Description

Billboard wiping equipment for municipal roads

technical field

The invention relates to billboard wiping equipment, in particular to billboard wiping equipment for municipal roads.

Background technique

The literal meaning of highway is public road, public transportation road, many vehicles such as automobiles, bicycles, rickshaws, horse-drawn carriages and pedestrians can walk, of course, different roads have different restrictions. It is also called Malu among the people, such as the usage in "Malu Angel", which is not limited to the exclusive use of horses. There is a difference between general roads and automobile-only roads. The latter has more and more road grades, so there are two specifications for secondary roads. There were no restrictions on early roads, most of which were simple roads. Later, different roads had different restrictions; due to the increasingly developed traffic, there are more and more roads with restricted use, especially some roads are specially used for cars, and the type of expressway has been developed. , It is specially designed for the whole closed use of the car.

The billboard is a signal tool for starting the next production process in the pulling system, or moving the work-in-progress to the downstream process. The term means "signal" or "signal board" in Japanese. Generally refers to all outdoor media that convey advertising information. The billboards in the existing roads are difficult to be cleaned, so road billboard wiping equipment is needed.
