[0038] Example 1

[0039] like Figure 1 、 Figure 2 As shown, this embodiment provides a replaceable front shovel structure for connection to a mining vehicle body 10. The mining vehicle body 10 is the main component of an underwater mining vehicle, primarily used for underwater mobile mining. This front shovel structure is replaceably mounted at the front end of the mining vehicle body 10. Therefore, the front shovel structure primarily comprises a mounting portion 100 mounted on the mining vehicle body 10, a front shovel body 200, and a docking member 210 mounted on the front shovel body 200. The docking member 210 is detachably connected to the mounting portion 100. The front shovel body 200 has an inclined surface at its front end. Therefore, when the rear end of the front shovel body 200 is connected to the mining vehicle body 10, the inclined surface is used to scoop ore. The rear end of the front shovel body 200 is detachably connected to the mining vehicle body 10 through the mating member 210 and the mounting portion 100, facilitating underwater replacement of a worn front shovel body 200.

[0040] like Figure 1 、 Figure 2As shown, the replaceable front shovel structure of this embodiment is provided with a mounting portion 100 on the mining vehicle body 10 and a docking member 210 on the front shovel body 200. The docking member 210 is detachably connected to the mounting portion 100, so that the front shovel body 200 can be detachably connected to the mining vehicle body 10 through the cooperation of the docking member 210 and the mounting portion 100, thereby facilitating the front shovel body 200 to shovel ore. When the front shovel body 200 needs to be replaced, the docking member 210 is separated from the mounting portion 100 by an underwater robot, thereby separating the front shovel body 200 from the mining vehicle body 10. The new front shovel body 200 hoisted underwater is connected to the mining vehicle body 10 with the assistance of the underwater robot through the cooperation of the docking member 210 and the mounting portion 100. This enables the timely replacement of the worn front shovel body 200 underwater, greatly optimizing the replacement method of the front shovel body 200 and making it more convenient.

[0041] like Figure 1 、 Figure 2 、 Figure 3 As shown, the mounting portion 100 of this embodiment specifically includes an inserting port 110 and a locking hole 120. The locking hole 120 may be located in front of the inserting port 110. The docking member 210 specifically includes an inserting block 220 and a locking rod 230. The inserting block 220 is located at the rear end of the front shovel body 200, and the locking rod 230 is inserted into the front shovel body 200 and located at the front end of the inserting block 220. The inserting block 220 is inserted into the inserting port 110 and inserted into the locking hole 120 through the locking rod 230, thereby connecting the front shovel body 200 to the mining vehicle body 10. During the detachable assembly, the front shovel body 200 is hoisted, and with the assistance of the underwater robot, the plug block 220 is placed in the plug interface 110, and then the corresponding position of the front shovel body 200 is aligned with the lock hole 120, so that the locking rod 230 is inserted into the lock hole 120 by the underwater robot. In this way, the plug block 220 is docked with the plug interface 110, so that the front shovel body 200 is limited on the mining vehicle body 10 in the up and down directions, and the locking rod 230 is matched with the lock hole 120, so that the front shovel body 200 is limited on the mining vehicle body 10 in the front and back directions and the left and right directions.

[0042] like Figure 1 、 Figure 3 、 Figure 4As shown, the plug port 110 of this embodiment specifically includes a guide port 111 and a connection port 112. The guide port 111 is vertically disposed on the mining vehicle body 10, and the connection port 112 extends in the front-to-back direction and is connected to the lower end of the guide port 111. The plug block 220 includes a connecting arm 221 and a retaining block 222. The connecting arm 221 is connected to the front shovel body 200 and extends downward, while the retaining block 222 is connected to the lower end of the connecting arm 221 and extends rearward. The retaining block 222 changes direction through the connecting arm 221 and is connected to the front shovel body 200. When the plug-in block 220 is assembled with the plug-in interface 110, the hoisted front shovel body 200 is lowered, and the positioning block 222 moves downward or obliquely downward through the guide port 111. After reaching the bottom of the guide port 111, the front shovel body 200 is pushed backward by the underwater robot, so that the positioning block 222 moves backward and enters the connecting port 112 and is stuck in the connecting port 112. Due to the limiting effect of the upper and lower inner walls of the connecting port 112, the plug-in block 220 is inserted into the plug-in interface 110 and is limited in the upper and lower directions.

[0043] like Figure 1 、 Figure 3 、 Figure 4 As shown, the mounting portion 100 of this embodiment includes a mounting block 130 located at the front end of the guide opening 111. The locking hole 120 is opened in the mounting block 130 along the vertical direction. The connecting arm 221 forms an installation space 240 between the front shovel body 200. When the hoisted front shovel body 200 is lowered, the installation space 240 is placed on the mounting block 130. The installation space 240 is larger than the mounting block 130 in the front-to-back direction, so that the front shovel body 200 can be pushed backward. The locking rod 230 is movably arranged on the front shovel body 200 above the installation space 240. When the locking block 222 moves backward and snaps into the connecting opening 112, the locking rod 230 on the front shovel body 200 is aligned with the locking hole 120 below, and the locking rod 230 is inserted downward, connecting the front shovel body 200 to the mounting block 130 like a pin. In this embodiment, multiple locking holes 120 can be arranged at intervals in the left and right directions, and correspondingly multiple locking rods 230 are provided on the front shovel body 200 to limit the front shovel body 200 on the mining vehicle body 10 in the front-to-back direction and the left-to-right direction.

[0044] like Figure 4 、 Figure 5As shown, further, the front side surface of the guide opening 111 of this embodiment is tilted to form an inclined guide surface 113, and the inclined guide surface 113 is tilted toward the rear along the direction from top to bottom. The lower inner wall of the guide opening 111 is set as the inclined guide surface 113. When the shovel body 200 is lowered by hoisting, the blocking block 222 first contacts the inclined guide surface 113. Under the guiding action, the blocking block 222 moves obliquely downward and reaches the bottom of the guide opening 111 and faces the front end opening of the connecting port 112. In this way, accurate alignment with the connecting port 112 can be achieved. In addition, since the upper end of the inclined guide surface 113 will expand the opening of the entire guide opening 111, it is also more conducive to the blocking block 222 entering the plug port 110 from the guide opening 111, and the assembly process is more convenient.

[0045] like Figure 3 、 Figure 4 、 Figure 5 As shown, further, the connecting arm 221 of this embodiment is tilted and tilted backward from top to bottom. The tilted connecting arm 221 allows a certain amount of clearance between the connecting arm 221 and the inner wall of the guide opening 111 when the blocking block 222 enters and exits the connection port 112. In this way, during the disassembly of the underwater robot, after the front shovel body 200 is pulled out to the opening position of the connection port 112, the connecting arm 221 can be tilted under the action of an external crane, thereby making it easier to remove the blocking block 222 from the guide opening 111. This makes the disassembly process easier. To facilitate the lifting of the external crane, the front shovel body 200 is also provided with a lifting ring and other structural parts that facilitate lifting.

[0046] like Figure 3 、 Figure 4 、 Figure 5 As shown, further, a first drain hole 114 is provided in the connection port 112 of this embodiment, and the first drain hole 114 extends to the outside of the mining vehicle body 10. Typically, the left and right sides of the plug-in port 110 are sealed by ribs, and during the insertion of the retaining block 222 into the connection port 112, seawater inside the connection port 112 can be discharged through the first drain hole 114, thereby preventing the seawater from being squeezed into the connection port 112 and causing the retaining block 222 to be unable to be inserted into the connection port 112. In this embodiment, the first drain hole 114 is located within the connection port 112 and on the rear side wall of the connection port 112, placing the first drain hole 114 at the rearmost side of the connection port 112. This facilitates the drainage of seawater from the connection port 112 and avoids interference with the assembly process of the retaining block 222 and the connection port 112.

[0047] like Figure 3 、 Figure 4 、 Figure 5As shown, in this embodiment, the locking rod 230 is further provided with a water flow through hole 231 along the axial direction. The water flow through hole 231 extends vertically through the entire locking rod 230. When the locking rod 230 is inserted into the lock hole 120, this is to balance the water pressure inside and outside the lock hole 120, thereby preventing the locking rod 230 from being unable to be inserted into or removed from the lock hole 120.

[0048] In addition, a drainage hole may also be provided at the bottom of the lock hole 120 so that drainage can be performed when the lock rod 230 is inserted into the lock hole 120 .

[0049] like Figure 3 、 Figure 4 、 Figure 5 As shown, the locking lever 230 of this embodiment primarily comprises a lever body 232 and a lifting portion 233. The lever body 232 is movably mounted on the front shovel body 200 in the vertical direction. The lifting portion 233 is mounted on the lever body 232. Rotating the lever body 232 causes the lifting portion 233 to rotate by a predetermined angle, thereby securing the lever body 232 at a predetermined height after it has been released from the locking hole 120. The lever body 232 can be inserted downward into the locking hole 120 below, achieving a fixed position. During disassembly of the front shovel body 200, the underwater robot pulls the lever body 232 upward to release the lower end of the lever body 232 from the locking hole 120. The lever body 232 is then rotated, causing the lifting portion to rotate by a predetermined angle and then be secured to the front shovel body 200. This prevents the lever body 232 from falling, allowing the lever body 232 to remain stably released from the locking hole 120. The underwater robot can then release the locking lever 230 to perform other operations.

[0050] Furthermore, the lifting portion 233 of this embodiment includes a protruding rod connected to the side wall of the rod body 232. A sliding groove 234 is formed on the side wall of the through hole of the front shovel body 200 in the vertical direction. The protruding rod slides in the sliding groove 234. When the protruding rod slides out of the upper end of the sliding groove 234 and the rod body 232 is twisted to rotate the protruding rod by a predetermined angle, the rod body 232 is fixed at a predetermined height.

[0051] like Figure 3 、 Figure 4 、 Figure 5 As shown, in addition, in order to prevent the locking rod 230 from falling off the front shovel body 200, the rod body 232 can be set to multiple sections with different diameters. For example, the diameter of the middle section of the rod body 232 is smaller than the diameter of the lower end section, and the lower end section of the rod body 232 is used to cooperate with the locking hole 120 for positioning, and the middle section matches the middle through hole in the front shovel body 200, so that the middle section can move up and down in the front shovel body 200, while the lower end section is blocked by the middle through hole of the front shovel body 200 and cannot be pulled out from the front shovel body 200. In addition, countersunk holes are provided at both ends of the middle through hole to facilitate cooperation with the locking hole 120.

[0052] Example 2

[0053] This embodiment provides an underwater mining vehicle, which includes a mining vehicle body 10 and the replaceable front shovel structure as described above.

[0054] In summary, the present application provides a replaceable front shovel structure and an underwater mining vehicle. When the front shovel body 200 needs to be replaced, the docking piece 210 and the mounting portion 100 are separated by an underwater robot, so that the front shovel body 200 is separated from the mining vehicle body 10. The new front shovel body 200 hoisted underwater is connected to the mining vehicle body 10 with the assistance of the underwater robot through the cooperation between the docking piece 210 and the mounting portion 100, thereby realizing timely replacement of the worn front shovel body 200 underwater, greatly optimizing the replacement method of the front shovel body 200, and making the replacement of the front shovel body 200 more convenient.
