COMPLEX FOR MINING OF FERROMANGANESIAN CONCRETIONS Russian patent published in 2002 - IPC

FIELD: exploration, trial mining of deposits of ferromanganesian concretions located on horizontal or inclined surface of ocean bottom microrelief. SUBSTANCE: complex for mining of ferromanganesian concretions includes submersible apparatus with autonomous system of power supply, and also manipulators with actuating members. Complex is distinguished by the fact that submersible apparatus has accumulating chamber whose upper base accommodates solid matter level position pickup and also two chambers, one of which is filled with water, and the other is filled with granulated lithium hydrite. Chambers are isolated from each other by shutoff member with hydraulic communication between chambers through shutoff member electrically connected with solid matter level position pickup in accumulating chamber. Chamber with granulated lithium hydrite is pneumatically connected through shutoff member with ballast vessel. In addition, submersible apparatus has telescopic manipulators installed for turning through 90 deg in vertical plane. Cantilevered on manipulator ends for rotation are driving reversible shaft with actuating members located thereon. Each actuating member is made in form of receiving chamber rigidly connected with cylindrical crusher and toroidal mill hydraulically connected with each other. Cylindrical crusher is installed on shaft for free rotation. End cantilevered part of shaft is rigidly connected with blade installed for containing the receiving hole and executing rocking motion in free space of internal cavity of toroidal mill. Mill body coming in contact with surface of underlying rocks is reinforced with rubber. EFFECT: improved design and higher efficiency. 2 cl, 6 dwg
