The schematic diagram of first state, Fig. 7 when Fig. 6 is the road cleaner discharging of present pre-ferred embodiments
The schematic diagram of the second state, refers to Fig. 6 when being the road cleaner discharging of present pre-ferred embodiments
And Fig. 7, wherein, first state refers to the state after dustbin 130 is lifted when dumping rubbish 200,
Second state refers to the state of return again after dustbin 130 is lifted.Road cleaner also includes discharging
When hydraulic system (such as elevating ram, not shown), hydraulic system be used for lift dustbin 130
And the control return of dustbin 130.Specifically, road cleaner dump rubbish 200 when, first,
Please join Fig. 6, using elevating ram lifting dustbin 130 and while contraction dust cover 160；Open discharging
Gate 132, interim feed bin 150 is poured into by rubbish 200 from discharge port 131, now discharging wicket 151
It is closed；Then, Fig. 7 please be join, elevating ram shrinks to be made the return of dustbin 130 and simultaneously will
Dust cover 160 launch with ground formed certain interval, after the return of dustbin 130, blower fan 110 with remove
Dirt device 120 is connected；Start blower fan 110, simultaneously close off the suction inlet valve 141 in sweep-up pipe 140b,
So as to form independent between blower fan 110, dust arrester 120 and dust cover 160 in compartment 103
Air channel (as shown by arrows in FIG.), now, opens discharging wicket 151, by rubbish 200 from interim material
Storehouse 150 is poured into dust cover 160.Due to the closing of suction inlet valve 141, the blower fan of road cleaner
The negative pressure produced during 110 operating can be transferred to the gap location of dust cover 160 and ground surrounding, dust cover
160 dusts that will be fallen are intercepted, even if some dust is escaped out, also can again be sucked by negative pressure
Dust arrester 120 is filtered, the purpose of airborne dust when suppressing road cleaner discharging so as to reach.When clear
Sweep road dust amount it is larger when, can suitably select to improve the rotating speed of blower fan 110 during discharging, i.e., can be with
Rotating speed in discharging to blower fan 110 is adjusted.
The beneficial effects of the invention are as follows by increasing interim feed bin 150, lifting rubbish on road cleaner
Discharging gate 132 is first opened after rubbish case 130, rubbish is poured into interim feed bin 150, interim feed bin 150
Play a part of terminal, then by the return of dustbin 130, open blower fan 110 and open discharging wicket
151, the dust that the negative pressure produced by blower fan 110 is produced when catching and dumping rubbish 200.Road cleaning
Car anhydrous operation in discharge process, it is to avoid the adverse effect that climatic factor is brought, and can effectively suppress
Airborne dust during discharging, dust-laying effect is good.
The road cleaner with discharging dust-arrest device provided by the present invention and control method are entered above
Go and be discussed in detail, specific case used herein has been carried out to principle of the invention and implementation method
Illustrate, the explanation of above example is only intended to help and understands the method for the present invention and its core concept；
