When the kiln body is operating, the cooling mechanism is automatically driven to work. Stopping sampling can disconnect the transmission to reduce energy consumption, and the adjustment state is visually displayed in cooperation with the pointer of the identification plate.

[0017] 3. The transmission sleeve of the present invention drives the camshaft through the bevel gear set, making the spherical rubber rod strike the lower part of the sampling box, which is beneficial to reducing the residual sample material on the discharge plate.

The camshaft drives the diversion frame to vibrate to disperse the material synchronously, improving the cooling efficiency. After cooling, the material falls into the collection box through the diversion path. This design realizes the automatic cooling and dispersion treatment of the material after sampling, avoids sample caking and accelerates heat exchange, providing pretreatment support for subsequent detection.

[0020] Please refer to Figures 1 to 3 This invention provides a technical solution: A sampling device for detecting a lithium ore rotary kiln, including a fixed sleeve 1 and a sampling assembly 4. The inside of the fixed sleeve 1 is rotatably connected to a kiln body 2, and a sampling box 3 is arranged at the bottom of the fixed sleeve 1. The sampling assembly 4 is arranged at the lower part of the fixed sleeve 1, and the sampling assembly 4 includes a worm 401. The outer peripheral surface of one end of the worm 401 is meshed with a worm gear 402, and a crankshaft 403 is arranged inside the worm gear 402. A cam ring 404 is fixed to the outside of one end of the crankshaft 403, and a limit plate 405 is slidably connected to the top of the cam ring 404. Telescopic rods 406 are symmetrically arranged at both ends of the bottom of the limit plate 405, and the telescopic rods 406 are fixedly connected to the sampling box 3. Connecting plates 407 are slidably connected to the inside of both ends of the limit plate 405, and the connecting plates 407 are rotatably connected to the fixed sleeve 1. A pulley seat 408 is arranged at the top of the limit plate 405, and a T-shaped plate 409 is arranged at the top of the pulley seat 408. A guide plate 410 is slidably connected to the outside of the middle part of the T-shaped plate 409, and a connecting ear 411 is slidably connected to one end of the T-shaped plate 409, and a sealing plate 412 is fixed to the side part of the connecting ear 411. The guide plate 410 is fixedly connected to the kiln body 2, and the sealing plate 412 is rotatably connected to the kiln body 2, and the sealing plates 412 are evenly distributed in a circumferential direction along the inner peripheral surface of the kiln body 2; The specific operation is as follows: the sampling device is integrated at multiple positions on the rotary kiln. When sampling and analysis are required during the lithium ore production process, it is only necessary to rotate the worm 401 at the designated position to drive the crankshaft 403 to rotate through the worm gear 402, and rotate the cam ring 404 to the bottom of the limit plate 405. At this time, the limit plate 405 will move downward under the action of gravity, and the blocking of the pulley seat 408 will be released. The T-plate 409 will not support the sealing plate 412, so that when the sealing plate 412 is located at the upper part of the sampling box 3, it will automatically rotate to the open state, so that part of the material at this place can fall into the sampling box 3, and in the process of the limit plate 405 moving downward, it will also pull the connecting plate 407 so that it is on the limit plate The end of 405 slides inward to connect the limit plate 405 with the fixed sleeve 1. Therefore, when the kiln body 2 drives the T-plate 409 to move synchronously through the guide plate 410 during rotation, the inclined connecting plate 407 is used to ensure that the pulley seat 408 can slide to the inside of the fixed sleeve 1, so that the sealing plate 412 is automatically closed to avoid heat leakage. After sampling, the worm 401 is rotated again. Similarly, the convex part of the cam ring 404 can squeeze the bottom of the limit plate 405 to move it upward, and the T-plate 409 will push the sealing plate 412 through the connecting ear 411 to close the kiln body 2. After closing, its inner side will be flush with the inside of the kiln body 2 to avoid material accumulation, which is conducive to maintaining the stable operation of the normal operation of the kiln body 2.

[0021] See also Figure 1 , Figures 4 to 6 A pointer 5 is fixed to one end of the crankshaft 403, and an identification plate 6 is slidably connected to one side of the pointer 5. The identification plate 6 is rotatably connected to the worm 401, and the identification plate 6 is fixedly connected to the sampling box 3. A linkage assembly 7 is connected to the middle of the crankshaft 403, and the linkage assembly 7 includes a connecting rod 701. The middle of the crankshaft 403 is rotatably connected to the connecting rod 701, and the end of the connecting rod 701 is rotatably connected to the driving column 702. The end of the driving column 702 is fixedly connected to the discharge plate 703, and the discharge plate 703 is slidably connected to the sampling box 3. The other end of the crankshaft 403 A fixed column 704 is arranged, and a lifting slot plate 705 is slidably connected to the outer side of the fixed column 704, and a transmission rod 706 is rotatably connected to one end of the lifting slot plate 705, and a bracket 707 is slidably connected to the middle of the transmission rod 706, and the bracket 707 is fixedly connected to the sampling box 3, and a gear shaft 708 is rotatably connected to one end of the bracket 707, and a gear ring 709 is meshed with the top of the gear shaft 708, and the gear ring 709 is fixedly connected to the kiln body 2, and a rubber plate 710 is fixed to the lower end of the gear shaft 708 and the top of the transmission rod 706; The specific operation is as follows. When the cam ring 404 rotates counterclockwise to open the upper sealing plate 412, the crankshaft 403 rotates counterclockwise, causing the connecting rod 701 to push the driving column 702, thereby driving the discharge plate 703 to slide inside the sampling box 3, making the inside of the sampling box 3 closed. Therefore, during the sampling process, the overall airtightness can be maintained, reducing the heat leakage from the kiln body 2, which is beneficial to maintaining the temperature stability inside the kiln body 2. During this process, the fixed column 704 will rotate to the lower part, so that there is no transmission between the gear shaft 708 and the transmission rod 706. After sampling, when the worm wheel 402 is continuously rotated to close the sealing plate 412, the driving column 702 will be pulled by the connecting rod 701, making the discharge plate 703 in an open state. Therefore, the accumulated materials inside can be discharged for subsequent cooling-related operations. At the same time, the fixed column 704 will also rotate to the upper part, driving the lifting groove plate 705 to move upward along the outer side of the lower column of the bracket 707, making the rubber plates 710 at the ends of the transmission rod 706 and the gear shaft 708 fit tightly, so as to utilize the friction for transmission. Therefore, during the rotation of the kiln body 2, the lower cooling mechanism will be automatically driven to work. After sampling, the worm 401 can also be rotated to lower the height of the fixed column 704. Therefore, the transmission operation can be disconnected when not in use, reducing the load energy consumption. And when the crankshaft 403 rotates, it will also drive the pointer 5 to slide on the identification plate 6, and the control state at this time can be conveniently observed through the identification plate 6.

[0022] Please refer to Figure 1 、 Figures 5 to 7 As shown in FIGS. 3 and 4, a cooling component 8 is provided at the bottom of the sampling box 3, and a collection box 9 is connected to the bottom of the cooling component 8. The cooling component 8 includes a cooling box 801. The cooling box 801 is installed at the bottom of the sampling box 3. One side of the cooling box 801 is provided with a wind hood 802. A transmission sleeve 803 is rotatably connected to the middle of the wind hood 802. The transmission sleeve 803 is slidably connected to the transmission rod 706. A fan blade 804 is provided at the lower end of the transmission sleeve 803. A bevel gear set 805 is provided on the outer side of the middle of the transmission sleeve 803. One end of the bevel gear set 805 is connected to a camshaft 806. The camshaft 806 is rotatably connected to the sampling box 3. A spherical rubber rod 807 is fixed on the outer peripheral surface of the middle of the camshaft 806. The two ends of the bottom of the camshaft 806 are connected to a roller seat 808. A diversion frame 809 is installed at the bottom of the roller seat 808. The bottom of the roller seat 808 is connected to a spring seat 810. The spring seat 810 is fixed to the cooling box 801. A shunt orifice plate 811 is installed on one side of the cooling box 801. The shunt orifice plate 811 is fixed to the wind hood 802. The shunt orifice plate 811 is connected to the inside of the wind hood 802 through a pipeline. Filter plates 812 are installed inside both sides of the cooling box 801. A gas collection hood 813 is connected to the other side of the cooling box 801; The specific operation is as follows. When the transmission rod 706 rotates, it will also drive the transmission sleeve 803 to rotate, and then drive the camshaft 806 to rotate through the bevel gear set 805, so that the flexible ball head rubber rod 807 strikes the lower part of the sampling box 3, reducing the material residue on the discharge plate 703. Then the material will fall onto the diversion frame 809 and gradually fall along the inclined partition plate inside the diversion frame 809, which is beneficial to extending the residence time of the sample material inside the cooling box 801. During this process, the transmission sleeve 803 will drive the fan blade 804 to rotate, making the air flow inside the air hood 802 evenly blown into the cooling box 801 under the diversion of the diversion orifice plate 811 and discharged from the air collecting hood 813 through the filter plate 812, so as to centrally collect and process the heat and waste gas after heat exchange. And the spring seat 810 will push the diversion frame 809, making the roller seat 808 always fit the camshaft 806. Therefore, during the rotation of the camshaft 806, the diversion frame 809 can vibrate up and down, enabling the internal material to fall normally and also dispersing the material, improving the effect during heat exchange and cooling. And the material after cooling will fall into the collection box 9. Therefore, during the sampling process, the sample material will be automatically cooled, facilitating the normal progress of subsequent detection tests.

[0023] In summary, for this sampling device for lithium ore rotary kiln detection, when in use, first, when sampling at a specified location of the rotary kiln, first rotate the worm 401 at the specified location, which drives the crankshaft 403 to rotate through the worm gear 402, and rotate the cam ring 404 counterclockwise to the bottom of the limit plate 405. At this time, the limit plate 405 will move downward under the action of gravity, removing the blockage of the pulley seat 408, and the T-shaped plate 409 will no longer support the sealing plate 412. When the sealing plate 412 is located above the sampling box 3, it will automatically rotate to the open state. Therefore, part of the material at this location can fall into the sampling box 3, and the crankshaft 403 will also drive the pointer 5 to slide on the identification plate 6 during rotation, facilitating the observation of the control state at this time through the identification plate 6; Secondly, the crankshaft 403 will drive the connecting rod 701 to push the driving column 702 due to counterclockwise rotation, thereby driving the discharge plate 703 to slide inside the sampling box 3, making the inside of the sampling box 3 in a closed state. Therefore, during the sampling process, the overall tightness can also be maintained, reducing the heat leakage from the kiln body 2. During this process, the fixed column 704 will rotate to the lower part, so that there is no transmission between the gear shaft 708 and the transmission rod 706; Then, during the downward movement of the limit plate 405, it will also pull the connecting plate 407 to slide inside the end of the limit plate 405 to connect the limit plate 405 and the fixed sleeve 1. Therefore, when the kiln body 2 drives the T-shaped plate 409 to move synchronously through the guide plate 410 during rotation, the inclined connecting plate 407 is used to ensure that the pulley seat 408 can slide to the inside of the fixed sleeve 1, making the sealing plate 412 automatically close; Then, after sampling, the worm 401 is rotated again. Similarly, the convex part of the cam ring 404 can squeeze the bottom of the limit plate 405 to move it upward. The T-shaped plate 409 will then push the sealing plate 412 through the connecting ear 411 to close the kiln body 2. After closing, its inner side will be flush with the inside of the kiln body 2 to avoid material accumulation. At the same time, the connecting rod 701 will pull the driving column 702, making the discharge plate 703 in an open state. Therefore, the accumulated material inside can be discharged. During this process, the fixed column 704 will also rotate to the upper side, driving the lifting groove plate 705 to move upward along the outer side of the lower column of the bracket 707, making the rubber plates 710 at the ends of the transmission rod 706 and the gear shaft 708 fit tightly, so as to utilize the friction for transmission. Therefore, during the rotation of the kiln body 2, the transmission rod 706 will be driven to rotate through the gear ring 709, the gear shaft 708, and the rubber plates 710, causing the transmission sleeve 803 to rotate, and then driving the camshaft 806 to rotate through the bevel gear set 805, making the flexible ball head rubber rod 807 strike the lower part of the sampling box 3 to reduce the material residue on the discharge plate 703; Finally, the material will fall onto the diversion frame 809 and gradually fall along the inclined partition plate inside the diversion frame 809. During this process, the transmission sleeve 803 will drive the fan blade 804 to rotate, making the air flow inside the wind hood 802 evenly blown into the cooling box 801 through the diversion of the diversion orifice plate 811 and discharged from the air collecting hood 813 through the filter plate 812, so as to centrally collect and process the heat and waste gas after heat exchange. And the spring seat 810 will push the diversion frame 809, making the roller seat 808 always fit the camshaft 806. Therefore, during the rotation of the camshaft 806, the diversion frame 809 can be vibrated up and down, enabling the internal material to fall normally. And the cooled material will fall into the collection box 9. Therefore, during the sampling process, the sample material will be automatically cooled, facilitating the normal progress of subsequent detection tests. And after sampling, the worm 401 can be rotated to lower the height of the fixed column 704. Therefore, the transmission operation can also be disconnected when not in use, reducing the load energy consumption.
