Technical Field

[0002] The new type of fertilizer is also called compound fertilizer. Compound fertilizer refers to a fertilizer containing two 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.

[0003] A Chinese patent publication (publication number: CN218250036U) discloses a novel automatic controlled quantitative proportioning device for fertilizer production, which includes a mixing drum and a moving plate, the outside of the mixing drum is fixedly connected with a rotating wheel, one side of the rotating wheel is movably connected with a linkage box, one side of the linkage box is fixedly connected with a motor B, the bottom of the linkage box is fixedly connected with a support frame, one side of the mixing drum is fixedly connected with an output box, one side of the output box is fixedly connected with a motor A, one side of the mixing drum is fixedly connected with an input box, and the top of the moving plate is fixedly connected with a hydraulic press;

[0004] The device controls the size of the fertilizer output port through a pneumatic telescopic rod to achieve the purpose of controlling the dosage of different fertilizer ratios. However, in actual use, the outlet size is controlled by the telescopic rod, and the fertilizer is discharged by freely sliding down. The discharge speed of the fertilizer cannot be controlled, resulting in a certain error in the discharged fertilizer ratio. Compound fertilizers with uneven ratios will have problems such as nutritional imbalance and inhibition of plant growth, which reduces the effect of fertilizers in promoting plant growth. Therefore, a control ratio device is proposed. Utility Model Content
