Abstract

L'invention concerne un véhicule aérien sans pilote à angle d'ailes réglable qui permet de pulvériser un liquide sur des plantes et qui comprend : un corps (1) ; une paire d'ailes fixes (2) se trouvant de chaque côté du corps (1) et étant parallèles l'une à l'autre, l'extrémité de chacune des ailes fixes (2) contre le corps (1) étant pourvue d'un arbre rotatif d'aile (21) ; des premières ailes rotatives (3) reliées aux arbres rotatifs d'aile (21), les premières ailes rotatives (3) pouvant tourner vers le bas autour des arbres rotatifs d'aile (21) ; des secondes ailes rotatives (4) reliées à une extrémité de chacune des premières ailes rotatives (3) et se trouvant sur les côtés des premières ailes rotatives (3) contre les ailes fixes (2), les secondes ailes rotatives (4) étant maintenues parallèles aux ailes fixes (2) ; des pistolets de pulvérisation (5) installés dans les premières ailes rotatives (3) ; un récipient (6) installé au niveau du centre de gravité du corps (1), le récipient (6) et les pistolets de pulvérisation (5) étant directement reliés à des conduites. Le véhicule aérien sans pilote peut modifier l'angle de rotation des premières ailes rotatives (3) en fonction de la largeur de la végétation sur laquelle un liquide doit être pulvérisé, de telle sorte que la plage de pulvérisation des pistolets de pulvérisation (5) peut correspondre à la largeur de la végétation sur laquelle un liquide doit être pulvérisé, ce qui permet d'éviter de pulvériser le liquide sur la végétation de manière répétée à de multiples reprises.
