Air-assisted spraying device based on unmanned aerial vehicle

Abstract

The invention discloses an air supply spraying device based on an unmanned aerial vehicle. The device comprises a flight mechanism, a connecting rod, a nozzle and a liquid storage cavity, wherein the nozzle is fixed on the flight mechanism through the connecting rod, the nozzle is connected with the liquid storage cavity, the liquid storage cavity is installed on the flight mechanism, and the air supply spraying device further comprises a control system and an air supply mechanism, the air supply mechanism is connected with a connecting arm of the flight mechanism, the nozzle and the air supply mechanism are both located between two groups of rotors of the flight mechanism, the air supply mechanism comprises a duct, an air duct, a steering engine set and a supporting frame, the duct is connected with the air duct, the lower end of the air duct is connected with the steering engine set, and the steering engine set is connected with the connecting arm through the supporting frame; and the duct and the steering engine set are connected with the control system. According to the air supply spraying device, under the interaction of existing rotor airflows of the air supply mechanism and the flight mechanism, when the spray head sprays, a steering engine set in the air supply mechanism rotates back and forth, so that liquid spray drifts obviously in the air, the residence time of the spray in the air is prolonged, and the deposition area of the spray is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural disinfecting operations, in particular to an air-driven spraying device based on an unmanned aerial vehicle. Background technique [0002] The existing technology of spraying pesticides, fertilizers and other liquids by drones is becoming more and more mature, and has been widely recognized by the society and vigorously promoted. However, in the existing UAV air-supplied spraying device, the UAV is used to spray the liquid medicine, and the time for the liquid medicine to stay in the air is longer, and the deposition range of the medicine liquid is wider, so as to achieve a better sterilization and disinfection effect. in development stage. At this stage, most of the spray air supply devices are mainly used on the ground, with large volume and heavy equipment. There are very few studies on spray air supply equipment applied to drones. Use the existing drone to spray the liquid to disinfect ...

AI Technical Summary

Problems solved by technology

Use the existing drone to spray the liquid to disinfect the germs in the air, because the liquid sprayed by the nozzle will soon settle down under the action of the rotor flow field of the drone, and it is far from reaching the kill As a result, the effect of killing bacteria and mosquitoes after drone spraying is not obvious
