Title (EN) BUCKET SCOOP WITH ENDLESS SCREW EVACUATOR
(FR) CONTENEUR D'EXCAVATION AVEC VIS SANS FIN D'EVACUATION
Abstract:
(EN) A bucket scoop, for example a drag shovel (1) or a loading shovel, comprises an endless conveyor screw (2) arranged perpendicular to the direction of excavation which conveys the earth excavated by the bucket scoop to an opening (8) in the side walls of the scoop through which the excavated earth is evacuated on one or two sides, said orifice being covered by a cover plate (13).
(FR) Un conteneur d'excavation, par exemple une pelle excavatrice (1) ou un chargeur à benne frontale, comprend une vis sans fin transporteuse (2) agencée transversalement au sens d'excavation et qui transporte la terre excavée par le conteneur d'excavation jusqu'à un orifice (8) ménagé dans les parois latérales du conteneur, de façon à évacuer la terre excavée par un ou deux côtés, l'orifice étant recouvert par une plaque de recouvrement (13).
