Description
Technical field
The utility model relates to a kind of coal-winning machine optional feature, particularly a kind of coal mining machine control device for reducing dust.
Background technology
Coal-winning machine coal cutting be caving produce dirt be current fully-mechanized mining working main be also the dirt source point of refractory reason.In coal-winning machine contrary wind coal cutting process, coal-winning machine front roll is that weather side cylinder cuts top coal, and broken coal is caving to anterior scratch board conveyor from eminence, impacts and produces a large amount of dust.Flow to the wind leeward migration, be subject to stopping of cutting motor, dust-contained airflow climbs over cable channel and fills the air diffuse pollution driver working space, during actual measurement contrary wind coal cutting, coal-winning machine middle part, driver place dust concentration can reach 2000～5000mg/m3, the physical and mental health of serious threat underground operators and the safety in production in colliery.
Mostly current domestic Dust Control for Shearer measure be for cylinder before and after coal-winning machine, mainly comprises that coal-winning machine secondary spray of negative pressure depositing dust and dirt source follow the tracks of atomizing de-dusting, and coal cutting is caving the improvement that produces dust and mainly contains two kinds of approach for coal-winning machine.The first, side mounting dust-break curtain outside coal-winning machine front roll, stops that dust is to driver's regional diffusion; The second, nozzle is installed in coal-winning machine front roll rocking arm bottom, change the water exit position of cooling water, make its aligning be caving impact product dirt region and spray.But above two kinds of modes also have a little weak point in use procedure at the scene, and the former is fragile, and application life is short, only there is control dirt function, can not sedimentation dust; The latter's carry of spray is shorter, and fogging degree is low, cannot arrive and produce dirt region, and dust-laying effect is limited.
Utility model content
Technical problem to be solved in the utility model has been to provide a kind of novel coal-winning machine control device for reducing dust with spraying, control dirt, depositing dust, Telescopic and better effects if.
The technical solution of the utility model is as follows: a kind of coal mining machine control device for reducing dust, it is characterized in that: comprise mounting-fixing base (2), described mounting-fixing base (2) is fixed on the side of Walk Part of Shearer (1), the front end of described mounting-fixing base (2) is provided with link (3), described link (3) overcoat aerosolizing part (4), described aerosolizing part (4) is positioned at the side-lower of coal-winning machine front roll (1a), the downside of described aerosolizing part (4) and be furnished with nozzle (5) towards a side of coal-winning machine front roll (1a), described aerosolizing part (4) is provided with air inlet port or water inlet (4a), described air inlet port or water inlet (4a) are communicated with all nozzles (5) by pipeline.
Adopt technique scheme, during use, penstocks or tracheae are connected with air inlet port or the water inlet of aerosolizing part, aerosolizing part and link are fixed by latch, opening pressure water pipe and tracheae, at the downside of aerosolizing part and towards rib one side, form spraying, by regulate nozzle towards, regulate hydraulic pressure and air pressure to change spray parameter, form reasonably spraying, the spray that lower side spray forms stops that the coal cutting of coal-winning machine front roll is caving the dust that impacts generation to driver and sidewalk diffusion, the spray guiding dust that interior side spray (towards a side of coal-winning machine front roll) forms is migrated after rib one side direction.The utility model forms rational spray in the suitable region of coal-winning machine front roll side-lower, and guiding is caving impacts the dust producing along rib one lateral movement, and effectively carries out sedimentation, reduces dust-contained airflow and spreads to driver's side.When coal-winning machine is crossed termination, can and fix by latch and link aerosolizing part retraction, play flexible function.
In technique scheme: described aerosolizing part (4) is hollow strip, described aerosolizing part (4) length is 1-3m, described water inlet or air inlet port (4a) are near the left end of aerosolizing part (4), the left part of described aerosolizing part (4) is also provided with radially pin hole, and the pipeline of described connection air inlet port or water inlet (4a) and nozzle (5) is positioned at aerosolizing part (4); Described link (3) is strip, and the length of described link (3) is 1-3m, and described link (3) is upper has a radially pin hole at interval of 0.1-0.5m, and described link (3) and aerosolizing part (4) are fixed by latch.
In technique scheme: described holder (2), link (3) and aerosolizing part (4) all adopt 5-20mm steel plate to make.
In technique scheme: described holder (2) adopts the mode of bolt or welding and Walk Part of Shearer (1) to fix, described holder (2) adopts bolt to be fixed with link (3).Can be by link and holder folding point, convenient transportation, maintenance when coal-winning machine overhauls.
In technique scheme: described nozzle (5) comprises low-pressure nozzle, high pressure nozzle and the nozzle of calming the anger.
Beneficial effect: the utility model increases control device for reducing dust on coal-winning machine, integrate control dirt, dust suppression, dedusting, greatly reduce the dust concentration at coal-winning machine driver place and fuselage downwind side 10m place, total dust depositing dust efficiency is greater than 90%, and respirable dust depositing dust efficiency is greater than 80%.
