Abstract

La présente invention concerne une bouche d'aspiration pour une machine d'excavation de tranchée travaillant dans un liquide de forage et comprenant un châssis sur lequel sont montés deux ensembles, rotatifs de coupe à axes parallèles, ladite bouche étant destinée à être montée à l'extrémité inférieure du châssis entre les deux ensembles rotatifs de coupe. La bouche (40) comprend une paroi externe (42) définissant un volume interne (56), une ouverture supérieure (54) raccordable à une conduite d'aspiration et au moins une ouverture inférieure (58) symétrique par rapport au premier plan médian vertical du châssis parallèle aux axes de rotation, et s'étendant selon la direction desdits axes de rotation, par quoi ladite ouverture (58) est sensiblement orthogonale à l'écoulement du liquide de forage entraîné par la rotation desdits ensembles de coupe.
