Hydraulic belt deviation rectifying device

The utility model discloses a hydraulic belt deviation rectifying device which comprises an installation support, and the top of the installation support is rotationally connected with a deviation rectifying carrier roller assembly supported at the bottom of a conveying belt. After the deviation rectifying carrier roller assembly is driven by the deviation rectifying mechanism to rotate, the relative position between the conveying belt and the deviation rectifying carrier roller assembly is rectified; the deviation rectifying mechanism comprises hydraulic motors fixedly assembled on the two sides of the mounting support, detection driving wheels are arranged on the hydraulic motors, the conveying belt in the deviation state touches the detection driving wheels, the detection driving wheels rotate, and the hydraulic motors pump out high-pressure oil. The deviation correcting mechanism further comprises an oil cylinder pushing the deviation correcting carrier roller assembly to rotate, in the process of correct
