periphery of the screening cylinder 201, so that the arc-shaped plate 206 is opened. The larger coated fertilizers are discharged through the extension cylinder 205 as qualified ones, and the smaller fertilizers are discharged into the roller 1 through the screening holes 202. At the same time, the coating liquid flows into the roller 1 through the screening holes 202. The coating liquid can also be added into the roller 1 through the liquid inlet assembly 4 arranged at one end of the roller 1 to achieve secondary coating processing of the fertilizer, and then discharged through the opening at the other end. By arranging the arc-shaped plate 206 inside the roller 1 and on the periphery of the screening cylinder 201 and closing the arc-shaped plate 206, the roller 1 and the screening cylinder 201 can separately perform coating processing on the fertilizer.
