Description

Technical Field

[0001] The invention relates to ore processing equipment and a processing method, and in particular to a sorting device and a state monitoring and repair and debugging method thereof. Background Art

[0002] At present, the intelligent ore sorting system can only determine whether the working state of the system is normal by detecting the sorting results. When a system operation failure is found, the operator needs to shut down the system before performing equipment debugging, which is very cumbersome. The general steps of debugging work are to adjust the system working parameters or repair and replace the hardware according to the sorting results. The debugging methods include but are not limited to modifying the algorithm, adjusting the tube voltage and tube current, and correcting the position of the visual sensor. After debugging the system working parameters once, the intelligent ore sorting system cannot achieve the expected goals immediately. Based on the single variable principle, the operator needs to collect the ore that was being sorted in the system before the shutdown debugging, and put it back into the system, and evaluate whether the system is debugged to the ideal working condition according to the new sorting results; if the ideal working condition is not reached, the above debugging process needs to be performed again, and multiple rounds are repeated until the ideal state is reached. At this time, the sorting system can enter the normal working state.

[0003] The above method has the following defects: First, the system working status can only be judged by manually testing the sorting results. However, considering economic factors, the operator cannot always test every batch of sorted ore, which will lead to the problem that the sorting system fails but cannot be promptly checked. Before the problem is found, the sorting equipment still discharges ore normally. Under this condition, the discharged ore cannot meet the target waste requirements, which will pollute the qualified ore discharged normally before the problem occurs, seriously affecting the production capacity of the subsequent production process; Second, after the newly purchased equipment arrives at the mine, the original operating parameters must be set according to the on-site conditions. Since the properties of the ore produced by each mine are very different, there is no historical operating data to refer to, and the best operating parameters can only be determined through repeated rounds of on-site debugging. Since most equipment is used in an open-pit mine environment and is not equipped with large-scale lifting equipment, it is necessary to manually collect the ore produced during each round of debugging and put it into the equipment again during the on-site debugging process. At the same time, the height of the ore intelligent sorting system is generally more than 2m, and the length is generally more than 5m. The total weight of ore required for each round of debugging is generally more than 5 tons, resulting in a large amount of manpower required to collect, transport and put ore during the debugging process, which greatly increases the cost of use. For the sorting systems on the market, the process of setting the original operating parameters generally takes several months. In addition, the existing sorting system does not have an automatic correction function, so during the debugging process, the manufacturer's technicians need to participate throughout the process, which further increases the cost of the user.

[0004] Third, after the original operating parameters are set, since the properties of the ore put into the sorting system will continue to change with the mining situation, the operating parameters of the sorting system need to be debugged from time to time during the operation of the equipment to match the real-time sorting needs. As mentioned in the second point, each debugging requires multiple rounds of start-up and shutdown, manual ore handling, and support from manufacturer technicians. In addition, the shutdown debugging during the production process is different from the initial original operating parameter debugging after purchasing the machine, which will affect the upstream and downstream production lines, causing production stagnation and seriously weakening production capacity; Fourth, the working environment of the sorting equipment is harsh. It is in a dusty and humid mining environment for a long time, and most of the components are constantly subjected to the impact of ore, which easily leads to various mechanical and electrical failures that do not affect the operation of the equipment but affect the sorting results, such as the speed drop of the ore conveyor belt, the position offset of the camera, the lens sticking to dust, the cloth jamming, etc. Since the sorting system on the market has no automatic correction function, the operator can only spend a lot of time to repair such problems by stopping the machine for debugging, which further weakens the production capacity.

[0005] In addition, after long-term mining, easy-to-mine and easy-to-select rich ore resources have become increasingly scarce, and mining companies have to turn to processing ores with lower grades and complex compositions, which not only increases mining costs, but also imposes a greater burden on the environment. Faced with this dilemma, how to efficiently utilize limited mineral resources while reducing environmental pressure has become a core issue restricting the sustainable development of the mining industry. The innovative application of photoelectric sorting and waste disposal technology provides a new approach to solving the above problems. By integrating a highly sensitive optical recognition system with a precise mechanical separation device, this technology can accurately discard the raw ore at the front end of ore processing, effectively remove useless impurities, directly improve the grade of the selected ore, and reduce subsequent processing energy consumption and costs. By introducing photoelectric sorting and waste disposal equipment in mining operations, it can not only significantly improve the comprehensive resource recovery rate and increase economic benefits, but also substantially alleviate the pressure of resource depletion, winning a precious "second life" for mines. Although photoelectric sorting and waste disposal technology has brought revolutionary progress to the efficient utilization of mining resources, it still faces a series of challenges in practical applications, especially the uniformity and orderliness of the feed. Since ore raw materials are prone to accumulation and overlap during transportation, this directly affects the optical sensor's ability to accurately identify them. When faced with dense, overlapping materials, the sensor has difficulty accurately distinguishing the optical characteristics of individual ore particles, resulting in a significant reduction in sorting efficiency and accuracy. The execution of the injection during the sorting process is also restricted. Considering that there is a necessary minimum time interval between two injection actions to ensure accuracy and effect, the accumulation of materials not only affects the choice of injection timing, but may also cause some target materials to fail to be separated in time, further reducing the overall sorting efficiency. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a sorting device which does not require shutdown during the debugging process, does not require manual ore handling, and greatly reduces the cost of the debugging process.

[0011] The material block size identification mechanism includes a multi-line laser radar, and the photoelectric imaging mechanism includes an X-ray transmission detector.

[0012] The sorting conveying track includes a first conveying track and a second conveying track. The material mixing mechanism includes a plurality of partitions spaced apart along the width direction of the first conveying track. A material mixing channel is formed between adjacent partitions. The material mixing mechanism is connected to a material mixing driving mechanism to realize reciprocating motion along the width direction of the first conveying track. The material block size identification mechanism, the photoelectric imaging mechanism and the blowing mechanism are arranged in sequence along the conveying direction of the second conveying track.

[0013] The material scrambling mechanism also includes an upper cover plate, the upper side of each of the partitions is connected to the upper cover plate, the upper cover plate is hinged to a limit plate at the inlet end of each of the material scrambling channels, an elastic member is provided between the limit plate and the upper cover plate, and a limit member for limiting the rotation angle is provided on the lower side of the limit plate, the material scrambling drive mechanism includes a rotary drive member, a turntable, a connecting rod, a guide rail and a sliding seat provided on the guide rail, the turntable is connected to the rotary drive member, one end of the connecting rod is hinged to the turntable and the hinge is offset from the center of the turntable, the other end of the connecting rod is hinged to the sliding seat, and the upper cover plate is connected to the sliding seat; The cam is provided with a plurality of connecting rods, each of which ... Or, at least one connecting plate is provided downstream of the partition, and a plurality of levers are provided on the connecting plate.

The bending rod is connected to the rotating drive member, one end of each connecting rod is hinged to the bending rod, and the other end of each connecting rod is hinged to each sliding seat one by one. Each connecting plate is connected to each sliding seat one by one. When there are multiple connecting plates, the moving directions of two adjacent connecting plates are opposite.

[0014] A method for status monitoring and repair and debugging of the above-mentioned sorting equipment comprises the following steps: S100, judging whether there is a fault according to the operating parameter information of the sorting equipment in the working mode and the warning information of the sorting equipment; S200: If the sorting device has a fault, further determine the type of the fault and perform one of the following steps according to the type of the fault: S201, if the fault type is a first type fault, the corresponding fault is repaired by stopping the machine for maintenance. After the fault is repaired, the switching mechanism is activated, the circulating conveying track is started, and the sorting equipment enters the debugging mode, so that the ore to be sorted re-enters the sorting conveying track through the circulating conveying track; in the debugging mode, it is determined whether the fault is solved, and after the fault is solved, the switching mechanism is reset, the circulating conveying track stops running, and the sorting equipment re-enters the working mode. If the fault cannot be solved, the fault type is changed to the first type fault and step S201 is executed; S202, if the fault type is a second type fault, the switching mechanism is activated, the circulating conveying track is started, and the sorting equipment enters the debugging mode to repair the corresponding fault in a non-stop maintenance mode; in the debugging mode, it is determined whether the fault is solved, and after the fault is solved, the switching mechanism is reset, the circulating conveying track stops running, and the sorting equipment re-enters the working mode; Among them, the first type of faults include hardware faults indicating mechanical structure damage or circuit damage in the operating parameter information or system warning information; the second type of faults include software faults indicating algorithm failure or incorrect working parameter settings in the operating parameter information or system warning information.

If the difference between the actual scrap rate and the target scrap rate of the standard ore sample is within the preset range, it means that the fault has been resolved.

[0016] If the fault still exists, determine the type of fault, and execute step S201 or step S202 to repair the fault according to whether the fault type is a first type fault or a second type fault. Repeat the execution until the fault has been resolved, then reset the switching mechanism, stop the circulating conveying track, and re-enter the working mode.

[0017] The working condition parameter information includes one or more of the theoretical amount of sorted ore derived based on the working parameters set by the sorting equipment, the actual amount of discarded ore derived by collecting images from the camera at the blowing mechanism, and the brightness information of the sorting conveying track used for conveying ore flow in the sorting equipment under the photoelectric imaging mechanism; The warning information includes one or more of the following: the sorting conveying track is stuck, the air tank pressure of the blowing mechanism is insufficient, the jetting of the blowing port of the blowing mechanism is delayed, and the nozzle is blocked.

[0018] Compared with the prior art, the advantages of the present invention are: the sorting equipment disclosed in the present invention, First, in the normal working mode, the ore enters the material leveling mechanism driven by the sorting conveyor track. On the one hand, the ore can enter the sorting process in a uniform and dispersed state, significantly improving the accuracy and stability of the material size identification mechanism, laying the foundation for subsequent precise sorting; on the other hand, considering the influence of the time interval limit of the two blowing operations of the blowing mechanism on the sorting accuracy, this can also optimize the ore flow, realize the queuing feeding along the width direction of the sorting conveyor track, avoid the delay of the subsequent blowing mechanism and the loss of accuracy, ensure that each blowing of the blowing mechanism can accurately act on the target ore, improve the overall sorting efficiency, and avoid the situation where some nozzles of the blowing mechanism are overused while some nozzles are not used, thereby improving the overall life of the nozzles; Second, when it is necessary to adjust the relevant parameters of the sorting equipment, it is only necessary to switch the mechanism action. There is no need to stop the machine and manually transport the ore. The ore will no longer be discharged, but will return to the feed end of the sorting conveyor track through the circulating conveyor track for circulation, and the next round of debugging will be carried out uninterruptedly. When the debugging is completed, it is only necessary to switch the mechanism action again, and the ore will resume normal discharge, which can greatly reduce the difficulty and time cost of the debugging process, make the debugging process flexible, and reduce the impact of debugging behavior on normal production.

[0019] In summary, the sorting equipment disclosed in the present invention helps to solve the problems that the existing intelligent ore sorting system cannot monitor in real time whether the working status is normal, the system must be shut down when debugging the working parameters, any fault requires shutdown and debugging to solve, the ore circulation operation is difficult during the debugging of the working parameters, and professional technicians need to participate in the whole process. The state monitoring and repair and debugging method of the sorting equipment disclosed in the present invention monitors the signals returned by each sensor in the system in real time, continuously judges the working state of the system, automatically switches to the circulation mode after identifying the fault, repeatedly adaptively adjusts, and automatically switches back to the normal operation mode after the repair is completed, thereby realizing the rapid and uninterrupted circulation of ore during the debugging of the working parameters of the sorting equipment, and at the same time, it can realize automatic detection and repair for most faults, and automatic debugging of the working parameters, which solves the problem that the traditional sorting system can only judge the system operation state and identify the system fault by manually checking the sorting results, and further solves the problem that the traditional sorting system needs to shut down for debugging and solve all faults, and requires on-site operation by the manufacturer's technical personnel, thereby ensuring that the equipment is in a normal state without fault at any time during the operation process, and greatly improving the stability of the discharge.

[0037] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Embodiment 1 Figures 1 to 7 and Fig. 9 An embodiment of the sorting equipment of the present invention is shown. The sorting equipment of this embodiment includes a sorting conveyor track 1 and a circulating conveyor track 5. The sorting conveyor track 1 is provided with a material leveling mechanism 2, a material block size identification mechanism 6, a photoelectric imaging mechanism 7 and a blowing mechanism 9 in sequence along the conveying direction. The discharge end of the sorting conveyor track 1 is docked with the feed end of the circulating conveyor track 5, and the discharge end of the circulating conveyor track 5 is docked with the feed end of the sorting conveyor track 1. The discharge end of the sorting conveyor track 1 is provided with a switching mechanism 8 for discharging or circulating the material. Among them, the sorting conveyor track 1 and the circulating conveyor track 5 preferably use conveyor belts. Of course, in other embodiments, the sorting conveyor track 1 and the circulating conveyor track 5 can also use conveyor plate chains, etc.

[0039] In the normal working mode of the sorting equipment of this embodiment, the ore enters the material leveling mechanism 2 driven by the sorting conveyor track 1, which can make the ore enter the sorting process in a uniform and dispersed state, significantly improve the accuracy and stability of the material block size identification mechanism 6, and lay the foundation for the subsequent precise sorting; on the other hand, considering the influence of the time interval limit of the two blowing operations of the blowing mechanism 9 on the sorting accuracy, it can also optimize the ore flow, realize the queuing feeding along the width direction of the sorting conveyor track 1, avoid the delay of the subsequent blowing timing and the loss of accuracy of the blowing mechanism 9, ensure that each round of blowing of the blowing mechanism 9 can accurately act on the target ore, improve the overall sorting efficiency, and at the same time avoid the situation where some nozzles of the blowing mechanism 9 are overused while some nozzles are not used, and improve the nozzle Overall life; when it is necessary to adjust the relevant parameters of the sorting equipment, that is, when the sorting equipment enters the debugging mode, the switching mechanism 8 is activated, the circulating conveyor track 5 is started, and the ore is no longer discharged but returns to the feeding end of the sorting conveyor track 1 through the circulating conveyor track 5 for circulation. This helps to solve the problems that the existing ore intelligent sorting system must be shut down when debugging working parameters, and the ore circulation operation is difficult during the debugging process, and professional technicians are required to participate in the whole process. There is no need to manually transport the ore sorted during the debugging process, and there is no need to shut down during the debugging process, which greatly reduces the time, labor and other costs of the debugging process. At the same time, by ensuring the single variable principle in the debugging process, the debugging result is more accurate, and the debugging process is flexible, reducing the impact of debugging behavior on normal production. Preferably, the circulating conveyor track 5 adopts a detachable structure (for example, the installation part of the sorting conveyor track 5 is fixed by bolts). When the sorting equipment is debugged, the circulating conveyor track 5 can be quickly disassembled; when it is necessary to debug again, the circulating conveyor track 5 can also be quickly installed without increasing the volume of the sorting part of the equipment (the sorting part includes the sorting conveyor track 1, the material leveling mechanism 2, the material block size identification mechanism 6, the photoelectric imaging mechanism 7 and the blowing mechanism 9).

[0040] Furthermore, in this embodiment, the switching mechanism 8 includes a baffle 81, and both ends of the baffle 81 are provided with a first swing rod 82 and a second swing rod 83 for driving the baffle 81 to swing up and down, and at least one of the first swing rods 82 or at least one of the second swing rods 83 is connected to a swing driving member (not shown in the figure, for example, it can be a motor, etc.). When the sorting equipment is in normal working mode, the baffle 81 can swing to the top of the sorting conveying track 1, and the ore can be discharged through the sorting conveying track 1; when the ore needs to be circulated, the swing driving member drives the first swing rod 82 or the second swing rod 83 connected thereto to swing, so that the baffle 81 moves to the front of the sorting conveying track 1 for blocking. Under the action of the first swing rod 82 and the second swing rod 83 at both ends, the movement process of the baffle 81 is smooth, and at the same time it can withstand the impact of the ore, and the structure is simple and reliable.

[0041] Furthermore, in this embodiment, the height of the discharge end of the sorting conveyor track 1 is greater than the height of the feed end of the circulating conveyor track 5, the discharge end of the sorting conveyor track 1 and the feed end of the circulating conveyor track 5 are connected through the first vibrating guide trough 51, the height of the discharge end of the circulating conveyor track 5 is greater than the height of the feed end of the sorting conveyor track 1, and the discharge end of the circulating conveyor track 5 and the feed end of the sorting conveyor track 1 are connected through the second vibrating guide trough 52. The circulating conveyor track 5 includes a horizontal conveyor track and a lifting conveyor track connected to the horizontal conveyor track. When the ore needs to be circulated, the swing drive member drives the first swing rod 82 or the second swing rod 83 connected thereto to swing, so that the baffle 81 moves to the front of the sorting and conveying track 1 for blocking. Under the action of the baffle 81, the ore falls to the first vibrating material guide trough 51 below. The first vibrating material guide trough 51 starts to transfer the ore to the circulating conveying track 5 (specifically the horizontal conveying track). The circulating conveying track 5 (specifically the lifting conveying track) transfers the ore to the second vibrating material guide trough 52. The second vibrating material guide trough 52 transfers the ore to the feeding end of the sorting and conveying track 1 (specifically the third vibrating material guide trough 13). Vibration (such as an electric vibrator, etc.) can speed up the ore discharge speed and prevent blockage. The structure is simple and reliable.

[0042] Furthermore, in the sorting equipment of the present embodiment, the sorting conveying track 1 includes a first conveying track 11 and a second conveying track 12, the material scrambling mechanism 2 includes a plurality of partitions 21 spaced apart along the width direction of the first conveying track 11, and a material scrambling channel 22 is formed between adjacent partitions 21, the material scrambling mechanism 2 is connected to a material scrambling drive mechanism 3 to realize reciprocating motion along the width direction of the first conveying track 11, and the material block size identification mechanism 6, the photoelectric imaging mechanism 7 and the blowing mechanism 9 are arranged in sequence along the conveying direction of the second conveying track 12.

[0043] Driven by the first conveying track 11, the ore enters the sizing channel 22 between the partitions 21 in the sizing mechanism 2, and the sizing drive mechanism 3 drives the sizing mechanism 2 to reciprocate along the width direction of the first conveying track 11. On the one hand, it can ensure that the ore enters the sorting process in a uniform and dispersed state, significantly improve the accuracy and stability of the material block size identification mechanism 6, and lay the foundation for subsequent precise sorting; on the other hand, considering the influence of the time interval limit of the two blowing operations of the blowing mechanism 9 on the sorting accuracy, this can also optimize the ore flow, realize the queuing feeding along the width direction of the first conveying track 11, avoid the delay of the subsequent blowing mechanism 9 and the loss of accuracy, ensure that each round of blowing of the blowing mechanism 9 can accurately act on the target ore, improve the overall sorting efficiency, and at the same time avoid the excessive use of some nozzles of the blowing mechanism 9 while some nozzles are not used, thereby improving the overall life of the nozzles.

[0044] See Fig.12 As a preferred embodiment, the material block size identification mechanism 6 includes a multi-line laser radar. The ore surface can be scanned by a multi-line laser radar to obtain the three-dimensional point cloud data of the ore on the second conveying track 12, and then the minimum bounding box of a single ore is calculated to obtain the block sizes of different ores, which helps to assist the blowing mechanism 9 to achieve precise blowing (ores of different block sizes require different blowing forces. By identifying the block size information of the ore, the blowing time of the blowing mechanism 9, the number of blowing ports and other parameters can be optimized), further improving the sorting efficiency. Of course, in other embodiments, other methods can also be used to realize ore block size identification, such as multi-eye vision, using cameras at different angles to reconstruct the three-dimensional point cloud of the ore, and then obtain its block size information.

[0045] As a preferred embodiment, the photoelectric imaging mechanism 7 includes an X-ray transmission detector. Without destroying the material, the internal information of the material can be reflected by the attenuation information of the X-rays after penetration. The grayscale value of the imaging picture represents the absorption of X-rays by the ore, which is easily affected by the thickness of the ore. By decoupling the results obtained by the material block size identification mechanism 6 and the X-ray transmission image obtained by the photoelectric imaging mechanism 7 at the pixel level, the grayscale value of each pixel affected by the thickness is corrected and compensated, thereby avoiding the influence of thickness, achieving a more accurate classification of the ore, and determining whether it is waste rock. Finally, the blowing mechanism 9 realizes precise blowing according to the ore block size information and ore category, and the system structure is reasonable and effective.

[0046] Furthermore, in this embodiment, a third vibrating material guide trough 8 is provided at one end of the first conveying track 11 away from the second conveying track 12. Figure 3The third vibrating guide trough 13 is connected to the upper end of the first conveying track 11, and the second conveying track 12 is connected to the lower end of the first conveying track 11. The ore can be added into the third vibrating guide trough 8, and then enters the storage bin 4 under the action of gravity, which has a simple and reliable structure.

[0047] See Fig. 9 Furthermore, in this embodiment, the material leveling mechanism 2 also includes an upper cover plate 23, the upper side of each partition 21 is connected to the upper cover plate 23, the upper cover plate 23 is hinged with a limit plate 24 at the entrance end of each material leveling channel 22, an elastic member 25 (such as a coil spring, elastic rubber, etc.) is provided between the limit plate 24 and the upper cover plate 23, and a limit member 241 (such as a limit rod, a limit block, etc.) for limiting the rotation angle is provided on the lower side of the limit plate 24. The limit member 241 constrains the movement of the limit plate 24 to limit its downward rotation range, and the minimum height of the limit plate 24 is the maximum size of the feed ore. The elastic member 25 can increase the height of the material leveling channel 22 when there is too much ore in a certain material leveling channel 22 and squeezes the limit plate 24 up and down, thereby speeding up the passing speed of the ore while limiting the height of the incoming material, and realizing the normal feeding of the ore, and the structure is reasonable and effective.

[0048] Furthermore, in the present embodiment, the material leveling drive mechanism 3 includes a rotating drive member 31, a turntable 32, a connecting rod 33, a guide rail 34 and a sliding seat 35 arranged on the guide rail 34, the turntable 32 is connected to the rotating drive member 31, one end of the connecting rod 33 is hinged to the turntable 32 and the hinge point is offset from the center of the turntable 32, the other end of the connecting rod 33 is hinged to the sliding seat 35, and the upper cover plate 23 is connected to the sliding seat 35. When working, the rotating driving member 31 drives the turntable 32 to rotate. Since the hinge between the connecting rod 33 and the turntable 32 deviates from the center of the turntable 32, the turntable 32 can drive the sliding seat 35 to move back and forth along the guide rail 34 through the connecting rod 33 when the turntable 32 rotates. The guide rail 34 provides a guiding function for the sliding seat 35 to ensure a smooth and smooth movement process to avoid deviation. The sliding seat 35 drives the upper cover plate 23 and the partitions 21 connected thereto to move back and forth along the width direction of the first conveying track 11, thereby optimizing the flow of ore and allowing the ore to enter the subsequent sorting process in a uniform and dispersed state. Preferably, two guide rails 34 are provided to further enhance the guiding effect.

[0049] As a preferred embodiment, the rotating driving member 31 is a speed regulating motor, and a reducer 36 is provided between the speed regulating motor and the rotating disk 32. The speed regulating motor is used as a power source, and the speed regulating motor and the reducer 36 jointly ensure the speed change requirement, and the movement speed of the partition 21 can be conveniently controlled.

[0050] In this embodiment, the first conveying track 11 is also provided with a storage bin 4 upstream of the material leveling mechanism 2, and the end of the material leveling mechanism 2 close to the storage bin 4 is provided with side collecting plates 27 extending toward the outside of the first conveying track 11 on both sides, and an upper collecting plate 28 extending upward is connected between the two side collecting plates 27.

[0051] Preferably, the storage bin 4 is formed by the enclosed plate parts, with a large top feed inlet and a small bottom discharge outlet, which is convenient for controlling the discharge speed of the material and is also conducive to the subsequent material leveling. The width of the bottom discharge outlet of the storage bin 4 is the same as the effective bandwidth of the conveyor belt, and the length (the dimension along the conveying direction of the conveyor belt) is consistent with the maximum particle size of the ore after crushing, so as to avoid the material stacking and overlap during discharge as much as possible. Preferably, vibrators 41 are arranged on both sides of the storage bin 4, and more preferably, electric vibrators. After power is turned on, the vibrators 41 vibrate, driving the storage bin 4 to vibrate, thereby accelerating the material discharge speed of the storage bin 4, preventing the material from blocking the discharge outlet, and assisting in uniformly dispersing the feeding. More preferably, a vibration reduction component (such as a rubber pad, a spring, etc.) is arranged between the storage bin 4 and the conveyor belt to reduce the vibration caused by the vibrator 41 and transmit it to the conveyor belt.

[0052] The two side collecting plates 27 cooperate to form a bell mouth, which is wide in front and narrow in the back along the moving direction of the conveyor belt, ensuring that the materials can be concentrated in the bell mouth after falling from the storage bin 4 and flowing through the conveyor belt. Therefore, the front width of the bell mouth formed by the two side collecting plates 27 should be greater than the width of the conveyor belt, and the rear narrow part should be less than or equal to the width of the conveyor belt, ensuring that all materials can be concentrated and not leaked. The bottom surfaces of the two side collecting plates 27 are parallel to the inclined conveyor belt plane, and there is a small distance between the two. The distance is usually set to one tenth of the maximum particle size of the ore, so that it is not obstructed when reciprocating. The two side collecting plates 27 are fixed to the upper collecting plate 28, the upper end of the upper collecting plate 28 is far from the conveyor belt plane, and the lower end is close to the conveyor belt plane, which preliminarily limits the height of the material flow process and avoids overlapping and stacking of materials. Specifically, the two side collecting plates 27 are connected to the outermost partition plate 21, and the upper collecting plate 28 is connected to the upper cover plate 23, and can move back and forth as a whole along the width direction of the first conveyor track 11.

[0053] As a preferred embodiment, the first conveying track 11 is arranged at an angle and the height gradually decreases along the conveying direction. The inclination angle of the first conveying track 11 is 5° to 25°, and the inclination angle is further preferably 10° to 15°. The surface of the first conveying track 11 is provided with a pattern for increasing friction (not shown in the figure). On the one hand, the incoming ore falls onto the conveying belt and flows along the moving direction of the conveying belt. At the same time, the ore can accelerate the flow through the gravity component. On the other hand, the conveying belt adopts a patterned belt. During the material conveying process, the friction between the material and the conveying belt is increased, which is convenient for controlling the stability of the material and provides a basis for subsequent orderly feeding.

[0054] Embodiment 2 Figures 8 to 10 Another embodiment of the sorting device of the present invention is shown. The sorting device of this embodiment is basically the same as that of the first embodiment, except that: In this embodiment, the partition 21 is hinged with a swing plate 211 at the outlet end of the material mixing channel 22, and the upper sides of the swing plates 211 are connected by a connecting plate 26, and the material mixing drive mechanism 3 is connected to the connecting plate 26. That is, in this embodiment, the partition 21 no longer moves back and forth, but the material mixing drive mechanism 3 drives the swing plates 211 to swing back and forth along the width direction of the first conveying track 1 through the connecting plate 26. After the ore passes through the material mixing channel 22, the swing plate 211 can also optimize the flow of the ore, so that the ore enters the subsequent sorting process in a uniform and dispersed state.

[0055] Furthermore, in the present embodiment, three connecting columns 261 are provided on the connecting plate 26 along the length direction, the material leveling driving mechanism 3 includes a rotating driving member 31, a turntable 32, a connecting rod 33, a guide rail 34 and three sliding seats 35 provided on the guide rail 34, the sliding seat 35 is provided with an arc guide groove 351, the three connecting columns 261 are respectively passed through the three arc guide grooves 351, the turntable 32 is connected to the rotating driving member 31, one end of the connecting rod 33 is hinged to the turntable 32 and the hinge point deviates from the center of the turntable 32, and the connecting column 261 located in the center is passed through the other end of the connecting rod 33. During operation, the rotating driving member 31 drives the turntable 32 to rotate. Since the hinge between the connecting rod 33 and the turntable 32 deviates from the center of the turntable 32, the connecting rod 33 can drive the connecting column 261 located in the center to move when the turntable 32 rotates. The connecting plate 26 and the connecting columns 261 on both sides move with the connecting column 261 in the center, thereby driving the swing plates 211 under the connecting plate 26 to swing back and forth along the width direction of the first conveying track 1. The sliding seat 35 moves back and forth along the guide rail 34 driven by the connecting column 261. The guide rail 34 provides a guiding effect for the sliding seat 35 to ensure that the movement process is stable and smooth and avoids deviation. The arc guide groove 351 on the sliding seat 35 provides a guiding effect for the connecting column 261, thereby optimizing the flow of ore and allowing the ore to enter the subsequent sorting process in a uniform and dispersed state. The structure is reasonable and effective.

[0056] Participate specifically Fig.10 Furthermore, in this embodiment, rolling elements 352 (such as ball bearings) are arranged around the circular arc guide groove 351, which can reduce the friction resistance and wear between the circular arc guide groove 351 and the connecting column 261, and the structure is simple and reliable.

[0057] Embodiment 3 Fig.11Another embodiment of the sorting device of the present invention is shown. The sorting device of this embodiment is basically the same as the first embodiment and the second embodiment, except that: In this embodiment, two connecting plates 26 are provided downstream of the partition 21, and multiple shifting rods 262 are provided on the connecting plates 26. Preferably, the multiple shifting rods 262 are staggered (or not colinear) along the movement direction of the conveyor belt, which is beneficial to enhance the material leveling effect. The material leveling drive mechanism 3 includes a rotating drive member 31, a bending rod 321, two connecting rods 33, two guide rails 34 and a sliding seat 35 provided on the guide rail 34. The bending rod 321 is connected to the rotating drive member 31, one end of each connecting rod 33 is hinged to the bending rod 321, and the other end of each connecting rod 33 is hinged to each sliding seat 35 in a one-to-one correspondence. Each connecting plate 26 is connected to each sliding seat 35 in a one-to-one correspondence, and the moving directions of two adjacent connecting plates 26 are opposite. During operation, the rotating driving member 31 drives the bending rod 321 to rotate. Since the connecting rod 33 is hinged to the bending rod 321, the connecting rod 33 can drive the sliding seat 35 to move back and forth along the guide rail 34 when the bending rod 321 rotates, and the movement of different connecting rods 33 can be asynchronous. The guide rail 34 provides a guiding function for the sliding seat 35 to ensure that the moving process is stable and smooth to avoid deviation. The sliding seat 35 drives the connecting plate 26 and the connected levers 262 to move back and forth along the width direction of the first conveying track 11, thereby optimizing the flow of ore and allowing the ore to enter the subsequent sorting process in a uniform and dispersed state. Since the moving directions of the two adjacent connecting plates 26 are opposite, the two cooperate with each other to further enhance the material leveling effect. Of course, in other embodiments, the number of connecting plates 26 can also be adjusted (the connecting rod 33, the guide rail 34 and the sliding seat 35 can be adjusted accordingly).

[0058] Embodiment 4 like Fig.13 As shown, the state monitoring and repair debugging method of the sorting equipment of this embodiment includes the following steps: S100, judging whether there is a fault according to the operating parameter information of the sorting equipment in the working mode and the warning information of the sorting equipment; S200: If the sorting device has a fault, further determine the type of the fault and perform one of the following steps according to the type of the fault: S201, if the fault type is a first type fault, the corresponding fault is repaired by stopping the machine for maintenance (for example, mechanical mechanism damage, circuit damage, etc., which requires stopping the machine for maintenance to repair), and after the fault is repaired, the switching mechanism 8 is activated, the circulating conveying track 5 is started, and the sorting equipment enters the debugging mode, so that the ore to be sorted re-enters the sorting conveying track 1 through the circulating conveying track 5; in the debugging mode, it is determined whether the fault is solved, and after the fault is solved, the switching mechanism 8 is reset, the circulating conveying track 5 stops running, and the sorting equipment re-enters the working mode; S202, if the fault type is a second type fault, the switching mechanism 8 is actuated, the circulating conveying track 5 is started, and the sorting device enters the debugging mode to repair the corresponding fault in a non-stop maintenance manner; in the debugging mode, it is determined whether the fault is resolved, and after the fault is resolved, the switching mechanism 8 is reset, the circulating conveying track 5 stops running, and the sorting device re-enters the working mode. If the fault cannot be resolved, the fault type is converted to a first type fault and step S201 is executed; Among them, the first type of faults include hardware faults indicating mechanical structure damage or circuit damage in the operating parameter information or system warning information; the second type of faults include software faults indicating algorithm failure or incorrect working parameter settings in the operating parameter information or system warning information.

[0059] In this embodiment, in step S201 and step S202, determining whether the fault is resolved includes: Add artificially synthesized standard ore samples with known mineral characteristics and marked labels to the sorting equipment. If the difference between the actual scrap rate and the target scrap rate of the standard ore sample is within the preset range, it means that the fault has been solved, otherwise it means that the fault has not been solved. When the difference between the actual scrap rate and the target scrap rate is too large, or when the equipment determines that the existing operating parameters are insufficient to achieve the target scrap rate, turn on the debugging mode to automatically adjust the equipment working parameters such as the voltage and current of the photoelectric imaging mechanism 7 and the transportation speed of the sorting conveyor track 5 until the actual scrap rate meets the standard. Among them, the actual scrap rate is defined as a value obtained by monitoring the ore flow, volume evaluation, grayscale calculation and other methods. At the same time, the equipment determines whether the existing operating parameters can achieve the target scrap rate based on these data. The target scrap rate is formulated according to the production plan.

[0060] In this embodiment, If the fault still exists, determine the type of fault, and execute step S201 or step S202 to repair the fault according to whether the fault type is a first type fault or a second type fault. Repeat the execution until the fault has been resolved, then reset the switching mechanism 8, stop the circulating conveying track 5, and re-enter the working mode.

[0061] In this embodiment, The working condition parameter information includes one or more of the running speed of the sorting and conveying track 1, the tube voltage and tube current of the photoelectric imaging mechanism 7, the theoretical number of sorted ores derived based on the working parameters set by the sorting equipment, the actual number of discarded ores derived through the image collected by the camera at the blowing mechanism 9, and the brightness information of the sorting and conveying track 1 used for conveying the ore flow in the sorting equipment under the photoelectric imaging mechanism 7; The warning information includes one or more of the following: the sorting and conveying track 1 is stuck, the air tank pressure of the blowing mechanism 9 is insufficient, the jetting of the blowing port of the blowing mechanism 9 is delayed, and the nozzle is blocked.

[0062] The status monitoring and repair and debugging method disclosed in the present embodiment monitors the signals returned by each sensor in the equipment in real time, continuously judges the working status of the equipment, automatically switches to the circulation mode after identifying a fault, repeatedly makes adaptive adjustments, and automatically switches back to the normal working mode after the repair is completed, thereby realizing the rapid and uninterrupted circulation of ore during the process of debugging the working parameters of the sorting equipment. At the same time, most faults can be automatically detected and repaired, and the working parameters can be automatically debugged, which solves the problem that the traditional sorting system can only judge the system operation status and identify system faults by manually checking the sorting results. It further solves the problem that the traditional sorting system needs to shut down for debugging and solve all faults, and requires on-site operation by the manufacturer's technical personnel, thereby ensuring that the equipment is in a normal state without faults at any time during the operation process, and greatly improving the stability of the discharge.

[0063] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
