Drum drive-Ripper 4 is embedded multi-flow turbine 7, for the power which through a flexible pipe 8 pump 9, installed on the underwater module 2, water is pumped. Drum-Ripper 4 is suspended on the bracket 10 mounted on self-propelled truck 3, which is supplied with the electrical cable 11. On the self-propelled cart 3 are also caterpillars turn 12, the additional actuator 13, the remote control system 14. In addition, cart is fixed to the tip of the nozzle 15 hydropolymer pipe 16 with a check valve and shut-off device (not shown).

On the e: dredger 20, and the drum 21 for winding and reeling of the flexible pipe 8 and an electric cable 11, the conveyor 22.

The additional actuator 13 self-propelled truck 3 (Fig.5) consists of an asynchronous motor 23 in waterproof performance is rigidly connected with an adjustable oil pump 24. The oil pump 24 provides power to the motor 25 and right motor 26 left caterpillars. The reversal of the stroke self-propelled truck is provided by the three-position slide valve 27. Equal to the flow rate of the working fluid provides the flow divider 28. Turn caterpillars turn to the right and to the left is provided a two-position spool 29 and 30. Oil system of the actuator is equipped with a device, which is sealed tank 31, a relief valve 32, a filter 33 and a spring-loaded pressure sensor 34.

The oil pump drive is directly proportional to the pressure dependence of the flow (Fig.6), which created the conditions for sustainable operation of the plant by providing the same stiffness characteristics of the drive crawler and hydraulic turbines.

The device operates as follows.

After the descent of the self-propelled truck with 3 underwater module 2 on the bottom, where the surface are alluvial deposits, silt and nodules ores, including the rum on multi-flow turbine 7 of the drum-Ripper 4, which rotates, it loosens silts and placer bottom, throwing away the loosened mass to the tip of the nozzle 15. Caterpillars turn 12 self-propelled truck 3 move along the bottom of the drum Ripper 4 and the tip of the nozzle 15. Opens the shut-off device (valve) on hydropolymer the pipeline 16 and the slurry is sucked into the tip of the nozzle 15 and further through the pipeline 16 due to the pressure difference in the underwater module 2 of the slurry allocated a large fraction (nodules) on dewatering device 17, are dosed in the dosing device 19 and transported by conveyor 22 to the point of accumulation. The remaining liquid phase is accumulated in the accumulating device 18 (sump) and a part of the clarified water is sent to the pump 9. Nodules remain in the underwater module 2, and silts with remaining water is pumped by the dredge, 20 on the craft 1.

Motion control of self-propelled truck 3 is made with boats 1 through the remote control system 14, if the self-propelled trolley is removed from the underwater module 2, Flex 8, gidropony the pipeline 16 and the electric cable 11 are extended, sativas with the drum 21, if self-propelled trolley 3 is approaching the module, Flex 8, gidropony plowed bottom surface of the pump 9 and the actuator 13 self-propelled truck is turned off closes a locking device on hydropolymer the pipeline 16 and the self-propelled carriage 3 along with drum-Ripper 4 rises to an underwater module 2, which changes its presence using the watercraft 1. Then the cycle repeats as long as the quantity of minerals in the craft 1 or underwater module 2 reaches the specified value. Then all lift on the craft or towed to the place of unloading.

Induction motor 23 in a waterproof version, plugged in the underwater module starts.

Adjustable oil pump 24 with spring pressure sensor 34 delivers the working fluid in the discharge line. At the middle position of the three-position slide valve 27, the flow is discharged into the sealed tank 31 through the filter 33. This self-propelled trolley 3 is stationary. When the transfer valve 27 to the left position, the flow from the pump to the flow divider 28. From the flow divider 28, the flow comes to on-off valves 29 and 30. Depending on the position of these spools is determined by the direction of rotation of the motors 25 and 26. They can rotate in one direction, for example clockwise, the valves 29 and 30 are in the left position, self-propelled is away to the left. When switching on-off valve 30 in the right position, and a two-position slide valve 29 is in the left position of the self-propelled carriage will turn to the right.

The movement of self-propelled truck back will be carried out after the transfer of the three-position valve 27 in the right position. When this dip spools 29 and 30 should be in the left position. Turns the truck when driving back are similar to the throwing-off spools 29 and 30.

When changing the mode of operation of the mining machine, associated, for example, with increasing hardness destroy the array, the speed of rotation of the drum Ripper 4 Executive body is reduced, and the load on the motors 25, 26 caterpillars turn 12 increases, which reduces the speed of their rotation (supply self-propelled truck on the array) and growth pressure in the hydraulic system. In this regard, the load on the drum of the Executive body is reduced, and the speed of its rotation is reversed. The increase in pressure in the hydraulic supply causes the displacement of the spring piston pump 24, the spring compression and reduction of the working fluid supply pump 24 through changes in its working volume.

Such education is Yes crawler and hydraulic turbines.
