Plant protection unmanned aerial vehicle capable of quantitatively spraying

Abstract

The invention discloses a plant protection unmanned aerial vehicle capable of quantitatively spraying. The plant protection unmanned aerial vehicle capable of quantitatively spraying comprises a frameand a power frame fixed above the frame; a pesticide box is arranged between the frame and the power frame; a spraying pipe is arranged under the frame; multiple spraying heads are arranged at the bottom of the spraying pipe; the spraying pipe communicates with the pesticide box; a storage cavity, a transferring pipe cavity and a quantifying cavity are formed in the pesticide box in sequence; a pesticide supplementing port and a first pressure stabilizing port are formed in the top of the storage cavity; a transferring pipe for connecting the storage cavity with the quantifying cavity is arranged in the transferring pipe cavity; and the connecting part of the transferring pipe and the storage cavity is positioned at the bottom of the storage cavity. According to the plant protection unmanned aerial vehicle capable of quantitatively spraying, the internal structure of the pesticide box is skillful; by using a mechanical structure in the quantifying cavity, a pesticide liquid is quantitatively transferred; and by using a pressure sensing structure, the quantity of the transferred pesticide liquid is determined; as the quantitative transferring mode is different from a traditional pumping timing mode, a situation that the quantifying of the whole device is not accurate due to timed pumping after vibrating and mixing excessive gas in the pesticide liquid can be avoided, and therefore, accurate quantification value is guaranteed.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a plant protection unmanned aerial vehicle capable of quantitative spraying. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. [0003] According to the application field, drones can be divided into military and civilian use. For civilian use, drones + industry applications are the real needs of drones. Currently, they are used in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, and observation. Applications in fields such as wild animals, infectious disease monitoring, surveying and mapping, news reports, power inspections, disaster relief, film and television shoo...

Problems solved by technology

[0005] When carrying out large-scale plant protection operations, it is necessary to control the UAV to carry out quantitative spraying in a fixed area, and the current quantitative work mainly depends on the built-in pump for parameter control to complete, and the realization process mainly depends on the liquid throughput in the pipeline or the pump work Timing is achieved, but there are certain problems. For example, when the drone is working, the liquid medicine will oscillate and mix with a large amount of gas. When the pump is pumped, the foam formed by the gas will affect the quantitative accuracy, thus affecting the accurate quantitative spraying.
