Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer preparation, and particularly relates to a stirring and packaging device for fertilizers. Background Art

[0002] Fertilizers are compounds that help plants grow. There are a great variety of fertilizers sold on the market. Among them, compound fertilizers are chemical fertilizers containing any two or three of the crop nutrient elements nitrogen, phosphorus, and potassium, which are made by chemical methods or mixing methods. Their function is to meet the comprehensive needs and balance of multiple nutrients required by agriculture under different production conditions.

[0003] Therefore, in the production process of compound fertilizers, different raw materials need to be put into a stirring device for stirring and then transferred to a storage device for packaging. Among them, some raw materials of compound fertilizers have high solubility, so during the stirring process of the raw materials, it is very easy to have the phenomenon of material caking and adhesion, forming lumps of different sizes, resulting in insufficient and uneven dispersion of the raw materials, thus affecting the fertilizer efficiency of compound fertilizers. The caked fertilizers will also affect the subsequent fertilization of fertilizers.

[0004] At present, the commonly used stirring device on the market is that a stirring shaft is installed in the middle of a stirring barrel. However, this stirring structure can only stir the materials in the horizontal direction. For the vertical direction, it is very difficult to stir the materials in the lower layer to the upper layer, which also leads to insufficient dispersion of the materials at the bottom of the stirring barrel and serious caking.

[0005] In view of this, this application is specifically proposed. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is that the commonly used stirring device is that a stirring shaft is installed in the middle of a stirring barrel. However, this stirring structure can only stir the materials in the horizontal direction. For the vertical direction, it is very difficult to stir the materials in the lower layer to the upper layer, which also leads to insufficient dispersion of the materials at the bottom of the stirring barrel and serious caking. The purpose is to provide a stirring and packaging device for fertilizers. By setting an up-and-down flipping structure and combining it with a dispersion mesh barrel structure, the materials in the device can be fully mixed and dispersed, and the materials at various positions in the entire box body can be fully exchanged and dispersed in position, greatly improving the stirring quality of the materials and ensuring the fertilizer efficiency of fertilizers.

[0007] The utility model is realized through the following technical solutions:
