[0006] Preferably, the translation mechanism includes three first mounting seats arranged at equal intervals, the side ends of the first mounting seats are rotatably mounted with a first mounting shaft, the first mounting shaft is fixedly mounted with a first gear, the three first gears are provided with a translation rack engaged with the first gear, the transmission ratio of the translation rack and the first gear is:, the sample box is fixedly mounted on the translation rack, and the first bevel gear connected to the power mechanism is also fixedly mounted on the first mounting shaft located in the middle, and the first bevel gear is engaged with the third bevel gear.

[0007] The third bevel gear rotates the first bevel gear, causing the first mounting shaft and first gear in the middle to rotate, which in turn drives the translating rack to move laterally. This also drives the rotation of the remaining two first gears, with the two outer first gears supporting the translating rack. The movement of the translating rack drives the sample storage mechanism on the translating rack, allowing the sample in the sample box to be cut by the cutting mechanism as it moves. After cutting, the top surface of the sample is smooth and easy to inspect.

[0008] Preferably, the sample storage mechanism includes a shell and a sample box vertically slidably installed in the shell, the bottom end of the shell is fixedly connected to the translation rack through a mounting plate, a turntable is rotatably installed at the center of the sample box, a clamping motor for driving the turntable to rotate is provided in the sample box, the bottom end of the turntable is eccentrically connected to a crank, a slide groove is provided at the bottom end of the sample box along the radial direction of the turntable, a slider is slidably installed in the slide groove, the slider is hinged to the crank, a clamping block for clamping the sample is fixedly installed on the slider, and a gravity sensor is provided at the center of the turntable.

[0009] The clamping block and the side wall of the sample box clamp the sample. The crank slider mechanism consists of a turntable, crank, and slider.

[0011] The lifting motor drives the rotating shaft to rotate, causing the cam to rotate. The rotation of the cam changes the distance between the rotating shaft and the bottom surface of the sample box, thereby realizing the lifting and lowering of the sample box to adjust the cutting position of the sample, thereby obtaining an upper surface of appropriate size for detection.

[0012] Preferably, the cutting mechanism includes a cutting shaft mounted vertically on a workbench, a cutting blade fixedly mounted on the cutting shaft, the cutting blade positioned above the translation mechanism, and a second bevel gear fixedly mounted on the bottom end of the cutting shaft, which is in transmission connection with the power mechanism, the second bevel gear meshing with a fourth bevel gear.

The sample box is designed with a dark color as a background plate to enhance the contrast between the stone sample surface and the background for easier identification.

[0015] The infrared detection device uses the reflective module NIR-M-R2, which has a wavelength range of 900-1700nm, a built-in light source, and supports USB, UART, and Bluetooth communication, allowing integration with mobile phones for development. This module analyzes reflected light to obtain surface composition information. The universal motion accuracy must meet the marking accuracy requirements.

[0017] Each universal joint frame is a U-shaped structure with a rotation axis. When in operation, the rotation axis of the universal joint frame coincides with the rotation axis of the cross shaft. A reserved space is set in the universal joint frame. The reserved space extends in the axial and radial directions of the rotation axis to accommodate the cross shaft and avoid interference when the universal joint frame rotates.

[0018] When the universal motor is working, the output end of the universal motor drives the universal joint frame to rotate around the rotation axis of the universal joint frame, thereby achieving the purpose of providing a set angle of steering for the universal joint. The position of the infrared detection device at the bottom of the universal joint changes with the change of the universal joint angle.

[0019] An opening and closing mechanism for closing or opening the bottom end of the box body is provided on the workbench, and an opening and closing motor for driving the opening and closing mechanism is fixedly installed on the workbench.

After cutting is completed, the opening and closing mechanism opens, and the angle of the infrared detection device is adjusted through the universal joint to perform multi-point detection, improving the accuracy of the detection results.

[0022] The active motor drives the third bevel gear to rotate, the third bevel gear drives the fourth bevel gear and the first bevel gear of the translation mechanism to rotate, and the fourth bevel gear drives the second bevel gear of the cutting mechanism to rotate, so that the translation mechanism and the cutting mechanism can start and stop synchronously, the translation mechanism drives the stone sample to move, and at the same time the cutting mechanism cuts the moving stone sample.

[0023] Preferably, a dust suction fan is provided on the workbench above the cutting mechanism, and the dust suction fan is used to absorb dust generated by the cutting mechanism when cutting samples into a dust collecting box, thereby reducing the impact of dust on detection.

[0024] Preferably, a shell is provided outside the base and the workbench, and a handle is provided on the shell for easy carrying. Four elastic buffer feet are provided on the bottom end of the base to reduce shock and noise.

[0025] Preferably, the driving motor and the clamping motor are stepping motors, the driving motor is an EDSMT-2T110-060C motor, and the lifting motor and the universal motor are servo motors.

[0026] Compared with the prior art, the present invention has the following advantages: 1. In the present invention, a power mechanism is provided on the base, which drives the translation mechanism and the cutting mechanism to operate synchronously. The translation mechanism transports the stone sample along the tangential direction of the cutting blade. The cutting blade cuts the sample so that the upper surface of the sample is cut into a plane. An element analysis device is provided on the workbench. The visual sensor of the element analysis device identifies the upper surface of the stone sample, and then the infrared detection device performs infrared detection on the upper surface of the stone sample, thereby analyzing and obtaining the element content of the stone sample.

[0027] 2. The infrared detection device in the present invention is installed at the bottom end of the universal device.

[0039] Description of reference numerals: DETAILED DESCRIPTION

[0040] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0042] like Figures 1 to 9 As shown, the present invention provides a portable geochemical element analyzer, including a base 1 and a workbench 2, wherein the base 1 is provided with a translation mechanism 3, and the translation mechanism 3 is provided with a sample storage mechanism 4 for storing samples, the bottom end of the workbench 2 is provided with a cutting mechanism 5 for cutting the sample so that the upper surface of the sample is flat, the workbench 2 is provided with an element analysis device 6, and a dust isolation plate is provided on the workbench 2 between the cutting mechanism 5 and the element analysis device 6, and the base 1 is also provided with a power mechanism 7 for driving the translation mechanism 3 and the cutting mechanism 5.

[0043] In this embodiment, the translation mechanism 3 includes three first mounting seats 301 arranged at equal intervals, and the side ends of the first mounting seats 301 are rotatably mounted with a first mounting shaft 302, and the first mounting shaft 302 is fixedly mounted with a first gear 303. The three first gears 303 are provided with a translation rack 304 meshing with the first gear 303, and the transmission ratio of the translation rack 304 to the first gear 303 is 1:110. The sample box 4 is fixedly mounted on the translation rack 304, and the first bevel gear 305 connected to the power mechanism 7 is also fixedly mounted on the first mounting shaft 302 in the middle, and the first bevel gear 305 is meshed with the third bevel gear 702.

[0044] The third bevel gear 702 drives the first bevel gear 305 to rotate, causing the first mounting shaft 302 and first gear 303 located in the middle to rotate, thereby driving the translating rack 304 to move laterally. This also drives the rotation of the other two first gears 303. The two first gears 303 located on the outer sides support the translating rack 304. The movement of the translating rack 304 drives the sample storage mechanism 4 on the translating rack 304 to move, causing the sample in the sample box 402 to be cut by the cutting mechanism 5 as it moves. After cutting, the upper surface of the sample is smooth and flat, making it easy to test.

[0045] In this embodiment, the sample storage mechanism 4 includes a shell 401 and a sample box 402 vertically slidably mounted in the shell 401. The bottom end of the shell 401 is fixedly connected to the translation rack 304 through a mounting plate. A turntable 4021 is rotatably mounted at the center of the sample box 402. A clamping motor for driving the turntable 4021 to rotate is provided in the sample box 402. The bottom end of the turntable 4021 is eccentrically connected to a crank 4022. The bottom end of the sample box 402 rotates along the turntable 402. 1 is provided with a slide groove 4023 in the radial direction, and a slider 4024 is slidably installed in the slide groove 4023. The slider 4024 is hinged to the crank 4022, and a clamping block 4025 for clamping the sample is fixedly installed on the slider 4024. The clamping block 4025 is set to an arc surface on the side facing the turntable 4021, which is convenient for clamping irregular stone samples. A gravity sensor 4026 is provided at the center of the turntable 4021 for monitoring whether a stone sample is placed on the turntable 4021.

[0046] The clamping block 4025 clamps the sample against the sidewalls of the sample box 402. The turntable 4021, crank 4022, and slider 4024 form a slider-crank mechanism. The clamping motor drives the turntable 4021 to rotate, which in turn drives the slider 4024 to move along the slide 4023, thereby driving the clamping block 4025 to move radially along the turntable 4021. This allows for adaptive adjustment based on sample size, securing the sample.

[0047] In this embodiment, a rotating shaft 4011 is rotatably installed at the bottom end of the shell 401, and a cam 4012 is fixedly installed on the rotating shaft 4011. The top of the cam 4012 is in close contact with the bottom surface of the sample box 402, and is used to drive the sample box 402 to rise and fall in the shell 401. A lifting motor for driving the rotating shaft 4011 is provided in the shell 401.

[0048] The lifting motor drives the rotating shaft 4011 to rotate, causing the cam 4012 to rotate. The rotation of the cam 4012 changes the distance between the rotating shaft 4011 and the bottom surface of the sample box 402, thereby realizing the lifting and lowering of the sample box 402 to adjust the cutting position of the sample, thereby obtaining an upper surface of appropriate size for detection.

[0049] In this embodiment, the cutting mechanism 5 includes a cutting shaft 501 vertically rotatably mounted on the workbench 2.

The second bevel gear 503 meshes with a fourth bevel gear 704. The fourth bevel gear 704 drives the second bevel gear 503 to rotate, causing the cutting shaft 501 and the cutting blade 502 to rotate. The cutting blade 502 rotates to cut the sample.

A universal device 603 is provided on the workbench 2. The infrared detection device 602 is fixedly installed at the bottom of the universal device 603. The infrared detection device 602 emits infrared rays to the sample surface through an infrared emitter, and receives reflected light through an infrared reflector, and analyzes and detects the emitted light to obtain the elemental analysis results of the sample.

[0051] The high-resolution visual sensor 601 captures the stone sample vertically downward, obtaining an image of its upper surface. The sample box is dark in color and serves as a background plate, enhancing the contrast between the stone sample surface and the background for easier identification.

[0052] Infrared detection device 602 uses the reflective module NIR-M-R2, which has a wavelength range of 900-1700nm, a built-in light source, and supports USB, UART, and Bluetooth communication, allowing integration with mobile phones for development. This module analyzes reflected light to obtain surface composition information. The universal motion accuracy must meet the marking accuracy requirements.

A reserved space is set in the universal joint frame. The reserved space extends in the axial and radial directions of the rotation axis to accommodate the cross shaft and avoid interference when the universal joint frame rotates.

[0055] When the gimbal motor 6033 is working, the output end of the gimbal motor 6033 drives the gimbal frame to rotate around the rotation axis of the gimbal frame, thereby achieving the purpose of providing a set angle of steering for the gimbal 6032. The position of the infrared detection device 602 at the bottom end of the gimbal 6032 changes with the change of the angle of the gimbal 6032.

After cutting is completed, the opening and closing mechanism 6034 opens, and the angle of the infrared detection device 602 is adjusted via the universal joint 6032 to perform multi-point detection, improving the accuracy of the detection results.

The translation mechanism 3 drives the stone sample to move, and at the same time, the cutting mechanism 5 cuts the moving stone sample.

[0060] In this embodiment, a dust suction fan 201 is provided on the workbench 2 above the cutting mechanism 5. The dust suction fan 201 is used to absorb dust generated by the cutting mechanism 5 when cutting the sample into a dust collecting box, thereby reducing the impact of dust on detection.
