Description
Technical field
The utility model relates to a kind of automatic fully-mechanized digging machine high pressure external spraying device for reducing dust, is used for getting working face is carried out the automatic high pressure atomizing de-dusting.
Background technology
At present, adopt common dust prevention at the fully mechanized workface in each colliery, because hydraulic pressure is greatly less than certain pressure, although certain dust-proof effect is arranged,, dust-proof effect is all very undesirable, does not far reach the dustproof standard of country.Moreover, when the fully-mechanized digging machine group turns round, dustproof pipeline spray for dust suppression, when the fully-mechanized digging machine group stopped, dustproof facilities must artificially be turned off valve also at spray for dust suppression, can not realize the automatically purpose of control.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of defects that solved is provided, can carry out the automatic high pressure atomizing de-dusting to getting working face, make the dust of coal-face be reduced to MIN automatic fully-mechanized digging machine high pressure external spraying device for reducing dust.
The technical scheme that its technical problem that solves the utility model adopts is: described automatic fully-mechanized digging machine high pressure external spraying device for reducing dust, comprise fully-mechanized digging machine group and starting switch, one side of fully-mechanized digging machine group is connected with the cutter cylinder by support, starting switch is connected by load cable with the fully-mechanized digging machine group, it is characterized in that: be socketed with the stainless steel jet head sets on the support, the stainless steel jet head sets is connected with the delivery port of spraying electrical ball valve, the water inlet of spraying electrical ball valve is connected with high-pressure hydraulic pump, high-pressure hydraulic pump is positioned at Automatic water tank, be provided with equipment on/off transducer on the load cable, equipment on/off transducer is connected with the spraying electrical ball valve behind main controller and relay.
Between the delivery port of described stainless steel jet head sets and spraying electrical ball valve, between water inlet and the high-pressure hydraulic pump of spraying electrical ball valve all the high-pressure rubber pipe by Φ 10 be connected.
When the fully-mechanized digging machine group starts running, the load cable that links to each other between starting switch and the fully-mechanized digging machine group has electric current to pass through, electric current by the time electromagnetic induction that produces gathered by equipment on/off transducer, the signal that equipment on/off transducer collects becomes a switching signal after shaping, amplification, amplify to main controller by cable transmission, differentiate and relatively after the direct control relay work of signal, drive the spraying electrical ball valve, by the spraying of stainless steel jet head sets, thereby realize that automatically control is sprayed or the overall process of watering.
When the fully-mechanized digging machine group shuts down, no current flows in the load cable, can not produce electromagnetic induction yet, equipment on/off transducer does not collect induced signal, normal opened contact disconnects, and main controller does not receive signal, relay by normal battle closure be converted to and disconnect normal battle, spraying electrical ball valve dead electricity and autoshutdown, spraying stops.
Utilize high-pressure pump 8-10Mpa water under high pressure, be transported to the stainless steel jet head sets that is fixed on the cutter cylinder by high-pressure rubber pipe, form thus highly dense (10
