Description
Technical field
The utility model belongs to Geological Engineering exploratory techniques field, particularly a kind of ground corer.
Background technology
Bolt, when getting ground, is directly put on the hole of slim hole joint by screw thread by traditional ground corer, and the ground soil structures disturbance of taking out like this is severe, uses inconvenience.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 ground corer.
Technical solution of the present utility model: a kind of ground corer, is characterized in that: comprise drill bit, core barrel, core barrel head, slim hole joint, steel ball; Described core barrel is fixed on core barrel head by screw thread; Described core barrel head is fixed on slim hole joint by screw thread; Described drill bit is connected with core barrel by screw thread; Described core barrel is the threaded hollow cylinders in two ends; .
Further, described core barrel head is hollow stepped cylindrical body, and large step height 100mm external diameter is 50mm internal diameter is 44mm, and small stair height 35mm external diameter is 22mm internal diameter is 4mm, the periphery of small stair there is trapezoidal thread, there is triangle thread the periphery of large step.
Further, described slim hole 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 4mm, and there is chamfering in the hole of one end, and the other end has the internal thread coordinated with core barrel small stair.
Further, on described steel ball by being welded with steel wire.
Further, the material of described drill bit is alloy steel.
beneficial effect:
Compared with prior art, ground 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;
In figure, 1-drill bit, 2-core barrel, 3-core barrel head, 4-slim hole joint, 5-steel ball.
Detailed description of the invention
As shown in Figure 1, a kind of ground corer of the present utility model, is characterized in that: comprise drill bit 1, core barrel 2, core barrel head 3, slim hole joint 4, steel ball 5; Described core barrel 2 is fixed on core barrel head 3 by screw thread; Described core barrel head 3 is fixed on slim hole joint 4 by screw thread; Described drill bit 1 is connected with core barrel 2 by screw thread; Described core barrel 2 is the threaded hollow cylinders in two ends; .
Wherein, described core barrel head 3 is hollow stepped cylindrical bodies, and large step height 100mm external diameter is 50mm internal diameter is 44mm, and small stair height 35mm external diameter is 22mm internal diameter is 4mm, there is trapezoidal thread the periphery of small stair, there is triangle thread the periphery of large step.Described slim hole joint 4 is axles that there is through hole in the center of circle, and the diameter of axle is 30mm, and through-hole diameter is 4mm, and there is chamfering in the hole of one end, and the other end has the internal thread coordinated with core barrel 2 small stair.By being welded with steel wire on described steel ball 5.The material of described drill bit 1 is alloy steel.
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.
