Mixing device for composite bio-fertilizer production and use method of mixing device

Abstract

The invention discloses a mixing device for composite bio-fertilizer production and a use method thereof, the mixing device comprises a mixing cavity and a motor base arranged on one side of the mixing cavity, wherein the other side of the mixing cavity is provided with supporting legs, and the middle position of the lower end of the mixing cavity is provided with a discharge pipe; a material screening barrel which is arranged in the mixing cavity, one end of the material screening barrel is provided with a first material screening cavity, the other end of the material screening barrel is provided with a second material screening cavity, the middle position of the material screening barrel is provided with a crushing cavity, the inner diameter of the crushing cavity is provided with material guiding internal threads, and a grinding plate is arranged between the material guiding internal threads; a crushing mechanism which is arranged in the material screening barrel, wherein a stirring shaft groove is formed in the crushing mechanism; the mixing device realizes the effect of simultaneously crushing and mixing materials, so that the problem that the mixing effect is influenced due to the difference of the diameters of various particle materials is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a mixing device for producing compound biological fertilizers and an application method thereof. Background technique [0002] Compound biological fertilizer refers to biological products containing a variety of beneficial microorganisms. The advantage of this fertilizer is that it has a comprehensive effect, which can not only improve crop nutrition, but also promote growth, resist disease, and enhance soil biological activity. At the same time, various bacterial species can promote each other. Therefore, the adaptability and stress resistance of compound biological fertilizers are very strong, and the fertilizer effect is durable and stable, which is the direction of the development of biological fertilizers in the future. Existing studies have combined a microbial fertilizer with other nutrients, such as mixing with macronutrients, trace elements, rare earth e...

AI Technical Summary

Problems solved by technology

Existing studies have combined a microbial fertilizer with other nutrients, such as mixing with macronutrients, trace elements, rare earth elements or plant growth regulators, etc., but regardless of the compounding method, attention must be paid to the compounding Neither the pH in the formulation nor the salt concentration nor the formulation itself can affect the survival of the microorganisms, otherwise the formulation will fail

[0003] At present, when the mixing devices for fertilizer production on the market are used, the diameters of various granular materials are different, which affects the mixing effect. When using them, an additional crushing device is required to deal with the problem that will increase the production cost and affect the mixing of the mixing device. efficiency
