Description

Technical Field

[0001] The utility model relates to the technical field of roadbed sampling equipment, in particular to a sampling mechanism for detecting the compaction degree of a highway base. Background Art

[0002] The roadbed is the foundation of the track or road surface. The compaction degree of the roadbed will largely determine the service life of the highway. Therefore, during the highway construction process, construction personnel need to sample the roadbed and test the compaction degree. Publication number: CN211773520U discloses a utility model patent for a highway base compaction detection sampling device for highway construction. In the patent, a motor drives the gear to rotate, and the gear drives the sleeve to rotate through a gear ring, thereby causing the threaded screw to rotate. Since the screw is threadedly connected to the support plate, the screw moves up and down relative to the support plate 1 when it rotates, thereby driving the sampling barrel to rotate and move toward the roadbed to complete the sampling. However, the sampling barrel is only supported by the screw when it moves up and down or when sampling, and no other supporting structure is set, resulting in low stability of the sampling barrel when in use, which will affect the sampling effect of the device. For this reason, we provide a sampling mechanism for highway base compaction detection. Utility Model Content
