Abstract
The utility model discloses a kind of have drag for sand function the angle of depression boring drilling rod, it comprises the drilling rod of an end band silk head and multiple diameter steel drum more smaller than drill bit, Tong Di center is provided with boring, the drilling rod other end is connected together with bucket back welding through rear successively from each barrel of subdrilling hole, requires that adjacent steel drum interval is welded on drilling rod.When using this drilling rod to hole, can remove in time in drilling process and produce sandstone and metal fragment, reduce the problem that drilling tool is ground repeatedly, improve drilling efficiency, extend the application life of drilling tool.
Description
Technical field
The utility model relates to probing aid, especially the drilling rod of angle of depression drilling construction.
Background technology
At present, in geology and complicated hydrogeological conditions, colliery that gas bearing capacity is high, need construction geology, hydrogeology and firedamp taking-out discharging drilling every year, and boring amount is large.Due to underground coal mine narrow space, be difficult to meet chemical slurry and creep into required place, generally creep into clear water, in clear water drilling process, often gather a large amount of sandstones and metal fragment at the bottom of the hole of angle of depression boring, drilling tool is ground repeatedly, drill tool life is shortened, and drilling efficiency reduces.In addition in Geology Drilling, need underlying orifice tube, so that the water yield in control hole, but because hole prodelta clay gathers a large amount of sandstone and metal fragment, orifice tube is difficult at the bottom of hole, and a large amount of clasts has a strong impact on the strengthening quality of orifice tube, then should ring the safety that discharges water of boring.Therefore, a kind of special fishing tool is sought after.
Summary of the invention
Salvage problem for solving the sandstone that gathers of foot of hole, the utility model design is a kind of has for the angle of depression boring drilling rod dragging for sand function.
Technical scheme is, a kind of have the angle of depression boring drilling rod dragging for sand function, it is characterized in that, it comprises the drilling rod of an end band silk head and multiple diameter steel drum more smaller than drill bit, Tong Di center is provided with boring, the drilling rod other end is connected together with bucket back welding through rear successively from each barrel of subdrilling hole, requires that adjacent steel drum interval is welded on drilling rod.
When creeping into angle of depression boring, by the silk head of drilling rod being installed drill bit, resembling common boring and starting construction.Produce sandstone and metal fragment in drilling process, by the space between water-band to each " little steel drum ", and be automatically precipitated to " little steel drum " bottom, propose together with drilling tool when carrying brill.In addition, drilling rod also can be used alone, and when finding that foot of hole gathers a large amount of sandstones and metal fragment, by drilling rod of the present utility model separately at the bottom of hole, by the current in drilling rod by chip at the bottom of hole " punching extremely " little steel drum, then carrying brill and pouring out.
When using this drilling rod to hole, can remove in time in drilling process and produce sandstone and metal fragment, reduce the problem that drilling tool is ground repeatedly, improve drilling efficiency, extend the application life of drilling tool.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment.
In figure: 1-drilling rod, 2-drill bit, 3-steel drum, 4-silk head.
Detailed description of the invention
Embodiment as shown in Figure 1, it comprises the drilling rod 1 of an end band silk 4 and 3 diameters steel drum 3 less than drill bit, the Tong Di center of steel drum 3 is provided with boring, drilling rod 1 other end is connected together with bucket back welding through rear successively from each barrel of subdrilling hole, requires that adjacent steel drum 3 interval is welded on drilling rod.During use, drill bit is arranged on drilling rod silk head.
