Description

Technical Field

[0001] The invention relates to the technical field of mine blasting, and in particular to a mine blasting buffer device used in mine engineering. Background Art

[0002] Mine blasting is a key technology in the mining process. It uses the huge energy released by explosives in an instant to generate high-temperature, high-pressure and high-speed shock waves in the medium around the explosives, thereby destroying the structure of rocks or ore, breaking and loosening them to facilitate subsequent excavation, transportation and other operations. Mine blasting generally requires a buffer protection device to be set on the blasting surface.

[0003] Existing mine blasting buffer protection devices generally use protective plates, movable columns, springs and mounting plates to buffer and protect the gravel produced by the explosion. However, the gravel produced by the explosion will impact in different directions, causing the movable columns and the mounting plates to get stuck easily, making it difficult to achieve a certain buffer protection effect, thereby aggravating the deformation and damage of the protective plate.

[0004] To this end, we propose a mine blasting buffer device based on mining engineering. Summary of the invention

[0005] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a mine blasting buffer device for use in mining engineering.

[0011] Preferably, an externally threaded pipe is fixedly mounted on the inner wall of the flexible rubber connection liner.

The protective cover 25 drives the movable rod 16 to move rightward along the inner wall of the external threaded tube 22 on the flexible buffer connection seat assembly 18. The protective cover 25 compresses the first buffer compression spring 17 to generate deformation for buffering.
