Description

Technical Field

[0001] This utility model relates to the technical field of asphalt testing, and in particular to a device for detecting the temperature of asphalt mixture in the auxiliary hopper of a mobile conveyor. Background Technology

[0002] Currently, during asphalt pavement construction, to improve the uniformity of asphalt mixtures, mobile conveyors are often used to pre-mix the arriving asphalt mixture before conveying it to the paver. Due to the certain unloading height, auxiliary hoppers need to be equipped on the paver to reduce temperature loss from the asphalt mixture. Asphalt is a temperature-sensitive material, its performance is closely related to temperature.

[0003] Currently, construction site managers often use digital thermometers to detect the temperature of asphalt mixture in the auxiliary hopper. This requires a 3-5 minute wait, necessitating workers to climb onto the continuously operating paver's auxiliary hopper, resulting in significant physical exertion. Furthermore, the elevation difference makes reading the temperature difficult, posing a substantial safety hazard. Therefore, there is an urgent need for a device that is simple in structure and operation, provides reliable results, offers high efficiency, and ensures safety for detecting the temperature of asphalt mixture in the auxiliary hopper of a mobile conveyor.
