For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0023] As shown in the drawings, the utility model includes a sampling cylinder 1 and a drill rod 2,

[0024] The sampling cylinder 1 is provided with a fixing column 3 at the top, a lateral slot 4 is formed on the outer wall of the sampling cylinder 1, the bottom of the fixing column 3 is located in the lateral slot 4, an arc-shaped cover plate 5 is arranged in the lateral slot 4, the upper part of the arc-shaped cover plate 5 is detachably installed on the fixing column 3 through bolts, and the drill rod 2 is installed at the top of the sampling cylinder 1.

[0025] A group of drill blades 6 are evenly arranged at the bottom of the sampling cylinder 1 in a ring shape.

[0026] An arc-shaped positioning table 7 is arranged at the bottom of the lateral slot 4, and a positioning slot is formed in the bottom of the arc-shaped cover plate 5 and used in cooperation with the arc-shaped positioning table 7. The arc-shaped positioning table 7 supports the arc-shaped cover plate 5 from below and also plays a certain positioning role, so that the arc-shaped cover plate 5 is more stable when being installed.

[0027] A group of air holes 8 are formed in the fixing column 3. When the sampling cylinder 1 is inserted into the soil, the air in the sampling cylinder 1 is discharged, which is convenient for sampling.

[0028] A pair of through holes are formed in the upper part of the arc-shaped cover plate 5, and threaded holes corresponding to the through holes are formed in the fixing column 3, bolts pass through the through holes and are screwed into the threaded holes, so as to press the arc-shaped cover plate 5 against the fixing column 3.

[0029] An inverted circular table-shaped knocking table 9 is arranged at the top of the drill rod 2.

[0030] A pair of sampling handles 10 are arranged at the upper part of the drill rod 2.

[0031] The end of the sampling handle 10 is downwardly inclined. When the sampling handle 10 is held, it is not easy to slide, which is convenient for the staff to exert force.

[0032] A rubber protective sleeve is arranged on the sampling handle 10.

[0033] In example 1, the staff places the soil coring device to the designated sampling position, holds the sampling handle 10 and presses downward, so that the drill blades 6 at the bottom of the sampling cylinder 1 are inserted into the soil.

[0034] If the hardness of the soil is low, the sampling cylinder 1 is continuously pushed downward by rotating the drill rod 2 in cooperation with the cutting action of the drill blades 6, and after reaching the designated sampling depth, the soil coring device is pulled upward by rotating the drill rod 2.

[0035] If the soil is hard, after the sampling cylinder 1 is preliminarily inserted into the soil, the sampling cylinder 1 is hammered into the soil by knocking the inverted circular table-shaped knocking table 9 with a hammer, and after reaching the designated sampling depth, the soil coring device is pulled upward by rotating the drill rod 2.

[0036] After sampling, knock the outer wall of the sampling cylinder 1 to separate the soil from the sampling cylinder 1, and form a columnar soil sample. If the soil is combined with the inner wall of the sampling cylinder 1 very tightly, it cannot be taken out by knocking. In this case, unscrew the bolt by a screwdriver, take off the arc-shaped cover plate 5, leak out part of the soil, insert a shovel into the soil sample, and take out the sample downward. After taking out, cover the arc-shaped cover plate 5 and fix it by the bolt.
