Description

Technical Field

[0001] The utility model relates to the technical field of highway detection equipment, in particular to a highway compaction experimental detection device. Background Art

[0002] The highway compaction detection device is a device used to detect the compaction of the highway pavement. In order to ensure that the quality of the highway meets the standards after the construction work is completed, the compaction detection device is generally used for detection work.

[0003] Chinese utility model application number CN202320945364.1 discloses a road compaction test detection device, including: a base, a mounting groove is provided on the surface of the base, an inner container is placed inside the mounting groove, support plates are fixedly connected to both sides of the upper surface of the base, a flap is rotatably connected to the top of the support plate, and a hand lever is fixedly connected to one side of the flap. In the utility model, a ring knife, a flap, a support plate, a limit bolt and a spring are provided. When the ring knife completes sampling, the limit bolt is pulled to disengage the limit bolt from the inside of the limit socket, thereby releasing the clamping state between the limit bolt and the flap. The upper handle drives the flap to rotate, completes the deflection movement of the ring knife, and adjusts the bottom direction of the ring knife to facilitate taking out the sample from the ring knife, which greatly facilitates the staff to take out the sample from the ring knife, and solves the problem that the sample from the ring knife is not easy to take out in the existing device. However, the device still has some shortcomings during use: the device drives the telescopic cylinder and the ring knife to rotate by rotating the flap, and the components that need to be rotated in the actual operation process are relatively large, which makes it still troublesome to take out the sample. At the same time, the sample inside the ring knife is easy to spill out during rotation, which makes the quantitative sampling not accurate enough. Utility Model Content
