Specific implementation mode
A kind of dust-extraction unit of development machine, as shown in Figure 1 and Figure 2, including blast pipe 10, the stage casing of blast pipe 10 are fixed on
1 both sides of working arm are simultaneously moved with working arm 1, and wind inlet section pipeline section in free shape the hanging of blast pipe 10 is attached in milling digging head 2
Closely, the rear end of blast pipe 10 is connected with axial flow blower 20, and the air outlet of axial flow blower 20 is connected with deduster 30, and deduster 30 will
It is discharged after the air cleaning containing dust that the air inlet of blast pipe 10 sucks.Blast pipe 10 is servo-actuated with working arm 1 and enters the wind
Section pipeline section in free shape hanging is dug in milling near head 2, and this arrangement makes air inlet generate position against dust always,
Air draught is carried out in the first time that dust is spread apart not yet, makes the air containing high concentrate dust all rapidly by axis stream wind
Machine 20 sucks blast pipe, improves working efficiency.Axial flow blower 20 is arranged in the front of deduster 30 simultaneously, is conducive to axis stream wind
Machine 20 play optimum efficiency, effectively improve the air velocity of inlet scoop, make milling dig head 2 near dust within the shortest time into
Enter blast pipe 10, prevents from spreading.
In order to further increase the suction efficiency of dust, blast pipe 10 is logical at least provided with the rear end of two groups and blast pipe 10
It crosses collecting fitting interflow and enters same air duct, the leading portion of blast pipe 10 is flexible duct.Pipeline only flexible just can guarantee into
In free shape the hanging of wind section pipeline section is dug in milling near head 2, generates position against dust always, and 10 rear end of multigroup blast pipe is closed
Stream enters same air duct, can reduce the diameter of each group blast pipe 10, improve the visual range of operating personnel.
Preferably, refering to Fig. 3, Fig. 4, deduster 30 includes babinet 31, is set successively from import to export direction in babinet 31
It is equipped with nozzle 32, filter screen 33 and water conservancy diversion board group 34, the bottom of babinet 31 is connected with blow-off pipe 40.Air containing high concentrate dust
Into after deduster 30, first passes around nozzle 32 and spray water mist, a large amount of dust is filtered out by water mist, drops to the bottom of babinet 31
Portion, the air containing low concentration little particle dust continue through filter screen 33 and are filtered, after being filtered by filter screen 33
Air has been clean air, and only water content is larger, so that the air moisture after atomization is condensed into water by water conservancy diversion board group 34
To the bottom of babinet 31, the sewage of 31 bottom of babinet is flowed to by blow-off pipe 40 in conveyer drip, and mine is transported to by conveyer
On vehicle or mine conveyer.
Further, as shown in figure 5, the water conservancy diversion board group 34 is made of deflector 341 arranged in parallel,
Whole deflector 341 is in tile, and is provided with bar shaped muscle a in plate face along its length, 341 one end of deflector
It is inserted on the grid 311 of 31 bottom of babinet setting, the gap between each deflector 341 constitutes flow-guiding channel.Sky after atomization
Water droplet will be condensed into after the flow-guiding channel that air water lease making is crossed between deflector 341, flows to the bottom of babinet 31, is passing through row
Dirty pipe 40 is discharged.
In conjunction with Fig. 6, the filter screen 33 includes the outline border 331 coincideing with the section of babinet 31, and the middle part of outline border 331 is set
