The disadvantages of this complex are limited the icenii performance conditions capture mineral mining unit, the complexity and unreliability of the intermediate drive of the transport device belt-bucket type because of the need to constantly maintain the vacuum between the towing carrier and traction tape using a special pump, unwise use as a traction unit of the transport device rubberized conveyor belt for the following reasons: because of its high cost and the possibility of rapid deterioration in the placement of the tape in sea water, the impossibility of maintaining a given orientation of belt-bucket traction-carrying body in the presence of underwater currents, which can result in twisting of the traction-bearing body and its failure. When performing buckets with zero buoyancy, their dimensions must inevitably be increased, which will lead to complication posted on mining unit of node overload of extracted mineral.

The technical result of the invention is to improve the performance of complex, simplified design, reduced material consumption, energy consumption and cost, increased reliability of operation of the complex.

Complex for the development of ferromanganese nodules from the shelf zone of the world ocean contains basic vessel 1 with receiver 2 for mineral, a flexible pressure pipe 3, which one of its end fixed on the base Board 1, and the other is mine unit 4 can move along the bottom 5 of the shelf zone. Mine unit 4 consists of rolling a gripping device in the form supplied by the blades 6 of the drum 7. The drum 7 mounted on kinematically associated with the actuator 8 axis 9. The blade 6 is placed with a minimum clearance of 10 relative to the inner surface of the casing 11 has a cylindrical shape. The surface of the casing 11 perforated holes 12, the diameter of which is accepted is less than the minimum lateral dimension of the extracted nodules. The axle 9 is installed with the possibility of rotation in the Central part of the side walls 13 of the casing 11. The casing 11 in its lower part provided with a neck 14 of a rectangular shape in plan with the ability to accommodate blades 6 and their implementation in thickness 15 fossil. The blade 6 is made with deflections that when the blades 6 in the lower part of the casing is oriented in the direction opposite to the direction 16 move production unit 4. The distance between the villas of the blades 6 is made smaller than the minimal is tion of the transverse size of the extracted nodule.

The cutout 14 in the casing 11 is made in such a way that its edge is placed over the useful thickness of 15 fossil. The casing 11 through the discharge pipe 17 tapering cross-section is connected with the suction inlet 18 of the soil of the pump 19. Water pump 19 is mounted on the transverse beams 20 ski-21 from the side of the casing 11 opposite to the direction 16 move production unit 4. The discharge nozzle 22 of an underground pump 19 is connected with a perforated area 23 of the pipeline attached to the casing 11 and is placed over it, with the possibility of connection of the perforated area 23 of the pipeline with a flexible pressure pipe 3. A flexible pressure pipe 3 is oriented in a plane coaxial with the discharge pipe 22 ground pump 19 at a right angle to the axis 9 and the longitudinal axis of symmetry of the casing 11. Axis ground pump 19 may be located along the longitudinal axis of symmetry of the casing 11 (2 and 3) or perpendicular to it (figure 4).

Mine unit 4 balanced in the transverse direction. Skis 21 fixed on two sides, the side walls 13 of the casing 11 and is made V-shaped in cross section. A flexible pressure pipe 3 is made from a combination of tough straight pipes 24 and flexible inserts 25 of elastic material with the connection of adjacent tubes 24 are placed around the perimeter of each tube 24 cu is glossanime circuits 26, perceiving tensile forces.

Flex 3 can be made zero buoyancy due to the attachment thereto of floats or other items with low density (not shown). On the flexible pipe 3 fixed power cable (not shown)connecting the base vessel 1 with motor drives the drum 7 and the underground pump 19.

The complex operates as follows. When moving the base of the vessel 1 through a flexible pipe 3 tractive force is transferred to the unit 4, which at its ski-21 is moved along the bottom 5 of the shelf zone. When the actuator 8 of the drum 7 mine unit 4 and moving it in the direction 16 of the forked blades 6 due to the interaction of their outer edges with a thickness of 15 mineral, accompanied by the introduction into it of the blades 6 under the action of the weight of the unit 4, nodules picked up by the blades 6 and move with them during the rotation of the drum 7 counterclockwise (figure 2) up inside the casing 11. Due to their V-shaped cross-section of the ski-21 provides for the necessary depth of penetration of the blades 6 in column 15 of the mineral and its capture by the blades 6 due to the fact that moving production unit 4 skis 21 are embedded in the thickness of 15 mineral that contributes to the introduction into it of the blades 6 and the seizure of useful iscope the th. During the rotation of the drum 7 due to the forked shape of the blades 6 and wrap posted nodules colliding streams of water concretions are exempt from a significant portion of bottom sludge and low grade particles through the holes 12 in the cover 11 removed beyond. This process intensifies due to turbulence in flows inside the casing 11, created a rotating drum 7 with 6 blades, due to the overload of nodules with one blade 6 to the other during rotation of the drum 7 when the blade 6 are in the area before overload nodules in the discharge pipe 17, and also due to the translational motion of the mining unit 4. During rotation of the drum 7 with a lowering of the blades 6 down-enriched mass of nodules rolls off of the blades 6 and continuously reloaded into the discharge pipe 17, which is due to the vacuum generated groundwater pump 19, enters its suction nozzle 18. Next, the slurry through the discharge pipe 22 ground pump 19 under pressure is directed into the perforated portion 23 of the pipeline in which there is an additional exemption slurry from the slurry particles and the decrease of water content in the slurry to the optimum value corresponding to the minimum energy consumption during transportation. Further enriched slurry with reduced to about the optimum level of water content is delivered in a flexible pressure pipe 3 and is transported to the receiving device 2 to the base of the vessel 1. Longitudinal and lateral stability of the extracted unit 4 is provided with ski-21, which communicate with the ground 5.

The execution of the capture mechanism of the mineral in the form attached to the rotating of the actuator 8 reel 7 forked blades 6 provides continuous capture and enrichment of minerals and continuous flow in the discharge pipe 17 from which the soil pump 19 slurry is fed into the discharge line 3. This not only increases system performance, but also significantly simplifies the design of the mining unit 4. This provides a dual pre-enrichment of minerals: in the beginning inside the casing 11, and then by passing the slurry through a perforated area 23 of the pipeline. Ensuring capture of minerals by means of rotating of the actuator 8 of the drum 7 with 6 blades helps to reduce resistance to movement of the mining unit 4 and to reduce the total energy of the complex. Thus due to the displacement of the center of gravity of the mining unit 4 in the direction of the axis 9, opposite to the direction 16 of its movement, the resistance to movement of the mining unit 4 and the intensity of the complex is additionally reduced. The moving unit 4 using as a traction unit for moving mining AG is Agata 4 flexible discharge pipe 3, which does not only transport, but also serves as a traction body, additionally simplifies and cheapens the construction of the complex and increases the reliability of his work.

Thus, features of the invention provide improved performance of complex, simplified design, reduced material consumption, energy consumption and cost, increase reliability of operation.
