Description

Technical Field

[0001] The invention relates to the technical field of resource exploration equipment, and more specifically to a loose sandstone rotary sampling tube. Background Art

[0002] Resource exploration refers to the exploration, evaluation and management of solid, liquid and gas mineral resources in the fields of development (mining) and management. It is usually led by the government, groups and institutions. It is the process or behavior of investigating all or major resources in a predetermined space and their development, utilization and protection status, or the quantity, quality, distribution and development, utilization and protection status of a selected resource. For the convenience of operation, coring drills are usually used to drill and take samples into the ground, thereby facilitating the exploration of geological resources inside the ground.

[0003] After a single sampling, the loose sandstone often collapses, which requires drilling again for the second sampling. This ultimately leads to low drilling efficiency, long drilling time, and high energy consumption. When conducting drilling and exploration operations in the field, it is also troublesome to carry more fuel or batteries for drilling operations.

[0004] After searching, a Chinese patent with announcement number CN117606846A discloses a resource exploration sampling barrel. By setting a barrel body, a partition plate and a plurality of arc plates are set in the shell body, and the partition plate is used to divide the inside of the shell into a plurality of areas, and the plurality of arc plates seal the feed port during the drilling process. After the sampling barrel reaches a predetermined depth, a control rod is used to drive the pressure rod to move downward, so that the pressure block presses the partition plate to move downward in the shell body. At this time, the rotating rod drives the arc plate to rotate with the cooperation of the rotating groove and the protrusion, so that the feed port is opened. In this case, when the barrel body rotates, the arc plate can be used to guide some loose sandstone samples into the shell body, and finally the sampling operation is completed.

[0005] When the above-mentioned resource exploration sampling tubes are actually used, some existing sampling tubes usually need to drill holes first and then replace the samplers for sampling during the sampling process, which requires multiple adjustments of equipment and tools, increases the difficulty and time cost of operation, and reduces the sampling efficiency, affecting the overall exploration progress.
