COMPLEX FOR EXTRACTING MINERAL RESOURCES FROM OCEAN SHELF ZONE Russian patent published in 2007 - IPC E21C50/00 

FIELD: mining industry, possible use for collecting and sending mineral resources, ferromanganese concretions in particular, to the surface.

SUBSTANCE: complex for extracting mineral resources from ocean shelf zone consists of a surface vessel, endless transporting traction carrier tool with buckets and bottom extraction plant. Traction carrier tool is made in form of conveyor belt, and buckets are made in form of float buckets, positioned with given interval and made with two hollows, one of which is filled with incompressible substance with density less than 1 ton/m³. Traction carrier tool is also provided with hydrostatic intermediate drives positioned on support between branches of conveyor belt, each one of which contains electric motor, leading gear, following drum, and additional conveyor belt with apertures and rods positioned across its whole length, stretching mechanism, pump and support with apertures. By means of branch pipes held on support, pump is connected to closed spaces, formed as a result of tight contact of apertures in support and apertures in additional conveyor belt, mounted in such a way that its rods may interact with leading gear and made with possible friction contact with conveyor belt and possible sliding relatively to support.

EFFECT: extended extraction depth, lower losses of mineral resource during transportation, increased traction force of transporting contour.
