[0015] The mining transport vehicle provided in this embodiment can achieve the following technical effects:

[0016] The mining transport vehicle disclosed herein includes a chassis, a cab, a hopper, and a pusher. The chassis is used to move the entire vehicle. The cab is located at the front of the vehicle and is used by the driver to operate it. The hopper is located at the rear of the cab and is used to carry ore. The pusher is located at the front of the chassis and protrudes from the cab. The pusher is used to clear obstacles from the road surface during movement.

[0017] The pusher includes a main body, an auxiliary shovel, a movable mechanism, and a reset mechanism. The main body is connected to the chassis. The auxiliary shovel is located below the main body. The movable mechanism is located on the main body, and the auxiliary shovel is rotatably connected to it, allowing the auxiliary shovel to switch between a pushing position and a clearance position relative to the main body. The movable end of the reset mechanism is connected to the movable mechanism, and the other end is connected to the main body. The reset mechanism drives the auxiliary shovel to reset from the clearance position to the pushing position.

[0018] The mining transport vehicle disclosed herein, by means of a pusher, enables the clearing of road obstacles during vehicle movement. Furthermore, the pusher comprises a main body and an auxiliary body. The main body plays a primary role in clearing road obstacles, while the auxiliary body, under the action of a movable mechanism, can rotate relative to the main body. Thus, when there are hard rocks or other obstacles on the road, the obstacle exerts an upward reaction force on the auxiliary body. Since the auxiliary body is rotatably connected to the main body via the movable mechanism, this upward force drives the auxiliary body to rotate from a pushing position to a clearance position, meaning the entire auxiliary body lifts up, leaves the ground, and passes over the obstacle. During this process, the reset mechanism is further compressed, storing energy. As the vehicle continues forward, the auxiliary body has completely passed the obstacle, and there are no longer any supports or obstructions below it. The compressed reset mechanism, in order to return to its original state, generates a downward thrust, which acts on the movable mechanism, causing the auxiliary body to rotate downward, thus resetting it from the clearance position to the pushing position.

[0019] In addition, by installing a universal protective device on the side of the connecting beam facing the auxiliary shovel plate, the universal protective device plays a role in buffering and blocking the connecting beam, preventing the auxiliary shovel plate from hitting the connecting beam during rotation relative to the shovel plate body.

[0020] Thus, the mining transport vehicle provided in this disclosure can not only clear obstacles on the road surface, but also automatically avoid obstacles, improving the vehicle's passability, protection, and operational efficiency in complex road environments.

[0047] In some embodiments, combined with Figure 1 and Figure 2 As shown, a mining transport vehicle 1 is provided, including a chassis 10, a driver's cab 20, a hopper 30, and a pusher 40. The driver's cab 20, the hopper 30, and the pusher 40 are all mounted on the chassis 10. The pusher 40 is located at the front of the chassis 10 and is used to clear road obstacles for the chassis 10 during travel. Figures 5 to 8 As shown, the pusher 40 includes a shovel body 41 connected to the chassis 10; an auxiliary shovel 43 disposed on the shovel body 41 and located below it; a movable mechanism 44 disposed on the shovel body 41, the auxiliary shovel 43 being rotatably connected to the movable mechanism 44 so that the auxiliary shovel 43 can switch between a pushing position and a clearance position relative to the shovel body 41; and a reset mechanism 45, the movable end of which is connected to the movable mechanism 44, and the other end of which is connected to the shovel body 41. The reset mechanism 45 is used to drive the auxiliary shovel 43 to reset from the clearance position to the pushing position.

[0048] The mining transport vehicle 1 disclosed herein includes a chassis 10, a driver's cab 20, a hopper 30, and a pusher 40. The chassis 10 is used to move the entire vehicle. The driver's cab 20 is located at the front of the vehicle and is used by the driver to operate the vehicle. The hopper 30 is located at the rear of the driver's cab 20 and is used to carry ore. The pusher 40 is located at the front of the chassis 10 and protrudes from the driver's cab 20. The pusher 40 is used to clear obstacles from the road surface during movement.

[0049] Combination Figures 5 to 8 As shown, the pusher 40 includes a shovel body 41, an auxiliary shovel 43, a movable mechanism 44, and a reset mechanism 45. The shovel body 41 is connected to the chassis 10. The auxiliary shovel 43 is disposed on the shovel body 41 and located below it. The movable mechanism 44 is disposed on the shovel body 41, and the auxiliary shovel 43 is rotatably connected to the movable mechanism 44, so that the auxiliary shovel 43 can switch between a pushing position and a clearance position relative to the shovel body 41. The movable end of the reset mechanism 45 is connected to the movable mechanism 44, and the other end of the reset mechanism 45 is connected to the shovel body 41. The reset mechanism 45 is used to drive the auxiliary shovel 43 to reset from the clearance position to the pushing position.

[0050] The mining transport vehicle 1 disclosed herein, by means of a pusher 40, can clear road obstacles during vehicle operation. Furthermore, the pusher 40 includes a main shovel plate 41 and an auxiliary shovel plate 43. The main shovel plate 41 plays a primary role in clearing road obstacles, while the auxiliary shovel plate 43, under the action of a movable mechanism 44, can rotate relative to the main shovel plate 41. Thus, when there are hard rocks or other obstacles on the road surface, the obstacles exert an upward reaction force on the auxiliary shovel plate 43. Since the auxiliary shovel plate 43 is rotatably connected to the main shovel plate 41 via the movable mechanism 44, the upward force drives the auxiliary shovel plate 43 to rotate from the pushing position to the avoidance position, i.e., the entire auxiliary shovel plate 43 will lift upward, leave the ground, and pass over the obstacle. During this process, the reset mechanism 45 is further compressed, storing energy. As the vehicle continues to move forward, the auxiliary shovel 43 has completely passed the obstacle, and there are no longer any supports or obstructions below it. The compressed reset mechanism 45 will generate a downward thrust to restore its original state, which will act on the movable mechanism 44 and drive the auxiliary shovel 43 to rotate downward, that is, the auxiliary shovel 43 will be reset from the avoidance position to the pushing position.

[0051] Thus, the mining transport vehicle 1 provided in this disclosure can not only clear obstacles on the road surface, but also automatically avoid obstacles, thereby improving the vehicle's passability, protection, and operational efficiency in complex road environments.

[0052] Optionally, the mining transport vehicle 1 also includes: tracked wheels, which are mounted on the chassis 10 and used to move the entire vehicle.

[0053] Optionally, combined Figure 5 , Figure 7 and Figure 8As shown, the movable mechanism 44 includes: a mounting base 441, which is disposed on the back side of the shovel plate body 41; a rotating base 442, which is rotatably connected to the mounting base 441, and the rotating base 442 is provided with a connecting seat, the movable end of the reset mechanism 45 being connected to the connecting seat; and an arc-shaped connecting rod 443, one end of which is fixedly connected to the auxiliary shovel plate 43, and the other end of which is connected to the rotating base 442.

[0054] In this embodiment, the front side of the shovel body 41 is used to push obstacles, and a mounting base 441 is provided on the back side of the shovel body 41 opposite to the front side. A rotating base 442 is rotatably connected to the mounting base 441, and an arc-shaped connecting rod 443 is used to connect the auxiliary shovel 43 and the rotating base 442. This allows the auxiliary shovel 43 to rotate relative to the shovel body 41 when it encounters an obstacle that the pusher 40 cannot push, thus achieving automatic obstacle avoidance. The arc-shaped connecting rod 443 ensures that the movement trajectory of the auxiliary shovel 43 is smooth and controlled when it rotates upwards.

[0055] As the mining vehicle 1 moves forward, the auxiliary shovel 43 of the pusher 40 first contacts an obstacle protruding from the road surface. The obstacle exerts an upward reaction force on the auxiliary shovel 43. Since the auxiliary shovel 43 is fixedly connected to the rotating seat 442 via the arc-shaped connecting rod 443, this upward force is transmitted to the rotating seat 442. The rotating seat 442 begins to rotate upward relative to the mounting base 441. As the rotating seat 442 rotates, the entire auxiliary shovel 43 is lifted upward, leaving the ground and passing over the obstacle. At this time, the auxiliary shovel 43 switches from the pushing position to the avoidance position. During this process, the reset mechanism 45 is further compressed, storing energy. Because the auxiliary shovel 43 is lifted upward, rather than pushed forward in a hard collision, it does not have a violent rigid collision with the obstacle, thus protecting the pusher 40 itself and the vehicle's chassis 10.

[0056] The vehicle continues forward, and the auxiliary shovel 43 has completely passed the obstacle, with no further support or obstruction beneath it. The compressed reset mechanism 45, returning to its original state, generates a downward thrust acting on the rotating seat 442. This downward force, through the rotating seat 442 and the arc-shaped connecting rod 443, causes the auxiliary shovel 43 to rotate downwards around the connecting pin between the rotating seat 442 and the mounting base 441. The auxiliary shovel 43 smoothly returns to the ground, resuming its pushing position and continuing its function of cleaning and leveling the road surface.

[0057] Optionally, combined Figure 5 , Figure 7 and Figure 8As shown, the pusher 40 also includes: a mounting bracket 42, which is disposed on the back side of the shovel plate body 41 and above the mounting base 441; the other end of the reset mechanism 45 is connected to the shovel plate body 41 through the mounting bracket 42.

[0058] In this embodiment, by providing a mounting bracket 42 on the back side of the shovel plate body 41, the other end of the reset mechanism 45 is fixed by the mounting bracket 42, thereby improving the stability of the reset mechanism 45.

[0059] Optionally, combined Figure 5 , Figure 7 and Figure 8 As shown, the reset mechanism 45 includes: a first seat 46 connected to the connecting seat; a second seat 47 disposed on the mounting bracket 42; a shaft 48, one end disposed on the first seat 46 and the other end passing through the second seat 47, and the shaft 48 is slidable relative to the second seat 47; and a spring assembly 49 sleeved on the shaft 48 and located between the first seat 46 and the second seat 47; wherein, when the auxiliary shovel plate 43 is in the pushing position, the spring assembly 49 is preloaded so that the spring assembly is in a semi-compressed state.

[0060] In this embodiment, the first seat 46 is connected to the connecting seat of the rotating seat 442. As the rotating seat 442 rotates, it drives the first seat 46 to move, further compressing the spring assembly 49. Because the spring assembly 49 is preloaded, it is in a semi-compressed state. This semi-compressed state generates a rebound force, which supports the auxiliary shovel plate 43 in the pushing position. As the auxiliary shovel plate 43 rotates relative to the shovel plate body 41, it further compresses the spring assembly 49. Thus, the combination of the preload of the spring assembly 49 and the rebound force generated by compression, when there are no strong obstacles on the roadside, drives the rotating seat 442 to rotate, causing the auxiliary shovel plate 43 to return to the pushing position.

[0061] Optionally, combined Figure 7 As shown, the second seat 47 includes: a first sub-seat 471, including a through hole and a receiving groove located outside the through hole, the through hole being used to install the shaft 48, and the receiving groove being used to install one end of the spring assembly 49; a second sub-seat 474, connected to the mounting bracket 42, the second sub-seat 474 including a through cavity, the through cavity being used to install the shaft 48 and the spring assembly 49, wherein the second sub-seat 474 is located between the first seat 46 and the first sub-seat 471, the first sub-seat 471 and the second sub-seat 474 are connected by bolts 475, the distance between the first sub-seat 471 and the second sub-seat 474 is adjusted by bolts 475 to adjust the preload of the spring assembly 49.

[0062] In this embodiment, the second seat 47 includes a first sub-seat 471, a second sub-seat 474, and a bolt 475. The distance between the first sub-seat 471 and the second sub-seat 474 can be adjusted by adjusting the bolt 475. Since the second sub-seat 474 is connected to the mounting bracket 42, its position is fixed. Adjusting the bolt 475 allows the first sub-seat 471 to move closer to or further away from the second sub-seat 474, thereby adjusting the distance between the second sub-seat 474 and the first seat 474. Because the spring assembly 49 is positioned between the first seat 46 and the second sub-seat 474, the compression state of the spring assembly 49 can be adjusted, thus adjusting the preload after installation. For example, reducing the distance between the first seat 46 and the second sub-seat 474 will compress the spring assembly 49. The compression is inversely proportional to the distance; the smaller the distance, the greater the compression and the greater the preload. The preload of the spring assembly 49 is sufficient to ensure that the auxiliary shovel plate 43 can be firmly pressed into the pushing position when there are no obstacles, preventing accidental operation due to slight bumps when the vehicle is traveling on uneven roads. Therefore, the specific value of the preload can be set according to the specific weight of the pusher 40, and is not limited here.

[0063] In this way, by utilizing the physical properties of the spring, the energy generated during obstacle avoidance is stored and released when needed to complete the reset, ensuring that the pusher 40 can immediately return to working status after the vehicle passes through the obstacle, without affecting continuous operation.

[0064] Optionally, combined Figure 7 As shown, the spring assembly 49 includes: a first spring 491 and a second spring 492, the diameter of the first spring 491 being smaller than the diameter of the second spring 492; the receiving groove includes a first groove 472 and a second groove 473, the first groove 472 communicating with a through hole, the second groove 473 being located outside the first groove 472, one end of the first spring 491 being installed in the first groove 472, and one end of the second spring 492 being installed in the second groove 473.

[0065] In this embodiment, the first spring 491 has a smaller diameter and can absorb high-frequency, small-amplitude vibrations; the second spring 492 has a larger diameter and can withstand greater impact loads. When the two work together, they can cover impact requirements of different intensities and improve the overall buffering effect. The first spring 491 is installed in the first groove 472, which communicates with the through hole, and the second spring 492 is located in the outer second groove 473. This layered design ensures more uniform force transmission during the reset process, avoids failure of a single spring due to excessive deformation, and enhances the reliability of the mechanism's reset. The mining transport vehicle 1 often faces varying loads and impacts. The sleeve structure of the first and second springs 492 can balance the performance requirements of daily operation and extreme working conditions through different stiffness matching, and extend the service life of the components.

[0066] Optionally, combined Figure 7 As shown, the first seat 46 includes: an annular plate 461, which surrounds the periphery of the shaft 48 and forms an annular groove between the shaft 48; the other end of the first spring 491 is disposed in the annular groove; and the other end of the second spring 492 is sleeved on the outer wall of the annular plate 461 and connected to the first seat 46.

[0067] In this embodiment, an annular plate 461 surrounds the shaft 48 to form an annular support structure, which is used to fix the ends of the first spring 491 and the second spring 492, ensuring that the springs are subjected to uniform force and avoiding failure caused by uneven loading. An annular groove is located between the annular plate 461 and the shaft 48, providing installation space for the first spring 491 and realizing the axial positioning of the spring and the transmission of force.

[0068] Optionally, combined Figure 2 and Figure 3 As shown, the mining transport vehicle 1 also includes: a connecting beam 50, one end of which is connected to the traveling chassis 10, and the other end of which is connected to the shovel body 41; a universal protective device 60, which is provided on the connecting beam 50 and located on the side of the connecting beam 50 opposite to the auxiliary shovel 43; wherein, the universal protective device 60 includes: a base 62, which is provided on the connecting beam 50 and has a groove structure; a base 64, which is provided in the groove structure of the base 62; and a universal ball 66, which is provided on the base 64 and located away from the end of the base 62.

[0069] In this embodiment, a universal protective device 60 is provided on the side of the connecting beam 50 facing the auxiliary shovel plate 43. The universal protective device 60 buffers and blocks the connecting beam 50, preventing the auxiliary shovel plate 43 from impacting the connecting beam 50 during rotation relative to the shovel plate body 41. The universal protective device 60 includes a base 64 and a universal ball 66. Because the structure of the universal ball 66 is not restricted by direction, it can buffer and block, thereby preventing the connecting beam 50 from being impacted.

[0070] Optionally, combined Figure 4 As shown, the base 64 includes: an outer ring body 642, which is fitted into a groove structure and has a stepped through hole structure; a fixing seat 644, which is configured to have a stepped boss structure, and the fixing seat 644 is adapted to the stepped through hole to fit the fixing seat 644 into the outer ring body 642; a mounting groove 646, which is disposed on the fixing seat 644 at one end away from the base 62, and a universal ball 66 is disposed in the mounting groove 646; a ball bearing 648, which is disposed in the mounting groove 646 and located between the universal ball 66 and the mounting groove 646; and a limiting block 649, which is disposed in the mounting groove 646 to fit the universal ball 66 into the mounting groove 646.

[0071] In this embodiment, the base 64 includes: an outer ring body 642, a fixed seat 644, a mounting groove 646, a ball bearing 648, and a limiting block 649. By placing the universal ball 66 on the ball bearing 648 and using the limiting block 649 to limit the universal ball 66 relative to the mounting groove 646, adaptability is improved.

[0072] Optionally, the mounting groove 646 is a stepped groove, including a first groove and a second groove, wherein the radial distance of the first groove is less than the radial distance of the second groove; wherein, the first groove is hemispherical, the ball bearing 648 and the universal ball 66 are disposed in the first groove, and the limiting block 649 is disposed in the second groove to lock the universal ball 66.
