Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil sampling equipment, and in particular to a soil sampling device. Background Technology
[0002] Soil sampling is a crucial foundational step in soil research, environmental monitoring, and agricultural planting. Accurately obtaining representative soil samples is essential for analyzing soil properties, assessing soil pollution levels, and guiding agricultural production. Traditional soil sampling devices mostly rely on manual operation, using simple tools such as the Luoyang shovel. Sampling with these tools requires repeated manual insertion and extraction of soil, which is not only labor-intensive but also slow. Furthermore, after use, the inner wall of the sampling tube often accumulates a large amount of soil residue. If not cleaned promptly, this residue will contaminate the newly collected sample in subsequent samplings, affecting subsequent analytical results. Utility Model Content
