Abstract
The invention discloses a kind of down-the-hole hammer drill dust removal device, including an overhead guard, described overhead guard (1) is provided with the sealing ring (3) with drilling rod assembling, hoist engine (4) is installed on described overhead guard, the upper end of one cord that can cover sleeve pipe is arranged on described overhead guard, axially spaced apart on described cord to have multiple steel pushing out rings (9), the end for the steel wire rope (5) being wrapped on described hoist engine (4) is fixed on the described steel pushing out ring (9) of bottommost.During work, carry and moved upwards in annular gap of the air-flow of dust and body refuse between drilling rod and sleeve pipe.Bounce-back is downward when air-flow reaches overhead guard, and by the annular gap between cord and sleeve pipe (8), dust and body refuse are led into ground.
Description
Technical field
The present invention relates to a kind of dust arrester, is filled more particularly to a kind of dedusting for DTH Large Diameter DTH Hammer hammers
Put.
Background technology
At present down-hole hammer rig in the course of the work, because pneumatics fan delivery is big, blast is high, rock dust, the body refuse ratio of discharge
It is more.Rock dust, body refuse are directly arranged from sleeve aperture to aerial, pollution environment, infringement health of human body, and enter the air inlet of internal combustion engine
Filter, reduce the life-span of filter and influence power of IC engine playing.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of to be avoided that dust and body refuse blow to from sleeve opening aerial
Down-the-hole hammer drill dust removal device.
To solve the above problems, down-the-hole hammer drill dust removal device provided by the invention, including an overhead guard, described overhead guard
Provided with the sealing ring assembled with drilling rod, hoist engine, the upper end peace of a cord that can cover sleeve pipe are installed on described overhead guard
It is axially spaced apart on described cord to have multiple steel pushing out rings on described overhead guard, it is wrapped on described hoist engine
The end of steel wire rope be fixed on the described steel pushing out ring of bottommost.
The described steel pushing out ring of center section is provided with aperture, and described steel wire rope sequentially passes through each described from top to bottom
Steel pushing out ring on described aperture and the described steel pushing out ring of bottommost connect.
Described sealing ring can change the outfit different specifications to adapt to the drilling rod of different-diameter.
Described overhead guard is circular overhead guard, and described cord is cylindrical shape cord.
Tie up on described overhead guard the upper end of described cord.
Using the down-the-hole hammer drill dust removal device of above-mentioned technical proposal, by folding and unfolding hoist engine can adjust cord bottom away from
The height on ground.The different specification of the sealing ring replacing installed on circular overhead guard is to adapt to the drilling rod of different-diameter.
During work, carry and moved upwards in annular gap of the air-flow of dust and body refuse between drilling rod and sleeve pipe.Gas
Bounce-back is downward when stream reaches circular overhead guard, and by the annular gap between cord and sleeve pipe, dust and body refuse are led into ground.
The dust arrester avoids dust and body refuse and the environmental pollution that brings in the air is blowed to from sleeve opening and to workmen
The infringement of health.
In summary, the present invention is a kind of to be avoided that dust and body refuse blow to aerial down-hole hammer rig dedusting from sleeve opening
Device.
Brief description of the drawings
Fig. 1 is existing down-hole hammer deslagging schematic diagram；
Fig. 2 is the structural representation of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
Referring to Fig. 1, down-hole hammer rig in the course of the work, carries the air-flow of rock dust, body refuse from drilling rod 2 and sleeve pipe 8 at present
Between annular gap in move upwards, finally directly arranged to aerial in the aperture of sleeve pipe 8.
Referring to Fig. 2, down-the-hole hammer drill dust removal device provided by the invention, including a circular overhead guard 1, circular overhead guard 1 are set
There is the sealing ring 3 assembled with drilling rod 2, sealing ring 3 can change the outfit different specifications to adapt to the drilling rod of different-diameter, circular overhead guard 1
On hoist engine 4 is installed, the upper end of a cylindrical shape cord 7 that can cover sleeve pipe 8 is tied up on circular overhead guard 1, cylinder
The end of the axially spaced apart steel wire rope 5 for having multiple steel pushing out rings 9, being wrapped on hoist engine 4 is fixed on most bottom on shape cord 7
On the steel pushing out ring 9 in portion.
Further, the steel pushing out ring 9 of center section is provided with aperture, and steel wire rope 5 sequentially passes through each steel support from top to bottom
Aperture on ring 9, the end of steel wire rope 5 and the steel pushing out ring 9 of bottommost connect.
Referring to Fig. 2, height of the bottom of cylindrical shape cord 7 far from ground can be adjusted by folding and unfolding hoist engine 4.During work, take
Moved upwards in the annular gap between drilling rod 2 and sleeve pipe 8 with the air-flow of dust and body refuse.Air-flow is in the lines of orifices of sleeve pipe 8
Go out, bounce-back is downward when reaching circular overhead guard 1, by the annular gap between cylindrical shape cord 7 and sleeve pipe 8, by dust and body refuse
Lead to ground.
