The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Referring to Fig. 1, Fig. 2 and Fig. 8.The utility model is to convert on the basis of typing automobile chassis 3 (containing engine 1 and driver's cabin 2).The dust suction flow process is seen shown in Fig. 1 arrow, road surface dustiness and part spray water are through suction port 11 and sweep-up pipe 48,63, enter dustbin 4, air behind depositing dust, the water from the air intlet 5 at dustbin top through air intake passage 6, blower fan import 7, blower fan 8, blower fan exit passageway 9, back blows out from blowpipe 49 and mouthpiece 12, is directed at that noise disturbs residents greatly and seriously and the driver when inhaling the dirty operation of the dusty complexion of sweeping the floor.Improvement of the present utility model is in air intake passage and blower fan exit passageway silencer 10 to be housed all, has obtained tangible noise elimination effect.

Two pilot instruments 13.The driver cleans the right side curb for convenience, inhales comprehensively and has swept whole road surface, except the left handle drive device of existing automobile, also should possess right-hand drive, promptly two pilot instruments.Like this, just can inhale comprehensively and sweep, and make more convenient operation road.

Fig. 3 represents the oil circuit figure of two oil circuits.Prior art is that the transmission with oil circuit device is that the driving of oil pump is received on the assistant engine 14 (also referring to Fig. 1 .2), operation is swept in i.e. suction and the discharge operation of the case of dumping rubbish drives by assistant engine, so that when dumping rubbish, blower fan is ceaselessly running still, causes waste.When assistant engine broke down, rubbish can not be toppled over, and made troubles for cleaning work and maintenance.The utility model is that dump rubbish case oil cylinder and keying back door oil cylinder are separated with other oil circuit, the oil pump 21 of promptly toppling over dustbin oil cylinder 15 and back door keying oil cylinder 16 is connected on the engine 1, the limit brush is promoted (being that limit brush axle half-twist is seen Fig. 2) oil cylinder 17, suction port lift cylinder 18, the oil pump 22 that main brush (being that round brush 62 is seen Fig. 1) corner is adjusted oil cylinder 19 and main brush lift cylinder 20 is connected on the assistant engine 14, and blower fan is to see Fig. 1 and Fig. 2 by assistant engine through what belt transmission 23 drove.Like this, ato unit 1 and close assistant engine 14 when dumping rubbish, blower fan shuts down; When assistant engine breaks down, can not influence and dump rubbish.

Fig. 4 represents residual water blowing-down device.Watering in the cleaning work is that water pump 27 absorbs water from water tank 24, through pipeline 25 and filter 26, improves hydraulic pressure after pipeline gushes out from the nozzle 28 that is distributed in each position finishes, and nozzle is located at main brush, limit brush, suction port etc. and locates.Winter, the weather is cold and the ground is frozen, can freeze nozzle and pipeline when termination of pumping and after the operation that stops to sprinkle water even freezing.Water can't spray when opening watering device once more.The utility model adopts the pipeline 30 that is communicated with from Vehicular compressed air jar 29 on the pipeline behind the pump discharge.Close pipe valve 33 and open pipe valve 31 after termination of pumping, the water that compressed air will remain in pipeline and the nozzle blows down clean.Close pipe valve 32 again, open pipe valve 34, make compressed air from the pump discharge blowback, so that residual water in pump, filter and the inlet channel is blown off.Termination of pumping and stop watering after, can guarantee pump, each inlet and outlet pipe lines and nozzle is unlikely freezes.

Fig. 1 and Fig. 8 represent the two back-blowing devices of self-circulation type.By noted earlier, the spray water of the dirty and part of suction port 11 inlet passage dusty complexions and behind the depositing dust of dustbin, water, air is through blower fan import and outlet, blow to the road surface from mouthpiece 12, can further blow afloat the dustiness on the road surface, sweep totally in order to the suction port suction, sweep efficient with the raising suction thereby reduce the discharging dustiness.

Fig. 5-Fig. 7 represents to pour out the back door forced locking device of rubbish.Be hinged with pitman shaft 35 on the back door 42, the pitman shaft middle part is fixedly connected with support arm 43, the tailpiece of the piston rod of support arm 43 1 ends and back door keying oil cylinder 16 is hinged, the pitman shaft two ends are fixedly connected with pivoted arm 36, the hinged outside plate 37 of pivoted arm, outside plate hypomere band wedge shape, outside plate inserts in the latch 38 back door is pinned, and lock is tight more more along with constantly inserting down.The outside plate hinged inside has inner panel 39, and the hypomere of inner panel is hinged with the axis of guide 40, and after outside plate inserted latch, the axis of guide of inner panel slided up and down along guide hook 41 formed vertical grooves, thereby guarantees that outside plate inserts in the latch reliably.

Fig. 8 represents the sweep-up pipe floating installation.Suction port 11 and mouthpiece 12 both sides and back are surrounded by abrasive rubber baffle plate 44, there is support wheel 45 at the rear, the place ahead is hung on the chassis auxiliary girder 47 by steel wire rope 46 and lift cylinder 18, the top is hung on the float plate 50 by sweep-up pipe 48 and 49 of blowpipes, float plate is supported on the spring 53 in the spring base 52 by pogo barrel 51, spring base is fixedly connected on the auxiliary girder of chassis, has guaranteed that sweep-up pipe (together with mouthpiece) is in quick condition.The effect of this floating installation is: when being reset on the float plate 50 after sweep-up pipe 63 is dumped rubbish in company with dustbin 4, can guarantee that sweep-up pipe 48 is by the sealing between float plate 50 and the sweep-up pipe 63, the particularly unavoidable mountain peak ripple and the sealing of state such as rocking during normal operation is to reach good pick-up performance.

Fig. 9 represents limit brush collision prevention device.When the rotation limit of cleaning work brush 54 bump to hinder when thing or roadside curb, can influence cleaning work or damage the limit brush.The utility model is provided with collision prevention device, and support arm 55 is fixed on the chassis, at the flip-arm 56 of support arm 55 and the junction of swing arm 57 hinging pin shaft 58 is arranged, and there is extension spring 59 at parallel place with swing arm.Dust collecting and cleaning vehicles advance forward limit brush bump to hinder when thing or roadside curb, limit brush and swing arm meeting are rotated around bearing pin 58, treat by after, by extension spring 59 pulling force swing arm is returned to together with the limit brush and resets, the limit brush is by hydraulic motor 60 drivings.When needs promote the limit brush and are about to 90 ° of limit brush axle upsets, be to drive flip-arm half-twist (see figure 2)s by upset (liftings) cylinder 17, limit brush contacting like this with regard to disengaging and ground.

Foul water tank 61 is arranged under Fig. 1 dustbin, and after the watering, the part water droplet can be inhaled into dustbin together with the ground dust and dirt, and sewage can be poured down or forth full ground from the back door in the dumping process, brings new pollution.After the utility model was set up foul water tank, sewage retained in the foul water tank, and toppled over respectively with rubbish, made that to dump rubbish more convenient.

The utility model contrast prior art has following advantage: noise was low when operation was swept in suction; Can be convenient and comprehensively with the road Face is inhaled and is swept totally; Can avoid prior art opening the disadvantage that blower fan is dumped rubbish; Shut down and rear unlikely the freezing that stop to sprinkle water Water pipe and nozzle; But back door auto lock; Unlikely being damaged of limit brush; The unlikely secondary pollution that causes sewage.
