[0023] like Figure 1-3 As shown, a belt conveyor includes a frame 9, a front driving roller 1 is provided at the front end of the frame 9, a rear driven roller 7 is provided at the rear end of the frame 9, and a support frame 13 is connected to the rear end of the frame 9. Two parallel beams 17 are provided on both sides of the support frame 13, and a slider 15 is slidably connected between the two beams 17. The two beams 17 are provided with a slideway that can accommodate the sliding of the slider 15, and the slider 15 is provided with a bearing. The rear driven roller 7 has a rotating shaft 14, and the two ends of the rotating shaft 14 are respectively rotatably connected to the bearings on the sliders 15 on both sides. One end of the slider 15 is threadedly connected to a screw 8, and one end of the screw 8 is fixedly connected to the slider 15 by a fastening bolt 16. The other end of the screw 8 passes through the support frame 13 and is threadedly connected to the support frame 13. The position of the rear driven roller 7 can be adjusted by the screw 8, thereby adjusting the tightness of the belt, thereby solving the problem of the tightness of the belt affected by the climate.

[0024] The rotating shaft 14 passes through the slider 15 on one side and rotates to connect to the signal board 12. The signal board 12 is long and has a proximity switch 11 on one side of the signal board 12. The proximity switch 11 is fixed on the outside of the slider 15. The signal board 12 rotates with the rotating shaft 14 to count with the proximity switch. If no pulse count is detected within the set time, an alarm will be issued to avoid the system from automatically shutting down during operation, which will cause the subsequent equipment to run in a chain.

[0025] A belt 3 is provided between the front driving roller 1 and the rear driven roller 7 for transmission connection. A number of V-shaped rollers 4 are evenly provided on the frame 9 between the front driving roller 1 and the rear driven roller 7 for supporting the upper belt. A number of hanging rollers 10 are evenly provided below the frame 9 between the front driving roller 1 and the rear driven roller 7 for supporting the lower belt. A front correcting wheel 2, a middle correcting wheel 5 and a rear correcting wheel 6 are provided in sequence on the frame 9 between the front driving roller 1 and the rear driven roller 7. The front correcting wheel 2, the middle correcting wheel 5 and the rear correcting wheel 6 have the same structure and are all self-adjusting correcting wheels, which effectively avoid the belt deviation phenomenon.

[0026] The frame 9 of the present invention adopts a simplified structure, which compresses the occupied space, and the front driving roller 1 is installed at the front end of the frame 9, which enhances the tensile strength and reduces the occupied space of conventional equipment placed above.

[0027] The front driving roller 1 adopts oil immersion cooling, which reduces the phenomenon of the driving system burning out the driving power due to overheating.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
