  • the seal 990 defines the air-flow path 996 across a forward portion of the gutter broom apparatus 920 between the mounting plate 932 and the roof portion 972 of the shroud 970.
  • the air-flow path has an egress 996b in air delivery relation with respect to the air outlet 976 of the gutter broom apparatus 920, and an air ingress 996a in air-receiving relation with respect to the bristle presenting opening 977.
  • the seal 990 comprises an inner portion 992 that extends along the air-flow path 996 and a peripheral portion 994 disposed adjacent the periphery of the mounting plate 932 clockwise from the air ingress 996a to the air egress 996b.
  • the air outlet 976 of the gutter broom apparatus 920 has been located to be ad j acent to the air egress 996b.
  • the air-flow precluding member is substantially solid, thereby precluding air flow from being directed upwardly into the interior of the air-flow precluding member, as is possible in the other embodiments, thereby keeping the air flow that is under the air-flow precluding member close to the surface being cleaned.
  • the present invention provides a high efficiency dust controlling gutter broom apparatus that precludes a thin layer of dirt, dust or other fine particulate matter from remaining on a surface being cleaned after the gutter broom passes over, that captures virtually all of the airborne dust or other fine particulate matter that is created by gutter brooms during use, that reduces the amount of air that needs to be applied to gutter broom shrouds during use, and that is inexpensive, all of which f eatures are unknown in the prior art.

Abstract

L'invention concerne un appareil balai de caniveau très efficace, qui permet de lutter contre les poussières, devant être utilisé sur un véhicule de nettoyage de surface et qui comporte un bras de fixation et un balai de caniveau pourvu d'une structure de montage et de poils suspendus à la structure de montage. Le balai de caniveau est monté par l'intermédiaire de la structure de montage en une relation de support sur le bras de fixation afin de pouvoir tourner autour d'un axe de balai de caniveau. Un moteur de balai de caniveau est relié de manière fonctionnelle et en une relation de commande au balai de caniveau afin de le faire tourner autour de l'axe de balai de caniveau. Une enveloppe est composée d'une partie toit et d'une partie mur qui est suspendue à la partie toit. L'enveloppe soutient le bras de fixation de manière à ce que la partie toit recouvre au moins une partie arrière de la structure de montage du balai de caniveau et que la partie mur recouvre au moins une partie arrière des poils du balai de caniveau. Un élément empêchant l'écoulement de l'air est fixé sur le balai de caniveau de manière à pouvoir tourner avec celui-ci, afin d'entraver de manière significative la circulation de l'air dans le balai de caniveau.
