[0002] Deep-sea polymetallic sulfide ores are rich in gold, silver, copper, lead and other metal elements, and are mainly distributed in the mid-ocean ridges and areas with frequent seafloor activities at 1500-4000 meters below the seafloor. The deposits are formed by the combination of hydrothermal fluids ejected from volcanic craters and cold water. They are in the form of rugged chimney-shaped rocks on the seafloor. The thickness of the formation on the seafloor can reach several meters or even more than ten meters, and has great mining prospects.

[0003] The mining vehicle is the main equipment for mining sulfide ores on the seabed. It integrates cutting, collection, and automatic travel. The first step in the mining process is to cut the metal sulfide ore through the cutting device in front of the mining vehicle body. Due to the extremely harsh seabed conditions, the high corrosion of salt water to the vehicle body, the irregular shape of the stones, the uneven hardness and other factors, the strength of the mining vehicle cutting device and the adaptability to the seabed are relatively strict, and the number of equipment should be minimized to reduce interference between machines.

[0022] like Figure 1-Figure 2 As shown, a cutting device for a seabed sulfide mining vehicle comprises a vehicle frame 1. The present application is connected to the front of the mining vehicle body through the vehicle frame 1. The front end of the vehicle frame 1 is connected to a slewing support 2 by bolts. The top of the slewing support 2 is connected to a slewing frame 3 by bolts. The slewing frame 3 can rotate left and right in the horizontal direction relative to the vehicle frame 1 through the slewing support 2, and can rotate to the left and right up to 66° at most. A slewing cylinder 4 is provided between the opposite sides of the slewing frame 3 and the vehicle frame 1. One end of the slewing cylinder 4 is connected to the oblong hole on the vehicle frame 1 through a connecting seat. The connecting seat and the slewing cylinder connected to the connecting seat can be adjusted through the oblong hole. 4 is fine-tuned, the piston of the slewing cylinder 4 is connected to the side wall of the slewing frame 3, and the pistons on the slewing cylinders 4 on both sides are telescopically coordinated to provide the slewing support 2 with power for horizontal rotation. The side walls on both sides of the slewing frame 3 are rotatably connected with one end of the lifting arm 5 through a pin shaft, and the lifting arm 5 is provided with a connecting shaft 12, and the two ends of the connecting shaft 12 are connected to the pistons on the lifting cylinders 6 on both sides, and the other ends of the lifting cylinders 6 on both sides are connected to the side wall of the slewing frame 3 through a connecting seat, and the lifting and lowering of the lifting arm 5 is powered by the telescopic pistons on the lifting cylinders 6 on both sides. The lifting cylinder 6 can drive the lifting arm 5 to rotate up and down to a maximum of 32°.

[0023] like Figure 3As shown, a pressure compensator 8 and a hydraulic motor 9 are provided in the inner cavity of the lifting arm 5. The pressure compensator 8 is arranged in the lifting arm 5 through a connecting plate 13 and is connected to the spindle box 10 through a pipe. The pressure compensator 8 can balance the oil pressure in the spindle box 10 and the pressure of the external seawater to prevent the spindle box 10 from being damaged by the seawater pressure. The spindle box 10 is connected to the front end of the lifting arm 5 through a connecting flange 11. The hydraulic motor 9 is connected to the inner cavity of the lifting arm 5 through a connecting flange 11. One end of the spindle 101 on the spindle box 10 is connected to the cutting head 7 through a spline, and the other end passes through the connecting flange 11 and is connected to the hydraulic motor 9 through a spline. The rotary cylinder 4, the lifting cylinder 6 and the hydraulic motor 9 are connected to the hydraulic station at the rear of the vehicle body.

[0024] As a further optimization, the outer surfaces of the body frame 1, slewing support 2, slewing frame 3, lifting arm 5, cutting head 7, spindle box 10 and connecting flange 11 are provided with an anodized layer, which can improve the corrosion resistance to seawater.

The slewing cylinder 4 and the lifting cylinder 6 are made of titanium alloy, which reduces the weight while ensuring the strength.

[0025] Working process

[0026] The present application uses a hydraulic motor 9 as a driving device of the cutting head 7, and balances the oil pressure in the spindle box 10 and the pressure of the external seawater through a pressure compensator 8. When cutting the ore, the hydraulic motor 9 drives the spindle 101 in the spindle box 10 to rotate, thereby driving the cutting head 7 to cut the ore. When you want to change the position of cutting the ore, you can use the lifting cylinder 6 and the rotary cylinder 4 to rotate the lifting arm 5 up and down and left and right. Specifically, it is divided into up and down rotation and left and right rotation. When the piston on the lifting cylinder 6 extends, the lifting arm 5 rotates upward with the pin as the center. When the piston on the lifting cylinder 6 retracts, the lifting arm 5 rotates downward with the pin as the center. When the piston of the left rotary cylinder 4 retracts and the piston of the right rotary cylinder 4 extends, the lifting arm 5 rotates to the left through the rotary support 2. When the piston of the left rotary cylinder 4 extends and the piston of the right rotary cylinder 4 retracts, the lifting arm 5 rotates to the right through the rotary support 2.
