Description

Technical Field

[0001] This invention relates to the technical field of geological sampling, and in particular to a geological surveying instrument for mineral engineering. Background Technology

[0002] In the fields of mining engineering, civil engineering, and geological research, geological surveying is a fundamental task for resource assessment, environmental evaluation, and engineering construction. Its core lies in obtaining representative underground soil and rock debris samples and conducting precise analysis of samples at different depths. Therefore, the sampling capacity, efficiency, and sample quality of surveying equipment directly affect the accuracy of subsequent data analysis and the reliability of engineering decisions.

[0003] Currently, the surveying equipment commonly used in the industry has relatively limited functionality and obvious limitations. On the one hand, deep sampling usually uses auger drilling equipment, which can drill to a certain depth, but the samples obtained are easily mixed during the lifting process, and lack the ability to collect samples in real time during sampling, resulting in cross-contamination of samples from different strata, which seriously affects the analysis results.

[0004] On the other hand, the collection of loose surface media requires a separate set of surface sampling equipment. This means that in a complete survey operation, staff often need to carry multiple sets of equipment to alternately conduct surface and subsurface sampling. This is not only cumbersome and time-consuming, significantly reducing survey efficiency, but also makes it difficult to ensure that the sampling locations are completely consistent due to equipment relocation and multiple positioning, thus disrupting the continuity and comparability of stratigraphic data. Summary of the Invention

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figures 1-3 This invention discloses a geological surveying instrument for mineral engineering, which includes a base 1. The base 1 provides overall support and fixation, and its bottom can be equipped with adjustable feet or anti-slip pads to adjust the height and level according to different terrains, so as to ensure the overall stability of the equipment during the sampling process.

[0021] A sampling tube 2 is fixedly installed on the base 1. The sampling tube 2 penetrates the base 1 vertically, and its bottom end is machined with a hook 21. The hook 21 can be embedded in the ground during operation, effectively preventing the equipment from slipping and ensuring stable sampling operation.

[0022] The sampling cylinder 2 houses a spiral sampling section 3, which includes a rotating rod 31, a spiral sampling blade 32, and a first driving member 33. The spiral sampling blade 32 is fixedly surrounded around the rotating rod 31. The first driving member 33 is coaxially connected to one end of the rotating rod 31, providing it with rotational power, thereby driving the sampling blade 32 to rotate, realizing the drilling and upward transport of soil or rock debris.

[0023] A collection cylinder 4 is connected to one side of the sampling cylinder 2 to receive and temporarily store samples transported by the spiral sampling unit 3. The collection cylinder 4 has multiple sampling drawers 41 arranged in layers from top to bottom. Each sampling drawer 41 is connected to the cylinder wall of the collection cylinder 4 via a sliding rail for easy removal of samples after sampling. The bottom of each sampling drawer 41 is equipped with a filter structure, except for the bottom of the bottom sampling drawer, which is a solid plate structure suitable for collecting ultrafine particles or liquid media. The mesh size of each filter layer decreases progressively from top to bottom, thereby achieving gradient sieving and classified collection of samples.

[0024] It should be understood that a detection unit can be integrated inside the collection tube 4 to conduct real-time geological detection and survey while sampling.

[0025] The geological surveying instrument disclosed in this invention also includes a reciprocating motion component 5 for controlling the vertical feeding and retraction of the spiral sampling section 3. The reciprocating motion component 5 includes at least one guide rod 51 fixedly mounted on the base 1, and a sliding member 52 fitted onto the guide rod 51. The sliding member 52 is connected to the first driving member 33 and can reciprocate along the guide rod. An elliptical guide ring 53 is further fixedly mounted on the guide rod 51, with guide teeth 54 machined on both opposite inner sides of the guide ring. A corresponding sliding tooth 55 is provided on the outer periphery of the sliding member 52, which can mesh with the guide tooth 54 on one side of the guide ring 53, thereby generating a meshing thrust when the sliding member 52 rotates, converting its rotational motion into vertical linear motion.

[0026] A transmission rod 56 is coaxially connected to the sliding member 52, and the transmission rod is connected to the first driving member 33 through a bearing. A driving bevel gear 57 is coaxially fixed on the rotating rod 31, and a driven bevel gear 58 is coaxially fixed on the transmission rod 56. The driving bevel gear 57 and the driven bevel gear 58 mesh with each other to realize power transmission and direction conversion, and finally drive the rotating rod 31 to rotate.

[0027] The geological surveyor disclosed in this invention also includes a surface sampling unit 6 for collecting samples of loose soil or sediment from the surface. The surface sampling unit 6 mainly includes a second driving component 61, which is fixed to the base 1 by a bracket. The output end of the second driving component 61 is connected to a first rotating rod 62, and a first rotating wheel 63 is coaxially fixed on the first rotating rod. A second rotating rod 64 is rotatably mounted above the second driving component via a bearing support, and a second rotating wheel 65 is coaxially fixed on the second rotating rod. A chain 66 is wound between the first and second rotating wheels, and multiple sampling hoppers 67 are installed on the chain at certain intervals. When the second driving component 61 is activated, the driving chain 66 rotates cyclically, and the sampling hoppers 67, driven by the chain, sample at a low point and flip at a high point, pouring the collected surface sample into the collection cylinder 4.

[0028] To accommodate different sampling depth requirements, a support base 68 is fixed on the base 1, and a detachable lifting block 69 is provided between the support base and the base of the second drive component 61. By adding or removing the lifting block, the installation height of the second drive component 61 can be adjusted, thereby changing the working height of the chain 66 and the hopper 67. The support base 68 and the lifting block 69 can be made of mutually attractive magnetic materials to facilitate quick assembly, disassembly, and positioning.

[0029] In this embodiment of the invention, the first driving component 33 and the second driving component 61 can be selected as servo motors, stepper motors, or hydraulic motors; the guide rod 51 can be arranged in a symmetrical double-rod layout to enhance stability; the sampling drawer 41 can be provided with a handle or a label area for operation identification; and each moving part can be equipped with a protective cover or lubrication interface as needed. The implementation principle of this invention: This geological surveyor performs sampling through two parts. When sampling at deeper locations is required, the first drive unit 33 is activated, driving the reciprocating motion component 5 and the spiral sampling unit 3. The spiral sampling unit 3 rotates and, driven by the reciprocating motion component 5, drills downward to the target depth. After sampling, it is lifted by the reciprocating motion component 5, conveying the deep sample upward to the collection cylinder 4. In other words, driven by the reciprocating motion component 5, the spiral sampling unit 3 simultaneously converts rotational motion into precise vertical feeding and retraction, automatically completing the drilling, lifting, and conveying of deeper soil or rock cores. When sampling and testing of the surface layer is required, the surface sampling unit 6 drives the hopper 67 to rotate cyclically via a chain 66, automatically flipping at high points to collect and deliver loose surface samples. Both collected samples are ultimately conveyed to the collection cylinder 4, which has a multi-stage stratified filtration function, for automatic sieving and classification. The sampling drawer 41 inside the collection tube 4, with its mesh size decreasing layer by layer from top to bottom, can perform graded filtering and storage of samples, ultimately obtaining multi-layered and clearly classified soil or rock debris samples in one go.

Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
