Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example: Reference Figure 1-Figure 6A portable rock and mineral analysis device is shown, comprising a hollow base 1 and an ore analyzer body 3, a battery 4 and a drive motor 5 are fixedly arranged on the inner wall of the bottom of the hollow base 1, the output end of the drive motor 5 is fixedly connected with a drive shaft 6, the top end of the drive shaft 6 extends to the outside of the hollow base 1 and is fixedly installed with a placement plate 7, a mounting hole is provided on the top of the hollow base 1, a vertical screw 8 is rotatably installed in the mounting hole, a synchronous transmission unit for making the vertical screw 8 rotate synchronously is connected to the drive shaft 6, a moving block 9 is threadedly sleeved on the vertical screw 8, a convenient disassembly and assembly component for fixing the ore analyzer body 3 is arranged on the moving block 9, a vertical guide unit is installed on the moving block 9, a clamping unit corresponding to the placement plate 7 is arranged on the hollow base 1, and the clamping unit is used to clamp and fix the rock and mineral sample.

[0030] By means of the above structure, through the setting of the clamping unit, the rock and mineral samples can be clamped and fixed on the placement plate 7. When the driving motor 5 is started, the driving shaft 6 will be driven to rotate. The rotation of the driving shaft 6 will drive the placement plate 7 and the rock and mineral samples to rotate together. In this process, the rotation of the driving shaft 6 will also drive the vertical screw 8 to rotate synchronously through the synchronous transmission unit. With the cooperation of the vertical guide unit, the rotation of the vertical screw 8 will drive the moving block 9 and the ore analyzer body 3 to move up and down, thereby achieving the purpose of automatically performing a comprehensive scanning and analysis of the rock and mineral samples. The staff no longer needs to manually move the ore analyzer body 3 frequently and turn over the rock and mineral samples, which saves time and effort, reduces the workload, and is simple and convenient to use, which can effectively improve work efficiency.

[0031] like Figure 2 As shown, the synchronous transmission unit includes two synchronous pulleys 10 respectively fixedly sleeved on the driving shaft 6 and the vertical screw 8, and a synchronous belt 11 is tensioned and sleeved on the two synchronous pulleys 10. The advantage of this arrangement is that when the driving shaft 6 rotates, it will drive one of the synchronous pulleys 10 to rotate, and under the action of the synchronous belt 11, it will drive the other synchronous pulley 10 to rotate together, and then drive the vertical screw 8 to rotate synchronously, and it is no longer necessary to set up an additional power source for the vertical screw 8.

[0032] In this embodiment, the vertical guide unit includes a vertical guide rod 12 fixedly mounted on the top of the hollow base 1, and the moving block 9 is slidably sleeved on the vertical guide rod 12. The top of the vertical guide rod 12 and the vertical screw rod 8 are fixedly mounted with an anti-slip block 13. The advantage of this arrangement is that, through the arrangement of the vertical guide rod 12, the moving block 9 can only move vertically up and down, and the vertical screw rod 8 will not rotate together, and the operation is stable. Through the arrangement of the anti-slip block 13, the moving block 9 can be limited and blocked to prevent the moving block 9 from accidentally falling off the vertical screw rod 8.

[0033] like Figure 3 and Figure 4As shown, the convenient disassembly and assembly component includes two clamping plates 15, a strip slide groove is opened on the top of the moving block 9, the two clamping plates 15 are slidably installed in the strip slide groove, and a two-way screw rod 14 is rotatably installed on the inner walls on both sides of the strip slide groove that are away from each other. The two clamping plates 15 are threadedly sleeved on the two-way screw rod 14, and a rotating hole is opened on the side inner wall of the strip slide groove. A control rotating rod 16 is rotatably installed in the rotating hole, one end of the control rotating rod 16 is connected to a gear transmission unit for making the two-way screw rod 14 rotate synchronously, and the other end of the control rotating rod 16 is fixedly installed with a control knob 17, and a locking unit for fixing the control knob 17 is installed on the moving block 9. The advantage of such a configuration is that when the control knob 17 is rotated, the control lever 16 will be driven to rotate, and the rotation of the control lever 16 will drive the bidirectional screw 14 to rotate synchronously through the gear transmission unit, and the rotation of the bidirectional screw 14 will drive the two clamping plates 15 to move toward or away from each other at the same time, thereby achieving the purpose of clamping or loosening the ore analyzer body 3, so that the staff can hold the ore analyzer body 3 by themselves for scanning and analysis according to the actual situation, further improving the applicability of the device.

[0034] In this embodiment, the gear transmission unit includes a first bevel gear 18 fixedly mounted on the end of the control rotating rod 16, and a second bevel gear 19 meshing with the first bevel gear 18 is fixedly sleeved on the bidirectional screw rod 14. The advantage of this arrangement is that when the control rotating rod 16 rotates, the first bevel gear 18 is driven to rotate, and the rotation of the first bevel gear 18 drives the second bevel gear 19 to rotate together, and then the bidirectional screw rod 14 can be driven to rotate synchronously, playing a transmission role.

[0035] In this embodiment, the sides of the two clamping plates 15 close to each other are both fixed with protective pads 20. The advantage of such a configuration is that the protective pads 20 can play a buffering and protective role on the ore analyzer body 3 when clamped and fixed.

[0036] like Figure 5 As shown, the locking unit includes a fixed protrusion 21 fixedly mounted on the side of the moving block 9, a horizontal sliding hole is provided on the side of the fixed protrusion 21, a horizontal plug rod 22 is slidably installed in the horizontal sliding hole, a plurality of locking holes 23 are evenly provided on the circumferential side of the control knob 17, one end of the horizontal plug rod 22 extends into one of the locking holes 23, an unlocking pull block 24 is fixedly mounted on the other end of the horizontal plug rod 22, and a reset element is installed on the horizontal plug rod 22. The advantage of such a setting is that when the unlocking pull block 24 is moved, the horizontal plug rod 22 will be driven to move in or out of the locking hole 23, and then the control knob 17 can be locked and cannot be rotated or released, so that during use, the loosening and falling off of the ore analyzer body 3 caused by the self-rotation of the control knob 17 can be effectively reduced, and the stability during use is good.

[0037] In this embodiment, the reset element includes a first protruding piece fixedly sleeved on the horizontal plug rod 22, and a reset spring 25 is sleeved on the horizontal plug rod 22. The two ends of the reset spring 25 are respectively fixedly mounted on the fixed protrusion 21 and the side of the first protruding piece. The advantage of this arrangement is that when the unlocking pull block 24 is released, the elastic force of the reset spring 25 will squeeze and push the first protruding piece to automatically reset, and then the horizontal plug rod 22 can be automatically inserted into the locking hole 23, and the control knob 17 can be automatically locked, and the locked state can be maintained all the time, which is stable and reliable.

[0038] like Figure 2 As shown, the clamping unit includes an L-shaped fixing frame 26 fixedly mounted on the top of the hollow base 1, a vertical sliding hole is opened on the top of the L-shaped fixing frame 26, a vertical sliding rod 27 is slidably mounted in the vertical sliding hole, a pressing plate 28 located directly above the placement plate 7 is rotatably mounted on the bottom end of the vertical sliding rod 27, a handle block 29 is fixedly mounted on the top of the vertical sliding rod 27, a second protrusion is fixedly sleeved on the vertical sliding rod 27, an extrusion spring 30 is sleeved on the vertical sliding rod 27, and both ends of the extrusion spring 30 are respectively fixedly mounted on the bottom of the L-shaped fixing frame 26 and the top of the second protrusion. The advantage of this arrangement is that when the handle block 29 is pulled upward, the pressure plate 28 will be driven upward and away from the placement tray 7 through the vertical slide bar 27. When the handle block 29 is released, the elastic force of the extrusion spring 30 will squeeze and push the second protrusion, and the vertical slide bar 27 will automatically reset downward, thereby driving the pressure plate 28 to move downward and automatically press the rock and mineral sample to fix it on the placement tray 7, thereby preventing the rock and mineral from shaking and falling during scanning and analysis.

[0039] like Figure 1 As shown, a matching protective cover 2 is provided on the top of the hollow base 1, and a portable handle 31 is fixed on the top of the protective cover 2. The advantage of such a setting is that, through the setting of the protective cover 2 and the portable handle 31, the protective cover 2 can play a protective role to prevent the device from being damaged due to accidental collision, and the portable handle 31 can be convenient for the staff to carry.

[0040] Working principle of the present invention:

[0041] When in use, first remove the protective cover 2, pull the handle block 29 upwards, and the vertical slide bar 27 will drive the pressure plate 28 upward away from the placement tray 7, and the rock and mineral sample will be placed on the placement tray 7. Then release the handle block 29, and under the elastic force of the extrusion spring 30, the second protrusion will be squeezed and pushed, and the vertical slide bar 27 will automatically reset downward, thereby driving the pressure plate 28 to move downward and automatically press the rock and mineral sample on the placement tray 7. Then the drive motor 5 can be started, and the operation of the drive motor 5 will drive the drive shaft 6 to rotate, and the rotation of the drive shaft 6 will drive the placement The disk 7 rotates together with the rock and mineral samples. During this process, the rotation of the driving shaft 6 will also drive the vertical screw 8 to rotate synchronously through the synchronous pulley 10 and the synchronous belt 11. With the cooperation of the vertical guide rod 12, the rotation of the vertical screw 8 will drive the moving block 9 and the ore analyzer body 3 to move up and down, thereby automatically performing a comprehensive scanning and analysis of the rock and mineral samples. The staff is no longer required to manually move the ore analyzer body 3 frequently and turn over the rock and mineral samples, which saves time and effort, reduces the workload, and is simple and convenient to use, which can effectively improve work efficiency.

[0042] When the staff pulls the unlocking block 24, the horizontal plug rod 22 will be driven to move out of the locking hole 23 and the control knob 17 will be released. At this time, the control knob 17 can be rotated. The rotation of the control knob 17 will drive the control rotating rod 16 to rotate. The rotation of the control rotating rod 16 will drive the two-way screw rod 14 to rotate synchronously through the first bevel gear 18 and the second bevel gear 19. The rotation of the two-way screw rod 14 will drive the two clamping plates 15 to move towards or away from each other at the same time, thereby clamping or loosening the ore analyzer body 3, so that the staff can hold the ore analyzer body 3 by themselves for scanning and analysis according to actual conditions. After the ore analyzer body 3 is clamped and fixed, the unlocking block 24 can be directly released. Under the elastic force of the reset spring 25, the first protrusion will be squeezed and pushed to automatically reset, thereby driving the horizontal plug rod 22 to automatically insert into the locking hole 23, locking the control knob 17 and preventing it from rotating, thereby avoiding the loosening and falling off of the ore analyzer body 3 due to the rotation of the control knob 17 during use, and being stable and reliable during use.
