Abstract

L'invention concerne un dispositif automoteur de traitement de sol et une buse d'aspiration (1000). Le dispositif automoteur de traitement de sol comprend un corps de dispositif principal et une buse d'aspiration (1000) reliée à ce dernier. Une entrée d'aspiration (100) est formée au fond de la buse d'aspiration. Dans un processus de fonctionnement, la buse d'aspiration (1000) est conçue pour se déplacer dans une direction vers l'avant (A). Une bande d'étanchéité avant (1003) est disposée sur un côté avant de l'entrée d'aspiration (100) et comprend une extrémité fixe (10031) et une extrémité libre (10032) s'étendant jusqu'à une surface de travail (B). La bande d'étanchéité avant (1003) est flexible et est conçue pour s'écarter de la direction avant de façon à former, devant une saillie de l'extrémité libre (10032) sur la surface de travail (B), une saillie de l'extrémité fixe (10031) sur la surface de travail (B). L'étanchéité environnante à la périphérie de l'entrée d'aspiration (100) de la buse d'aspiration (1000) améliore l'aspiration sous vide de l'entrée d'aspiration (100), ce qui permet d'augmenter la capacité d'élimination de poussière du dispositif automoteur de traitement de sol. La direction de configuration, la forme et le matériau de la bande d'étanchéité avant (1003) assurent une aspiration efficace de grosses particules de poussière, maintiennent un degré élevé de résistance au vide de l'entrée d'aspiration (100) et offrent une efficacité d'élimination de poussière élevée.
