Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pesticide spraying unmanned aerial vehicle, and particularly relates to a pesticide spraying unmanned aerial vehicle. BACKGROUND

[0002] In the field of agricultural plant protection, unmanned aerial vehicle pesticide spraying has become an important operation mode. The traditional unmanned aerial vehicle pesticide spraying system usually adopts a high-pressure pump cooperating with an atomizing nozzle to atomize the pesticide liquid and then sprays it from a high altitude, and the pesticide liquid is blown to crops by the downwash airflow (wind force generated by the self-locking propeller) of the unmanned aerial vehicle. However, this spraying mode has the following technical defects.

[0003] 1. Since the unmanned aerial vehicle flies at a high altitude, the kinetic energy of the downwash airflow generated by the propeller significantly attenuates with the increase of the distance, so that it is difficult for the atomized pesticide liquid to obtain sufficient kinetic energy to penetrate the dense planting layer of crops, which will make the atomized pesticide liquid mainly deposit on the upper leaves or the surface of the crop canopy, and it is difficult to effectively penetrate to the middle and lower parts of the crops (the lower branches and leaves of trees or the stem area of crops), resulting in poor disease and pest control effect.

[0004] 2. Since the atomized pesticide liquid is prone to drift under the influence of wind, especially in windy weather, part of the pesticide liquid may be blown away from the target area, which not only reduces the utilization rate of the pesticide, but also may pollute the surrounding environment or non-target crops.
