Abstract
The utility model relates to a mechanical vibrating mechanism for a mining slewing drilling machine, which is applicable to various mining slewing drilling machines with different structure and different power source and is particularly applicable in various downhole drilling operations like gas drainage, blasting, water and gas exploration, roof coal blasting, anchoring and bolting, crossing fault and crest slab management. The mechanical vibrating mechanism is composed of a shock excitation subassembly, a sleeve-like spigot shaft and a shell.
