Abstract
Description
Technical Field
[0001] This invention relates to the field of mining vehicle technology, and specifically to a deep-sea polymetallic nodule tracked mining vehicle. Background Technology
[0002] The deep seabed contains abundant mineral resources, mainly including polymetallic nodules, cobalt-rich crusts, and polymetallic sulfides. Its reserves of rare metals such as cobalt, manganese, and nickel are far greater than those on land, making it an effective way to make up for the depletion of land resources.
[0003] Polymetallic nodules are widely distributed and have high metal content, making them an extremely important mineral resource for the future. They are found in seabed sediments at depths of 3500-6000 meters, exhibiting varying grain sizes. Deep-sea mining faces unique conditions and a complex environment. Extracting polymetallic nodules from the extremely soft seabed sediments with minimal disturbance requires significantly different mining techniques, equipment, and operating environments, presenting much higher demands and greater challenges.
[0004] In conclusion, there is an urgent need for a new type of mining vehicle to improve the problems of limited mining range, low mining efficiency, and poor adaptability to seabed terrain of the existing mining vehicles. Summary of the Invention

[0006] Specifically, the present invention provides a tracked mining vehicle for deep-sea polymetallic nodules, comprising:
[0007] The vehicle frame includes a tracked walking device located at the bottom of the vehicle frame for driving the mining vehicle to move in a set direction; a hydraulic ore collection device located at the front end of the main frame for collecting polymetallic nodules; a material storage mechanism located in the middle of the main frame for collecting polymetallic nodules from the seabed and enriching them in the middle area of the main frame; and a seabed terrain adaptive device located at the front end of the vehicle frame, including a linear electric cylinder, a linear sliding guide rail, a connecting bracket, and a displacement sensor, for receiving information from the seabed terrain exploration equipment installed on the hydraulic ore collection device and controlling the height of the hydraulic ore collection device above the seabed.
[0008] The vehicle frame serves to support and mount other functional components. The tracked walking device is independently driven by a motor, enabling the vehicle to move. The hydraulic ore-gathering device is located at the front end of the main frame. Another advantage of this invention is the design of a seabed terrain adaptive device, which can receive information from the seabed terrain exploration equipment installed on the hydraulic ore-gathering device and use it to control the height of the hydraulic ore-gathering device above the seabed, thus achieving adaptive adjustment of the mining vehicle.

[0010] Furthermore, the hydraulic ore collection device includes an electrically driven water pump, a conveying hose, a jet nozzle, a conveying nozzle, and a conveying channel connected in sequence.
[0011] Preferably, the jet nozzle is a double-row jet collection head.

[0015] Furthermore, the deep-sea polymetallic nodule tracked mining vehicle of the present invention also includes an adaptive control system and a driver, and two sealed cylindrical tubes are provided at the rear of the vehicle frame, and the adaptive control system and driver are located inside the sealed cylindrical tubes.
[0016] Preferably, the width of the hydraulic ore collection device is 2.5 times that of the tracked walking device.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] This invention discloses a tracked mining vehicle for deep-sea polymetallic nodules. During operation, a hydraulic ore-gathering device at the front of the vehicle uses two jets to collect polymetallic nodules from the surface into a guide channel area. The nodules are then conveyed through a conveying nozzle and transported to a storage and unloading device, where sediment and minerals are separated. This deep-sea polymetallic nodule mining vehicle is well-suited for harsh seabed conditions and complex terrain, offering a large collection range, high mining efficiency, and adaptive adjustment to seabed terrain. It enables efficient and reliable seabed operations while minimizing environmental damage during the mining process. Attached Figure Description
