The development of deep-sea mining equipment faces multiple challenges, especially in finding a balance between resource acquisition and environmental protection.

Each row includes a plurality of crushing components 1212 arranged at intervals along the circumferential direction of the cylinder 1211.

[0055] Specifically, such as Figures 6-8 As shown, the cylinder 1211 is rotatably mounted on the left end of the mounting frame 15. The motor 122 is mounted on the mounting frame 15 and its output shaft is connected to the cylinder 1211. Thus, the motor 122 drives the cylinder 1211 to rotate on the mounting frame 15. The cylinder 1211 is detachably mounted on the mounting frame 15, which allows the structure of the crushing roller 121 to be replaced or adjusted according to the characteristics of the target ore to meet the mining needs of different types of deep-sea ore and ensure the crushing efficiency of the crushing roller 121. The crushing component 1212 includes a first section 1213 and a second section 1214. The first section 1213 is fixed to the outer periphery of the cylinder 1211, and the second section 1214 has a sharp tip to make the crushing component 1212 generally pick-shaped. The sharp tip is suitable for efficiently crushing seabed sediments. Multiple crushing components 1212 are arranged in multiple rows along the front-to-back direction. Each row includes several crushing components 1212 arranged circumferentially along the cylinder 1211, so that the crushing components 1212 can be evenly distributed in the cylinder 1211, thereby enabling all-round and multi-level crushing of seabed sediments, adapting to... Various seabed geological conditions; in addition, the pick-shaped cutting tool 1212, when the cylinder 1211 starts to rotate, the sharp tip of the second section 1214 first penetrates the seabed sediment layer, separating the ore from the surrounding mud and sand, and can effectively lift the ore from the sediment layer, reducing resistance and energy consumption during the excavation process. The continuously rotating cylinder 1211 can maintain an efficient working rhythm during the excavation process, so that the ore can be dug out quickly, ensuring the crushing efficiency of the crushing roller 121. Whether it is soft mud or hard rock, it can be effectively crushed, improving the applicability of the crushing component 12.

[0057] In some embodiments, the nozzle assembly 13 comprises a high-pressure water pump 131, a first nozzle assembly 132 and a second nozzle assembly 133.

[0058] The high-pressure water pump 131 is arranged in the walking assembly 11. Specifically, as shown in Figure 4 the high-pressure water pump 131 is fixedly installed in the walking assembly 11.

[0059] The first nozzle assembly 132 comprises a first nozzle pipe 1321 and a first nozzle 1322, both ends of the first nozzle pipe 1321 are in communication with the high-pressure water pump 131 and the first nozzle 1322 respectively, the first nozzle 1322 is arranged on the side of the third pipe 141 adjacent to the crushing assembly 12, and the first nozzle 1322 extends from top to bottom and is inclined towards the side away from the crushing assembly 12. Specifically, as shown in Figures 3-5As shown, the first spray head 1322 is made of high-pressure and corrosion-resistant material to ensure long-term use without damage in deep-sea environment. The inlet of the first spray pipe 1321 is connected to the outlet of the high-pressure water pump 131. The first spray head 1322 is provided in multiple numbers and arranged in sequence along the front-rear direction on the left side of the outlet of the third pipe 141. The first spray head 1322 extends from top to bottom and is inclined to the right. The multiple first spray heads 1322 are all in communication with the first spray pipe 1321, so that the jet water is sprayed out through the first spray head 1322 via the first spray pipe 1321. The arrangement of the first spray head 1322 can make the water flow inclined to the right. The angle and jet force of the first spray head 1322 can be adjusted to adapt to different types of sediment layers and ore densities. The water pressure and jet angle can also be adjusted. The first spray head 1322 can accurately control the impact force, which can effectively lift the ore without causing excessive disturbance to the surrounding sediment layer. Therefore, through the angle and position arrangement of the first spray head 1322, the loose ore can be effectively lifted from the sediment layer, ensuring that the water flow can penetrate the sediment layer and generate sufficient thrust to lift the ore.

[0060] The second spray head assembly 133 includes a second spray pipe 1331 and a second spray head 1332. The two ends of the second spray pipe 1331 are in communication with the high-pressure water pump 131 and the second spray head 1332, respectively. The second spray head 1332 is arranged on the side of the third pipe 141 away from the crushing assembly 12. The second spray head 1332 extends from top to bottom and is inclined towards the side adjacent to the crushing assembly 12. Specifically, as shown in Figures 3-5 The inlet of the second spray pipe 1331 is connected to the outlet of the high-pressure water pump 131. The second spray head 1332 is provided in multiple numbers and arranged in sequence along the front-rear direction on the right side of the outlet of the third pipe 141. The second spray head 1332 extends from top to bottom and is inclined to the left. The multiple second spray heads 1332 are all in communication with the second spray pipe 1331, so that the jet water is sprayed out through the second spray head 1332 via the second spray pipe 1331. The arrangement of the second spray head 1332 can make the water flow inclined to the left. The second spray head 1332 can generate a reverse water flow forming a "water wall", effectively preventing the ore from scattering backward, so that the ore is concentrated near the barrel body 1211, facilitating collection. The combined flow of the first spray head 1322 and the second spray head 1332 forms an upward thrust, lifting the ore and guiding it to the inlet of the third pipe 141, ensuring that the ore can be smoothly transported into the third pipe 141. In addition, the high-pressure water jet sprayed by the first spray head assembly 132 and the second spray head assembly 133 is not only used for lifting and guiding the ore, but also can quickly clean the silt and sediment on the surface of the barrel body 1211, reducing the friction between the barrel body 1211 and the ore, and improving the working efficiency. Through the scouring of the high-pressure water flow, the barrel body 1211 can be kept clean, avoiding jamming and wear caused by silt accumulation.

[0061] The utility model discloses a deep sea mining system 100 has the following advantages through the setting of broken roll 121 and nozzle assembly 13.

[0062] 1. Reduce disturbance: broken roll 121 mainly undertakes the excavation task, and the high-pressure water jet of nozzle assembly 13 is used as an auxiliary tool, which reduces the direct impact of water jet on the sediment layer. The ore excavated by broken roll 121 is cleaned and guided by water jet, which can better control the impact on the seabed sediment.

[0063] 2. Precise operation: through the cooperative work of machinery (broken roll 121) and water jet (nozzle assembly 13), precise excavation and cleaning can be realized, and disturbance to non-target areas is reduced. The reasonable configuration of front and rear rows of jets ensures that water flow impact is only carried out in necessary areas, protecting the surrounding seabed ecology.

[0064] 3. Reduce ecological damage: pure water jet deep sea mining system 100 often causes a large amount of sediment to be suspended, affecting the seabed ecosystem. By combining mechanical excavation and water jet, the design can reduce the range of sediment suspension and diffusion, and reduce the damage to the seabed ecological environment.

[0065] 4. Sediment control: the nozzle assembly 13 can be designed with multiple filtering and adjusting functions, which can control the intensity and direction of water flow, avoid excessive disturbance of the sediment layer, and protect the survival environment of seabed organisms.

[0066] 5. Comprehensive protection measures: in addition to reducing physical disturbance, the utility model also considers environmental factors such as water quality and noise. Nozzle assembly 13 can be equipped with noise reduction and vibration reduction equipment to reduce noise pollution generated during mining. In addition, the water jet of nozzle assembly 13 uses water that has been treated and filtered to ensure that no harmful substances are introduced, protecting the marine environment.

[0067] Therefore, by combining broken roll 121 and nozzle assembly 13, the design achieves the dual goals of efficient mining and environmental protection. The water jet system not only improves mining efficiency, but also reduces damage to the seabed sediment layer and ecosystem.
