A rapid stratified sampling device for rock and soil used in mineral exploration

Abstract

This invention discloses a rapid stratified sampling device for rock and soilin mineral exploration, pertaining to the field of mineral exploration technology. It comprises a drill rod, a sampling structure, a drill bit structure, and a spiral winding structure. The sampling structure consists of two semi-cylindrical bodies, with the top end threadedly connected to the threaded hole at the bottom end of the drill rod. The drill bit structure is rotatably connected to the bottom end of the sampling structure via an annular groove. The outer side of its sleeve is threadedly connected to an inner hexagonal screw rod, and the end of the screw rod is connected to a rotating wheel via a bearing. The rotating wheel can be inserted into the retaining ring of the sampling structure.
