Example Embodiment
[0025] Example one
[0026] This embodiment provides a multi-rotor plant protection drone, such as figure 1 As shown, it includes the landing gear 1, the fuselage 2, the frame 3, the arm 4, the main rotor 5, the auxiliary rotor 6, the spray system and the control system. The fuselage 2 is arranged above the landing gear 1 and connected to the landing gear 1. The frame 3 is arranged above the fuselage 2 and connected with the fuselage 2, the arms 4 are installed on the frame 3, the arms 4 are an even number and are symmetrically distributed on the frame 3, and the engine 7 is arranged on the upper part of the frame 3. The main rotor 5 is connected with the output shaft of the engine 7, each arm 4 is provided with an electric motor 8, the output shaft of each motor 8 is connected with the corresponding auxiliary rotor 6, and each arm 4 is provided with a spoiler 9, The spoiler 9 is used to counteract the reaction torque generated when the main rotor 6 rotates. The control system, e...
Example Embodiment
[0028] Example two
[0029] This embodiment provides a multi-rotor plant protection drone, such as figure 1 , 2 As shown, on the basis of the first embodiment, the control system of this embodiment includes an engine control system arranged on the frame 3. The engine control system is communicatively connected with a steering gear 31, and the steering gear 31 is provided with a rocker, The swing end of the rod is connected with one end of a connecting rod, and the other end of the connecting rod is connected with the accelerator of the engine. The engine control system can control the working state of the joystick on the steering gear 31 according to the control signal. The steering gear 31 rotates the end of the joystick connected to it, drives the other end of the joystick to swing, and then drives the connecting rod to move through the swing of the joystick. Thereby, the closing of the throttle is controlled, the air intake of the engine is controlled, and the speed of the mai...
