Description

road cleaning vehicle

technical field

The invention relates to the field of road cleaning equipment, in particular to a road cleaning vehicle.

Background technique

The road cleaning vehicle is a new type of efficient cleaning equipment that integrates road cleaning, garbage recycling and transportation. To put it simply, it is to modify the road cleaning function on the chassis of a special car. In addition to the chassis engine, the vehicle is equipped with an auxiliary engine. The four brushes are driven by hydraulic motors, with fans, dustbins, water tanks, etc. Grouped equipment. This brand-new model can clean the ground, curb edge, curb, and sprinkle water on the ground after cleaning at one time. It is suitable for cleaning operations in various climates and different dry road surfaces.

Generally, it is classified by the way of walking, operation or dust removal, usually by operation method: 1, hand-push cleaning vehicle and walk-behind cleaning vehicle, 2, self-propelled cleaning vehicle, 3, pure sweeping cleaning vehicle 4 , Suction sweeping cleaning vehicle, 5, Pure suction cleaning vehicle (multifunctional full suction road sweeping vehicle), 6, Dry cleaning vehicle (vacuum cleaning vehicle), 7, Wet cleaning vehicle, 8, Full suction cleaning vehicle .

At present, most of the domestic road cleaning vehicles are multi-functional full-suction road sweepers, which are new products developed with patented technology. The air movement way collects and stores dust and garbage, so it is very efficient. This product can effectively reduce dust pollution, improve air quality, reduce the content of inhalable particulate matter in the air, and improve people's living environment. Its features: 1. Full suction dry cleaning. All operations are completed with airflow, combined with blowing and suction, without secondary dust. 2. No need for brushes or water, saving energy, dry suction, once the car passes, the ground is clean. 3. Good cleaning effect. Dust ranging from tens of microns to general small stones, leaves and other sundries can be effectively removed, with a cleaning efficiency of over 98%. 4. Simple structure, few wearing parts, convenient use and maintenance, and simple operation. 5. Low maintenance cost.

However, due to the imperfect development of the dust filtration system of domestic road cleaning vehicles, the dry suction cleaning process often leads to the secondary emission of dust, resulting in dust pollution in the air. In response to this problem, most domestic cleaning vehicle manufacturers adopt wet cleaning methods in order to reduce the quality requirements of dust filters. However, the wet cleaning method makes the dust sticky after being wet, which makes the filter screen clogged and affects the working efficiency of the exhaust fan. In addition, due to the integrated installation of the exhaust fan and the garbage bin in domestic cleaning vehicles, when there is more and more garbage in the garbage bin, it will cause great interference to the exhaust fan's exhaust efficiency, making the exhaust fan's exhaust efficiency It is greatly reduced, and even the exhaust air volume of the exhaust fan cannot make the dust suction port suck the garbage.
