When the medicine mixing method of embodiment 1 is executed by using the micro-pressure injection-based online medicine mixing device of the present embodiment, the control module may further obtain a pressure value in the medicine mixing unit 5 from the pressure sensor, and when the pressure value is lower than a set micro-pressure threshold, adjust the water flow rate of the water taking module and the medicine flow rate of the medicine taking module so that the pressure value in the medicine mixing unit 5 is equal to or higher than the set micro-pressure threshold; can keep mixing the medicine through pressure sensor regulation and the pressure that keeps in mixing the medicine unit 5, keep the minute-pressure to mix the medicine for water and liquid medicine volume unchangeable can the misce bene again, has practiced thrift the cost, easy operation, and the mixing accuracy is high.
In this embodiment, the control assembly can also be externally connected with a display screen and an input unit, so that an operator can timely know the numerical values of each flow sensor and each liquid level sensor, the existing medicine mixing ratio, the pressure value and the like, and can manually adjust the parameters.
In conclusion, the on-line uniform mixing of the liquid medicine and the water can be realized according to the actual spraying requirement, the liquid medicine proportioning range is large, and the liquid medicine can be accurately adjusted within the range of 300: 1-3000: 1. Mix the medicine under the minute-pressure state, avoid water and medicine to produce the volume change, improve liquid medicine ratio precision, satisfy the demand of accurate dispensing, reduce the residue of pesticide, and this device can realize mixing the medicine on line in real time, avoids the pesticide extravagant, reduces environmental pollution.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
