[0002] In the process of tobacco leaf planting in China, there are many factors affecting the final quality of tobacco leaves. Among the numerous influencing factors, the soil for tobacco leaf planting and the external climate conditions for tobacco leaf planting are very crucial. Therefore, it is particularly important to detect the soil before planting. During the detection process, soil sampling is required first. Most of the existing sampling devices drill into the soil through screws for sampling. For example, the utility model with the publication number CN219798761U records an agricultural soil sampling device, which relates to the technical field of soil investigation and sampling, including a metal frame and a drill. Compared with the existing ordinary agricultural soil sampling device, a drill is provided on one side of the metal frame, and a roller assembly is provided below the other side of the metal frame. An expansion rod assembly is provided above the metal frame. This device drills the screw into the soil through the drill for sampling, but the integrity of the soil sample cannot be guaranteed during the sampling process of this device, so the hierarchical structure of the soil and the soil compaction condition cannot be detected. For this reason, the utility model provides a soil sampling device for tobacco planting, so as to ensure the integrity of the soil during the sampling process. Summary of the Utility Model
