The utility model discloses an automatic measuring device for blast hole charging height, which belongs to the technical field of blast hole charging detection equipment and comprises a support and a motor arranged on the support, a wire wheel is mounted at the output end of the motor, a first fixing frame is arranged on one side of the wire wheel, and a rotating shaft is mounted on the first fixing frame. And a second fixing frame is arranged on the other side of the wire wheel. The connecting line is driven by the balancing weight to move downwards from the blast hole, after the balancing weight makes contact with explosive in the blast hole, the upper end of the connecting rod makes contact with the proximity switch, and the height of the explosive in the blast hole is accurately detected through the proximity switch in cooperation with the meter counter after the height is detected. Or a connecting line with the specified length can be put into the blast hole through the meter counter, so that the balanci
