[0002] Compound fertilizer refers to a chemical fertilizer containing two or more nutrients. Compound fertilizer has the advantages of high nutrient content, few by-components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yields of crops. In the preparation of compound fertilizer, the selected multiple component raw materials need to be evenly mixed according to the preset ratio, and then made into granules through granulation equipment. Therefore, compound fertilizer manufacturers need to use mixing and blending devices to evenly mix the multiple component raw materials of compound fertilizer.

[0003] For example, the utility model patent with patent number CN201921584556.4 discloses an anti-caking fertilizer mixing device for compound fertilizer production, including a base, on which are provided a feeding device, an auxiliary material adding device, a conveying pump A, a mixing box A, a stirring motor A, a stirring shaft A, a stirring paddle A, a crushing knife A, a discharge port, a crushing device, a mixing box B, a hydraulic cylinder, a stirring motor B, a nozzle and an inner wall cleaning device. This anti-caking fertilizer mixing device for compound fertilizer production can stir fertilizers at different heights in the mixing box by combining a hydraulic cylinder and a stirring motor, thereby improving the mixing effect; at the same time, the provision of an inner wall cleaning device on the mixing box can prevent the fertilizer from adhering to the inner wall, making it easier to clean the mixing box; finally, the crushing device and the alternating stirring paddles A and crushing knives A can eliminate the caking phenomenon of the fertilizer and also make the fertilizer mixing more uniform.
