[0002] Compound fertilizer is a kind of fertilizer containing multiple main plant nutrients and other trace elements. Compared with single element fertilizers, it can provide multiple nutrients required by plants, thereby more comprehensively meeting the needs of plant growth. A major advantage of compound fertilizer is that it can be formulated according to the nutrient requirements of different crops and soils to meet the growth requirements of specific plants. Its use can improve the efficiency of plant nutrient absorption, promote plant growth, improve crop quality and increase yield.

[0003] In the production process of compound fertilizer, its raw materials need to be measured and proportioned to control the supply ratio of different nutrients in order to achieve the expected fertilization effect. The commonly used ingredient metering method is to manually feed the materials onto a weighing machine to weigh the weight of each raw material in a certain proportion. In this way, the accuracy and speed of human operation are limited, resulting in low weighing efficiency. In addition, each raw material is weighed separately and not mixed together. Subsequently, the raw materials need to be put into a mixing equipment to mix multiple raw materials, which is extremely troublesome to operate.

[0004] Therefore, a batching metering scale for compound fertilizer production is proposed to solve the above problems. Utility Model Content

[0026] Preferably, as another embodiment of the utility model, the positioning mechanism includes a screw rod 71, a motor 72, a connecting plate 73, and a support rod 74. The connecting plate 73 is horizontally provided inside the box body 2, and the back sides of the multiple rectangular frames 6 are connected to the front side of the connecting plate 73. The motor 72 is fixedly connected to both sides of the inner rear wall of the box body 2.

Finally, the transmission shaft 8 will drive the spiral blade 12 to rotate to generate a downward propulsion force and discharge the raw materials out of the discharge barrel 11.
