Description

Technical Field

[0001] The utility model relates to the technical field of core hyperspectral mineralization and alteration detection, in particular to a core grinding and scanning device. Background Art

[0002] Cores are cylindrical rock samples taken from underground through drilling during mineral exploration and development. They are the most intuitive and practical data for understanding underground strata and mineral-bearing characteristics, and can help researchers understand the age, lithology, and sedimentary characteristics of strata, as well as the physical and chemical properties of reservoirs and the oil, gas, and water content.

[0003] At present, hyperspectral imaging technology is usually used to obtain spectral data of cores, and the mineralization and alteration information of cores is extracted through the spectral data. Finally, a three-dimensional drilling data model is established based on this data. This can effectively help researchers more accurately understand the formation mechanism, spatial distribution and resource potential of ore deposits, and improve the exploration efficiency and mining benefits of mineral resources.

[0004] Before obtaining the spectral data of the core, the surface to be scanned needs to be polished to reduce the roughness of the surface to be scanned. However, in terms of time and space, the polishing process and the scanning process are currently carried out independently of each other, and the process is not seamlessly connected, resulting in low detection efficiency.

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Reference Figure 1, a core grinding and scanning device provided by the utility model, includes a conveying mechanism 100, a grinding assembly 200, and a scanning assembly 300. When in use, the conveying mechanism 100 transports the core sample 400 at its left end to its right end. The grinding assembly 200 is arranged on the left side of the conveying mechanism 100. When in use, the core sample 400 is fixed at the left end of the conveying mechanism 100. Then the grinding assembly 200 grinds the core sample 400 fixed on the conveying mechanism 100 in the X, Y, and Z axis translational freedom degrees, so that the surface roughness of the core sample 400 to be measured meets the measurement requirements. After the grinding is completed, the conveying mechanism 100 transports the core sample 400 thereon to its right end. The scanning assembly 300 is arranged on the right side of the conveyor 100. Specifically, the scanning assembly 300 includes a hyperspectral imaging device 310, a lighting device 320, and a distance measuring device 330. When in use, the hyperspectral imaging device 310 scans the core sample 400 in the X, Y, and Z axis translation degrees of freedom and multiple rotational degrees of freedom to perform an all-round scan of the polished core sample 400, thereby obtaining complete spectral information of the core sample 400. The lighting device 320 illuminates the core sample 400 in one translational degree of freedom and one rotational degree of freedom. Optionally, the lighting device 320 illuminates the core sample 400 in the Z axis translational degree of freedom and the rotational degree of freedom around the X axis, or illuminates the core sample 400 in the Z axis translational degree of freedom and the rotational degree of freedom around the Y axis. The distance measuring device 330 measures the height of the core sample 400 in the rotational degree of freedom around the Z axis, so that when the hyperspectral imaging device 310 is scanning, the distance measuring device 330 is rotated in the XY plane to move it out of the imaging field of the spectral imaging device 310, thereby avoiding the distance measuring device 330 blocking the imaging field of the hyperspectral imaging device 310. In addition, the hyperspectral imaging device 310 can adjust the imaging focal length and the imaging field of view according to the measurement data of the ranging device 330 , and the lighting device 320 can adjust the illumination position according to the measurement data of the ranging device 330 .

The first screw drive mechanism 213 is disposed between the first base 211 and the first slide 212.

The second screw drive mechanism 222 is arranged between the second slide 221 and the first slide 212.

The grinding wheel mechanism 240 is fixedly disposed on the third slide 231. In this way, through the cooperation of the X-axis translation mechanism 210, the Y-axis translation mechanism 220 and the Z-axis translation mechanism 230, the grinding wheel mechanism 240 can be translated in three translation degrees of freedom of the X, Y and Z axes according to the height of the core sample 400 and the position on the conveying mechanism 100, thereby adjusting the grinding position of the grinding wheel mechanism 240.

In addition, in order to reduce the influence of high temperature generated by the contact between the high-speed rotating grinding wheel 242 and the core sample 400, a water spray port 23111 is provided on the protective cover 2311. During grinding, the water spray port 23111 is connected to an external water supply device, so that the cooling water transported by the water supply device is sprayed out through the water spray port 23111 and sprinkled on the grinding area.

[0036] In some optional embodiments, such as Figure 1 As shown, the conveying mechanism 100 includes a belt conveyor 110 and a tray 120.

Specifically, the fourth slide 312 is slidably disposed on the frame 311, the fourth screw drive mechanism 313 is disposed between the fourth slide 312 and the frame 311, and when the screw in the fourth screw drive mechanism 313 rotates forward and backward, the fourth slide 312 moves along the Z-axis direction on the frame 311. The linear motion mechanism 314 is slidably disposed on the fourth slide 312, the fifth screw drive mechanism 315 is disposed between the fourth slide 312 and the linear motion mechanism 314, and when the screw in the fifth screw drive mechanism 315 rotates forward and backward, the linear motion mechanism 314 moves along the X-axis direction or along the Y-axis direction on the fourth slide 312. The angle adjustment mechanism 316 with multiple rotational degrees of freedom is arranged at the output end of the linear motion mechanism 314, and the hyperspectral imaging probe 317 is arranged on the angle adjustment mechanism 316. When the linear motion mechanism 314 is working, it drives the angle adjustment mechanism 315 to move as a whole, and if the linear motion mechanism 314 is on the fourth slide 312 along the X-axis direction, the linear motion mechanism 314 drives the angle adjustment mechanism 315 to move as a whole along the Y-axis direction, and if the linear motion mechanism 314 is on the fourth slide 312 along the Y-axis direction, the linear motion mechanism 314 drives the angle adjustment mechanism 315 to move as a whole along the X-axis direction, so that the hyperspectral imaging probe 317 can perform an all-round scan of the core sample 400 below it. In this embodiment, optionally, the linear motion mechanism 314 can use a linear motor module.

[0038] In some optional embodiments, such as Figure 5 , Figure 6 As shown, the angle adjustment mechanism 316 includes a bracket 3161, a first semicircular ring 3162, a first rotating driving member 3163, a second semicircular ring 3164, a second rotating driving member 3165, a limiting ball 3166, a first sliding member 3167, and a second sliding member 3168. The bracket 3161 is arranged on the linear motion mechanism 314, and the translation of the output end of the linear motion mechanism 314 drives the bracket 3161 to translate. Both ends of the first semicircular ring 3162 are rotatably arranged on the bracket 3161, and the first rotating driving member 3163 is fixedly arranged on the bracket 3161 and is transmission-connected to one end of the first semicircular ring 3162.
