[0002] In the field of engineering blasting, such as mining, infrastructure construction, etc., blast hole backfilling is an important link of blasting operation. The traditional backfilling method has problems such as low efficiency, unstable quality, and high safety risk. For example, manual filling of blast holes not only has high labor intensity and low efficiency, but also cannot guarantee the backfilling quality, affecting the blasting effect, and also exposing the operating personnel to dust and blasting hazards. In addition, some simple backfilling devices also have many deficiencies when facing complex geological conditions and large-scale operations. Therefore, a blast hole backfilling device is needed to solve these problems.

The blast hole plugging backfilling device can screen out blocky materials in the plugging materials such as rock powder, drill cuttings and loess through the sieve plate, avoiding blockage of the blast hole by blocky materials and the danger of being hit and flying during blasting. While pouring the plugging materials, the tamping rod can be used to operate the vibration simultaneously, the plugging materials in the blast hole are compacted layer by layer through the tamping rod, and the compaction effect is improved.
