Abstract
The utility model relates to a lengthened non-coring drainage bit, in particular to a lengthened non-core drainage bit for downhole water detection in coal mines, which consists of three bit vanes, a lengthened centering pipe and an adapter connector, wherein, hard alloy layers are provided on the upper ends of the three bit vanes and a plurality of drainage circular apertures are arranged around the bit and the lengthened centering pipe; for the bit, the front end is connected with three bit vanes, on the middle part, the lengthened centering pipe is arranged, and on the rear end, the adapter connector and a drainage conduct are arranged; on the adapter connecter, screw threads and the drainage conduct which is connected with a drainpipe are arranged. The utility model has the advantages that the structure is simple, the operation is convenient and mud and sand are separated from water, so that the downhole water detection operation can be conducted safely; the drainpipe and laneway is unobstructed, and the work efficiency is enhanced. Thereby, the utility model can be broadly applied in downhole water detection operations.
Description
Technical field:
The utility model relates to a kind of lengthening and leaks borehole bit, especially coal mine test water with the lengthening borehole bit that leaks.
Background technology:
Coal mine test water construction in the prior art, often run into drift sand formation, after adopting common borehole bit to creep into to carry brill, drift sand easily with water from the interior outflow of holing, be unfavorable for that effectively mediation discharges water, the silt of outflow causes the drainage pipe alluvial to stop up, and is unfavorable for phreatic discharging, a large amount of silts flow out underground work are counteracted, and whole tunnel is stopped up in the silt alluvial.
Summary of the invention:
The purpose of this utility model provides a kind of lengthening borehole bit that leaks, it is to take to be provided with on the borehole bit body many circular holes that leak, solve the problem that silt goes out from the interior mixed flow of holing with water, silt and moisture from, reach coal mine test water construction safety, drainage pipe and tunnel are unobstructed, increase work efficiency.
The utility model lengthening borehole bit that leaks takes following technical scheme to realize, it is to be made of drill bit fin and lengthening guiding pipe and connector, three drill bit fin upper ends are provided with hard alloy layer, drill bit and lengthening guiding pipe periphery are provided with many circular holes that leak, chisel edge connects three drill bit fins, in the middle of the drill bit lengthening guiding pipe is set, and the drill bit rear end is provided with connector and draining sleeve pipe, screw thread and draining sleeve pipe are set on the connector, and the draining sleeve pipe is connected with gutter.
Effect of the present utility model is simple in structure, and is easy to operate, silt and moisture from, reach coal mine test water construction safety, drainage pipe and tunnel are unobstructed, increase work efficiency, and are widely used in coal mine test water construction works.
Description of drawings:
The utility model lengthening borehole bit that leaks will describe in further detail in conjunction with the accompanying drawings.
Fig. 1 is the leak structural representation of borehole bit of the utility model lengthening.
Fig. 2 is the leak head construction schematic diagram of borehole bit of the utility model lengthening.
