Solid fertilizer continuous dissolving and injecting all-in-one machine and control method thereof

Abstract

The invention relates to a solid fertilizer continuous dissolving and injecting all-in-one machine and a control method thereof. The solid fertilizer continuous dissolving and injecting all-in-one machine comprises a grinding device, a feeding device and a dissolving chamber, wherein the feeding device communicates with a feeding port of the grinding device; the dissolving chamber communicates with a discharging port of the grinding device; and the dissolving chamber is provided with a water inlet hole and a fertilizer outlet hole lower than the water inlet hole. The machine can be specially used for rapidly dissolving a soluble solid fertilizer and injecting a fertilizer liquid into an irrigation system, so that water and fertilizer integrated management is realized, and the blank of water and fertilizer management mechanization is made up; procedures of grinding and crushing, small-water dissolution, repeated circulating dissolution promotion through suction, flushing and spraying, three-stage filtration and fertilizer injection of the solid fertilizer are completed in sequence, the fertilizer dissolving and fertilizer injection processes are continuous, and the mechanical working efficiency is remarkably improved; a multi-chamber continuous filtering device can realize dissolving and mixing of the solid fertilizer in a short time, so that the stability of the concentration of the output fertilizer liquid is improved; and the flushing nozzles push liquid in all the cavities to rotate and flow at the same time, the liquid is mutually blended, and fertilizer dissolution andfertilizer liquid uniform mixing are remarkably accelerated.

Description

technical field [0001] The invention relates to the field of integrated water and fertilizer machinery, in particular to a solid fertilizer continuous dissolving and injection integrated machine and a control method thereof, which are suitable for supporting use with irrigation facilities such as micro-spray irrigation, drip irrigation, and sprinkler irrigation. Background technique [0002] The integration of water and fertilizer is an important technical approach to realize water-saving irrigation and efficient management of water and fertilizer. It has been widely valued in arid and semi-arid water-deficient areas in my country, and the area of ​​promotion and application is gradually increasing. [0003] At present, the integrated management of water and fertilizer in production mostly uses special water-soluble fertilizers. However, the production cost of this kind of water-soluble fertilizer is often high, the price is expensive, and the formula is relatively fixed, an...

AI Technical Summary

Problems solved by technology

It is necessary to take auxiliary measures such as continuous stirring and shaking to help the fertilizer dissolve, which not only increases manpower input, but also is difficult to meet the needs of large-scale production. There is an urgent need for a method that can quickly dissolve solid fertilizer to form a uniform fertilizer solution, and then inject the fertilizer solution into the irrigation system of the facility. mechanical device
