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...

Examples

Embodiment 1

[0022] see Figure 1-3 , a plant protection unmanned aerial vehicle capable of quantitative spraying, comprising a frame 1 and a power frame 2 fixed above the frame 1, a medicine box 3 is arranged between the frame 1 and the power frame 2, and a medicine box 3 is arranged under the frame 1 Spraying pipe 4 is arranged, and the bottom of spraying pipe 4 has a plurality of spraying heads 41, and spraying pipe 4 is connected with medicine box 3; Described medicine box 3 is provided with storage chamber 32, transfer pipe chamber 34 and quantitative chamber 33 successively, in The top of the storage chamber 32 is provided with a medicine replenishing port 35 for replenishing medicinal liquid and a first pressure stabilizing port 36 for maintaining the air pressure balance in the storage chamber 32, and a port for connecting the storage chamber 32 and the quantitative chamber 33 is provided in the transfer lumen 34. The transfer tube 37, the connection between the transfer tube 37 an...

Embodiment 2

[0027] The difference from Embodiment 1 is that the side of the lifting plate 336 is wrapped with a sealing sleeve 337, and the sealing sleeve 337 is used to ensure the airtightness of the quantitative chamber 33 and the upper and lower sides of the lifting plate 336 during the moving process of the lifting plate 336.
