Description
Technical field
The utility model belongs to drilling rig technique field, specifically, relates to a kind of borer drill rod helical slag removing machine structure.
Background technology
When rig is digged pit operation, drill bit, around vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion of drill bit and responsive to axial force, destroyed and smash and ravel under the extruding of drill tip and centrifugal action, forms native stream and presses to hole wall, simultaneously along page elevator to earth's surface.Stop and when place because centrifugal action hack is thrown hole around, complete the whole process of digging pit when native stream moves to without hole wall.
And in boring procedure, holed when dark, in boring, the hack of accumulation is too much, can increase the rotational resistance of drill bit, and native stream is while moving to outside hole, and hack is thrown outside hole, and the airborne dust of formation can pollute the environment.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide one fast airborne dust and native slag in boring to be discharged, and airborne dust and hack slag are collected to the borer drill rod helical slag removing machine structure of getting rid of.
The utility model object is achieved in that a kind of borer drill rod helical slag removing machine structure, comprise drilling rod, drill bit, lower support and drill boom, described lower support is set in described drilling rod bottom, and be fixedly connected with described drill boom, its key is: the sidewall of described lower support is provided with tracheae, and the lower end of described lower support is fixed with leather cup; Between described drilling rod and drill bit, be provided with helical axis, described drilling rod lower end is fixedly connected with described helical axis upper end, the lower end of this helical axis is fixedly connected with described drill bit, in described helical axis, be provided with through hole, described through hole is along the axial setting of described helical axis, and this through hole communicates with the high pressure gas passage in described drilling rod and drill bit.
Adopt said structure, when drill hole of drilling machine, tracheae communicates with boring, and tracheae is communicated with deduster, and leather cup has covered boring, under the drive of helical axis and the promotion of high pressure gas, the native slag that bit cutting forms moves upward, in the time that native slag is pushed to outside hole, the airborne dust that leather cup is taken native slag out of blocks, and under the effect of deduster, airborne dust and native slag are sucked in deduster, native slag and airborne dust are collected and stacked, free from environmental pollution, the native slag producing can also be recycled.
The root diameter of above-mentioned helical axis equals the external diameter of described drilling rod, and the thread external diameter of described helical axis equals the external diameter of described drill bit.
Adopt said structure, the native slag that bit cutting produces can be taken away by helical axis smoothly, and the external diameter of drilling rod equals helical axis root diameter, is convenient to native slag and from thread, takes Shi Buhui out of and produce extra resistance, is convenient to native slag and discharges.
Above-mentioned helical axis is all fixedly connected with by screw thread with drill bit with drilling rod, and upper end, lower end screw thread and the direction of circling of thread of described helical axis are identical with the direction of rotation of drilling rod.
Adopt said structure, in rig operation, direction of circling is identical, makes the tight direction of direction of rotation and threaded bolt identical, thereby in running, is threaded and can not becomes flexible, to guarantee the normal operation of work.
Above-mentioned lower support comprises inner core and urceolus, described urceolus is set on described inner core, between described urceolus and described inner core, be provided with sealing ring and fixed support, sealing circle is positioned at the upper end of urceolus, described fixed support is positioned at the bottom of described urceolus, and the sidewall of described urceolus is provided with holder and described tracheae, and this tracheae communicates with the gap between described urceolus and inner core, the lower end of described urceolus is fixed with leather cup, and described inner core is set in the bottom of described drilling rod.
Adopt said structure, the inner core of lower support and the gap of urceolus form certain cavity structure, and this cavity upwards communicates with tracheae, communicate downwards with boring, guarantee passing through of airborne dust and hack slag.
Beneficial effect: a kind of borer drill rod helical slag removing machine of the utility model structure, when rig work, effectively the airborne dust to the interior generation of holing and hack slag are got rid of, collect and stack, and airborne dust is free from environmental pollution, and hack slag can reuse, and economizes on resources.
