[0002] Compound fertilizer is a kind of fertilizer with high nutrient content and many main nutrient elements. It can supply more than two elements to crops in one application to meet the nutrients needed for crop growth. Through stirring, the nutrient distribution of compound fertilizer is more uniform. Compared with powdered or crystalline unit fertilizers, its structure is compact, with fewer by-components and less damage to the soil. When compound fertilizer is stirred, it is easy to agglomerate due to the different physical and chemical properties of the raw materials. When using a stirring device, the agglomerated fertilizer is easy to stick to the inside of the box, and ordinary stirring devices are not equipped with a scraping mechanism, which affects the stirring effect and the normal use of the stirring device.

The second gear 204 is rotatably arranged inside the housing 201, the second gear 204 is meshed with the first gear 203, and the second gear 204 is rotatably arranged inside the housing 201 through a bearing. When the motor 3 drives the housing 201 to rotate, the housing 201 drives the second gear 204 to rotate around the first gear 203, and because the second gear 204 is meshed with the first gear 203, the second gear 204 is simultaneously rotating. The rotating shaft 202 is vertically arranged below the second gear 204. Preferably, the top of the rotating shaft 202 can be directly fixedly connected to the second gear 204.
