On the left of connecting respectively inside and outside close two grades of spray boom frame ends of one-level spray bar frame or right side one-level spray bar frame, unilateral leveling liquid
Stretching for adjusting left spray bar frame or the right spray bar frame balance relative to ground of pressure cylinder piston bar；
Described air curtain system includes blower fan, air duct, windbag, screw cooling oil pipe and hydraulic motor；Between air duct and middle spray bar frame
It is provided with air curtain air-flow angle adjustment oil cylinder；Being provided with three hinged supports on front side of air duct, three hinged supports constitute isosceles triangle,
Two hinged supports in lower section are hinged on the middle spray bar frame of existing boom sprayer, and top hinged support is adjusted with air curtain air-flow angle
Whole oil cylinder piston rod end is hinged；Air curtain air-flow angle adjustment cylinder tube end is connected on the middle spray bar frame of boom sprayer, wind
Curtain air-flow angle adjustment oil cylinder is used for adjusting between air curtain system air outlet airflow direction and the shower nozzle spraying droplet direction of motion folder
Angle beta size；Angle β is adjustable in the range of 0-30 °；Described assembling is above air duct, and blower fan is axial flow blower, by hydraulic pressure horse
Reaching driving, blower fan is arranged above air inlet；Air duct is symmetrically arranged on two with two windbags；Windbag has elasticity, and windbag material is impermeable
The cloth of gas；Be provided with the circular exhaust vent of a diameter of 20-40mm immediately below windbag and air duct at interval of 100-300mm, blower fan produces
Raw high velocity air to both sides windbag through air duct uniform distribution, is then discharged through circular exhaust vent, is coerced droplet and fly to target, from
And reduce droplet drift；High velocity air can make droplet secondary-atomizing, improves droplet coverage rate on target；Windbag is arranged over
Spacing hole, is used for limiting windbag position；Described screw cooling oil pipe is the steel hydraulic oil pipe that thermal diffusivity is good, is arranged on fan
Below leaf；Screw cooling oil pipe is for dispelling the heat to existing boom sprayer section hydraulic pipeline；
Spray bar frame direction is provided with multiple windbag stopping means, windbag stopping means include support, spring buckle I, elastic threads I, bullet
Spring buckles II and elastic threads II；Described support is installed in rotation on left spray bar frame and right spray bar frame；Spring buckles I one end can
Being articulated in mid-stent actively, the other end is fixed with elastic threads I；Elastic threads I other end spacing hole corresponding to above windbag is even
Connect；Spring buckles II one end and is articulated in movably on support external part, and the other end is fixed with elastic threads II；Elastic threads II another
End is fixed on left spray bar frame and right spray bar frame；Spring buckle I and elastic threads I for limiting windbag upper-lower position；Left spray bar frame
Buckle II with right spray bar frame, support, spring, one closed loop of composition such as elastic threads II, be used for limiting windbag front and back position；Windbag limits
Position device is elastic device, and after blower fan is opened, windbag is inflated, and windbag stopping means limits in elastic threads I, II elastic range
Before and after windbag and right position, when blower fan close, spray bar frame fold time, holder pivots thus shrivelled windbag is pressed in spray bar frame
On；
Described left spray bar frame or right spray bar frame cross section are in " A " font structure, and shower nozzle is arranged on spray bar frame " A " font knot in company with spray boom
Bottom structure on crossbearer, spray boom and shower nozzle are formed effectively protection, prevent shower nozzle and spray boom from launching at spray bar frame, folding or worked
Journey sustains damage；Shower nozzle on middle spray bar frame is arranged on the bottom of middle spray bar frame in company with spray boom；
Described windbag two ends diameter is different, and it is major diameter that windbag is connected one end with air duct, is minor diameter away from air duct one end,
Thus maintain windbag various places inside pressure constant, make lower section air outlet blast, air quantity consistent.
