[0002] Compound fertilizer refers to a 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 yield of crops. However, it also has some disadvantages. For example, its nutrient ratio is always fixed, while the types, quantities and proportions of nutrients required by different soils and crops are diverse. Therefore, it is best to test the soil before use to understand the texture and nutritional status of the field soil. In addition, it is also necessary to pay attention to the application with unit fertilizers to get better results. With the continuous improvement of the level of mechanical automation, automatic control technology is increasingly used in compound fertilizer packaging production.

[0028] The working principle of the utility model is as follows: first, place the container bag on the second tray 514, manually press the control switch 511, and start the electric telescopic rod 52 through the wire control to drive the closing plate 56 to open, so that the fertilizer in the silo 7 is discharged into the container bag through the discharge port 9, and the container bag presses the second tray 514, and the second tray 514 is pressed downward linearly due to the increase in the weight of the fertilizer through the linear limit of the damper 513 and the elastic characteristics of the spring bar 515. When the weight of the fertilizer increases to the preset weight, the trigger rod 516 at the bottom of the second tray 514 touches downward, and The trigger control switch 511 is pressed, and the control switch 511 controls the electric telescopic rod 52 to start through the wire, so that the transmission block 54 at the output end of the electric telescopic rod 52 moves forward, so that the two connecting arms 55 on the transmission block 54 drive the two closing plates 56 to slide through the outer surface of the limit rod 53, and the protruding part of the left closing plate 56 is inserted into the notch part of the right closing plate 56, so that the two closing plates 56 are completely filled and closed on the inner wall of the closing hole 8, sealing the opening for the fertilizer to be discharged downward, and then taking out the mouth of another container bag and putting it on the discharge opening 9, taking away the container bag with enough amount on the second supporting tray 514, and repeating the operation.
