Background
The plant protection has very key effects on improving the pest control effect of agricultural crops and increasing both production and income, pesticide spraying is generally carried out by using a pesticide spraying machine at present, and a single-fluid high-pressure spray head is generally adopted in an atomization mode or an air blower is additionally arranged for blowing to enable liquid drops to be attached to plant leaf surfaces. The particle size of the liquid drops is generally 20-350 μm, and the liquid drops are too large, so that the penetrability is good, the drift amount is small, the adhesiveness is poor, and the utilization rate of the liquid medicine is low; although the liquid drops are small enough, the adhesiveness is good, the medicine is saved, but the penetrability is poor, and the drift easily causes the phytotoxicity. Agricultural plant protection needs a spraying nozzle which is environment-friendly, has reduced pesticide application amount, good penetrability and small drift amount.
The double-fluid atomization nozzle is widely applied to the fields of metal cooling, disinfection, fire fighting and the like, and the pesticide spraying application is less. The double fluid is generally water and air, and has the characteristics of relatively small granularity of fog drops and good atomization effect. By adjusting different water pressure and air pressure and the mixing ratio of water and air, fog drop particles with different sizes can be generated.
However, the existing two-fluid atomization nozzle used for agricultural plant protection has the following defects: (1) the range is small, and the penetrability of pesticide spraying is poor; (2) the fog momentum is small, the disturbance power to branches and leaves is insufficient, and the drug attachment on the backs of leaves and leaves on the leaves is uneven; (3) the structure is complicated, and gas and liquid are easy to cross.

Preferably, the mounting position of the helical blade is lower than the air inlet.
Preferably, the lower end of the liquid spray nozzle is of a conical structure.
Preferably, the lower end of the air injection nozzle is of a conical structure.
The utility model has the advantages that:
1. the liquid is atomized for the second time to obtain more fine spraying effect. Firstly, high-pressure liquid is sprayed out through a liquid spraying nozzle to obtain primary atomization, and then collides with high-speed gas sprayed out from an air spraying nozzle to complete secondary atomization, so that finer fog drops are formed, larger spraying kinetic energy is obtained, and the spraying distance is increased;
2. high-pressure gas forms rotating gas-liquid mixed fluid at the gas jet under the action of the helical blades, so that the blades of the plants are disturbed and turned over, the leaves and the backs of the leaves can be loaded with the pesticide, and meanwhile, the rotating gas flow enhances the crown penetration capacity of the pesticide;
3. the nozzle base body is in threaded connection with the air injection nozzle, and the size of the air injection nozzle can be adjusted by rotating the air injection nozzle to enable the air injection nozzle to move up and down, so that the size of the spraying angle and the distance of the spraying range can be changed.
5. The structure is simple and compact, the gas cavity and the liquid cavity are mutually independent, the problem of mutual connection of gas and liquid is avoided, the air injection nozzle and the liquid injection nozzle can be conveniently disassembled and replaced with different models according to the use requirement, and the maintenance is easy.
