More rotor plant protection drones were risen recent years, due to its stability, mobility, and not by characteristics such as the influences of topography, by
Gradually it is applied to agricultural plant protection, pesticide spraying, the sprinkling of leaf fertilizer etc..
The spray pattern of mainstream at present：The sprinkling of direct-injection, i.e. nozzle vertically downward
Such as wheat rice etc., when carrying out pesticide spraying to these conventional crops, the direction of nozzle generally only need straight down, by
Intensive in crop, major part of spraying can be received by crop.Short smooth crop, it is easy to be curved by wind, when using direct-injection,
The front of leaf is easy by medicine, and really seldom by medicine, the sprinkling of this spray pattern, referred to as direct-injection, is current mainstream at leaf back
Spray pattern.When being sprayed to tall and big fruit tree leaves, according to the spray pattern of direct-injection, back is by medicine due to leaf angle
Degree, it is few by dose；And the insect pest of crops is all largely at the back of leaf, at this moment direct-injection is extremely difficult to disappear to insect pest
It goes out effect.
For the improved spray pattern of direct-injection：Tiltedly spray, the i.e. sprinkling of nozzle diagonally downward
It is all sprinkling angles by powder product only plant vertically in the projected area on ground if using direct-injection by taking fruit tree as an example
Degree is by powder product minimum, and when using this spray pattern, and pesticide droplet is near vertically falling on leaf, fruit tree plant
Blade be that largely by medicine, the leaf back side is few by medicine in leaf front by medicine situation.
The insect pest of the industrial crops such as fruit tree, vegetables, tea tree is mainly in the leaf back side, direct-injection spray pattern during this time by
Then vertical sprinkling, sprays from tree crown, the back side of leaf is caused to be difficult to by medicine vertically downward.At this time, it needs to adjust nozzle
Angle, the inclined side for being directed toward plant, this spray pattern are called tiltedly spray sprinkling.We improve the angle of nozzle as a result,
Degree, devises the unmanned plane sprinkling system of adjustable nozzle angle.
The insect pest for solving crops blade back is general by the way of oblique spray sprinkling.
But have clearly disadvantageous place when tiltedly spraying nozzle carry below more gyroplanes：
1, pesticide gradient is deteriorated with sprinkling angle：Propeller wind（Mainly vertical wind）Under the action of, tilt the pesticide quilt of sprinkling
Wind changes spray orbit, and under pesticide is rung by wind, the angle of sprinkling also becomes smaller.
2, leaf angle and leaf gap are deteriorated：Under propeller wind action, fruit tree leaf is pushed by wind direction, angle hair
It is raw to change, the gap of leaf（Gap and separated by gap is laminated）Become smaller, pesticide droplet is difficult to enter leaf gap so that leaf is carried on the back
Face cannot be sprayed to；
3, tree branch is difficult to stablize：Fruit tree crotch is more, and branch can be dilapidated under wind effect, due to the toughness of trunk, fruit
Tree branch can acutely shake, and " escape " is by medicine.
