With the advancement of science and technology and the gradual reduction of easily mined mineral resources on land, seabed mining has attracted increasing attention. Existing seabed mining usually uses mining vehicles to carry out seabed excavation and mining operations.

[0051] Embodiment 1

[0052] like Figure 1 As shown, this embodiment provides a replaceable mining rake mechanism, which is used to be connected to a mining vehicle body 10. The mining vehicle body 10 is the main part of an underwater mining vehicle and is mainly used for underwater mobile mining. The mining rake mechanism can be replaceably arranged on the left and right sides of the front end of the mining vehicle body 10. Figure 1 , Figure 2 , Figure 3 As shown, the mining rake mechanism mainly includes: a mounting frame 100, a main power member 200, a mining rake 300 and a locking assembly 400. The mounting frame 100 is used to connect to the mining vehicle body 10, and mainly serves as a fixed part to provide a mounting position for other components. It can be used as a part of the front structure of the mining vehicle body 10. The main power member 200 is arranged on the mounting frame 100, and a docking portion 210 is arranged on the main shaft of the main power member 200; the main power member 200 can be a hydraulic motor, which is fixedly connected to the mining vehicle body 10 through the mounting frame 100. When the mining rake mechanism is replaced, it does not need to be replaced, so that the hydraulic pipeline will not be changed, and there will be no problem of pipeline disassembly and assembly during the replacement process, thereby making the disassembly and assembly process simpler and easier to implement. The mining rake 300 is detachably connected to the main shaft of the main power member 200 through the docking part 210, and rotates through the drive of the main power member 200; the mining rake 300 is the main replacement structure, and after being connected to the main power member 200 through the docking part 210, it rotates through the drive of the main power member 200, thereby realizing the mining function. The locking assembly 400 is set on the mounting frame 100, and clamps or loosens the mining rake 300 connected to the main power member 200; when the mining rake 300 needs to be replaced, the locking assembly 400 is in a loose state, so that the mining rake 300 can be taken out for easy replacement; when the mining rake 300 is replaced, the locking assembly 400 is in a locked state, so that the mining rake 300 can be stably set, and stable rotation is achieved through the drive of the main power member 200.

[0053] like Figure 1 , Figure 2 , Figure 3 As shown, the replaceable mining rake mechanism of this embodiment is provided with a mounting frame 100 on the mining vehicle body 10, and the main power member 200 is provided on the mounting frame 100, so that the mining rake 300 can be detachably connected to the main power member 200 through the docking part 210. The mining rake 300 is clamped or loosened by the locking assembly 400. When the mining rake 300 is worn during the kelp mining process, the mining rake 300 is loosened by the locking assembly 400, and the worn mining rake 300 is removed from the docking part 210 by an underwater robot, and then replaced; a new mining rake 300 is installed on the docking part 210 by the underwater robot, and the mining rake 300 is clamped by the locking assembly 400. The worn mining rake mechanism is replaced in time underwater, which greatly optimizes the replacement method of the mining rake mechanism and makes the seabed replacement of the mining rake mechanism more convenient.

[0054] like Figure 2 , Figure 3 , Figure 4As shown, further, one axial end of the mining rake 300 of this embodiment is a mounting end 310, and the mining rake 300 is detachably connected to the docking portion 210 through the mounting end 310. A bearing seat 320 is provided on one side of the mounting end 310, and rake teeth 330 are provided on the side of the bearing seat 320 away from the mounting end 310. The bearing seat 320 is used to dock with the locking assembly 400 so that the mining rake 300 can rotate. Therefore, a bearing 321 is provided in the bearing seat 320, and the mining rake 300 is rotatably connected to the bearing seat 320 through the bearing 321.

[0055] like Figure 2 , Figure 3 , Figure 4 As shown, the locking assembly 400 of this embodiment specifically includes: a driving part 410, a connecting rod part 420 and a clamping part 430. The driving part 410 is arranged on the mounting frame 100. The driving part 410 can specifically be a hydraulic cylinder, and the piston rod of the hydraulic cylinder is extended and retracted by hydraulic drive. The hydraulic cylinder is fixedly arranged on the mounting frame 100 along the up and down directions. The connecting rod part 420 is connected to the driving part 410 and moves by the driving of the driving part 410; when the piston rod of the hydraulic cylinder is extended and retracted, power is provided to the connecting rod part 420. The clamping part 430 is connected to the connecting rod part 420, and clamps or releases the bearing seat 320 by the driving of the connecting rod part 420. The movable connecting rod part 420 drives the clamping part 430 to move. When the mining rake 300 needs to be replaced, the driving part 410 drives the connecting rod part 420 to drive the clamping part 430 to form a loose state; after the mining rake 300 is replaced, the driving part 410 drives the connecting rod part 420 to drive the clamping part 430 to form a locked state, so that the bearing seat 320 is stably fixed and the mining rake 300 can rotate stably.

[0056] like Figure 3 , Figure 4 , Figure 5As shown, further, the clamping portion 430 of this embodiment specifically includes: a first clamping seat 431 and a second clamping seat 435. The first clamping seat 431 is rotatably connected to the mounting frame 100 through a first hinge position 432, and is hinged to the connecting rod portion 420. A first gear portion 433 is provided on the first clamping seat 431, and the first gear portion 433 rotates around the first hinge position 432. The second clamping seat 435 is rotatably connected to the mounting frame 100 through a second hinge position 436, and a second gear portion 437 is provided on the second clamping seat 435. The first clamping seat 431 and the second clamping seat 435 enclose a clamping space 500, and the clamping space 500 is used to clamp the bearing seat 320. The second gear portion 437 is meshed with the first gear portion 433, so that the rotating first clamping seat 431 drives the second clamping seat 435 to rotate, so as to open or close the clamping space 500. A hinge platform 434 is provided on the upper surface of the first clamping seat, and the connecting rod portion 420 is hinged on the hinge platform 434. The rear sides of the first clamping seat and the second clamping seat are hinged respectively, and an opening 510 is formed on the front side. Therefore, the front side of the clamping space 500 forms an opening 510 for the bearing seat 320 to enter and exit during installation. For the convenience of structural description, the direction from front to back is the entry direction of the bearing seat 320, and the direction from back to front is the removal direction of the bearing seat 320. The first clamping seat 431 and the second clamping seat 435 are respectively rotated by the push of the connecting rod 420, and the first clamping seat 431 and the second clamping seat 435 rotate in opposite directions under the action of the first gear portion 433 and the second gear portion 437, so that the opening 510 of the clamping space 500 can be opened or closed. When the clamping space 500 is opened, the bearing seat 320 can smoothly enter the clamping space 500 from the front to the back, and then the first clamping seat 431 and the second clamping seat 435 are tightened to fix the bearing seat 320 in the clamping space 500. Through this structure, the first clamping seat 431 and the second clamping seat 435 can rotate synchronously in opposite directions, and the bearing seat 320 can be easily centered during the clamping process, thereby ensuring the installation accuracy of the bearing seat 320.

[0057] like Figure 4 , Figure 5 , Figure 6As shown, further, the outer surface of the bearing seat 320 of this embodiment is provided with a plurality of clamping limit surfaces 322, and the clamping space 500 has a plurality of clamping inner walls 501 matching the clamping limit surfaces 322, and the bearing seat 320 is limited and fixed in the clamping space 500 by the clamping limit surfaces 322 and the clamping inner walls 501. In the specific structure, the plurality of clamping limit surfaces 322 of the clamping space 500 can form a hexagonal clamping space 500, and the inner wall on the side of the opening 510 is separated by the opening 510, so that an inclined clamping surface is formed on the inner wall of the first clamping seat 431 and the second clamping seat 435 on the side of the opening 510, and the polygonal clamping inner wall 501 is adopted, so that the bearing seat 320 can be better limited in the clamping space 500, and the bearing seat 320 will not loosen after being clamped, thereby ensuring the connection stability of the bearing seat 320.

[0058] like Figure 4 , Figure 5 , Figure 6 As shown, in the specific structure, the first clamping seat 431 is located at the opening 510 of the clamping space 500 and is provided with an upper stop block 520, and the second clamping seat 435 is located at the opening 510 of the clamping space 500 and is provided with a lower stop block 530, the inner side of the upper stop block 520 and the inner side of the lower stop block 530 are both inclined clamping surfaces, and the upper stop block 520 cooperates with the lower stop block 530 to open or close the opening 510. In the closed state, the bearing seat 320 located in the clamping space 500 can be clamped by cooperating with the inner side of the upper stop block 520 and the inner side of the lower stop block 530.

[0059] like Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, further, the mounting frame 100 of this embodiment is provided with a mounting guide frame 110, and the mounting guide frame 110 is located on one side of the clamping portion 430. In the specific structure, the mounting guide frame 110 can be located on the left or right side of the clamping portion 430, and in this embodiment, it is located on the side close to the main force member 200. The mounting guide frame 110 is provided with a push-in guide surface 111 and a guide support surface 112, and the guide support surface 112 is arranged on the side of the push-in guide surface 111 facing the entry direction, so the guide support surface 112 is located on the rear side of the push-in guide surface 111. The push-in guide surface 111 is inclined and is used to guide the bearing seat 320 to the guide support surface 112; in the specific structure, the push-in guide surface 111 gradually rises in the direction from front to back, so that it has a larger opening angle and is convenient for the bearing seat 320 to push against it, so that the bearing seat 320 can smoothly enter the guide support surface 112. The guide support surface 112 is used to support the bearing seat 320. The thickness of the bearing seat 320 is relatively large (thickness in the left-right direction). Therefore, a part of the area on one side of the left-right direction of the bearing seat 320 is supported by the guide support surface 112, and a part of the area on the other side enters the clamping space 500. When the bearing seat 320 is pushed onto the guide support surface 112, the central axis of the mining rake 300 is aligned with the rotation center of the rotation axis of the main force member 200, so that the mining rake 300 and the docking part 210 are aligned in height, and the installation process of the mining rake 300 and the docking part 210 is more convenient.

[0060] In the present embodiment, in the open state, the lower stopper block 530 is lower than the push-in guide surface 111. In this way, during the movement of the bearing seat 320, the lower stopper block 530 will not interfere with the bearing seat 320, so that the movement of the bearing seat 320 is smoother.

[0061] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, further, the connecting rod portion 420 of this embodiment specifically includes: a first driving plate 421 and a driving connecting rod 423. The first driving plate 421 is connected to the driving portion 410, and a U-shaped groove 422 is provided on the first driving plate 421. One end of the driving connecting rod 423 is movably connected in the U-shaped groove 422, and the other end is hinged on the clamping portion 430. The connecting rod structure is used to realize the driving function, and the structure is simple.

[0062] like Figure 2 , Figure 4 , Figure 5 , Figure 7As shown, further, the docking portion 210 of this embodiment specifically includes: a joint seat 211 and a C-shaped socket 212. The joint seat 211 is connected to the main shaft of the main force member 200, and the C-shaped socket 212 is provided on the joint seat 211. A positioning shaft surface 311 is provided at one end of the mining rake 300, and the positioning shaft surface 311 is located at the mounting end 310. The mining rake 300 is inserted and limited in the C-shaped socket 212 through the positioning shaft surface 311. In the specific structure, a positioning plane 213 is also provided on the C-shaped socket 212, so that the mounting end 310 of the mining rake 300 can be limited after being inserted into the C-shaped socket 212. The C-shaped socket 212 is provided as a bell mouth 214, which is convenient for guiding the insertion of the mounting end 310 of the mining rake 300. It should be noted that the positioning axis surface 311 on the mounting end 310 of the mining rake 300 is also the positioning reference surface for the underwater robot to hold the mining rake 300. When the underwater robot holds the mining rake 300, the positioning axis surface 311 is always used as a reference to keep the mining rake 300 relative to the C-shaped socket 212, so that the mounting end 310 of the mining rake 300 can be accurately inserted into the connector seat 211 to achieve connection.

[0063] like Figure 4 , Figure 5 , Figure 7 As shown, further, a stop block 220 is provided on the outer wall of the joint seat 211 of this embodiment. The mining rake mechanism also includes a movable stopper 600, which blocks or gives way to the stop block 220 by moving. By cooperating with the stop block 220 and the movable stopper 600, the position of the docking portion 210 can be fixed when the mining rake 300 needs to be disassembled, so that the C-shaped socket 212 on the docking seat can be at a predetermined position and face the front side, so that the replacement position of the mining rake 300 is unified and consistent with the entry direction and removal direction of the bearing seat 320.

[0064] like Figure 2 , Figure 5 , Figure 7As shown, the movable stopper 600 of this embodiment specifically includes: an articulated rod 610 and an elastic return member 620. The articulated rod 610 is articulated on the mounting frame 100, and a stopper 611 and a pressing rod 612 are respectively provided at both ends of the articulated rod 610. The pressing rod 612 is connected to the locking assembly 400, and the stopper 611 is driven away from the stopper 220 by the locking assembly 400; the elastic return member 620 connects the mounting frame 100 and the articulated rod 610, and when the locking assembly 400 releases the mining rake 300, the articulated rod 610 is pulled to make the stopper 611 block the stopper 220. In the specific structure, a pressing plate 411 is provided on the piston shaft of the driving part 410, and the pressing plate 411 extends in the left-right direction. The pressing plate 411 is located above the pressing rod 612. The pressing plate 411 is driven by the driving part 410 to squeeze the pressing rod 612, so that the stopper 611 at the other end can be lifted under the lever action of the hinge rod 610. Therefore, the stopper 611 is driven upward away from the stop block 220 through the hinge rod 610 by the downward movement of the pressing plate 411. When the pressing plate 411 moves downward, the connecting rod part 420 presses the clamping part 430 downward under the drive of the driving part 410, thereby clamping the bearing seat 320. In this way, the downward drive of the driving part 410 can realize the connection of the mining rake 300 and release the blocking of the stop block 220 at the same time. By the upward movement of the pressing plate 411, the hinge rod 610 drives the stop block 611 to block the front side of the stop block 220 under the pull of the elastic return member 620. When the pressing plate 411 moves upward, the connecting rod part 420 pulls the clamping part 430 upward under the drive of the driving part 410, thereby releasing the bearing seat 320. In this way, the mining rake 300 is released and the stop block 220 is blocked while the upward drive of the driving part 410 is used, which makes the disassembly and assembly of the mining rake 300 more convenient.

[0065] In addition, an arc surface 412 is provided at one end of the pressing plate 411 facing the hinge rod 610 . When the pressing plate 411 moves downward, the pressing rod 612 is squeezed by the arc surface 412 , so that the pressing rod 612 can rotate smoothly.

[0066] Embodiment 2

[0067] like Figure 1 As shown, this embodiment provides an underwater mining vehicle, which includes a mining vehicle body 10 and at least two replaceable mining rake mechanisms as described above. The at least two mining rake mechanisms are respectively arranged on the left and right sides of the head end of the mining vehicle body 10.

[0068] In summary, the present application provides a replaceable mining rake mechanism and underwater mining vehicle. When the mining rake is worn during kelp mining, the mining rake is loosened by the locking assembly, and the worn mining rake is removed from the docking part by an underwater robot, and then replaced; a new mining rake is installed on the docking part by the underwater robot, and the mining rake is clamped by the locking assembly.
