Description
Technical field
The present invention relates to explosion rig field, relate in particular to a kind of dust diffusion that can prevent to produce in the rig operation process and the surface mine explosion rig of kicking up, and the dust guard that is used for this rig.
Background technology
Surface mine can produce a large amount of rock slags in using the rig process, the rock slag particle of discharging in boring footpath is not of uniform size, and particle diameter is more little, more difficult deposition, if do not control and handle, they will be dispersed in the production environment and go, the harm workers ' health.Trickle rock slag deposits can be quickened galling to machine movement part, influence the machine operate as normal, shortens rig application life.During punching, a large amount of dusts that drill bit produces to around spray, not only influence environment, and pass the sight line that dust that horizontal table upwards sprays influences the meeting operator.
Current, open-air mining-drilling machine dust pelletizing system is divided into two kinds of wet type and dry types by dedusting method.
Wet dedusting system mainly is made up of water supply installation, geomantic omen mixing arrangement, aperture slag-draining device etc.; During rig boring, the press water that water supply installation provides gets into the geomantic omen mixing arrangement, mixes with air pressure; The rock dust that feasible fragmentation is got off at the bottom of the hole and along in the hole wall uphill process by moistening; The rock dust pelletizing that congeals into moistening or semifluid magma drain into the aperture, blow to rig one side by the aperture slag-draining device.
The dry dust removal system directly separates the dirt gas mixture and captures, water not, better dust removal effect.The dry dust removal system mainly is made up of dust hood, flow tank, other chamber cyclone dust collectors, mechanical pulsing sack cleaner and ventilating fan.During rig boring, the pull-out type ventilating fan starts, and forms negative pressure in the dust pelletizing system dust hood, and dust gets into dust hood under the drive of rig return air.Particle diameter is in the dust major part sedimentation in dust hood more than 100 microns; The granule dust is sucked gravity settling chamber by ventilating fan, and when the dirt gas of extraction got into than the expansion chamber of large space suddenly, flow velocity reduced; The particle that settling rate is big becomes the rock slag at the bottom of falling into the chamber, is emitted by automatic slagging mechanism.Thinner little dust gets into other chamber cyclone dust collectors with air-flow from outlet, and in cyclone dust collectors, air-flow is rotated down under the guiding of spirality top board; Thick dust gets rid of to outer wall under action of centrifugal force, and descends along hand of helix, falls into and unloads the dirt device; Fine solid particle rises from stack with air-flow; Get into the mechanical pulsing sack cleaner, under the effect of ventilating fan, the dust that gets into deduster is delayed at the cloth bag periphery; Purge gas through the cloth bag filtration gets into upper box body, at last through going out to pile up.
The most basic requirement of dry dust removal system is can be earlier being surrounded to all dusts that spray all around before dust-filtering.This requirement is easy to realize in single angle boring fashion, yet when holing with multiple angles, just is surrounded very difficulty to dust fully.
Therefore, be necessary to improve dust pelletizing system, improve efficiency of dust collection, with the operating environment that guarantees cleaning and equipment application life of length.
Summary of the invention
In order to solve the aforementioned problems in the prior; The invention provides a kind of dust guard, it can be in the operation process of boring, prevents dust diffusion effectively and kicks up; And can move up and down and drilling rod multi-angle when creeping at drilling rod; At any time keep sealing, and a kind of rig with above-mentioned dust guard is provided, it does not need to establish in addition drive unit just can realize the dustproof function.
In order to achieve the above object; The invention provides a kind of dust guard that is used for surface mine explosion rig, the epimere of drilling rod partly is placed in the drilling cramp, and the hypomere of drilling rod partly passes horizontal table to extending below; Drilling rod creeps into downwards through the driving of unit head during boring; It is characterized in that said dust guard comprises a slidably horizontal table and contact and surround the drilling rod seal closure around the said drilling rod with said horizontal table, the dust of generation was enclosed in below the said horizontal table when said horizontal table and said drilling rod seal closure will holes effectively; Said horizontal table comprises sliding panel and fixed head; One rectangular aperture is arranged on the said fixed head, and the both sides of said rectangular aperture are provided with guide rail, and said sliding panel slides in said guide rail; One drilling rod seal closure opening is arranged on the said sliding panel, be used for placing said seal closure.
The dust that the slip of this dust guard through horizontal table produces in the time of can be effectively with boring is enclosed in below the horizontal table, thereby collects through other devices.
Preferably; Said sliding panel comprises: upper sliding plate: said drilling rod seal closure is positioned on the said upper sliding plate; Said drilling rod seal closure is fixed on said drilling cramp bottom, and said drilling rod seal closure can be swung thereupon when said drilling cramp was adjusted angle, moved horizontally thereby drive said upper sliding plate; The bottom surface of said upper sliding plate has chute, is used for being slidingly connected with said lower slider plate; The lower slider plate: the quantity of said lower slider plate is two, lays respectively at said drilling rod seal closure both sides, and the block of a convexity is arranged at the edge of said lower slider plate, and said block can embed the chute of said upper sliding plate and move along said chute; Can slide relatively between said upper sliding plate and the said lower slider plate; During beginning; Said lower slider plate is motionless, and said upper sliding plate moves horizontally, when said upper sliding plate slides into said lower slider panel edges; The said chute of said upper sliding plate begins to contact with said block, and drives said lower slider plate slip.
Preferably, around said drilling rod seal closure, be provided with a sealing ring on the said upper sliding plate, said sealing ring is fixed on the said upper sliding plate.
The present invention also provides a kind of surface mine explosion rig, comprises that drilling cramp rotational fuel tank, drilling cramp, drilling rod and drilling cramp support, and said drilling cramp rotates around the drilling cramp axis of rotation under the driving of said drilling cramp rotational fuel tank; The epimere partial fixing of said drilling rod in said drilling cramp, the hypomere of said drilling rod partly passes horizontal table to extending below, said rig also comprises aforesaid dust guard.
According to surface mine explosion rig of the present invention, simple in structure, do not need additional power system to go to drive.It drives sliding panel through the swing of drilling cramp when angle is crept into.Sliding panel and fixed head have the overlay region.The horizontal table complete closed avoided dust to kick up above the horizontal table when this overlay region can guarantee that drilling rod is holed under certain angle.
Compared with prior art, the present invention has following beneficial effect:
1,, can prevent effectively that dust from passing upwards diffusion of horizontal table through the setting of drilling rod seal closure;
2, through the slidably setting of horizontal table, can prevent effectively that dust from upwards kicking up, avoid dust to block operating personnel's sight line;
3, through the combination of drilling rod seal closure and sliding table, can guarantee drilling cramp horizontal table complete closed when creeping at a certain angle, avoid dust to kick up above the horizontal table;
4, according to rig of the present invention, dust guard is driven under the swing of drilling cramp, need not set up extra actuating unit, and simple in structure, device fabrication is easy, small investment, and system works is reliable, and compliance is strong, and efficiency of dust collection is high, long service life.
