Preparation device system of soil conditioning powder

Abstract

The invention provides a preparation device system of soil conditioning powder. The system comprises a central processing unit, a crushing mechanism, a mixing mechanism, a batching mechanism, an activation mechanism, a cooling mechanism, a coating mechanism, a packaging mechanism and a conveying mechanism. A metering valve accurately weighs crushed raw material powder and conveys the raw materialpowder to a stirrer, the metering valve accurately weighs the cooled raw materials and then conveys the raw materials to the coating mechanism, and a dosage controller controls the injection quantityof slow-release powder and auxiliary powder according to precise proportion. Compared with an existing preparation system of soil conditioning powder, the novel preparation system of the soil condition powder can know the content of the raw materials accurately when transferring the raw materials during preparation, so that the injection quantity of the auxiliary powder and the slow-release powderis controlled, errors are reduced, and the quality of the soil conditioning powder is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of preparation devices, in particular to a soil conditioning powder preparation device system. Background technique [0002] Soil conditioning powder is a product made of natural minerals as the main raw material after high-temperature calcination and extraction. It has extremely remarkable three soil conditioning properties of "water retention, fertilizer increase, and ventilation". It can break soil compaction, loosen soil, improve soil air permeability, reduce soil heavy metal pollution, promote soil microbial activity, and enhance soil fertilizer and water penetration; it can improve soil, control deserts, water conservation and drought resistance, enhance crop disease resistance, increase crop yield, improve The quality of agricultural products, the restoration of the original ecology of crops and other functions, greatly increase the survival rate of tree planting and the output of agricultural product...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a soil conditioning powder preparation device system, which aims to solve the problem of adding auxiliary powder and slow-release powder during the preparation of the soil conditioning powder currently on the market. When the raw materials are transferred between various preparation devices, the A certain amount of raw materials will remain in each preparation device, so that the capacity reaching the lower preparation device is smaller than the actual dosage. In the prior art, it is difficult to accurately measure the raw materials in real time during the preparation process, so that the ratio of auxiliary powder and sustained-release powder is too large. Problems that greatly affect the quality of soil conditioning powders
