Abstract
The invention discloses a dedusting device for a down-hole hammer drilling machine. The device comprises a top hood, a seal ring (3) fitted with a drill stem is arranged on the top hood (1), a winding engine (4) is installed on the top hood, the upper end of a piece of cord fabric which is capable of mantling a sheathed tube is installed on the top hood, multiple steel support rings (9) are arranged on the cord fabric at intervals in the axial direction, and the tail end of a steel wire rope (5) twined on the winding engine (4) is fixed to the steel support ring (9) which is located at the bottommost position. In the working process, air flow carrying dust and sludge moves upward in an annular gap between the drill stem and the sheathed tube. When reaching the top hood, the air flow is bounced downward and guides the dust and the sludge to the ground through an annular gap between the cord fabric and the sheathed tube (8).
Description
Technical field
The present invention relates to a kind of dust arrester, particularly relate to a kind of dust arrester for DTH Large Diameter DTH Hammer hammer.
Background technology
In the course of the work, because air compressor machine air quantity is large, blast is high, rock dust, the body refuse of discharge are many for current down-hole hammer rig.Rock dust, body refuse are from sleeve aperture directly discharged in the air, and contaminated environment, damages health of human body, and enter the air intake filter of internal combustion engine, reduce the life-span of strainer and affect power of IC engine performance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dust and body refuse can avoided and blows to aerial down-the-hole hammer drill dust removal device from sleeve opening.
For solving the problem, down-the-hole hammer drill dust removal device provided by the invention, comprise an overhead guard, described overhead guard is provided with the sealing ring assembled with drilling rod, described overhead guard is provided with hoist engine, a upper end that can cover the cord of sleeve pipe is arranged on described overhead guard, and on described cord, interval is furnished with multiple steel pushing out ring vertically, and the end being wrapped in the wire rope on described hoist engine is fixed on the described steel pushing out ring of bottommost.
The described steel pushing out ring of mid portion is provided with aperture, and described wire rope is connected with the described steel pushing out ring of bottommost through the described aperture on the steel pushing out ring described in each from top to bottom successively.
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.
The upper end of described cord is tied up and is arranged on described overhead guard.
Adopt the down-the-hole hammer drill dust removal device of technique scheme, the height apart from ground bottom cord can be adjusted by folding and unfolding hoist engine.The different specification of the sealing ring replacing that circular overhead guard is installed is to adapt to the drilling rod of different-diameter.
During work, the air-flow that carry dust and body refuse moves upward from the annular gap between drilling rod and sleeve pipe.Air-flow rebounds downwards when arriving circular overhead guard, by the annular gap between cord and sleeve pipe, dust and body refuse is caused ground.
This dust arrester avoids dust and body refuse and blows to the environment pollution that brings and the infringement to constructor's health in the air from sleeve opening.
In sum, the present invention is that a kind of dust and body refuse can avoided blows to aerial down-the-hole hammer drill dust removal device from sleeve opening.
Accompanying drawing explanation
Fig. 1 is existing down-hole hammer deslagging schematic diagram;
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
See Fig. 1, current down-hole hammer rig in the course of the work, carries rock dust, the air-flow of body refuse moves upward from the annular gap between drilling rod 2 and sleeve pipe 8, finally in sleeve pipe 8 aperture directly discharged in the air.
See Fig. 2, down-the-hole hammer drill dust removal device provided by the invention, comprise a circular overhead guard 1, circular overhead guard 1 is provided with 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 is provided with hoist engine 4, a upper end that can cover the cylindrical shape cord 7 of sleeve pipe 8 is tied up and is arranged on circular overhead guard 1, on cylindrical shape cord 7, interval is furnished with multiple steel pushing out ring 9 vertically, and the end being wrapped in the wire rope 5 on hoist engine 4 is fixed on the steel pushing out ring 9 of bottommost.
Further, the steel pushing out ring 9 of mid portion is provided with aperture, and wire rope 5 is from top to bottom successively through the aperture on each steel pushing out ring 9, and the end of wire rope 5 is connected with the steel pushing out ring 9 of bottommost.
See Fig. 2, the height apart from ground bottom cylindrical shape cord 7 can be adjusted by folding and unfolding hoist engine 4.During work, the air-flow that carry dust and body refuse moves upward from the annular gap between drilling rod 2 and sleeve pipe 8.Air-flow is discharged in sleeve pipe 8 aperture, rebounds downwards, by the annular gap between cylindrical shape cord 7 and sleeve pipe 8, dust and body refuse are caused ground when arriving circular overhead guard 1.
