Description
Technical field
The present invention relates to coal mine equipment field, especially a kind of automatic hydraulic bracket moves frame dust-extraction unit.
Background technique
Coal face drop column move frame when dust-producing amount it is quite big, be the main dust point of coal face, because condition compared with
Get up for specially treated relatively difficult；The preceding top beam of coal face hydraulic support does not have side guard plate protection, when dropping column shifting frame
Gap between two brackets is between 80-120mm, and a large amount of coals fall to form the waterfall to descend slowly and lightly from gap when moving frame,
The top of gap region is coal breakage face, and wherein coal dust waves with distinguished and admirable in working face, seriously affects the body of operator
Body health has just been moved frame coal breakage dirt in the drop column to hydraulic support since having coalcutter and is handled, but because not preferable
Processing method, which is only dropped at it, carries out single atomizing de-dusting processing when column moves frame, be commonly downward spraying and its coal breakage side by spraying
To roughly the same, work can not be caught at all to coal breakage impact dirt, the dust that can be caught is limited, so dust-laying effect is unobvious.
Summary of the invention
In view of the problems of the existing technology, it can effectively be captured in hydraulic support the purpose of the present invention is to provide a kind of
Drop when column moves frame that coal breakage dust, automatic hydraulic bracket move frame dust-extraction unit at gap between two stands, to achieve the goals above,
The technical solution adopted by the present invention are as follows:
A kind of automatic hydraulic bracket moves frame dust-extraction unit, comprising: fixing seat is provided through groove in the fixing seat；
Connect coal slot support, it is described connect coal slot support be slidably disposed in the groove；Coal slot is connect, the coal slot that connects can automatic turning
Be connected to it is described connect in the support of coal slot, described connect is provided with spray pipe on coal slot, direction is provided on the spray pipe
The anti-blocking fog-spray nozzle in coal breakage face；Oil cylinder support base, is provided with oil cylinder support base in the middle part of the fixing seat, on the oil cylinder support base
It is provided with the oil cylinder that can be stretched out to the groove left and right ends, the oil cylinder connects coal with described far from oil cylinder support base one end
Slot support connection.This dust-extraction unit work principle, when column drops in hydraulic support, because of the oil cylinder and bracket upright post oil cylinder of this dust-extraction unit
Pipeline series connection.So in dust-extraction unit connect coal slot from trend both sides stretch out be placed under two stands gap, automatically turn on simultaneously
Anti-blocking fog-spray nozzle is spraying to its gap, makes at its gap and cradle top is full of pressure fog, act on small script in pressure fog
The tiny coal dust being adsorbed on coal grain is wet sedimentation, is just settled down when coal breakage dust is spread not yet, makes it not
It can be there is a phenomenon where floating in the air everywhere, while falling to and being connect in coal slot after coal breakage dust and water mixing, it avoids falling everywhere, be not easy clear
Reason.When hydraulic moving stand completion bracket upright post extends upwards withstands coal top, because of dust-extraction unit cylinder pipe and bracket oil cylinder
Pipeline is to be arranged in series, so dust-extraction unit, which connects coal slot and automatically retracts under the action of oil cylinder, is attributed to home below bracket,
Complete an automatic dust removing process.
Preferably, the oil cylinder support base has glissile segment and supporting section, and the glissile segment slides in the groove.Institute
It states and connects coal slot and be hinged on the supporting section by rotation axis, also there is spring, connect coal slot described in the spring one end connection, one
End connects the supporting section, and described connect is provided with limit inclined-plane with the supporting section hinged place on coal slot, described to connect coal slot and institute
It states and is provided with limit base below supporting section hinged place.After the coal breakage dust for being mixed with water calls in described connect in coal slot, work as weight
More than spring pulling force when, the coal slot that connects will be rotated down around the rotation axis, when the limit contact of incline plane is described in
It when limit base, stops operating, coal breakage dust enters chute and together with other coals along coal geosynclinal synclinorium sliding underneath is connect at this time
It is slipped away by chute, is not necessarily to manual cleaning, the sprinkling direction of the anti-blocking fog-spray nozzle described at this time is oblique top, can be sprayed bigger
Region catches its coal dust constantly during the falling process, after coal breakage dust slides, when connecing coal slot decline coal dust weight
When less than being more than the pulling force of spring, horizontal position will be rotated back to upwards by supporting point of rotation axis by connecing coal slot under the effect of elasticity
It sets；It works repeatedly and realizes the depositing dust processing of coal breakage.Simultaneously because when connecing coal slot in the rotation axis rotation process, institute
The water for stating anti-blocking fog-spray nozzle sprinkling can be more evenly sprinkled upon on coal breakage face, can more effectively prevent descending slowly and lightly for coal breakage dust.
Preferably, described to connect coal slot described supporting section one end is provided with atomizing inlet interface, facilitate water supply, it is described anti-
Stifled fog-spray nozzle is along spray pipe length direction setting no less than 3, and the anti-blocking fog-spray nozzle spray direction is perpendicular to described
It is upward to connect coal slot, can preferably cover coal breakage face, prevent coal breakage dust from floating in the air everywhere.
Preferably, be provided with protruding portion on the glissile segment, the oil cylinder far from oil cylinder support base one end with it is described
Protruding portion connection.By pushing the protruding portion, to facilitate the left-right position for connecing coal slot described in adjustment.
The beneficial effects of the present invention are:
In the work of this dust-extraction unit, the coal ash on coal breakage face falls the anti-blocking fog-spray nozzle of the foregoing description i.e. to coal breakage downwards
Face starts to spray water, and is just settled down when coal breakage dust is spread not yet, so that it will not there is a phenomenon where floating in the air everywhere, together
When coal breakage dust and water mixing after fall to and connect in coal slot, avoid falling everywhere, be not easily cleaned.Meanwhile the oil cylinder support base
On be provided with can to the groove left and right ends stretch out oil cylinder, oil cylinder can push connects coal slot stretching, retract.Adjustment is facilitated to connect
The position of coal slot, the position in Lai Yinghe coal breakage face.
