Description

Technical Field

[0001] The utility model relates to the technical field of interval charging for blasting operations, in particular to an interval charging device for blasting operations. Background Art

[0002] In the field of blasting engineering, the effectiveness, safety, and cost control of blasting operations have always been key considerations. As a commonly used charging method, spaced charging plays an important role in improving blasting results, reducing the harm of blasting vibration, and saving explosives costs. Currently, in actual blasting operations, there is a need to continuously explore more efficient, accurate, and reliable spaced charging devices. Utility model patent publication number CN207300073U discloses a drilling and blasting charging rod. This device achieves the spacing of explosives by setting a baffle inside the charging rod, which to a certain extent provides a solution for spaced charging. However, due to the setting of the baffle, when the charging rod is withdrawn, it has certain requirements on the diameter of the blasthole. The baffle can easily move the explosives that have already been placed, which may lead to uneven distribution of explosives, affecting the blasting effect and even posing a safety hazard.

[0003] Furthermore, for higher blastholes, it is extremely difficult to manually extract the charging rod. As the height of the blasthole increases, not only does the operation become more difficult, but the safety risks for the operator also increase accordingly. At the same time, manual extraction cannot ensure the stability and consistency of the operation, and cannot meet the requirements of modern blasting engineering for automation and precision.

[0030] The medicine feeding rod 6 is provided with a plurality of adjustment slots 602 at intervals. A medicine clamping assembly 7 is installed at each adjustment slot 602 on the medicine feeding rod 6. The medicine clamping assembly 7 can slide in the adjustment slot 602 to adjust the spacing between adjacent explosive packs.
