[0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements of nitrogen, phosphorus and potassium. 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] The specification of Chinese patent CN211302770U discloses an automatic feeding device for compound fertilizer production. The utility model is convenient for crushing the raw materials used in production to a certain fineness through the crushing tool. The raw materials crushed to the required fineness can pass through the screen, and the raw material particles that do not reach the required fineness can be crushed by the crushing tool again.

[0004] However, in the actual application process, due to the variety of nutrient elements required by different soils and crops, the types, quantities and proportions of raw materials need to be mixed in different proportions during the production of compound fertilizers. The existing feeding device does not have the function of automatic mixing, and the staff are required to mix manually during production, which reduces production efficiency and is inconvenient for the staff to use.

[0007] In the above-mentioned automatic feeding equipment for compound fertilizer production, the raw materials are weighed according to the required proportion before feeding, and then the weighed raw materials are mixed and introduced into the working cylinder, eliminating the need for manual mixing by staff, thereby improving production efficiency.

[0008] As a further improvement of the present application, two feed hoppers are fixedly connected to the upper end of the fixed cover, the longitudinal section of the guide tube is Y-shaped, the feed hopper is located directly above the guide tube, and the feed hopper, the fixed cover and the guide tube are connected.

[0009] As a further improvement of the present application, the weighing hopper is located directly above the feed hopper, and the weighing hopper is located directly below the storage barrel, and the upper end diameter of the weighing hopper is larger than the lower end diameter of the storage barrel.

[0012] As another improvement of the present application, the outer surface of the storage barrel is fixedly inlaid with glass, and the outer surface of the storage barrel is printed with scale lines.

[0013] To sum up, in actual application, the raw materials are poured into two storage barrels respectively, and after the electric valve three is started to discharge the raw materials in the working cylinder, the electric valve one is started to make the raw materials in the storage barrel fall into the weighing bucket. The weighing bucket moves downward as the weight increases, driving the moving cylinder to move downward, and the spring and the pull rope to stretch downward, so that the weighing device weighs the raw materials in the weighing bucket. When the required weight is reached, the electric valve one is closed and the electric valve two is started to pour the raw materials in the weighing bucket into the feed hopper, and then discharged into the guide pipe through the feed hopper, so that the two raw materials are mixed and discharged into the working cylinder, and the weighing ratio of the raw materials can be completed without manual operation by the staff, which improves the work efficiency and is convenient for the staff to use.
