The fixed shaft rotates with the rotation of the rotating rod, thereby driving multiple blades to rotate together to generate wind, and the powder that falls under the walkway is sucked into the collection box to recover the powder. At the same time, the rotation of the fixed shaft will cause the scraper to rotate together to scrape the connecting net to prevent the powder from blocking the connecting net.

[0015] S4. Finally, use a fluorescent lamp to illuminate the walkway. Through the bright light on the walkway, the defects on the surface of the walkway can be detected.

[0016] The advantages of the present invention are that the walkway is vibrated up and down during its rotation. Since the defect-free part has a weak attraction to the powder, the vibration will cause the powder to fall, thereby improving the accuracy of the detection and being beneficial to the detection. At the same time, the fallen powder can be recovered and reused. BRIEF DESCRIPTION OF THE DRAWINGS
