The classification receiving component includes a receiving platform 2 and an internal receiving plate 17.

[0020] Specifically, the receiving platform 2 can be detached from the base 1, and through the cooperation of the built-in receiving plate 17 and the receiving platform 2, it can adapt to altered rocks of different sizes, greatly improving the applicability of the device to test samples of different sizes and meeting diverse testing needs. The pressure testing plate 7 is detachably connected to the hydraulic rod 5 through the connecting component, which facilitates quick replacement when the pressure testing plate 7 is worn or needs to be replaced with different specifications, reducing the maintenance cost of the device and ensuring the accuracy and continuity of the testing work.

[0021] Example 2 The second embodiment of this utility model provides a technical solution: the connecting component includes a plug block 9, and a receiving seat 8 is plugged into the bottom end of the plug block 9. The receiving seat 8 is fixedly connected to the center of the upper surface of the pressure detection plate 7.

[0022] Both the receiving seat 8 and the plug block 9 have receiving holes 10 on their sides, and fastening bolts 11 are movably inserted through the inner wall of the receiving hole 10.

[0023] Specifically, after the pressure is applied, the built-in support plate 17 can automatically move upward and become flush with the top of the base 1 under the action of the return spring 16, making it easier to clean up the debris generated after the test, reducing the difficulty and time cost of manual cleaning, and improving the efficiency of the test work.

[0024] Example 3 The second embodiment of this utility model provides a technical solution: a receiving slot 12 is provided on the upper surface of the base 1, and a limiting plug 13 fixedly connected to the bottom surface of the receiving platform 2 is movably inserted into the inner wall of the receiving slot 12.

[0025] A docking groove 14 is provided at the center of the upper surface of the base 1. The built-in support plate 17 is movably inserted into the inner wall of the docking groove 14. The inner wall of the docking groove 14 is fixedly connected to the inner ring 15. The bottom end of the built-in support plate 17 is fixedly connected to the return spring 16. The bottom surface of the built-in support plate 17 abuts against the top of the inner ring 15.

[0026] The bottom end of the return spring 16 is fixedly connected to the inner wall of the receiving inner ring 15.

[0027] Example 4 The third embodiment of this utility model provides a technical solution: In practical applications, the base 1, guide slide rod 3, fixed top frame 4 and other load-bearing structural components can be made of high-strength steel to ensure the stability and strength of the device; the hydraulic rod 5 can be made of high-quality alloy material to ensure the stability and reliability of its pressure output; the receiving platform 2, built-in receiving plate 17 and other components that are in direct contact with the altered rock can be made of wear-resistant and corrosion-resistant engineering plastics or special alloy materials to prevent wear and corrosion.

[0028] The pressure testing plate 7 is designed with a regular shape that matches the shape of common altered rock samples, such as circular or square. Its size can be customized to meet various testing needs; for example, a small testing plate is suitable for small rock samples, while a large testing plate can be used for larger samples. The edges of the pressure testing plate 7 are rounded to prevent unnecessary damage to the rock sample edges during pressure application, which could affect the accuracy of the test results. Furthermore, the lower surface of the pressure testing plate 7 is designed as a smooth, flat plane to ensure uniform contact with the altered rock sample surface during pressure application, resulting in even pressure distribution.

[0029] Multiple pressure sensors are evenly distributed on the lower surface of the pressure testing plate 7 to monitor the pressure values ​​at various points on the rock sample surface in real time during the pressure application process. These pressure sensors are piezoresistive or piezoelectric sensors, capable of accurately measuring minute pressure changes and converting pressure signals into electrical signals for output. By analyzing the pressure values ​​at each point, the stress distribution of the rock sample during the pressure process can be assessed, providing data support for studying the strength characteristics of altered rocks.

[0030] Working principle: When the altered rock strength characteristic testing device is in operation, the altered rock to be tested is placed on the receiving platform 2. The hydraulic rod 5 is activated, which drives the pressure testing plate 7 downward through the connecting components (plug block 9, receiving seat 8, fastening bolt 11) to apply pressure to the altered rock for strength testing. During the pressure application process, if the altered rock is small, the built-in receiving plate 17 will be pressed down, compressing the return spring 16, thereby achieving stable support for small-sized altered rock. After the pressure application is completed, the built-in receiving plate 17 moves upward under the action of the return spring 16 until it is flush with the top of the base 1, making it easy to clean up the debris generated after the test. In addition, since the pressure testing plate 7 is detachably connected to the hydraulic rod 5 through the connecting components, when the pressure testing plate 7 is worn or needs to be replaced with a different specification, the plug block 9 can be pulled out from the receiving seat 8 by loosening the fastening bolt 11, realizing the quick replacement of the pressure testing plate 7. Meanwhile, the receiving platform 2 is movably connected to the receiving slot 12 on the base 1 via the limiting plug 13, and can be disassembled from the base 1 according to actual needs, so as to carry out more flexible receiving operations for altered rocks of different sizes.

[0031] In summary, the receiving platform 2 can be detached from the base 1, and through the cooperation of the built-in receiving plate 17 and the receiving platform 2, it can adapt to altered rocks of different sizes, greatly improving the applicability of the device to test samples of different sizes and meeting diverse testing needs.

[0032] After the pressure is applied, the built-in support plate 17 can automatically move upward and become flush with the top of the base 1 under the action of the return spring 16, making it easier to clean up the debris generated after the test, reducing the difficulty and time cost of manual cleaning, and improving the efficiency of the test work.

[0033] The pressure testing plate 7 is detachably connected to the hydraulic rod 5 via a connecting assembly, which facilitates quick replacement when the pressure testing plate 7 is worn or needs to be replaced with a different specification, reducing the maintenance cost of the device and ensuring the accuracy and continuity of the testing work.
