Abstract

Cette Buse (2) pour dispositif de pulvérisation comprenant, à son extrémité distale, un pavillon (5) dont l'ouverture (51) comprend au moins une dent (54, 55, 56). Avantageusement, la présence de dent à l'ouverture de sortie de la buse ou de picots et/ou lames à l'intérieur de la buse tend à perturber l'écoulement du jet d'air. En cas de feuille formant écran au jet d'air, le jet d'air ainsi rendu turbulent, augmente ses chances de dévier la feuille écran et ainsi augmente la pénétration du traitement dans le feuillage.This nozzle (2) for a spraying device comprising, at its distal end, a horn (5), the opening (51) of which comprises at least one tooth (54, 55, 56). Advantageously, the presence of teeth at the outlet opening of the nozzle or of pins and / or blades inside the nozzle tends to disturb the flow of the air jet. In the case of a sheet forming a screen to the air jet, the air jet thus rendered turbulent increases its chances of deflecting the screen sheet and thus increases the penetration of the treatment into the foliage.
