Enter the entrance 81 of nozzle 80, and be used as high-speed flow（Indicated in Fig. 4 by shown B）It is discharged into out from the outlet 83 of nozzle
Mouth pipe 82.High speed into the air-flow of outlet 82 can guide upper air current amount in outlet 82.This can be further
Cause to produce vacuum in inlet tube 54 and at the first end 60 of intermediate tube 58.
When machine 10 performs milling process above road surface 14, ventilating system 52 can be used for collecting in milling system 26
The dust and smog produced at milling roller 28.Initial pressure in inlet tube 54, intermediate tube 58 and outlet 82 is P1.Ventilation
System 52 receives forced air by air inlet pipe 72 from compressor 25.Forced air is filled in the doughnut 64 of intermediate tube 58
It is internal.Then, forced air discharges from doughnut 64, enters outlet 82 by multiple nozzles 80.Discharge multiple nozzles 80
The speed of air-flow due to the phenomenon that referred to as " throttles " in the volume of outlet 82 it is very high.Pressure in the volume of outlet 82
P1 is changed to above the pressure P2 of initial pressure P1, but the pressure in the volume of inlet tube 54 and intermediate tube 58 keeps " P1.This leads
Cause to produce pressure differential in the different zones of ventilating system 52.The pressure differential of pressure P1 and P2 in ventilating system 52 are in inlet tube 54
Place produces vacuum effectiveness.Therefore, the dust and smog produced at milling roller 28 is inhaled into（Indicated in Fig. 4 by shown C）
And it is sent to the secondary conveyer 40 in housing 50.
Industrial applicibility
The disclosed ventilating system 52 of the present embodiment can be used for removing during milling process by the cold milling on road surface 14
The dust and smog that planer 10 produces.Ventilating system 52 produces vacuum by the forced air at inlet tube 54.Specifically, it is more
A nozzle 80 guides compressed air to outlet 82 from compressor 25, makes dust and smog to produce vacuum at inlet tube 54
Discharged from outlet 82.Vacuum is produced by using forced air and nozzle 80, the utility model is eliminated for removing dedusting
The use of the fan of dirt and smog.In addition, the present embodiment eliminates the use of fan, less space is occupied, is which thereby enhanced
The durability and reliability of the ventilating system 52 of machine 10.This also contribute to while machine 10 are operated improve operator can
Depending on property.In addition, the utility model provides the ventilating system 52 of easily installation and the smaller of tool energy efficiency.
Although specifically illustrated with reference to above-described embodiment and describe the aspect of the utility model, art technology
