Abstract
The present invention relates to a street-sweeping lorry, as compared with existent technology it is characterized by that in its suction nozzle device a back-blowing nozzle and roll-sweeping mechanism are added, it utilizes the back-blowing nozzle, roll-sweeping mechanism, suction nozzle device suction port, suction port bend, dust box, fan inlet, fan outlet, air channel, soft tube and back-blowing nozzle to form a closed waste air circulating system. It can prevent the contaminated air sucket in the course of cleaning road surface from discharging into atmosphere to result in secondary pollution, and can suck the garbage with large specific weight and large volume into the dust box so as to greatly improve cleaning effect.
Description
Technical field:
The present invention relates to a kind of sweeping machine.
Background technology:
Existing sweeping machine is being brought into play positive effect aspect the cleaning cities and towns, yet it also comes with some shortcomings.Little as, suction rubbish light specific gravity, volume, the waste gas of discharge has certain pollution to air.
The disclosed road-sweeper of Chinese patent CN87210902U by two sweep dish, dust guiding tube, sweep roller, heavy dirt case constitutes jointly to sweep and inhales mechanism, and is installed on the chassis, and corresponding transmission mechanism is housed again.
The disclosed Wet-dry dust-absorption sweeping type of Chinese patent CN2412031Y sweeping machine, be characterized in that the sweeping machine chassis is provided with wet dust removal device and the front end be made up of water tank and sprinkler system and establishes the conversion air door, in establish the dust arrester of folded formula filter cylinder, pulse of compressed air jetting deashing.This sweeping machine will be done wet two cover dust arresters and be located in the sweeping machine, can use separately, and use can mutually combine again.
The disclosed sweeping machine of the flat 2-85407 of Japan makes dustbin, suction pipe, deduster form negative pressure by blower fan.Sweep the dust that captures and enter dustbin by upright by suction pipe branch both sides, because of flow velocity slows down, major part is deposited in the dustbin, again by deduster dedusting for the first time, tiny dust is with the import of air by blower fan, after export to the laying dust water deduster and carry out final dusting, enter in the air from the bottom, chassis again by two wing passages.
In sum, existing sweeping machine all will be to airborne release waste gas, even the wet dust removal device also unavoidably to the contaminated gas of airborne release, thereby produces secondary pollution.
Summary of the invention:
In view of the present situation of present sweeping machine, the objective of the invention is to design a kind of sweeping and inhale sweeping machine effective, do not produce pollution not to the contaminated gas of airborne release, to environment.
Architectural feature of the present invention is achieved above-mentioned purpose, this sweeping machine comprises assistant engine, hydraulic oil pump, hydraulic oil container, blower fan, solenoid operated directional valve, watering case, uprightly sweeps, nozzle unit and dustbin, it is characterized in that having a blowback mouth in the nozzle unit of this sweeping machine, the terminal pipeline of this blowback mouth is a flexible pipe, suction inlet by nozzle unit, suction inlet bend pipe, dustbin, blower fan import, blower fan outlet, air channel, flexible pipe, blowback mouth, rolling and brushing mechanism form a closed circuit scheme for exhaust gas circulation system to the suction inlet of nozzle unit.
In addition, also be provided with a rolling and brushing mechanism in the nozzle unit, the rotating shaft of rolling and brushing mechanism is fixed on the housing of nozzle unit by connection and lifting regulating mechanism.
This structure overcome prior art with the garbage disposal that sucks after toxic emission in air, cause the drawback of environment pollution in various degree, can guarantee sweeping machine circulation and be not discharged in the air repeatedly in the scheme for exhaust gas circulation system of gas that cleaning will suck during road at sweeping machine, thereby can avoid sweeping machine in cleaning, to cause to second environmental pollution, simultaneously, can also guarantee that rubbish such as the sweeping machine queen closer that volume is bigger, handstone, cullet are swept is drawn onto in the dustbin, makes cleaning reach optimum efficiency.It is a kind of environmental protection equipment such as city, traffic, airport, harbour, square of optimization.
Fig. 1 is the structural representation of this sweeping machine.
The specific embodiment:
As seen from the figure, this sweeping machine by assistant engine 1, hydraulic oil pump 2, hydraulic oil container 3, blower fan 4, solenoid operated directional valve 5, watering case 6, uprightly sweep 7, air channel 8, suction inlet 9, rolling and brushing mechanism 10, blowback mouth 11, dustbin 12 and roller 13 constitute, this nozzle unit is made of suction inlet 9, rolling and brushing mechanism 10 and blowback mouth 11, the suction inlet bend pipe of nozzle unit and dustbin 12 imports are communicated with, and the rotating shaft of rolling and brushing mechanism 10 is fixed on the housing of nozzle unit by connection and elevating mechanism.The housing of nozzle unit is connected on the sweeping machine auxiliary girder.The effect of connection in the rolling and brushing mechanism 10 and adjusting elevating screw is to adjust the distance of rolling and brushing mechanism to ground easily according to the degree of wear of rolling and brushing mechanism, and can guarantee sweeping machine with proportion be less than or equal to 2.8 or rubbish such as the bigger queen closer of volume, handstone, cullet sweep and be drawn onto in the sweeping machine dustbin, the cleaning effect is significantly improved.Roller 13 is used for supporting nozzle unit when cleaning, makes rolling and brushing mechanism kiss the earth stable freely, and rolling and brushing mechanism is clockwise direction rotation rolling and brushing, and roller 13 is then for being rotated counterclockwise.The blowback mouth that this sweeping machine is provided with, by rolling and brushing mechanism, nozzle unit suction inlet, suction inlet bend pipe, dustbin, blower fan import, blower fan outlet, air channel, flexible pipe, blowback mouth, form a closed circuit scheme for exhaust gas circulation system, the gas row who discharges because of the blowback mouth is to ground that the case cover of nozzle unit, and this moment, the negative pressure of suction inlet is also being inhaled the rubbish of sweeping the ground that the nozzle unit cover, the result, the gas of this sweeping machine oneself discharging just enters the nozzle unit suction inlet with rubbish simultaneously under the effect of negative pressure, reach the purpose of waste gas closed cycle.Compared with the prior art, the contaminated air that the present invention the most outstanding advantage has sucked when being to avoid sweeping machine when the cleaning road surface suction to be swept is discharged into the secondary pollution that in the air environment is caused, can will suck dustbin again than the rubbish great, that piece is big, having improved the cleaning effect greatly, is a kind of optimization environmental protection equipment that is worthy to be popularized.
Claims (2)
1, a kind of sweeping machine, comprise assistant engine, hydraulic oil pump, hydraulic oil container, blower fan, solenoid operated directional valve, watering case, uprightly sweep, nozzle unit and dustbin, it is characterized in that having in the nozzle unit blowback mouth, the terminal pipeline of this blowback mouth is a flexible pipe, suction inlet by nozzle unit, suction inlet bend pipe, dustbin, blower fan import, blower fan outlet, air channel, flexible pipe, blowback mouth, rolling and brushing mechanism form a closed circuit scheme for exhaust gas circulation system to the suction inlet of nozzle unit.
