Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

As shown in fig. 1 and 4, the sedimentary column layering improvement device according to the embodiment of the present invention comprises a mud collecting pipe 1, wherein the mud collecting pipe 1 is a hollow pipe, a sleeve 2 is connected to the top end of the mud collecting pipe 1 through a thread, the sleeve 2 comprises a plurality of sub-sleeves, and two adjacent sub-sleeves are connected in a sliding manner; a plurality of clamping grooves 4 are uniformly formed in the side wall of the mud collecting pipe 1, and inserting pieces 5 are clamped in the clamping grooves 4; adjacent sub-sleeves can slide telescopically so that the length of the sleeve 2 can be adjusted.

As shown in fig. 1, in the present embodiment, the mud collecting pipe 1 and the casing 2 are connected by screws; can prevent to become flexible when extracting mud pipe 1, avoid sampling pipe 1 to drop.

As shown in fig. 1, in the present embodiment, the geometric dimension of the card slot 4 is matched with the geometric dimension of the insertion sheet 5.

As shown in fig. 2-4, in this embodiment, the mud collecting pipe 1, the casing 2, and the inserting piece 5 are all made of stainless steel; has the advantages of firmness, no rustiness, easy washing, easy drying, no mildew and rot and difficult deformation.
