Atomization system provide medicinal liquid.Medicinal liquid flow to membrane pump by the road from medicine-chest, and two membrane pump outflow conduits draw one respectively
Three-way valve, one goes out head piece and is connected to shower nozzle by pipeline in spray boom, does not contact with external fuselage；It is another go out head piece be used for access height
Piezoelectricity pole.
Electrostatic generator enters shown in Figure 10, and both sides high tension generator low pressure termination unmanned plane carries DC source, high pressure
A pole extraction electrode is held to be placed in three-way valve, another pole is connected on unmanned plane undercarriage.Both sides system access threeway valve electrode
Opposite polarity, one positive one is negative.The wire being connected on unmanned plane is also one positive one negative, charging neutrality, solves unmanned machine operation powered
Problem.Electrostatic spray can improve the uniformity of aerial sprays, reduce drift.Present invention achieves shower nozzle in aviation electrostatic spray
Spacing regulation problem.Aerial sprays working performance is improved, the aerial sprays suitability is improved, operating time and material cost is reduced.
Further, sprinkler spacing is adjusted by the axial movement of spray boom, and shower nozzle is fixed with respect to spray boom position, adjusts spray
During head spacing, medicinal liquid pipeline walks circulation in spray boom, reduces external influence.
Further, be provided with static switching, disconnect after switch can direct shower nozzle needed for replacement operation, it is convenient and simple.
Further, as sprinkler spacing is adjustable, it is possible to achieve operation of the unmanned plane under Different Crop environment.
Different from the atomization system structure that existing plant protection unmanned plane nozzle position is fixed, the present invention is to meet spray boom foldable
While stretching, extension is readily transported, solve the problems, such as that medicinal liquid pipeline adjusts sprinkler spacing under current intelligence in spray boom.Make plant protection
Unmanned plane can be adjusted to the sprinkler spacing for needing according to practical situation, improve aerial sprays when spraying operation is performed
The suitability.

Specific embodiment
In farmland operation, the line-spacing of plant size and plantation is had nothing in common with each other, and should select to adjust suitable for concrete field operation
Section sprinkler spacing.Before aerial sprays operation, spray boom 2 is positioned at the vertical rod member of arched door before undercarriage 1 by spacing adjusting device 4
On, spray boom 2 is drawn in undercarriage both sides.According to parameters such as concrete field plant and line-spacings, move from suitable shower nozzle 3 and axially
Dynamic both sides spray boom 2 is obtaining suitable sprinkler spacing.After the completion of spacing adjustment, spray boom 2 is expanded to into job position.Undercarriage is fixed
There is gap between position part 14 and the pressing plate of spray boom tight loop 11, when holding screw 10 inserts the positioning spiral shell of 11 pressing plate of spray boom tight loop
When hole is tightened, 11 two panels pressing plate of spray boom tight loop is adjacent to spacer 5, while spray boom tight loop 11 compresses spray boom 2, makes spray boom 2
Axial location, i.e. 3 spacing of shower nozzle are fixed.That is aerial sprays job position.Tighten holding screw 10 and fix spray boom, that is, fix
3 position of shower nozzle.Opposite side spray boom is in the same manner.
Electrostatic atomization system is as illustrated, static switching is located at low-pressure end.Static switching is connected, starts membrane pump 18, medicine
Liquid 20 flow to membrane pump 18 by the road from medicine-chest 16, and membrane pump 18 goes out head piece and connects three-way valve 19, draws two medicine liquid outlets：Wherein
One outlet accesses high-field electrode, and the polarity of electrode that both sides electrostatic atomization system is accessed is conversely, high-field electrode access port is filled in
Son is sealed, and prevents medicinal liquid from flowing out from this mouthful；Another outlet connects outflow conduit 20 for medicinal liquid, when medicinal liquid flows through pipeline 20, electrode with
Medicinal liquid is contacted, and the medicinal liquid outflow conduit of three-way valve 19 is connected to shower nozzle 3, makes electrification of water spray.Hydraulic system and electrostatic generator fortune
After row is normal, spraying operation is proceeded by.After operation is finished, holding screw 10 is extracted, spray boom 2 is collapsed to into undercarriage both sides,
