Description

Technical Field

[0001] This invention relates to the technical field of mining tunneling equipment, and specifically to a mine mining tunneling equipment and method for screening ore. Background Technology

[0002] In the process of mining, it is necessary to open shafts and tunnels in underground ore deposits to extract minerals. The extraction of minerals can be completed through ore deposit development, ore block preparation, cutting, and recovery. Due to the limited space inside the mine, it is also necessary to transport the minerals out of the mine during the mining process.

[0003] Chinese utility model patent CN221086250U discloses a coal mining and tunneling equipment with a screening mechanism, belonging to the field of coal mining technology. It includes a tunneling shovel with a screening mechanism. The screening mechanism includes a fixed frame installed behind the tunneling shovel, a conveyor belt mounted on the fixed frame, and rotating rollers arranged in three groups on the conveyor belt. Coal ore first enters the screening mechanism through the tunneling shovel. Under the action of the conveyor belt, the rotating rollers rotate, transmitting the coal ore. Gaps exist between the rotating rollers, and some coal ore particles smaller than these gaps fall into the first, second, and third sorting hoppers, thus achieving the purpose of classifying and screening the coal ore.

[0004] The aforementioned tunneling equipment can only excavate ore fragments on the surface and cannot mine or screen more solid and larger ore in the mine. Therefore, existing tunneling equipment is difficult to excavate more solid ore on the mine sidewalls. Summary of the Invention

[0016] This setup enables the collection of ore into a screening mechanism.

[0022] Preferably, the main beam is provided with a spring plate, both ends of which are fixedly connected to the main beam. The spring plate is rotatably connected to a support shaft, and the support shaft is fixedly connected to a support wheel.

[0023] This configuration improves the stability of the main beam.

[0030] 2. The lateral drive component drives the swing frame to move laterally, which in turn drives the first and second tunneling wheels to move laterally, so that the first and second tunneling wheels can scrape away the ore in front of the first and second support frames during the lateral movement, preventing the first and second support frames from being stuck by the ore in front of them.

[0031] 3. The first support frame and the second support frame are staggered to prevent the ore in front of the first support frame and the second support frame from becoming a whole, reducing the integrity of the ore in the mine, thus making it easier to separate the ore into fragments, and making it easier for the first tunneling wheel and the second tunneling wheel to scrape the ore off.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments. However, the scope of protection of this invention is not limited to the specific embodiments described below.

[0039] refer to Figure 1-4 A mine tunneling device for screening ore includes a main beam 10, a tunneling mechanism 30, a collection mechanism 60, and a screening mechanism 70. The tunneling mechanism 30, the collection mechanism 60, and the screening mechanism 70 are mounted on the main beam 10 and arranged sequentially along the length of the main beam 10. The tunneling mechanism 30 is positioned in front of the collection mechanism 60, and the screening mechanism 70 is positioned behind the collection mechanism 60.

[0040] The main beam 10 includes a main beam 11, a secondary beam 12, and two connecting plates 13. The two connecting plates 13 are parallel to each other and are fixedly connected to the main beam 11 and the secondary beam 12, respectively. The connecting plates 13 are vertically arranged, while the main beam 11 and the secondary beam 12 extend horizontally. A support rod 14 is provided between the main beam 11 and the secondary beam 12, and the support rod 14 is fixedly connected to the main beam 11, the secondary beam 12, and the connecting plates 13, respectively. The main beam 11 and the secondary beam 12 support each other through the support rod 14, improving the structural stability of the main beam 11 and the secondary beam 12. The support rod 14, the main beam 11, and the secondary beam 12 provide support forces to the connecting plates 13 at different positions, thereby improving the structural stability of the connecting plates 13 and achieving the advantage of high structural strength for the main beam 10.

[0041] The main beam 11 is equipped with a spring plate 21, with both ends of the spring plate 21 fixedly connected to the main beam 11. A support shaft 22 is rotatably connected to the spring plate 21, and a support wheel 23 is fixedly connected to the support shaft 22. The support wheel 23 rolls on the ground, providing support force to the main beam 11, enabling the main beam 11 to stably support the connecting plate 13 and improving the stability of the main beam 10. A load-bearing seat 24 is installed on the main beam 11, and a pulley 25 is rotatably connected to the load-bearing seat 24. A track 26 is installed below the pulley 25, allowing the pulley 25 to move smoothly on the track 26. The pulley 25 provides support force to the main beam 11 through the load-bearing seat 24, enabling the main beam 11 to stably support the connecting plate 13 and improving the stability of the main beam 10. The load-bearing seat 24 is vertically slidably connected to the main beam 11. The load-bearing seat 24 is threadedly connected to a screw 27, which is rotatably connected to the main beam 11 and threadedly connected to the load-bearing seat 24. The support wheel 23 is located at one end of the main beam 11 near the tunneling mechanism 30. When adjusting the tunneling angle, the screw 27 is rotated, causing the main beam 11 to move relative to the load-bearing seat 24. This allows the main beam 11 to adjust its angle around the support wheel 23, thereby causing the main beam 10 and the tunneling mechanism 30 to deflect at different angles, thus enabling the tunneling mechanism 30 to excavate ore in different directions and achieving the function of adjusting the tunneling angle.

[0042] The tunneling mechanism 30 includes a swing frame 31, a first tunneling wheel 41, and a second tunneling wheel 51. A plurality of sliding columns 32 are fixedly connected to the main beam 10. The sliding columns 32 are perpendicular to the main beam 10 and are fixed on and perpendicular to the connecting plate 13. The swing frame 31 is slidably connected to the sliding columns 32. A transverse drive component 33 is provided between the swing frame 31 and the main beam 10. The transverse drive component 33 is a hydraulic cylinder fixedly installed on the connecting plate 13. The output end of the transverse drive component 33 is connected to the swing frame 31. The swing frame 31 is fixedly connected to a first support frame 42 and a second support frame 52. The first support frame 42 is rotatably connected to a first drive shaft 43. The first tunneling wheel 41 is fixedly mounted on the first drive shaft 43. A first drive structure is provided between the first drive shaft 43 and the first support frame 42. The first drive structure includes a first hydraulic motor 44, a first driving gear 45, and a first driven gear 46. The first hydraulic motor 44 is mounted on the first support frame 42. The first driving gear 45 is fixedly connected to the output shaft of the first hydraulic motor 44. The first driven gear 46 is fixedly connected to the first drive shaft 43 and meshes with the first driving gear 45. The first hydraulic motor 44 drives the first drive shaft 43 to rotate through the first driving gear 45 and the first driven gear 46, thereby realizing the function of driving the first drive shaft 43 to rotate.

[0043] The swing frame 31 is fixedly connected to a second support frame 52, and the second support frame 52 is rotatably connected to a second drive shaft 53. The second tunneling wheel 51 is fixedly mounted on the second drive shaft 53. A second drive structure is provided between the second drive shaft 53 and the second support frame 52. The first support frame 42 and the second support frame 52 are staggered in the sliding direction of the swing frame 31. Figure 4 As shown. The second drive structure includes a second hydraulic motor 54, a second drive gear 55, and a second driven gear 56. The second hydraulic motor 54 is mounted on the second support frame 52. The second drive gear 55 is fixedly connected to the output shaft of the second hydraulic motor 54. The second driven gear 56 is fixedly connected to the second drive shaft 53 and meshes with the second drive gear 55. The second hydraulic motor 54 drives the second drive shaft 53 to rotate through the second drive gear 55 and the second driven gear 56, thus realizing the function of driving the second drive shaft 53 to rotate. Multiple protrusions 57 are provided on the circumferential surfaces of both the first tunneling wheel 41 and the second tunneling wheel 51. The protrusions 57 improve the efficiency of the first tunneling wheel 41 and the second tunneling wheel 51 in scraping off ore.

[0044] The collection mechanism 60 includes a collection conveyor belt 61, guide wheels 62, drive wheels 63, and a bucket 64. Guide wheels 62 and drive wheels 63 are rotatably connected to the connecting plate 13. The collection conveyor belt 61 is wound around the guide wheels 62 and drive wheels 63. The bucket 64 is fixedly connected to the lower end of the connecting plate 13 and is located between the collection conveyor belt 61 and the first tunneling wheel 41. During the forward movement of the crossbeam, the bucket 64 moves with the crossbeam and scoops the ore onto the collection conveyor belt 61. The drive wheel 63 drives the collection conveyor belt 61 to rotate, moving the ore on the dismantling conveyor belt above the filter plate 76. Then, the collection conveyor belt 61 rotates back towards the bucket 64, and the ore, losing the support of the collection conveyor belt 61, falls downwards onto the filter plate 76, thus realizing the function of collecting the ore into the screening mechanism 70.

[0045] The screening mechanism 70 includes a mounting plate 71, a funnel 72, a conveying pipe 73, a crusher 74, and an ore conveyor belt 75. The mounting plate 71 is fixedly mounted on the main beam 11. The funnel 72 is fixedly mounted on the connecting plate 13. An inclined filter plate 76 is fixedly connected to the upper end of the funnel 72, and the lower end of the funnel 72 is connected to the conveying pipe 73 fixedly mounted on the mounting plate 71. The crusher 74 is fixedly connected to the main beam 11 and located below the filter plate 76. The ore conveyor belt 75 is located at the output end of the crusher 74 and is rotatably mounted on the secondary beam 12. Smaller particles of silt on the filter plate 76 can pass through the filter plate 76 and enter the funnel 72. The silt in the funnel 72 is discharged through the conveying pipe 73. Wider ore rolls down the filter plate 76 onto the crusher 74. The crusher 74 crushes the ore and discharges it onto the ore conveyor belt 75, driving the ore conveyor belt 75 to rotate on the secondary beam 12, thereby moving the ore and achieving ore screening and sorting. A water inlet pipe 77 is fixedly installed on the secondary beam 12, and the water inlet pipe 77 is connected to a water spray pipe 78 located above the filter plate 76. The water inlet pipe 77 is connected to an external water source. Water is injected into the water inlet pipe 77, and the water in the water inlet pipe 77 is sprayed onto the filter plate 76 through the water spray pipe 78. The water washes away the mud and sand on the ore, reducing the mud and sand on the ore and improving the filtration effect.

[0046] A method for mine tunneling in which ore is screened, using the mine tunneling device for screening ore described above.

[0047] The crossbeam is pushed forward, causing the first and second tunneling wheels 41 to contact the ore in the mine. The first drive shaft 43 and the second drive shaft 53 drive the first and second tunneling wheels 41 and 51 to rotate forward, causing the lower ends of the first and second tunneling wheels 41 and 51 to move backward. This allows the rotating first and second tunneling wheels 41 and 51 to scrape off the ore in the mine. There are two first tunneling wheels 41, and the second tunneling wheel 51 is located between the two first tunneling wheels 41. The second tunneling wheel 51 and the two first tunneling wheels 41 are arranged in an inclined direction. The lower ends of the first and second tunneling wheels 41 and 51 rotate towards the collection mechanism 60, thereby enabling the first and second tunneling wheels 41 and 51 to push the ore backward. The first tunneling wheel 41, located below the second tunneling wheel 51, is closer to the collection mechanism 60 than the first tunneling wheel 41 located above the second tunneling wheel 51. This allows the higher-positioned ore to be moved backward and downward by the two first tunneling wheels 41 and the second tunneling wheel 51 onto the bucket 64, facilitating its transfer onto the collection conveyor belt 61 via the bucket 64. The lower first tunneling wheel 41 is positioned behind the upper first tunneling wheel 41, ensuring that ore scraped off by the upper first tunneling wheel 41 falls in front of the lower first tunneling wheel 41, preventing it from hitting the lower first tunneling wheel 41 and the second tunneling wheel 51, thus improving reliability.

[0048] This embodiment has the following advantages:

[0049] The tunneling mechanism 30 excavates ore from the mine shaft at the front end of the main beam 10, causing the ore to fall to the ground. The collection mechanism 60 transports the ore from the ground to the screening mechanism 70, where the ore is screened. This achieves the functions of mining, collecting, and screening ore in the mine shaft, and has the advantage of being able to excavate relatively hard ore in the mine shaft.

[0050] The lateral drive component 33 drives the swing frame 31 to move laterally, which in turn drives the first tunneling wheel 41 and the second tunneling wheel 51 to move laterally. This allows the first tunneling wheel 41 and the second tunneling wheel 51 to scrape away the ore in front of the first support frame 42 and the second support frame 52 during the lateral movement, preventing the first support frame 42 and the second support frame 52 from being stuck by the ore in front of them.

[0051] The first support frame 42 and the second support frame 52 are staggered to prevent the ore in front of the first support frame 42 and the second support frame 52 from becoming a single piece, reducing the integrity of the ore in the mine, and making it easier to separate the ore into fragments, so that the first tunneling wheel 41 and the second tunneling wheel 51 can scrape the ore off.

[0052] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the invention.
