Description

A kind of rubble corer
Technical field
The utility model belongs to Geological Engineering exploratory techniques field, particularly a kind of rubble corer.
Background technology
Traditional rubble corer, when getting rubble, adds water in corer, and rubble is removed under the effect of mud, or inserts a steel wire in corer, is taken out by rubble.Such method, inefficiency, cost of labor is large.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of rubble corer.
Technical solution of the present utility model: a kind of rubble corer, comprises drill bit, core barrel, core barrel joint, tool joint; One end of described drill bit has the screw thread other end to have blade; Described core barrel is connected with drill bit, core barrel joint by screw thread.
Further, described core barrel is hollow cylinder; Described core barrel joint and tool joint are fixed by screw thread, core barrel joint is hollow stepped cylindrical body, large step height 120mm external diameter is 45mm internal diameter is 35mm, small stair height 30mm external diameter is 22mm internal diameter is 10mm, the periphery of small stair there is trapezoidal thread, there is triangle thread the periphery of large step.
Further, described tool joint is the axle that there is through hole in the center of circle, and the diameter of axle is 30mm, and through-hole diameter is 10mm, and there is the internal thread coordinated with core barrel small stair one end.
Further, the inside of described drill bit is fixed with steel wire, and one end of steel wire is welded on the same plane of drill bit internal surrounding, and the other end of steel wire and other steel wires intersect.
Further, the material of described drill bit is diamond.
beneficial effect:
Compared with prior art, rubble corer of the present utility model, easy to use, get core better quality, improve operating efficiency, reduce costs.
accompanying drawing illustrates:
Fig. 1 is structure chart of the present utility model;
Fig. 2 is upward view of the present utility model;
In figure, 1-steel wire, 2-drill bit, 3-core barrel, 4-core barrel joint, 5-tool joint.
Detailed description of the invention
As shown in Figure 1, a kind of rubble corer of the present utility model, comprises drill bit 2, core barrel 3, core barrel joint 4, tool joint 5; One end of described drill bit 2 has the screw thread other end to have blade; Described core barrel 3 is connected with drill bit, core barrel joint 4 by screw thread.
Wherein, described core barrel 3 is hollow cylinders; Described core barrel joint 4 and tool joint 5 are fixed by screw thread, core barrel joint 4 is hollow stepped cylindrical bodies, large step height 120mm external diameter is 45mm internal diameter is 35mm, small stair height 30mm external diameter is 22mm internal diameter is 10mm, the periphery of small stair there is trapezoidal thread, there is triangle thread the periphery of large step.Described tool joint 5 is axles that there is through hole in the center of circle, and the diameter of axle is 30mm, and through-hole diameter is 10mm, and there is the internal thread coordinated with core barrel 3 small stair one end.The inside of described drill bit 2 is fixed with steel wire 1, and one end of steel wire 1 is welded on the same plane of drill bit 2 inside circumference, and the other end and other steel wires 1 of steel wire 1 intersect.The material of described drill bit 2 is diamonds.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
