Description

Technical Field

[0002] A paver is a construction equipment mainly used for paving various materials on the base and surface layers of highways. It is composed of various systems that cooperate with each other to complete the paving work. With the rapid development of my country's logistics industry, highways, expressways and expressways are being constructed in large quantities, and the use of pavers has also increased greatly. It can evenly spread asphalt concrete on the roadbed according to the thickness and width required by the project, and give it preliminary compaction and leveling, which can not only maintain the quality of the paved road surface, but also increase the speed of paving the road surface.

[0003] In the actual paving process of asphalt pavement, since the asphalt mixture is prone to solidification in a low temperature environment, it is necessary to heat and stir the asphalt mixture. The insulation equipment of the existing paving machine is usually configured in the form of a heat-conducting storage cylinder to insulate the asphalt mixture. When the asphalt mixture flows out from the discharge port, the temperature will quickly drop and solidify, thereby affecting the construction effect. In addition, during the paving process of the asphalt mixture, a special person is required to use an inserted thermometer to measure the temperature after paving. The operation is cumbersome and the labor cost is high. Therefore, a low-temperature pavement construction paving device is needed, which can automatically monitor the temperature after paving in real time during the paving process, reduce labor costs, and heat and insulate the asphalt mixture at the discharge port to avoid adhesion and solidification of the mixture due to rapid temperature drop during paving, ensure that the pavement after paving is flat and smooth, and improve the construction effect.
