Description

Technical Field

[0001] This utility model relates to the technical field of mineral sampling equipment, specifically a sampler for distinguishing the composition of lead-zinc ore. Background Technology

[0002] In the mining and processing of mineral resources, lead-zinc ore, as an important mineral resource, requires accurate component analysis for subsequent processing technology selection and product quality control. The sampling process is particularly crucial for obtaining accurate component analysis results. Existing sampling equipment has many shortcomings in practical applications and urgently needs improvement and optimization. Taking utility model patent CN202222863201.7 as an example, this patent discloses a sampler for identifying the components of lead-zinc ore. It achieves the crushing and sampling function of lead-zinc ore through a combination of components such as a mounting frame, storage frame, motor support frame, fixing frame, conveying motor, transmission gear, conveying frame, spiral feed disc, rotating shaft, storage frame, crushing motor, crushing roller, and crushing frame. However, this equipment still has some problems in actual use.

[0003] First, its crushing process is relatively simple, relying solely on crushing rollers to crush lead-zinc ore. For lead-zinc ores with high hardness or complex compositions, the crushing effect is insufficient, potentially affecting the accuracy of subsequent component analysis. Second, the equipment is inconvenient in collecting and processing the crushed material. The crushed lead-zinc ore falls directly into the storage frame, lacking further grinding and screening processes, which cannot meet the particle size requirements for high-precision component analysis. Furthermore, the overall structure of the equipment is complex, with numerous operating steps requiring frequent manual intervention, reducing work efficiency and increasing the workload of operators.

[0013] (III) Beneficial Effects This invention provides a sampler for distinguishing the composition of lead-zinc ore, which has the following advantages: 1. This utility model effectively solves the problem of poor crushing effect in existing samplers by setting up a combination structure of crushing and grinding components. The two crushing rollers in the crushing component mesh and rotate under the drive of a first motor, which can initially crush the lead-zinc ore, reducing its particle size and providing a good foundation for the subsequent grinding process. Subsequently, the crushed lead-zinc ore enters the grinding component, where the grinding rollers, driven by a second motor, closely abut against the grinding plate and rotate relative to it, further grinding and refining the lead-zinc ore. This two-stage crushing and grinding structure design allows the lead-zinc ore to achieve a smaller and more uniform particle size, thereby improving the accuracy and reliability of subsequent component detection. Simultaneously, the multiple first perforations on the grinding plate and the multiple second perforations on the top plate allow the ground lead-zinc ore to be screened according to particle size. Lead-zinc ore particles smaller than the diameter of the first perforation holes can smoothly pass through the grinding plate into the collection box, while larger particles continue to be ground on the grinding plate, further ensuring the particle size uniformity of the sample and meeting the particle size requirements of high-precision component detection.

[0014] 2. This utility model, through optimized equipment structure, simplifies material collection and processing, solving the problem of inconvenient material collection and processing in existing samplers. The collection box inserted at the bottom of the grinding chamber facilitates the collection of lead-zinc ore samples after grinding and screening. Operators only need to pull the collection box out from the bottom of the grinding chamber to easily obtain the required sample, eliminating the need for cumbersome cleaning and transfer operations. Furthermore, the reciprocating lifting function of the top plate plays an important auxiliary role in the grinding process. When the grinding roller rotates to one side, the ejector pins on the top plate can insert into the holes in the grinding plate, ejecting larger lead-zinc ore particles stuck in the holes, preventing blockage and ensuring smooth grinding. Simultaneously, the lifting motion of the top plate also ensures a more uniform distribution of lead-zinc ore particles on the grinding plate, improving grinding efficiency and quality. This structural design not only simplifies the material collection and processing process but also improves the operational stability and reliability of the equipment, reduces equipment failures caused by material blockage, and lowers equipment maintenance costs and repair frequency.

[0020] Please see Figures 1 to 4 The present invention provides a technical solution: a sampler for distinguishing the composition of lead-zinc ore, comprising a grinding box 1, a crushing component, a grinding component, and a collection box 16.

[0021] A feed hopper is fixedly installed on the top wall of the grinding box 1 and the two are connected. The crushing component is installed on the feed hopper.

[0022] The grinding components include a second motor 6, a grinding plate 12, a second rotating shaft 8, and a grinding roller 10. The second motor 6 is fixedly installed on the outer side wall of the grinding box 1. The grinding plate 12 is generally arc-shaped and is fixedly installed on the inner side wall of the grinding box 1. The second rotating shaft 8 is rotatably installed on the grinding box 1. The grinding roller 10 is installed on the second rotating shaft 8. The second motor 6 is connected to the second rotating shaft 8 for transmission. The grinding roller 10 abuts against the upper surface of the grinding plate 12.

[0023] The grinding box 1 houses the crushing and grinding components, enabling the crushing, grinding, and screening of lead-zinc ore to ensure uniform sample particle size for subsequent component analysis. The crushing components perform preliminary crushing of the lead-zinc ore, reducing its particle size to prepare for subsequent grinding. The grinding components, through the close cooperation and relative rotation of the grinding rollers 10 and grinding plates 12, further grind and refine the crushed lead-zinc ore, making its particle size even smaller and more uniform, meeting the particle size requirements for high-precision component analysis. The grinding components are driven by the second motor 6 to rotate the second rotating shaft 8, causing the grinding rollers 10 to roll on the upper surface of the grinding plates 12, further refining the lead-zinc ore to achieve uniform particle size and meet the requirements for component analysis.

[0024] Specifically, the grinding component also includes two fixed plates 9. One end of the fixed plate 9 is fixedly connected to the outer wall of the second rotating shaft 8, and both ends of the grinding roller 10 are rotatably connected to the two fixed plates 9 respectively. A baffle 11 is fixedly installed on the fixed plate 9.

[0025] The fixed plate 9 connects the second rotating shaft 8 to the grinding roller 10, ensuring the stable rotation of the grinding roller 10. The baffle 11 is fixed on the fixed plate 9 and is used to spread the lead-zinc ore on the grinding plate 12, preventing it from falling and deforming the grinding roller 10, and ensuring the smooth progress of the grinding process.

[0026] Specifically, a collection box 16 is inserted into the lower part of the grinding box 1.

[0027] The collection box 16 is used to collect lead-zinc ore samples after grinding and screening. Operators can directly pull out the collection box 16 to conveniently obtain samples, simplifying the material collection process and improving sampling efficiency.

[0028] Specifically, a top plate 15 is longitudinally slidably installed on the inner side wall of the grinding box 1, and a second motor 6 is connected to the top plate 15 for transmission, and the second motor 6 drives the top plate 15 to reciprocate up and down.

[0029] More specifically, a plurality of ejector pins are fixedly connected to the upper surface of the top plate 15, and a plurality of first leakage holes are formed on the grinding plate 12, the first leakage holes corresponding vertically to the ejector pins. A plurality of second leakage holes are formed on the top plate 15, the diameter of the second leakage holes being larger than the diameter of the first leakage holes.

[0030] The second motor 6 starts, driving the top plate 15 up and down via a transmission mechanism. The ejector pins on the top plate 15 can insert into the holes of the grinding plate 12, ejecting larger lead-zinc ore particles stuck in the holes to prevent blockage. This also ensures a more uniform material distribution on the grinding plate 12, improving grinding efficiency and quality. When the top plate 15 rises and falls, the ejector pins can insert into the first drain hole to eject larger lead-zinc ore particles stuck in the hole, preventing blockage. The second drain hole on the top plate 15 has a larger diameter than the first drain hole, facilitating the passage of ground lead-zinc ore particles, achieving particle size screening. This ensures that particles smaller than the first drain hole diameter smoothly enter the collection box, while larger particles continue to be ground.

[0031] More specifically, the grinding box 1 has a sandwich layer on its side wall, and the grinding components also include a crankshaft 7 and a connecting rod 14. One end of the crankshaft 7 is coaxially and fixedly connected to the output shaft end of the second motor 6, and the other end of the crankshaft 7 is coaxially and fixedly connected to one end of the second rotating shaft 8.

[0032] More specifically, the upper end of the connecting rod 14 is rotatably connected to the crank portion of the crankshaft 7, and the lower end of the connecting rod 14 is rotatably mounted with a third rotating shaft 13, which is fixedly connected to the top plate 15.

[0033] The grinding chamber 1 has a crankshaft 7 and a connecting rod 14 installed in the side wall interlayer, forming the lifting transmission mechanism of the top plate 15. The second motor 6 starts, driving the crankshaft 7 to rotate. The crankshaft 7, through the connecting rod 14, converts the rotational motion into the reciprocating lifting motion of the top plate 15. When the grinding roller 10 rotates, the ejector pins on the top plate 15 can insert into the holes of the grinding plate 12, ejecting larger lead-zinc ore particles stuck in the holes, preventing blockage, and simultaneously making the material distribution on the grinding plate 12 more uniform, improving grinding efficiency and quality.

[0034] Specifically, the crushing component includes a first motor 2, two crushing rollers 4, and two first rotating shafts 3. The two crushing rollers 4 are respectively mounted on the two first rotating shafts 3, and the crushing rollers 4 are fixedly connected to the first rotating shafts 3. Both first rotating shafts 3 are rotatably mounted on the feed hopper. The first motor 2 is fixedly mounted on the top wall of the grinding box 1, and the first motor 2 is connected to the first rotating shafts 3 in a transmission connection. Gears 5 are fixedly mounted on the ends of both first rotating shafts 3, and the two gears 5 mesh with each other.

[0035] The crushing component consists of a first motor 2, two crushing rollers 4, and two first rotating shafts 3, and is used for the initial crushing of lead-zinc ore. The two crushing rollers 4 are respectively fixedly mounted on the two first rotating shafts 3. The first motor 2 drives the first rotating shafts 3 to rotate via a transmission connection, thereby driving the crushing rollers 4 to rotate. Gears 5 at the ends of the two first rotating shafts 3 mesh with each other, realizing the relative rotation of the two crushing rollers 4, compressing and crushing the lead-zinc ore to reduce its particle size, providing a foundation for subsequent grinding processes.

[0036] When in use, lead-zinc ore is fed into the feed hopper at the top of the grinding box 1, and the lead-zinc ore first enters the crushing part.

[0037] The first motor 2 starts, driving the two first rotating shafts 3 to rotate, which in turn drives the two crushing rollers 4 to rotate relative to each other, thus performing preliminary crushing of the lead-zinc ore and reducing its particle size.

[0038] Grinding preparation: The crushed lead-zinc ore falls onto the grinding plate 12, the second motor 6 starts, driving the crankshaft 7 and the second rotating shaft 8 to rotate.

[0039] Grinding process: The second rotating shaft 8 drives the grinding roller 10 and the baffle 11 to rotate through the fixed plate 9. The baffle 11 spreads the lead-zinc ore flat on the grinding plate 12 and prevents the lead-zinc ore from falling and deforming the grinding roller 10. The grinding roller 10 grinds and refines the lead-zinc ore on the grinding plate 12.

[0040] Particle size screening: Lead-zinc ore particles smaller than the diameter of the first hole on the grinding plate 12 fall into the collection box 16 through the hole, while larger particles continue to be ground on the grinding plate 12.

[0041] Anti-clogging mechanism: When the grinding roller 10 rotates 180 degrees to one side, the crankshaft 7 drives the top plate 15 to move upward through the connecting rod 14. The ejector pin on the top plate 15 inserts into the hole on the grinding plate 12, ejecting the larger lead-zinc ore particles stuck in the hole and preventing the hole from becoming blocked. Subsequently, the second motor 6 reverses, and the top plate 15 moves downward to reset.

[0042] Sample collection: After grinding is completed, the operator will pull out the collection box 16 from the bottom of the grinding box 1 to obtain the lead-zinc ore sample after grinding and screening, thus completing the sampling process.
