Description

Technical Field

[0001] The utility model belongs to the technical field of drilling equipment and relates to a drilling and dredging device. Background Art

[0002] In the past, during the process of drilling and reaming, it was necessary to lower a drill rod with a diameter similar to the hole and combine it with a corresponding drill bit to drill and dredge the hole until the drilling was completed. As the diameter of the borehole changed, it was necessary to lower drill bits of different degrees to match the borehole, which not only increased the cost but also increased the risk of drill dropping during the drilling and dredging process. Accidents such as drill sticking were always a possibility. In mining construction, filling boreholes, drainage boreholes, cable boreholes, etc. needed to be dredged every year. The common blockages in boreholes were mainly scale and the like. Using a drill bit of the corresponding diameter would increase additional costs and risks, and it would not be possible to clean out the scale and debris in the casing. Utility Model Content

[0006] Furthermore, the end of the casing away from the drill pipe forms a sawtooth end with a sawtooth structure.

[0007] Furthermore, the outer diameter of the casing is consistent with the diameter of the drill pipe.

[0008] Furthermore, the steel wire rope strand is composed of a plurality of steel wire ropes.

[0009] Furthermore, the diameter of the fixing plate is consistent with the inner diameter of the sleeve.
