Problems solved by technology

[0004] (1) The pesticide box is set on the fuselage. Since the motor of the UAV is also set on the fuselage, the vibration of the fuselage is particularly large, causing the pesticide in the pesticide box to shake, which is likely to cause pesticide failure and pesticide failure. Damage to the medicine box, etc.;
[0005] (2) The carrying capacity of the fuselage is limited, so the capacity of the pesticide box is required to be small, and the pesticide box needs to be replenished frequently, which affects the spraying efficiency

Embodiment 1

[0025] This embodiment provides a drone for spraying pesticides, such as figure 1 As shown, the drone for spraying pesticides includes a fuselage 1, a main rotor 2 arranged on the top of the fuselage 1, and a landing gear 3 arranged at the bottom of the fuselage 1. The landing gear 3 includes two frame bodies 31, each frame body 31 is provided with a pesticide box 4 and a spraying device 5. The spraying device 5 includes a frame 51 and three pesticide spray heads 52 arranged on the frame 51 . One end of the bracket 51 is fixed on the frame body 31 , and the other end extends outwards. Three pesticide nozzles 52 are evenly distributed on the bracket 51 along the extending direction of the bracket 51 . The bottom of the fuselage 1 is also provided with a pesticide nozzle 52 communicating with the pesticide box 4 , and the pesticide spraying of the drone can be carried out through the pesticide nozzle 52 .

[0026] The length of the bracket 51 is 2 to 4 times of the width of th...

Embodiment 2

[0031] This embodiment provides a drone for spraying pesticides, such as figure 2 As shown, its basic structure is the same as that of Embodiment 1, including a fuselage 1, a main rotor 2 arranged at the top of the fuselage 1, and a landing gear 3 arranged at the bottom of the fuselage 1. The landing gear 3 includes two frame bodies 31, each frame body 31 is provided with a pesticide box 4 and a spraying device 5. A first lift wing 6 is arranged between the two frames 31 , and the first lift wing 6 is in the shape of a dish protruding toward the fuselage 1 .

[0032] The difference is that the UAV in this embodiment is provided with a second lift 8 above the main rotor 2, the structure of the second lift 8 is basically the same as that of the first lift 6, and it protrudes toward the fuselage 1. dish shape. Through the combination of the first lift wing 6 and the second lift wing 8, the carrying capacity of the UAV can be further improved.

Abstract

The invention provides an unmanned aerial vehicle for pesticide spraying and relates to the technical field of air vehicles. The unmanned aerial vehicle for pesticide spraying aims to solve the problems that existing unmanned aerial vehicles for pesticide spraying are poor in bearing capacity, poor in stability and the like. The unmanned aerial vehicle for pesticide spraying comprises an airframe,a main rotor arranged on the top of the airframe, and an undercarriage arranged at the bottom of the airframe. Frames of the undercarriage are provided with pesticide boxes and spraying devices. A first lifting wing is arranged between the two frames, the first lifting wing is in the shape of a dish raised towards the direction of the airframe, and buffer damping elements are connected between the first lifting wing and the airframe. According to the unmanned aerial vehicle for pesticide spraying, due to the facts that both the pesticide boxes and the spraying devices are arranged on the undercarriage and the buffer damping elements are arranged between the undercarriage and the airframe, influences of shock of the airframe on the pesticide boxes can be effectively reduced, and the stability can be improved; by the adoption of the first lifting wing, the bearing capacity of the unmanned aerial vehicle can be greatly improved, and the spraying efficiency of the unmanned aerial vehiclecan be improved..

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an unmanned aerial vehicle for spraying pesticides. Background technique [0002] At present, the spraying of pesticides to crops is basically manual spraying, which is inefficient, expensive and harmful to the human body. With the advancement of science and technology, there has been a technology of using drones to spray pesticides. The existing drones for spraying pesticides include a fuselage, a pesticide box and a pesticide spray head arranged on the fuselage. The pesticide in the pesticide medicine box is sprayed out, which has high efficiency, uniform spraying and can reduce the harm of the pesticide to the human body. [0003] The existing drones for spraying pesticides have the following problems: [0004] (1) The pesticide box is set on the fuselage. Since the motor of the UAV is also set on the fuselage, the vibration of the fuselage is particularly large, causing th...
