Description

Technical Field

[0001] The present invention relates to the technical field of mining engineering, and in particular to ore detection equipment, an automatic detection drill and a sample detection method. Background Art

[0002] In the open-pit mining industry, ore samples must be collected and tested regularly during the mining process to determine the ore grade—that is, the content of useful components or minerals. This helps understand the distribution and properties of the ore within the mine, thus guiding the mining process. Current methods for testing samples on-site in open-pit mines require manual collection of ore samples and then sending them to an off-site laboratory for testing. Due to the volatile environment of open-pit mines, samples are easily moved by wind, making manual sampling inaccurate and time-consuming.

[0028] In order to overcome the problems existing in the related technologies, such as Figure 1As shown, an exemplary embodiment of the present disclosure provides an ore testing device 100 for connection to a drill rig to obtain ore samples drilled by the drill rig for sample processing and testing. Ore testing device 100 can process and test samples while the drill rig is operating, effectively saving time and improving the efficiency of ore sample testing. Ore testing device 100 includes a sample preparation device 110, a packaging device 120, and a testing device.

[0029] The sample preparation device 110 is used to receive samples, grind and screen the samples to obtain target samples, and discharge them downward. During the operation of the drilling rig, the sample preparation device 110 can receive samples drilled by the drilling rig, such as ore particles and powder. After obtaining the sample, the sample preparation device 110 can automatically grind the obtained sample to obtain a sample with a smaller particle size, and then the sample preparation device 110 can screen the ground sample once or multiple times, so as to screen out the samples with smaller particles that meet the subsequent testing requirements from the ground sample as target samples, and transport the target samples to the packaging device 120. Among them, the sample preparation device 110 can automatically start according to the signal sent by the drilling rig when the drilling rig reaches a certain depth, so as to perform sampling, grinding and screening operations. In some embodiments, such as Figure 4 As shown, the ore testing equipment 100 may further include a support frame 190 for mounting and supporting the sample preparation device 110. The support frame 190 may include a flat plate portion and support legs at the bottom of the flat plate portion. The sample preparation device 110 may be mounted on the flat plate portion of the support frame 190 to ensure that the sample preparation device 110 is supported and stable by the support frame 190 during operation of the ore testing equipment 100. The packaging device 120 and the testing device may be disposed below the flat plate portion of the support frame 190, within the area enclosed by the support legs at the bottom of the support frame 190. The flat plate portion of the support frame 190 may have a through hole, allowing the bottom structure of the sample preparation device 110 to pass through the support frame 190, thereby allowing the target sample discharged by the sample preparation device 110 to pass through the through hole and be transported to the packaging device 120 located below the flat plate portion of the support frame 190. In some embodiments, the support frame 190 may be connected to a drill rig, so that the ore detection device 100 can be installed on the drill rig to obtain ore samples drilled by the drill rig during operation of the drill rig.

[0030] The packaging device 120, located below the sample preparation device 110, is used to receive and package the target samples produced by the sample preparation device 110. The packaging device 120 can be located downstream of the sample preparation device 110 to receive the target samples output by the sample preparation device 110. The packaging device 120 can bag the target samples and package the target samples in quantitative quantities. The packaging device 120 can package all target samples received within a time period into a single bag, allowing subsequent testing devices to determine the composition of the ore drilled during that time period and provide guidance for subsequent mining plans. The packaging device 120 can also bag the target samples received within a time period by weight or volume and compact the target samples to enable more accurate ore composition determination by subsequent testing devices, thereby improving the accuracy of ore grade analysis. Specifically, the packaging device 120 can bag each 20g of target sample, resulting in one or more bags of target samples, which can then be tested by a testing device, achieving higher detection accuracy. In addition, the packaging process can also code the packaged samples to mark the sample acquisition time, packaging time, and the volume or mass of the ore sample, etc., to facilitate subsequent sample collection and archiving. After drilling to a certain depth, the drill rig can send a signal to the ore testing equipment 100 to control the operation of the ore testing equipment 100 to process and analyze the sample. The packaging device 120 can mark the time when the signal sent by the drill rig is received on the packaged sample. The packaging device 120 can also code the packaged samples to mark the drill rig depth and location information corresponding to the time the sample was acquired, so as to facilitate the recording and integration of ore grade information at various locations and depths in the mine after the test is completed.

[0031] The detection device 130 is used to detect packaged target samples. The detection device 130 receives the packaged target samples provided by the packaging device 120 and performs separate testing on one or more bags of the sample, thereby obtaining quality information for each bag of target sample, including data such as ore content and composition. The detection device 130 can upload the monitored sample data in real time to a remote computer or cloud-based system for data recording and integration. The detection device 130 can be an automated fluorescence spectrometer capable of emitting a laser at the target sample, stimulating it to emit fluorescent photons. The automated fluorescence spectrometer receives the fluorescent photons, thereby obtaining a fluorescence spectrum of the target sample and determining the ore composition and content in the target sample based on the fluorescence spectrum. The detection device 130 can obtain sample information based on the coding applied to each bag of sample by the packaging device 120. This sample information can include one or more of the following: sample acquisition time, packaging time, drill depth and location information corresponding to the sample acquisition time, sample volume, and mass. The detection device 130 can also synchronously transmit the acquired sample information to a remote computer or cloud-based system. The detection device 130 detects target samples obtained at different times, locations, and depths of the drill rig, and uploads relevant information about the samples. In a remote computer, the ore grade at different locations in the mine and the ore grade at different depths at each location can be determined based on the sample information provided by the detection device 130. This allows for a summary analysis of the ore grade of the entire mine and a three-dimensional map of the mine grade distribution. Based on the sample information and the three-dimensional map of the mine grade distribution provided by the detection device 130, subsequent mining work can be adjusted to improve the efficiency of the mining project.

[0032] The ore testing equipment 100 provided by the embodiment of the present disclosure can be installed on a drilling rig to realize the automated processing and testing of ore samples. The ore testing equipment 100 can integrate the functions of grinding, screening, packaging and testing, and grind, screen, package and test ore samples while the drilling rig is working. The sample preparation device 110 can be automatically started according to the drilling rig signal to complete the sampling, grinding, screening and discharge of target samples; the packaging device 120 can quantitatively package and code the target samples; the testing device 130 automatically identifies the sample information and uploads the test results, with a high level of automation, which can effectively save manpower. The ore testing equipment 100 can automatically complete sample processing and testing while the drilling rig is working, thereby saving the time of manual sampling and the time of manual delivery of samples to the laboratory, significantly saving the time between sample acquisition and analysis, and improving the overall efficiency of ore testing. The support frame 190 ensures that the sample preparation device 110, packaging device 120, and detection device 130 remain stable during operation, preventing vibration or external forces from affecting the precision of sample processing and detection accuracy. The detection device 130 tests the target sample and uploads the data in real time, capable of obtaining ore grades at different times, locations, and drilling depths. This more accurate ore grade information enables a more precise assessment of mine resource quality, providing more objective and effective guidance for subsequent mining projects.

[0033] In some embodiments, as Figure 2 、 Figure 3 As shown, the sample preparation device 110 may include a grinding component 111 and a screening component 112 .

[0034] Grinding assembly 111 is configured to receive a sample. The grinding mechanism of grinding assembly 111 is configured to grind the sample, and the ground sample is discharged from the bottom of grinding assembly 111. Grinding assembly 111 may be provided with an inlet for receiving the sample, through which the ore sample to be processed can enter grinding assembly 111. Grinding assembly 111 may be provided with a grinding mechanism for grinding the sample. Processing the ore sample through the grinding mechanism can crush large sample particles, resulting in a smaller sample size that meets subsequent testing requirements, thereby improving sample quality. Grinding assembly 111 may have a discharge port at the bottom of the grinding assembly 111, through which the ground sample can fall from the bottom of the grinding assembly 111 to a subsequent processing assembly for subsequent screening. In some embodiments, the sidewalls of grinding assembly 111 may be provided with sieve holes or a screen installed, allowing the ground sample to pass through the sieve holes or screen, achieving a primary screening of the sample, and then discharge from the bottom of grinding assembly 111 to screening assembly 112. The screening component 112 receives the sample that has completed the first screening and can perform a second screening on the sample. The diameter of the sieve hole and the aperture of the sieve can be smaller than the size of the unground ore sample raw material, thereby ensuring that the unground or insufficiently ground sample cannot pass through the sieve hole and the sieve and enter the subsequent process, and can ensure that the grinding component 111 fully grinds the sample, thereby improving the quality of the ore sample. In some embodiments, the grinding component 111 may include: a grinding inner cylinder and a grinding outer cylinder. The grinding inner cylinder has an inlet on the top, a bottom plate for receiving the sample and a through grinding shaft hole in the center for rotating with the rotating shaft. The side wall of the grinding inner cylinder can be provided with a sieve; the grinding mechanism is provided in the grinding inner cylinder for grinding the sample. The grinding outer cylinder can be provided outside the grinding inner cylinder and coaxially with the grinding inner cylinder. The side wall of the grinding outer cylinder is spaced apart from the side wall of the grinding inner cylinder. The ground sample can pass through the sieve hole and be discharged from the bottom of the grinding outer cylinder. The grinding mechanism may include a rotating assembly and a grinding sheet. The rotating assembly may be connected to a rotating shaft so as to rotate along with the rotating shaft. The grinding sheet may be mounted on the rotating assembly to grind the sample following the rotation of the rotating assembly.

[0035] The screening component 112 is located below the grinding component 111 and is used to receive the ground sample. The rotating mechanism of the screening component 112 is used to push to screen the sample, and the screened sample is discharged from the bottom of the screening component 112. The screening component 112 can receive the sample falling from the bottom of the grinding component 111 and screen the sample. Figure 2As shown, the screening component 112 is located below the grinding component 111. A through hole for sample entry can be opened at the top of the screening component 112. The diameter of the through hole can be greater than or equal to the diameter of the discharge port at the bottom of the grinding component 111 to ensure that the screening component 112 can receive all samples falling from the bottom of the grinding component 111 to prevent sample leakage. The screening component 112 can be provided with a screen for screening samples with smaller particle sizes. The mesh size of the screen can be determined according to the detection requirements of subsequent equipment. Through the screen of the screening component 112 and the rotating mechanism provided inside the screen, the sample falling into the screening component 112 can be pushed to the screen by the rotating mechanism, so that the sample passes through the screen. Samples with smaller particle sizes can pass through the screen and are discharged outward from the bottom of the screening component 112, while samples with larger particle sizes cannot pass through the screen. Through the screening component 112, samples of different particle sizes after grinding can be screened and only samples with particle sizes that meet the requirements are discharged. A screening assembly 112 can be provided below the grinding assembly 111 so that the sample can be quickly screened through the screening assembly 112 after grinding, thereby quickly obtaining the target sample and discharging the target sample into the downstream equipment. Multiple screening assemblies 112 can be provided below the grinding assembly 111 so that the ground sample can be screened multiple times, further improving the screening accuracy and efficiency. The multiple screening assemblies 112 can be arranged sequentially from top to bottom so that the mesh size of the screening assembly 112 increases step by step from top to bottom, so that the sample is screened step by step, achieving multiple screening of the sample. Specifically, two screening assemblies can be provided below the grinding assembly 111, including a middle screening assembly and a terminal screening assembly, wherein the middle screening assembly can be used to receive the sample discharged by the grinding assembly 111, screen the sample once, and discharge the screened sample downwardly, and the terminal screening assembly can receive the sample discharged by the middle screening assembly, screen the sample twice, and discharge the screened target sample. The mesh size of the screen provided in the terminal screening assembly can be larger than that provided in the middle screening assembly. The larger the mesh size of the screen, the smaller the aperture of the screen. Screening the sample through a screen with a larger mesh size can yield a sample with a smaller particle size. The sample can first be coarsely screened through a screen with a smaller mesh size in the middle screening assembly, and then finely screened through a screen with a larger mesh size in the terminal screening assembly. This can prevent excessive accumulation of large-particle samples in the middle and terminal screening assemblies, which could result in smaller-particle samples being blocked by larger-particle samples and difficult to discharge, thereby ensuring a smooth screening process. In some embodiments, the screening assembly 112 can further include an inner screening cylinder and an outer screening cylinder. The bottom plate of the inner screening cylinder can be used to receive the ground sample and has a screening shaft hole extending through the center for rotational engagement with the rotating shaft. The sidewalls of the inner screening cylinder can be provided with a screen; a rotating mechanism can be located within the inner screening cylinder to propel the sample toward the screen.The outer screening cylinder can be disposed outside the inner screening cylinder and coaxially therewith, with the sidewalls of the outer screening cylinder spaced apart from the sidewalls of the inner screening cylinder. Samples screened by the screen mesh can be discharged from the bottom of the outer screening cylinder. A brush can be provided at the end of the rotating mechanism to clean the screen mesh of the screening assembly 112 during rotation of the rotating mechanism.

[0036] Through the sample preparation device 110 provided by the present disclosure, the grinding mechanism in the grinding assembly 111 can rotate at high speed to crush and grind the sample, which can achieve higher grinding efficiency, ensure that the particle size of the sample meets the subsequent detection requirements, improve the uniformity and applicability of the sample, and provide a reliable basis for subsequent detection and analysis. The ground sample can fall through the discharge port at the bottom of the grinding assembly 111 and enter the screening assembly 112. The rotating mechanism in the screening assembly 112 can push the sample to move radially toward the screen set on the circumferential side. Through the push of the rotating mechanism, samples with smaller particle sizes can pass through the screen smoothly and be discharged, while samples with larger particle sizes are retained in the terminal screening assembly, thereby achieving accurate screening of the sample particle size. The aperture of the screen can be adjusted according to actual needs to meet the processing requirements of different ore samples. In addition, multiple screening assemblies 112 can be set, and screens of different mesh sizes can be installed on each screening assembly 112, which can achieve multiple screening of the sample and graded screening from coarse to fine, further improving screening accuracy and efficiency. By gradually increasing the mesh size of the screen, it is also possible to effectively prevent large particles from getting stuck in the screen, causing the screening component 112 to jam, and ensure that the screening process proceeds smoothly. At the same time, setting up multiple screening components 112 can reduce the workload of a single screening component 112, extend the service life of the equipment, and make the screening efficiency higher, and the particle size control of the target sample more accurate. This process greatly improves the accuracy and efficiency of material processing. The sample preparation device 110 provided by the present disclosure integrates the functions of grinding and screening, effectively improves the efficiency of ore sample preparation, can realize automated and continuous operation, effectively reduce manual intervention, improve work efficiency, and reduce energy consumption.

[0037] In some embodiments, as Figure 2 、 Figure 3 As shown, the sample preparation device 110 may further include: a rotating shaft 1, which is provided through the grinding assembly 111 and the screening assembly 112 and is fixedly connected to the grinding mechanism of the grinding assembly and the rotating mechanism of the screening assembly respectively, so as to drive the grinding mechanism and the rotating mechanism to rotate by rotating. Figure 2 、 Figure 3As shown, the grinding assembly 111 and the screening assembly 112 can each be provided with an axial hole for the rotating shaft to pass through, so that the rotating shaft can be set through the grinding assembly 111 and the screening assembly 112. The rotating shaft can be connected to the grinding mechanism, so that the grinding mechanism can be driven to move by the rotation of the rotating shaft, so that the grinding mechanism can grind the sample. The connection between the rotating shaft and the grinding mechanism can be detachable, so that the grinding mechanism can be easily replaced and repaired. Figure 3 As shown, the rotating shaft can be connected to the rotating mechanism, so that the rotation of the rotating shaft can drive the movement of the rotating mechanism, allowing the rotating mechanism to rotate and push the sample within the screening assembly 112, so that the sample passes through the screen provided on the side of the screening assembly 112 for screening. The rotating shaft can be provided with a first motor 117 for driving the rotating shaft. The first motor can be arranged at the top of the rotating shaft, driving the rotating shaft to maintain the rotating shaft in a rotating state, thereby driving the movement of the rotating mechanism and the grinding mechanism to achieve the grinding and screening functions.

[0038] In some embodiments, as Figure 2 、 Figure 3 As shown, the sample preparation device 110 may further include: a device housing 113 and a drying component 114 .

[0039] The device housing 113 is provided on the outer peripheral side of the grinding component 111 and the screening component 112. The device housing 113 can be used to protect the grinding component 111 and the screening component 112 inside it. Since the ore detection equipment 100 can be installed on a drilling rig working at a mine site, it can process ore samples while drilling the mine, has good real-time performance, and can instantly process and detect the quality of the ore excavated in the mine while drilling the mine, which can effectively improve the work efficiency of the mining site. Therefore, the ore detection equipment 100 is located in an open-pit mine, and its environment is relatively complex. There may be some external impurities blown into the ore detection equipment 100 by the wind, and enter the sample preparation device 110, resulting in a large number of impurities in the target sample obtained by the sample preparation device 110. In order to ensure the efficiency and effect of sample processing, while protecting the various functional components inside the sample preparation device 110, and ensuring high safety in harsh environments, a device housing 113 can be provided on the outer peripheral side of the grinding component 111 and the screening component 112, such as Figure 3 As shown, the device housing 113 surrounds these functional components to provide protection.

[0040] The drying component 114 is fixedly arranged inside the device housing 113, located on the outer periphery of the grinding component 111 and the outer periphery of the screening component 112, and is used to dry the sample. The drying component 114 can be a columnar infrared drying device, such as an infrared heating lamp. Figure 2 、 Figure 3As shown, the drying component 114 can be fixed on the inner side of the device housing 113 and arranged toward the grinding component 111 and the screening component 112. It can dry the sample during the grinding, screening and falling process of the sample and effectively remove moisture from the sample.

[0041] According to the sample preparation device 110 provided in this embodiment, by providing a device housing 113, dust, debris and other impurities in the external environment can be effectively blocked from entering the interior of the sample preparation device 110, thereby preventing impurities from contaminating the sample during the grinding and screening process, ensuring the purity and quality of the prepared target sample, and thus ensuring the accuracy of subsequent testing or other processing of the target sample. By means of the drying component 114, moisture in the sample can be effectively removed, preventing the sample from adhering to, agglomerating, and other problems during the grinding or screening process due to excessive water content, thereby improving the efficiency and accuracy of grinding and screening. Continuously drying the sample during the grinding, screening, and falling process can ensure that the sample is evenly heated throughout the entire processing process, further improving the sample preparation quality while achieving higher efficiency. The device housing 113 can prevent hard particles, rainwater, wind and sand in the external environment from wearing and corroding the internal structure of the sample preparation device 110, thereby extending the service life of the sample preparation device 110, reducing the incidence of failures, and improving its reliability. In addition, the device housing 113 can also reduce the possibility of sample splashing or dust spreading to the external environment during the grinding and screening process, thereby improving the safety of the sample preparation device 110 operation.

[0042] In some embodiments, as Figure 2 、 Figure 3 As shown, the sample preparation device 110 may further include a material receiving mechanism 115, disposed below the screening assembly 112, for receiving the target sample and waste material discharged from the bottom of the screening assembly 112. After sample preparation is completed, the sample preparation device 110 can discharge the waste material inside. A grinding waste discharge port can be provided on the side wall of the grinding assembly 111. The grinding waste discharge port can remain closed during the sample preparation process. During the waste discharge process, the grinding waste discharge port can be opened, allowing the waste material in the grinding assembly 111 to enter the material receiving mechanism 115 directly through the grinding waste discharge port, or enter the screening assembly 112 and be discharged together with the waste material in the screening assembly 112. The screening assembly 112 may also be provided with a screening waste discharge port. The screening waste discharge port can remain closed during the sample preparation process. During the waste discharge process, the screening waste discharge port can be opened, allowing the waste material in the screening assembly 112 to enter the material receiving mechanism 115 through the screening waste discharge port and be discharged out of the sample preparation device 110 through the material receiving mechanism 115. The top of the material receiving mechanism 115 can be connected to the bottom of the screening assembly 112. The material receiving mechanism 115 can include: a sample tube 1151, a waste tube 1152 and a rotating cylinder.

[0043] The sample tube 1151 is used to receive the target sample that has been screened and discharged from the bottom of the screening component 112. Figure 3 As shown, sample tube 1151 can be disposed below screening assembly 112, and the top of sample tube 1151 can be fixedly connected to the bottom of screening assembly 112, so that the target sample can directly enter sample tube 1151 after being discharged from the bottom of screening assembly 112, and enter subsequent processing equipment or collection equipment along sample tube 1151. The bottom of sample tube 1151 can be connected to packaging device 120, so that the target sample can be transported from sample tube 1151 to packaging device 120 for packaging.

[0044] The waste pipe 1152 is used to receive the waste discharged from the bottom of the screening assembly 112. Figure 3 As shown, the waste pipe 1152 can be disposed below the screening assembly 112. The waste pipe 1152 and the sample tube 1151 can be disposed in parallel, so that when the sample preparation device 110 is in the waste discharge state, waste material discharged from the bottom of the screening assembly 112 can enter the waste pipe 1152 and be discharged outside the sample preparation device 110 along the waste pipe 1152.

[0045] The rotary cylinder is used to drive a baffle to rotate to block the sample tube 1151 or the waste tube 1152, allowing the target sample to fall into the sample tube 1151 or the waste tube 1152. The output shaft of the rotary cylinder can extend into the sample tube 1151 and the waste tube 1152, and a baffle can be provided on the output shaft. The baffle can match the inner diameter of the sample tube 1151 and the waste tube 1152 to facilitate blocking the sample tube 1151 or the waste tube 1152. When the sample preparation device 110 is in the sample preparation state, the rotation of the rotary cylinder output shaft can drive the baffle to rotate toward the waste tube 1152, thereby blocking the waste tube 1152 and allowing the target sample to be discharged from the bottom of the screening assembly 112 into the sample tube 1151. When the sample preparation device 110 is in the waste discharge state, the output shaft of the rotary cylinder can be rotated to drive the baffle to rotate toward the sample tube 1151, thereby blocking the sample tube 1151 and allowing the waste to be discharged from the bottom of the screening component 112 to the waste pipe 1152. Figure 3As shown, the sample tube 1151 and the waste tube 1152 can also form a Y-shaped three-branch pipeline, which is divided into the sample tube 1151 and the waste tube 1152 at the end away from the screening assembly 112. A baffle can be set at the branch of the three-branch pipeline. When the sample preparation device 110 is in the sample preparation state, the baffle can be driven by the rotating cylinder to rotate toward the waste tube 1152, thereby blocking the waste tube 1152, allowing the target sample that has completed grinding and screening to fall along the three-branch pipeline into the sample tube 1151 and enter the packaging device 120 along the sample tube 1151. When the sample preparation device 110 is in the waste discharge state, the baffle can be driven by the rotating cylinder to rotate toward the sample tube 1151, thereby blocking the sample tube 1151, allowing waste to fall along the three-branch pipeline into the waste tube 1152 and be discharged outside the sample preparation device 110 along the waste tube 1152.

[0046] According to the sample preparation device 110 provided in this embodiment, a rotary cylinder in the material receiving mechanism 115 drives a baffle to rotate, effectively blocking the sample tube 1151 or the waste tube 1152. This ensures accurate diversion of the target sample and waste, preventing mixing that could compromise sample quality, thereby improving the accuracy and purity of the sample preparation process. Furthermore, the automated operation of the rotary cylinder reduces manual intervention, effectively improving the automation level and work efficiency of the device.

[0047] In some embodiments, the sample preparation device 110 may further include a plurality of discharge valves, which are arranged on the outside of the grinding component 111 and cooperate with the grinding waste outlet to close or open the grinding waste outlet. The discharge valve may also be arranged on the outside of the screening component and cooperate with the screening waste outlet to close or open the screening waste outlet. The discharge valve may cooperate with the grinding waste outlet so that the discharge valve remains closed during the sample preparation process, the grinding waste outlet hole is closed, the sample is blocked, and the sample cannot be discharged from the grinding waste outlet. When the equipment completes ore sampling and enters the waste discharge state, the discharge valve can be opened, thereby opening the grinding waste outlet, and the waste in the grinding component 111 can be discharged through the grinding waste outlet. The discharge valve may also cooperate with the screening waste outlet so that the discharge valve remains closed during the sample preparation process, the screening waste outlet hole is closed, the sample is blocked, and the sample cannot be discharged from the screening waste outlet. After the equipment completes ore sampling and enters the waste discharge state, the discharge valve can be opened, thereby opening the screening waste discharge port, and the waste in the screening component 112 can be discharged through the screening waste discharge port.

[0048] In some embodiments, as Figure 2As shown, the sample preparation device 110 may further include a suction mechanism 116 for sucking in samples from the outside and delivering them to the grinding assembly 111. The ore testing equipment 100 also includes an air compressor 140 for driving the suction mechanism 116. The suction mechanism 116 may be a vacuum suction mechanism 116, which can suck ore particles drilled by the drill rig from the outside into the sample preparation device 110, allowing the ore particles to enter the suction mechanism 116 as samples. The suction mechanism 116 may be partially funnel-shaped, allowing the suction mechanism 116 to store a certain volume of sample. The bottom of the suction mechanism 116 may be connected to the top of the grinding assembly 111, and the bottom of the suction mechanism 116 may be connected to an inlet provided at the top of the grinding assembly 111. The sample is then fed into the grinding assembly 111 through the inlet via the suction mechanism 116. The suction mechanism 116 may be provided with a valve. While the suction mechanism 116 is drawing in the sample, the valve may remain closed, allowing the drawn-in sample to be stored in the suction mechanism 116. A volume or weight threshold may be preset for the suction mechanism 116. When the volume or weight of the sample in the suction mechanism 116 reaches the threshold, the suction mechanism 116 stops drawing in the sample, and the valve opens, allowing the sample to fall from the suction mechanism 116 into the grinding assembly 111. The ore testing equipment 100 may include an air compressor 140. The air compressor 140 may be located on one side of the sample preparation device 110 and connected to the suction mechanism 116 of the sample preparation device 110, thereby driving the suction mechanism 116. The air compressor 140 may be located on the support frame 190, mounted on the flat plate portion of the support frame 190, and positioned near the sample preparation device 110. The air compressor 140 is supported by the flat plate portion of the support frame 190. The air compressor 140 can provide compressed air to the suction mechanism 116 to drive the suction mechanism 116 to absorb the sample. The suction mechanism 116 can be a vacuum suction device, and the vacuum suction device can be provided with a vacuum generator. The air compressor 140 can be connected to the vacuum generator to supply air to the vacuum generator. The air compressor 140 can deliver compressed gas to the vacuum generator. The vacuum generator can use the compressed air provided by the air compressor 140 to increase the air flow rate through the injection principle, thereby forming a local negative pressure area. The negative pressure area of the vacuum generator is connected to the suction end of the vacuum suction device, so that a vacuum environment can be formed inside the vacuum suction device through the action of negative pressure. Since the negative pressure inside the vacuum suction device is lower than the external atmospheric pressure, suction is formed. The external ore sample can be sucked into the vacuum suction device through the suction port of the vacuum suction device to achieve sample acquisition. The air compressor 140 can be turned on according to the depth of the drill. When the drill reaches a preset depth, a signal can be sent to the ore detection equipment 100, thereby starting the air compressor 140 of the ore detection equipment 100 and driving the suction mechanism 116 to suck in the ore sample drilled by the drill for processing and analysis.When the volume or weight of the sample in the suction mechanism 116 reaches a threshold, the air compressor 140 may be stopped to stop the suction mechanism 116 from sucking in the sample.

[0049] Through this embodiment, the suction mechanism 116 can be driven by the air compressor 140 to realize the process of automatically sucking in samples from the outside and transporting them to the grinding component 111, eliminating the step of manual loading, effectively improving the automation level of the equipment, reducing manual intervention, and improving work efficiency. The suction mechanism 116 can continuously suck in samples, and can accurately control the amount of samples entering the grinding component 111, ensuring that the samples entering the grinding component 111 are stable and uniform, and can improve the sample processing quality and sample preparation accuracy. The air compressor 140 and the sample preparation device 110 are both installed on the support frame 190. The installation structure is compact and space-saving, and the stability of the air compressor 140 and the suction device can be maintained through the support frame 190, avoiding vibration or external force during operation that affects the suction performance, while improving the overall durability of the equipment.

[0050] In some embodiments, as Figure 2 、 Figure 3 As shown, the sample preparation device 110 may further include: a first motor 117, located at the top of the sample preparation device 110, for providing power to drive the grinding assembly 111 and the screening assembly 112 to grind and screen the sample; a second motor 118, located at the bottom of the sample preparation device 110, for providing power to drive the grinding assembly 111 and the screening assembly 112 to discharge waste. The ore testing equipment 100 includes a generator 150 for providing power to the first motor 117 and the second motor 118. The first motor 117 can be the power supply element for the grinding assembly 111 and the screening assembly 112. The power provided by the first motor 117 can drive the grinding mechanism of the grinding assembly 111 to rotate, thereby grinding the sample to obtain a sample with smaller particles. The power provided by the first motor 117 can also drive the rotating mechanism of the screening assembly 112 to rotate, thereby screening the sample to obtain a target sample. The sample preparation device 110 may be provided with a rotating shaft, which may be connected to the grinding mechanism and the rotating mechanism respectively, and is used to rotate to drive the grinding mechanism and the rotating mechanism to work. The first motor 117 may be connected to the rotating shaft, and is used to supply power to the rotating shaft to drive the rotating shaft to rotate, thereby driving the grinding mechanism to rotate to grind the sample, and driving the rotating mechanism to rotate to push the sample to the sieve and sieve the sample. Figure 3As shown, the first motor 117 can be disposed at the top of the rotating shaft to drive the rotating shaft so that the rotating shaft remains in a rotating state. A second motor 118 can be disposed at the bottom of the sample preparation device 110. The second motor 118 can drive the grinding assembly 111 and the screening assembly 112, thereby enabling the grinding assembly 111 and the screening assembly 112 to discharge waste. The side wall of the grinding assembly 111 can be provided with a grinding waste discharge port. During the waste discharge process, the grinding waste discharge port can be opened so that the waste in the grinding assembly 111 can be discharged from the grinding waste discharge port to the outside of the sample preparation device 110, or enter the screening assembly 112 and be discharged from the sample preparation device 110 together with the waste in the screening assembly 112. The screening assembly 112 can also be provided with a screening waste discharge port. During the waste discharge process, the screening waste discharge port can be opened so that the waste in the screening assembly 112 can be discharged from the screening waste discharge port to the outside of the sample preparation device 110. The second motor 118 can drive the rotation of the grinding assembly 111 and the screening assembly 112 during the waste discharge process, so that the waste can be discharged from the grinding waste outlet to the outside of the sample preparation device 110. When the second motor 118 rotates for a certain period of time and reaches a preset time threshold, the waste discharge can be completed and the second motor 118 stops rotating. The ore testing equipment 100 may include: a generator 150. Figure 5 As shown, the generator 150 can be disposed to the side of the sample preparation device 110 and electrically connected to the first motor 117 and the second motor 118 of the sample preparation device 110, thereby supplying power to the first motor 117 and the second motor 118. The generator 150 can be disposed on the support frame 190, mounted on the flat portion of the support frame 190, and positioned near the sample preparation device 110, with the generator 150 supported by the flat portion of the support frame 190. When the drill reaches a certain depth, the sample preparation device 110 needs to be activated to draw in a sample and grind and sieve the sample. At this time, the generator 150 can power the first motor 117, driving the grinding assembly 111 to grind the sample and the sieving assembly 112 to sieve the sample. After the sample preparation device 110 completes grinding and screening of the sample, the waste material in the sample preparation device 110 needs to be discharged. The second motor 118 can be powered by the generator 150 to drive the grinding component 111 and the screening component 112, so that the waste material is discharged from the grinding waste outlet and the screening waste outlet to the outside of the sample preparation device 110.

[0051] Through the ore detection equipment 100 provided in this embodiment, the generator 150 can be used to power the first motor 117, drive the grinding assembly 111 and the screening assembly 112 to operate synchronously, realize continuous grinding and screening of the sample, and effectively improve the sample processing efficiency. By powering the second motor 118 through the generator 150, the grinding assembly 111 and the screening assembly 112 can be driven to operate synchronously, and the waste material can be automatically discharged out of the sample preparation device 110, with a high level of automation, which can reduce the manpower and time consumed in manual cleaning and waste discharge, can reduce manual intervention, and improve the efficiency of waste discharge. According to the requirements of different working states of the sample preparation device 110, the generator 150 can be used to power the first motor 117 and the second motor 118 respectively, so that the sample processing and waste discharge processes can be carried out independently, avoiding the mixing of samples and waste materials, and at the same time avoiding the waste residue affecting the processing quality of the next batch of samples, thereby maintaining the purity of the target sample.

[0052] In some embodiments, the sample preparation device 110 may further include a cleaning device, wherein the cleaning device may include a blower mounted on the device housing, capable of blowing air into the various devices within the device housing after the sample preparation device 110 has completed waste discharge, thereby clearing away waste dust and water vapor. The cleaning device may further include a vibrator mounted on the outer periphery of the screening assembly 112 and the grinding assembly 111. The vibrator may drive the grinding assembly 111 and the screening assembly 112 through its own vibration after the sample preparation device 110 has completed waste discharge, so that the sample, etc., trapped in the grinding assembly 111, the screening assembly 112, and the small particles of impurities in the screen can fall off with the vibration, thereby achieving cleaning of the sample preparation device 110.

[0053] In some embodiments, as Figure 4 、 Figure 5As shown, the ore testing equipment 100 may further include: a conveying device 160, disposed below the packaging device 120, for receiving packaged target samples and transporting them downstream. The testing device 130 is disposed to the side of the conveying device 160; and a collection device 170, disposed downstream of the conveying device 160, for collecting tested target samples. The conveying device 160 may be disposed below the packaging device 120, within the area enclosed by the support legs at the bottom of the support frame 190. The conveying device 160 may receive target samples discharged from the packaging device 120 and transport the samples to the testing device 130, which then processes one or more bags of packaged target samples on the conveying device 160. The ore testing equipment 100 may include a collection device 170, which may be located at the end of the conveying device 160 away from the packaging device 120. This allows samples to pass through the conveying device 160 and, from below the packaging device 120, travel along the conveying device 160 to the vicinity of the testing device 130. The testing device 130 then tests the target sample and obtains ore grade information. Finally, the target sample travels along the conveying device 160 to the collection device 170, which receives the tested target sample delivered by the conveying device 160 and stores it in the collection device 170. The collection device 170 may be located on the side of the ore testing equipment 100 away from the drilling rig, facilitating manual removal of target samples stored in the collection device 170 for organization and archiving. The conveying device 160 may be a conveyor belt, one end of which is located below the packaging device 120, allowing the packaged target sample to fall onto the conveyor belt and move along with it. The other end of the conveyor belt can be connected to the collection device 170, so that the target sample can eventually fall into the collection device 170. The detection device 130 can be set on the side of the conveyor belt, located in the middle of the conveyor belt, so as to detect the target sample transported by the conveyor belt and obtain ore grade information.

[0054] The ore testing equipment 100 provided in this embodiment can be connected in series through the conveying device 160, the packaging device 120, the detection device 130, and the collection device 170 to achieve automatic transmission of target samples, avoid manual handling of samples, save time, and effectively improve work efficiency. The collection device 170 can store the target samples that have completed the test in an orderly manner, facilitate subsequent manual sampling, sorting, and archiving, and improve management efficiency. In addition, the conveying device 160 can continuously transport the target samples, and the detection device 130 can synchronously obtain sample grade information in real time, avoiding data loss or sample omission, thereby ensuring the integrity of the test data.

[0055] In some embodiments, as Figure 4 、 Figure 5As shown, the ore testing equipment 100 may further include a shock absorbing mechanism 180 disposed at the bottom of the ore testing equipment 100 and / or on a side thereof near the drilling rig. The shock absorbing mechanism 180 may be disposed at the bottom of the ore testing equipment 100. A top plate may be provided on top of the shock absorbing mechanism 180 for connecting to the bottom support legs of the support frame 190, thereby supporting and damping the support frame 190 and structures mounted thereon, such as the sample preparation device 110 and the air compressor 140. The upper surface of the top plate may be used to mount the conveying device 160 and the testing device 130, and the shock absorbing mechanism 180 can provide support and dampen the vibrations of various components mounted thereon. The shock absorbing mechanism 180 can also be provided on the side close to the drill rig, so that the shock absorbing mechanism 180 can be provided on the side of the ore detection equipment 100 for connection with the drill rig, thereby more directly cushioning the ore detection equipment 100 through the shock absorbing mechanism 180, and reducing the vibration of the ore detection equipment 100 driven by the vibration of the drill rig. The shock absorbing mechanism 180 can include a damping spring shock absorber, and there can be one damping spring shock absorber, which is provided in the center of the bottom of the ore detection equipment 100, or in the center of the side close to the drill rig, so as to evenly disperse the force generated by the vibration of the drill rig, and avoid the vibration being directly transmitted to the sample preparation device 110, the packaging device 120 and the detection device 130 inside the equipment, thereby ensuring the normal operation and detection accuracy of the key components inside the equipment. There can be multiple damping spring shock absorbers, which can be evenly provided at the bottom of the ore detection equipment 100, or evenly provided on the side close to the drill rig. As Figure 5 As shown, four damping spring shock absorbers can be installed at the four corners of the ore testing equipment 100, making the shock absorbing mechanism 180 more stable in supporting other equipment in the ore testing equipment 100. The installation of the shock absorbing mechanism 180 can reduce equipment shaking caused by drilling rig vibration, effectively protecting the internal components and equipment of the ore testing equipment 100, reducing equipment losses caused by vibration, and extending the equipment's service life. Furthermore, the uniform placement of multiple damping spring shock absorbers can more evenly distribute the impact of vibration, preventing localized stress concentration from damaging the equipment base or frame.

[0056] In some embodiments, the ore testing equipment 100 may further include an external frame, positioned outside the sample preparation device 110, the packaging device 120, and the detection device 130. The external frame can be used to house and protect the sample preparation device 110, the packaging device 120, the detection device 130, and other structural components installed therein. Since the ore testing equipment 100 can be installed on a drilling rig, it needs to operate in a mine for a long period of time and must cope with the complex mining environment. The external frame, positioned outside the sample preparation device 110, the packaging device 120, and the detection device 130, can block external dust, debris, and other impurities from entering the equipment, thereby keeping the interior of the ore testing equipment 100 clean and preventing wear and corrosion of the internal structure caused by hard particles, rain, wind, and sand in the external environment. This extends the service life of the equipment, reduces the incidence of failures, and improves its reliability. A through hole for a waste pipe can be provided at the bottom or side of the external frame to facilitate the sample preparation device 110 to discharge waste materials out of the ore testing equipment 100 during the waste discharge process. A through hole for the suction mechanism 116 to pass through can also be provided on the top of the external frame, so that the suction mechanism 116 can pass through the external frame and suck in samples from the outside. In some embodiments, the external frame can be connected to the drilling rig, so that the ore detection equipment 100 can be installed on the drilling rig. The external frame provided by this embodiment can isolate the intrusion of external dust, debris and other impurities, and ensure the cleanliness and normal operation of key components such as the sample preparation device 110, the packaging device 120 and the detection device 130. In addition, the external frame can also enhance the structural strength of the equipment, provide a stable installation foundation for internal components such as the sample preparation device 110, the packaging device 120 and the detection device 130, reduce the interference of factors such as vibration and impact on the precision components inside the equipment, and improve the operation stability and reliability of the equipment in the harsh environment of the mine.

[0057] Based on the same inventive concept, the present disclosure also provides an automatic detection drilling rig, such as Figure 6 As shown, it may include: a drilling rig, and the ore detection device 100 as any of the above embodiments.

[0058] The drill rig includes a drill bit 211 for drilling holes to obtain samples, and a mobile carrier 212 for loading the drill rig. The drill rig can drill holes in the mine through the drill bit 211, thereby obtaining samples through the ore detection equipment 100 during the drilling process. The drill rig can be equipped with a depth detection component on the drill bit 211 for detecting the depth of the drill hole, so that the depth of the drill hole can be determined. When the drill bit 211 reaches the preset ore detection depth, the drill rig can send a signal to the ore detection equipment 100, thereby starting the ore detection equipment 100 to grind and analyze the samples drilled by the drill rig. The mobile carrier 212 can be used to load the drill rig. Since the drill rig needs to drill holes in various places on the mine, the ore detection equipment 100 can determine the mineral distribution and mineral content in various places on the mine. The drilling rig can move the mobile carrier 212 of the drilling rig according to the instructions of the layout diagram according to the preset drilling layout diagram, move the drilling rig to a designated position in the mine, and start the drill bit 211 to drill holes in the mine.

[0059] The ore detection equipment 100 is installed on the mobile carrier 212 of the drilling rig. The ore detection equipment 100 can be located at the rear of the automatic detection drilling rig and fixed on the mobile carrier 212. The ore detection equipment 100 can be fixedly installed on the mobile carrier 212, so that it moves with the mobile carrier 212 and works in the mine, so that it can process and detect the samples drilled by the drilling rig in real time, with better real-time performance. The ore detection equipment can be installed on the side of the mobile carrier 212 away from the drill bit 211, so that it can effectively avoid the vibration generated by the drill bit 211 when drilling the hole from interfering with the ore detection equipment 100, thereby improving the stability of the detection equipment operation and the accuracy of sample processing. In addition, it can also reduce the damage to the internal components of the ore detection equipment 100 caused by the impact generated by the drill bit 211 when drilling, thereby extending the service life of the detection equipment and improving the reliability and work efficiency of the overall operation of the automatic detection drilling rig.

[0060] The automatic detection drill provided by this embodiment can integrate the operations of drilling, sample collection, processing, and testing, integrating multiple functions. The ore testing equipment 100 can process and analyze samples obtained by the drill in real time, with better real-time performance. This allows for more rapid and accurate guidance for subsequent mining operations based on the analysis results obtained by the ore testing equipment 100, thereby improving the efficiency and accuracy of sample processing and the efficiency of subsequent mining operations. The automatic detection drill can achieve stable operation in harsh mining environments, reducing manual intervention and effectively avoiding errors in ore processing and testing caused by operational errors, thereby improving the safety, accuracy, and automation level of the automatic detection drill.

[0061] Based on the same inventive concept, Figure 7The present disclosure also provides a sample detection method, which can be used in the ore detection device 100 of any of the above embodiments, and can include: steps S310 to S340

[0062] In step S310, in response to the drill bit 211 of the drill rig reaching a preset depth, a sample is obtained through the sampling device 110. The drill rig's mobile carrier 212 can be automatically operated according to a preset drilling layout, causing the drill rig to move to a designated location in the mine and start drilling the mine with the drill bit 211. During the drilling process, the ore testing device 100 can remain in a stopped state. When the drill bit 211 of the drill rig reaches the preset depth, the drill rig can transmit a signal to the ore testing device 100, which can receive the signal and start, thereby activating the sampling device 110. The suction mechanism 116 of the sampling device 110 can be activated to draw the ore sample obtained by the drilling into the sampling device 110. The sample obtained by the sampling device 110 can be small ore particles and ore powder ejected during the drilling process. The sample obtained by drilling can be sucked by the suction mechanism 116 and sent into the grinding assembly 111 of the sample preparation device 110 .

[0063] Step S320, grind and screen the sample through the sample preparation device 110, and discharge the target sample. The sample preparation device 110 can obtain the sample drilled by the drill rig, and grind the sample through the grinding component 111 of the sample preparation device 110, so as to obtain a sample with a smaller particle size, so as to facilitate subsequent testing. The ground sample with a smaller particle size is then discharged into the screening component, and the sample is screened by the screening component. The screening component can be provided with a screen, and the aperture of the screen can be small, so that the sample with a particle size that meets the subsequent testing requirements is discharged as the target sample, while the sample with a larger particle size that does not meet the testing requirements can be retained in the screening component, and after the sample processing and screening are completed, it is discharged to the outside of the ore testing equipment 100 in a waste discharge state.

[0064] In step S330, the target sample is received and packaged by the packaging device 120, and the packaged target sample is discharged. The packaging device 120 can be located below the sample preparation device 110 so as to receive the target sample discharged by the sample preparation device 110. The packaging device 120 can be used to quantitatively package the target sample and compact the target sample to facilitate subsequent testing of the target sample. The packaging device 120 can also code the packaged sample and mark the drill depth and position information corresponding to the time when the sample was obtained, so as to facilitate the recording and integration of the ore grade information at various locations and depths in the mine after the subsequent testing is completed. After the packaging device 120 completes the packaging of the target sample, it can discharge the target sample so that the target sample can enter the subsequent testing process.

[0065] In step S340, the target sample is detected by the detection device 130 to determine the taste information of the target sample. The detection device can detect the target sample packaged by the packaging device 120. The detection device 130 can be an automatic fluorescence spectrum analysis device, which can emit a laser to the target sample, excite the target sample to emit fluorescent photons, and receive the fluorescent photons through the automatic fluorescence spectrum analysis device to obtain the fluorescence spectrum of the target sample, and determine the ore composition and content in the target sample based on the fluorescence spectrum, so as to determine the taste information of the target sample. After the detection device 130 obtains the ore taste information, it can upload it to a remote computer so that the ore grade at different locations in the mine and the ore grade at different depths under each location can be determined based on the sample information provided by the detection device 130, so that the ore grade of the entire mine can be summarized and analyzed.

[0066] The sample testing method provided in this embodiment enables fully automated processing from sample collection to grinding, screening, packaging, and testing, improving ore testing efficiency and accuracy and reducing errors caused by human intervention. It also enables rapid acquisition of ore grade information at different locations and depths within the mine, providing greater real-time performance and thus improving the overall efficiency of ore sample testing.

[0067] In some embodiments, the ore testing equipment 100 may include: a collection device 170 for collecting target samples that have completed testing, and the sample testing method may further include: step S350 of receiving and storing the target samples that have completed testing through the collection device 170. The target samples that have completed testing by the detection device 130 can be transmitted to the collection device 170, so that the target samples that have completed testing are collected and stored by the collection device 170, thereby facilitating manual removal of the target samples stored in the collection device 170 for sorting and archiving. Through this embodiment, the centralized collection and storage of target samples that have completed testing can be performed by the collection device 170 according to step S350, which can avoid sample loss or confusion, improve the efficiency of sample management, and facilitate subsequent manual sampling, sorting and archiving operations, thereby improving the overall work efficiency of the ore testing equipment 100 and the standardization of sample processing.
