DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the apparatus for mining, washing and lifting manten balls deposited on the seabed according to the present invention will be described below with reference to the drawings.

In Fig. 1, numeral 1 is a mining, washing, ore lifting device according to the present invention.

This mining washing and ore lifting device 1 has an ore lifting device 4 for manganese balls A and a wire rope 5 for settling and pulling up connected to a mining boat 3 on the sea from a mining vehicle 2 running on the deep seabed. 〃) A wire rope 5.7 for supporting a support vessel 6 or a buoy at sea is connected to a pump P1 in each vessel.
It is connected to a winch etc. as appropriate.

Further, the ore lifting device 4 has a venturi device 9 at a proper position in the ore lifting pipe 8, as shown in FIG.

This venturi', l-4f9 has a jacket 11 around the widening venturi tube 10, and is sloped at the partition wall between the jacket 11 and the venturi tube 10 so as to open upward in the venturi tube 10. An injection nozzle 12 having a shape of
Inject high pressure water or compressed air through the
The manganese balls A in the collection box 14, which will be described later, are sucked up together with the seawater by the negative pressure generated at this time. .

In this case, either high-pressure water or compressed air may be used. For example, compressed air may be used for the Venturi device 9 near the sea surface, and high-pressure water may be used for the Venturi device 9 located below. You may also do so.

On the other hand, the mining vehicle 2 is rotatably mounted on a frame 16 in which a pair of left and right crawlers 15.15 are framed, as shown in FIGS. 3 to 5.
is rotatably driven by a hydraulically driven motor 17 via a suitable power transmission device 18 such as a belt.

This hydraulic motor 17 is installed on a mounting plate 19 fixed to the frame 16, and is driven by pressure water supplied from the collection boat 3 through a water pipe 17'.

Further, an appropriate number of support rods 20 are erected on the frame 16, and the wire ropes 5.7 are tied to the support rods 20, and both sides of the frame 16 are extended forward. A sled 21 is mounted so as to be able to run freely on the uneven seabed, and an appropriate number of hoes 22 are installed between the frames 16 of the sled 21 by means of shaft rods 23 located behind the sled 21.

Further, the hoe 22 is placed behind the hoe 22, and the excavated manganese balls A are collected in the collection box 1 behind the frame 16.
A screw conveyor 24 is provided to transfer the materials into the container.

This screw conveyor 24 has 24', 24", 24"ζ horizontally suspended intermittently between the blades, and is supported by the frame 16. 25
Furthermore, this porous cylinder 25 is surrounded by a steel cover 26 with a spacer 35 interposed therebetween to maintain appropriate spacing.

The porous cylindrical body 25 has a bottom portion on one side cut out to form a mining opening B'.

The cover 26 has a portion at the mining opening B.
It is widened in the shape of < and has an opening at the bottom, and the hem 27 of this opening is widened to the end so that separated gravel, mud, etc. can be discharged.

The rear end of the screw conveyor 24 has a crushing part 28 , and this crushing part 28 has a rotary crushing plate 29 fixed to the rotating shaft of the screw conveyor 24 and rotatable, and a rotary crushing plate 29 fixed to the frame 16 . In addition to the fixed crushing plate 30, the rotary crushing plate 29 and the fixed crushing plate 30 are formed to be thick and rigid, and are disposed facing each other with an appropriate distance between them.

In this case, if the rotary crushing plate 29 is arranged at an appropriate angle with respect to the fixed crushing plate 30, the manganese balls A can be easily received within this interval and the crushing effect is also good.

A hydraulic motor 31 is connected to the screw conveyor 24 and driven to rotate, and between the screw conveyor 24 and the hoe 22, the hoe 22 excavates the ground manganese balls A to the screw conveyor. A fan-shaped inclined plate 32 is provided to feed the material into the container 24.

The lower part of the crushing section 28 is communicated with the collection box 14, and the manganese A crushed into an appropriate size by the crushing section 28 is intended to be temporarily stored in the collection box 14.

Furthermore, it goes without saying that the ore lifting pipe 8 is connected to the collection box 14.

The canned water cam motor 17.31 is connected to the pump P of the collection boat 3 through a water cylinder 31', and the system water conveyor 240 is controlled by adjusting the flow rate of water in the collection boat 3. The rotation speed and the traveling speed of the crawler 15 are freely controlled.

Said ore lifting pipe 8 and wire rope 5.
6 is installed to reduce the slack in the ore lifting pipe 8 and wire rope 5.7 as much as possible.

By the way, when the manganese balls A are transferred to the screw conveyor 24, fine particles and mud that float without settling may also be sucked up to the sea together with the manganese balls A.

[For this reason, the waste water after the motor is driven is directly passed through the water pipe 1T.]
31'' into the crushing section 28 from the nozzle 1r4'31'' to increase the water pressure inside the crushing section 28 above that of the screw conveyor 24 to prevent fine particles and mud from entering the collection box 14. do.

When a hydraulic motor is used instead of the hydraulic motor 17.31, a pump driven by the hydraulic motor drives the nozzle 1? , all you have to do is make the nearby seawater spout from "31".

Note that the hoe 22 may be of a rotary type driven by a fixed low-water cam motor or the like.

In the mining apparatus having the above configuration, first, in order to prevent damage to the ore lifting pipe 8 etc. due to water pressure, the hydraulic motor 17 is started by hydraulic operation of the pump P on the collection boat 3, and the crawler 15 is driven to rotate. In this state, the wire rope 5.7 is let out from the winch and lowered until it reaches the deep seabed.

Next, on the collection vessel 3, the amount of water supplied to the hydraulic motor 17 and the opening/closing operation of the valves are adjusted to arbitrarily control the traveling speed while traveling on the deep seabed.

Along with this running, the hoe 22 digs up the manganese balls A, raises them onto the fan-shaped inclined plate 32, and sends them into the collection box 14 by the screw conveyor 24.

At this time, the manganese balls A are attached to the screw conveyor 24 and the swinging rods 24' and 24''.

24"' in the porous cylindrical body 25 while being shaken and subjected to a disturbance effect, the material is washed with seawater to separate sand, gravel, mud, etc. that may be mixed in or adhere to the material.

The separated gravel, mud, etc. pass through the mesh of the porous cylindrical body 25 and pass between the porous cylindrical body 25 and the cover 26, and are then discharged from the opening at the bottom to the seabed surface. The balls A are sent into the collection box 14 through the crushing section 28, but in the crushing section 28, as the rotating crushing plate 29 rotates, a large manganese is sent between the rotating crushing plate 29 and the fixed crushing plate 30. The balls A are compressed and crushed, thereby preventing clogging of the ore lifting pipe 8.

The manganese balls A stored in the collection box 14 are lifted by a venturi device 9 to a collection ship on the sea together with seawater.

In this case, only the peripheral wall and top wall of the collection box 14 have a large number of small holes, and the bottom wall does not have small holes. There is no problem of sucking up other items at the same time.

6 and 7 show another embodiment of the mining vehicle 2', in which a hoe 22 is arranged behind the crawler 15 and the hoe 22 is arranged behind the crawler 15.
2, the manganese balls A excavated in step 2 are sent to the collection box 33, and then the screw conveyor 2 is used to transport the manganese balls A into the collection box 14 placed in front of the crawler 15.
4.

In this case, the trapping box 33 is made of a board with a porous bottom so that abstracts, mud, etc. can be discharged from the inside of the box, or a rudder-shaped one is used.

On the other hand, the screw conveyor 24 is surrounded by a perforated cylindrical body 25 and a cover 26, which is the same as in the previous embodiment. Discharge chute 34.34
is formed.

In the reporter's example, a fishing boat at sea 3 and a mining vehicle 2.2
A Venturi device having the same structure as above is connected to the hydraulic motor 17.31 driving the 17. After sucking in seawater near the seabed and rotating the hydraulic motor 17.31, it may be sucked up to the sea or to a collection vessel using a suction pipe and drained.

With this configuration, mining vehicles due to the topography of the seabed2.2
The hydraulic motor 17 installed on the collection vessel 3 can be operated in a specified manner without being affected by changes in the depth of the water.
It would be extremely convenient if the power source for driving the hydraulic motor 17.31 could be made relatively compact, and the output of the hydraulic motor 17.31 would be reduced.

In order to prevent fine particles and mud from entering the hydraulic motor 17, 31 and the collection box 14, nozzles 17'' and 31 are installed.
It is preferable to use a pump equipped with a speed reducer for spouting water into the crushing section 28 or the like from "."
