AI Technical Summary
Existing road sampling devices have limited mobility, making it difficult to quickly drill multiple holes for sampling; handheld sampling equipment is difficult to apply sufficient drilling pressure stably, resulting in low drilling efficiency and easy breakage or deviation of core samples.
A sampling device was designed, comprising a support plate, a vertical guide rail, a screw, a slider, a drive mechanism, a sampling drill barrel, and a fixing mechanism. The fixing mechanism quickly anchors the sampling drill barrel to the road surface, and the drive mechanism coordinates the vertical feed and rotation of the sampling drill barrel to ensure that the drill barrel enters the ground vertically.
This enabled the sampling device to be quickly and securely anchored on the road surface, improving the installation speed and drilling efficiency of the sampling equipment, preventing device displacement and overturning, and ensuring the verticality and integrity of the drill core.
