Abstract

L'invention concerne une machine de nettoyage de surfaces et à graver à l'aide d'un procédé de sablage sous vide servant au traitement, en particulier au nettoyage de surfaces de pierres naturelles, au nettoyage de carrelages, au nettoyage de façades, à la rénovation d'escaliers, au décapage de revêtements de peinture, à l'enlèvement des graffitis, au nettoyage de modules solaires et à la gravure de différents matériaux tels que la pierre, le béton, le bois, le métal, les matières synthétiques ou le verre. L'invention vise à améliorer les éléments structuraux essentiels des machines et dispositifs actuellement connus qui fonctionnent à l'aide d'un procédé de sablage sous vide, afin de permettre un nettoyage plus efficace de différentes surfaces, d'autres cas d'application et une manipulation plus facile de la machine ou du dispositif. Les modifications et compléments apportés permettent d'augmenter les possibilités d'utilisation de la machine ou du dispositif, de réduire au minimum l'encrassement possible du tuyau d'aspiration, de prolonger la durée de vie de la machine et d'améliorer l'efficacité et les possibilités de commande de la hotte de sablage. À cet effet, des détails techniques et structuraux d'une machine déjà connue sont ajoutés et améliorés, par exemple un dispositif de dosage (3), des compléments apportés à la hotte de sablage (6), des mesures permettant de prolonger la durée de vie de la machine par utilisation de films antigravillons (31).
