Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to earth and rock blasting, and specifically relates to a landfill device used for earth and rock blasting. Background Art
[0002] Earthwork blasting refers to a widely used construction method in which explosive materials such as explosives and detonators are used to blast earthwork in the construction of roads, bridges, mines, tunnels, water conservancy and hydropower, site leveling, foundation pits, pile holes, pipeline trenches, etc., in order to achieve the purpose of excavation. In earthwork blasting projects, after the charge in the blasthole is completed, the remaining blasthole section needs to be filled to fully utilize the energy of the explosives and reduce the purpose of flying rocks. At present, the more common method is to use a funnel to introduce the filling material into the blasthole to achieve the purpose of backfilling. However, the traditional backfilling funnel structure is relatively simple. In the process of backfilling the blasthole, the backfill material in the backfilling funnel is easy to cause blockage to the discharge port of the backfilling funnel, thereby affecting the normal backfilling operation of the backfilling funnel, resulting in the blasthole being not fully filled, reducing the utilization rate of the explosive energy, and the landfill equipment needs to be moved to the position directly above the blasthole for landfilling, which is inconvenient to operate during the actual construction process.
[0003] In view of this, the present utility model is proposed. Utility Model Content
