Low-cost and high-load specialized plant-protection unmanned aerial vehicle and driving method

Abstract

The invention relates to a low-cost and high-load specialized plant-protection unmanned aerial vehicle and a driving method. The unmanned aerial vehicle comprises a flight mechanism, a posture controlling mechanism and a pesticide spraying system which are arranged on a rack, wherein the flight mechanism provides power output for the taking off and landing of the unmanned machine and adjustment of the flight height of the unmanned machine, wherein a posture adjustment mechanism is used for adjusting the aviation and the flight posture of the unmanned aerial vehicle to ensure that the unmanned aerial vehicle is positioned on a scheduled operation route; the pesticide spraying system is used for controlling the pesticide spraying system to spray the pesticide when the plant-protection unmanned aerial vehicle arrives at the scheduled operation area. According to the plant-protection unmanned aerial vehicle and the driving method, transversal type reversed rotation dual rotors driven by an engine are adopted, lift force of a height direction of the unmanned aerial vehicle is provided, and the unmanned aerial vehicle is high in loading capability, long in working time and high in working efficiency; once two pairs of power-driven small rotors are adopted, the thrust required by adjustment of horizontal direction posture and the operation flight of the unmanned aerial vehicle are provided, and the driving of the unmanned aerial vehicle in a three-dimensional space is completely decoupled. The unmanned aerial vehicle has the advantages of simple structure and control principles, convenience in repairing, easiness in learning of remote control operation, and low use and maintenance cost.

Description

technical field [0001] The invention relates to the field of agricultural aviation plant protection, in particular to a low-cost and high-load plant protection drone and a driving method dedicated to agriculture and forestry plant protection, which are used to prolong the working time and reduce the difficulty of operation and control of the drone. Background technique [0002] Plant protection remote control drones are mainly used for spraying and spraying of food or economic crops in large areas of forest or farmland. The high-speed downwash airflow generated by the high-speed rotating rotor can realize the secondary atomization of the droplets ejected from the nozzle, improve the entrainment ability of the droplets, improve the penetration of the liquid medicine, and have a good effect on the control of diseases, insect pests and weeds, etc. Advantages, and it can be operated by remote control at a long distance, so that the remote operator can avoid exposure to pesticide...
