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.

The present invention relates to a suction mouth for a trench digging machine working in a drilling fluid and comprising a frame on which are mounted two sets, rotary cutting parallel axes, said mouth being intended to be mounted to the lower end of the frame between the two rotary cutting assemblies. The mouth (40) comprises an outer wall (42) defining an internal volume (56), an upper opening (54) connectable to a suction line and at least one lower opening (58) symmetrical with respect to the first vertical median plane the chassis parallel to the axes of rotation, and extending in the direction of said axes of rotation, whereby said opening (58) is substantially orthogonal to the flow of the drilling liquid driven by the rotation of said cutting assemblies.
