A core sampling device

Abstract

The invention relates to the technical field of engineering detection sampling, and specifically discloses a core drilling sampling device, comprising: a driving component, a sampling component and a limiting component, the sampling component comprising an outer cylinder and two arc plates, the two arc plates are slidably arranged along the radial direction of the axis of the outer cylinder, the limiting component is arranged on the two arc plates, when coring, the driving shaft rotates the outer cylinder, cuts a sample core in a target area, after cutting to a specified depth, the limiting component cuts off the bottom end of the sample core, and moves the two arc plates toward the axis of the outer cylinder, the two arc plates are closed to form a complete cylinder to clamp the sample core; a core drilling sampling device of the invention is provided with an arc plate and a limiting component, when cutting the sample core, the limiting component is used to cut off the bottom of the sample core, and the bottom of the sample core is supported, and the arc plate clamps the sample core to maintain the integrity of the sample core.
