[0002] Organic fertilizer is a carbon-containing material mainly derived from plants or animals, applied to the soil to provide nutrients to plants. It is processed from biological matter, animal and plant waste, and plant residues, eliminating toxic and harmful substances and enriching it with a large number of beneficial substances, including various organic acids, peptides, and abundant nutrients such as nitrogen, phosphorus, and potassium. It not only provides comprehensive nutrition for crops, but also has a long-lasting effect, increases and renews soil organic matter, promotes microbial reproduction, and improves the physical and chemical properties and biological activity of the soil. It is a major nutrient for green food production. For example, a raw material screening device for blended fertilizers according to Chinese patent application number CN202120010744.7 includes a platform, a screening box fixedly connected to the top of the platform, a mixing box fixedly connected to the top of the screening box, a first discharge port at the lower end of the mixing box, a first switch control valve at the lower end of the first discharge port, a crushing zone inside the screening box, a first fixing plate fixedly connected to the outer left end of the crushing zone, a second fixing plate fixedly connected to the outer left end of the screening box, a vibrating screen fixedly connected to the output end of the vibrating motor, and a storage area below the vibrating screen. In this invention, fertilizer undergoes mixing and initial stirring in a mixing box, crushing in a crushing box, initial screening in a screening section, and secondary screening in a vibrating screen, which greatly improves the screening effect of fertilizer raw materials, reduces labor costs, and significantly increases work efficiency.
