This scheme is bloied through the circulation, greatly reduced dust pollution, realized dustless turn into the industry.
Description
Technical field
This utility model relates to engineering spouting plant, particularly to a kind of pulp shooting machine.
Background technology
Pulp shooting machine, is that one is efficiently whitewashed machinery, is mainly used in mine/tunnel/culvert/subway and the construction of shotcrete operation of coal mine tunnel.But there is the problem that dust is big during existing pulp shooting machine operation, staff's health is impacted, it is easy to cause the various disease such as pulmonary infection, pneumoconiosis.
Utility model content
The purpose of this utility model is in that to provide a kind of pulp shooting machine, by circulating blowing, greatly reduces dust pollution, it is achieved dustless equalization.
Above-mentioned purpose of the present utility model has the technical scheme that a kind of pulp shooting machine, including frame, screw feed mechanism it is provided with in frame, screw feed mechanism includes charging aperture, discharging opening and the screw rod for conveying that falls between, the hopper of inverted cone it is connected with above charging aperture, screw rod is hollow structure and is internally formed vent line, vent line afterbody connects source of the gas, vent line head stretches to discharging opening, discharging opening outlet is arranged over dust shield, and dust shield connects with the inlet scoop of source of the gas.
By adopting technique scheme, the wind that source of the gas is discharged from vent line is absorbed to return to re-use by dust shield；Meanwhile, dust shield can absorb airborne dust major part come in, and has stopped spreading of dust from discharging opening so that the airborne dust of working environment is substantially reduced,.
Preferably, described discharging opening is fixed with longitudinal elevating lever, and elevating lever is provided with the locking mechanism of governor motion and the fixing dust shield relative position regulating dust shield relative altitude.
By adopting technique scheme, the airborne dust area that different whitewashing flows produce is different, whitewashing flow is more big, the pressure of corresponding source of the gas is more high, then the suction of dust shield is more big, elevating lever now can be utilized to be heightened by dust shield, can either tackle large area airborne dust, it is avoided that again and slurry lean on slurry too near suck to come in result in blockage.
Preferably, it is provided with dismountable filter screen in described dust shield.
By adopting technique scheme, dust can be retained down by filter screen, it is to avoid dust enters and causes device damage inside source of the gas.
Preferably, on described elevating lever, sliding is arranged with sliding sleeve, sliding sleeve has laterallyd secure crossbeam, crossbeam connects described dust shield by hose, hose is connected by a steam hose with the inlet scoop of source of the gas, elevating lever, sliding sleeve, crossbeam, hose constitute described governor motion, and hose is wound with spirality metal skeleton.
By adopting technique scheme, this kind of governor motion is simple and practical, easy for installation；The hose being wound with metallic framework not only has certain pliability but also have good shape retentivity, facilitate staff for airborne dust dust shield is rocked to respective angles and towards.
Preferably, threaded on sliding sleeve have lock-screw, and lock-screw constitutes described latch-up structure with sliding sleeve.
By adopting technique scheme, this kind of governor motion is simple and practical, easy for installation.
Preferably, described discharging opening is made up of two parts, and including mixing chamber and the cylindrical jet pipe of taper, the big end of mixing chamber is connected with screw rod.
By adopting technique scheme, mixing chamber pyramidal structure, bottom space is relatively big, and convenient firm slurry batch mixing out is uniform, and front end spaces diminishes, and is beneficial to formation high flow rate；Cylindrical jet pipe plays good guidance quality, it is ensured that the concordance in pulp direction.
