Description

Technical Field

[0001] The utility model relates to the technical field of geological and mineral exploration, in particular to a mineral geological exploration sampling device. Background Art

[0002] Mineral geological sampling refers to the process of collecting soil, rock, and mineral samples and conducting analysis and testing during geological exploration and mineral development. By analyzing this geological information, it can provide a reference basis and feasibility assessment for the mining and utilization of mineral resources, thereby improving the comprehensive development and utilization efficiency of mineral resources. An existing mineral geological exploration sampling device (Announcement No.: CN221594337U) has at least the following defects in use:

[0003] In the above scheme, the deep soil is pulled out as a sample by inserting the collection tube into the soil and pulling it out in the form of a straight tube, which is convenient for staff to explore the mineral geological conditions. However, in actual use, because the soil has a certain fluidity and it is difficult to fill the soil sample during sampling, when the sample is pulled out of the soil, the soil on the upper layer of the sampling tube falls to the bottom under the action of inertia, affecting the accuracy of the bottom sample, and only using the bottom end of the device to collect samples, it is impossible to judge the overall condition of the stratum. Therefore, a mineral geological exploration sampling device is developed. Utility Model Content
