technical field

The invention relates to the technical field of road sweepers, in particular to an all-weather road sweeper.

Background technique

Mechanized cleaning of outdoor roads is an important symbol of sanitation modernization, and road sweepers are widely used in cleaning operations in non-motorized lanes, sidewalks, squares, parks and other places due to their small size and flexible steering. A large amount of dust will be generated during the cleaning operation of the road sweeper, which will cause secondary pollution to the environment. For this situation, there are currently two solutions: wet dust suppression and dry dust removal. The dry dust removal of common road sweepers on the market is mainly filtered through dust removal devices such as filter cartridges and cloth bags. However, the dust removal device undertakes most of the dust removal work during the working process. Congealed into blocks, it is more difficult to clean up, which greatly affects the garbage pickup and dust removal effect of the whole machine.
