Description

Technical Field

[0001] The utility model relates to the technical field of blending devices, in particular to a dry blending device for preparing blended fertilizers. Background Art

[0002] Blended fertilizer, also known as formula fertilizer or BB fertilizer, is a mixture of various raw materials made of two or more single fertilizers or compound fertilizers with similar particle sizes, mixed in a certain proportion by simple mechanical mixing. This kind of fertilizer is generally mixed and used by farmers according to the soil nutrient status and crop needs. The advantage of blended fertilizer is that it can be formulated according to different crops, different yields, different soil types, and even different plots of land, avoiding the waste caused by insufficient nutrients or excess nutrients in general fertilization, which is conducive to improving fertilizer utilization and saving costs and increasing efficiency.

[0003] The production process of blended fertilizer is relatively simple and does not require a complex chemical reaction process like compound fertilizer, so the production cost is relatively low. At the same time, the production of blended fertilizer can be flexibly adjusted according to market demand to meet the needs of different users.

[0004] The existing dry mixing device puts the powder to be mixed into it, and achieves the purpose of mixing by mixing and crushing the waste materials inside. However, when the raw materials are stirred and crushed, it is inevitable that some lumps cannot be fully crushed. If these lumps are directly used for irrigation without being processed, it will affect the fertilizer efficiency and plant growth.

[0005] Therefore, it is necessary to provide a dry mixing device for preparing blended fertilizer to solve the above technical problems. Utility Model Content
