WING ANGLE ADJUSTABLE UNMANNED AERIAL VEHICLE

WIPO Patent Application WO/2019/080183

A1

A wing angle adjustable unmanned aerial vehicle for spraying plants with a liquid, comprising: a body (1); a pair of fixed wings (2) located on either side of the body (1) and parallel to each other, the end of each of the fixed wings (2) against the body (1) being provided with a wing rotating shaft (21); first rotating wings (3) connected to the wing rotating shafts (21), the first rotating wings (3) being capable of rotating downward around the wing rotating shafts (21); second rotating wings (4) connected to one end of each of the first rotating wings (3) and located on the sides of the first rotating wings (3) against the fixed wings (2), the second rotating wings (4) being maintained parallel to the fixed wings (2); spray guns (5) installed in the first rotating wings (3); and a container (6) installed at the center of gravity of the body (1), the container (6) and the spray guns (5) being directly connected to conduits. The unmanned aerial vehicle can change the rotating angle of the first rotating wings (3) according to the width of vegetation required to be sprayed with a liquid, such that the spray range of the spray guns (5) can correspond to the width of the vegetation required to be sprayed with a liquid, thereby avoiding the vegetation from being repeatedly sprayed for multiple times.
