Description
Technical field
The utility model is related to a kind of mine drill stem, more particularly to a kind of scalable mine drill stem.
Background technology
Colliery in process of production, must just carry out supporting, China is typically using anchor pole or anchor cable to lane to underworkings
Road carries out its support reinforcement, and this is accomplished by carrying out punching drilling to roadway surrounding rock.Drilling rod one end is connected on drill bit, one end connection
On rig.In drilling process, it is sometimes desirable to beat deep hole, conventional drill rod length can not meet requirement, it is necessary to using scalable
Drilling rod increases drilling depth.
Scalable mine drill stem is simple in construction, easy to use, strong adaptability, is used in the drilling that can be different depth.
The content of the invention
The utility model purpose be exactly in order to solve drilling rod connection when waste time and energy there is provided a kind of scalable mine drill stem,
It is simple to operate, it is easy to use.
The utility model includes：Drill bit, drilling rod, steel ball, fixed plate, spring.
The utility model is so completed：A kind of scalable mine drill stem is designed, drill bit and drilling rod are all hollow structures
And the two is attached by screw thread, two drilling rods are attached by elastic device.Elastic device is by two steel balls and spring
Constitute.
The utility model cuts the symmetrical circular hole of two equal sizes at drilling rod termination position, and circular hole can be by elasticity even
Connection device is attached.
The utility model is simple in construction, and cost is low, and convenient disassembly is practical, can be used for the brill of different drilling depths
Enter operation.
Brief description of the drawings
Fig. 1 is the utility model structural perspective.
Fig. 2 is the utility model front view.
Fig. 3 is the utility model upward view.
Fig. 4 is the utility model junction profile.
Fig. 5 is drilling rod schematic diagram after processing.
Embodiment
Embodiment of the present utility model is described with reference to the drawings.
Drill bit 1 is connected through a screw thread with drilling rod 2, and drilling rod 2 is connected with drilling rod 3 by elastic device, drilling rod 2 and fixed plate 5
By being welded and fixed.Drill bit 1 is mining both wings formula drill bit, and drilling rod 2 and drilling rod 3 are mining six ribs drilling rod, the external diameter and brill of drilling rod 2
The internal diameter size of bar 3 is identical, and drilling rod 2 cuts the symmetrical circular hole of two equal sizes with the termination position of drilling rod 3, and fixed plate 5 is located at
Both sides above and below the inner circular aperture of drilling rod 2, steel ball 4 and the material of spring 6 are high-strength alloy, and steel ball 4 totally two is symmetrical, are led to
Cross spring 6 to connect, the overall composition elastic connecting device after connection.
When drilling shallower, directly use in normal state, when drilling deeper, outside drilling rod is extracted upwards, made
Steel ball card is used behind drill rod end circular hole position, extension run of steel.
The utility model is simple in construction, and convenient disassembly, cost is low, practical, the drilling operation available for different hole depths.
