Abstract
The utility model relates to a be used for seabed many metals tuberculosis to excavate first device, it mainly comprises with suction two parts broken. Wherein broken part comprises breakage of water conservancy nozzle and reamer breakage, and the suction part is the inside suction passageway of reamer arm. Originally, excavate the head through broken many metals of the submarine surface tuberculosis of the mode of hydraulic jet and reamer scraping collaborative work, then broken many metals tuberculosis thick liquid is aspirated from reamer arm inside passage and is collected. The utility model discloses simple structure is reliable, easy to carry out, and the ability certain degree promotes the exploitation efficiency of seabed many metals tuberculosis.
Description
Technical field
The utility model relates to a kind of polymetallic nodules digging head unit for exploiting submarine mine material exploitation field.
Background technology
In the world, each Oceanic Bottom stores and extremely enriches mineral matter, and exploration prospect is very tempting, has have an important meaning to the development solving energy crisis and the mankind.And in mineral matter very major part be polymetallic nodules, it is exposed shape, partly burying shape is distributed in the sedimental top layer of abyssal floor, and polymetallic nodules contain various metals, have more the economic exploitation be worth.
Current exploitation seabed polymetallic nodules mode is mechanical type and hydraulic two kinds mainly, and it is fragile that mechanical open excavates tooth, and the deposit taken is excessive, and easily blocking collects mine mouth and collects more complicated; The negative-pressure ward tuberculosis ore efficiency that water conservancy formula utilizes jet to produce is not high, cannot exploit the larger mineral matter of bulk.
Summary of the invention
The utility model object is to overcome the deficiencies in the prior art, and spy provides a kind of digging head for seabed polymetallic nodule mining.Mineral slurry, by after the polymetallic nodules fragmentation of seabed, is drawn into gathering-device from digging head internal pipeline by the mode that employing waterpower and machine instruction statement mining combine.
For achieving the above object, technical scheme provided by the utility model is: a kind of seabed polymetallic nodules digging head unit that is used for comprises reamer, nozzle, reamer arm, spray water channel, suction channel, wherein, reamer is arranged on reamer arm lower end, two nozzles with reamer arm center line for axisymmetrical is arranged on reamer arm interior lower end, reamer arm bosom hollow passageway is suction channel, and suction channel both sides, for spraying water channel, are sprayed water channel and are connected with corresponding nozzle.
The center of described nozzle and the distance at reamer arm center are 1/3 of reamer arm diameter, and the diameter of nozzle and reamer arm junction is 1/8 of reamer arm diameter.
Described injection water channel and corresponding nozzle concentrically axis, diameter is 1/8 of reamer arm diameter, and upper end is connected with high-pressure pump, for nozzle provides high-pressure water jet.
Described injection stream powerful expulsion pressure broken seabed polymetallic nodules, improve crushing and broken speed to a certain extent,
Described suction channel and adjustment arm concentrically axis, diameter is 1/3 of adjustment arm diameter, suction channel upper end with take out stock pump and be connected, the polymetallic nodules be broken in seabed are aspirated by suction channel.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1. reamer, 2. nozzle A, 3. injection water channel A, 4. suction channel, 5. reamer arm, 6. nozzle B, 7. injection water channel B.
Detailed description of the invention
