The upper end closed of guide cylinder is simultaneously provided with rubber seal realization dynamic sealing on drilling rod via, and the drilling rod is horizontal by folder
Angle α, and 0 ° of 90 ° of ＜ α ＜, deduster are vertically installed at the underface of guide cylinder and are communicated with the inner cavity of guide cylinder, and deduster is
Double-layer coaxial circular short tube, the cyclic annular interlayer that inner and outer pipes are formed is closed at both ends, is distributed with a large amount of hole for water spraying in inner tube, on outer tube
It is provided with high pressure water access tube, when the air stream for carrying dust in drilling passes through deduster, is sent into high pressure water access tube
The high pressure water and water mist inwardly sprayed through deduster inner tube hole for water spraying comes into full contact with, becomes wet bulb or mud, under the effect of gravity,
It is discharged through deduster bottom.
The osculum end of the tubaeform dust gathering arrester is perpendicular to drilling rod as a preferred embodiment of the above solution, tubaeform dust gathering arrester
Big opening end is obliquely installed with respect to drilling rod, the inclined hole drilling well for different angle, it is only necessary to replace tubaeform dust gathering arrester, it is ensured that loudspeaker
The big opening end diameter of shape dust gathering arrester is consistent, you can realizes the general of pressure bladder.
Further, the tubaeform dust gathering arrester is welded and fixed with guide cylinder, and deduster is welded and fixed with guide cylinder, welding peace
The sealing effect of dress is more preferable.
The utility model has the beneficial effects that：It is simple in structure, manufacturing cost is low, it is light-weight, occupy little space, can flexibly use
It drills in the anchor shaft anchor cable of the scaffolds operation such as high slope, deep basal pit and Unstable Rock Treatment；Made using totally enclosed type high pressure water veil
Dust becomes wet bulb or mud, and is automatically drained out using gravity, to realize green probing, effectively solves environmental pollution and guarantor
Nurse's human body health, the well head dedusting being adapted under all devices and execution conditions have been filled up in addition to large scale equipment operation
Air drilling dedusting blank.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the deduster perspective view with high pressure water access tube.
Specific implementation mode
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：
As shown in Figure 1, a kind of drilling equipment well head dust-extraction unit, mainly by tubaeform dust gathering arrester 1, guide cylinder 2, dedusting
Device 3, pressure bladder 4, high pressure water access tube 5 form.
Tubaeform dust gathering arrester 1 is co-axially mounted rear enclosure on the drilling rod 6 of drilling equipment with guide cylinder 2, it is preferable that tubaeform collection
Dust hood 1 is welded and fixed with guide cylinder 2.
Tubaeform dust gathering arrester 1 divides big opening end and osculum end, the big opening end of tubaeform dust gathering arrester 1 to cover in well head, and by tight
The pressure bladder 4 of patch well head prevents dust from leaking, and the osculum end of tubaeform dust gathering arrester 1 is welded with the lower end of guide cylinder 2.
The upper end closed of guide cylinder 2 is simultaneously provided with rubber seal realization dynamic sealing on drilling rod via, and drilling rod 6 was crept into
Cheng Zhong, tubaeform dust gathering arrester 1, guide cylinder 2, deduster 3, pressure bladder 4, high pressure water access tube 5 are fixed not as a whole
It is dynamic.
Drilling rod 6 is horizontal by angle α, and 0 ° of 90 ° of ＜ α ＜, deduster 3 are vertically installed at the underface of guide cylinder 2, and
It is communicated with the inner cavity of guide cylinder 2, deduster 3 is welded and fixed with guide cylinder 2.
As shown in Figure 1, Figure 2, deduster 3 is double-layer coaxial circular short tube, two end seal of cyclic annular interlayer that inner and outer pipes are formed
It closes, a large amount of hole for water spraying 3a is distributed in inner tube, high pressure water access tube 5 is provided on outer tube.
When carrying the air stream of dust by deduster 3 in drilling, the high pressure water and warp be sent into high pressure water access tube 5
The water mist that 3 inner tube hole for water spraying 3a of deduster inwardly sprays comes into full contact with, and becomes wet bulb or mud, under the effect of gravity, through dedusting
3 bottom of device is discharged.
The osculum end of tubaeform dust gathering arrester 1 is set perpendicular to drilling rod 6, the big opening end of tubaeform dust gathering arrester 1 with respect to the inclination of drilling rod 6
It sets, the inclined hole drilling well for different angle, it is only necessary to replace tubaeform dust gathering arrester 1, it is ensured that the big opening end of tubaeform dust gathering arrester 1 is straight
Diameter is consistent, you can realizes the general of pressure bladder 4.
Gap of the dust generated in drilling process between drilling and hole wall is blown out using high pressure gas in drilling rod, is led to
The big opening end for crossing tubaeform dust gathering arrester 1 covers in well head, can preferably collect dust, and dust is finally blown to guide cylinder 2, deduster
3 connect pressure water by high pressure water access tube 5 forms interior spray high pressure water veil, contacts to form wet bulb or mud with dust, through dedusting
3 bottom of device is discharged.Since deduster 3 is arranged in the underface of guide cylinder 2, dust, which is once contacted with high-pressure water mist, just becomes wet bulb
Or mud, dust removing effects are very good.
