The effect for setting 10 prevents flusher 10 and collision on the ground.
The droplets particles of atomizing sprinkling in this programme are 30 microns or less.When fogdrop diameter is more than 30um, decrease speed
Comparatively fast, and single droplet weight is larger, and the pushing wind field of aircraft can not make droplet raise up.Fogdrop diameter is too small, such as 2.5um, again
It can suspend, be easily blown to four winds for a long time in the sky.When fogdrop diameter is in 10-30um, decrease speed will not be too fast, flies simultaneously
After the pushing wind field of machine reaches ground, the wind to rebound back can blow afloat upwards the droplet of subsequent arrival, be applied to plant leaf blade
The back side.The fogdrop diameter of the atomizing sprinkling of this programme is small, can be floated in air, is easy by the rebound wind field of aircraft with the short time
It blows afloat upwards.And there is certain flotation time, spray effect can be reached well into leaf gap, the leaf back side is arrived,
Meanwhile the droplet of atomizing sprinkling is smaller, sprinkling more evenly, avoids phytotoxicity to a certain extent.
Since flusher 10 includes atomization unit and secondary-atomizing unit.Wherein, atomization unit includes centrifugal atomizing
Disk 1 and the inlet for being set to 1 one side surface of centrifugal atomizing disk, medical fluid from inlet flow into centrifugal atomizing disk 1, surface from

On several teeth 14, secondary-atomizing unit is coaxially nested with atomization unit, and is set to one of atomization unit far from inlet
Side, the two has gap, to prevent causing to rub when spin-ended turn.Since atomization unit and secondary-atomizing unit coaxially reversely rotate,
So that throwing away to form the minimum droplet of partial size.It passes through first motor 3 and the second motor 4 driving atomization unit and secondary mist respectively
Change unit and realize sprinkling, and first motor 3 and the second motor 4 most preferably reversely rotate, when first motor 3 is clockwise/inverse
Hour hands rotate when, the second motor 4 be counterclockwise/rotate clockwise.Certainly, it is also not necessarily limited to this, first motor 3 and the second motor 4
It can also be with rotating Vortex.
