The complex is intended for collection and delivery to the surface of minerals, in particular iron-manganese nodules, can be used in the mining industry.

A device Draga [V.A. Lobanov Reference technique offshore development / Leningrad: Sudostroenie, 1983. 288 pages], including ship security infinitely closed chain with buckets and chain drive. It is able to develop seabed minerals at depths up to 4,000 meters. The disadvantages of this device are low productivity due to inadequate filling of buckets and as a consequence low quality testing of bottom sections of the deposits, the entanglement of branches of chain.

A device of the underwater hydraulic mining complex [Patent No. 2203421 of the Russian Federation. Installation for the extraction of minerals from the bottom of the water area // of the Invention. 2003. No. 12], including surface craft with the necessary devices for supporting and operating staff and supply and management of complex, gidropony pipeline, bottom machine on tracks with drum Executive body. The device works in the following way: drum Executive body carries out the process of separation of the nodules from the bottom surface and drop them to the entrance of the oval with the La to mix with water and feed in the form of a slurry in a flexible gidropony pipeline with subsequent unloading tanks in boats. However, this device has drawbacks: the requirement of higher capacity crawler drive due to low efficiency, difficulty in control of the bottom mechanism associated with an increased turbidity of the environment during operation of the track chain, the limited performance of the system due to the need to reduce the diameter of the pipeline when working at great depths, the possibility of tastybaby pipeline, the overall complexity of the hydraulic mining of the device as a whole.

It is also known device [Device for the extraction of nodules from the sea shelf. Application No. 95112283]closest to the declared object and which is adopted for the prototype. The device consists of surface vessels with installed equipment to ensure operation of the device, the transporting path with buckets, tow rope, seabed mining device in the form of a half attached to the sled. The device works in the following way: by means of the towing rope surface craft passes forward movement of seabed mining unit, the transporting path with buckets passes in the cavity half, where the drawing of the extracted minerals and subsequent unloading at the craft. This device has drawbacks: shallow depth development, Oteri mineral during transportation due to free exaggeratedly branches of the transport path, low traction transporting path.

The technical result is to eliminate these drawbacks, namely: the increase of mining depth, the loss of minerals during transportation, improving traction transporting path (conveyor belt with buckets).

The technical result is achieved by the fact that the complex development of mineral resources of the shelf zone of the World Ocean, consisting of surface vessels transporting endless traction-carrying body with buckets of seabed mining installation according to the invention it traction-bearing body in the form of a conveyor belt and buckets made in the form of buckets, floats, located at a specified interval and performed with two cavities, one of which is filled with an incompressible substance with a density less than 1 t/m3and have posted on the rod between the branches of the conveyor belt hydrostatic intermediate drives, each of which contains a motor, pinion gear, a driven drum, and additional conveyor belt with holes and pins, spaced along the length, the tension mechanism, the pump and support with holes, with a system of nozzles mounted on the support, a pump associated with the closed volume formed in the pressing holes which support and additional holes in the conveyor belt, installed with the possibility of interaction of its pins with the pinion and is made with the possibility of frictional contact with the conveyor belt and slide relative to the support.

The complex shown in the drawings, where figure 1 shows the General scheme of the complex; figure 2 presents hydrostatic intermediate drive (node I in figure 1);in figure 3 - section A-a in figure 2.

Presents the complex development of mineral resources of the shelf zone of the World Ocean consists of the supply vessel 1, the transporting trailer carrying body, which contains a conveyor belt 2, which with the interval specified performance setup attached buckets-3 floats. They consist of buckets having enhanced by the interaction of the bucket with a ground cutting edge with the cutter. One cargo 4 cavity of the bucket is designed for direct intake of the mineral, and the other cavity 5 is filled with an incompressible substance with a density less than 1 t/m3such as polystyrene with a density of 15 kg/m3. When this is achieved zero buoyancy conveyor belt with buckets. The bucket floats 3 are located on the tape at intervals determined by the specified capacity.

Complex development of mineral resources of the shelf zone on ocean contains hydrostatic who tick the actuator 6 in transporting endless traction-bearing organ of the complex. Hydrostatic intermediate actuator placed between the branches of the conveyor belt 2 and are mounted on the rod 7 made in the form of the pipe string. The number of intermediate drives depends on the depth of development. With increasing depth increases and the number of intermediate drives. Each of them contains the motor 8, the gear 9, the pump 10, the system of pipes 11, attached to the support 12 with holes to create a vacuum in the system, the tension mechanism 13. The tension mechanism using a spring moves the clutch drum 14 and thereby creates additional tension conveyor belt 15 of the intermediate drive required for its normal operation. Thus the plane of the contact support 12 and 15 additional conveyor belts are made with high purity, which reduces friction by contact and allows you to slide an extra 15 tape along the support 12. Additional 15 conveyor belt intermediate drive made with the pins 16 and the through holes 17. Thanks pinion 18 and the pin 16 moves additional 15 conveyor belt.

As seabed mining installation, the walking machine. The design of a walking machine with moving working head 19 consists of a welded farm 20 attached to the monorail, the ends of the farm together with a monorail curved back is H. The monorail is used as the traction and the reference node for the undercarriage. To it by using elastic elements suspended water pump. With enough weight, he performs in addition to mining functions the function of a counterweight to ensure traffic best diving in the mechanism. Ripper 21 is made in the form of a flat spiral. During operation, it rotates around a vertical axis, which increases the loosening of the developed soil and increases suction capacity of the soil pump. Using curving of the pipeline 22 and conical thickener pump 23 is connected with the hopper 24 from which it draws enriched nodules. Conical thickener 23 performs the role of primary refinery produced nodules, in addition, it improves the performance of the Elevator, since in this case the buckets scoop more condensed mass. The hopper 24 is made in the form of a metal box. In the center of the bin is the end of the drum. The axis of the drum is spring-loaded, it is connected with disturbances of the sea and due to the compression of the springs does not occur the bottom of the unit from the bottom during adverse conditions. Farm 20 is suspended from two support tables 25 so that the ends thereof with curved sections form the console fixed length.

We offer complex for development of mineral resources of the shelf zone of the World Ocean which operate as follows. The working cylinder 19 moves in the console section of the walking machine and is embedded in the ground. The soil extracted minerals (such as iron-manganese concretions) is loosened spiral Ripper 21 and absorbed the soil pump, after which the slurry pipeline 22 through conical thickener enriched mixture is fed into the hopper 24. From the hopper by means transporting an endless traction-carrying body with buckets is drawing and further movement to the vessel enriched mixture.

Trailer bearing body is driven hydrostatic intermediate actuators 6. Hydrostatic intermediate drive works as follows: from the electric motor 8 is fed by the pump 10, which through a system of pipes 11 removes water from the closed volume formed in the pressing holes in the support 12 hydrostatic intermediate drive and holes 17 located in the working lining additional 15 conveyor belt intermediate the actuator to the opposite side of the working branch of the conveyor belt 2 devices. Due to the presence of these cavities is pressed against a working branch of the conveyor belt 2 infinite trailer carrying body with buckets to additional conveyor belt 15 of the intermediate actuator 6. Leading gear 18 is engaged with the pins 16 more the tion 15 of the conveyor belt and due to the high frictional contact between the secondary intermediate tape drive and the working branch of the conveyor belt 2 transport trailer carrying body moves conveyor belt 2 with 3 buckets.

Raised to the vessel 1 by means transporting trailer carrying body enriched mixture is first stored in the holds, and then using barges transported to shore for further processing.

Thus, with the proposed set of possible mining at great depths, loss of minerals during transportation, improving traction transporting path.
