Abstract

Inventia se refera la un echipament de draga cu un dispozitiv de transport, cuprinzînd o conducta de transport în care este montat un snec transportor. dispozitivul de transport montat la o nava-draga poate coborî într-o pozitie de lucru, sub nivelul apei, la capatul de aspiratie al conductei transportoare este prevazut un rotor cu cutite. Pentru îmbunatatirea produictivitatii de dragare, snecul transportor este constituit dintr-un arbore tubular si o spira goala la interior. Pe partea superioara a suprafetei spirei snecului sînt prevazute orificii pentru trecerea aerului comprimat, furnizat de un compresor, montat la partea superioara a arborelui tubular.
