Description
Technical Field
[0001] This utility model relates to the field of gold mine sampling technology, and in particular to a multiple sampling device for gold mine geological exploration. Background Technology
[0002] Gold geological exploration refers to a comprehensive geological work aimed at finding, delineating, and assessing gold resources. It utilizes various methods and technologies, including geology, geophysics, geochemistry, and remote sensing, to systematically investigate and analyze stratigraphy, lithology, structure, alteration zones, and mineralization characteristics. Its main tasks include identifying prospective gold-producing areas, extracting anomaly information, determining the location and extension direction of ore bodies, analyzing ore grades, and estimating resource reserves. Gold geological exploration is the prerequisite and foundation for mineral development, spanning stages such as prospecting prediction, preliminary exploration, detailed exploration, and feasibility studies. It provides a scientific basis for gold mine development, ensuring the economic viability and feasibility of subsequent mining operations.
[0003] In gold mine geological exploration, sampling is a core step in obtaining ore body characteristics and assessing resource reserves. Currently, most existing gold mine geological exploration sampling devices adopt an exposed spiral conveyor shaft design, lacking an adjustable protective sleeve. This not only makes the conveyor shaft susceptible to damage from environmental factors such as mud, sand, and rock debris, but also increases the safety hazards of equipment wear and operator accidental contact. Although the exposed structure facilitates cleaning and maintenance, problems such as mud blockage, mechanical collisions, and accidental scratches still occur under complex geological conditions and field operation environments, seriously restricting the continuity and accuracy of sampling.
[0004] Therefore, there is an urgent need for a multi-sampling device that can achieve multi-level, segmented, and continuous sampling, and can also cover and adjust the spiral conveyor shaft with an adjustable protective sleeve, in order to improve exploration efficiency, ensure personnel safety, and guarantee sample representativeness. Based on this, we propose a multi-sampling device for gold mine geological exploration. Utility Model Content

[0014] In summary, this utility model has at least one of the following beneficial effects:
[0015] 1. The multi-sampling device designed in this scheme can precisely control the exposed length of the screw conveyor shaft through the flexible cooperation of the adjusting sleeve and the sampling cylinder frame, realizing flexible adjustment according to the sampling needs at different depths. The adjusting sleeve includes components such as a ground support plate, a grip steering wheel, and a first connecting plate. The operator can adjust the height of the adjusting sleeve in real time by gripping the steering wheel. At the same time, the adjusting screw hole on the first connecting plate, in cooperation with the second motor and the adjusting screw, can realize the extension and retraction adjustment of the adjusting sleeve. When the second motor is powered on, the adjusting screw rotates clockwise or counterclockwise. With the help of the threaded engagement and the guide structure, the position of the adjusting sleeve at one end of the sampling cylinder frame can be easily adjusted. Retracting the adjusting sleeve exposes one end of the screw conveyor shaft to adapt to different sampling depths, while extending the adjusting sleeve can store the screw conveyor shaft to prevent it from being exposed and causing accidental injury, thereby improving the safety of equipment use and providing reliable protection for gold mine sampling under complex geological conditions.
[0016] 2. The multi-sampling device designed in this scheme, through the innovative structure of the guide base plate and the annular guide groove, can stabilize the running trajectory of the screw conveyor shaft, achieving high stability of the equipment in high-speed sampling operations. When the multi-sampling device is sampling, the first motor, which is powered on, can drive the screw conveyor shaft to rotate at high speed. The guide base plate at one end of the screw conveyor shaft matches the annular guide groove structure on one side of the limiting connection cover and adopts a sliding fit. This structural design not only enhances the rigid connection between the screw conveyor shaft and the sampling cylinder frame, but also effectively prevents the screw conveyor shaft from swaying or shaking during drilling and sampling. During multi-level sampling, the guide base plate and the annular guide groove continue to play a role in ensuring the stable operation of the screw conveyor shaft, thereby improving the stability of the equipment in the field of gold mine sampling technology and ensuring the accuracy and reliability of sampling data.

The telescopic adjusting groove 14 matches the structure of the sampling tube frame 1, and the first guide blocks 15 match the first guide groove. The first guide block 15 and the first guide groove 10 are in a sliding fit. Through the structural design of the sliding fit between the first guide block 15 and the first guide groove 10, the adjustment sleeve 2 of the sampling tube frame 1 can play a guiding and limiting role around its extension and retraction adjustment. One end of the spiral conveying shaft 7 is equipped with a guide base plate 18. An annular guide groove 19 is opened around one side of the limiting connection cover 3. The annular guide groove 19 and the guide base plate 18 are structurally matched. The annular guide groove 19 and the guide base plate 18 are in a sliding fit.

The sampling tube frame 1 can also be disassembled, connected, repaired and replaced according to the usage.
[0030] Working Principle: The multi-sampling device designed in this scheme mainly consists of a sampling cylinder frame 1, an adjusting sleeve 2, a limiting connecting cover 3, an adjusting bracket 4, and a sample storage 5. The adjusting sleeve 2 integrates a ground support plate 11, a gripping steering wheel 13, a first connecting plate 16, a telescopic adjusting groove 14, and a first guide block 15 in a circular array. The first connecting plate 16 achieves threaded engagement with the second motor 21 and its output adjusting screw 22 through the adjusting screw hole 17. The first guide block 15 slides with the first guide groove 10 on the side wall of the sampling cylinder frame 1. When the second motor 21 is powered on, it can drive the adjusting screw 22 to rotate clockwise or counterclockwise, which can flexibly adjust the extension and retraction of the adjusting sleeve 2. When the adjusting sleeve 2 is retracted to one end of the sampling cylinder frame 1, the spiral conveying shaft 7 can be exposed at one end of the sampling cylinder frame 1 to adapt to different sampling depths. When the adjusting sleeve 2 is extended to the predetermined position, it can completely cover and hide the exposed spiral conveying shaft 7.
[0031] In this multi-sampling device, when the first motor 6 is powered on and drives the spiral conveyor shaft 7 to rotate at high speed inside the sampling cylinder frame 1, the guide base plate 18 installed at one end of the spiral conveyor shaft 7 matches the annular guide groove 19 opened on the side of the limiting connection cover 3, and the two are in sliding fit. Since the annular guide groove 19 and the guide base plate 18 have the same structural height, they can provide reliable radial constraint and trajectory guidance during the operation of the spiral conveyor shaft 7, while enhancing the rigid connection between the spiral conveyor shaft 7 and the sampling cylinder frame 1, preventing shaft sway or vibration caused by complex geological conditions or changes in drilling torque.
