Description

Technical Field

[0001] The utility model relates to the technical field of integrated digging and anchoring machines, in particular to a fast integrated digging and anchoring machine for coal mines. Background Art

[0002] Coal is one of the most widely distributed fossil energy sources in the world and occupies a vital position in China's energy structure. Coal mining methods are mainly divided into open-pit mining and underground mining. Open-pit mining involves stripping off the overlying rock layer to expose the coal seam before mining. Underground mining requires excavating a series of shafts and tunnels to enter the underground coal seam and then mine the coal. In the process of tunnel excavation, the integrated drilling and anchoring machine is an indispensable device.

[0003] The coal mine rapid excavation and anchoring machine is an advanced coal mining equipment. It combines the functions of a tunneling machine and an anchor bolter, and can perform support operations simultaneously during the excavation process, thereby greatly improving the excavation efficiency and quality of coal mine tunnels. In existing devices, during the excavation of the tunnel, the excavated stones or coal are often collected by a rotating disk and transported out through a conveying device. However, in the process of collecting the stones or coal, a large amount of dust is often raised, which not only causes great harm to the health of construction workers, but also increases the risk of fire and dust explosion. Based on this, the present utility model is proposed. Utility Model Content
