Abstract

L'invention concerne un outil de coupe destiné à draguer un sol dur. Cet outil comprend des lames de coupe hélicoïdales pourvues de dents définissant des canaux pour l'acheminement des produits dragués constitués entre lesdites lames et conduisant à une chambre d'aspiration des déblais qui est reliée à un tube d'aspiration.A cutting tool for dredging hard ground is disclosed. This tool comprises helical cutting blades provided with teeth defining channels for the conveyance of the dredged products formed between said blades and leading to a suction chamber for the cuttings which is connected to a suction tube.
