[0003] The existing geological sample collection device can only obtain the soil at a certain depth and is not convenient for obtaining soil samples at different depths at the same location. When relevant personnel need to sample the soil at different depths at the same location, they need to sample the same location multiple times, which greatly reduces the sampling efficiency. At the same time, sampling the same location multiple times may cause the soil at different depths to fall to different depths, affecting the sampling results. To solve the above problems, a geological sample collection device is proposed. Content of the Utility Model
