Description

The utility model relates to mining, in particular to devices for underwater mining. The device can be used in the mining industry.

A known installation for the extraction of ferromanganese nodules (Timofeev I.P. Walking machines for the development of the resources of the seabed / Leningrad: Leningrad University Publishing House, 1987. - 176 p. 9-11), equipped with a surface floating craft, a transporting body, a bottom mining collection device with a hopper for filling buckets fixed on a pulling rope. The mining device is installed on a skid, equipped in the front part with a ripper knife, has a bottom in the form of a screening grate, it moves with the help of a rope. The movement of the mining device along the bottom and the scoops on the rope are controlled from the surface craft.

The disadvantages of this installation are that the design of the ripper knife does not provide preliminary destruction of strong cobalt-manganese crusts.

Known installation for the extraction of ferromanganese nodules from the bottom of the seas (RF patent No. 2289696, publ. 20.12.2006), containing a carrier vessel on which the controls of the installation are located, a bottom unit for collecting ferromanganese nodules, mounted on a frame, a slurry pumping unit with pumps, a device for lifting ferromanganese nodules to the ocean surface, and the bottom unit for collecting ferromanganese nodules is made in the form of a tracked chassis driven by a conveyor and a unit for pumping FMN slurry with multi-section piston pumps for supplying slurry from the ocean floor to the mesh containers of the conveyor by means of a loading and transport pipe.

The disadvantage of this installation is the design of the bottom unit for collecting ferromanganese nodules, the undercarriage of which is made in the form of a caterpillar chassis, which does not provide the ability to move along the slopes of seamounts (guyots), on which cobalt-manganese crusts lie.

A device for selective selection and preliminary enrichment of ferromanganese nodules is known (RF patent No. 2375578, publ. 10.12.2009), including a surface floating craft, a transporting body, a bottom mining device in the form of a drum with longitudinal grooves on the outer surface.

The disadvantages of this device are that the executive body of the bottom device, made in the form of a drum with longitudinal grooves, does not allow capturing cobalt-manganese crusts, which require preliminary separation from the bedrock surface of the slopes of seamounts and depressions and the impossibility of movement along the intricately crossed surface of the seabed.

Known bottom mining device for collecting ferromanganese nodules from the seabed (utility model patent RF No. 178978, publ. 04/24/2018), including a cable-rope, a cone-shaped receiving hopper, rigidly connected to a rack located inside the central pivot, equipped with a toothed rim that meshes with two drive gears mounted on the rack, L-shaped levers with vacuum grippers.

The disadvantage of this device is the impossibility of reliable capture and retention by vacuum grippers of ferromanganese crusts without their prior destruction.

It is known a bottom mining device for collecting ferromanganese nodules from the bottom of the seas (patent for a useful model of the Russian Federation No. 186415, publ. 01.21.2019), taken as a prototype, including a receiving hopper rigidly connected to the rack, a central trunnion with a swing mechanism, hinge-link mechanisms moving the receiving hopper with hydraulic cylinders, vacuum grippers.

The disadvantage of this mining device is that vacuum grippers do not provide the possibility of preliminary destruction of ferromanganese crusts that form covers on the hard rocks of the slopes of seamounts, and, consequently, their selection and capture.

The technical result is the creation of a structure that provides the possibility of preliminary destruction and separation of cobalt-manganese crusts from the bedding rock, their selection and reliable capture in conditions of movement along a complexly intersected surface of the seabed.

The technical result is achieved by the fact that the grippers are made in the form of grabs with jaws and hydraulic cylinders for their movement, pivotally fixed on a cylindrical body, made with an eyelet for connection with the free ends of the hinge-lever mechanisms, inside which a shock lance and a piston-striker are located coaxially, forming with a cylindrical camera body forward and backward.

The device 1 for collecting cobalt-manganese crusts from the bottom of the seas (Fig. 1) includes a receiving hopper 2, rigidly connected to the rack 3, located inside the central pivot 4, equipped with a turning mechanism 5. The upper part of the central pivot 4 is connected to the cable-cable 6, and the lower - is pivotally connected to the hinge-link mechanisms 7, equipped with hydraulic cylinders 8 and grippers 9, made in the form of grabs 10 (Fig. 1, 2).

The grab 10 (Fig. 2) is equipped with jaws 11 and hydraulic cylinders 8 for their movement, secured by cords 12 on a cylindrical body 13, made with an eyelet 14, for connecting the grab 10 with a hinge 12 with the free ends 15 of the hinge-lever mechanisms 7. Inside the cylindrical body 13 are located coaxially the impact lance 16 and the piston-firing pin 17, forming a forward stroke chamber 18 and a reverse stroke chamber 19 with the cylindrical body 13.

The proposed device for collecting ferromanganese crusts from the bottom of the seas works as follows.

The device 1 from the floating craft 22 (Fig. 3) with the help of a cable-rope 6, is lowered to the surface of occurrence of cobalt-manganese crusts 20 of the seabed 21. Since the conditions of occurrence of cobalt-manganese crusts are characterized by the dissection of the surface of the seabed (cobalt-manganese crusts form covers on the surfaces and slopes of underwater hills , mountains or depressions), then after the receiving hopper 2 descends to the bedding surface, it is necessary to ensure that its stable position is fixed on an uneven surface. With the help of hydraulic cylinders 8 of the lever mechanisms 7 located on the rear side 23 of the receiving hopper 2, the grabs 10 with open jaws 11 (Figs. 1, 2) fixed on them by the hinges 12 are lowered until they come into contact with the bedding surface. The grabs 10 are powered by a hydraulic distribution system (not shown) of a device 1 for collecting cobalt manganese crusts 20 from the seabed 21.

The hydraulic cylinders 8 of the lever mechanisms 7 create a sufficient force of pressing the jaws 11 to the surface of the seabed 21, thereby ensuring reliable fixation of the receiving hopper 2 of the device on the surface of occurrence of cobalt-manganese crusts 20.

Further, the hydraulic cylinders 8 of the lever mechanisms 7 located on the front side 25 of the receiving hopper 2 lower the grabs 10 fixed on them by the hinges 12 onto the surface of the occurrence of ferromanganese crusts (Fig. 2). The hydraulic distribution system of device 1 (not shown in the drawing) alternately supplies pressure to the forward stroke chamber 18 and reverse stroke 19 of the cylindrical body 13, providing a reciprocating movement of the piston - striker 17, striking the shock lance 16 and, thus, on the surface cobalt-manganese crusts 20, which ensures the destruction of strong cobalt-manganese crusts and their separation from hard rock rocks. Hydraulic cylinders 8 of grabs 10 close the jaws 11, capturing the pre-crushed ferromanganese crusts and then, using the hydraulic cylinders 8 of the indicated hinge-link mechanisms 7, transfer the collected ferromanganese crusts to the receiving hopper 2.

To transfer the bottom mining device 1 to a new operating position, the hydraulic cylinders 8 of the lever mechanisms 7 located on the front side 25 and the back side 24 of the receiving hopper 2 raise the grabs 10 above the bedding surface.

Further, the rotation mechanism 5 provides the rotation of the central pivot 4 with the lever mechanisms 7 and grabs 10 attached to it relative to the rack 3 at the required angle and the specified process is repeated.

After the receiving hopper 2 is completely filled, the device 1 can be lifted, for example, with the help of a cable-rope 6, onto the floating craft 22 and there it is unloaded.
