Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
The mining-drilling machine of the embodiment of the present invention and its dust-extraction unit described below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram for the mining-drilling machine for including dust-extraction unit.
As shown in Figure 1, the mining-drilling machine of the embodiment of the present invention, including drilling machine gyrator 1, drilling rod 2 and support drilling machine ontology
Stent 3.Wherein, drilling machine gyrator 1 can drive drilling rod 2 to creep into carry out work of drilling in the running.
As shown in Figure 1, the dust-extraction unit of the mining-drilling machine of the embodiment of the present invention may include dust gathering arrester 10, cyclone dust collectors 20
With exhaust fan 30.
Wherein, dust gathering arrester 10 corresponds to drilling rod 2 and sets；The air inlet of cyclone dust collectors 20 passes through dust removal pipe 40 and dust gathering arrester
10 are connected；The inlet scoop of exhaust fan 30 is connected by dust removal pipe 40 with the air outlet of cyclone dust collectors 20, exhaust fan 30
Power connector is carried out by transmission mechanism 50 and drilling machine gyrator 1.When mining-drilling machine starts work, drilling machine gyrator 1 is being transported
Exhaust fan 30 can be driven to operate when turning, drilling rod 2 at dust gathering arrester 10 is crept into generated dust laden air is evacuated to cyclone dust collectors
It is dusted in 20, and the air after dedusting is evacuated to exhaust fan 30 will pass through the discharge of the exhaust outlet of exhaust fan 30.
In one embodiment of the invention, transmission mechanism 50 may include conveyer belt or gear.
Illustrate the course of work of dust-extraction unit so that transmission mechanism 50 is including conveyer belt as an example below.Referring to Figures 1 and 2,
Start in mining-drilling machine and to during coal wall internal drilling operation, drilling machine gyrator 1 can also pass through while operating drives drilling rod 2
Conveyer belt 51 drives the wind wheel 31 in exhaust fan 30 to rotate, and it can be that cyclone dust collectors 20 provide that wind wheel 31, which rotates generated negative pressure,
Flow rotation power, negative pressure are transferred to the dust laden air at smokable hell at dust gathering arrester 10.When dust laden air enters whirlwind
During deduster 20, air-flow will become circular motion from linear motion, you can form swirling eddy.Most edges of swirling eddy
The wall of cyclone dust collectors 20 is twist downward, cones towards cyclone dust collectors 20 flow.Dusty gas is in rotary course
Centrifugal force is generated, the grit that severe is more than to gas is got rid of to wall.Grit is once contacted with wall, just lose inertia force and lean on into
The momentum and downward gravity of mouth speed fall along wall surface, into the ash releasing tube of cyclone dust collectors 20.Twist downwards
Swirling eddy when reaching cone, drawn close due to the contraction of cone-shaped to 20 center of cyclone dust collectors.When swirling eddy reaches
During a certain position in cone lower end, you can with same direction of rotation from 20 middle part of cyclone dust collectors, by lower reversion on, continue to make
Helical flow, and the air outlet through cyclone dust collectors 20 enters exhaust fan 30, the finally exhaust outlet discharge through exhaust fan 30.

Motor obtains power, i.e. exhaust fan 30 can be operated using any power source existing on mining-drilling machine, without introducing volume
Outer power source, so as to reach above-mentioned advantageous effect.
The above-mentioned process being dusted by cyclone dust collectors can effectively remove big grain size dust in dust laden air (such as
Diameter is more than 5 μm of coal dust), the respirable dust of part small particle is actually further included in dust laden air, and (such as diameter is small
In 5 μm of dust).To effectively remove the respirable dust, in one embodiment of the invention, as depicted in figs. 1 and 2, remove
Dirt device may also include dedusting strainer 60, and dedusting strainer 60 may be provided at the exhaust outlet of exhaust fan 30, and dedusting strainer 60 can be used
It is filtered in the air of the exhaust outlet discharge to exhaust fan 30.
As a result, in the sky that after the secondary purification of the first class purification of cyclone dust collectors and dedusting strainer, can will be fully cleaned up
Gas is discharged, and dust removing effects are preferable.
Further, as shown in figure 3, the dust-extraction unit of the mining-drilling machine of the embodiment of the present invention may also include gearbox 70.
The input shaft of gearbox 70 can (including such as conveyer belt and gear etc., be to include conveyer belt 51 in Fig. 3 by transmission mechanism
Example) and the progress power connector of drilling machine gyrator 1, the output shaft of gearbox 70 can be with the progress power connector of exhaust fan 30, gearbox
70 can be used for adjusting the rotating speed of exhaust fan 30.By adjusting the rotating speed of exhaust fan 30, different size of negative pressure and pumping can be generated
Wind air quantity, consequently facilitating the amount of dust according to caused by drilling changes except dust quantity.It should be appreciated that since drilling machine gyrator 1 is
Drilling rod 2 to be driven to creep into carry out work of drilling, when drill work, the rotating speed of drilling machine gyrator 1 is usually root
It is adjusted according to the speed demand or drilling dynamics demand of drilling rod, and is unsuitable for being adjusted according to the demand except dust quantity.
In consideration of it, by gearbox 70 of the setting with multiple gears, when gearbox 70 switches to different gears, pumping can be changed
The rotating speed of wind turbine 30, so as to adjust except dust quantity.As a result, by setting gearbox 70 in dust-extraction unit, can make of the invention real
