Spray-amount-controllable agricultural unmanned aerial vehicle

Abstract

The invention discloses a spray-amount-controllable agricultural unmanned aerial vehicle. The spray-amount-controllable agricultural unmanned aerial vehicle comprises a machine frame. A controller device is arranged in the center of the machine frame. A main rotor wing is arranged at the top of the controller device. Multiple auxiliary rotor wings are arranged on the outer side of the controller device. A pesticide spraying device is arranged at the bottom of the controller device. A pesticide storage tank is arranged in the pesticide spraying device. Multiple segmented delivery pipes are arranged at the lower end of the pesticide storage tank. Multiple spraying pipes are arranged at the bottom of the pesticide spraying device and are correspondingly connected to the segmented delivery pipes. Supporting wheel bodies are further arranged at the two ends of the bottom of the pesticide spraying device. In this way, the spray amount can be adjusted and controlled according to the climate, the environment and the production cycle of crops when the agricultural unmanned aerial vehicle is used for spraying pesticide, and the purpose of controlling the pesticide spray amount during pesticide spraying can be directly realized by selectively opening the corresponding number of segmented delivery pipes in use.

Description

technical field [0001] The invention relates to the field of robots, in particular to an agricultural unmanned aerial vehicle with controllable spraying amount. Background technique [0002] With the continuous rise of large-scale agriculture, agricultural unmanned helicopters have increasingly appeared in the field of domestic agricultural plant protection operations in recent years. In mountainous areas and hilly areas, unmanned helicopters can do a good job with the advantages of light weight and flexible use. Agricultural drones are suitable for seeding and spraying operations under various environmental conditions. Not only can farmers completely avoid the hazards of personal poisoning, but also the downward pressure airflow formed by the helicopter cantilever will cause swing disturbance to the stems and leaves of crops, thereby forming dynamic spraying . The plant protection effect of this dynamic spraying is far stronger than the static spraying method of walking m...

Problems solved by technology

[0003] However, the traditional agricultural drones have a small liquid storage capacity, and cannot choose a reasonable spraying amount according to the yield and characteristics of crops and climate characteristics, and cannot adjust according to the use requirements, and cannot meet the use under different needs
