Furthermore, in the description of the present invention, "plurality" means two or more, unless otherwise expressly and specifically defined.

[0025] This utility model provides, for example Figure 1-4The fixed permanent magnet roller belt conveyor shown includes a fixed frame 1, a driven roller 2 at one end of the fixed frame 1, a permanent magnet direct drive electric roller 3 at the other end of the fixed frame 1, a trough-shaped idler roller group 4 installed on the fixed frame 1, the trough-shaped idler roller group 4 being located between the permanent magnet direct drive electric roller 3 and the driven roller 2, a conveyor belt 5 being located between the permanent magnet direct drive electric roller 3 and the driven roller 2, a movable base 6 being located below the fixed frame 1, a vertical support plate 7 being installed at one end of the surface of the movable base 6, an L-shaped fixed plate 8 being installed on the vertical support plate 7, the L-shaped fixed plate 8 being located above the conveyor belt 5, a refraction plate 9 being installed at the vertical arm end of the L-shaped fixed plate 8, an infrared ranging sensor 10 being installed on the vertical support plate 7, the infrared ranging sensor 10 and the refraction plate 9 being on the same horizontal plane, and a vision camera 11 being installed on the L-shaped fixed plate 8.

[0026] When conveying materials, the permanent magnet direct-drive electric roller 3 starts working. The outer cylinder of the permanent magnet direct-drive electric roller 3 rotates to drive the conveyor belt 5. The conveyor belt 5 conveys materials on the trough roller group 4. The infrared distance sensor 10 starts working and projects infrared light onto the refraction plate 9. The refraction plate 9 reflects the infrared light back to the infrared distance sensor 10. When the material is high, the material will block the infrared light and cannot reflect it back to the infrared distance sensor 10. At this time, the permanent magnet direct-drive electric roller 3 operates at high power. When the refraction plate 9 reflects the infrared light back to the infrared distance sensor 10, the material is low and there is less material. The permanent magnet direct-drive electric roller 3 operates at low power. At the same time, the vision camera 11 detects the amount of material and can adjust the belt speed in real time, which reduces the wear of the conveyor belt 5 and equipment loss, improves energy saving, reduces operating costs, and saves maintenance costs.
