Abstract

L'invention concerne un système d'aspiration (2) d'une excavatrice aspiratrice (1), comprenant deux turbines (23, 24) disposées l'une à la suite de l'autre, chaque turbine comprenant un carter et des aubes, chaque carter comprenant une entrée centrale et une sortie excentrée, des moyens d'entraînement en rotation des aubes pour la circulation de l'air de l'entrée centrale vers la sortie excentrée en générant une dépression en entrée, un caisson intermédiaire (25) agencé entre les carters de deux turbines, le caisson intermédiaire comprenant une entrée excentrée qui communique avec la sortie excentrée de la turbine amont (23), une sortie centrale qui communique avec l'entrée centrale de la turbine aval (24) et un déflecteur en forme de spirale permettant la circulation de l'air dans ledit caisson intermédiaire de l'entrée excentrée vers la sortie centrale.The invention relates to a suction system (2) for a suction excavator (1), comprising two turbines (23, 24) arranged one after the other, each turbine comprising a housing and vanes, each casing comprising a central inlet and an eccentric outlet, means for rotating the vanes for the circulation of air from the central inlet to the eccentric outlet by generating a vacuum at the inlet, an intermediate casing (25) arranged between the casings of two turbines, the intermediate casing comprising an eccentric inlet which communicates with the eccentric outlet of the upstream turbine (23), a central outlet which communicates with the central inlet of the downstream turbine (24) and a shaped deflector spiral for the circulation of air in said intermediate chamber of the eccentric inlet to the central outlet.
