[0002] Asphalt mixture gradation refers to the process of mixing aggregates of different particle sizes in a certain proportion to meet specific engineering requirements. In asphalt mixtures, aggregates include coarse aggregates (such as gravel and crushed stone) and fine aggregates (such as sand and mineral powder). Grading refers to the classification and combination of these aggregates according to certain specifications and proportions.

[0003] A rapid detection method for aggregate gradation of asphalt concrete pavement in the prior art (publication number: CN102012356B) proposes a complete set of rapid determination methods for asphalt pavement gradation, including image acquisition of asphalt mixture cross section, aggregate information extraction and aggregate gradation conversion, based on the successful experience of using image processing technology in the field of asphalt mixtures. However, this method requires the sampling samples to be polished and cleaned separately before they can be photographed and analyzed, and the detection efficiency is low. Therefore, it is urgent to design an asphalt mixture gradation rapid detection device with more complete functions and higher detection efficiency. Utility Model Content

[0024] When in use, after pushing the equipment to the sampling area, start the electric telescopic rod 16 to drive the grinding disc 6 to gradually descend through the transmission mechanism, and at the same time start the servo motor 14 to drive the grinding disc 6 to grind the asphalt pavement through the connecting rod 7, and then raise the grinding disc 6 through the transmission mechanism, and drive the bracket 3 to slide toward the ground through the adjustment rod 13 in the transmission mechanism, so that the rubber scraper 5 and the cleaning block 4 are against the ground, and push the flatbed cart 1 to quickly clean the grinding area, and then move the flatbed cart 1 so that the camera of the digital camera 17 is aimed at the cleaned sampling area, and at the same time the servo motor 14 is started, and drives the active gear 8 to rotate through the connecting rod 7, and the active gear 8 further drives the driven gear 9 to rotate until the shooting window 10 is aligned with the slot hole for shooting opened on the flatbed cart 1, and then the digital camera 17 takes pictures and samples, and the whole sampling process is fast and simple, avoiding the need to carry various tools for complicated pre-processing, thereby improving the efficiency of the equipment in asphalt mixture gradation detection.

[0025] In this embodiment, the bracket 3 is in a "C" - shaped structure with an upward opening. A connecting shaft 11 is fixedly installed between the open ends of the bracket 3. The connecting shaft 11 is slidably installed in an oblong slot hole opened at the other end of the adjusting rod 13. Square slot holes adapted to the two vertical rods of the bracket 3 are opened at the bottom of the flatbed cart 1. The driving gear 8 and the driven gear 9 are meshed. A photographing window 10 penetrating through its surface is opened at the bottom of the driven gear 9.

[0026] During use, the bracket 3 slides up and down along the square slot holes opened on the flatbed cart 1. Whenever the grinding disc 6 finishes grinding and moves upward, the bracket 3 will slide down, driving the cleaning block 4 and the rubber strip 5 to abut against the ground after grinding. Pushing the equipment can clean the grinding area, facilitating subsequent photographing and sampling, and the sampling effect is better. The driven gear 9 is set to block the photographing end of the digital camera 17 during grinding, playing a protective role for the digital camera 17.

At the same time, the servo motor 14 is started to drive the grinding disc 6 to grind the asphalt pavement through the connecting rod 7 until the grinding depth reaches the required value. Then, the grinding disc 6 is raised through the transmission mechanism, and at the same time, the adjusting rod 13 in the transmission mechanism drives the bracket 3 to slide towards the ground, so that the rubber scraping strip 5 and the cleaning block 4 abut against the ground. Pushing the flatbed cart 1 can quickly clean the grinding area. Move the flatbed cart 1 so that the camera of the digital camera 17 is aligned with the sampled area after cleaning. At the same time, the servo motor 14 is started, driving the driving gear 8 to rotate through the connecting rod 7, and the driving gear 8 further drives the driven gear 9 to rotate until the photographing window 10 is aligned with the slot hole for photographing opened on the flatbed cart 1.
