Description

TECHNICAL FIELD

[0001] The application relates to the technical field of unmanned aerial vehicles, in particular to a foldable pest extermination unmanned aerial vehicle. BACKGROUND

[0002] The mechanical pest extermination unmanned aerial vehicle is an innovative device for pest control based on a physical method, which directly eliminates or drives away pests through mechanical means, thereby reducing the dependence on chemical pesticides. Such unmanned aerial vehicles are usually equipped with high-speed rotating beating devices, high-pressure airflow systems or laser pest extermination modules, and can accurately operate in farmland, orchards or urban environments. For example, in the agricultural field, the unmanned aerial vehicle can beat crops through a high-speed rotating mechanical arm to knock off or drive away pests; in the warehouse environment, the unmanned aerial vehicle can use high-pressure airflow to remove moths, beetles and other pests in the granary to avoid contamination of food, and compared with chemical control, the mechanical pest extermination unmanned aerial vehicle has the advantages of no pollution, no residue and pests not easy to develop resistance, and is particularly suitable for organic agriculture and ecologically sensitive areas. With the progress of intelligent sensing and automation technology, the mechanical pest extermination unmanned aerial vehicle is expected to become an important tool for green plant protection and promote sustainable agricultural development.

[0003] In some special environments, such as organic farms, ecological protection areas, food processing plants or water sources, chemical pest control methods are strictly limited or prohibited. If there is a lack of effective alternative pest control methods in such scenarios, it may have multiple negative impacts. In agricultural production, pest populations may rapidly multiply, leading to crop yield reduction or even complete loss, directly affecting economic benefits. For example, if chemical pesticides cannot be used in organic tea gardens and physical or biological control measures are insufficient, pests such as tea green leafhoppers are prone to outbreaks, causing a decline in tea quality. Secondly, in the field of public health, such as sensitive places like hospitals and kindergartens, if the disease vectors such as mosquitoes and flies cannot be effectively controlled, it may increase the risk of diseases such as dengue fever and dysentery spreading.
