(2) background technology
Along with the progress of society, quickening of urbanization process, the increasing of urban population, urban road extends in continuous expansion, and communal facilities is constantly newly-built, and the rubbish output increases sharply, so the method for hand sweeping road can not satisfy the requirement of situation far away.Because pavement cleaning vehicle can improve the environmental sanitation level greatly, reduce cleaner's labour intensity, so pavement cleaning vehicle has obtained significant progress.At present, the development of pavement cleaning vehicle mainly is a both direction: the one, and the dust-absorption sweeping type road-sweeper, also having one is the pure sweeping road-sweeper.
Dust-absorption sweeping type road-sweeper structure is by chassis, assistant engine, blower fan, dustbin, water tank, side panel brush, horizontal columns brush, suction inlet and air outlet etc. are formed voluntarily.Assistant engine, blower fan are positioned at driver's cabin rear, chassis, generally connect by fluid coupling or dry friction clutch.The dustbin of volume maximum is positioned at the chassis postmedian, and its rear portion and vehicle frame are hinged, and a tipping hydraulic cylinder is arranged at front portion or bottom, is hinged between dustbin and the vehicle frame.Water tank can be made of one with dustbin, is positioned at the dustbin bottom, or is fixed in dustbin below or other position as an individual components.The side panel brush is fixed on both sides, vehicle frame middle part.Horizontal columns brush is positioned at the vehicle frame below, can be left or right avertence change certain angle, do to cooperate left hand plate brush or right side dish dataller.Suction inlet is positioned at the position after a while of side panel brush and horizontal columns brush.The dust-absorption sweeping type road-sweeper is when work, at first select left side or right side operating type, corresponding side panel brush and horizontal columns brush are placed duty by the operating type requirement, side panel brush and horizontal columns brush coordinating operation in the road-sweeper traveling process, the horizontal impelling of rubbish to suction inlet the place ahead, is formed a rubbish band.When suction inlet process rubbish band, the rubbish grit is sucked suction pipe, be transported in the dustbin.The rubbish grit will experience dust removal process several times entering suction inlet through in the process of dustbin, and in dustbin, the carrier gas after the dedusting is discharged from air outlet with the detention of rubbish grit.The dust-absorption sweeping type road-sweeper be use in the world the most general, the road-sweeper that kind is maximum.The dust-absorption sweeping type road-sweeper not only has dry type and wet type, and various structural shape has.The vacuum dust-absorption sweeping type is to utilize negative pressure to collect rubbish; Brush use cylindrical brush, dish brush focus on rubbish on the conveyor, deliver in the dustbin then, or directly are thrown in the rubbish hopper.According to the method that rubbish is discharged, road-sweeper also can be divided into turning over before the hopper and turns over formula etc. after turning over formula and lift bucket behind formula, the hopper.This type road-sweeper utilizes four nozzles that are installed in the broom front that the road surface is squirted, four disc type brushes are swept to assigned position with pavement garbage, the high pressure positive blower of dust produces the air-flow of high-speed motion, form stronger negative pressure at the suction nozzle place, rubbish is sucked hopper, because the hopper space is strengthened suddenly, air velocity through the suction nozzle suction pipe reduces suddenly, through once more with spray the bonding dust of moisture, rubbish, the particle that density is bigger sinks down into the hopper bottom in action of gravity, leaf, paper etc. are blocked by gauze wire cloth, through the hopper dividing plate air is further evolved again, after blower fan, exhaust hood is discharged.The brush of present dust-absorption sweeping type road-sweeper and suction nozzle arrangement form mainly contain to crouch in the rearmounted suction nozzle of mid-four brushes, the mid-four brushes+suction nozzle and sweep about rearmounted suction nozzle, mid-both sides upright sweeping+centre and can turn round long crouching and sweep, split both sides and be not with three kinds of forms of the short suction nozzle of blowback.The road-sweeper of preposition two brushes+mid-two brushes, mid-suction nozzle has that cleaning is directly perceived, the cleaning effect better, suck granularity big (100mm), inhale the higher (characteristics such as 3~20km/h) of the speed of sweeping, but thicker because of preposition brush at dust, when pressing dirt undesirable, the dust of being kicked up can directly influence driver's sight line, and front overhang is longer; Upright sweeping+centre can be turned round long crouching and sweeps, splits both sides and can not clean the road both sides with the road-sweeper of the short suction nozzle form of blowback about mid-both sides, but cleaning speed is slow, cleaning width narrow (2.2m), suck that granularity is less, secondary pollution is bigger, and former sand-lime road cleaning effect is not good enough.
Blower fan is not installed on the pure sweeping road-sweeper, and its cleaning work is to sweep by the limit rubbish in roadside is swept under the sweeping machine, by rolling and brushing or rolling and brushing+material casting mechanism rubbish is swept dustbin again.Just developed the drum-type road-sweeper as far back as twentieth century.Afterwards, along with the exploitation and the development of dust-absorption sweeping type road-sweeper, the drum-type road-sweeper was little by little replaced by the dust-absorption sweeping type road-sweeper.The drum-type road-sweeper is just swept (throwing) by the machinery cleaning with rubbish and is gone into dustbin, so need not to carry out wet dust removal or dry dust removal.Sweeping machine dust not when making cleaning work, the front of drum-type sweeping machine generally all is provided with sprinkler head.Drum-type road-sweeper operating principle such as Fig. 1: the drum-type sweeping machine moves ahead, and cylinder clockwise rotates simultaneously, and dustbin is swept and be thrown into to rubbish, because cylinder is circular, so will have certain initial velocity just can make it enter dustbin to rubbish.The advantage of this road-sweeper is: simple in structure, cheap, and can be in the small space operation.Shortcoming is: vibration and noise are bigger, influence environment, and operating personnel's health is had than macrolesion.Simultaneously, reentrainment of dust is serious, needs watering to cooperate.

Annotate: sweeping efficiency and cleaning ability are two distinguishing notions.
Sweeping efficiency (Sweeping Effieieney)
So-called sweeping efficiency is meant the ratio of the pavement garbage amount before pavement garbage amount that the road-sweeper operation removes and the operation, represents with percentage.Formula 1-1 is the design formulas of sweeping efficiency.
μ = W 0 - W 1 W 0 × 100 % - - - 1 - 1
In the formula:
μ---sweeping efficiency, %;
W 0---the pavement garbage amount before the operation, g/m 2
W 1---post-job pavement garbage remaining quantity, g/m 2
Cleaning ability (Sweeping Capacity)
The cleaning ability is meant when road-sweeper carries out operation, under the prerequisite of the sweeping efficiency that reaches regulation, and the maximum operation area of finishing in the unit interval, its value equals the product of maximum cleaning speed and cleaning width.Formula 1-2 is the design formulas of cleaning ability, is used for performance test.Formula 1-3 is the design formulas of cleaning ability in the general sense.
F max = 3600 × L T × B - - - 1 - 2
F=1000V 0×B 1-3
In the formula:
F Max, F---cleaning ability, m 2H -1
L---cleaning distance, m;
B---cleaning width, m;
T---cleaning time, s;
V 0---cleaning speed, kmh -1
Interpretation:
When road-sweeper travels with the speed of 5km/h, the chain wheel speed is selected low grade, the middle-grade and high-grade cleaning work that carries out respectively, the effect after the cleaning by table as can be seen, no matter under the sort of chain wheel speed, its cleaning effect is all relatively good.Hence one can see that, and road-sweeper is running at a low speed under the situation, and low chain wheel speed can well clean the road surface, and excessively improving the chain wheel speed does not have practical significance.Because this moment, the road-sweeper speed of a motor vehicle was lower, the cleaning work efficient of road-sweeper is also lower but simultaneously.
When road-sweeper travels with the speed of 10km/h, the chain wheel speed selects low grade, middle-grade, top grade to carry out cleaning work respectively, the effect table after the cleaning as can be seen, the chain wheel speed is when low grade, the cleaning effect is relatively poor; When middle-grade, the road surface of cleaning is cleaner; When top grade, road cleaning quite clean.
Adopt the compound mode of middle-grade travel speed and middle-grade chain wheel speed to carry out cleaning work, the operating efficiency of road-sweeper is general, and cleaning rate can meet the demands substantially; Adopt the compound mode of middle-grade travel speed and high-grade chain wheel speed to carry out cleaning work, then the operating efficiency of road-sweeper is general but cleaning rate is higher.
When road-sweeper travels with the speed of 15km/h, the chain wheel speed is selected low grade, the middle-grade and high-grade cleaning work that carries out respectively, the effect after the cleaning by table as can be seen, the chain wheel speed is when low grade, road-sweeper has not almost cleaned ability; When middle-grade and when high-grade, the road surface all has the more grains of sand residual.On the road surface after the cleaning, the residual grains of sand begin to present the zonal distribution of inclination, and " traction " phenomenon has promptly taken place as can be seen, and this is because under higher cleaning speed of a motor vehicle state, and the chain wheel speed is low to be caused.Therefore,, need further chain wheel speed if improve the clean level on road surface, cleaning back, though otherwise the operating efficiency of road-sweeper is higher, and the cleaning rate of road-sweeper is relatively poor.
Simultaneously, also to determine different cleaning strategies according to different rubbish character, as the rubbish bigger to particle, should adopt low chain wheel speed to run at a low speed the scheme of speed in joining, can adopt the high speed travel speed to increase work efficiency to lighter rubbish such as leaves.
In sum, the chain drive formula cleaning agency of the utility model road scavenging vehicle has improved refuse sweeping and collection mode, has reduced energy consumption, has reduced noise, has improved the cleaning effect.
