Three-wing drill bit for pipeline dredging

Abstract

The invention discloses a three-wing drill bit for pipeline dredging. The three-wing drill bit comprises a drill rod, tool clamping plates, water spraying holes and a supporting ring, wherein three wing plates are mounted on the outer side of the drill rod at equal intervals; brackets are mounted at the connecting parts of the wing plates and the drill rod; four mounting holes are uniformly formed in the tail end of each wing plate; the mounting holes penetrate through the inner and outer side surfaces of the wing plates; the tool clamping plates are mounted on the outer sides of the mounting holes; four groups of water spraying holes are symmetrically formed in the outer surface of the middle section position of the drill rod; the water spraying holes are communicated with the inner part of the drill rod; the supporting ring is mounted on the inner sides of the tail ends of the three wing plates; and three lifting rods are mounted between the supporting ring and the drill rod at equal intervals. According to the three-wing drill bit for pipeline dredging, the opening angles of the three wing plates can be adjusted, so that the size of a drill hole can be adjusted in a drilling process of the whole drill bit, and furthermore, sediment in a pipeline can be conveniently dredged through one-time drilling; the trouble of drilling for a plurality of times to dredge is avoided.

Description

technical field [0001] The invention relates to the technical field of drill tools, in particular to a three-wing drill bit for pipeline dredging. Background technique [0002] Pipeline dredging refers to dredging the pipeline, cleaning up the silt and other wastes in the pipeline, and keeping it unblocked for a long time to prevent urban waterlogging. If the pipeline is not regularly dredged, it will cause excessive sewage flow, pollute the environment, and bring troubles to people's lives. The pipe dredging bits currently used in the market are difficult to expand the drilling surface during use. When dredging thicker pipes, it is necessary to drill repeatedly. The whole operation is time-consuming and labor-intensive. Therefore, we propose a Three-wing drill bit is used for pipeline dredging. Contents of the invention [0003] The purpose of the present invention is to provide a kind of three-wing drill bit for pipeline dredging, to solve the problem that the pipeline...
