Description

Technical Field

[0001] The utility model relates to the technical field of material mixing, in particular to a fertilizer mixing device. Background Art

[0002] Generally, a fertilizer mixing device is composed of a mixing tank, a motor, and a stirring shaft structure. When mixing various types of fertilizers, the existing mixing device often cannot efficiently mix the fertilizers, resulting in a problem of a long mixing time.

[0003] In order to solve such problems, Chinese patent CN115445480B, a fertilizer efficient mixing device points out that the single-rotation torque transmitted by the transmission component is converted into two rotational forces in opposite directions through a bevel gear reversing component, so that the outer stirring component and the inner stirring component can achieve synchronous and opposite rotation; the outer stirring component and the inner stirring component rotate synchronously and oppositely, so that the inner and outer layer liquids can be mixed clockwise and counterclockwise respectively under the rotation of the stirring blades. This structure is similar to the coaxial inversion structure in the present application. Although the mixing efficiency is improved, it cannot achieve high mixing efficiency.

[0004] Secondly, Chinese patent CN111939824A, a mixed fertilizer stirring device points out that a vibration mechanism performs a vibration operation on the received material, and a discharge port that can be opened and closed is provided at the bottom of the vibration mechanism. The discharge port is opened for unloading and sending the material to the first stirring rod for stirring, so the mixed fertilizer can be broken up before stirring to improve the subsequent stirring quality; and because the shapes of the first stirring blade and the second stirring blade are different from each other, two different stirring effects can be produced on the fertilizer, thereby greatly improving the stirring quality. Although this structural setting can speed up the mixing of the fertilizer, it is also impossible to achieve high mixing efficiency.

[0005] Therefore, in order to improve the mixing efficiency of fertilizers and achieve efficient mixing, a fertilizer mixing device is proposed. Utility Model Content
