Plant protection unmanned aerial vehicle with spray-head switching and accurate spraying functions

Abstract

The invention relates to a plant protection unmanned aerial vehicle with spray-head switching and accurate spraying functions. The plant protection unmanned aerial vehicle comprises a main body, a propeller, a landing gear, an adjusting mechanism and a switching mechanism, wherein the adjusting mechanism comprises a first motor, a first gear, a second gear, a telescopic frame, a slide block, a lifting plate and two moving units, and the switching mechanism comprises a fixed block, a lifting assembly and a switching assembly. According to the plant protection unmanned aerial vehicle with the spray-head switching and accurate spraying functions, through the adjusting mechanism, spray-heads can be stored and protected, and the influence of wind speed on sprayed pesticides can be reduced, so that the pesticides sprayed by the spray-heads are more concentrated, and the unmanned aerial vehicle can spray conveniently and accurately. Through the switching mechanism, the two spray-heads can becontrolled to switch for spraying work, so that a standby role is played when the unmanned aerial vehicle cannot carry out spraying work after one spray-head is damaged, the working efficiency and spraying effect are prevented from being affected, and the practicability and reliability of the plant protection unmanned aerial vehicle are greatly improved.

Description

technical field [0001] The invention relates to the field of plant protection drones, in particular to a plant protection drone with the functions of nozzle switching and precise spraying. Background technique [0002] Plant protection drone, also known as unmanned aerial vehicle, as the name implies, is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft is composed of three parts: a flying platform, a navigation flight control, and a spraying mechanism. Control, to achieve spraying operations, you can spray chemicals, seeds, powder and so on. [0003] However, there are still some deficiencies in the actual use of existing plant protection drones. For example, the nozzles of existing plant protection drones are almost all exposed to the outside, which can easily cause damage to the nozzles. During the spraying process, once the nozzle fails, it will affect the spraying work, which will affect the growth of th...

Problems solved by technology

[0003] However, there are still some deficiencies in the actual use of existing plant protection drones. For example, the nozzles of existing plant protection drones are almost all exposed to the outside, which can easily cause damage to the nozzles. During the spraying process, once the nozzle fails, it will affect the spraying work, which will affect the growth of the plants. In addition, when it is necessary to spray precisely for some special plants, the wind generated by the downward propeller of the drone is too large , the agent sprayed by the nozzle will be blown away, resulting in the inability to concentrate the agent, thereby reducing the effect of spraying. These problems have greatly reduced the practicability and reliability of the plant protection drone
