[0040] The beam 10 includes a main beam 11, a sub-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 sub-beam 12, respectively. The connecting plates 13 are arranged vertically. The main beam 11 and the sub-beam 12 extend in the horizontal direction. A support rod 14 is arranged between the main beam 11 and the sub-beam 12. The support rod 14 is fixedly connected to the main beam 11, the sub-beam 12 and the connecting plates 13, respectively. The main beam 11 and the sub-beam 12 support each other through the support rod 14, thereby improving the structural stability of the main beam 11 and the sub-beam 12. The support rod 14, the main beam 11 and the sub-beam 12 provide supporting force to the connecting plates 13 at different positions, thereby improving the structural stability of the connecting plates 13 and achieving the advantage of higher structural strength of the beam 10.

[0041] The main beam 11 is provided with a spring plate 21, and both ends of the spring plate 21 are fixedly connected to the main beam 11, and the spring plate 21 is rotatably connected to a support shaft 22, and the support shaft 22 is fixedly connected to a support wheel 23. The support wheel 23 rolls on the ground, so that the support wheel 23 can provide support force to the main beam 11, so that the main beam 11 can stably support the connecting plate 13, and improve the stability of the beam 10. The main beam 11 is installed with a bearing seat 24, and the bearing seat 24 is rotatably connected to a pulley 25. A track 26 is installed under the pulley 25, so that the pulley 25 moves smoothly on the track 26. The pulley 25 provides support force to the main beam 11 through the bearing seat 24, so that the main beam 11 can stably support the connecting plate 13, and improve the stability of the beam 10. The bearing seat 24 is vertically slidably connected to the main beam 11, and the bearing seat 24 is threadedly connected to the screw 27, which is rotatably connected to the main beam 11 and threadedly connected to the bearing seat 24. The support wheel 23 is located at one end of the main beam 11 close to the excavation mechanism 30. When the excavation angle is to be adjusted, the screw 27 is rotated to move the main beam 11 relative to the bearing seat 24, so that the main beam 11 adjusts its angle around the support wheel 23, thereby deflecting the beam 10 and the excavation mechanism 30, and then the excavation mechanism 30 excavates ore in different directions, thereby achieving the function of adjusting the excavation angle.

[0042] The excavation mechanism 30 includes a swing frame 31, a first excavation wheel 41 and a second excavation wheel 51. The beam 10 is fixedly connected to a plurality of sliding columns 32. The sliding columns 32 are perpendicular to the beam 10. The sliding columns 32 are fixed on the connecting plate 13 and are perpendicular to the connecting plate 13. The swing frame 31 is slidably connected to the sliding columns 32. A transverse driving member 33 is provided between the swing frame 31 and the beam 10. The transverse driving member 33 is a hydraulic cylinder fixedly mounted on the connecting plate 13. The output end of the transverse driving member 33 is connected to the swing frame 31. The swing frame 31 is fixedly connected to the first support frame 42 and the second support frame 52, the first support frame 42 is rotatably connected to the first drive shaft 43, the first excavation 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 comprises 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 the second support frame 52, the second support frame 52 is rotatably connected to the second drive shaft 53, the second excavation 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, and the first support frame 42 and the second support frame 52 are staggered in the sliding direction of the swing frame 31, as shown in FIG. Figure 4 As shown. The second driving structure includes a second hydraulic motor 54, a second driving gear 55 and a second driven gear 56. The second hydraulic motor 54 is mounted on the second support frame 52. The second driving 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 driving shaft 53 and meshes with the second driving gear 55. The second hydraulic motor 54 drives the second driving shaft 53 to rotate through the second driving gear 55 and the second driven gear 56, thereby realizing the function of driving the second driving shaft 53 to rotate. A plurality of protrusions 57 are provided on the circumferential surfaces of the first excavation wheel 41 and the second excavation wheel 51. The arrangement of the protrusions 57 improves the efficiency of the first excavation wheel 41 and the second excavation wheel 51 in scraping off ore.

[0044] The collection mechanism 60 includes a collection conveyor belt 61, a guide wheel 62, a driving wheel 63 and a bucket 64. The guide wheel 62 and the driving wheel 63 are both rotatably connected to the connecting plate 13. The collection conveyor belt 61 is wound around the guide wheel 62 and the driving wheel 63. The bucket 64 is fixedly connected to the lower end of the connecting plate 13, and the bucket 64 is located between the collection conveyor belt 61 and the first excavation wheel 41. In the process of the crossbeam moving forward, the bucket 64 moves with the crossbeam and shovels the ore onto the collection conveyor belt 61. The driving wheel 63 drives the collection conveyor belt 61 to rotate, so that the ore on the disassembly conveyor belt moves to the top of the filter plate 76, and then the collection conveyor belt 61 rotates toward the bucket 64. The ore loses the support of the collection conveyor belt 61 and falls downward onto the filter plate 76, thereby realizing the function of collecting the ore to 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, the upper end of the funnel 72 is fixedly connected with an inclined filter plate 76, the lower end of the funnel 72 is connected with a conveying pipe 73 fixedly mounted on the mounting plate 71, the crusher 74 is fixedly connected to the main beam 11 and is located below the filter plate 76, the ore conveyor belt 75 is located at the output end of the crusher 74, and the ore conveyor belt 75 is rotatably mounted on the sub-beam 12. Smaller sediment on the filter plate 76 can pass through the filter plate 76 and enter the funnel 72, and the sediment in the funnel 72 is discharged through the conveying pipe 73. The ore with a larger width rolls down on the filter plate 76 to the crusher 74. The crusher 74 crushes the ore and discharges it to the ore conveyor belt 75, driving the ore conveyor belt 75 to rotate on the auxiliary beam 12, thereby driving the ore conveyor belt 75 to move, thereby realizing the screening and classification transportation of the ore. The auxiliary beam 12 is fixedly installed with a water inlet pipe 77, and the water inlet pipe 77 is connected to a water spray pipe 78 located above the filter plate 76, and 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 the sediment on the ore, reduces the sediment on the ore, and plays a role in improving the filtering effect.

[0046] A mine mining and excavation method for screening ore adopts the mine mining and excavation device for screening ore mentioned above.

[0047] The crossbeam is pushed forward to drive the first excavation wheel 41 and the second excavation wheel 51 to contact the ore in the mine, and the first drive shaft 43 and the second drive shaft 53 drive the first excavation wheel 41 and the second excavation wheel 51 to rotate forward, so that the lower ends of the first excavation wheel 41 and the second excavation wheel 51 move backward, so that the ore in the mine can be scraped off by the rotating first excavation wheel 41 and the second excavation wheel 51. Two first excavation wheels 41 are provided, and the second excavation wheel 51 is between the two first excavation wheels 41. The second excavation wheel 51 and the two first excavation wheels 41 are arranged in an inclined direction, and the lower ends of the first excavation wheel 41 and the second excavation wheel 51 rotate in a direction close to the collection mechanism 60, so that the first excavation wheel 41 and the second excavation wheel 51 can push the ore backward. The first excavation wheel 41 located below the second excavation wheel 51 is closer to the collection mechanism 60 than the first excavation wheel 41 located above the second excavation wheel 51, so that the ore at a higher position can be moved backward and downward to the bucket 64 under the push of the two first excavation wheels 41 and the second excavation wheel 51, so that the ore can be pushed onto the collection conveyor belt 61 by the bucket 64. The lower first excavation wheel 41 is located at the rear side of the upper first excavation wheel 41, so that the ore scraped off by the upper first excavation wheel 41 falls in front of the lower first excavation wheel 41, preventing the ore scraped off by the upper first excavation wheel 41 from hitting the lower first excavation wheel 41 and the second excavation wheel 51, thereby improving reliability.

[0048] This embodiment has the following advantages:

[0049] The excavation mechanism 30 excavates the ore in the mine at the front end of the beam 10, causing the ore to fall to the ground, and transports the ore on the ground to the screening mechanism 70 through the collecting mechanism 60. The ore is screened by the screening mechanism 70, thereby realizing the functions of mining, collecting and screening the ore in the mine, achieving the advantage of being able to excavate the relatively solid ore in the mine.

[0050] The transverse driving member 33 drives the swing frame 31 to move transversely, and drives the first excavation wheel 41 and the second excavation wheel 51 to move transversely, so that the first excavation wheel 41 and the second excavation wheel 51 can scrape the ore in front of the first support frame 42 and the second support frame 52 during the transverse movement, and prevent 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 ores in front of the first support frame 42 and the second support frame 52 from being connected together, thereby reducing the integrity of the ore in the mine, making it easier to separate the ore into fragments, and facilitating the first excavation wheel 41 and the second excavation wheel 51 to scrape the ore.
