[0019] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0020] Unless expressly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood to include the stated elements or components but not to exclude other elements or components.

[0021] Reference Figures 1-15 As shown, this embodiment provides a technical solution: The sampling device for distinguishing the components of lead-zinc ore in the present invention comprises a parking platform 1 for parking a mine car and a driving component 2 located on the periphery of the parking platform 1. A sampling bucket component 3 for sampling lead-zinc ore powder is fixed on the driving component 2. A sample preparation component 4 for mixing the sample is fixed on the left side of the parking platform 1. During sampling, the mine car loaded with lead-zinc ore powder is parked on the parking platform 1, and then the sampling bucket component 3 is driven by the driving component 2 to perform multi-point sampling of the ore powder. After sampling is completed, the sample is sent to the sample preparation component 4 for mixing and can be taken out for inspection. The sampling hopper assembly 3 includes a hopper body 32, a material storage structure 33 fixed to the bottom of the left side wall of the hopper body 32, a feeding structure 34 provided at the connection between the hopper body 32 and the material storage structure 33, and a rotating plate structure 35 provided in the hopper body 32 to control the fall of excess mineral powder. The hopper body 32 is generally in the shape of a square platform with a small bottom and a large top, which is convenient for feeding mineral powder. The rotating plate structure 35 includes a rotating plate 351 and two second rotating shafts 352 fixed to the right ends of the front and rear side walls of the rotating plate 351. A second clamping plate 354 is coaxially fixed to the inner side wall of the second rotating shaft 352. A second spring 353 is installed on the side wall of the second rotating shaft 352 outside the second clamping plate 354. The feeding structure 34 includes a rotating rod 341 and a material receiving port 342 provided on the surface of the rotating rod 341. When no sampling is being performed, the bottom surface of the material receiving port 342 is placed horizontally. A notch 323 is provided on the left side wall of the bucket body 32 near the bottom. The rotating plate structure 35 is located below the notch 323. The rotating rod 341 is arranged in the notch 323. The front and rear ends of the rotating rod 341 are coaxially fixed with a first rotating shaft 343. A first clamping plate 345 is coaxially fixed to the inner side wall of the first rotating shaft 343. A first spring 344 is provided on the side wall of the first rotating shaft 343 outside the first clamping plate 345. When the sampling bucket assembly 3 moves downward and extends into the mineral powder, the rotating plate structure 35 is blocked by the rotating rod 341 and cannot rotate upward. When the sampling bucket assembly 3 is completely immersed in the mineral powder, the mineral powder falls from the top of the sampling bucket assembly 3 into the bucket body 32 until the material receiving port 342 is filled. The hopper body 32 is provided with iron chains 355 symmetrically front and back. One end of the iron chain 355 is fixed to the side wall of the first clamping plate 345 on the same side, and the other end is fixed to the side wall of the second clamping plate 354 on the same side. After the material filling port 342 is filled, the sampling hopper assembly 3 is pulled up. At this time, the excess mineral powder inside the hopper body 32 will exert a downward pressure on the rotating plate structure 35 due to the influence of gravity. At this time, the rotating plate 351 drives the second rotating shaft 352 and the second clamping plate 354 to rotate counterclockwise and compress the second spring 353. The counterclockwise rotation of the second clamping plate 354 will pull the first clamping plate 345 to rotate counterclockwise through the iron chain 355, and then drive the rotating rod 341 to rotate counterclockwise, so that the material filling port 342 rotates to face the material storage structure 33, so that the mineral powder is dumped into the material storage structure 33; The material storage structure 33 includes a material storage box 331 and a movable plate mechanism 332 located at the bottom of the material storage box 331 for controlling the falling of the sample. The right side of the material storage box 331 is connected to the slot 323. By setting up the material storage structure 33, when sampling at multiple points, the sample mineral powder can be temporarily stored without multiple round trips to the sample preparation component 4, thereby avoiding the dispersion of mineral powder during movement.

[0022] Among them, Figure 1-Figure 3As shown, the drive assembly 2 includes an X-axis drive structure and a Y-axis drive structure, wherein the X-axis drive structure and the Y-axis drive structure are commonly used drive devices and are not described in detail here. A hydraulic cylinder 31 is provided above the bucket body 32, and the bottom end of the output shaft of the hydraulic cylinder 31 is welded to a cross bar and the two ends of the cross bar are welded and fixed to the top surface of the bucket body 32. The top surface of the hydraulic cylinder 31 is fixed to the X-axis drive structure, and the bucket body 32 is driven up and down by the hydraulic cylinder 31. A feed port 321 is provided on the top surface of the bucket body 32. When the bucket body 32 is completely immersed in the mineral powder, the mineral powder can enter the bucket body 32 from the feed port 321. A discharge port 322 is provided at the bottom end of the bucket body 32, and excess mineral powder can leak out from the discharge port 322 to avoid waste.

[0023] Further, if Figure 3-Figure 7 As shown, the slot 323 fits closely with the rotating rod 341 to prevent mineral powder from leaking from the gap between the two. The first rotating shaft 343 is inserted into the corresponding side wall of the slot 323 and the two are hinged. The rotating plate structure 35 is arranged in the discharge port 322. It should be noted that the discharge port 322 is a square with the same upper and lower dimensions to prevent the rotating plate structure 35 from being blocked by the discharge port 322 when rotating. The second rotating shaft 352 is inserted into the corresponding side wall of the discharge port 322 and the two are hinged.

[0024] In addition, there are two first clamping plates 345 and two second clamping plates 354. The first clamping plates 345 are fixed on the inner side of the side wall corresponding to the first rotating shaft 343, and the second clamping plates 354 are fixed on the inner side of the side wall corresponding to the second rotating shaft 352. The first clamping plates 345 and the second clamping plates 354 on the same side are located in the same vertical plane. The bucket body 32 is located on the left side of the second clamping plate 354 and is provided with a guide roller 356. One end of the iron rope 355 passes through the left side of the first clamping plate 345 to the rightmost end of the first clamping plate 345, and the other end passes through the bottom of the second clamping plate 354 to the top surface of the second clamping plate 354, ensuring that when the rotating plate structure 35 rotates counterclockwise, the iron rope 355 is pulled, thereby driving the second clamping plate 354 to rotate counterclockwise synchronously.

[0025] In addition, if Figure 8-11 As shown, the movable plate mechanism 332 includes an L-shaped movable plate 3321 and a locking ball 3322 fixed to the middle of the left side wall of the vertical section of the movable plate 3321. Slide grooves are provided at the bottom ends of the front and rear outer walls of the material storage box 331, and external protrusions that match the slide grooves are provided at the front and rear edges of the movable plate 3321. The external protrusions are embedded in the corresponding slide grooves, that is, the movable plate mechanism 332 is slidably engaged with the bottom end of the material storage box 331. The movable plate mechanism 332 is pulled open by translation to open the bottom end of the material storage box 331 for discharging materials. The movable plate 3321 is fixed with a block 3323 adapted to the slide groove at the right end at the front and rear side edges. The block 3323 is fixed to the right end of the corresponding outer protrusion. A slide rod 333 is fixed between the left and right side walls of the slide groove. When the sample is sent into the sample preparation component 4, the movable plate 3321 slides to the left to facilitate the opening of the storage box 331 without manual operation by the staff. The side wall part of the slide rod 333 located between the block 3323 and the left side wall of the corresponding slide groove is covered with a return spring 334. After the movable plate 3321 leaves the sample preparation component 4, the return spring 334 pushes the movable plate 3321 to slide to the right again and close.

[0026] Among them, Figure 12-15 As shown, the sample preparation component 4 includes a sample preparation barrel 41 and a mixing structure 42 arranged in the middle of the sample preparation barrel 41. The mixing structure 42 includes a fixed sleeve 421, a rotating rod 422 arranged in the fixed sleeve 421, and a bending rod 423 fixed to the bottom end of the rotating rod 422. An overhanging plate 4222 is fixed to the side wall of the rotating rod 422 near the bottom end. An annular groove 4212 is provided at the position corresponding to the position of the inner side wall of the fixed sleeve 421 and the overhanging plate 4222. The overhanging plate 4222 is arranged in the annular groove 4212. By providing the overhanging plate 4222 and the annular groove 4212, the rotating rod 422 is supported and limited to prevent the rotating rod 422 from being suspended in the air.

[0027] Specifically, the side wall of the fixed sleeve 421 is provided with a vertical groove 4211 for the card ball 3322 to slide up and down, and the side wall of the rotating rod 422 is provided with a spiral groove 4221. The ball end of the card ball 3322 is adapted to the spiral groove 4221, and the top of the spiral groove 4221 corresponds to the top position of the vertical groove 4211. When the sampling bucket assembly 3 completes multi-point sampling, it returns to the top of the sample preparation barrel 41, and then the hydraulic cylinder 31 drives the sampling bucket assembly 3 to move downward until the card ball 3322 contacts the spiral groove 4221. Continuing to descend will drive the rotating rod 422 to rotate under the action of the spiral groove 4221. Furthermore, the bending rod 423 is in a vertical Z shape, and the vertical section above the bending rod 423 and the side wall of the bending section are provided with an outer groove 4231 toward the right side, the top of the outer groove 4231 is connected to the bottom end of the spiral groove 4221, and a number of stirring rods 424 are regularly and staggeredly fixed on the side wall of the vertical section below the bending rod 423. When the card ball 3322 continues to descend and contacts the outer groove 4231, the card ball 3322 will be pulled to the left and drive the movable plate 3321 to slide to the left, thereby opening the material storage box 331. At this time, the sample can fall into the sample preparation barrel 41. After the sample has completely fallen, the hydraulic cylinder 31 drives the sampling bucket assembly 3 to move upward. At this time, the card ball 3322 will be squeezed to the right and drive the movable plate 3321 to slide to the right, thereby closing the storage box 331. When the card ball 3322 returns to the spiral groove 4221, it will drive the rotating rod 422 to rotate again, and then drive the bending rod 423 and the stirring rod 424 below to rotate synchronously, stirring and mixing the samples sampled at multiple points. After the sampling bucket assembly 3 is completely detached, the operator can take out the mixed sample. The sampling port is not shown in the bottom view of the sample preparation barrel 41.

[0028] In addition, a number of fixing frames 43 are provided at the barrel opening of the sampling barrel 41. The top of the fixing frame 43 is fixed to the middle of the outer wall of the fixing sleeve 421. A number of regularly distributed rubber baffles 44 are fixed at the barrel opening of the sampling barrel 41. By setting the baffles 44, the mineral powder is prevented from being dispersed from the sampling barrel 41 during stirring. The fixing sleeve 421 and the rotating rod 422 are located above the baffles 44, and the bending section of the bending rod 423 is located below the baffles 44, ensuring that when the material storage box 331 is opened, the entire material storage box 331 is located below the baffles 44. During stirring, the sampling bucket assembly 3 has been completely retracted outside the sampling barrel 41.

[0029] The working principle of the sampling device for distinguishing the components of lead-zinc ore in the present invention is specifically as follows: When the lead-zinc ore composition needs to be tested, the mine car loaded with lead-zinc ore powder is parked on the parking platform 1, and then the driving component 2 is started to drive the sampling bucket component 3 to adjust its position. Then, the hydraulic cylinder 31 drives the bucket body 32 to descend until the bucket body 32 is completely immersed in the ore powder. The ore powder falls from the top of the sampling bucket component 3 into the bucket body 32 until the material holding port 342 is filled. Then, the hydraulic cylinder 31 is activated again to drive the bucket 32 ​​upward. At this time, the excess mineral powder inside the bucket 32 ​​exerts downward pressure on the rotating plate structure 35 due to the influence of gravity. At this time, the rotating plate 351 drives the second rotating shaft 352 and the second clamping plate 354 to rotate counterclockwise and compress the second spring 353. The counterclockwise rotation of the second clamping plate 354 pulls the first clamping plate 345 to rotate counterclockwise through the iron rope 355, thereby driving the rotating rod 341 to rotate counterclockwise, causing the material receiving port 342 to rotate toward the material storage structure 33 and dump the mineral powder into the material storage structure 33. After that, the driving component 2 is started again to drive the sampling bucket component 3 to reselect a sampling point, and the above operation is repeated to complete multi-point sampling; When the sample is completely dropped into the sample preparation barrel 41, the hydraulic cylinder 31 drives the sampling hopper assembly 3 to move upward, and the locking ball 3322 is squeezed to the right to drive the movable plate 3321 to slide to the right, thereby closing the sample storage box 331. When the locking ball 3322 returns to the spiral groove 4221, it will drive the rotating rod 422 to rotate again, thereby driving the bending rod 423 and the stirring rod 424 below to rotate synchronously, stirring and mixing the samples sampled from multiple points, and completing the sample preparation.
