Open-air deep hole blasting interval charging device

The utility model relates to the technical field of deep hole blasting, in particular to an open-air deep hole blasting interval charging device which comprises a deep hole, a right-angle abutting plate is installed in the deep hole in an inserted mode, a baffle ring is arranged at a port of the outer side of the deep hole, the right-angle abutting plate abuts against the inner wall of the end of the deep hole, and linearly-distributed extension plates are connected to the right-angle abutting plate in the direction of the port of the deep hole in an inserted mode. The explosive mounting device has the beneficial effects that the extension of the length of the mounting device is realized through the matching of the right-angle propping plate and the extension plate, so that the length of the mounting device is adaptive to deep holes with different depths, and meanwhile, the explosive is limited and clamped by using the mounting sliding blocks, so that the aim of interval distribution is fulfilled by limiting
