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 be suitable for specific field operation tune
Save spray head spacing.Before aerial sprays operation, spray boom 2 is located in the vertical rod piece of arched door before undercarriage 1 by spacing adjusting device 4
On, spray boom 2 is collapsed in undercarriage two sides.According to parameters such as specific field plant and line-spacings, selects suitable spray head 3 and axially move
Two sides spray boom 2 is moved to obtain suitable spray head spacing.After the completion of spacing adjustment, spray boom 2 is expanded to 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 is inserted into 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 locating plate 5, while spray boom tight loop 11 compresses spray boom 2, makes spray boom 2
Axial position, i.e. 3 spacing of spray head are fixed.That is aerial sprays job position.It tightens holding screw 10 and fixes spray boom, that is, fix
3 position of spray head.Other side spray boom is similarly.
Electrostatic atomization system is as shown, static switching is located at low-pressure end.Static switching is connected, diaphragm pump 18, medicine are started
Liquid 20 flow to diaphragm pump 18 by the road from medicine-chest 16, and 18 outflow port of diaphragm pump connects triple valve 19, draws two medicine liquid outlets: wherein
One outlet accesses high-field electrode, and the polarity of electrode of two sides electrostatic atomization system access is on the contrary, high-field electrode access port is filled in
Son seals, and prevents medical fluid from this mouthful of outflow；It is another outlet be medical fluid connect outflow conduit 20, when medical fluid flows through pipeline 20, electrode with
Medical fluid contact, the medical fluid outflow conduit of triple valve 19 are connected to spray head 3, make electrification of water spray.Hydraulic system and electrostatic generator fortune
After row is normal, start to carry out spraying operation.After operation, holding screw 10 is extracted, spray boom 2 is collapsed into undercarriage two sides,
Spray boom tight loop 11 unclamps, and spray boom 2 restores axial adjustability.
