[0002] Compound fertilizer is a chemical fertilizer containing any two or three of the crop nutrient elements nitrogen, phosphorus, and potassium, which is made by chemical methods or (and) mixing methods. In the production of compound fertilizers, soil nutrient conditions are mostly measured using soil testing and formulated fertilization. Soil testing and formulated fertilization is based on soil testing and fertilizer field trials. According to the fertilizer requirements of crops, soil fertilizer supply performance, and fertilizer effects, on the basis of reasonably applying organic fertilizers, the application amounts, fertilization periods, and application methods of fertilizers such as nitrogen, phosphorus, potassium, and medium and trace elements are proposed. Generally speaking, it is to scientifically apply formulated fertilizers under the guidance of agricultural technicians. The core of the soil testing and formulated fertilization technology is to adjust and resolve the contradiction between crop fertilizer requirements and soil fertilizer supply.

[0035] The material coming out of the spiral-arranged crushing blades 7 and the spiral-arranged crushing steel plates 8 falls into the crushed aggregate hopper 15 and the crushing discharge hopper 16. When the material needs to be recycled for crushing, it is then introduced into the rotary crushing auger 3 through the crushing discharge hopper 16 close to the side of the rotary crushing auger 3, and enters the crushing feed hopper 5 again for crushing under the conveying of the rotary crushing auger 3. The material that does not need to be recycled for crushing can be directly discharged from the crushing discharge hopper 16.

[0036] In the present utility model, the device combines extrusion, rough crushing and fine crushing, so that the compound fertilizer material entering the device can achieve the crushing effect. Compared with the conventional crushing device, the use of the rotary auger enables the material to be recycled for crushing, greatly improving the crushing efficiency. Through the single-motor multi-drive mode, the cost reduction and efficiency increase of the device are realized, and the economic benefit during the crushing of the device is improved. By using the buffer material as the support pad, the buffering, vibration reduction and noise elimination of the device are effectively realized, and the overall use effect of the device is improved.
