Description

Technical Field

[0001] The present application relates to the technical field of geological exploration equipment, and in particular to a geological exploration sampling device. Background Art

[0002] Geological exploration is an important part of modern resource development and environmental protection, among which sampling technology is particularly critical. Traditional geological exploration sampling methods mainly rely on manual excavation or the use of simple tools for sampling. Although these methods are simple and easy to use, they have many limitations in collecting samples in complex terrain and deep buried layers. With the advancement of science and technology, automated sampling equipment has gradually become mainstream. They not only improve the efficiency and accuracy of sampling, but also can adapt to a wider range of environmental conditions. Such equipment usually includes various drilling machines, samplers, etc., and is widely used in the fields of petroleum, minerals, soil pollution monitoring, etc.

[0003] In the existing geological exploration sampling technology, common solutions mainly include manual samplers, electric samplers and hydraulically driven sampling systems. Manual samplers rely on manual operation and are suitable for shallow sample collection, but they are labor-intensive and have low precision. Electric samplers use motors to drive the drill rod to rotate to achieve the collection of deeper samples, with high work efficiency and certain accuracy. The hydraulically driven sampling system uses high-pressure liquid to drive the piston to complete the sampling action of the drill bit, which is suitable for greater depths and harder formations. In addition, there are some composite sampling devices that integrate multiple power sources and technical characteristics, such as pneumatic-electric hybrid drive systems, which further enhance the flexibility and scope of application of sampling.

[0004] However, the sampling devices in the prior art generally have some shortcomings, especially in that they are easily disturbed by external factors during the sample collection process, resulting in sample mixing or loss. After the samples are taken out, additional operations are often required to preserve them, which increases the complexity and time cost of field work. Therefore, how to design a geological exploration sampling device that can quickly extract and preserve samples has become a technical problem that needs to be solved urgently.

Under the action of the first limit spring 85, the first positioning rod 83 is ensured to be firmly stuck in the positioning groove 811, thereby maintaining the open state of the cover plate 81.

[0049] Before connecting and sleeved the sampling box 4 on the drill rod 3, first pull the first positioning rod 83 in the direction away from the movable groove 61 to make the first positioning rod 83 withdraw from the movable groove 61. At this time, the first limit spring 85 is in a compressed state, and then move the operating block 82 to drive the cover plate 81 to move to a position where the positioning groove 811 is aligned with the first positioning rod 83.

[0051] The cover 81 of the sampling box 4 can be firmly maintained in a closed state to prevent leakage or contamination of the sample during movement. The design of the second positioning rod 86 and the second limit spring 88 ensures that the cover 81 can be reliably locked in a closed state to prevent the cover 81 from accidentally opening due to external vibration or other factors. In addition, when the second positioning rod 86 is clamped in the positioning groove 811, the first positioning rod 83 is also abutted against the side wall of the cover 81, further enhancing the stability of the cover 81 and also enhancing the stability between the first box body 5 and the second box body 6.

[0052] The locking cam 71 is then released, and the locking cam 71 is in a state of being moved horizontally, and the locking cam 71 is moved horizontally to the locking cam 72, so that the locking cam 71 is in a state of being moved horizontally, and the locking cam 71 is moved horizontally to the locking cam 72, so that the locking cam 71 is moved horizontally to the locking cam 72 ... 83 is pulled in the direction away from the cover 81, driving the first positioning rod 83 to withdraw from the positioning groove 811, and the moving operation block 82 drives the cover 81 to move in the direction close to the matching groove 53, and at the same time pulls the second positioning rod 86 to move in the direction away from the matching groove 53, so that the second positioning rod 86 withdraws from the matching groove 53, and the second limiting spring 88 is in a compressed state until the positioning groove 811 is aligned with the second positioning rod 86, and at the same time, the second positioning rod 86 and the first positioning rod 83 are released, so that the second positioning rod 86 is clamped in the positioning groove 811 under the tension of the second limiting spring 88, and the first positioning rod 83 moves in the direction close to the moving groove 61 under the action of the first limiting spring 85 and abuts against the cover 81, completing the closing of the top cover 81; then turn over the sampling box 4, repeat the above steps, and close the cover 81 on the other side of the sampling box 4.
