Description

Technical Field

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

[0002] At present, the intelligent ore sorting system can only judge whether the working state of the system is normal by detecting the sorting result. When a system operation failure is found, the operator needs to perform equipment debugging work after the machine stops, and the operation is very cumbersome. The general steps of the debugging work are to adjust the system working parameters accordingly according to the sorting result, or repair and replace the hardware. 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 vision sensor. After adjusting the system working parameters once, the intelligent ore sorting system does not immediately reach the expected goal. Based on the principle of single variable, at this time, the operator needs to collect the ore 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 result; if the ideal working condition is not reached, the above debugging process needs to be performed again, and it cycles multiple rounds until the ideal state, and then the sorting system can enter the normal working state.

[0003] The defects of the above method are as follows:

[0004] First, at present, the working state of the system can only be judged by manually detecting the sorting result. Considering economic factors, the operator cannot always detect each batch of sorted ore, which will lead to the problem that the sorting system fails but cannot be checked in time. Before the problem is detected, the sorting equipment still discharges ore normally. The ore discharged in this state cannot meet the target waste rejection requirements, and will pollute the qualified ore that was discharged normally before the problem occurred, seriously affecting the production capacity of the subsequent production process;

[0005] 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 ore properties produced by each mine are very different, there is no historical operating data for reference, and the best operating parameters can only be determined through multiple rounds of on-site debugging. Since most equipment is used in the open-pit mine environment and does not have large lifting equipment, during the on-site debugging process, it is necessary to manually collect the ore produced in each round of debugging and put it back into the equipment. At the same time, the height of the intelligent ore sorting system generally exceeds 2m, the length generally exceeds 5m, and the total weight of the ore required for each round of debugging generally exceeds 5 tons, resulting in a large amount of manpower being required to collect, transport and put the ore during the debugging process, greatly increasing the use cost. For the sorting systems on the market, the process of setting the original operating parameters generally takes several months. In addition, the existing sorting systems do not have an automatic correction function. Therefore, during the debugging process, the technical personnel of the manufacturer need to participate throughout the process, which further increases the cost of the user.

[0006] Thirdly, after the original operating parameters are set, since the properties of the ore fed into the sorting system will constantly change with the mining conditions of the mine, during the operation of the equipment, it is necessary to debug the working parameters of the sorting system irregularly to match the real-time sorting requirements. As described in the second point, each debugging requires multiple rounds of startup and shutdown, manual handling of ore, and the support of manufacturer's technical personnel. In addition, the shutdown debugging during the production process is different from the initial debugging of the original operating parameters after purchasing the machine, which will affect the upstream and downstream production lines, cause production stagnation, and seriously weaken the production capacity;

[0007] Fourthly, the working environment of the sorting equipment is harsh. It is in a mine environment with high dust and high humidity for a long time, and most components continuously bear the impact of ore, which is prone to various mechanical and electrical failures that do not affect the operation of the equipment but affect the sorting results, such as the belt speed reduction of the ore conveyor belt, the deviation of the camera position, the adhesion of dust on the lens, and the cloth jamming. Since there is no automatic correction function in the sorting systems on the market, the operator can only spend a lot of time to repair such problems by means of shutdown debugging, further weakening the production capacity.

[0008] In addition, after long-term mining, the easily mined and easily selected rich ore resources are gradually scarce. Mining enterprises have to turn to processing ores with lower grades and complex compositions, which not only increases the mining cost but also causes a greater burden on the environment. Facing this dilemma, how to efficiently utilize limited mineral resources while reducing the environmental pressure has become the core issue restricting the sustainable development of the mining industry. The innovative application of the optoelectronic sorting and waste rejection technology provides a new idea for solving the above problems. By integrating a highly sensitive optical recognition system and a precise mechanical separation device, this technology can accurately reject waste from the raw ore at the front end of ore processing, effectively remove useless impurities, directly improve the grade of the ore to be selected, and reduce the energy consumption and cost of subsequent processing. By introducing optoelectronic sorting and waste rejection equipment in mine operations, not only can the comprehensive resource recovery rate be significantly improved, the economic benefits be increased, but also the pressure of resource depletion can be substantially alleviated, winning a precious "second life" for the mine. Although the optoelectronic sorting and waste rejection technology has brought revolutionary progress to the efficient utilization of mine resources, it still faces a series of challenges in practical applications, especially the problems of the uniformity and orderliness of the feed. Since the ore raw materials are prone to accumulation and overlap during transportation, this directly affects the accurate recognition ability of the optical sensors. When facing dense and overlapping materials, the sensors are difficult to accurately distinguish the optical characteristics of individual ore particles, resulting in a significant reduction in the sorting efficiency and accuracy. The blowing execution during the sorting process is also restricted. Considering the necessary minimum time interval between two blowing actions to ensure accuracy and effect, the accumulation of materials not only affects the selection of the blowing timing but also may cause some target materials to fail to be separated in time, further reducing the overall sorting efficiency. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a sorting device that does not require shutdown during debugging, does not require manual handling of ores, and greatly reduces the cost during the debugging process.

The material leveling mechanism is connected with a material leveling driving mechanism to realize reciprocating movement along the width direction of the first conveyor 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 conveyor track.

[0018] The material leveling mechanism further includes an upper cover plate. The upper sides of the partition plates are connected to the upper cover plate. A limiting plate is hinged at the entrance end of each material leveling channel on the upper cover plate. An elastic member is provided between the limiting plate and the upper cover plate. A limiting member for restricting the rotation angle is provided on the lower side of the limiting plate. The material leveling driving mechanism includes a rotation driving member, a turntable, a connecting rod, a guide rail, and a sliding seat provided on the guide rail. The turntable is connected to the rotation driving member. One end of the connecting rod is hinged to the turntable and the hinge point is offset from the center of the turntable. The other end of the connecting rod is hinged to the sliding seat. The upper cover plate is connected to the sliding seat;

[0019] Or, a swing plate is hinged at the exit end of the material leveling channel on the partition plate. The upper sides of the swing plates are connected through a connecting plate. The material leveling driving mechanism is connected to the connecting plate. A plurality of connecting columns are arranged along the length direction on the connecting plate.

An arc-shaped guiding groove is provided on the sliding seat. The plurality of connecting columns are respectively inserted into the plurality of arc-shaped guiding grooves in a one-to-one correspondence. Rolling members are provided around the arc-shaped guiding groove. The turntable is connected to the rotation driving member. One end of the connecting rod is hinged to the turntable and the hinge point is offset from the center of the turntable. The connecting column located at the center is inserted into the other end of the connecting rod;

[0020] Or, at least one connecting plate is provided downstream of the partition plate. A plurality of dial rods are provided on the connecting plate.

Each connecting plate is respectively connected to each sliding seat in a one-to-one correspondence. When there are multiple connecting plates, the moving directions of adjacent two connecting plates are opposite.

[0021] A method for monitoring the state and repairing and debugging of the above sorting equipment includes the following steps:

[0022] S100, judging whether there is a fault according to the working condition parameter information and sorting equipment warning information of the sorting equipment in the working mode;

[0023] S200, if there is a fault in the sorting equipment, further judging the type of the fault and performing one of the following steps according to the type of the fault:

[0024] S201. If the fault type is the first type of fault, repair the corresponding fault in the way of shutdown for maintenance. After the fault is repaired, switch the mechanism to actuate, start the circulating conveyor track, and the sorting equipment enters the debugging mode. Make the ore to be sorted re-enter the sorting conveyor track through the circulating conveyor track. In the debugging mode, judge whether the fault is solved. After the fault is solved, switch the mechanism to reset, stop the circulating conveyor track, and the sorting equipment re-enters the working mode. If the fault cannot be solved, convert the fault type to the first type of fault and execute step S201.

[0025] S202. If the fault type is the second type of fault, switch the mechanism to actuate, start the circulating conveyor track, and the sorting equipment enters the debugging mode to repair the corresponding fault in the way of non-stop maintenance. In the debugging mode, judge whether the fault is solved. After the fault is solved, switch the mechanism to reset, stop the circulating conveyor track, and the sorting equipment re-enters the working mode.

[0026] Among them, the first type of fault includes hardware faults indicating mechanical structure damage or circuit damage in the working condition parameter information or system warning information; the second type of fault includes software faults indicating algorithm faults or incorrect working parameter settings in the working condition parameter information or system warning information.

[0027] As a further improvement of the above technical solution:

[0028] In steps S201 and S202, judging whether the fault is solved includes:

[0029] Add a standard ore sample that is artificially synthesized, with all known ore properties and marked, to the sorting equipment. If the difference between the actual waste rejection rate and the target waste rejection rate of the standard ore sample is within the preset range, it means the fault has been solved.

[0030] If the fault still exists, judge the type of the fault, and execute step S201 or step S202 corresponding to the first type of fault or the second type of fault according to the fault type to repair the fault. Repeat the execution until the fault has been solved, then switch the mechanism to reset, stop the circulating conveyor track, and the sorting equipment re-enters the working mode.

[0031] The working condition parameter information includes one or more of the theoretical quantity of ore to be sorted derived from the working parameters set for the sorting equipment, the actual quantity of waste ore derived from the images collected by the camera at the blowing mechanism, and the brightness information of the sorting conveyor track for transporting the ore flow in the photoelectric imaging mechanism of the sorting equipment.

[0032] The warning information includes one or more of the sorting conveyor track being stuck, the air tank pressure of the blowing mechanism being insufficient, the jet delay of the blowing port of the blowing mechanism, and the nozzle being blocked.

[0033] Compared with the prior art, the advantages of the present invention are as follows: The sorting device disclosed by the present invention,

[0034] First, in the normal working mode, the ore enters the material leveling mechanism driven by the sorting and conveying track. On the one hand, it can make the ore enter the sorting process in a uniform and dispersed state, significantly improving the accuracy and stability of the material size recognition mechanism, laying a 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 queuing feeding along the width direction of the sorting and conveying track, avoid the delay of the blowing timing and the loss of accuracy of the subsequent blowing mechanism, ensure that each blow of the blowing mechanism can accurately act on the target ore, improve the overall sorting efficiency, and at the same time avoid the situation of overuse of some nozzles and non-use of some nozzles of the blowing mechanism, and improve the overall life of the nozzles;

[0035] Second, when it is necessary to adjust the relevant parameters of the sorting device, only the mechanism action needs to be switched, and there is no need to manually transport the ore after stopping the machine. The ore will no longer be discharged, but will return to the feeding end of the sorting and conveying track again through the circulating conveying track for circulation, and the next round of debugging will be carried out continuously. And when the debugging is over, only the mechanism action needs to be switched again, and the ore will resume normal discharging, which can greatly reduce the difficulty and time cost of the debugging process, make the debugging process flexible, and reduce the impact of the debugging behavior on normal production.

[0036] In summary, the sorting device disclosed by the present invention helps to solve the problems that the existing ore intelligent sorting system cannot monitor the working state in real time, must stop the machine when debugging the working parameters, any fault needs to be solved by stopping the machine for debugging, it is difficult to perform ore circulation operation during the process of debugging the working parameters, and professional technical personnel need to participate throughout the process.

[0037] The state monitoring and repair and debugging method of the sorting device disclosed by the present invention continuously judges the working state of the system by real-time monitoring of the signals returned by each sensor in the system, automatically switches to the circulation mode after identifying a fault, repeatedly adjusts adaptively, and automatically switches back to the normal operation mode after the repair is completed, realizing the rapid and continuous circulation of the ore during the process of debugging the working parameters of the sorting device. At the same time, most faults can be automatically detected and repaired, and the working parameters can be automatically debugged, solving the disadvantages that the traditional sorting system can only judge the system operation state and identify system faults by manual verification of the sorting results, and further solving the problems that all faults of the traditional sorting system need to be solved by stopping the machine for debugging and the on-site operation of the manufacturer's technical personnel is required, ensuring that the equipment is in a fault-free normal state at any moment during the operation process, and greatly improving the stability of the discharged material.

[0057] The present invention will be further described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0058] Embodiment 1

[0059] Figures 1 to 7 and Figure 9 Figure 9 shows an embodiment of the sorting device of the present invention. The sorting device of this embodiment includes a sorting conveyor track 1 and a circulating conveyor track 5. Along the conveying direction, the sorting conveyor track 1 is successively provided with a material leveling mechanism 2, a material size identification mechanism 6, an optoelectronic imaging mechanism 7, and a blowing mechanism 9. The discharging end of the sorting conveyor track 1 is docked with the feeding end of the circulating conveyor track 5, and the discharging end of the circulating conveyor track 5 is docked with the feeding end of the sorting conveyor track 1. A switching mechanism 8 for discharging or circulating the material is provided at the discharging end of the sorting conveyor track 1. Among them, the sorting conveyor track 1 and the circulating conveyor track 5 are preferably conveyor belts. Of course, in other embodiments, the sorting conveyor track 1 and the circulating conveyor track 5 can also be conveyor chain plates, etc.

[0060] In the normal working mode of the sorting device of this embodiment, the ore enters the material leveling mechanism 2 driven by the sorting conveyor track 1. On the one hand, it can make the ore enter the sorting process in a uniform and dispersed state, significantly improving the accuracy and stability of the material size identification mechanism 6, laying a foundation for subsequent precise sorting. On the other hand, considering the influence of the time interval limit between the two blowing operations of the blowing mechanism 9 on the sorting accuracy, this can also optimize the ore flow, realizing queuing feeding along the width direction of the sorting conveyor track 1, avoiding the delay of the blowing timing and the loss of accuracy of the subsequent blowing mechanism 9, ensuring that each round of blowing of the blowing mechanism 9 can accurately act on the target ore, improving the overall sorting efficiency, and at the same time avoiding the situation of overuse of some nozzles and non-use of some nozzles of the blowing mechanism 9, and improving the overall service life of the nozzles. When the relevant parameters of the sorting device need to be adjusted, that is, when the sorting device enters the debugging mode, the switching mechanism 8 acts, the circulating conveyor track 5 starts, and the ore no longer discharges but returns to the feeding end of the sorting conveyor track 1 through the circulating conveyor track 5 for circulation, which helps to solve the problems that the existing ore intelligent sorting system must stop during the debugging of working parameters, the ore circulation operation is difficult during the debugging of working parameters, and professional technicians need to participate throughout the process, etc. There is no need to manually transport the ore sorted out during the debugging process, and there is no need to stop the machine during the debugging process, greatly reducing the time, labor and other costs during the debugging process. At the same time, by ensuring the single variable principle during the debugging process, the debugging results are more accurate, and the debugging process is made more flexible, reducing the impact of the 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 device finishes debugging, the circulating conveyor track 5 can be quickly disassembled; when debugging is required again, the circulating conveyor track 5 can also be quickly installed, without additionally 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 size identification mechanism 6, the optoelectronic imaging mechanism 7, and the blowing mechanism 9).

[0061] Furthermore, in this embodiment, the switching mechanism 8 includes a baffle 81. 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. At least one first swing rod 82 or at least one second swing rod 83 is connected to a swing driving member (not shown in the figure, which can be a motor, etc.). When the sorting equipment is in the normal working mode, the baffle 81 can swing above the sorting conveyor track 1, and the ore can be discharged through the sorting conveyor 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 conveyor track 1 to block. Under the action of the first swing rod 82 and the second swing rod 83 at both ends, the movement of the baffle 81 is stable, and it can withstand the impact of the ore at the same time. The structure is simple and reliable.

[0062] Still further, 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 is docked with the feed end of the circulating conveyor track 5 through a first vibrating chute 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. The discharge end of the circulating conveyor track 5 is docked with the feed end of the sorting conveyor track 1 through a second vibrating chute 52. The circulating conveyor track 5 includes a horizontal conveyor track and a lifting conveyor track docked with the horizontal conveyor track. 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 conveyor track 1 to block. The ore drops onto the lower first vibrating chute 51 under the action of the baffle 81. The first vibrating chute 51 is activated to transfer the ore to the circulating conveyor track 5 (specifically, the horizontal conveyor track). The circulating conveyor track 5 (specifically, the lifting conveyor track) then transfers the ore to the second vibrating chute 52. The second vibrating chute 52 transfers the ore to the feed end of the sorting conveyor track 1 (specifically, the third vibrating chute 13). By vibration (such as an electric vibrator, etc.), the discharge speed of the ore can be increased, preventing blockage. The structure is simple and reliable.

[0063] Furthermore, for the sorting equipment of this embodiment, the sorting conveyor track 1 includes a first conveyor track 11 and a second conveyor track 12. The material leveling mechanism 2 includes a plurality of partition plates 21 spaced along the width direction of the first conveyor track 11. A material leveling channel 22 is formed between adjacent partition plates 21. The material leveling mechanism 2 is connected with a material leveling driving mechanism 3 to realize reciprocating movement along the width direction of the first conveyor track 11. 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 conveyor track 12.

[0064] Driven by the first conveying track 11, the ore enters the material leveling channel 22 between the middle partitions 21 of the material leveling mechanism 2. The material leveling driving mechanism 3 drives the material leveling mechanism 2 to reciprocate in 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 improving the accuracy and stability of the material size recognition mechanism 6, laying a foundation for subsequent precise sorting. On the other hand, considering the influence of the time interval limit between the two blowing operations of the blowing mechanism 9 on the sorting accuracy, this can also optimize the ore flow, realizing queuing feeding in the width direction of the first conveying track 11, avoiding the delay of the blowing timing and the loss of accuracy of the subsequent blowing mechanism 9, ensuring that each round of blowing of the blowing mechanism 9 can accurately act on the target ore, improving the overall sorting efficiency, and at the same time avoiding the situation of overuse of some nozzles and non-use of some nozzles of the blowing mechanism 9, and improving the overall service life of the nozzles.

[0065] See specifically Figure 12 , as a preferred embodiment, the material size recognition mechanism 6 includes a multi-line lidar. The three-dimensional point cloud data of the ore on the second conveying track 12 can be obtained by scanning the surface of the ore with the multi-line lidar, and then the minimum bounding box of a single ore is calculated to obtain the size of different ores, which helps to assist the blowing mechanism 9 to achieve precise blowing (ores of different sizes require different blowing forces. By identifying the size information of the ore, parameters such as the blowing duration and the number of blowing ports of the blowing mechanism 9 can be optimized), further improving the sorting efficiency. Of course, in other embodiments, other methods can also be used to realize the recognition of the ore size, such as the multi-view vision method, using cameras at different angles to reconstruct the three-dimensional point cloud of the ore, and then obtaining its size information.

[0066] As a preferred embodiment, the optoelectronic imaging mechanism 7 includes an X-ray transmission detector. Without damaging the material, the internal information of the material can be reflected by the attenuation information of the penetrated X-ray. The gray value of its imaging picture represents the absorption of the ore by the X-ray and is easily affected by the thickness of the ore. By decoupling the results obtained by the material size recognition mechanism 6 and the X-ray transmission image obtained by the optoelectronic imaging mechanism 7 at the pixel level, the gray value of each pixel affected by the thickness is corrected and compensated, so as to avoid the influence of the thickness and realize more accurate classification of the ore to judge whether it is waste rock. Finally, the blowing mechanism 9 realizes precise blowing according to the ore size information and the ore category, and the system structure is reasonable and effective.

[0067] Furthermore, in this embodiment, a third vibrating material guiding trough 8 is provided at one end of the first conveying track 11 away from the second conveying track 12. See specifically Figure 3, the third vibrating material guiding trough 13 is butted against the upper end of the first conveying track 11, and the second conveying track 12 is butted against the lower end of the first conveying track 11. Ore can be added into the third vibrating material guiding trough 8 and then enter the storage bin 4 under the action of gravity. The structure is simple and reliable.

[0068] For details, refer to Figure 9 , further, in this embodiment, the material leveling mechanism 2 further includes an upper cover plate 23. The upper sides of the partition plates 21 are connected to the upper cover plate 23. The upper cover plate 23 is hinged with a limiting plate 24 at the inlet end of each material leveling channel 22. An elastic member 25 (such as a spiral spring, elastic rubber, etc.) is provided between the limiting plate 24 and the upper cover plate 23. A limiting member 241 (such as a limiting rod, limiting block, etc.) for restricting the rotation angle is provided on the lower side of the limiting plate 24. The limiting member 241 performs motion constraint on the limiting plate 24 to restrict its downward rotation range. The lowest height of the limiting plate 24 is the maximum size of the incoming ore. When the ore is too much in a certain material leveling channel 22 and squeezes the limiting plate 24 up and down, the elastic member 25 can increase the height dimension of the material leveling channel 22. While limiting the height of the incoming material, it speeds up the passing speed of the ore, realizing the normal feeding of the ore. The structure is reasonable and effective.

[0069] Further, in this embodiment, the material leveling driving mechanism 3 includes a rotary driving member 31, a turntable 32, a connecting rod 33, a guide rail 34, and a sliding seat 35 provided on the guide rail 34. The turntable 32 is connected to the rotary driving member 31. One end of the connecting rod 33 is hinged to the turntable 32 and the hinged position deviates from the center of the turntable 32. The other end of the connecting rod 33 is hinged to the sliding seat 35. The upper cover plate 23 is connected to the sliding seat 35. During operation, the rotary driving member 31 drives the turntable 32 to rotate. Since the hinged position of the connecting rod 33 and the turntable 32 deviates from the center of the turntable 32, when the turntable 32 rotates, it can drive the sliding seat 35 to reciprocate along the guide rail 34 through the connecting rod 33. The guide rail 34 provides a guiding function for the sliding seat 35 to ensure the smooth and stable movement process and avoid deviation. The sliding seat 35 drives the upper cover plate 23 and the connected partition plates 21 to reciprocate along the width direction of the first conveying track 11, thereby optimizing the ore flow and enabling the ore to enter the subsequent sorting process in a uniform and dispersed state. Preferably, two guide rails 34 are provided in total, which can further strengthen the guiding effect.

[0070] As a preferred embodiment, the rotary driving member 31 is a speed-regulating motor, and a speed reducer 36 is provided between the speed-regulating motor and the turntable 32. The speed-regulating motor serves as a power source, and the speed-regulating motor and the speed reducer 36 together ensure the speed-changing requirements, and can conveniently control the movement speed of the partition plate 21.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] Embodiment 2

[0076] 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 Embodiment 1, except that:

[0077] In this embodiment, a swing plate 211 is hinged at the outlet end of the material leveling channel 22 of the partition plate 21. The upper sides of the swing plates 211 are connected by a connecting plate 26, and the material leveling driving mechanism 3 is connected to the connecting plate 26. That is, in this embodiment, the partition plate 21 no longer reciprocates, but the material leveling driving mechanism 3 drives each swing plate 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 leveling 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.

[0078] Furthermore, in this embodiment, three connecting columns 261 are arranged on the connecting plate 26 along the length direction. The material leveling driving mechanism 3 includes a rotary driving member 31, a turntable 32, a connecting rod 33, a guide rail 34 and three sliding seats 35 arranged on the guide rail 34. An arc-shaped guide groove 351 is provided on the sliding seat 35, and the three connecting columns 261 are respectively inserted into the three arc-shaped guide grooves 351. The turntable 32 is connected to the rotary driving member 31. One end of the connecting rod 33 is hinged to the turntable 32 and the hinged part deviates from the center of the turntable 32. The connecting column 261 located at the center is inserted into the other end of the connecting rod 33. During operation, the rotary driving member 31 drives the turntable 32 to rotate. Since the hinged part of the connecting rod 33 and the turntable 32 deviates from the center of the turntable 32, the turntable 32 can drive the connecting column 261 located at the center to move through the connecting rod 33 when rotating. The connecting plate 26 and the connecting columns 261 on both sides move with the connecting column 261 located at the center, and then drive each swing plate 211 below the connecting plate 26 to swing back and forth along the width direction of the first conveying track 1. The sliding seat 35 reciprocates along the guide rail 34 under the drive of the connecting column 261. The guide rail 34 provides a guiding function for the sliding seat 35 to ensure that the moving process is stable and smooth and avoid deviation. The arc-shaped guide groove 351 on the sliding seat 35 provides a guiding function for the connecting column 261, so as to optimize the flow of the ore, so that the ore enters the subsequent sorting process in a uniform and dispersed state, and the structure is reasonable and effective.

[0079] Specifically refer to Figure 10 , furthermore, in this embodiment, rolling elements 352 (such as ball bearings) are arranged around the arc-shaped guide groove 351, which can reduce the frictional resistance and wear between the arc-shaped guide groove 351 and the connecting column 261, and the structure is simple and reliable.

[0080] Embodiment 3

[0081] Figure 11Another embodiment of the sorting device of the present invention is shown. The sorting device of this embodiment is basically the same as those in the first and second embodiments, except that:

[0082] In this embodiment, there are two connecting plates 26 provided downstream of the partition plate 21. Multiple stirring rods 262 are provided on the connecting plates 26. Preferably, the multiple stirring rods 262 are arranged in a staggered manner (or non-collinear) along the movement direction of the conveyor belt, which is beneficial to strengthening the material leveling effect. The material leveling driving mechanism 3 includes a rotary driving member 31, a bent rod 321, two connecting rods 33, two guide rails 34, and a sliding seat 35 provided on the guide rails 34. The bent rod 321 is connected to the rotary driving member 31. One end of each connecting rod 33 is hinged to the bent rod 321, and the other end of each connecting rod 33 is correspondingly hinged to each sliding seat 35. Each connecting plate 26 is correspondingly connected to each sliding seat 35. The moving directions of two adjacent connecting plates 26 are opposite. During operation, the rotary driving member 31 drives the bent rod 321 to rotate. Since the connecting rod 33 is hinged to the bent rod 321, when the bent rod 321 rotates, it can drive the sliding seat 35 to reciprocate along the guide rail 34 through the connecting rod 33, and the movements 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, and avoid deviation. The sliding seat 35 drives the connecting plate 26 and the stirring rods 262 connected thereto to reciprocate along the width direction of the first conveying track 11, so as to optimize the ore flow and make the ore enter the subsequent sorting process in a uniform and dispersed state. Since the moving directions of two adjacent connecting plates 26 are opposite, and they cooperate with each other, the material leveling effect can be further strengthened. Of course, in other embodiments, the number of the connecting plates 26 can also be adjusted (the connecting rod 33, the guide rail 34, and the sliding seat 35 can be adjusted accordingly).

[0083] Embodiment 4

[0084] As Figure 13 shown, the state monitoring and repair debugging method of the sorting device of this embodiment includes the following steps:

[0085] S100, judging whether there is a fault according to the working condition parameter information of the sorting device in the working mode and the warning information of the sorting device;

[0086] S200, if there is a fault in the sorting device, further judging the type of the fault, and executing one of the following steps according to the type of the fault:

[0087] S201. If the fault type is a first - type fault, repair the corresponding fault in a shutdown and maintenance manner (such as mechanical mechanism damage, circuit damage, etc., faults that must be repaired by shutdown and maintenance). After the fault is repaired, switch the mechanism 8 to actuate, start the circulating conveyor track 5, and the sorting equipment enters the debugging mode, enabling the ore to be sorted to re - enter the sorting conveyor track 1 through the circulating conveyor track 5. In the debugging mode, determine whether the fault is resolved, and after the fault is resolved, reset the mechanism 8, stop the circulating conveyor track 5, and the sorting equipment re - enters the working mode;

[0088] S202. If the fault type is a second - type fault, switch the mechanism 8 to actuate, start the circulating conveyor track 5, and the sorting equipment enters the debugging mode to repair the corresponding fault in a non - shutdown and maintenance manner. In the debugging mode, determine whether the fault is resolved, and after the fault is resolved, reset the mechanism 8, stop the circulating conveyor track 5, and the sorting equipment re - enters the working mode. If the fault cannot be resolved, convert the fault type to a first - type fault and execute step S201;

[0089] Among them, the first - type faults include hardware faults indicating mechanical structure damage or circuit damage in the working condition parameter information or system warning information; the second - type faults include software faults indicating algorithm faults or incorrect working parameter settings in the working condition parameter information or system warning information.

[0090] In this embodiment, in steps S201 and S202, determining whether the fault is resolved includes:

[0091] Add a standard ore sample that is artificially synthesized, with all known ore properties and marked, to the sorting equipment. If the difference between the actual rejection rate and the target rejection rate of the standard ore sample is within the preset range, it means the fault has been resolved; otherwise, it means the fault has not been resolved. When the difference between the actual rejection rate and the target rejection rate is too large, or the equipment determines that the existing working condition parameters are insufficient to achieve the target rejection rate, start the debugging mode and automatically adjust the equipment working parameters such as the tube voltage and tube current of the photoelectric imaging mechanism 7 and the transportation speed of the sorting conveyor track 5 until the actual rejection rate meets the standard. Among them, the actual rejection rate is a value comprehensively obtained through methods such as monitoring ore flow, volume evaluation, and gray - scale calculation. At the same time, the equipment's judgment on whether the existing working condition parameters can achieve the target rejection rate is also based on these data. The target rejection rate is formulated according to the production plan.

[0092] In this embodiment,

[0093] If the fault still exists, determine the type of the fault, and correspondingly execute step S201 or step S202 according to whether the fault is a first - type fault or a second - type fault to repair the fault. Repeat the execution until the fault has been resolved, then reset the mechanism 8, stop the circulating conveyor track 5, and the sorting equipment re - enters the working mode.

[0094] In this embodiment,

[0095] 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 ore to be sorted deduced based on the working parameters set for the sorting equipment, the actual number of discarded ore deduced by collecting images through the camera at the blowing mechanism 9, and the brightness information of the sorting and conveying track 1 for conveying the ore flow in the sorting equipment under the photoelectric imaging mechanism 7;

[0096] The warning information includes one or more of the jamming of the sorting and conveying track 1, the insufficient air tank pressure of the blowing mechanism 9, the jet delay of the blowing port of the blowing mechanism 9, and the nozzle blockage.

[0097] The state monitoring and repair debugging method disclosed in this embodiment realizes the rapid and uninterrupted circulation of ore during the debugging of the working parameters of the sorting equipment by continuously monitoring the signals returned by each sensor in the equipment, continuously judging the working state of the equipment, automatically switching to the loop mode after identifying a fault, repeatedly adjusting adaptively, and automatically switching back to the normal working mode after the repair is completed. At the same time, it can automatically detect and repair most faults, and automatically debug the working parameters, solving the drawbacks that the traditional sorting system can only judge the system operation state and identify system faults by manual verification of the sorting results, and further solving the problem that all faults of the traditional sorting system need to be repaired by stopping the machine for debugging and require on-site operation by the manufacturer's technical personnel, ensuring that the equipment is in a fault-free normal state at any moment during the operation process, and greatly improving the stability of the discharged material.

[0098] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. 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 shall fall within the scope of the protection of the technical solution of the present invention.
