Description

Technical Field

[0001] The utility model relates to the technical field of dust removal during coal mine tunnel excavation, in particular to a dust removal system for an integrated excavator and anchor machine. Background Art

[0002] When using a mining and anchoring machine to excavate coal mine tunnels, most of the time, airborne dust removal fans are used for dust removal. Airborne dust removal fans are mostly wet dust removal fans with a small dust removal volume. Their dust removal efficiency is slightly insufficient during tunnel excavation. In some schemes, the dust removal fan is arranged in the middle of the mining and anchoring machine. Due to the limitation of the equipment's external dimensions, the dust removal fan is small in size and cannot achieve a large dust removal volume. In other schemes, the dust removal fan is placed at the rear, usually at the tail of the self-propelled machine. The dust removal fan has a larger installation space and can be installed with a larger dust removal fan. However, the dust removal air duct of this scheme is long, and the distance from the dust removal fan to the face is too long, resulting in excessive loss of suction volume, and the actual dust removal effect is not ideal.

[0003] In summary, there is an urgent need to provide a dust removal system for an integrated miner and anchor machine to solve the problems existing in the prior art. Utility Model Content
