Abstract
The utility model discloses a dust collection cover and a dust collection device using the same. An oppositely-buckled sealing face of the dust collection cover is located on an inclined plane which is inclined gradually downwards from the end where two dust collection cover half shells are detachably and fixedly connected to the end where the two dust collection cover half shells are hinged. The portion where the two dust collection cover half shells are hinged is located below the portion where the two dust collection cover half shells are detachably connected. When the dust collection cover is used, due to the fact that the portion where the two dust collection cover half shells are hinged is located below the portion where the two dust collection cover half shells are detachably connected, the torque required by the operation at the portion where the two dust collection cover half shells are detachably connected is reduced when the two dust collection cover half shells are opened or closed, more labor is saved during the assembling and disassembling operation of the dust collection cover, and the assembling difficulty is also correspondingly reduced.

The specific embodiment
The embodiment of dust trapping device in the utility model: as shown in Figures 1 to 9, this dust trapping device comprises the dust hood 1 of empty set in drilling rod periphery, by clip 2, be connected in and catch dirt sheath 3 in the outlet of drilling rod on dust hood 1, be fixed on the brush seal circle 4 in the drilling rod import of dust hood 1 and rotate on assembling dust hood in the depositing dust spray equipment 5 on brush seal circle 4 right sides, wherein dust hood 1 adopts oblique roller, it comprises dust hood half shell 11 and lower dust hood half shell 12, the upper surface of upper dust hood half shell 11 is for both relative make-up sealing surfaces that seal fastening with the lower surface of lower dust hood half shell 12, make-up sealing surface is in from right to left gradually on downward-sloping inclined-plane, the hinge 13 that upper dust hood half shell 11 and lower dust hood half shell 12 arrange by left side is hinged, and be provided with both removable fixed structures being connected in the right side correspondence of upper dust hood half shell 11 and lower dust hood half shell 12, this fixed structure comprise on the right side wall that is installed in dust hood half shell 11 on turn up lock seaming 14, be installed on lower dust hood 1 right side wall under turn up lock seaming 15 and screw be connected in turn up lock seaming 14 and under the trip bolt 16 of lock seaming on 15 that turn up, wherein trip bolt 16 is hexagon head unloosening screws, on the lock seaming of turning up offer the screw via hole 141 passing for trip bolt 16 on 14, this screw via hole 141 is the poroid slotted hole of twin-lock extending along left and right, on the right-hand member hole wall of screw via hole 141, be processed with the internal thread being threaded with trip bolt 16, the path of this internal thread is slightly larger than the width of screw thread via hole, under the lock seaming of turning up offer on 15 and the unthreaded hole section screwed hole 151 opposing upper and lower of screw via hole 141.
Between upper dust hood half shell 11 and lower dust hood half shell 12, be folded with the weather strip between make-up sealing surface, weather strip is the rubber strip being bonded on make-up sealing surface.On the front and back sidewall of upper dust hood half shell 11 and lower dust hood half shell 12, in position, the drilling rod import and export left and right sides, be welded with the stiffener 17 of strip, this stiffener 17 has formed the flange of inside turnover on the front and back sidewall of upper dust hood half shell 11 and lower dust hood half shell 12, and this flange is concordant with the lower surface of lower dust hood half shell 12 with the upper surface of upper dust hood half shell 11.
The front side of upper dust hood half shell 11 and lower dust hood half shell 12 is welded with half ring joint 18 in place, drilling rod exit position, two and half ring joints 18 relatively fasten and form circular jacket joint, and at the front end of half ring joint 18, convex with half ring flange 19 of half Flange-shaped Parts, before half ring flange 19 intervals are arranged in the leading flank of dust hood half shell 11 and lower dust hood half shell 12, the rear side ring end face of half ring flange 19 is half pre-large post-small annular conical surface.Corresponding, the rear end of catching dirt sheath 3 is provided with the dust hood joint corresponding with jacket joint, dust hood joint is provided with annular flange flange, annular flange flange on this dust hood joint and the annular flange flange on jacket joint are connected by clip 2 is removable, and the fit system between clip 2 and annular flange flange is cone match.Clip 2 comprise two mutual make-ups 21, two semi-ring collars 21 of semi-ring collar one end be hinged, the other end is bolted removable being connected, the nut 22 that wherein bolt coordinates in fastening bolt in connecting is wing nut.
In the present embodiment, the screw via hole 141 of the lock seaming 14 of above turning up is twin-lock hole, and in twin-lock hole, unthreaded hole diameter is less than screwed hole 151, and screwed hole 151 is consistent with the large end diameter of thread of trip bolt 16, and unthreaded hole is consistent with the polished rod diameter of trip bolt 16.During installation, trip bolt 16 is first twisted and is worn screwed hole 151, because polished rod diameter is less than the diameter of thread, so trip bolt 16 can move on to unthreaded hole position, the large end of trip bolt 16 and cap portion meeting block are on the two stomidiums edges up and down of screw via hole 141 simultaneously, so that the large end of trip bolt 16 is difficult for deviating from from screw via hole 141, like this after upper dust hood half shell 11 and lower dust hood half shell 12 make-up closures, the screwed hole 151 turning up in lock seaming 15 under only the large end of trip bolt 16 need being screwed in just can by upper dust hood half shell 11 and lower dust hood half, shell 12 be removable is fixed together.For folding does not affect sealing, the semi-ring collar 21 of clip 2 adopts semi-circular structure.
In the present embodiment, dust hood 1 obtains good hermetic seal effect by oblique roller, and makes dust hood half shell 11 and lower dust hood half shell 12 can better complete opening and closing movement.When dust hood 1 is closed, upper dust hood half shell 11 and lower dust hood half shell 12 by above turn up lock seaming 14 and under the turn up screw connection of lock seaming between 15 and the clip between jacket joint and dust hood joint 2 connect and realize relative fastening, so that upper dust hood half shell 11 and lower dust hood half shell 12 are realized conical surface seal by make-up sealing surface, coordinate, and the weather strip and the flange that by make-up sealing surface position, arrange carry out enhanced leaktightness effect.Like this, when drilling rod connecting portion enters dust hood 1 when interior, outward winding trip bolt 16 and clip 2, can open upper dust hood half shell 11 and lower dust hood half shell 12 of dust hood 1, realizes that drilling rod connects or de-; After upper dust hood half shell 11 and dust hood 1 half shell closures of dust hood 1, after tested, air leakage≤5% that it is total, tightness is good, avoids coal dust and methane gas to leak, so that the pump-line that methane gas can be communicated with by dust hood 1 right side is pumped.
In the above-described embodiments, dust hood by clip with catch that dirt sheath is removable to be connected, in other embodiments, the mode that is connected dust hood also can connect by flange, buckle connection etc. with catch that dirt sheath is removable to be connected.
In the above-described embodiments, upper dust hood half shell and lower dust hood half shell are connected by screw realizes removable being connected, and the fixed forms such as in other embodiments, upper dust hood half shell also can be connected by buckle with lower dust hood half shell, bolt connection realize removable being connected.
The embodiment of dust hood of the present utility model: in the present embodiment, the structure of dust hood is identical with the structure of dust hood in above-described embodiment, therefore repeats no more.
