Embodiment 2

[0063] Such as Figure 6-7 As shown, the seabed polymetallic nodule mining vehicle is the same as the seabed polymetallic nodule mining vehicle of embodiment 1, the difference is that the mechanical conveying device of the transfer device can be replaced by a water jet ore collecting device with a water jet nozzle . The water jet ore collecting device with the water jet nozzle includes a front drainage jet nozzle 23, a rear drainage jet nozzle 24, an ore suction head 25, a centrifugal pump 22 and a pipeline 21, and the front drainage jet nozzle 23 It is relatively installed on the transfer device frame 14 at a certain angle with the rear drainage jet nozzle 24 , and a suction head 25 is installed in the middle of the front drainage jet nozzle 23 and the rear drainage jet nozzle 24 . The front drainage jet nozzle 23 and the rear drainage jet nozzle 24 include multiple groups of water jet nozzles arranged at intervals along the transfer device frame 14 width direction, and the ...

Abstract

The invention relates to the technical field of deep sea mining equipment, in particular to a seabed polymetallic nodule mining vehicle and a mining method thereof. The seabed polymetallic nodule mining vehicle comprises a vehicle body, a crawler walking device, a vehicle head, mineral enrichment devices, a transfer device, an ore storage and unloading device and a seabed topography self-adaption system, wherein the mineral enrichment devices are symmetrically arranged on the two sides of the front end of the vehicle body; the transfer device is arranged behind the mineral enrichment devices; the ore storage and unloading device is installed on the rear portion of the vehicle body; and the above devices cooperate to realize collection and transfer of seabed polymetallic nodules. The seabed polymetallic nodule mining vehicle is a large-range and efficient seabed polymetallic nodule mining vehicle which has a seabed topography self-adaption adjusting function and is suitable for severe seabed conditions and complex topography, the efficient and reliable seabed operation can be achieved, and meanwhile the damage to the deep sea environment in the seabed mining process is reduced.

Description

technical field [0001] The invention relates to the technical field of deep sea mining equipment, in particular to a seabed polymetallic nodule mining vehicle and a mining method thereof. Background technique [0002] The deep seabed is rich in mineral resources, such as polymetallic nodules, polymetallic sulfides, and cobalt-rich crusts. The exploitation of deep sea resources is an effective way to make up for the depletion of land resources, and it is also an inevitable choice in the future. [0003] Polymetallic nodules are widely distributed and have high metal content, which is an extremely important mineral resource in the future. It is often distributed on the seabed sediments on the surface of the seabed at a depth of 3500-6000 meters at the bottom of the world's oceans. It is often in a half-buried state, and some are completely buried by sediments, and the particle sizes vary. Deep-sea mining is faced with the special conditions and complex environment of the deep...
