Description

Technical Field

[0002] Chemical fertilizers, referred to as fertilizers, are fertilizers made by chemical and physical methods that contain one or more nutrients required for the growth of crops. They are also called inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. After the production of fertilizers is completed, the moisture in the fertilizers needs to be dried. The temperature of the dried fertilizers is high, and the fertilizers need to be cooled. At present, most of the existing fertilizer coolers cannot stir the fertilizers inside the box when cooling the fertilizers, and cannot cool the fertilizers evenly, which easily leads to insufficient cooling of the fertilizers, reduced cooling effects, and low cooling efficiency. In addition, the fertilizers are not easy to take out after cooling, which easily causes blockage during discharging, and it is inconvenient to collect and use the cooled fertilizers, which greatly reduces the overall efficiency of fertilizer production. For this reason, we have introduced the following device. Utility Model Content
