FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to mining equipment, namely to a device for development of placer mineral deposits by a dredging method. Dredger comprises a scoop working tool, piles, a stacker and a winch mounted on a pontoon of a dredge with a scoop recess. Bucket-type working tool is made in the form of scraping bucket arranged under pontoon, on rear wall of which knife is made, which is driven by scraper winch, which controls direction of metal cable passing along dredge axis in scoop-slot. On pontoon stern there is a truss hinged to pontoon and hydraulic cylinder and made with possibility of vertical movement. At that, in the scoop slot, on the movable truss and on the stacker, the system of blocks is installed, through which the scraper ladle is connected to the rope and winch for excavation of the echelon dump.
EFFECT: technical result is prevention of soil shedding by fractions of lixiviation waste in zone of bottomhole of dredge.
