Groundsamine device relates to the mining of polymetallic nodules from the bottom of the World ocean and is part of the relevant marine complex.

Known groundsamine device containing slurry line with mixer tap, hydraulically communicated with underwater vessel (Flywheel BS, Shalygin A.V. Creating hydraulic actuators for underwater mining machinery / Mining machinery and automation. - M.: "New technologies", 2004, No. 2, P.9-10)in the cavity of which there is an air of atmospheric pressure, the working body in the composition of the oil of the hydraulic motor and Ripper, self-propelled cart, is connected by a bracket with a working body, oil-pumping station with a pump and a water motor, water motor powered directly from the waters, and the output of water from it communicated with a mixer. Power actuators and control process protozanova is carried out remotely, for example from the underwater vessel. Rippers mounted on the drum with a horizontal axis of rotation, a drum connected to the shaft of the hydraulic motor of the working body.

The disadvantage is the lack of bandwidth of the mixer performance drum Ripper, and remote control operate without control of work performed. These factors reduce the performance grantsa REGO device. In addition, similar to pollute the waters.

Known volumetric hydraulic motor (patent RU №2295062, publ. 10.03.2007,), in which the entrance and exit of the working fluid conducted through the openings in the casing, plungers presented in the form of a swinging spring-loaded dampers. As the working fluid can be used viscous liquid or water.

Known groundsamine device in the marine complex for production on the shelf or in deep-water areas of the World ocean nodules, cortical formations or other ground soil, representing polymetallic ore (patent RU №2112139, publ. 27.05.98), which includes slurry line with mixer tap, hydraulically communicated with underwater vessel, the cavity of which there is an air of atmospheric pressure, the working body in the composition of the volume of the hydraulic motor housing, shaft, pressure and drain channels, Ripper and casing, self-propelled cart, is connected by a bracket with a casing, oil-pumping station with a pump and a water motor, water motor oil station powered directly from the waters, and the output of water from it communicated with underwater vessel.

Features of the second analog:

the hydraulic working body has not horizontal rotating shaft and the rotating body with rippers, making a circular motion in a vertical pleskot is. The mixer has a shape of a trapezoid and rectangular inlet opening in a vertical plane, the longest side parallel to the bottom area. Hydraulic motor with rippers placed in an enclosure designed for the protection of water from pollution by products of loosening. Rippers offers products loosening to the inlet of the mixer, and the existing in the slurry line pull flow, caused by the difference of the ordinates of the location of the mixer and the underwater vessel, pulls these products in the mixer and transports them to the underwater vessel type process called "hydropower loose". From this vessel the slurry is pumped mud pump on the barge (floating).

The disadvantages is that from the side of the mixer casing does not cover the actuator, and the products loosening dissipate as past of the mixer and through the lower slots on three sides of the casing, polluting the waters. Also, since the products of loosening not fall in full at the inlet of the mixer and there is no possibility to monitor the status of the seabed and process protozanova, the performance of the prototype reduced.

Known groundsamine device (patent RU 2459083, publ. 20.08.2012)adopted for the prototype, which includes slurry line with a conical mixer, having an input cross-section with a diameter Dcin the horizon the through plane, working body with a vertically mounted hydraulic motor, shaft, rippers and a cylindrical casing, a self-propelled cart, is connected by a bracket with a cylindrical casing. Moreover, the slurry line is hydraulically communicated with underwater vessel, the cavity of which there is an air of atmospheric pressure, and a cylindrical casing connected at one end with the slurry line and the other with a conical mixer.

The disadvantage of the prototype is suboptimal performance of protozanova because of the time spent on such unproductive operations, as the raising of the working body, moving it to a new position, lowering of the body, a new lifting, moving, lowering, etc. and only the work of this body in the lowered condition provides protosolar (in one position).

The technical result of the invention is to improve the performance of the suction head; it is at the expense of achieving continuity is mined in a given area of the bottom waters.

The technical result is achieved by the fact that in gruntsgabalam device for underwater mining of ferromanganese nodules maximum size δ, which includes slurry line with a conical mixer, having an input cross-section with a diameter Dcin the horizontal plane and hydraulically communicated with p is wodnym vessel, in the cavity of which there is an air of atmospheric pressure, the working body with a vertically mounted hydraulic motor, shaft, rippers and with a cylindrical casing connected at one end with the slurry line and the other with a conical mixer, as well as self-propelled cart, is connected by a bracket with a cylindrical casing, rippers working body in the form of cutters, which are mounted on additionally mounted on the shaft of the hydraulic motor conical casing length lkthe maximum upper diameter Dkand minimum bottom diameter dkwhile the conical housing with cutters mounted below the horizontal input section of the mixer, subject to the inequality Dk<Dcand on the lateral surface of the conical body has a through hole with a minimum cross-sectional dimension of lo≥δ, in addition, the bracket is connected with a self-propelled trolley by means of a rotary cylinder with a vertical axis of rotation.

This device allows, once introducing the working body to a predetermined depth within the lki.e. having a front feed of the tool on an array of deposits, and rotating it in a horizontal plane at one side of the rotary cylinder at the maximum possible angle φ with the subsequent reversing truck (or before which they move) step h≤D kand reversive the direction of swing of the working body in the other direction at the same angle φ with the subsequent reversing truck step h≤Dkand so on, to achieve continuity is mined in a given area of the bottom waters, i.e. to improve the performance of protozanova.

The invention is illustrated by drawings, where figure 1 shows a set of equipment for underwater development of deposits on the shelf with the claimed gruntsgabalam device, figure 2 is a longitudinal section of the suction head; it is in figure 3 is given a top view of groundsamine device with a self-propelled truck and given the trajectory of the working body in the horizontal plane.

Conical mixer 15 has an input section with a diameter Dcsituated in the horizontal plane 21. The slurry line 12 is hydraulically communicated with underwater vessel 3 in the cavity which has an atmospheric air pressure pa. The hydraulic motor 16 mounted vertically. The casing 22 has the shape of a cylinder and connected by one end with the slurry line 12, the other with a mixer 15. Self-propelled trolley 5 is connected by the bracket 11 with a cylindrical casing 22 of the working body 10. In the underwater vessel 3 with the electrical and pumping equipment for pumping slurry through the upper slurry line 2 in the craft 1. Self-propelled cart with 5 working body 10 are connected by a cable 4 to the gateway of the underwater vessel 3 to rise to service. Slurry lines 2 and 12 have positive buoyancy. Cabin 7 is in communication with the air atmosphere of the channels 14. The annular channel 23 brings the eat S=π4(DKaboutW2-DD2)radial size of 0.5(Dleather-DD)≥δ skips nodules specified size S. the Cabin 7 is equipped with a oil station 6 with a drive water engine running on the differential head H=Z1-Z2. Evacuation of spent water from a water engine oil station 6 is on channel 13, which is connected to an underwater vessel 3. The largest cross-section of the trench formed by the movement of the crown in the plane 21 that corresponds to the shape of a truncated cone with dimensions 4, lkDkdk.

The hydraulic motor 16 of the working body 10 made of a type and can be sliding, for example, patent RU No. 2295062. It can be water using differential H=Z1-Z2and oil powered from the pumping station 6. This allows a high driving torque on a shaft 18 with a low differential head H by increasing the axial length of the hydraulic motor 16 when the annular flow channel 23, which must pass nodules maximum size δ. When this exhaust in the engine 16, water is diverted to the underwater vessel 3 through the channel 13. The water engine milostan the AI 6 can also be made according to the patent RU No. 2295062. The return water via a flow path of the slurry line 12 (as both analogues) are unreliable, because it is filled with nodules and silt slurry line can be stopped for technical reasons, and the oil station 6 at this time should work for moving the trolley 5 and manipulation of the working body 10. In the presence of channel type 13 made as a prototype ensures the reliability of functioning of the inventive suction head; it.

While the cutters 20 slip nodules and disrupt cortical education. Next, open the valve on the slurry line 12 (located in the underwater vessel 3; not shown) creates a transport stream water (thirst), directed upwards through the mixer 15 with the input section ofSC =π4(DC2-Dk2), annular channel 23 sectionS=π4(DKaboutW2-DD2)and the cavity of the slurry line 12 with its end in a submerged vessel 3, in which there is an air of atmospheric pressure pa. Created by the pull of the thread acquires nodules and particles of bottom rocks and on the principle of "hydraulic lift" transports them into the specified container.

The destruction of the bottom of the rocks occurs under the hood, which is the casing 22 with a mixer 15, and the suction of the water with solid admixtures happens annular space between the mixer 15 and the crown 19 and through the window 17 in the crown, the transverse size of laboutwhich skips nodules maximum size δ. Dispersion roiled the surface of the bottom of the specified cap beyond mixer no - this keeps the positive environmental effect of the prototype.

After the introduction of the crown 19 in the array to a predetermined depth perform horizontal flow of the working body 10 by the angle φ rotatable gidrol Ingram 8 - is protosolar to the point B from the trench having a cross-sectional shape in the form of a trapezoid cross-section STP=0,5(Dk+dk)·lk. Without turning off the hydraulic motor 16, operate self-propelled truck 5 reversing step h≤Dk. Then include a cross feed of the working body 10 with the rotary cylinder 8 in reverse - is protosolar from point C on the angle φ, then step back truck 5 (or step), and so on. Continuous movement of the working body 10 under load as described trajectory provides the exception of non-productive operations of the prototype, hence the performance of the suction head; it grew.
