Just the concrete operating principle of the air-transport system of the present invention is described in detail below：
The present invention point dry and wet Liang Zhongsao roads pattern.Swept in dry type under the pattern of road, the negative pressure and blowback air duct 41 in dustbin 1 go out
Pavement garbage below the blowback direct draught come, suction nozzle is collected to the right from left side to be entered in dustbin 1 by main suction tube 42, greatly
Particle rubbish is deposited on the bottom plate of dustbin 1 under gravity, and remaining little particle continues to pass sequentially through filter under airflow function
Net 111, the inner chamber of coarse filtration guard 11 enter the inner chamber of outer barrel 121, are acted in the centrifugation eddy airstream produced by centrifugal dust-removing cylinder 12
Under, most crude particle dust is in 12 bottoms of centrifugal dust-removing cylinder, and remaining passes sequentially through inner cylinder 122, transition air channel 14 and entered
Air channel 21 enters inside blower fan 2, with the rotation of the impeller of blower fan 2, enters exhausting duct 3 with the air-flow of fine sand dirt.Exhausting duct 3 this
When state open for the part of blowback air-flow plate 31（There is an intersegmental gap from side seal board 34）, dry and wet switch boards 32 are in level
Position, so enters the air-flow of exhausting duct 3, partly enters inlet/outlet C, then enters suction nozzle 4 by flexible pipe 53, blowback air duct 41, its
Remaining to enter the first disposal box 15 by exporting A, when air-flow is by filter cylinder 52, particle therein can be adsorbed on filter cylinder 52, and is remained
Under cleaned air can by the filter material hole on filter cylinder 52, exhaust outlet 18 enter air in.Per after a while, air valve 51 is vibrated
Meeting jet, the dust on filter cylinder surface is blown off in dust cone cylinder 142；Treat that the dust in dust cone cylinder 142 is accumulated to a certain extent,
Normally closed dedusting switch boards 161 can be opened, and dust will pass sequentially through switching air channel 16, the second suction pipe in the presence of air-flow
18 are blown in dustbin 1, and then dedusting switch boards 161 can be closed again.
Swept in wet type under the pattern of road, the blowback direct draught that the negative pressure and blowback air duct 41 in dustbin 1 come out, under suction nozzle
The pavement garbage of side is collected to the right from left side to be entered in dustbin 1 by main suction tube 42, and bulky grain rubbish is under gravity
It is deposited on the bottom plate of dustbin 1, remaining little particle continues to pass sequentially through filter screen 111, the inner chamber of coarse filtration guard 11 under airflow function
Into the inner chamber of outer barrel 121, under the centrifugation eddy airstream effect produced by centrifugal dust-removing cylinder 12, most crude particle dust
In 12 bottoms of centrifugal dust-removing cylinder, remaining passes sequentially through inner cylinder 122, transition air channel 14 and air inlet duct 21 and entered inside blower fan 2, with
The rotation of the impeller of blower fan 2, enters exhausting duct 3 with the air-flow of fine sand dirt.The state of exhausting duct 3 now is blowback air-flow plate
31 parts are opened（There is an intersegmental gap from side seal board 34）, the edge of dry and wet switch boards 32 withstands on the base of top plate 33, so enters and arrange
The air-flow in air channel 3, partly enters inlet/outlet C, then enters suction nozzle 4 by flexible pipe 53, blowback air duct 41, and remaining is direct by exporting B
It is discharged into air.During due to wet operation, the humidity in granulated garbage air-flow is larger, and most rubbish and sand and dust can be settled
In the dustbin 1 or the bottom of the second disposal box 17, the air-flow being discharged in air hardly includes dust.
The present invention uses above technical scheme, is not limited by region and weather so that sweeping machine can be in all weathers, the north
Icing, which is snowed, carries out operation under the various weathers such as season, improves the utilization rate of vehicle, reduces airborne dust.
