Mining belt conveyor with belt deviation protection function

The utility model discloses a mining belt conveyor with a belt deviation protection function. The mining belt conveyor comprises a back plate, and the top of the back plate is installed on a longitudinal beam through two U-shaped screws. The U-shaped screw is used for adjusting the angle of the back plate relative to the longitudinal beam by changing the relative position of the U-shaped screw and the longitudinal beam; the back plate is detachably connected with a mining deviation sensor, two sides of a main body of the mining deviation sensor are respectively provided with a waist-shaped groove, and the back plate is also correspondingly provided with two first long grooves; the mining deviation sensor is used for detachably connecting the kidney-shaped groove and the first long groove on the same side through a fastener. And the fastener is used for installing the mining deviation sensor at different positions of the first long groove so as to realize the adjustment of the relative position of the mining d
