Problems solved by technology

[0003] In the existing fertilizer applicators, there are generally disadvantages of low integration, cumbersome operation, low sensitivity, and low control precision.
In terms of EC and flow automatic control, some use Venturi with high-frequency electromagnetic valve, the control effect of this control method is not accurate enough; some use frequency converter to control the speed of quantitative pump to control the flow of fertilizer solution. The control method, EC and flow control are not particularly accurate, and the cost of the quantitative pump is also relatively high

Abstract

The invention discloses an intelligent water and fertilizer integrated machine, which comprises a power distribution cabinet, a main water pump, a plurality of fertilizer injecting pumps, a plurality of fertilizer inlet electromagnetic valves, a plurality of electromagnetic flow meters, a plurality of fertilizer branch pipes and a fertilizer main pipe; the lower ends of the fertilizer branch pipes are respectively connected with a fertilizer sucker through the fertilizer injecting pumps; a fertilizer filter is arranged on each fertilizer sucker; the fertilizer inlet electromagnetic valve is arranged on each fertilizer sucker; the electromagnetic flow meter is arranged on each fertilizer branch pipe; the other end of the fertilizer branch pipe is connected with the fertilizer main pipe; the lower end of the fertilizer main pipe is connected to a fertilizer-water mixing pipeline, a water inlet is formed in the right end of the fertilizer-water mixing pipeline, the left end of the fertilizer-water mixing pipeline is connected to a static mixer, and the left end of the static mixer is connected with a water outlet. The intelligent water and fertilizer integrated machine is reasonable in design, compact in structure, simple to operate, high in sensitivity and control precision, and capable of realizing precise addition of four fertilizers, thus achieving stable fertilizer addition quantity and being intelligent in system.

Description

technical field [0001] The invention relates to the technical field of intelligent equipment, in particular to an intelligent water and fertilizer integrated machine. Background technique [0002] Fertigation refers to an advanced fertilization method that injects the solution containing fertilizer into the drip irrigation system through the fertilization device, and fertilizes the crops together with the drip irrigation water. Its advantages are uniform fertilization, accurate positioning, and simplicity. The irrigation and fertigation system can control parameters such as irrigation water volume, fertilization amount, fertilization time, and fertilizer solution irrigation concentration stably and with high precision, so as to improve the utilization rate of water and fertilizer, and effectively reduce the pollution of soil and environment caused by fertilization. The application method of water-soluble fertilizer is very simple. It can be fertilized along with the irrigati...
