Abstract
A kind of dustproof drill lever apparatus, it is characterized in that, the drilling rod comprising guard aperture pipe, collector and be located in guard aperture pipe and collector, described collector is connected to the tail end of guard aperture pipe, collector top is provided with gas exhaust mouth, atomizer from front to back successively, coal, gas delivery port is provided with bottom described collector, being positioned at bottom the collector below atomizer is an inclined-plane turned forward, described collector afterbody corresponds to guard aperture pipe and axially arranges the boring of passing for drilling rod, and described drill hole is provided with dust seal.The utility model increases drencher head at the afterbody of collector, effective dedusting can be carried out to dust in collector on the one hand, and drilling rod is effectively rinsed, avoid drilling rod to be involved in seal by ickings, on the other hand, the mist curtain that atomizer capitiform becomes also serves the water seal effect to methane gas.
Description
Technical field
The present invention relates to coal drilling device, especially a kind of dustproof drill lever apparatus.
Background technology
Hydraulic mining is adopted to be a kind of economical and practical and safe and reliable digging means for thin soft seam, but after hydraulic fracturing, a large amount of coal, water, gas will be concentrated by boring and pour in collector, owing to adopting seal to seal between collector afterbody and drilling rod, after coal, water, gas enter collector, ickings is easily involved in seal by drilling rod, causes seal impaired, not only increase maintenance cost, and have impact on efficiency of construction.
Utility model content
The weak point that the utility model exists in order to avoid prior art, provides a kind of dustproof drill lever apparatus, and this device can provide stronger safeguard protection for seal, guarantees that the safety of coal seam drilling is carried out.
The technical scheme that the utility model technical solution problem adopts is:
A kind of dustproof drill lever apparatus, its design feature is, the drilling rod comprising guard aperture pipe, collector and be located in guard aperture pipe and collector, described collector is connected to the tail end of guard aperture pipe, collector top is provided with gas exhaust mouth, atomizer from front to back successively, coal, water delivery port is provided with bottom described collector, being positioned at bottom the collector below atomizer is an inclined-plane turned forward, described collector afterbody corresponds to guard aperture pipe and axially arranges the boring of passing for drilling rod, and described drill hole is provided with dust seal.
The utility model design feature is also:
Described atomizer is multiple atomizer, and shower nozzle spray direction is in turning forward.
Laterally be provided with high rear low tilt clapboard before in described storage, the rear end of described dividing plate and collector have gas passage gaps.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model increases drencher head at the afterbody of collector, effective dedusting can be carried out to dust in collector on the one hand, and drilling rod is effectively rinsed, avoid drilling rod to be involved in seal by ickings, on the other hand, the mist curtain that drencher head is formed also serves the sealing effectiveness to methane gas.
Accompanying drawing explanation
Fig. 1 is the utility model dustproof drill lever apparatus structural representation.
Number in the figure: 1 guard aperture pipe; 2 collectors, 21 gas exhaust mouths; 22 coals, water delivery port, 3 atomizers, 4 seals; 5 drilling rods, 6 dividing plates.
Below by way of detailed description of the invention, by reference to the accompanying drawings, detailed description of the invention that the utility model is described in further detail.
Detailed description of the invention
As shown in Figure 1, dustproof drill lever apparatus, the drilling rod 5 comprising guard aperture pipe 1, collector 2 and be located in guard aperture pipe and collector, collector 2 is connected to the tail end of guard aperture pipe 1, collector top is provided with gas exhaust mouth 21, atomizer 3 from front to back successively, coal, water delivery port 22 is provided with bottom collector, being positioned at bottom the collector below atomizer is an inclined-plane turned forward, collector afterbody corresponds to guard aperture pipe and axially arranges the boring of passing for drilling rod, and drill hole is provided with dust seal 4.
As shown in Figure 1, atomizer 3 is multiple atomizers 3 (more than 2), and shower nozzle spray direction is in turning forward.
Laterally be provided with high rear low tilt clapboard 6 before in collector, the rear end of described dividing plate and collector have gas passage gaps.
