COMPLEX FOR MINING AND PROCESSING OF SOLID MINERALS Russian patent published in 2012 - IPC E21C50/02 

FIELD: mining.

SUBSTANCE: complex comprises a floating facility, the following components installed on it: a receiving accessory, a lifting single-drum and double-drum scraper hoists, diverting units, head and tail traction ropes, a perforated vessel of rectangular cross section with cutting edges, bottom anchors with buoys. At the same time the head rope is kinematically linked with a longitudinal traction rod and ropes hingedly joined with levers of cutting planes as capable of their rotation to close a vessel base in the form of a spatial frame of square cross section with their closure by side edges, forming faces of a rectangular pyramid aligned with the top outside along the longitudinal axis of the device, the cutting plane of which is arranged in the form of isosceless triangles adjoining hingedly with their bases to bases of the specified frame bases, inside of which there is a screening drum of cylindrical shape, which rests with its circular bands with flanges onto rollers fixed in the inner corners of the frame faces, the cylindrical surface of the screening drum screening is formed by longitudinal bars installed along the cylinder generatrix and fixed on circular bands to form longitudinal slots between them, the cylindrical surface of the screening drum is embraced with ropes fixed on the drum and wound along the helical line, at one side in the right direction, and at the other side - in the left direction, and coming off the drum along the tangent to the cylinder circumference, the device is equipped with a polyspast with a fixed shell of units fixed on the frame, and a movable shell capable of its displacement along the frame face, and the angle of rotation of the screening drum by 360 degrees is provided with the length of the rod travel with the traction rope.

EFFECT: higher efficiency and environmental capability of works in mining of solid minerals from a sea bottom.
