Traditional magnetic susceptibility measuring tools have significant drawbacks: the sample is easily loosened, and shaking in the field environment affects the measurement accuracy; the magnetization adjustment method is limited and difficult to adapt to different rock and mineral characteristics, making it difficult to accurately control the magnetization intensity; the overall structure is complex to operate, has poor portability, and is not convenient for rapid field operations. Therefore, a magnetic susceptibility tool for field calibration of rock and mineral magnetism is needed to solve the above problems. Utility Model Content

[0024] The magnetization adjustment assembly includes a bracket 6, a sliding seat 7, an electromagnetic coil 8, a vertical rod 9, and a first drive mechanism. The vertical rod 9 is vertically fixed to the upper surface of the edge of the base 1. The sliding seat 7 is sleeved on the outside of the vertical rod 9. The top of the vertical rod 9 is connected to the bracket 6. The electromagnetic coil 8 is slidably connected to the outside of the horizontal rod 10. The horizontal rod 10 is connected to the sliding seat 7. The first drive mechanism is used to drive the sliding seat 7 to move up and down along the vertical rod 9.

[0025] The first drive mechanism includes a handwheel 11, a gear 12, and a rack 13. The rack 13 is fixed on the upper surface of the base 1 along the length of the vertical rod 9 of the support 6. The gear 12 meshes with the rack 13. The rack 13 is a metal spur rack, and the gear 12 is a metal spur gear. The gear 12 is mounted on the sliding seat 7 through a rotating shaft 14. The handwheel 11 is fixedly connected to the end of the rotating shaft 14. The handwheel 11 is internally threaded with a locking bolt 25. Rotating the handwheel 11 can drive the sliding seat 7 to rise and fall to adjust the distance between the electromagnetic coil 8 and the sample.

[0026] It also includes a second drive mechanism, which includes a motor 15, a lead screw 16, and a threaded block 17. The motor 15 is a micro stepper motor, and the motor 15 is connected to one end of the lead screw 16. The lead screw 16 is a metal trapezoidal lead screw. The motor 15 is fixed on the back of the sliding seat 7. The lead screw 16 is laterally rotatably connected inside the sliding seat 7. The threaded block 17 is threadedly connected to the outside of the lead screw 16 and is fixedly connected inside the electromagnetic coil 8. The motor 15 drives the lead screw 16 to rotate, which can drive the electromagnetic coil 8 to move horizontally along the crossbar 10. The electromagnetic coil 8 is a copper coil.

[0027] The measurement and display assembly includes a magnetic susceptibility sensor 18, a data processor 19, and a display screen 20. The magnetic susceptibility sensor 18 is embedded inside the arc-shaped clamp 3 and is a patch sensor. The data processor 19 is installed inside the base 1 and uses a conventional single-chip microcomputer processing module. The display screen 20 is fixed on the top of the bracket 6 and is a small LCD display screen. The magnetic susceptibility sensor 18, the data processor 19, and the display screen 20 are connected sequentially by wires, which are shielded wires, to connect the components.

[0028] The arc-shaped clamp 3 is a metal arc-shaped structure, with a rubber pad 21 with anti-slip texture pasted on the inner side. The surface of the rubber pad 21 is provided with anti-slip texture, and the end of the adjusting screw 4 is provided with a knob 22.

[0029] The base 1 has lockable casters 23 at the bottom, and the bracket 6 has a storage box 24 on one side, which contains spare wires and calibration blocks.

[0030] The working principle of this utility model:

[0031] When using it, first place the rock and mineral sample on the fixed platform 2, turn the knob 22 at the end of the adjusting screw 4, the adjusting screw 4 pushes the arc-shaped clamp 3 closer, and use the rubber pad 21 or silicone pad to clamp the sample. The anti-slip structure prevents the sample from sliding or being damaged.

[0032] Next, based on the characteristics of the rock and mineral, the distance between the electromagnetic coil 8 and the sample is adjusted:

[0033] Vertical distance adjustment: Rotate the handwheel 11 of the first drive mechanism. The handwheel 11 drives the rotating shaft 14 and gear 12 to rotate. The gear 12 meshes with the rack 13, driving the sliding seat 7 to rise and fall along the vertical rod 9 of the support 6, changing the vertical distance between the electromagnetic coil 8 and the sample. When the sliding seat 7 moves to a suitable height, rotate the locking bolt 25 in the forward direction so that the locking bolt 25 abuts against the back of the sliding seat 7.

[0034] Horizontal distance adjustment: Start the motor 15 of the second drive mechanism. The motor 15 drives the lead screw 16 to rotate. The lead screw 16 drives the threaded block 17 to move horizontally along the crossbar 10, thereby adjusting the horizontal distance between the electromagnetic coil 8 and the sample.

[0035] When the electromagnetic coil 8 is energized, it generates a magnetic field to magnetize the sample. The magnetic susceptibility sensor 18 detects the magnetic susceptibility information of the sample and transmits it to the data processor 19 inside the base 1 via wires for processing. The processed data is then transmitted to the display screen 20 on the top of the bracket 6 via wires for display, and the operator can directly read the results.

[0036] After measurement, turn off the power, rotate the adjusting screw 4 in the opposite direction to loosen the arc clamp 3, and remove the sample. The universal wheels 23 at the bottom of the base 1 facilitate tool movement and can be locked to fix the position. The spare wires in the storage box 24 are used for component replacement, and the calibration block is used for periodic calibration of the tool to ensure measurement accuracy.

[0037] The circuits and electronic components involved, such as motors, sensors, and data processors, are all existing mature technologies. Those skilled in the art can select and adapt them according to their needs. This utility model mainly protects the mechanical structure and the linkage between the various structures, and does not involve innovative improvements to the software algorithm.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
