Road, the pipeline are connected with air compressor machine and jet pump respectively by threeway, and the jet pump is by jet-sub and holds spray joint
Composition, the jet-sub include high-pressure pipe, and the end of the high-pressure pipe is provided with nozzle, and the nozzle is inserted in gas collection
The centre of room, the collection chamber side are connected with air intake duct；The jet-sub is connected with holding spray joint by screw thread, described
Holding spray joint includes trunnion, and described trunnion one end is connected with the opposite side of collection chamber, and the trunnion other end is provided with anemostat, the expansion
The end of separate tube is connected with blast pipe.
Described rock drill, fume collecting chamber, air compressor machine and jet pump is designed with valve between any two.
Described fume collecting chamber is in loudspeaker barrel shape.
Connecting pipe between described air compressor machine and jet pump is as short as possible.
Described collection chamber, trunnion and anemostat is pyramidal structure pipeline.
The beneficial effects of the utility model：By application of the Bernoulli equation principle on fume extractor, lead in pipeline
Cross switch valve so that rock drilling and smoke evacuation flexible conversion, convenient and reliable, easy to operation, solve the logical of light section machine tunneling
Wind problem, avoid smog in tunnel and worker is damaged, improve speed of application.

Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
The embodiment of type is set forth in.
As depicted in figs. 1 and 2, a kind of machine tunneling fume extractor, including rock drill 4, threeway 6, air compressor machine 2, jet pump
1st, jet-sub 8, hold spray joint 9, high-pressure pipe 11, collection chamber 17 and trunnion 13, the lower section of rock drill 4 is provided with fume collecting chamber
5, be designed with pipeline 3 on the rock drill 4 and fume collecting chamber 5, the pipeline 3 by threeway 6 respectively with air compressor machine 2 and jet pump 1
It is connected, the jet pump 1 is made up of jet-sub 8 with spray joint 9 is held, and the jet-sub 8 includes high-pressure pipe 11, institute
The end for stating high-pressure pipe 11 is provided with nozzle 12, and the nozzle 12 is inserted in the centre of collection chamber 17, the side of collection chamber 17
It is connected with air intake duct 16；The jet-sub 8 is connected with holding spray joint 9 by screw thread, and the spray joint 9 that holds includes trunnion
13, described one end of trunnion 13 is connected with the opposite side of collection chamber 17, and the other end of trunnion 13 is provided with anemostat 14, the anemostat 14
End be connected with blast pipe 15.
Described rock drill 4, fume collecting chamber 5, air compressor machine 2 and jet pump 1 is designed with valve 7 between any two.
Described fume collecting chamber 5 is in loudspeaker barrel shape.
Connecting pipe 3 between described air compressor machine 2 and jet pump 1 is as short as possible.
Described collection chamber 17, trunnion 13 and anemostat 14 is pyramidal structure pipeline.
During utility model works, when rock drilling finishes, breeching explosion after, Open valve A71, valve B72, valve C73, close
Valve closing door 7 and valve D74, the compressed air of air compressor machine 2 is sent into nozzle 12 through high pressure admission, 11, because the inner chamber of nozzle 12 is taper,
Outlet Section is gradually reduced, and compressed air injects anemostat 14 with high speed through collection chamber 17, trunnion 13, when spouting velocity is very big
When, outlet pressure greatly reduces, while brings the gas of near exit into anemostat 14 by the air-flow that nozzle 12 sprays, and makes spray
Pressure subatmospheric power near nozzle 12, negative pressuren zone is formed, smog enters through fume collecting chamber 5, pipeline 3 and air intake duct 16 in tunnel
Collection chamber 17, high velocity air are mixed with the smog sucked in collection chamber 17, and energy transmission or exchange are carried out in collection chamber 17,
High-speed compressed air loses energy, and low speed smog obtains energy, and last both reach similar flow velocity, together into trunnion 13,
In trunnion 13, mixed airflow forms stable flow regime, after air-flow enters anemostat 14 by trunnion 13, flows decrease, and pressure
Power raises, and is discharged through blast pipe 15；Valve A71, valve B72, valve C73 are closed, opens valve 7 and valve D74, you can is carried out
Rock drilling works.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
