Title:
PESTICIDE SPRAYING UNMANNED AERIAL VEHICLE WITH QUICK-INSERTION-TYPE SPRAY PIPE
Document Type and Number:
WIPO Patent Application WO/2021/051427
Kind Code:
A1
Abstract:
Disclosed is a pesticide spraying unmanned aerial vehicle with a quick-insertion-type spray pipe, the unmanned aerial vehicle comprising an unmanned aerial vehicle assembly (1), a pesticide barrel (2), an upper connection pipe assembly (3) and a spray pipe assembly (4). The pesticide barrel (2) is installed in the middle part of the unmanned aerial vehicle assembly (1), the upper connection pipe assembly (3) is installed in the pesticide barrel (2) by means of a booster pump, and the spray pipe assembly (4) is clamped to a lower end of the unmanned aerial vehicle assembly (1). By means of the pesticide spraying unmanned aerial vehicle with the quick-insertion-type spray pipe, the problems occurring when an existing agricultural unmanned aerial vehicle is in use can be solved, these problems including: a pesticide spray pipe being tedious to mount or dismount; pesticide in the pipe being prone to flowing back or leaking when the pesticide spray pipe is dismounted; a bent position of the pesticide spray pipe being prone to blockage due to pesticide precipitation; and it not being possible to adjust the tension degree of the agricultural spray pipe. The pesticide spraying unmanned aerial vehicle with the quick-insertion-type spray pipe can realize quick mounting of the spray pipe of the pesticide spraying unmanned aerial vehicle, and has the advantages of facilitating mounting or dismounting, without pesticide backflow or outflow, without pesticide precipitation in the pipe, and with an adjustable tension degree of the spray pipe.
