Summary of the invention:
The object of this invention is to provide a kind of agricultural unmanned aerocraft, it forms the unmanned aerocraft of farmland operation by many rotor wing unmanned aerial vehicles, ultrasonic range finder, being organically combined of Power output flexible axle case science.Thus realize plunderring with ground profiling low speed flying, spraying material quantity can regulate with flying speed, meets the technical requirements of agricultural to unmanned aerocraft.
The present invention is achieved in that agricultural unmanned aerocraft comprises upper spider 1, lower bearing bracket 2, mid frame 3, coaxial positive and negative oar rotor head 4, traction screw propeller 5, traction screw propeller motor 6, flight attitude propeller blades 7, flight attitude propeller blades motor 8, rotatablely crank arm 9, vertical tail 10, secondary battery 11, receiver 12, steering wheel 13, electricity adjusts device 14, ultrasonic range finder 15, farm implements articulated device 16, Power output flexible axle case 17, outer safety guard net 18, tubulose medicine-chest 19, supporting leg 20.
Described upper spider 1, mid frame 2, lower bearing bracket 3, tubulose medicine-chest 19, supporting leg 20 grafting are combined into the frame of agricultural unmanned aerocraft.The each flight attitude propeller blades in front, rear, left and right 7 and flight attitude propeller blades motor 8 are mechanically connected to rotatablely to crank arm on 9 and to be collapsiblely arranged on upper spider 1 top, and steering wheel 13 is arranged on upper spider 1 rear portion and vertical tail 10 is mechanically connected; Described traction screw propeller 5, traction screw propeller motor 6 are mechanically connected with Power output flexible axle case 17 and are arranged on the front portion of mid frame 3; Described coaxial positive and negative oar rotor head 4 is arranged on mid frame 3 in even number symmetric offset spread; Described outer safety guard net 18 is arranged on mid frame 3 outside; Described secondary battery 11, receiver 12, electricity adjust device 14, ultrasonic range finder 15, farm implements articulated device 16 are arranged on the top of tubulose medicine-chest 19 and are fixed on lower bearing bracket 3; Device 14, ultrasonic range finder 15, coaxial positive and negative oar rotor head motor 23, traction screw propeller motor 6, flight attitude propeller blades motor 8 is adjusted to electrically connect secondary battery 11, receiver 12, steering wheel 13, electricity.
The flight attitude balance of aerocraft realizes by four, front, rear, left and right on remote control upper spider 1 flight attitude propeller blades 7, advance realizes by traction screw propeller 5, Altitude control controls the relative height with ground by ultrasonic range finder 15 by the rotating speed controlling coaxial positive and negative oar rotor head 4, and crashproof is that the rotation of leaning on ultrasonic range finder 15 to control traction screw propeller 5 realizes.
Aerocraft power supply is supplied by secondary battery or hybrid power power supply, the rotating speed of Power output flexible axle and traction screw propeller motor speed synchronously change, control the quantity that agricultural material shed by farm implements, tubulose medicine-chest 19 not still the container case of pesticide liquid be also lower bearing bracket 2 girder, there is anti-shake dividing plate its inside, and the rocking of liquid when can alleviate flight, ensures to have a smooth flight, farm implements articulated device 16 can be implement quick-attaching couple, and vertical tail controls to turn.
The present invention has following beneficial effect: simple structure, and work efficiency is high, and quality is good, and operating cost is low, safety and environmental protection.
