[0067] The rotating structure 5 includes a rotating table 51 and a fixed plate 52, the rotating table 51 and the fixed plate 52 are rotatably connected; the rotating table 51 is provided with a hydraulic cylinder at one end of the rotating table 51, and the rotation of the rotating table 51 is pushed by the hydraulic cylinder; and [0068] the rotating table 51 is provided with a bracket 55 on an upper end surface for connecting a supporting arm 2.

[0069] The hydraulic cylinder is a double-outlet rod hydraulic cylinder 54, both ends of the piston rod of the hydraulic cylinder are hingedly connected to the rotating table 51, and a cylinder barrel is rotatably connected to the fixed plate 52.

[0070] The vehicle includes a walking mechanism 1; [0071] a supporting arm 2, provided on the walking mechanism 1, and a rotating structure 5 is provided at the connection between the supporting arm 2 and the walking mechanism 1, for realizing left-right rotation of the supporting arm 2; and up-down rotation can be realized at the same time; [0072] a crushing and collecting mechanism 3, which is provided at the front end of a hydraulic circulation mechanism 4, is used for crushing ores; [0073] a hydraulic circulation mechanism 4, provided on the supporting arm 2 and the walking mechanism 1, for collecting ores and promoting flocculation and precipitation of sediments and reducing the degree of particle diffusion.

[0074] The walking mechanism 1 is activated to move the machine to the area of the ore to be crushed. The supporting arm 2 is driven by the rotating structure 5 to realize left and right rotation so as to adjust the position of the crushing and collecting mechanism 3; at the same time, it can be rotated up and down to adjust the position of the crushing and collecting mechanism 3. After the crushing and collecting mechanism 3 crushes the ore, the hydraulic circulation mechanism 4 preliminarily screens the crushed ore. The ore with larger particles is deposited in the water, while the ore with fine particles is returned to the crushing collecting mechanism 3 through a specific pipe under the action of the circulating water flow, increasing the concentration of fine particles at the crushing collecting mechanism 3, promoting flocculation and precipitation of the deposits, and decreasing the degree of particle diffusion.

[0077] Due to the large contact area of the track 12 with the ground, the friction generated is also large, which enables the track type walking mechanism I to have a large driving force, and be able to overcome various obstacles and resistance. The track type walking mechanism 1 can be flexibly steered and moved, and is able to work in a narrow space with high maneuverability. The track type walking mechanism 1 has a low center of gravity and good stability, and is capable of maintaining continuous work for a long time. The track type walking mechanism 1 can carry various heavy equipment or weaponry, and has a strong carrying capacity. The friction between the track 12 and the traveling surface is large and not easy to slip, which can ensure the stability and safety of the walking mechanism 1.

[0078] The two support beams of the frame 11 are designed as herringbone support beams, which makes the chassis of the mining truck have a larger clearance from the ground, and effectively reduces the phenomenon of cuts on the ground. The herringbone structure can better disperse the load when subjected to force, and improve the overall stability. In the working environment of the mining truck, stability is very important, so as to avoid the equipment in the work of tipping or frame 11 deformation. The design of the herringbone support beam reduces the distribution of concentrated stresses, thereby reducing the possibility of metal fatigue and corrosion and increasing its service life. Herringbone support beams are relatively simple to construct and therefore relatively inexpensive to manufacture. This can effectively reduce costs for large equipment such as mining vehicle.

At the same time, the hydraulic lever two 24 drives the large supporting arm 21 to rotate relative to the rotating table 51 to further adjust the position of the crushing hammer head.

[0082] The small supporting arm 22 is provided with a connection box 41 of the hydraulic circulation mechanism 4.

[0083] The connecting box 41 is provided with a crushing and collecting mechanism 3 for ore crushing; the connecting box 41 is connected by an ore-collecting pipe 422 to avoid the movement of the connecting box 41 being restricted.

[0091] After the crushing and collecting mechanism 3 crushes the ore, the crushed ore falls into the connecting box 41, and enters the ore-collecting pipeline 42 through the ore-collecting port 411. The ore-collecting pipeline 42 conveys the crushed ore to the screening and separating bin 43. Inside the screening and separating bin 43, the ore undergoes screening by the first screening plate, the second screening plate and the third screening plate. The screened ore enters the ore storage bin 44, and the lower part of the ore storage bin 44 is provided with an ore outlet 441, which is connected to an ore output pipe to convey the screened ore to the outside. The multi-row outlet pipe 45 is provided in the upper part of the connection box 41, which is connected to the hydraulic pipe 47. A high-pressure jet nozzle 48 is connected to one end of the multi-row outlet pipe 45 for generating a high-velocity water flow. The hydraulic suction pump 46 draws seawater and sediment from the screening and separation bin 43, which is ejected from the high-pressure jet nozzle 48 through the hydraulic pipe 47 and the connected multi-row outlet pipe 45. This high-velocity water flow further breaks up fine ore particles while promoting flocculation and sedimentation of the sediments and reducing the degree of particle spreading. The seawater sediment that has been repeatedly circulated and flowed maintains a high concentration of sediment particles in the nearby crushing drum 61, which improves the recovery efficiency of the ore. The hydraulic circulation mechanism 4 achieves efficient treatment and utilization of the ore through a series of screening, separation, storage and circulation flow processes. This design enables the machine to be better adapted to different working environments and demands, further enhancing its working efficiency and stability.
