Multi-functional road sweeper

Abstract

The invention discloses a multi-functional road sweeper, which is characterized in that a rolling-brush support frame which can flexibly slide upwards and downwards is arranged in front of a bucket-tipping waste bin; the inside of the rolling-brush support frame is provided with a plurality of gradually-accelerated fan-blade type counter-rotating sweeping rolling-brushes which are horizontally arranged upwards; a garbage guide cover which is provided with arc upper and lower ends and tangent to all the counter-rotating sweeping rolling-brushes is fixedly arranged in front of the rolling-brush support frame; and the fan-blade type counter-rotating sweeping rolling-brushes are driven to simultaneously carry out counter-rotating operation by the powers output by an internal-combustion engine or a direct-current motor, thereby achieving the purpose of sweeping the garbage on road surfaces; and a dust collecting cover is arranged at a dust-raising part above a sweeping scrap chopper, and connected with a dust guide pipe so as to lead dust in a dust-filtrating water storage tank, thereby achieving the purpose of dust purification. According to the invention, through setting up a dust-filtrating water storage tank at a proper position at the top of a cab, and leading dust in the places under or above the water surface of the dust-filtrating water storage tank by the dust guide pipe, and under the actions of a powerful suction fan, water and dust-filtrating rolling brushes, the purposes of purifying the dust in bucket-tipping waste bins and producing the negative pressure are achieved.

Description

technical field [0001] The invention relates to a road sweeper, in particular to a multifunctional road sweeper with energy saving and environmental protection. (Original application number: 200810174393.2) Background technique [0002] At present, there are about three representative types of domestic street sweepers. The first one is a vacuum-type street sweeper that imitates foreign technology. Its disadvantages are: there is a lot of dust in the cleaning garbage, and if the dust is sprayed with water, it will block the dust filter device and waste energy. Huge, in addition, the dry sound and exhaust gas emission are also large during work, which is not conducive to environmental protection; the second is the airflow to complete the work type sweeper, its disadvantage is: although it does not need to use brushes when working, there is no dust flying, but The same waste of energy is huge; the third kind is: planing ground transfer type environmental protection street swe...

Problems solved by technology

[0002] At present, there are about three representative types of domestic street sweepers. The first one is a vacuum-type street sweeper that imitates foreign technology. Its disadvantages are: cleaning garbage There is a lot of dust, and if the dust is sprayed with water, the dust filter device will be blocked, which will waste a lot of energy. In addition, the dry sound and exhaust gas emission will be large during work, which is not conducive to environmental protection; : Although it does not need to use brushes during its work, there is no dust flying, but it also wastes a lot of energy; the third is: planing ground transfer type environmental protection street sweeper (patent number: zL200720147546.5), although it is simple in structure and energy-saving, but, Since there is no dust suppression device and suction fan installed in the dustbin, (that is, the air pressure in the dustbin is greater than the air pressure outside), it is difficult for dust to enter the dustbin, so it is unfavorable for the environment to raise dust during work.
