Description

Technical Field

[0001] The present invention belongs to the technical field of ore detection, and in particular relates to an ore body alteration analysis device and method. Background Art

[0002] Ore alteration analysis is a crucial component of geological exploration and mineral development. It involves the study of physical and chemical changes occurring in ores and surrounding rocks. These changes are often associated with hydrothermal activity, magmatic activity, or other geological processes. Handheld ore analyzers are currently the most commonly used instruments for ore alteration analysis.

[0003] A Chinese patent (authorization publication number CN215894437U) discloses a handheld ore analyzer. By providing a bracket, samples can be supported and placed, which improves the detection accuracy of the analyzer. It also has the effect of supporting and placing samples, reducing contact between personnel and samples and improving personnel safety during analysis. By providing a positioning plate and elastic parts, the sample can be further positioned and clamped, thereby improving the stability of the sample placed on the connecting plate, reducing the possibility of sample shaking, and further improving the safety of the analyzer when in use.

[0004] Although the above device can elastically fix the ore in front of the detection part of the handheld ore analyzer, since the two positioning plates are slidably connected to the inner wall of the slide groove through sliders, the inspector needs to move the two positioning plates in opposite directions at the same time before placing the ore between the two positioning plates. During this process, the staff needs to simultaneously perform three steps of holding the handheld ore analyzer, moving the two positioning plates and placing the ore. At this time, it is difficult for the inspector to complete the ore fixing detection operation alone, which increases the use burden of the inspector. Summary of the Invention

[0005] Based on this, it is necessary to provide an ore alteration analysis device and method to address the problem that existing handheld ore analyzers with the function of quickly fixing ore are difficult for one person to complete, thereby reducing the convenient use function of the handheld ore analyzer.

[0006] An ore body alteration analysis device provided by the present invention includes a handheld ore analyzer, and an adjustable clamping mechanism is fixedly connected to the lower surface of the handheld ore analyzer; the adjustable clamping mechanism includes a rotating assembly fixedly connected to the lower surface of the handheld ore analyzer, and the bottom of the rotating assembly is fixedly connected to a distance adjustment assembly, one end of the distance adjustment assembly is fixedly connected to a longitudinal adjustment assembly, and one end of the longitudinal adjustment assembly is fixedly connected to a transverse adjustment assembly, the structures of the distance adjustment assembly, the longitudinal adjustment assembly and the transverse adjustment assembly are all the same, and one end of the transverse adjustment assembly is fixedly connected to the clamping assembly.

[0007] In one of the embodiments, the inspector can use an adjustable clamping mechanism to clamp the ore and flip the ore into place in sequence with one hand, without the need for multiple people to cooperate in the operation. This effectively solves the problem that the existing handheld ore analyzer with the function of quickly fixing the ore is difficult for one person to complete, thereby reducing the convenience of using the handheld ore analyzer.

[0008] Furthermore, the rotating assembly includes a rotating seat fixedly connected to the lower surface of the handheld ore analyzer, two positioning slots are opened inside the rotating seat, and a rotating shaft is rotatably connected inside the rotating seat. The opening center points of the two positioning slots and the center point of the rotating shaft together form a right-angled angle line, the upper surface of the rotating shaft is fixedly connected to a spring clip that is engaged with the upper positioning slot, and the lower surface of the rotating shaft is fixedly connected to a connecting block fixedly connected to the distance adjustment assembly.

[0009] In one embodiment, this enables the ore to be rotated steadily in front of the detection end of the handheld ore analyzer.

[0010] Furthermore, the distance adjustment assembly includes a threaded cylinder fixedly connected to the bottom of the connecting block, the surface of the threaded cylinder is slidably connected to a guide cylinder, the contact parts of the threaded cylinder and the guide cylinder are matching rectangles, the bottom of the guide cylinder is rotatably connected to a threaded adjustment rod, the top of the threaded adjustment rod passes through the guide cylinder and is threadedly connected to the threaded cylinder, and one end of the longitudinal adjustment assembly is fixedly connected to the guide cylinder.

[0011] In one embodiment, the distance adjustment component allows the inspector to quickly adjust the distance between the ore and the detection end of the handheld ore analyzer. This not only enables the detection of ores of different sizes, thereby expanding the scope of application of ores, but also prevents the ore from subsequently colliding with the detection end of the handheld ore analyzer, thereby protecting the handheld ore analyzer.

[0012] At the same time, the inspectors can quickly adjust the longitudinal and transverse axis positions of the ore in front of the detection end of the handheld ore analyzer through the longitudinal adjustment components and the transverse adjustment components, so that multi-point detection of ore alteration can be easily carried out without disassembling the ore, thereby improving the accuracy of ore alteration analysis.

[0013] Furthermore, the clamping assembly includes a mounting frame fixedly connected to one end of the lateral adjustment assembly, the interior of the mounting frame is rotatably connected to a bidirectional lead screw, the surfaces of the two opposite threads of the bidirectional lead screw are threadedly connected to a U-shaped clamping bar slidably connected to the mounting frame, the surface of the bidirectional lead screw is fixedly connected to a driven bevel gear, the surface of the driven bevel gear is meshedly connected to an active bevel gear, one end of the active bevel gear is fixedly connected to a rotating rod rotatably connected to the mounting frame, and one end of the rotating rod passes through the outside of the mounting frame.

[0014] In one embodiment, this enables the inspector to place the ore on top of the mounting frame and then clamp and secure it, allowing it to be quickly adjusted with one hand.

[0015] Furthermore, the vertical cross-section of the positioning groove is an isosceles triangle, and the vertical cross-section of the spring is an inverted V-shape.

[0016] In one embodiment, this can reduce the burden on the spring piece to enter and exit the positioning slot, ensuring that the inspector can easily rotate the ore.

[0017] Furthermore, a reserved groove is provided on the upper surface of the rotating seat, and both ends of the elastic piece are fixedly connected to the inside of the reserved groove.

[0018] In one embodiment, this can reserve sufficient deformation space for the spring sheet to prevent the spring sheet from being stuck between the rotating shaft and the rotating seat.

[0019] Furthermore, the partial cross-sectional shapes of the contact portions between the mounting frame and the U-shaped clamping strip are both matching rectangles.

[0020] In one embodiment, this can prevent the U-shaped clamping bar from rotating along with the bidirectional lead screw, thereby ensuring that the two U-shaped clamping bars cooperate to stably clamp the ore.

[0021] Furthermore, opposite ends of the two U-shaped clamping strips are fixedly connected with clamping pieces, and the horizontal cross-section of the clamping piece is V-shaped with the opening facing the center point of the installation frame.

[0022] In one embodiment, this can increase the clamping contact area for the ore, thereby improving the clamping stability for ores of different shapes.

[0023] Furthermore, the number of the clamping pieces is no less than ten, and the clamping pieces on both sides are staggered with each other.

[0024] In one embodiment, this can increase the clamping range of the clamping piece, further improving the clamping stability of ores of different shapes.

[0025] The present invention provides an ore body alteration analysis method implemented using the above-mentioned ore body alteration analysis equipment, and the ore body alteration analysis method specifically includes:

[0026] Selecting ore of corresponding specifications, placing the ore into the clamping assembly, and then driving the clamping assembly to firmly clamp the ore;

[0027] The top of the ore is adjusted to below the rotating assembly through the distance adjustment assembly to prevent the ore from colliding with the detection end of the handheld ore analyzer;

[0028] Rotate the rotating assembly ninety degrees, and rotate the ore to the front of the detection end of the handheld ore analyzer through the distance adjustment assembly, the longitudinal adjustment assembly, the lateral adjustment assembly, and the clamping assembly;

[0029] Manually turning on the handheld ore analyzer to enable the handheld ore analyzer to scan and detect the alteration conditions of the corresponding parts of the ore in real time, and compile the results into a digital analysis report for accurate recording;

[0030] The longitudinal adjustment component or the lateral adjustment component is adjusted as needed to change the position of the ore in front of the detection end of the handheld ore analyzer to meet the detection requirements of multi-point alteration of the ore, thereby improving the accuracy of ore alteration analysis.

[0031] The above-mentioned ore body alteration analysis equipment and method of the present invention have the following advantages and beneficial effects:

[0032] The inspector can use the adjustable clamping mechanism to clamp the ore and flip it into place with one hand, without the need for multiple people to cooperate. This effectively solves the problem that existing handheld ore analyzers with the function of quickly fixing the ore are difficult for one person to complete, thus reducing the convenience of using the handheld ore analyzer.

[0033] The distance adjustment component allows the tester to quickly adjust the distance between the ore and the detection end of the handheld ore analyzer. This not only allows the test of ores of different sizes to expand the scope of application, but also prevents the ore from colliding with the detection end of the handheld ore analyzer, thereby protecting the handheld ore analyzer.

[0034] Through the longitudinal adjustment component and the transverse adjustment component, the inspector can quickly adjust the longitudinal and transverse axis positions of the ore in front of the detection end of the handheld ore analyzer, so that multi-point detection of ore alteration can be easily carried out without disassembling the ore, thereby improving the accuracy of ore alteration analysis.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

The terms used in this description are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used in this description includes any and all combinations of one or more of the associated listed items.

[0050] The following combination Figure 1 - Figure 7 The ore body alteration analysis device and method of the present invention are described.

[0051] like Figure 1-7 As shown, in one embodiment, an ore body alteration analysis device includes a handheld ore analyzer 100, and an adjustable clamping mechanism 200 is fixedly connected to the lower surface of the handheld ore analyzer 100; the adjustable clamping mechanism 200 includes a rotating assembly fixedly connected to the lower surface of the handheld ore analyzer 100, and a distance adjustment assembly is fixedly connected to the bottom of the rotating assembly, one end of the distance adjustment assembly is fixedly connected to the longitudinal adjustment assembly 230, and one end of the longitudinal adjustment assembly 230 is fixedly connected to the transverse adjustment assembly 240. The structures of the distance adjustment assembly, the longitudinal adjustment assembly 230 and the transverse adjustment assembly 240 are all the same, and one end of the transverse adjustment assembly 240 is fixedly connected to the clamping assembly.

[0052] The handheld ore analyzer 100 is a portable device that uses spectral technology to analyze the composition of minerals and rocks. The handheld ore analyzer 100 is mainly composed of components such as an X-ray tube, a detector, a CPU, and a memory. Among them, the X-ray tube serves as an excitation source to generate X-rays, the detector is used to capture characteristic X-rays and convert them into electrical signals, the CPU is responsible for processing and analyzing these signals, and the memory is used to store analysis results and data. The working principle of the handheld ore analyzer 100 is mainly based on X-ray fluorescence spectrometry (XRF). When the sample is irradiated by X-rays, the element atoms in the sample will absorb the energy of the X-rays and excite the inner electrons to transition to high energy levels. Subsequently, when the outer electrons transition back to low energy levels, characteristic X-rays are released. The energy and wavelength of these characteristic X-rays are related to the type of element. Therefore, these characteristic X-rays can be captured by the detector and converted into electrical signals for analysis, thereby determining the type and content of the element in the sample.

[0053] like Figure 3 、 Figure 4 and Figure 7 As shown, the rotating assembly includes a rotating base 211 fixedly connected to the lower surface of the handheld ore analyzer 100, and two positioning grooves 212 are opened inside the rotating base 211. The rotating base 211 is rotatably connected to the inside of the rotating base 211. The opening center points of the two positioning grooves 212 and the center point of the rotating shaft 213 together form a right-angled angle line. The upper surface of the rotating shaft 213 is fixedly connected to a spring piece 214 that is engaged with the upper positioning groove 212, and the lower surface of the rotating shaft 213 is fixedly connected to a connecting block 215 that is fixedly connected to the distance adjustment assembly; the vertical cross-section of the positioning groove 212 is an isosceles triangle, and the vertical cross-section of the spring piece 214 is an inverted V shape; the upper surface of the rotating base 211 is opened with a reserved groove 216, and both ends of the spring piece 214 are fixedly connected to the inside of the reserved groove 216.

[0054] When the inspector needs to rotate the ore fixed in the clamping assembly, the inspector only needs to rotate the connecting block 215, and the connecting block 215 drives the rotating shaft 213 to rotate. The rotation of the rotating shaft 213 pulls the spring piece 214, and the spring piece 214 rotates out of the positioning groove 212 connected to it under the action of the rotating extrusion force. When the rotating shaft 213 rotates ninety degrees, the spring piece 214 is just aligned with another positioning groove 212. At this time, the spring piece 214 loses its obstruction, and the spring piece 214 elastically returns to its original shape and is clamped together with the positioning groove 212, locking the ore at the corresponding angle.

[0055] like Figure 3 、 Figure 4 and Figure 5 As shown, the distance adjustment assembly includes a threaded cylinder 221 fixedly connected to the bottom of the connecting block 215, and the surface of the threaded cylinder 221 is slidably connected to the guide cylinder 222. The contact parts of the threaded cylinder 221 and the guide cylinder 222 are both matching rectangles. The bottom of the guide cylinder 222 is rotatably connected to the threaded adjustment rod 223, and the top of the threaded adjustment rod 223 passes through the guide cylinder 222 and is threadedly connected to the threaded cylinder 221. One end of the longitudinal adjustment assembly 230 is fixedly connected to the guide cylinder 222.

[0056] With the clamping assembly in a horizontal state as the initial state, when the inspector needs to prevent the ore from colliding with the lens of the handheld ore analyzer 100 after rotation, the inspector can observe whether the top height of the ore is higher than the rotating assembly. If the ore is higher than the rotating assembly, the inspector can rotate the threaded adjustment rod 223 in the corresponding direction. The threaded adjustment rod 223 drives the guide cylinder 222 along the threaded cylinder 221 to descend along the rectangular surface of the threaded cylinder 221. The threaded cylinder 221 drives the longitudinal adjustment assembly 230 to descend. The longitudinal adjustment assembly 230 drives the lateral adjustment assembly 240 to descend. The lateral adjustment assembly 240 drives the clamping assembly to descend. The clamping assembly drives the ore to descend until the ore is lowered to the bottom of the rotating assembly.

[0057] Since the structures of the distance adjustment component, the longitudinal adjustment component 230 and the transverse adjustment component 240 are the same, when the inspector needs to adjust the transverse and longitudinal positions of the ore, the inspector only needs to adjust the longitudinal adjustment component 230 and the transverse adjustment component 240 according to the adjustment method of the above-mentioned distance adjustment component to adjust the position of the ore accordingly, so that multi-point detection of ore alteration can be easily performed without disassembling the ore, thereby improving the accuracy of ore alteration analysis.

[0058] like Figure 3 、 Figure 4 and Figure 6As shown, the clamping assembly includes a mounting frame 251 fixedly connected to one end of the lateral adjustment assembly 240, and a bidirectional lead screw 252 is rotatably connected inside the mounting frame 251. The two oppositely threaded surfaces of the bidirectional lead screw 252 are threadedly connected to a U-shaped clamping bar 253 that is slidably connected to the mounting frame 251. A driven bevel gear 254 is fixedly connected to the surface of the bidirectional lead screw 252, and a driving bevel gear 255 is meshedly connected to the surface of the driven bevel gear 254. One end of the driving bevel gear 255 is fixedly connected to a rotating rod 256 that is rotatably connected to the mounting frame 251, and one end of the rotating rod 256 passes through the outside of the mounting frame 251; the local cross-sectional shape of the contact part between the mounting frame 251 and the U-shaped clamping bar 253 is a matching rectangle; the opposite ends of the two U-shaped clamping bars 253 are fixedly connected to clamping pieces 257, and the horizontal cross-sectional shape of the clamping pieces 257 is a V-shape with the opening facing the center point of the mounting frame 251; the number of clamping pieces 257 is not less than ten, and the clamping pieces 257 on both sides are staggered with each other.

[0059] After the inspector places the ore on the top of the installation frame 251 between the clamping pieces 257 on both sides, the inspector only needs to rotate the rotating rod 256 in the corresponding direction. The rotating rod 256 drives the active bevel gear 255 to rotate, and the active bevel gear 255 drives the driven bevel gear 254 to rotate. The driven bevel gear 254 drives the bidirectional lead screw 252 to rotate. The bidirectional lead screw 252 drives the two U-shaped clamping bars 253 to move toward each other along the installation frame 251 through two opposite threads. The two U-shaped clamping bars 253 correspondingly drive the clamping pieces 257 to interlock and clamp the ore, thereby firmly locking the ore on the top of the installation frame 251.

[0060] Use as Figure 1-7 The specific process of the ore body alteration analysis method implemented by the above-mentioned ore body alteration analysis equipment is as follows:

[0061] Select the ore of corresponding specifications, place the ore into the clamping assembly, and then drive the clamping assembly to firmly clamp the ore;

[0062] The top of the ore is adjusted to below the rotating assembly through the distance adjustment assembly to prevent the ore from colliding with the detection end of the handheld ore analyzer 100;

[0063] Rotate the rotating assembly ninety degrees, and rotate the ore to the front of the detection end of the handheld ore analyzer 100 through the distance adjustment assembly, the longitudinal adjustment assembly 230, the transverse adjustment assembly 240 and the clamping assembly;

[0064] Manually start the handheld ore analyzer 100 to enable the handheld ore analyzer 100 to scan and detect the alteration of the corresponding part of the ore in real time, and compile it into a digital analysis report for accurate recording;

[0065] The longitudinal adjustment component 230 or the transverse adjustment component 240 is adjusted as needed to change the position of the ore in front of the detection end of the handheld ore analyzer 100 to meet the detection requirements of multi-point alteration of the ore, thereby improving the accuracy of the ore alteration analysis.

[0066] Working principle: With the clamping assembly in a horizontal state as the initial state, the inspector holds the handle of the handheld ore analyzer 100 with one hand, then places the ore of corresponding specifications into the clamping assembly, and then drives the clamping assembly to fix the ore. Finally, the inspector only needs to drive the rotating assembly to rotate upward ninety degrees, and rotate the ore to the front of the detection end of the handheld ore analyzer 100 through the distance adjustment assembly, longitudinal adjustment assembly 230, lateral adjustment assembly 240 and clamping assembly. At this time, the inspector can manually turn on the handheld ore analyzer 100 to detect and analyze the alteration of the ore. In the above process, the inspector can easily complete the installation and detection of the ore by one person, and does not require the cooperation of multiple people, thereby reducing the burden of ore alteration analysis.

[0067] It should be noted that the handheld ore analyzer 100 and the bidirectional screw 252 in the above description are relatively mature devices in existing technology applications. The specific model can be selected according to actual needs. At the same time, the handheld ore analyzer 100 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0068] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
