Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal devices, and more specifically, it relates to a dust removal machine device for tunneling. Background Technology

[0002] In fully mechanized tunneling operations, the use of high-efficiency, high-power tunneling machines and transport machines improves tunneling efficiency and material handling capacity. However, the amount of mine dust in the tunnel increases dramatically, directly causing the dust concentration in the construction area to rise to a high level. This not only worsens the working environment and affects the health and safety of workers, but may also lead to equipment failure and safety hazards. In order to ensure both high efficiency and safety in construction, we must scientifically equip the fully mechanized tunneling machine with dust removal equipment specifically designed for fully mechanized tunneling operations.

[0003] Existing dust removal equipment for tunneling often requires adjustments to the ventilation duct based on various factors such as limited roadway space and changes in tunneling progress. The equipment cannot easily adjust the ventilation duct of the exhaust negative pressure type as needed, which can limit dust removal efficiency, increase the burden on operators and working time, and make it difficult to divert airflow to adjust the air volume as needed. It also makes it inconvenient to quickly disassemble and maintain the monitoring and identification device. Utility Model Content
