Description

Dust-absorption cleaning vehicle

Technical field

The utility model belongs to environment sanitation facility technical field, is specifically related to a kind of dust-absorption cleaning vehicle.

Background technology

About the technical information of road-sweeper, can in disclosed Chinese patent literature, be seen in, typical in the transmission mechanism of notice of authorization CN2484349Y(refuse cleaning vehicle), the sweeping transmission mechanism of CN200974963Y(road sweeper), the sweeping transmission mechanism of CN101130945A(road-sweeper) and the sweeping transmission mechanism of CN101528837B(road-sweeper), etc.The working forms of these patents and/or patent application scheme is: by a pair of dish type broom (also can claim disk broom) that is positioned at car body front, the rubbish on road is driven to the central region of vehicle, simultaneously swept the garbage collection box on vehicle by being positioned at the rubbish that the middle part of vehicle or the drum broom at rear collect dish type broom.But drum broom easily produces twice pollution that dust flies upward in the process of the rubbish being collected by dish type broom being got rid of to garbage collection box in inertia mode, and drum broom to dust to clear away effect poor, the situation that dust residues in road is comparatively outstanding, thereby aforementioned patent and patent application scheme exist this logical fraud.

Because dust-absorption cleaning vehicle can suck garbage collection box with the form of negative pressure by the pavement garbage being collected by dish type broom, thereby be conducive to avoid secondary pollution, and owing to being able to simplified structure and thering is road pavement dust remove effective strong point without use drum broom.

In disclosed Chinese patent literature, can be seen in equally the technical information about dust-absorption cleaning vehicle, slightly " the round-the-clock vacuum sweeper in full region ", " air blowing dust collecting sweeping car " and a kind of road-sweeper of CN100567647C introduction that CN2876173Y provides recommended as notice of authorization CN2858765Y to exemplify, these patent schemes all can embody aforesaid secondary pollution and the road pavement dust avoided and remove effective strong point.But these patent schemes are owing to ordering about the wheel walking of vehicle and ordering about dust collection mechanism work respectively by independently actuating unit is responsible, thereby logical fraud below existing: one, energy consumption is large, because under road-sweeper is in running order, need make wheel motion by a series of transmission by motor (being generally diesel engine), need drive dust collection mechanism work by power separately simultaneously, thus two covers separately independently power consume the energy simultaneously, cause cleaning cost to increase; Its two, because needs use two independently power, thereby cause the integral vehicle cost of road-sweeper to improve, and overall volume is large and deadweight increases; Its three, owing to there being two power independently, thereby increase inspection difficulty.

If adopt a set of for order about the motor of vehicle to run and shoulder the effect as the power of dust collection mechanism under the prerequisite that does not increase this engine power simultaneously, aforementioned technical problem just can be eliminated so, because the travel speed of road-sweeper under cleaning state is comparatively slow, again because only under cleaning state dust collection mechanism just devote oneself to work, vice versa.So, road-sweeper under cleaning state because low running speed is enough to superfluous power to apply to dust collection mechanism, so without increasing the power of motor.But in disclosed patent and non-patent literature up to now, be showed no all corresponding technology enlightenments, the applicant has done useful design for this reason, has finally formed technical scheme described below.
