Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model proposes a conveying device for underground tunneling in coal mines, including a base 1, a conveying structure 2, and a tunneling structure 3. The conveying structure 2 is mounted on the base 1, and the tunneling structure 3 is mounted on the base 1. The conveying structure 2 includes a fixed plate 4, a rotating roller 5, a conveyor belt 6, a fixed seat 7, a motor 8, a slide rail 9, a telescopic frame 10, a hydraulic cylinder 11, a second rotating roller 12, a second conveyor belt 13, a second fixed seat 14, and a second motor 15. The fixed plate 4 is fixedly mounted on the left and right sides above the base 1. The rotating roller 5 is rotatably mounted on the fixed plate 4. The conveyor belt 6 is rotatably mounted on the front and rear sets of rotating rollers 5. The fixed seat 7 is fixedly mounted on the outer front end of the fixed plate 4. The motor 8 is fixedly mounted on the fixed seat 7, and the front rotating roller 5 is fixed. The first motor 8 is fixed on the output shaft. The slide rail 9 is located on the inner bottom of the base 1 on both sides. The telescopic frame 10 is slidably located in the slide rail 9 on the base 1. The outer side of the telescopic frame 10 is equipped with a limiting slide roller adapted to the slide rail 9. One end of the hydraulic cylinder 11 is fixed on the bottom of the base 1 and the other end is fixed on the support plate of the telescopic frame 10. The second rotating roller 12 is rotatably located on the telescopic frame 10. The second conveyor belt 13 is rotatably located on the front and rear sets of the second rotating roller 12. The first conveyor belt 6 is located above and behind the second conveyor belt 13. Both the second conveyor belt 13 and the first conveyor belt 6 are made of wear-resistant rubber material. The second conveyor belt 13 and the first conveyor belt 6 are arranged in a parallel structure. The second fixed seat 14 is fixed on the front end of the telescopic frame 10. The second motor 15 is fixed on the second fixed seat 14.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the tunneling structure 3 includes a support base 16, a tunneling machine 17, and a discharge pipe 18.

The discharge pipe 18 is located above the rear end of the conveyor belt 6.
[0021] In practical use, a conveyor vehicle is used to push the base 1 forward. Then, the tunneling machine 17 is controlled to rotate forward to excavate coal. The coal is discharged through the discharge pipe 18 onto the conveyor belt 6. Then, the motor 8 is controlled to drive the front rotating roller 5 to rotate, thereby driving the conveyor belt 6 to rotate. The conveyor belt 6 rotates cyclically on the front and rear rotating rollers 15, thus conveying the coal onto the second conveyor belt 13. At the same time, the motor 15 is started to drive the front rotating roller 12 to rotate, thereby... The end rotating roller 12 drives the conveyor belt 13 to rotate, so the conveyor belt 13 rotates cyclically on the front and rear rotating rollers 12, thus pushing the coal blocks forward. Then, the hydraulic cylinder 11 controls the telescopic frame 10 to slide back and forth in the slide rail 9 on the base 1 to adjust the front end of the conveyor belt 13 so that the front end of the conveyor belt 13 is above the bottom small train car, filling the small train car in one go, realizing rapid loading and improving excavation efficiency. The above is the entire process of using the conveyor device for underground tunneling in coal mines.
