Mining double-liquid grouting equal-ratio mixing device

The utility model discloses a mining double-liquid grouting equal-ratio mixing device which comprises two slurry inlet pipelines, a three-way structure, a slurry outlet pipeline, an opening and closing mechanism, a sliding block and a spring. The opening and closing mechanism comprises an opening and closing baffle, a reset elastic piece and a semicircular gear, the center shaft rotates to drive the opening and closing baffle to rotate to open or close the slurry inlet pipeline, and the reset elastic piece enables the opening and closing baffle to be in a state of closing the slurry inlet pipeline initially; the sliding block can slide between the two slurry inlet pipelines; at the beginning of the spring, the other end of the sliding block extends into the three-way structure through the through hole, so that the first slurry inlet and the second slurry inlet are respectively closed with the slurry outlet; two gear discs are installed on the sliding block, gaps are reserved between the two semicircular gears
