[0002] Coal mine belt conveyor is a commonly used transportation equipment, mainly refers to the belt conveyor used in the process of coal mining, production, transportation and processing. It has the characteristics of large transportation volume, complex working environment, strong carrying capacity and long transportation distance. When the belt conveyor works for a long time, the belt will often deviate. In order to prevent the belt deviation from affecting the normal operation of the equipment, a belt anti-deviation device is needed.

When in use, they can only limit the deviation of the belt and cannot correct the deviation of the belt or reset the belt. The belt may easily deviate for a long time and the fixed deviation roller may damage the belt edge. Therefore, a belt deviation correction and automatic resetting device is proposed.

The strong spring pulls the rotating block, causing the pressure roller to squeeze the belt of the belt conveyor. When the belt deviates, it squeezes the pressure roller, thereby driving the rotating block to pull the strong spring. The reset force generated by the strong spring can make the pressure roller generate a corrective force on the belt, thereby realizing the automatic correction and reset of the belt, thereby improving the correction and reset effect.

The wall of the stabilizing plate fits into the wall of the supporting plate. The rotating column is rotated to control the rotation of the threaded rod, which is convenient for adjustment and use. The stabilizing plate provides a limiting support to one end of the threaded rod to improve the rotation stability of the threaded rod.

[0009] Preferably, the support frame and the mounting ear plate are respectively arranged on both sides of one end of the support plate, and the cross-section of the pressure wheel is set to be "T"-shaped.

The rotating column 5 controls the threaded rod 6 to rotate, so as to adjust the distance between the two support plates 1, and limit one end of the threaded rod 6 by the stabilizing plate 7 to further improve the horizontal effect of the two support plates 1. One end of the support plate 1 is fixedly connected with a mounting ear plate 8, which facilitates the installation and fixation of the device by installing the ear plate 8;

The rotating block 10 is supported by the support frame 9, and the rotating block 10 is pulled by the strong spring 12, so that the pressure roller 11 has the effect of squeezing the belt of the belt conveyor. When the belt deviates, it will squeeze the pressure roller 11, thereby driving the rotating block 10 to pull the strong spring 12. The reset force generated by the strong spring 12 can make the pressure roller 11 generate a corrective force on the belt, thereby realizing the automatic correction and reset of the belt, and improving the correction and reset effect.
