Description

Technical Field

[0001] The utility model relates to the field of synchronous pavers, in particular to an anti-emulsified asphalt clogging device for synchronous pavers. Background Art

[0002] Emulsified asphalt is a liquid asphalt formed by combining asphalt and an emulsifier under certain conditions, creating either an oil-in-water or oil-in-water mixture (depending on the type of emulsifier). Emulsified asphalt is typically high-temperature road asphalt that has been mechanically agitated and chemically stabilized (emulsified) before being dispersed into water, resulting in a liquefied form that has very low viscosity and excellent fluidity at room temperature. It can be used at room temperature and can also be used with cold, damp stone.

[0003] Emulsified asphalt is typically applied to the road surface using a spraying device. Synchronous spreading pavers are equipped with built-in asphalt tanks. However, due to capacity limitations, the amount of emulsified asphalt loaded is often insufficient to complete a road section. This necessitates stopping the machine for refilling during construction, which can't guarantee sustained results. Furthermore, traditional spraying devices can't continuously stir the emulsified asphalt while spraying. Consequently, when spraying is paused, the emulsified asphalt slowly solidifies, eventually clogging the spray pipe and causing problems. Therefore, we need to propose an anti-emulsified asphalt clogging device for synchronous pavers. Utility Model Content
