[0011] Preferably, the support blocks at the top of the two semi-circular tubes are arranged symmetrically about the hinge.

[0012] Preferably, the protrusion is located at the top of the outer wall of the semi-circular tube, and the through groove is located at the position corresponding to the highest point of the inclined lower end face of the sampling tube.

[0013] Preferably, the outer side of the protrusion does not protrude from the through groove, and a gap is provided between the top of the inner wall of the through groove and the upper surface of the protrusion.

[0014] Preferably, the buckle is a female-female buckle.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention uses two semi-circular tubes, closed at the top and open at the bottom, that are hinged to each other inside a sampling cylinder. When the tube is inserted into the soil for soil sampling, the sample enters both semi-circular tubes. After removing the semi-circular tubes from the sampling cylinder and laying them flat, one semi-circular tube is flipped upwards. The resulting soil sample closely resembles the original stratified state, facilitating stratified soil sampling, reducing errors in test results, and is simple and convenient to use. It solves the problem that existing soil augers are inconvenient for stratified soil sampling. Attached Figure Description
