Atomizer anti-drift method and anti-drift atomizer

Abstract

The invention relates to a structure and a design method of an atomizer applied to agricultural equipment for plant protection, in particular to an anti-drift method of an atomizer applied to miniature motorized agricultural equipment for plant protection and an anti-drift electrostatic atomizer. The anti-drift method of the atomizer comprises the following steps: a. arranging the atomizer which can enable liquid medicine to atomize and spray; b. sleeving an air flow pipe coaxially at the periphery of a fluid pipe of the atomizer and encircling an air flow nozzle at the front end of the air flow pipe at the periphery of a liquid medicine nozzle of the atomizer and using a cyclone device to rotate the air flow before the air low reaches the air flow nozzle; and c. enabling the spray cone angle of the air flow to be larger than the atomization cone angle formed in atomization of the liquid and enabling the spray pressure of the air flow to be larger than the spray pressure of the liquid. The anti-drift method of the atomizer can prevent drift of fogdrops and enhance the atomization application effect. The atomizer has simple structure, small size and good atomization application effect and can prevent drift of fogdrops.

Description

technical field [0001] The invention relates to an atomizing nozzle structure and a design method used in agricultural plant protection machinery, in particular to an anti-drift method for an atomizing nozzle applied to a small motorized agricultural plant protection machinery and an anti-drift electrostatic atomizing nozzle. Background technique [0002] The phenomenon that pesticide liquid droplets drift in the air beyond the non-target area after spraying and spraying is called spray drift. Droplet drift is an inevitable problem in the spraying process. When the droplet drift is serious, the waste caused can reach 70% to 80% of the application amount. Spray drift leads to: (1) wasting pesticides, reducing the control effect, increasing the number of control times, increasing costs and causing excessive spraying; (2) food, air and water pollution caused by excessive pesticide residues; (3) nearby spraying areas The health and life safety of people and livestock are threa...

Problems solved by technology

However, the existing two-fluid electrostatic atomizing nozzles, such as figure 1 As shown (source: Wang Xiaoying, Luo Tiqian, Sha Yi, etc. Charged atomization characteristics of the dual-fluid nozzle. Journal of Jiangsu University (Natural Science Edition), 2007, 28(4): 328-331), its structure and charging method are The following deficiencies: (1) gas enters the nozzle from the axial direction, and the liquid medicine enters the nozzle from the tangential direction. If the lateral wind exceeds 2m / s, the gas and liquid phases will deviate from the target at the same time; (2) the air nozzle is only fixed on the spray body, and the axial position is not designed to be adjustable, which makes it impossible to determine the best axial direction of the air nozzle (3) Charge by adding an electrostatic ring outside the front of the nozzle, because the external electrostatic ring is easy to be adhered by the liquid when the droplets pass through, resulting in short circuit or high voltage breakdown, static electricity Effect and safety are difficult to guarantee
