Blast hole plugging device for foundation pit blasting construction

The blast hole plugging device for foundation pit blasting construction comprises a moving platform, a positioning mechanism used for positioning the position of a blast hole and a mud pressing mechanism used for compacting plugging stemming in the blast hole are arranged on the moving platform, and a lifting hole is formed in the top of the moving platform; a linear module for driving the mud pressing mechanism to move up and down to enter and exit from the lifting hole and the blast hole is arranged at the top of the movable platform, and a clamping mechanism for fixing a detonator leg wire is arranged at the top of the movable platform. According to the device, through cooperation of the moving platform and the positioning mechanism, after the moving platform moves to a blast hole point position needing to be plugged, positioning alignment can be rapidly completed, and after a blast hole is filled with stemming and a detonator leg wire is clamped and fixed through the clamping mechanism, the mud pressing m
