A base course sampling device for road construction

Abstract

This invention discloses a base sampling device for road construction, including a movable base, casters, a lifting mechanism, a sampling mechanism, a sampling hole, a through hole, a turntable, a motor, a placement groove, and an installation groove. This invention features a reasonable and simple structure, low production cost, and convenient installation. Starting the motor rotates the entire turntable, allowing the empty placement groove to be positioned directly below the sampling cylinder, facilitating sample collection and placement. The extension of the cylinder causes the movable hole seat to move downwards, which in turn drives the connecting shaft downwards via a connecting block. This downward movement of the connecting shaft then pushes the sample into the placement groove via a push-out block, improving sample retrieval convenience. Starting the motor rotates the turntable, allowing the through hole to be positioned directly below the sampling mechanism, facilitating sampling at the next location.
