Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer coating, in particular to automatic coating equipment for granular fertilizer. Background Art

[0002] Trace element fertilizers refer to fertilizers containing trace element nutrients, such as boron fertilizer, manganese fertilizer, copper fertilizer, zinc fertilizer, molybdenum fertilizer, iron fertilizer, chlorine fertilizer, etc. They can be simple compounds containing one trace element, or they can be compound fertilizers and mixed fertilizers containing multiple trace and macronutrients. Finished fertilizers need to be coated before packaging, and granular fertilizers need to be coated with a layer of oil film on their surface for anti-caking. The purpose is to prevent the fertilizer from agglomerating after a long time of bagging, and to increase the brightness of the fertilizer surface. By coating, wrapping, adding inhibitors, etc., the decomposition and release time of the fertilizer is prolonged, which is conducive to improving the utilization rate of fertilizer nutrients, thereby achieving the purpose of extending the effective period of the fertilizer and promoting agricultural production. However, in the automatic coating equipment for granular fertilizers currently used, the fertilizer is accumulated in a tank, the fertilizer is easy to agglomerate, and sticks to the inner wall of the tank, so that the coating liquid cannot be evenly applied to the fertilizer surface, resulting in poor coating effect.
