The atomized liquid medicine can be effectively attached to the surfaces of the fruit branches and leaves by means of static electrification, so that the effective deposition rate of the liquid medicine fog drops is further improved, and pesticide waste and environmental pollution caused by the drift of the fine liquid medicine fog drops are reduced. In addition, the charged atomized liquid medicine also has a tip effect and a wrapping effect, the tip effect can enable the liquid medicine fog drops to be deposited on the surfaces of the branches, and the wrapping effect can enable the liquid medicine fog drops to be deposited on the front surface and the back surface of the blade.

However, there is a certain disadvantage in electrostatic spraying of the liquid medicine, namely that the penetration of the charged fog drops to the canopy of the branches and leaves of the fruits is poor, and in order to ensure sufficient penetration and effective adhesion of the inner branches and leaves of the fog drops, the axial flow fan 13 is additionally arranged, the branches are disturbed by the airflow generated by the axial flow fan, and meanwhile, the fog drops can have stronger penetration under the action of the airflow. In this embodiment, the diameter of the impeller of the axial flow fan 13 is 630mm, and the operating speed is 2000 r/min; in order to ensure the stable spraying of the liquid medicine droplets, the liquid pump 3 adopts a diaphragm pump, which has strong working stability.
For the higher fruit tree of whole crown, in order to satisfy the requirement of giving medicine to the poor free of charge to further enlarge the operation scope, need wholly raise nozzle holder 5, specifically upwards stretch out the realization through the piston rod of lift adjustment cylinder 9, simultaneously for making the droplet spray angle most suitable, can realize the adjustment of atomizing nozzle 4 every single move angle and horizontal pivot angle through the electronic pendulum rotary joint between atomizing nozzle 4 and nozzle holder 5. In order to avoid that the atomizing nozzle 4 is not blocked during the operation, multiple filtration can be arranged in the spraying pipeline. When the liquid medicine in the liquid medicine storage tank 2 is replaced by liquid fertilizer, fertilization with the same effect can be realized.
The embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or modifications without departing from the scope of the present invention are intended to be included in the scope of the present invention.
