Plant-protection unmanned aerial vehicle

Abstract

The invention relates to the field of unmanned aerial vehicles, and discloses a plant-protection unmanned aerial vehicle, including a fuselage, a connecting block, an engine arm, a propeller, a support rod I, a support rod II, landing sticks, a medicine cabinet, a propeller motor, a spray motor, a swing lever, a spray tube, a drug delivery hose and spray nozzle. The invention can uniformly spray the medicament in the direction of advancement of the unmanned aerial vehicle and the direction perpendicular to the direction of advancement of the unmanned aerial vehicle. The invention also eliminates the blind area of medicament spraying, that is, medicament can also be sprayed under the fuselage of the unmanned aerial vehicle, and the spraying range of the medicament liquid is wider and more uniform through the oscillation of the spraying pipe, so that the phenomenon that medicament cannot be uniformly dispersed due to insufficient height when the aircraft flies in the ultra-low altitude is prevented.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a plant protection unmanned aerial vehicle. Background technique [0002] In recent years, unmanned aerial vehicles (UAVs) have been widely used in civilian fields, especially in the field of crop plant protection. The use of unmanned ultra-low-altitude plant protection light small aircraft has high operating efficiency, small amount of spraying per unit area, no need for special take-off and landing airports, With the advantages of good mobility and other advantages, the current spraying methods of plant protection drones are mostly low-altitude and ultra-low-altitude operations. The liquid is evenly attached to the surface of the crops, and the operation process of the UAV is directly directed by the flight controller through the source distance remote control or by the ground control tower. At the lower end of the rotor, the wind blown by the rotor is used to spray the...

[0002] In recent years, unmanned aerial vehicles (UAVs) have been widely used in civilian fields, especially in the field of crop plant protection. The use of unmanned ultra-low-altitude plant protection light small aircraft has high operating efficiency, small amount of spraying per unit area, no need for special take-off and landing airports, With the advantages of good mobility and other advantages, the current spraying methods of plant protection drones are mostly low-altitude and ultra-low-altitude operations. The liquid is evenly attached to the surface of the crops, and the operation process of the UAV is directly directed by the flight controller through the source distance remote control or by the ground control tower. At the lower end of the rotor, the wind blown by the rotor is used to spray the liquid medicine evenly while spraying. However, when the UAV is flying at low altitude, no matter how strong the wind is blowing the liquid medicine, the liquid medicine will not be sprayed because the height is too low. It is also too late to disperse evenly in the air, resulting in the lower area of ​​the drone fuselage not being able to spray the liquid medicine, and because the nozzle is always set vertically to the ground, when flying at low altitude, the ground will be sprayed due to the uneven spraying. Not enough area
