Description

Technical Field

[0001] This application relates to the field of ore processing technology, and in particular to an ore sampling device. Background Technology

[0002] Currently, the mining industry occupies a pivotal position in the national economy, and the quality of ore raw materials is the core element in this process. It is directly related to the production, operation and economic benefits of enterprises that rely on ore as raw materials. In the ore processing process, implementing random sampling and testing is a key step to ensure that the ore quality meets the standards.

[0003] In related technologies, ore sampling and testing are mostly carried out manually during the transportation process. The sampled ore is then sent to a crusher for crushing in preparation for subsequent testing and analysis. However, this manual sampling method is not only time-consuming and labor-intensive, resulting in low work efficiency, but also makes it difficult to avoid subjective selection of easily graspable ores during manual sampling, thereby destroying the randomness of sampling and seriously affecting the accuracy of ore testing results.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] This application provides an ore sampling device that solves the problem in related technologies where manual ore sampling is time-consuming, labor-intensive, inefficient, and prone to randomness, which affects the accuracy of ore testing results.

[0055] Please see Figures 1-5A ore sampling device includes: a frame 1, a shell 2, a first crushing component 3, a material distribution plate 4, a second crushing component 5, a first driving component 6, a receiving tray 7, a second driving component 8, a cover plate 9, and a third driving component 10. The upper end of the frame 1 is provided with an inclined material drop plate 11, and the material drop plate 11 has a material inlet 12. The shell 2 is provided on the frame 1. The upper end of the shell 2 has an opening 21 corresponding to the material inlet 12. The shell 2 is vertically provided with a partition 22. The lower end of the shell 2 has a material outlet 23 and a slag discharge port 24. The material outlet 23 and the slag discharge port 24 are respectively provided on both sides of the partition 22.

[0056] The first crushing assembly 3 includes two sets of pressing rollers 31 and two sets of inclined plates 32. The two sets of pressing rollers 31 are rotatably disposed inside the housing 2 and are located above the partition plate 22. The two sets of inclined plates 32 are symmetrically disposed on both sides of the inside of the housing 2 and are respectively located above the two sets of pressing rollers 31. The material distribution plate 4 is disposed inside the housing 2 and is located between the pressing rollers 31 and the partition plate 22. The material distribution plate 4 is located between the two sets of pressing rollers 31. The second crushing assembly 5 includes a roller shaft 51, two sets of guard plates 52 and several crushing rods 53. The roller shaft 51 is rotatably disposed inside the housing 2 and is located on one side of the partition plate 22. Several crushing rods 53 are evenly disposed in a ring on the roller shaft 51. The two sets of guard plates 52 are respectively located on both sides of the roller shaft 51. One set of guard plates 52 is disposed on the inner wall of the housing 2 and the other set of guard plates 52 is disposed on the side of the partition plate 22 near the roller shaft 51.

[0057] The first driving component 6 is disposed on the housing 2 and connected to the roller shaft 51 and two sets of pressure rollers 31 to drive the roller shaft 51 and the two sets of pressure rollers 31 to rotate. The receiving plate 7 is slidably disposed in the housing 2 and is located below the roller shaft 51. The receiving plate 7 corresponds to the discharge port 23. The second driving component 8 is disposed on the housing 2 and connected to the receiving plate 7 to drive the receiving plate 7 to move closer to or away from the discharge port 23. The cover plate 9 is rotatably disposed on the housing 2 and is located in the opening 21. The third driving component 10 is disposed in the housing 2 and connected to the cover plate 9 to drive the cover plate 9 to rotate.

[0058] In this way, the frame 1 can be placed in the ore processing production line, with the dropping plate 11 positioned between two conveying devices. When the ore moves from one conveying device to the next, it falls onto the dropping plate 11 and moves along the inclined plate. During the conveying process, the third drive assembly 10 drives the cover plate 9 to rotate downwards, opening the feed inlet 12 so that the ore falls into the housing 2 through the opening 21. Then, the first drive assembly 6 drives the roller shaft 51 and two sets of... The pressure roller 31 rotates, thereby initially crushing the ore falling into the shell 2 through the two sets of pressure rollers 31. At the same time, after the feed inlet 12 is open for a period of time, the third drive component 10 will drive the cover plate 9 to rotate upward and reset. In this way, the feed inlet 12 can be blocked by the cover plate 9 to prevent the ore from entering the shell 2. In this way, the cover plate 9 is intermittently rotated by the third drive component 10, which not only allows for random sampling of ore from different areas to enhance the randomness of sampling, but also prevents a large amount of ore from entering the shell 2 at one time, which would cause blockage and affect the crushing effect.

[0059] After the initial crushing of the ore, it passes through two sets of pressure rollers 31 and continues to fall. It will be separated to both sides of the partition plate 22 by the separation effect of the distribution plate 4, so as to further divide and sample the crushed ore. This not only further enhances the randomness of sampling, but also avoids the fact that the local ore content is too high after large pieces of ore are crushed, which will affect the accuracy of ore testing. Furthermore, dividing the crushed ore can reduce the sample quality, reduce sampling costs, and avoid the inconvenience of too many samples for the staff to operate.

[0060] Then, the ore falling into the slag discharge port 24 will be discharged directly out through the slag discharge port 24, while the ore falling into the discharge port 23 will fall onto the crushing rod 53. In this way, the roller 51 continuously drives the crushing rod 53 to rotate, so that the crushing rod 53 can continuously impact the falling ore and push the ore towards the two sets of guard plates 52. This allows the high-speed moving ore to come into contact with the crushing rod 53 and the guard plates 52 to further crush the ore. In this way, the crushing quality of the ore can be guaranteed by secondary crushing of the ore, so as to ensure the consistency of ore sampling.

[0061] The crushed ore then continues to fall, and the second drive component 8 drives the receiving plate 7 to move, causing the receiving plate 7 to continuously extend and retract from the discharge port 23 into the housing 2. When the receiving plate 7 extends into the housing 2, it catches some of the falling ore, and then moves into the discharge port 23 to discharge the ore outward through the discharge port 23. Then, the staff can obtain a sample of the crushed ore. At the same time, the ore that is not collected will continue to be discharged through the slag discharge port 24. In this way, the continuously extending and retracting receiving plate 7 can be used to intermittently sample the crushed ore, which can further reduce the content of the ore sample and ensure randomness. By secondary crushing, material distribution, and small-scale cyclic sampling of the ore, the randomness and uniformity of ore sampling can be enhanced, avoiding the influence of different ore sizes and contents on the accuracy of ore testing and causing errors during the sampling process. This ensures the accuracy of ore sampling and testing, and at the same time, it eliminates the need for manual sampling, saving time and labor, making it easy to use and highly practical.

[0062] Please see Figure 6 In this embodiment, the first drive assembly 6 includes a motor 61, a first transmission belt 62, a second transmission belt 63, a first transmission wheel 64, a second transmission wheel 65, two sets of third transmission wheels 66, and two sets of gears 67. The motor 61 is mounted on the frame 1. The first transmission wheel 64 is mounted on the output end of the motor 61. The second transmission wheel 65 is mounted on one end of the roller shaft 51. The two sets of gears 67 are respectively mounted on two sets of pressure rollers 31 and mesh with each other. The two sets of third transmission wheels 66 are respectively mounted on two sets of pressure rollers 31. The first transmission belt 62 is sleeved on the first transmission wheel 64 and one set of third transmission wheels 66. The second transmission belt 63 is sleeved on the second transmission wheel 65 and the other set of third transmission wheels 66.

[0063] In this way, when in use, the motor 61 can be started, which drives the first transmission wheel 64 to rotate. The first transmission wheel 64 then drives one of the third transmission wheels 66 to rotate via the first transmission belt 62. The third transmission wheel 66 then drives the pressure roller 31 to rotate, which in turn drives the gear 67 to rotate. This, in turn, drives the other pressure roller 31 to rotate through the meshing transmission of the two sets of gears 67. Thus, the meshing transmission of the two sets of gears 67 causes the two sets of pressure rollers 31 to rotate in opposite directions to crush the ore.

[0064] Simultaneously, another pressing roller 31 will drive another third transmission wheel 66 to rotate. This third transmission wheel 66 will then drive the second transmission wheel 65 to rotate via the second transmission belt 63. In turn, the second transmission wheel 65 will drive the roller shaft 51 and several crushing rods 53 to rotate, thus performing secondary crushing of the ore. In this way, a single motor 61 can drive the two ore crushing mechanisms simultaneously. This not only reduces the driving source and lowers equipment costs, but also links the two crushing processes together, making the device more stable in operation. The structure is simple, easy to inspect and maintain, and convenient to use.

[0065] Please see Figures 9-10 The second drive assembly 8 includes a first rotating shaft 81, a fourth transmission wheel 82, a fifth transmission wheel 83, a third transmission belt 84, and two sets of first transmission components 85. The first rotating shaft 81 is rotatably disposed within the housing 2. The fourth transmission wheel 82 is sleeved on the first rotating shaft 81, the fifth transmission wheel 83 is sleeved on the roller 51, and the third transmission belt 84 is sleeved on the fourth transmission wheel 82 and the fifth transmission wheel 83. The two sets of first transmission components 85 are symmetrically arranged on both sides of the receiving tray 7. 5 includes a fixed plate 851, a guide groove 852, a first fixed post 853, a first fixed rod 854, a first connecting rod 855, a second connecting rod 856, a first connecting post 857, and two sets of first sleeves 858. The fixed plate 851 is located on one side of the receiving tray 7 and is mounted on the housing 2. The guide groove 852 is formed on the fixed plate 851 and includes a straight section 8521 and an inclined section 8522. The inclined section 8522 is located near the outlet of the straight section 8521. One end of the feed inlet 23 is connected to it. The height of the plane where the inclined section 8522 is located decreases as the distance from the discharge outlet 23 decreases. The first fixing post 853 is located at the end of the receiving plate 7 away from the discharge outlet 23, and the first fixing rod 854 is located at the end of the receiving plate 7 near the discharge outlet 23. Both the first fixing post 853 and the first fixing rod 854 are located in the guide groove 852. Both the first fixing post 853 and the first fixing rod 854 cooperate with the guide groove 852. The two sets of the first... Sleeves 858 are respectively sleeved on the first fixed post 853 and the first fixed rod 854. The two sets of first sleeves 858 are rotatably connected to the first fixed post 853 and the first fixed rod 854 respectively. The first connecting rod 855 is provided on the first rotating shaft 81. The first connecting post 857 is provided on the first connecting rod 855. One end of the second connecting rod 856 is sleeved on the first connecting rod 855 and rotatably connected to it. The other end of the second connecting rod 856 is sleeved on the first fixed rod 854 and rotatably connected to it.

[0066] When the roller 51 rotates to perform secondary crushing of the ore, the roller 51 will drive the fifth transmission wheel 83 to rotate. The fifth transmission wheel 83 will then drive the fourth transmission wheel 82 to rotate via the third transmission belt 84. The fourth transmission wheel 82 will then drive the first rotating shaft 81 to rotate. The first rotating shaft 81 will then drive the first connecting rods 855 at both ends to rotate. During the rotation of the first connecting rod 855, it will drive the second connecting rod 856 to rotate via the rotational connection between the first connecting column 857 and the second connecting rod 856. The second connecting rod 856 will then drive the first fixed rod 854 to move. At the same time, through the cooperation of the first fixed rod 854, the first fixed column 853 and the guide groove 852, the second connecting rod 856 will drive the first fixed rod 854 and the first fixed column 853 to move within the guide groove 852.

[0067] When the receiving tray 7 is in the receiving state, it will be in a horizontal position. At this time, both the first fixing rod 854 and the first fixing post 853 are located within the straight section 8521. When the second connecting rod 856 pushes the first fixing rod 854 away from the first connecting rod 855, the first fixing rod 854 will move along the straight section 8521 towards the inclined section 8522. At the same time, the first fixing rod 854 pulls the receiving tray 7 towards the discharge port 23, and the first fixing post 853 moves within the straight section 8521, thereby making the receiving tray 7 more horizontal. The material tray 7 is in a horizontal state, which moves the ore towards the discharge port 23. When the first fixing rod 854 moves into the inclined section 8522, the first fixing column 853 is located in the straight section 8521. As the first fixing rod 854 moves continuously in the inclined section 8522, the height of the horizontal plane where the first fixing rod 854 is located also decreases continuously. In this way, the first fixing rod 854 will drive the receiving tray 7 to tilt and flip downward, so that the ore falls into the discharge port 23 along the inclined receiving tray 7 for feeding.

[0068] Then, when the second connecting rod 856 drives the first fixed rod 854 to move in the opposite direction and reset, the first fixed rod 854 will continuously rise in the inclined section 8522, thereby driving the receiving plate 7 to continuously rotate upward to a horizontal state. Then, the first fixed rod 854 will cooperate with the first fixed column 853 to drive the receiving plate 7 to move into the housing 2 to collect ore for sampling. At the same time, the first sleeve 858 on the first fixed column 853 and the first fixed rod 854 can reduce the friction between the first fixed column 853 and the first fixed rod 854 and the guide groove 852, so that the first sleeve 858 can roll in the guide groove 852, making the movement of the receiving plate 7 smoother.

[0069] When the first fixed rod 854 moves into the inclined section 8522 again, it will cause the receiving plate 7 to tilt and pour out the collected ore. This cycle repeats, allowing the receiving plate 7 to continuously extend into the shell 2 to collect and sample ore, and to continuously tilt and extend into the discharge port 23 to discharge ore. This allows the receiving plate 7 to perform small-scale, multiple random samplings, which not only further enhances the randomness of ore sampling, but also reduces the driving source and lowers equipment costs by linking the movement of the receiving plate 7 with the ore crushing mechanism. At the same time, the structure is simple, easy to maintain, and can ensure stable operation of the device, making it highly practical.

[0070] The housing 2 is provided with a scraper 20, which is located above the receiving tray 7 and corresponds to the discharge port 23.

[0071] When the receiving tray 7 is full of ore and moves into the discharge port 23 for unloading, the receiving tray 7 will come into contact with the scraper 20 as it moves with the ore. This allows the scraper 20 to flatten the piled-up ore, thus preventing excessive ore sampling. The limiting effect of the scraper 20 ensures the accuracy and consistency of each sampling by the receiving tray 7, making each ore sampling more uniform and ensuring the accuracy of ore sampling and testing, while also facilitating use.

[0072] Please see Figures 7-8 In this embodiment, the third drive assembly 10 includes a second rotating shaft 101, a sixth transmission wheel 102, and a plurality of second transmission components 103. The second rotating shaft 101 is rotatably disposed within the housing 2. The sixth transmission wheel 102 is sleeved on the second rotating shaft 101 and is located within and cooperates with the first transmission belt 62. A plurality of second transmission components 103 are equidistantly disposed on the second rotating shaft 101. Each second transmission component 103 includes a first slide block 1031, a first slider 1032, a third connecting rod 1033, a second fixed post 1034, a second sleeve 1035, a first turntable 1036, a cam groove 1037, and a limiting sleeve 1038. The first slide block 1031 is disposed on the cover plate. 9. The first slider 1032 is sleeved on the first slide block 1031 and slidably connected to it. The limiting sleeve 1038 is disposed in the housing 2. The third connecting rod 1033 passes through the limiting sleeve 1038 and is slidably connected to it. The upper end of the third connecting rod 1033 is hinged to the first slider 1032. The second fixing post 1034 is disposed at the end of the third connecting rod 1033 away from the first slider 1032. The second sleeve 1035 is sleeved on the second fixing post 1034 and rotatably connected to it. The first turntable 1036 is sleeved on the second rotating shaft 101. The cam groove 1037 is opened on one side of the first turntable 1036. The second sleeve 1035 is located in the cam groove 1037 and cooperates with it.

[0073] When crushing the ore, the first transmission belt 62, in conjunction with the sixth transmission wheel 102, drives the second rotating shaft 101 to rotate. The second rotating shaft 101 then drives the first turntable 1036 to rotate, which in turn drives the cam groove 1037 to rotate. During this rotation, the cam groove 1037, in conjunction with the second fixed column 1034, drives the third connecting rod 1033 to move. Simultaneously, the second sleeve 1035 reduces the friction between the second fixed column 1034 and the cam groove 1037. Thus, during its movement, the third connecting rod 1033, through its interaction with the limiting sleeve... The limiting and guiding function of the sliding connection 1038 drives the first slider 1032 to move up and down. In this way, the first slider 1032 will drive the cover plate 9 to move through the sliding connection with the first slide block 1031. Thus, through the rotational connection between the cover plate 9 and the housing 2, the cover plate 9 will continuously rotate up and down, thereby continuously opening and closing the feed port 12 to achieve uninterrupted ore feeding. This can ensure the randomness of ore feeding. At the same time, by linking ore feeding with ore crushing, the ore crushing and feeding can be more tightly coordinated, thereby further ensuring the stability of the device during operation and making it highly practical.

[0074] Specifically, the cam groove 1037 includes a first arc segment 10371, a second arc segment 10372, and two sets of connecting segments 10373. The first arc segment 10371 and the second arc segment 10372 are arranged opposite to each other, and the two sets of connecting segments 10373 are symmetrically arranged between the first arc segment 10371 and the second arc segment 10372. The two ends of the two sets of connecting segments 10373 are respectively connected to the two ends of the first arc segment 10371 and the second arc segment 10372. The centers of the first arc segment 10371 and the second arc segment 10372 coincide, and the diameter of the first arc segment 10371 is smaller than the diameter of the second arc segment 10372.

[0075] When the second sleeve 1035 moves within the second arc segment 10372, due to the larger diameter of the second arc segment 10372, the second sleeve 1035 will drive the cover plate 9 upward to close via the third connecting rod 1033. Simultaneously, the cover plate 9 remains closed during the movement within the second arc segment 10372. When the second sleeve 1035 moves from the second arc segment 10372 into the first arc segment 10371 via the connecting section 10373, due to the smaller diameter of the first arc segment 10371, the second sleeve 1035 will pull the cover plate 9 downward to open via the third connecting rod 1033, facilitating ore sampling. Simultaneously, the second sleeve 1035... During the movement within the first arc segment 10371, the cover plate 9 remains open. When the second sleeve 1035 re-enters the second arc segment 10372 from the first arc segment 10371 via the connecting section 10373, the second sleeve 1035 will push the cover plate 9 upward to close via the third connecting rod 1033. In this way, the first turntable 1036 continuously drives the cam groove 1037 to rotate, and the cam groove 1037 will, through its cooperation with the second sleeve 1035, cause the cover plate 9 to open and close intermittently. This allows for long-distance random sampling of the ore, further ensuring the randomness of ore sampling and thus further guaranteeing the accuracy of ore sampling and testing. It is highly practical.

[0076] Furthermore, in this embodiment, the material distribution plate 4 is slidably disposed inside the housing 2, and the housing 2 is provided with a third transmission assembly 30 for driving the material distribution plate 4 to reciprocate.

[0077] Please see Figure 11 The third transmission assembly 30 is provided in two sets, symmetrically arranged at both ends of the material distribution plate 4. Each third transmission assembly 30 includes a second slide block 301, a second slider 302, a second fixed rod 303, a seventh connecting rod 304, a third fixed column 305, and a second turntable 306. The second slide block 301 is located inside the housing 2, and the second slider 302 is located inside and slidably connected to the second slide block 301. The second fixed rod 303 is located on the second slider 302. The end of the fixed rod 303 away from the second slider 302 passes through the housing 2 and extends to the outside of the housing 2. The housing 2 and the second slide block 301 are provided with through holes to facilitate the passage of the second fixed rod 303. The second turntable 306 is provided on the roller 51. The third fixed post 305 is provided on the second turntable 306. One end of the seventh connecting rod 304 is sleeved on the third fixed post 305 and rotatably connected to it. The other end of the seventh connecting rod 304 is sleeved on the second fixed rod 303 and rotatably connected to it.

[0078] When the roller 51 rotates, it drives the second turntables 306 at both ends to rotate. The second turntables 306 then pull the seventh link 304 to move through the third fixed column 305. The seventh link 304 then drives the second slider 302 to move through its rotational connection with the second fixed rod 303. At the same time, due to the limiting effect of the sliding connection between the second slider 302 and the second slide block 301, the second slider 302 drives the distribution plate 4 to move back and forth continuously to divert the falling ore. This further enhances the randomness of ore sampling, thereby ensuring the accuracy of ore sampling and testing.

[0079] By repeatedly crushing and randomly sampling the ore, the randomness of ore sampling can be greatly enhanced. At the same time, by using a motor 61 to drive the entire device, the stability of the device's operating rhythm can be further enhanced, making the device more stable and convenient to use.

[0080] More specifically, in this embodiment, the housing 2 is provided with a sieve plate 40 located below the roller shaft 51, and the sieve plate 40 is provided with a plurality of through holes 41 to facilitate the passage of the crushing rod 53;

[0081] The through holes on the screen plate 40 not only screen the crushed ore, ensuring that only ore of a certain particle size can pass through the screen plate 40 and enter the receiving tray 7, further improving the crushing effect and quality, and ensuring the sampling effect of the ore, but also, when some large pieces of ore fall on the screen plate 40, the crushing rod 53 passes through the through hole 41 during rotation, and the crushing rod 53 will further crush the ore by squeezing it in cooperation with the screen plate 40. In this way, the ore can be completely crushed before it falls onto the receiving tray 7 for sampling, which is highly practical.

[0082] Preferably, the upper end face of the cover plate 9 is provided with a collision protection plate 50;

[0083] In this way, when the ore falls onto the cover plate 9 through the feed inlet 12, the anti-collision plate 50 can shield and protect the cover plate 9, preventing the cover plate 9 from deforming due to prolonged collision between the ore and the cover plate 9, which would affect the opening and closing of the cover plate 9 and thus affect the intermittent feeding of the ore. This ensures the service life of the cover plate 9 and makes it more convenient to use.
