Fully-automatic metering bacterium-adding system for fertilizer particles

Abstract

The invention provides a fully-automatic metering bacterium-adding system for fertilizer particles, and relates to the field of bacterium adding systems of fertilizer production. The fully-automatic metering bacterium-adding system comprises a bacterial powder supply system, a fertilizer particle supply system, an organic matter supply system and a powder applying cylinder; the bacterial powder supply system comprises an upper hopper, a lower hopper and a bacterial powder conveying pipe which are sequentially connected up and down, and the bacterial powder conveying pipe is provided with an electromagnetic oscillator; the fertilizer particle supply system comprises a fertilizer conveying belt, a fertilizer storage hopper, a conveying motor and a screw conveyor which are sequentially connected up and down; and the organic matter supply system includes a humic acid conveyor belt, a stevia rebaudiana powder conveyor belt, a water pipe, an organic matter storage hopper, a powder metering pump and an organic matter conveyor belt which are sequentially connected up and down. The fully-automatic metering bacterium-adding system provided by the invention has a high automation degree and accurate measurement and realizes uniform metering and adding of bacterial powder; and the number of strains for a single fertilizer particle is consistent, a survival rate of the strains is greatly improved, and needs of automated production of bacterial fertilizers can be met.

Description

technical field [0001] The invention relates to the field of bacteria adding systems for fertilizer production, in particular to a fully automatic metering and adding bacteria system for fertilizer granules. Background technique [0002] Over the years, due to partial application, single application, and heavy application of chemical fertilizers, the pH of the soil has changed, the content of organic matter has decreased, the soil has been severely compacted, water retention, fertilizer retention, and air permeability are extremely poor, and the beneficial microbial flora in the soil has decreased greatly, making the soil Neutral ions produce antagonism, so the growth of plants is malnourished, the damage of pests and plant physiological diseases is increasing year by year, and the yield of crops is generally low. [0003] Bacterial fertilizer refers to a specific product containing living microorganisms, which is used in agricultural production. Since bacterial fertilizer c...

Problems solved by technology

[0004] In the process of bacterial fertilizer production, adding bacteria evenly to fertilizer granules is an important link, but we found the following defects in the existing fertilizer granule adding bacteria system: 1. The bacteria are not evenly injected, and there are too many bacteria. Or too little problem; 2. The number of bacteria in a single fertilizer granule is inconsistent; 3. After adding bacteria to fertilizer granules, the survival rate of the bacteria is low
