Description

Technical Field

[0001] The present disclosure belongs to the technical field of drilling equipment, and particularly relates to a drill bit dust suction system with end dust suction holes. Background Art

[0002] When installing pipelines, dry drilling and hole opening are often required on the wall. During drilling, due to continuous friction between the drill bit and the wall surface, a large amount of dust is generated; these fine-particle dusts diffuse into the surrounding air, further disturbing the working area environment and at the same time affecting the line of sight of the staff, which is not conducive to the progress of the drilling work; in addition, due to the small volume of dust particles, they are extremely easy to be inhaled into the human body, posing a potential threat to the human body. Therefore, it is necessary to collect and process the dust generated during drilling to avoid a large amount of dust diffusing into the air during drilling; while most of the existing drilling equipment lacks the problem of timely exhausting and collecting the generated dust during operation.
