Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the embodiment provides the following technical solutions:

the soft soil sampler comprises a sampling cylinder 1, a handle connecting part 2 and a sliding hoop 3, wherein the sampling cylinder 1 consists of at least two cylinder wall sheets with the same size and shape; the handle connecting part 2 comprises a handle 21 and a connecting plate 22 fixedly connected with the handle 21, the connecting plate 22 is fixedly connected with connecting rings 23 with the number equal to that of the cylindrical wall sheets, and each cylindrical wall sheet is rotatably connected with the connecting plate 22 through the connecting rings 23; the sliding hoop 3 is connected with the outer wall of the sampling tube 1 in a sliding way.

Each cylinder wall sheet rotates to surround to form a sampling cylinder 1 together, the sliding hoop 3 is arranged on the outer wall of the sampling cylinder 1, and the assisting cylinder wall sheets surround.

The first embodiment:

referring to fig. 1-4, the sampling tube 1 is composed of two equal-sized and same-shaped tube wall sheets, each tube wall sheet has a semicircular section and forms a cylindrical structure after being abutted, and the two tube wall sheets, i.e., the first tube wall sheet 11 and the second tube wall sheet 12, are correspondingly fixedly connected with two connecting rings 23 at the matching positions of the connecting plates 22.

Second embodiment:

not shown in the figure, the sampling tube 1 is composed of three equal-sized and same-shaped tube wall sheets, each tube wall sheet is in a one-third arc shape in cross section and forms a cylindrical structure after being encircled and butted, and correspondingly, three connecting rings 23 are fixedly connected to the matching positions of the connecting plates 22.

The third embodiment:

not shown in the figure, the sampling tube 1 is composed of four equal-sized and same-shaped tube wall sheets, each tube wall sheet has a quarter-arc cross section and forms a cylindrical structure after being encircled and butted, and correspondingly, four connecting rings 23 are fixedly connected to the matching positions of the connecting plates 22.

Each of the above embodiments includes:

referring to fig. 1-2 and 4, the lower end of each wall sheet is provided with a knife edge 13, the outer wall of the wall sheet is provided with a limit protrusion 14 near the knife edge 13, the upper end of the wall sheet is provided with a suspension rod 15, and the suspension rod 15 is concentrically matched with a connecting ring 23.

Each of the above embodiments includes:

referring to fig. 5 and 6, the cross section of the inner wall of the sliding collar 3 is a structure with a small top and a big bottom, and the maximum inner diameter of the sliding collar is smaller than the outer diameter of the whole circle of the limiting protrusion of the enclosed sampling tube 1.

The cross section of the inner wall provided with the limiting protruding part 14 and the sliding hoop is of a structure with a small top and a big bottom, and the maximum inner diameter of the cross section of the inner wall of the sliding hoop 3 is smaller than the outer diameter of the whole circle of the limiting protruding part of the enclosed sampling tube 1, so as to limit the sliding of the sliding hoop 3 in the range above the limiting protruding part 14 on the outer wall of the sampling tube 1.
