[0002] During the construction of municipal engineering projects, it is necessary to test the completed municipal road surface to ensure its pass rate. During the testing process, engineering sampling devices are usually required to take samples from the completed municipal road surface. However, existing engineering sampling devices still have shortcomings, such as:

[0003] Sampling devices in general engineering projects involve taking samples from the constructed road surface using a drill rod. However, during the drilling process, dust is generated between the drill bit and the road surface, which can easily affect the construction results. In addition, the process of removing road surface samples from inside the drill rod is relatively complicated and can easily affect the progress of testing and sampling. Therefore, we propose an engineering sampling device to solve the problems mentioned above. Utility Model Content

Both the upper and lower ends of the first rod ring 901 and the second rod ring 902 are threaded. A lower fixing ring 906 is threaded to the lower part of the first rod ring 901 and the second rod ring 902, and the lower part of the lower fixing ring 906 is tapered. The upper part of the first rod ring 901 and the second rod ring 902 is threaded... There is an upper fixing ring 907, and the surface of the upper fixing ring 907 is evenly provided with locking holes 908 to facilitate the locking and fixing of the first rod ring 901 and the second rod ring 902. The upper part of the first rod ring 901 and the second rod ring 902 are locked to the connector 7 through the upper fixing ring 907, and the surface of the connector 7 is locked to the locking holes 908 on the surface of the upper fixing ring 907 through fixing bolts 8, which facilitates the installation of the first rod ring 901 and the second rod ring 902 with the connector 7.

[0021] Please see Figure 1 and Figure 3 A water collection ring 10 is provided below the connecting frame 5, and a water spray nozzle 11 is provided below the water collection ring 10. A water supply tank 12 is installed on the upper left side of the movable base 1, and a water pump 13 is installed on the lower right side of the water supply tank 12.

During sampling, the drive motor 6 inside the hydraulic rod 4 and connecting frame 5 can be turned on to move the sampling rod 9 below the connector 7 downward, allowing the sampling rod 9 to drill into the road surface for sampling. During the sampling process, the water pump 13 below the water supply tank 12 can be turned on to allow the water pipe 14 to drain the water inside the water supply tank 12 into the water collection ring 10. Water is then sprayed onto the top of the sampling rod 9 through the "L"-shaped spray nozzle 11 below the water collection ring 10, allowing the water to slide down the rod wall of the sampling rod 9 and drip onto the dust generated during the sampling process, reducing dust and improving the quality of the construction environment.

[0023] After sampling, the sampling rod 9 can be easily removed from the connector 7 by rotating the fixing bolt 8 on the surface of the connector 7. Then, by rotating the upper fixing ring 907 and the lower fixing ring 906 at the upper and lower ends of the first rod ring 901 and the second rod ring 902, the first rod ring 901 and the second rod ring 902 can be separated to remove the road surface sample inside the first rod ring 901 and the second rod ring 902. The operation is simple, and this is the working principle of the sampling device for this project.
