[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0024] according to Figure 1 、 2 As shown in Figures 3, 4, and 5, a coal mine transport and unloading device is proposed in this embodiment, including a frame 1, a belt 3 and two power rollers 4 are provided at the upper end of the frame 1, the two ends of the belt 3 are sleeved on the outside of the two power rollers 4, a waste box 6 is provided under the frame 1, and the waste box 6 is connected to a dust cover 5 fixed to the lower end of the frame 1;
[0025] A brush plate 10 and a cleaning roller 8 are provided on the inner side of the dust cover 5. The cleaning roller 8 is rotatably connected to the dust cover 5. The brush plate 10 is placed above the waste box 6 and directly in front of the cleaning roller 8. The brush plate 10 and the cleaning roller 8 are in contact with the outer wall of the belt 3.
[0026] Belt conveyors are used to transport and unload the ore. As the belt 3 moves, a brush plate 10 beneath it cooperates with a cleaning roller 8 to efficiently clean the surface of the belt 3, effectively removing any residue and ensuring stable material feeding. Because both the brush plate 10 and the cleaning roller 8 are housed within a dust cover 5, any debris generated is collected in a waste bin 6, effectively reducing dust pollution and creating a healthy working environment.
[0027] The dust cover 5 is provided with a first power member for controlling the rotation of the cleaning roller 8 and a second power member for controlling the horizontal shaking of the brush plate 10.
[0028] The first power member controls the cleaning roller 8 to rotate, and the cleaning roller 8 cleans the surface of the belt 3 during rotation. The second power member controls the brush plate 10 to swing left and right, and the brush plate 10 cleans the surface of the belt 3 during swinging.
[0029] About First Powertrain:
[0030] The first power member includes a first motor 9, the mounting end of the first motor 9 is fixedly connected to the outside of the dust cover 5, and the output end of the first motor 9 is fixedly connected to the cleaning roller 8. The rotation of the cleaning roller 8 is controlled by the first motor 9, and no further explanation is given here.
[0031] About the second power component: the second power component includes a fixed seat 12 and a floating block 11. The fixed seat 12 is fixedly connected to the inner side of the dust cover 5. The floating block 11 is fixedly connected to the lower end of the brush plate 10. At least two limit rods 13 are provided between the floating block 11 and the fixed seat 12. One end of the limit rod 13 is fixedly connected to the fixed seat 12, and the other end of the limit rod 13 passes through the floating block 11. The limit rod 13 is slidingly connected to the floating block 11. A spring 14 is provided on the outer sleeve of the limit rod 13. The two ends of the spring 14 are respectively fixedly connected to the fixed seat 12 and the floating block 11. An eccentric wheel component for pushing the floating block 11 toward the fixed seat 12 is provided on the inner side of the dust cover 5.
[0032] When the brush plate 10 is working, the eccentric wheel pushes the floating block 11 toward the fixed seat 12. The floating block 11 slides along the rod of the limit rod 13, the distance between the floating block 11 and the fixed seat 12 decreases, and the spring 14 contracts. When the thrust on the floating block 11 disappears, the floating block 11 returns to its original position under the push of the spring 14, thereby achieving reciprocating control of the brush plate 10.
[0033] It is worth further explaining that the eccentric wheel assembly includes a second motor 16 and an eccentric wheel 17. The eccentric wheel 17 is placed below the brush plate 10. The eccentric wheel 17 is in contact with the floating block 11. The mounting end of the second motor 16 is fixedly connected to the inner side of the dust cover 5. The output end of the second motor 16 is fixedly connected to the eccentric wheel 17. The second motor 16 drives the eccentric wheel 17 to rotate. The axis of the eccentric wheel 17 deviates from the axis of the output shaft of the second motor 16. Therefore, when the eccentric wheel 17 rotates, the edge of the eccentric wheel 17 will continuously push the floating block 11. Under the action of the spring 14, the floating block 11 is always in a state of close contact with the eccentric wheel 17.
[0034] To prevent the floating block 11 from detaching from the limiting rod 13 as it slides along the shaft of the limiting rod 13, in a preferred embodiment, a limiting ring 15 is provided at the end of the limiting rod 13 away from the fixing seat 12. The limiting ring 15 is fixedly connected to the limiting rod 13 and has a diameter larger than the aperture at which the floating block 11 fits into the limiting rod 13. When the floating block 11 is about to be pushed out of the shaft of the limiting rod 13, the limiting ring 15 on the limiting rod 13 will retain the floating block 11 in its position.
[0035] In order to make the brush plate 10 and the cleaning roller 8 fit more closely to the belt 3, in a preferred embodiment, a pressure roller 7 is provided above the dust cover 5. The pressure roller 7 is rotatably connected to the upper end of the frame 1. The pressure roller 7 fits the inner wall of the belt 3, and the brush plate 10 and the cleaning roller 8 are staggered from the pressure roller 7. The pressure roller 7 is arranged between the brush plate 10 and the cleaning roller 8 and staggered from the brush plate 10 and the cleaning roller 8. While not affecting the conveying of the mineral material by the belt 3, the pressure roller 7 presses down the belt 3 to ensure that the outer wall of the belt 3 is in close contact with the brush plate 10 and the cleaning roller 8, thereby improving the cleaning effect of the cleaning roller 8 and the brush plate 10 on the outer wall of the belt 3.
[0036] In addition, a plurality of bases 2 are provided at the lower end of the frame 1, which are fixedly connected to the frame 1, and ribs are fixedly connected between two adjacent bases 2. Reinforcement ribs are provided at the connection between the ribs and the bases 2 to ensure the stable support of the frame 1.
[0037] How this application works:
[0038] Belt conveyors are used to transport and unload the mineral material. When belt 3 is in motion, the first power element controls the rotation of cleaning roller 8, which cleans the surface of belt 3 as it rotates. The second power element controls the left-right oscillation of brush plate 10, which also cleans the surface of belt 3 as it oscillates. The brush plate 10 works in conjunction with the cleaning roller 8 to efficiently clean the surface of belt 3, effectively removing any residue and ensuring stable material feeding. Because both the brush plate 10 and cleaning roller 8 are housed within a dust cover 5, any debris generated is collected in a waste bin 6, effectively reducing dust pollution and creating a healthy working environment.
