Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixture stirring equipment, in particular to a flow-adjustable asphalt self-flowing spraying device. Background Art

[0002] There are two ways to feed asphalt in traditional asphalt mixing equipment: pumping and gravity flow. When pumping, the pressure is high, which can achieve the effect of asphalt spraying, but the cost is relatively high. When gravity flow is used, asphalt is fed by its own gravity and material fluidity. The feeding points are concentrated and a spraying curtain cannot be formed. It is easy to cause caking after contact with powder, resulting in long mixing time and uneven mixing.
