Description

Technical Field

[0001] The utility model relates to the technical field of road pollution cleaning and removing vehicles, in particular to a negative pressure resistant differential separation mechanism used for road pollution cleaning and removing vehicles. Background Art

[0002] Road pollution cleaning and removal vehicles have been widely used in the field of cleaning and sanitation. Road sweepers are a kind of efficient sanitation equipment that integrates road cleaning and maintenance. Road pollution cleaning and removal vehicles can be used for dust removal and road maintenance on streets, communities, airports, parks, urban main roads, highways and other roads.

[0003] However, traditional road pollution cleaning and removal vehicles have the following disadvantages:

[0004] The cleaning mechanism on traditional road pollution cleaning and removal vehicles drives the circular push plate to rotate through the oil cylinder, so that the liquid and solid mixture can be effectively separated in a shorter time. The design of the push plate can quickly push the solid matter to the bottom of the tank, while the liquid is quickly discharged through filtration or gaps. Due to the complex internal structure of the cleaning mechanism, cleaning and maintenance may become difficult. Long-term operation may cause solid matter to accumulate in the slide rails, oil cylinder mounting seats and other parts, affecting the normal operation of the equipment and reducing the separation efficiency of impurities and moisture. Utility Model Content
