The purpose of this utility model is achieved through the following technical solutions:
A kind of coal mine pressure wind applies dust-proof anti-spray orifice fireproof multi-function device in brill, including dust cover, in the dust cover
Outer wall be equipped with draw gas pumping pipe and investigation the mouth of a river；Baffle is installed on one end of the dust cover, dust cover it is another
End is opening；Sleeve runs through the dust cover and baffle, and is fixedly connected with the dust cover and baffle；
One annular spray line setting at front end, is equipped with multiple nozzles inside the dust cover on annular spray line
One；One end of one vertical spray line is located in the dust cover, and the other end extends to outside the dust cover, in the vertical sprinkling
Pipe is located at one end in the dust cover and is equipped with nozzle two.
Further, which is mounted on the drilling rod of drilling machine front end.
Further, the annular sprinkling extends to outside the dust cover and is connected with a quick coupling.
Further, the vertical spray line is located at one end outside the dust cover and is connected with the annular spray line, and
It is connected in the quick coupling.
Further, it is described draw gas pumping pipe, investigation the mouth of a river be connected with the dust cover.
By adopting the above-described technical solution, the utility model has the advantage that
The utility model has dust-proof, anti-spray orifice, fireproof function, optimizes safe space, ensure that security context.This
Utility model dust-laying effect is good, substantially improves the security context for applying the scene of boring and return air streaming system, ensure that the work of worker
Meet regulation as environment, legal conjunction rule production guarantees the physical and mental health of worker.The utility model can also effectively prevent applying drill-through
Journey spray orifice is hurted sb.'s feelings, and can will be applied the gas sprayed during brill in time and be taken away, be effectively reduced and apply brill scene and return gas density,
Prevent and avoid applying to bore spray orifice massive gas is caused to transfinite accident.Meanwhile drilling rod, drill bit can be effectively prevented in the utility model
Friction kindling is overflowed from aperture.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the left view of the utility model Fig. 1；
Fig. 3 is the right view of the utility model Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Referring to Figure 1~3, the utility model provides a kind of coal mine pressure wind to apply dust-proof anti-spray orifice fireproof in brill multi-functional
Device can solve existing pressure wind and apply brill existing dust be big, environment is poor, easily produces fire by friction and causes fire incident, working efficiency
Problem low, occupational disease is multiple.
The utility model includes dust cover 1, is equipped on the outer wall of dust cover 1 and draws gas pumping pipe 2 and the investigation mouth of a river 3, draws
Gas pumping pipe 2, the investigation mouth of a river 3 are connected with dust cover 1.
Baffle 4 is installed on one end of dust cover 1, sleeve 6 runs through dust cover 1 and baffle 4, and with dust cover 1 and
Baffle 4 is fixedly connected.Casing 6 can be fixed on dust cover 1 and baffle 4 by welding manner, can be welded on casing 6 more
Casing 6 is welded on dust cover 1 by a fixed link 5 by fixed link 5.
The one annular setting of spray line 7 at front end, is equipped with multiple nozzles inside dust cover 1 on annular spray line 7
One 8.Annular spray line 7 extends to outside dust cover 1 and is connected with a quick coupling 11.One end of one vertical spray line 9 is located at
In dust cover 1, the other end is extended to outside dust cover 1, is located on one end in dust cover 1 in vertical spray line 9 and is equipped with nozzle two
10, vertical spray line 9 is located at one end outside dust cover 1 and is connected with annular spray line 7, and is connected in quick coupling 11.
When specifically used, by 6 sets of casing on the drilling rod of drilling machine front end, drilling rod enters from casing 6 close to one end of baffle 4
Casing 6, and stretched out from casing 6.Behind the fixed dip angle of hole orientation of aperture, and dust cover 1 is fixed at the top of tunnel, casing 6
Put in aperture.Quick coupling 11 is connected with water inlet pipe high pressure connection and opens gate valve water inlet, starts drilling machine, dust is anti-in drilling
Wind effect is lower to enter dust cover 1, is gone out dirt by nozzle 1 and the water spray of nozzle 2 10.Dust is excluded by the deslagging mouth of a river 3, is reached
Dust-laying effect.
It smolders, can also be sprayed water by nozzle 1 and nozzle 2 10 if there is borehole friction is on fire in drilling process,
