Abstract
The utility model relates to an orifice deduster. A bearing is fixedly arranged on the rear side of a shell body of the orifice deduster. A bearing sleeve is arranged outside the bearing in an encircling mode. A sliding groove is formed in the lower end of the bearing sleeve. The sliding groove of the bearing sleeve is fixedly connected with a fixing frame through pins. Top threads are correspondingly arranged on the lower side of the bearing. One end of a spiral blade is fixedly connected with an inner ring of the bearing. The other end, around a drilling rod, of the spiral blade is suspended in air. A core barrel is connected with the front side of the shell body. A water pipe interface is arranged at the upper end of the shell body. The water pipe interface is connected with a spraying nozzle which is arranged on the upper portion in the shell body. A lookout mouth and a discharging mouth are formed in the lower end of the shell body. The orifice deduster has the advantages that the orifice deduster can not only drive the spiral blade to rotate through the friction between the drilling rod and the bearing, but also is small in size, convenient and rapid to use, environment-friendly and energy-saving. Wet dust is stirred and discharged out of an orifice, and the purposes of removing dust and improving working environment are achieved.
Description
Technical field
The utility model relates to a kind of deduster, especially can be used for the orifice dust catcher of drilling in the colliery.
Background technology
At present, when China's coal-mine was carried out seam mining, because the coal seam is very dry, dust from flying when causing drilling operation produced serious dust pollution, not only threatens to operating personnel are healthy, and has great potential safety hazard.Prior art adopts the measures such as aperture spraying, full section spraying, and not only dust removing effects is general, and under mine, the installation and maintenance of machinery is also cumbersome, has brought very large inconvenience for people's production operation.
The utility model content
In order to improve the efficiency of dust collection of mine drill orifice, the utility model provides a kind of orifice dust catcher, this orifice dust catcher not only can drive by the friction of drilling rod and bearing the helical blade rotation, moistening dust is stirred make its more abundant wetting rear delivery port, reach the purpose that dedusting improves working environment, and fill part without electrical equipment, dedusting structure is simple, volume is little, and is convenient to use, environmental protection and energy saving.
the technical scheme that its technical problem that solves the utility model adopts is: this orifice dust catcher comprises bearing, waterpipe jointing, spray nozzle, helical blade, housing, core barrel, the mouth of serveing as a lookout, discharging opening, jackscrew, fixed mount, sliding pin, bearing holder (housing, cover), this orifice dust catcher is provided with a housing cylindraceous, the rear side of housing is installed with bearing, the bearing outside is surrounded by the lower end with the bearing holder (housing, cover) of sliding tray, the sliding tray place of bearing holder (housing, cover) is fixedly connected with fixed mount by pin, bearing holder (housing, cover) downside correspondence is equipped with jackscrew, the interior ring of bearing is fixedly connected with an end of helical blade, helical blade surface is equipped with one deck fine hair, fine hair plays the effect of better coal dust being adsorbed and going out and remove, the other end of helical blade after around drilling rod is unsettled, the housing front side is connected with core barrel, the housing upper end is provided with waterpipe jointing, waterpipe jointing is connected with the interior top spray nozzle of housing, housing bottom is provided with serve as a lookout mouth and discharging opening.During use, bearing drives the helical blade rotation, the water-wet of spray nozzle ejection simultaneously coal dust, helical blade stirs discharges discharging opening with wetting dust slurry, when reverse boring, wetting dust slurry can be discharged to mouthful discharging of serveing as a lookout, thereby reaches the effect of safe and efficient dedusting.
The beneficial effects of the utility model are that this orifice dust catcher not only can drive by the friction of drilling rod and bearing the helical blade rotation, and the dust after moistening is stirred delivery port, reach the purpose that dedusting improves working environment, and volume is little, and is convenient to use, environmental protection and energy saving.
