[0024] A sampling assembly 3 is provided at one end of the material guide assembly 2 away from the detection tank 1. The sampling assembly 3 includes a rotating tube 31, a sampling tube 32 and a sampling tooth 33. The rotating tube 31 is rotatably connected to the end of the material guide assembly 2, the sampling tube 32 is threadedly connected to the bottom end of the rotating tube 31, and a plurality of sampling teeth 33 are annularly fixedly connected to the bottom end of the sampling tube 32.

[0025] A crushing assembly 4 is arranged inside the sampling tube 32, and the crushing assembly 4 includes a mounting ring 41 and crushing teeth 42. The crushing teeth 42 are fixedly connected inside the sampling tube 32, and a plurality of crushing teeth 42 are fixedly connected in a ring shape to the inner side of the mounting ring 41.

[0026] In the utility model, during detection, the sampling of the asphalt pavement is carried out by controlling the sampling component 3, and the sampling tube 32 is driven to rotate by the rotating tube 31. The sampling teeth 33 can quickly sample the sample during the rotation process. However, the sampled asphalt is mostly columnar. During the rotation of the sampling tube 32, the crushing component 4 will be driven to rotate, and a plurality of rotating crushing teeth 42 will crush the upwardly moving asphalt column. The utility model ensures that the asphalt sample is in a crushed state during sampling, which can improve the efficiency of sampling detection.
