[0035] Hydraulic cylinders 905 are rotatably connected to the two edges of the mounting base 903. Hydraulic cylinders 905 drive hydraulic rods 906. Hydraulic rods 906 are slidably connected to the inner surface of hydraulic cylinders 905. Hydraulic rods 906 push connecting seats 907 to move. Connecting seats 907 are rotatably connected to the other side of hydraulic rods 906. Connecting seats 907 drive connecting rods 9012 to move. Connecting rods 9012 are fixedly connected to the other side of connecting seats 907. Connecting rods 9012 drive connecting rods 908 on both sides to move. 2. Connecting rods 908 are fixedly installed on both sides. The connecting rods 908 are used to drive the pressing cylinders 9011 at the edge position to move and press the conveyor belt 4. Positioning seats 909 are bolted to the upper positions on both sides of the connecting rods 908. Positioning seats 909 are used to fix the position of the mounting shaft 9010.

[0036] A tensioning wheel 307 is rotatably mounted on one side of the outer surface of the transmission chain 303. The tensioning wheel 307 is used to tension the transmission chain 303. A positioning frame 306 is rotatably connected to the inner surface of the tensioning wheel 307. The positioning frame 306 is used to fix the position of the tensioning wheel 307. The positioning frame 306 is rotatably connected to the lower end edge of the mounting frame 2. A main shaft 8 is fixedly connected to the other side of the connecting shaft 304. The main shaft 8 is used to drive the drive roller 6 to rotate. The drive roller 6 is snapped onto the outer surface of the main shaft 8. The drive roller 6 is used to drive the conveyor belt 4 to rotate. The inner walls of the mounting frame 2 are located on both sides. An auxiliary shaft 5 is rotatably mounted at the edge position. The auxiliary shaft 5 is used to drive the auxiliary roller 7 to rotate. The auxiliary roller 7 is snapped onto the outer surface of the auxiliary shaft 5.

The conveyor belt 4 is used to transport coal to the bucket wheel excavator.

[0037] Working Principle: The output of the drive motor 301 drives the fixedly connected drive wheel 302 to rotate. The rotation of the drive wheel 302 drives the transmission chain 303 to circulate. The movement of the transmission chain 303 drives the drive wheel 305 to rotate. The main shaft 8, fixedly connected to the other side of the connecting shaft 304, also rotates synchronously. The drive roller 6, which is engaged with the outer surface of the main shaft 8, rotates with the rotation of the main shaft 8. The rotation of the drive roller 6 drives the conveyor belt 4, which is slidably connected to its outer surface, to start moving. The auxiliary roller 7 supports and guides the conveyor belt 4, ensuring that the conveyor belt 4 can stably circulate between the drive roller 6 and the auxiliary roller 7. The position and angle of the tensioning wheel 307 can be adjusted according to the working state of the transmission chain 303, thereby adjusting the tension of the transmission chain 303 and ensuring the stability of the transmission. The hydraulic cylinder 905 is connected to the hydraulic control system through the connecting line 904. When it is necessary to adjust the clamping force of the clamping cylinder 9011 on the conveyor belt 4, the hydraulic control system controls the flow of hydraulic oil inside the hydraulic cylinder 905. The flow of hydraulic oil causes the hydraulic rod 906 to slide around the inner surface of the hydraulic cylinder 905. The other side of the hydraulic rod 906 is rotatably connected to the connecting seat 907, so the extension and retraction of the hydraulic rod 906 will cause the connecting seat 907 to move. The connecting rod 9012, which is fixedly connected to the other side of the connecting seat 907, moves with the movement of the connecting seat 907. Since connecting rods 908 are fixedly installed on both sides of the connecting rod 9012, the connecting rods 908 will also move accordingly. The inner surface of the positioning seat 909, which is bolted to the upper part of both sides of the connecting rod 908, is rotatably connected to the mounting shaft 9010. When the connecting rod 908 moves, the clamping cylinder 9011, which is fixedly installed on the outer surface of the mounting shaft 9010, moves with the movement of the mounting shaft 9010, thereby adjusting the clamping force on the conveyor belt 4.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
