Problems solved by technology

[0003] Therefore, the monitoring of droplet density and particle size is very important in the spraying process of drones, but the technology for measuring droplet density in the market is still immature, and the measurement of mechanical instruments is difficult to operate, and there are many instruments used for large limitations. As a particle size analyzer, it is expensive and inconvenient to carry with the field

preparation example Construction

[0011] The method for preparing aircraft drop test paper provided by the invention, concrete steps are as follows:

[0012] 1) Mix 0-60 parts of EDTA with 0-60 parts of chrome black T evenly, and the mass parts of EDTA and chrome black T are 0 at the same time;

[0013] 2) 0-5 parts of boric acid and 0-5 parts of urea are used as pH regulators;

[0014] 3) Add the pH regulator in step 2) dropwise to the chemical reagent in step 1), and stir at a constant speed;

[0015] 4) Apply the chemical reagent to the test paper and dry it.

Embodiment 1

[0018] 1) Mix 50 μL of EDTA with 500 μL of Chrome Black T;

[0019] 2) No pH regulator is added;

[0020] 3) Stir at a constant speed for about 1 min;

[0021] 4) Apply the chemical reagent to the test paper and dry it for 30 minutes.

[0022] The test paper prepared according to the above method has a purple base color and appears blue when it encounters water.

Embodiment 2

[0024] 1) Mix 50 μL of EDTA with 500 μL of Chrome Black T;

[0025] 2) adding boric acid pH regulator;

[0026] 3) Stir at a constant speed for about 1 min;

[0027] 4) Apply the chemical reagent to the test paper and dry it for 30 minutes.

[0028] The test paper prepared according to the above method has a purple base color and appears blue when it encounters water.

Abstract

The invention belongs to the field of unmanned aerial vehicles and relates to aerial vehicle droplet test paper for measuring droplet density and particle size and a preparation method thereof; the aerial vehicle droplet test paper is prepared from the mixture of one or two of the chemical reagents of chrome black T and EDTA (ethylene diamine tetraacetic acid) in optional ratio, and the chemical reagents are mixed with water and are applied to test paper that is then dried. The aerial vehicle droplet test paper and the preparation method thereof have the advantages of good operational convenience, good convenience of use, wide range of related fields and the like; the aerial vehicle droplet test paper is suitable for use both indoors and outdoors, and it is possible to simply and quickly measure the size and density of droplets through chromogenic reaction of chemical substances on the test paper with droplets.

Description

technical field [0001] The invention belongs to the field of drone spraying, and relates to an aircraft droplet test paper for measuring droplet density and particle size and a preparation method thereof. Background technique [0002] Agricultural UAV UAVs are not restricted by geographical factors, and can successfully and efficiently complete tasks; UAV spraying of medicines and fertilizers is effective and safe, and the downdraft of the rotor can improve the penetration and deposition rate of the liquid medicine , improve the spraying effect; reduce the risk of pesticide poisoning of operators; high degree of automation, relatively few operating crews, and low labor intensity. Therefore, agricultural drones have been popularized in recent years, but the droplet size, coverage density, and concentration of pesticide solutions have a significant impact on the efficacy of insecticides, fungicides, and herbicides. There is an optimal particle size relationship between the dr...
