Description

Technical Field

[0001] This utility model relates to the field of gold mine geological sample classification technology, and in particular to a rapid gold mine geological sample classification device. Background Technology

[0002] The analysis of geological samples from gold deposits is crucial for gold deposit assessment, mining, and beneficiation decisions. Sample classification is fundamental to sample analysis, and its importance is self-evident. By classifying different types of samples, the occurrence state, grade variations, and geochemical anomalies of gold ore bodies can be more accurately reflected, providing representative samples for subsequent analytical testing. Vibrating screens and similar equipment are commonly used classification devices, separating samples according to particle size (e.g., fine, medium, coarse). This classification method is based on the differences in physical properties (e.g., density, compositional distribution) and subsequent processing requirements (e.g., pulverization requirements) of samples of different particle sizes, laying the foundation for subsequent analytical procedures.

[0003] Although equipment such as vibrating screens is widely used in the classification of geological samples in gold mines, existing classification devices still have some problems: if samples of different particle sizes are mixed, analytical errors may occur due to signal interference (such as light scattering and uneven elemental distribution), affecting the reliability and accuracy of the analytical results. Therefore, currently, samples of different particle sizes are generally processed separately, which greatly reduces the sample processing efficiency and makes it difficult to meet the needs of large-scale mechanized production.

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0024] like Figure 1As shown, this utility model includes a base 1, and a sieving mechanism 2 for vibrating and sieving samples is provided on the right side of the top of the base 1. The sieving mechanism 2 is slidably connected to the base 1. A dispensing mechanism 3 for dispensing samples of different particle sizes is provided on the front side of the base 1. The top of the dispensing mechanism 3 is connected to the bottom of the sieving mechanism 2.

[0025] like Figure 2 As shown, a U-shaped plate 11 is vertically arranged around the top right side of the base 1. The left side of the U-shaped plate 11 is open, and a drive motor 12 is installed on the front side wall of the U-shaped plate 11. A semi-circular fixing plate 13 is installed on the inner side of the U-shaped plate 11. The rotating shaft of the drive motor 12 passes through the fixing plate 13 and is connected to an eccentric disk 15, which is also located on the inner side of the U-shaped plate 11. A pull rod 14 is installed on the edge of the eccentric disk 15. One end of the pull rod 14 is rotatably connected to the eccentric disk 15, and the other end of the pull rod 14 is rotatably connected to the bottom of the screening mechanism 2.

[0026] Combination Figure 1 and Figure 3 As shown, the screening mechanism 2 includes a stepped screening frame 21. The front and rear sides of the screening frame 21 are slidably connected to the inner sides of the U-shaped plate 11, respectively. The screening frame 21 and the base 1 are inclined at a 15° angle, with the left side of the screening frame 21 lower than the right side. The screening frame 21 consists of three screening plates: a coarse particle screening plate 211 at the top, a medium particle screening plate 212 in the middle, and a bottom plate at the bottom. The end of the pull rod 14 is rotatably connected to the bottom of the bottom plate. A coarse particle feed pipe 22 is provided at the bottom left side of the coarse particle screening plate 211, which passes through the medium particle screening plate 212 and the bottom plate in sequence. A medium particle feed pipe 23 is provided at the bottom left side of the medium particle screening plate 212, which passes through the bottom plate. A fine particle feed pipe 24 is provided at the bottom left side of the bottom plate.

[0027] Combination Figure 1 and Figure 4 As shown, the dispensing mechanism 3 includes three dispensing cabinets 32 arranged side by side. Each dispensing cabinet 32 ​​has a receiving pipe 33 at its top for connection to a corresponding discharge pipe. Each dispensing cabinet 32 ​​has a funnel-shaped arc-shaped cavity 37 inside, and a discharge channel 313 at the bottom of each arc-shaped cavity 37. Each dispensing cabinet 32 ​​has an inverted U-shaped groove 31 at its bottom, and a receiving cup 314 is located within the inverted U-shaped groove 31, directly below the discharge channel 313. By providing receiving cups 314 at the bottom of each dispensing cabinet 32, the samples that have undergone further processing after classification can be recovered separately, facilitating subsequent sample testing or re-screening processes.

[0028] The three dispensing cabinets 32, from left to right, are, in order, a fine-particle sample dispensing cabinet 32, a medium-particle sample dispensing cabinet 32, and a coarse-particle sample dispensing cabinet 32. The receiving pipe 33 at the top of the fine-particle sample dispensing cabinet 32 ​​is connected to the lower end of the fine-particle discharge pipe 24; the receiving pipe 33 at the top of the medium-particle sample dispensing cabinet 32 ​​is connected to the lower end of the medium-particle discharge pipe 23; and the receiving pipe 33 at the top of the coarse-particle sample dispensing cabinet 32 ​​is connected to the lower end of the coarse-particle discharge pipe 22. The lower end of each discharge pipe 23 can extend into the upper opening of the corresponding receiving pipe 33.

[0029] The top of the medium-particle sample dispensing cabinet 32 ​​is equipped with a shearing motor 34, and the output end of the shearing motor 34 is equipped with a connecting shaft 310. The connecting shaft 310 is located inside the arc-shaped cavity 37, and the bottom end of the connecting shaft 310 is equipped with a shearing blade 39. The feeding channel 313 of the medium-particle sample dispensing cabinet 32 ​​is equipped with an electric push rod 38, and the top of the electric push rod 38 is equipped with a blocking block 312 that can move up and down to seal the bottom of the arc-shaped cavity 37.

[0030] The top of the coarse sample dispensing cabinet 32 ​​is equipped with an L-shaped support frame 36, on which a stamping rod 35 is mounted. The bottom of the stamping rod 35 extends into the interior of the arc-shaped cavity 37, and the bottom end of the stamping rod 35 is equipped with a stamping seat 311 for impact crushing of coarse particles. An electric push rod 38 is installed in the feeding channel 313 of the coarse sample dispensing cabinet 32. The top of the electric push rod 38 is equipped with a blocking block 312 that can move up and down to seal the bottom of the arc-shaped cavity 37.

[0031] By setting up a multi-stage particle size sieving mechanism 2, samples of different particle sizes can be sieved and fed into corresponding dispensing cabinets 32 through corresponding feed pipes. This achieves integrated processing of sieving and classifying samples of different particle sizes, saving time and effort. It eliminates the need for repeated individual processing based on sample particle size differences, thus improving sample processing efficiency. By setting corresponding sample crushing devices in the medium-particle sample dispensing cabinet 32 ​​and the coarse-particle sample dispensing cabinet 32, large-particle samples can be directly reprocessed after classification, enhancing the integrated functionality of the device and further improving sample processing efficiency.

[0032] The rapid classification device for gold ore geological samples described in this utility model is used as follows:

[0033] First, the sample is tilted downwards from the top right side of the sieving frame 21. The drive motor 12 is started, and the rotating shaft drives the eccentric disk 15 to rotate, which in turn drives the pull rod 14 to rotate. The pull rod 14 pulls the entire sieving frame 21 to slide left and right inside the U-shaped plate 11. Under the shaking of the sieving frame 21, the sample is sieved downwards through the sieving plates. Coarse samples remain on the coarse sieve plate 211, medium samples fall from the coarse sieve plate 211 onto the medium sieve plate 212, and fine samples are finally collected on the bottom plate. At the same time, under the action of gravity, the samples are uniformly concentrated to the left side of the sieving plates and finally fall into the corresponding dispensing cabinet 32 ​​from the corresponding feed pipe after sieving.

[0034] After passing through the arc-shaped cavity 37 of the fine sample dispensing cabinet 32, the fine sample falls directly from the feeding channel 313 into the receiving cup 314, after which the next step of the testing operation can be carried out.

[0035] Medium-sized and coarse-sized samples require further processing. By controlling the electric actuator 38, the block 312 is used to seal the feeding channels 313 of the medium-sized sample dispensing cabinet 32 ​​and the coarse-sized sample dispensing cabinet 32. In the medium-sized sample dispensing cabinet 32, the shearing motor 34 is activated, causing the connecting shaft 310 to rotate, which in turn drives the shearing blades 39 to rotate synchronously, shearing and grinding the medium-sized samples in the arc-shaped cavity 37, thereby reducing the particle size of the medium-sized samples. In the coarse-sized sample dispensing cabinet 32, the stamping rod 35 is activated, causing the stamping seat 311 to move up and down, impacting and crushing the coarse-sized samples in the arc-shaped cavity 37, thereby reducing the particle size of the coarse-sized samples. After shearing, grinding and impact crushing are completed, the electric actuator 38 is controlled again to move the block 312 upward, opening the lower feeding channel 313, allowing the reprocessed sample to fall into the receiving cup 314, and the sample in the receiving cup 314 is poured back into the screening rack 21 for screening.
