Description

Technical Field

[0001] The utility model relates to the technical field of blasting engineering auxiliary devices, in particular to a bottom drainage device for deep hole blasting in mines. Background Art

[0002] In the daily mining process of mining resources, blasting is often used. Blasting has brought convenience to people's daily mining. However, after deep hole blasting in mines, water often accumulates at the bottom of the hole and cannot be discharged. Faced with this situation, people often use water pumps or submersible pumps to drain the bottom of the hole.

[0003] Since the blasting hole is deep and the edge of the blasting hole is sharp, the existing deep hole blasting hole bottom drainage device in the mine will cause the water pipe to be cut when using plastic water pipe for drainage. Some devices use hoses with metal protective layers for drainage. Although the metal hose can effectively avoid cuts, it will also cause wear near the edge of the blasting hole. Once worn, it will cause water pipe leakage, making it difficult to drain the blasting hole, which is inconvenient to use. Utility Model Content

Threads are provided on the outer side of the adjusting disk 9 and the inner side of the adjusting ring 14. The adjusting ring 14 is threadedly connected to the adjusting disk 9. The outer side of the adjusting ring 14 is designed with an anti-skid structure to facilitate the adjustment of the extrusion support plate 12.
