Wing angle-adjustable unmanned aerial vehicle and adjustment method

Abstract

The invention relates to a wing angle-adjustable unmanned aerial vehicle which is used for spraying vegetation with liquid. The wing angle-adjustable unmanned aerial vehicle comprises a fuselage, a pair of fixed wings, a pair of first rotating wings, a pair of second rotating wings, a pair of spraying guns and a container, wherein the fixed wings are positioned on the two sides of the fuselage andare parallel to each other; wing rotating shafts are arranged at the ends, away from the fuselage, of the fixed wings; the first rotating wings are connected with the wing rotating shafts; the firstrotating wings can downwardly rotate around the wing rotating shafts; the second rotating wings are connected with the ends of the first rotating wings and are positioned on one sides away from the fixed wings; the second rotating wings are parallel to the fixed wings; the spraying guns are mounted inside the first rotating wings; the container is mounted at a gravity center of the fuselage; conduits are directly connected between the container and the spraying guns. The wing angle-adjustable unmanned aerial vehicle can change the rotation angles of the first rotating wings according to the width of the vegetation required to be sprayed with the liquid, so that the spraying ranges of the spraying guns can correspond to the width of the vegetation required to be sprayed, and back-and-forthrepeated vegetation spraying is avoided.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with adjustable wing angles and an adjustment method. Background technique [0002] In recent years, with the development of unmanned aerial vehicle technology and the reduction of cost, unmanned aerial vehicles have been widely used in various fields such as military, security, transportation, exploration, surveying and mapping, meteorology, and agriculture. In some civilian fields, drones are generally used to spray pesticides on crops. However, the spraying devices on existing drones are generally fixed and cannot change the spraying range. When spraying some larger fields , it needs to go back and forth several times to complete the work, and when spraying some smaller fields, it is easy to spray the pesticide to the road outside the field, causing a waste of pesticide, and if it is replaced by a rotatable spraying device, A larger spraying ...

In some civilian fields, drones are generally used to spray pesticides on crops. However, the spraying devices on existing drones are generally fixed and cannot change the spraying range. When spraying some larger fields , it needs to go back and forth several times to complete the work, and when spraying some smaller fields, it is easy to spray the pesticide to the road outside the field, causing a waste of pesticide, and if it is replaced by a rotatable spraying device, A larger spraying device is needed, which will increase the burden on the UAV. If the wing is not big enough, it will even be installed outside the wing, which will cause excess wind resistance to the flight of the aircraft and increase the energy consumption of the aircraft.
