AI Technical Summary
Traditional road thickness testing devices have difficulty sampling when dealing with road surface materials with high hardness, and impurities are prone to adhering to the outer wall of the sampling tube during the sampling process, affecting the accuracy of the test results and increasing the complexity of cleaning.
The device employs a rotating impact head design, combined with laser scale lines and a cleaning component. The drive and rotation components cause the detection cylinder to press down vertically and rotate, penetrating the road surface. At the same time, a cleaning system and a rotating cleaning brush remove impurities, ensuring the surface of the detection cylinder remains clean.
It improves the efficiency and accuracy of the sampling process, reduces reliance on manual operation, ensures data reliability and ease of cleaning, and avoids impurities affecting data reading.
