Abstract
The invention relates to a tubular core-taking-out structure for a drilling tool. The tubular core-taking-out structure comprises a top-half tube and a bottom-half tube, wherein the top-half tube and the bottom-half tube are vertically connected in fastening mode. The two ends of the top-half tube and the two ends of the bottom-half tube are provided with external threads respectively, a plurality of protruding structures are arranged on the edges of the two sides of the bottom of the top-half tube respectively at intervals, inward bending structures are arranged on the edges of the two sides of the upper portion of the bottom-half tube respectively at intervals, and one side of each bending structure is provided with a groove structure matched with the corresponding protruding structure. The tubular core-taking-out structure is compact and reasonable in structure and convenient to operate. When a core needs to be taken out, separation of the top-half tube from the bottom-half tube is needed only, and the core can be taken out conveniently. When the tubular core-taking-out structure needs to be used again, the top-half tube and the bottom-half tube need to be fastened, and therefore the tubular core-taking-out structure is convenient and reliable to use and the working efficiency is improved.
Description
Technical field
The present invention relates to boring tool technical field, especially a kind of drilling tool corer structure.
Background technology
Probing is an important technical in geological prospecting work.Corer is the indispensable instrument of obtaining rock core in drilling process.During work, rock core need to be taken out.
Corer of the prior art, adopts common hollow cylinder body structure conventionally, and because the caliber of common corer is less, length is longer, during work, take out the rock core of tube interior compared with suffering, troublesome poeration, inefficiency.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of drilling tool rational in infrastructure corer structure, thereby can take out easily the rock core in corer, and easy and simple to handle, operating efficiency is high.
The technical solution adopted in the present invention is as follows:
A kind of drilling tool corer structure, comprise first pipe and second pipe of being fastened and connected up and down, the two ends of described first pipe and second pipe are respectively arranged with external screw thread, the two bottom sides edge of described first pipe is arranged at intervals with respectively a plurality of projective structures, the both sides of the edge, top of described second pipe are arranged at intervals with respectively inside bending structure, and a side of described bending structure has the groove structure matching with projective structure.
Further improvement as technique scheme:
Described projective structure is shape in echelon;
Described groove structure is shape in echelon.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, easy to operate, when needs removal of core, only need first pipe is separated with second pipe, can easily rock core be taken out, while reusing, only first pipe and lower tube half sub-buckle need be closed, easy to use and reliable, improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is explosive view of the present invention.
Wherein: 1, external screw thread; 2, first pipe; 3, second pipe; 4, projective structure; 5, bending structure; 6, groove structure.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the drilling tool of the present embodiment corer structure, comprise first pipe 2 and second pipe 3 of being fastened and connected up and down, the two ends of first pipe 2 and second pipe 3 are respectively arranged with external screw thread 1, the two bottom sides edge of first pipe 2 is arranged at intervals with respectively a plurality of projective structures 4, the both sides of the edge, top of second pipe 3 are arranged at intervals with respectively inside bending structure 5, and a side of bending structure 5 has the groove structure 6 matching with projective structure 4.
Projective structure 4 is shape in echelon.
Groove structure 6 is shape in echelon.
In actual use procedure, first pipe 2 is fastened and connected into hollow cylinder body structure with second pipe 3, the external screw thread 1 of corer upper end is connected ，Qi lower end external screw thread 1 with drilling tool is connected with drill bit.When driller completes, when corer has rock core, only need first pipe 2 is separated with second pipe 3, removal of core easily.It is easy to use and reliable, easy and simple to handle, and operating efficiency is high.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
Claims (3)
1. a drilling tool corer structure, it is characterized in that: comprise first pipe (2) and second pipe (3) that are fastened and connected up and down, the two ends of described first pipe (2) and second pipe (3) are respectively arranged with external screw thread (1), the two bottom sides edge of described first pipe (2) is arranged at intervals with respectively a plurality of projective structures (4), the both sides of the edge, top of described second pipe (3) are arranged at intervals with respectively inside bending structure (5), and a side of described bending structure (5) has the groove structure (6) matching with projective structure (4).
