The soil sample collector according to claim 1, wherein the cover plate is further provided with a first limiting hole, the first sampling barrel is provided with a second limiting hole, the second limiting hole is communicated with the first limiting hole, the second sampling barrel is provided with a third limiting hole, and the soil sample collector further comprises a limiting piece; under the condition that the second sampling tube is buckled with the first sampling tube, the limiting piece can be simultaneously inserted into the first limiting hole, the second limiting hole and the third limiting hole so as to lock the position of the second sampling tube.

5. The soil sample collector of claim 4, wherein the limiting member comprises a limiting rod and a pull ring which are connected with each other; under the condition that the second sampling tube is buckled with the first sampling tube, the limiting rod can be simultaneously inserted into the first limiting hole, the second limiting hole and the third limiting hole so as to lock the position of the second sampling tube.

6. A soil sample collector according to any one of claims 1 to 5 wherein the first sampling barrel and the second sampling barrel are both semi-cylindrical barrels.

7. The soil sample collector of claim 6, wherein the outer peripheral surface of one end of the first sampling cylinder, which is far away from the cover plate, is provided with a guide protrusion, and the guide protrusion extends along the circumferential direction of the first sampling cylinder.

8. The soil sample collector of claim 7, wherein the first sampling barrel has a straight edge that mates with the second sampling barrel, the first end of the guide protrusion is adjacent to the straight edge, the second end of the guide protrusion extends away from the straight edge, and the width of the guide protrusion gradually increases from the first end of the guide protrusion to the second end of the guide protrusion.

9. The soil sample collector according to claim 7, wherein a flow guide groove is further formed in the outer peripheral surface of one end, away from the cover plate, of the first sampling cylinder, the flow guide groove is located on one side, facing the cover plate, of the guide protrusion, and the flow guide groove extends along the circumferential direction of the first sampling cylinder.

10. The soil sample collector of claim 9, wherein the first sampling barrel has a straight edge that mates with the second sampling barrel, the first end of the flow guide slot is adjacent to the straight edge, the second end of the flow guide slot extends away from the straight edge, the width of the flow guide slot increases gradually from the first end of the flow guide slot to the second end of the flow guide slot, and the depth of the flow guide slot decreases gradually from the first end of the flow guide slot to the second end of the flow guide slot.
