AI Technical Summary
Technical Problem
Existing core sampling methods are time-consuming and labor-intensive, easily leading to core sample breakage, and cannot sample at depths less than the surface layer thickness.
Method used
A surface sampling device for road material analysis is used. By forming an annular depression on the outer wall of the core sample through protrusions, and combining the reciprocating rotation of the core cylinder with the lateral movement of the translation frame, the core sample can be controlled to fracture and be removed.
Benefits of technology
It enables rapid and non-destructive core sample extraction, avoiding the impact damage of traditional prying methods, and can accurately extract core samples at a predetermined depth, improving detection efficiency and core sample integrity.

Abstract
本申请提供了一种路面材料分析用面层取样装置，包括基座、芯筒和加压组件；基座上具有与其沿水平方向滑动连接的平动架，平动架上具有与其沿竖直方向滑动连接的升降架；芯筒转动连接在升降架上，且芯筒内壁上具有多个凹槽，每个凹槽中均滑动嵌接有一凸块；加压组件与多个凹槽连通，用于向凹槽内加压，以驱动每个凸块均向芯筒中心轴移动至抵接芯样外壁，从而向芯样持续提供朝向中心的作用力；在此基础上，通过驱动芯筒按顺时针方向和逆时针方向往复旋转，即可在芯样表面形成环形凹陷；随后，驱动平动架往复移动，可令芯样自环形凹陷处断开。本申请提供的路面材料分析用面层取样装置，实现快速取样，且取样深度可灵活调节，以适应用户的不同需求。
