The soil sampling probe is a tool used for soil sampling. Soil testing and sampling is a key step in soil quality assessment and agricultural management. Its purpose is to obtain representative soil samples for detailed soil analysis and testing. The sampling process requires the probe to be inserted vertically into the soil and ensure that the probe reaches the required depth. After extracting the soil sample, the probe is removed to obtain the soil sample inside the probe.

A sampling hole 13 is provided at the lower end of the outer shell 1, and a sampling probe 2 is provided inside the sampling hole 13. The sampling probe 2 is cylindrical, and the lower end of the sampling probe 2 is sharp after processing, which is convenient for drilling and sampling in a hard environment. The surface of the sampling probe 2 is slidably connected to the sampling hole 13, and the top of the sampling probe 2 is fixedly connected to a sliding plate 3. The four ends of the sliding plate 3 are fixedly connected to sliding blocks 31, and the sliding block 31 is slidably connected to the slide groove provided on the inner wall of the outer shell 1. A threaded screw 4 is provided on one side of the sampling probe 2, and the surface of the threaded screw 4 is threadedly connected to the sliding plate 3.
