Flexural pivot sleeve 51 and 13 ball-joint of undercarriage have any freedom degree, more flexible；One end of spring supporting bar and outer spray boom 22
Be fixedly connected, the other end protrudes into flexural pivot sleeve 51, by friction and 22 gravity of outer spray boom component realize spring supporting bar it is steady
Surely it is fixed in flexural pivot sleeve 51.
It specifically, further include power assisting device 6, power assisting device 6 includes accessory drive component 61 and traction element 62, and auxiliary is driven
Dynamic component 61 is fixedly installed on the fuselage 1；62 one end of traction element connect with accessory drive component 61, the other end and outer spray boom 22
Connection deforms driving device 23 and accessory drive component 61 simultaneously during outer 22 rotary motion of spray boom to horizontal position
Work, accessory drive component 61 drive traction element 62 to move, and pull the outer upward rotary motion in perpendicular of spray boom 22, from
And move to horizontal position for outer spray boom 22 and lift is provided, the peak torque that Reducing distortion driving device 23 is subject to extends deformation
The service life of driving device 23, reduces the manufacturing cost of deformation driving device 23, and practicability is stronger.
In the present embodiment, accessory drive component 61 is stand-by motor, is fixedly mounted on 1 lower section of fuselage, control system
For controlling the rotation of accessory drive component 61；Traction element 62 is wirerope and idler wheel, is pulled by wirerope and idler wheel outer
The upward rotary motion of spray boom 22 is to horizontal position.
Specifically, interior spray boom 21 fastens close connection by close scored card with undercarriage 13, for undertaking maximum moment；It is logical
Close scored card button is crossed, interior spray boom 21 can rotate in a vertical plane movement relative to fuselage 1, to be folded up income fuselage
1 side or drops down play the role of folding entire spray boom 2, so that the occupancy for reducing interior spray boom 21 is empty to horizontal position
Between, transport easy to carry.Outer spray boom 22 is folded by first with interior spray boom 21 and is snapped connection, and outer spray boom 22 can be relative to interior spray
Bar 21 realizes transverse direction folding of the outer spray boom 22 relative to interior spray boom 21 around the axis rotary motion perpendicular to interior 21 length direction of spray boom
