Description

Technical Field

[0001] This application relates to the field of ore sorting equipment, and more particularly to a conveying device for ore sorting that prevents deviation. Background Technology

[0002] The intelligent dry sorting system sorts materials based on their density. Materials of different densities appear in different colors under the intelligent recognition source, and the sorting execution mechanism sorts them according to the different colors of the material images.

[0003] The sorting system mainly includes a material conveying system, an imaging and image analysis system, a computer control system, and a material separation execution system. During sorting, the analysis system extracts and identifies useful minerals and impurities based on the features of the imaging, as well as the virtual material channels in which they are located. The control system calculates the time it takes for various materials to reach the designated position, and controls the execution structure to complete the sorting action within the corresponding virtual material channel.

[0004] Conveyor system misalignment is a common fault in sorting machines. When the conveyor system misaligns, it causes a deviation between the channel where the control system marks the material and the actual channel where the material is located. This prevents the actuators from sorting the marked material, reducing sorting efficiency and quality. Therefore, existing conveyor systems typically include anti-misalignment devices. However, to ensure sufficient analysis and execution time, the imaged position of the material and the position of the actuators do not coincide. When the anti-misalignment device corrects the conveyor belt, it may actually change the position of the marked material, affecting sorting quality.

[0005] Secondly, in order to ensure that the analysis system can accurately identify useful minerals and impurities, a vibrating feeding device is used to spread the feed evenly on the surface of the conveyor belt. However, the setting of the execution structure is usually discontinuous. In particular, when the execution structure blows air into the corresponding virtual material channel to mark the minerals, some minerals will be located at the edge of the nozzle's range of action and cannot be blown to the target outlet, thus reducing the quality of sorting. Summary of the Invention

[0006] This application proposes a conveying device for preventing deviation in ore sorting, which can limit deviation of ore after leaving the imaging and analysis system, ensuring the reliability of the sorting execution structure and improving sorting efficiency.

[0007] To achieve the above objectives, this application adopts the following technical solution: a conveying device for preventing deviation in ore sorting, comprising a shell, a conveyor belt inside the shell, the conveyor belt having an automatic deviation correction device, an imaging and analysis system in the middle of the shell, the imaging and analysis system generating an image of the illumination range, transmitting the image to the analysis system, identifying and recording the virtual material channel where useful ore or impurities are located and the distance from the tail of the conveyor belt, and transmitting the data to the control system, the tail of the conveyor belt having a sorting execution structure;

[0008] A ore gathering structure is provided between the imaging and analysis system and the tail of the conveyor belt. The ore gathering structure includes multiple sets of inner and outer connecting rods continuously distributed along the conveying direction. Each set of inner and outer connecting rods is provided with multiple sets of first and second gathering plates. Each set of first and second gathering plates corresponds one-to-one with the virtual material channel. The side wall of the housing is provided with a pusher that can adjust the axial position of the inner and outer connecting rods. The inner and outer connecting rods are connected to a transmission chain. The transmission chain drives the first and second gathering plates to move to the end of the conveyor belt along the conveying direction, and the moving speed is the same as that of the conveyor belt.

[0009] Furthermore, the connecting shaft, outer connecting rod, and inner connecting rod are coaxial, and the outer connecting rod, inner connecting rod, and connecting shaft are sequentially sleeved together. The bottom of the outer connecting rod is provided with a notch groove for the inner connecting rod to connect with the first gathering plate and for the connection point to slide.

[0010] Furthermore, the pushing component includes a gathering pushing component, an adjusting pushing component, and a resetting pushing component. The adjusting pushing component can drive the outer connecting rod and the inner connecting rod to move axially, adjusting the position of the first gathering plate and the second gathering plate when they contact the conveyor belt. The gathering pushing component drives the outer connecting rod and the inner connecting rod to move towards each other, so that the first gathering plate and the second gathering plate move closer to each other to gather the ore. The resetting pushing component drives the outer connecting rod and the inner connecting rod to move away from each other and reset.

[0011] Furthermore, the pushing component includes two sets of base plates disposed on both sides of the housing. The base plates are provided with telescopic rods. The telescopic rods contact the first gathering plate and the second gathering plate from both sides respectively, thereby driving the inner connecting rod and the outer connecting rod to move towards each other.

[0012] Furthermore, the transmission chain forms a rectangle and has vertical and horizontal running sections.

[0013] Furthermore, friction structures for restricting the movement of the inner or outer connecting rod are provided between the connecting shaft and the inner connecting rod, and between the connecting shaft and the outer connecting rod. The friction structure includes a pressure rod and a control bladder inside the connecting shaft, and a resistance bladder on the outer wall of the connecting shaft. The resistance bladder and the control bladder are connected. A spring is provided between the pressure rod and the connecting shaft. Under the action of the spring, the connecting shaft squeezes the control bladder, causing the resistance bladder to expand. When the pressure rod is pressed, the pressure rod no longer squeezes the control bladder, and the resistance bladder contracts. The pusher is provided with an inclined surface. When the connecting shaft moves to the inclined surface, the inclined surface presses against the pressure rod.

[0014] Furthermore, the control steps for the aggregated structure of the ore include:

[0015] S1: Establish a coordinate system (X, Y), where X represents the time required for the region to reach the execution structure, and Y represents the position of the region relative to the conveyor belt axis. Obtain the coordinate range of each virtual material channel {(X... i Y m )|t m <X m <t m+1 , l i <Y i <l i+1}, l i Indicates material channel L i The initial boundary coordinates, m represents the work cycle number of the sorting execution structure when reaching the sorting execution structure, and t represents the starting boundary coordinates. m This indicates the start time of the execution structure's work in period m;

[0016] S2: Obtain the data information output by the imaging and analysis system (3), obtain the coordinate information of the effective ore or waste, and extract and mark the coordinates (X) of the ore A. A Y A ), determine (X) A Y A Does it belong to {(X)}? i Y m )|t m <X m <t m+1 , l i <Y i <l i+1} Determine and record the material channel Li to which the marked ore belongs and the corresponding sorting cycle;

[0017] S3: Analyze the data within the same period m, and statistically analyze the data for each virtual material channel L. i Given the quantity of marked ore A (Q1) and the total amount of ore (Q2), determine if the ratio of Q1 to Q2 is greater than V, and count the total number N of virtual material channels with a ratio greater than V. ms The total number Q of marked ore A ms N ms Q represents the number of material channels that need to be sorted after S offsets within m periods. ms This represents the sum of the number of marked ore A in the material channel that needs to be sorted after offset S times within m periods;

[0018] S4: Offset the virtual feed channel by c to obtain the new virtual feed channel coordinate range {(X i Y m )|t m <X m <t m+1 ,

[0019] l i +c <Y i <li+1 +c};

[0020] S5: Repeat steps S2-S4 to obtain and record N sequentially. ms and Q ms N ms Q represents the number of material channels that need to be sorted after S offsets within m periods. ms This represents the sum of the number of marked ore A in the material channel that needs to be sorted after offset S times within m periods;

[0021] S6: Comparison yields Q ms Find the maximum value and record the offset R corresponding to the maximum value. m =S m *c, S m This represents the number of offsets corresponding to achieving the maximum sorting volume within m cycles;

[0022] If Q ms If multiple values ​​are identical, then compare the N corresponding to the virtual material channel. ms Find the minimum value and record the offset R corresponding to the minimum value. m =S m *c, S m This represents the number of offsets required to achieve the maximum sorting volume and use the fewest sorting channels within m cycles.

[0023] If N ms If multiple values ​​are still the same, then S m Take the corresponding minimum value;

[0024] S7: The control system pre-calculates the motion cycle m, the time of arrival at the adjusting pusher (48), and the time of arrival at the gathering pusher (47) for each group of first gathering plates (45) and second gathering plates (46). When the group of first gathering plates (45) and second gathering plates (46) arrives at the adjusting pusher (48), the adjusting pusher (48) drives the first gathering plates (45) and second gathering plates (46) to deviate by R. m ;

[0025] S8: When the first gathering plate (45) and the second gathering plate (46) pass the gathering pusher (47), the first gathering plate (45) and the second gathering plate (46) return to the initial feed channel.

[0026] Furthermore, in step S6, the frequency of each offset occurrence within the maintenance cycle is counted and the frequency P is calculated. s Calculate p s The difference between p and p is such that when the difference is greater than the warning value p0, the control system sends a warning and a potential offset R to the terminal.

[0027] Furthermore, R mThe maximum value is half the width of the virtual feed channel.

[0028] The beneficial effects of this invention are:

[0029] This application provides a conveying device for preventing deviation in ore sorting. By using a first gathering plate and a second gathering plate to constrain the axial movement of the ore, the axial position of the ore exiting the imaging and analysis system no longer changes. This allows the sorting execution structure to accurately sort out the marked ore, ensuring sorting efficiency. On the other hand, the movement of the first gathering plate and the second gathering plate towards each other causes the ore to gather towards the center of the material channel, improving the reliability of the sorting execution structure during sorting.

[0030] By temporarily adjusting the virtual material channels, effective minerals and waste materials are further enriched within their respective virtual channels, reducing the workload of the sorting execution structure while improving sorting efficiency. Attached Figure Description

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] Example 1

[0049] Please see Figure 2-3 A conveyor device for preventing deviation in ore sorting is provided. Based on an existing conveyor belt with deviation correction function, it includes a housing 1, a conveyor belt 2 inside the housing 1, and an imaging and analysis system 3 in the middle of the housing 1. The imaging and analysis system 3 consists of a top X-ray emitter and a receiver at the bottom of the conveyor belt 2. The imaging and analysis system 3 generates an image of the irradiation range and transmits the image to the analysis system. It identifies and records the virtual material channel where useful ore or impurities are located and the distance from the tail of the conveyor belt 2, and transmits the data to the control system. The tail of the conveyor belt 2 is provided with a sorting execution structure 5. The sorting execution structure 5 sorts out the ore in the designated material channel at a specified time according to the instructions of the control system.

[0050] A ore accumulation structure 4 is provided between the imaging and analysis system 3 and the tail end of the conveyor belt 2. Please refer to [link / reference]. Figure 1 , Figure 4 and Figure 5The ore gathering structure 4 includes multiple sets of inner connecting rods 44 and outer connecting rods 43 continuously distributed along the conveying direction. Each set of inner connecting rods 44 and outer connecting rods 43 is equipped with multiple sets of first gathering plates 45 and second gathering plates 46. Each set of first gathering plates 45 and second gathering plates 46 corresponds one-to-one with the virtual material channel. The width of the first gathering plates 45 and second gathering plates 46 is the same as the width of the marking area of ​​the analysis system. The side wall of the housing 1 is provided with a pusher that can drive the inner connecting rods 44 and outer connecting rods 43 to move towards each other, so that the inner connecting rods 44 and outer connecting rods 43 move towards the center of the corresponding virtual material channel, that is, gather the material into the strong action range of the sorting execution structure 5, reducing Mineral material at the edge of the sorting execution structure 5's operating range is scattered during sorting. The inner connecting rod 44 and the outer connecting rod 43 are connected to a transmission chain 41 via a connecting shaft 42. The transmission chain 41 drives the first gathering plate 45 and the second gathering plate 46 to move along the conveying direction to the end of the conveyor belt 2, and the moving speed is the same as that of the conveyor belt. The material constrained by the first gathering plate 45 and the second gathering plate 46 is no longer affected by the deviation of the conveyor belt 2 or the correction of the conveyor belt 2, and its position relative to the virtual material channel does not change. At the same time, the first gathering plate 45 and the second gathering plate 46 move in the same direction as the conveyor belt, ensuring the moving speed of the mineral material, improving the sorting accuracy of the sorting execution structure 5, and improving the sorting quality.

[0051] Please see Figure 6 and Figure 7 The connecting shaft 42, the outer connecting rod 43, and the inner connecting rod 44 are coaxial. The outer connecting rod 43, the inner connecting rod 44, and the connecting shaft 42 are sequentially sleeved. The bottom of the outer connecting rod 43 is provided with a notch groove for the inner connecting rod 44 to connect with the first gathering plate 45 and for the connection point to slide. The same connecting shaft 42 drives the inner connecting rod 44 and the outer connecting rod 43 in the same group to move, making the structure simpler.

[0052] Please see Figure 4 and Figure 5 The pushing components include a gathering pushing component 47, an adjusting pushing component 48, and a resetting pushing component 49. The adjusting pushing component 48 can drive the outer connecting rod 43 and the inner connecting rod 44 to move axially, adjusting the position of the first gathering plate 45 and the second gathering plate 46 when they contact the conveyor belt 2. The gathering pushing component 47 drives the outer connecting rod 43 and the inner connecting rod 44 to move towards each other, so that the first gathering plate 45 and the second gathering plate 46 move closer to each other to gather the ore. The resetting pushing component 49 drives the outer connecting rod 43 and the inner connecting rod 44 to move away from each other and reset, which facilitates the positioning of the adjusting pushing component 48.

[0053] Please see Figures 9-11The gathering pusher 47 includes two sets of base plates 471 disposed on both sides of the housing 1. The base plate 471 is provided with a telescopic rod 473. The telescopic rod 473 presses against the first gathering plate 45 and the second gathering plate 46 from both sides, thereby driving the inner connecting rod 44 and the outer connecting rod 43 to move towards each other. The structure of the adjusting pusher 48 and the resetting pusher 49 is similar to that of the gathering pusher 47, and will not be described in detail. The difference is that the piston rod of the cylinder of the adjusting pusher 48 is provided with a groove that can just lock the first gathering plate 45 or the second gathering plate 46, which can drive the inner connecting rod 44 and the outer connecting rod 43 to move arbitrarily. The piston rod of the resetting pusher 49 is provided with a crossbar, which can hook the first gathering plate 45 and the second gathering plate 46 from the side to reset.

[0054] Please see Figure 5 The transmission chain 41 forms a rectangle with vertical and horizontal running sections, which facilitates the adjustment of the position of the pushing component.

[0055] Please see Figure 8 Friction structures are provided between the connecting shaft 42 and the inner connecting rod 44, and between the connecting shaft 42 and the outer connecting rod 43, to limit the movement of the inner connecting rod 44 or the outer connecting rod 43. The friction structures include a pressure rod 410 and a control bladder 412 located inside the connecting shaft 42, and a resistance bladder 411 located on the outer wall of the connecting shaft 42. The resistance bladder 411 and the control bladder 412 are connected. A spring 413 is provided between the pressure rod 410 and the connecting shaft 42. Under the action of the spring 413, the connecting shaft 42 compresses the control bladder 412, causing the resistance bladder 411 to expand, thus achieving the function of friction limiting. When the pressure rod 410 is pressed, it no longer compresses the control bladder 412, and the resistance bladder 411 contracts. Figure 8 The relationship between the friction structure and the outer connecting rod 43 is shown in the diagram. The relationship between the other end and the inner connecting rod 44 is the same and will not be shown again. The pusher has an inclined surface. When the connecting shaft 42 moves to the inclined surface, the inclined surface presses down on the pressing rod 410, so that the outer connecting rod 43 and the inner connecting rod 44 are in a movable state. See the appendix for details on the inclined surface. Figure 9 Medium bevel 472.

[0056] Please see Figure 2 The second gathering plate 46 includes a connecting plate 461 fixedly connected to the outer connecting rod 43. The connecting plate 461 is connected to the elastic body 462 through the plate body 463. The two sides of the plate body 463 have flanges that restrict the axial movement of the elastic body 462. The elastic body 462 can stretch and contract appropriately to ensure that the second gathering plate 46 can contact the conveyor belt 2 with appropriate pressure. The structure of the first gathering plate 45 is similar to that of the second gathering plate 46, and will not be described in detail.

[0057] After the ore passes through the sorting execution structure 5, the second gathering plate 46 and the first gathering plate 45 clamp the ore and move synchronously with the conveyor belt 2, constraining the ore so that it will not deviate when the conveyor belt 2 is off-track or when correcting the deviation of the conveyor belt 2, ensuring that it moves within the designated ore channel, and ensuring the effective ore selection efficiency of the sorting. At the same time, the second gathering plate 46 and the first gathering plate 45 move towards each other, causing the ore to gather towards the middle of the channel, so that the sorted ore is concentrated in the optimal sorting area of ​​the sorting execution structure 5, improving the reliability of sorting.

[0058] Example 2, based on Example 1:

[0059] The control steps for mineral aggregate structure 4 include:

[0060] S1: Establish a coordinate system (X, Y), where X represents the time required for the region to reach the execution structure, and Y represents the position of the region relative to the axial direction of the conveyor belt (2). Obtain the coordinate range of each virtual channel {(X i Y m )|t m <X m <t m+1 , l i <Y i <l i+1}, l i Indicates material channel L i The initial boundary coordinates, m represents the work cycle number of the sorting execution structure (5) when reaching the sorting execution structure (5), and t represents the starting boundary coordinates. m This indicates the start time of the execution structure's work in period m;

[0061] S2: Obtain the data information output by the imaging and analysis system (3), obtain the coordinate information of the effective ore or waste, and extract and mark the coordinates (X) of the ore A. A Y A ), determine (X) A Y A Does it belong to {(X)}? i Y m )|t m <X m <t m+1 , l i <Y i <l i+1} Determine and record the material channel Li to which the marked ore belongs and the corresponding sorting cycle;

[0062] S3: Analyze the data within the same period m, and statistically analyze the data for each virtual material channel L. i Given the quantity of marked ore A (Q1) and the total amount of ore (Q2), determine if the ratio of Q1 to Q2 is greater than V, and count the total number N of virtual material channels with a ratio greater than V. msThe total number Q of marked ore A ms N ms Q represents the number of material channels that need to be sorted after S offsets within m periods. ms This represents the sum of the number of marked ore A in the material channel that needs to be sorted after offset S times within m periods;

[0063] S4: Offset the virtual feed channel by c to obtain the new virtual feed channel coordinate range {(X i Y m )|t m <X m <t m+1 ,

[0064] l i +c <Y i <l i+1 +c};

[0065] S5: Repeat steps S2-S4 to obtain and record N sequentially. ms and Q ms N ms Q represents the number of material channels that need to be sorted after S offsets within m periods. ms This represents the sum of the number of marked ore A in the material channel that needs to be sorted after offset S times within m periods;

[0066] S6: Comparison yields Q ms Find the maximum value and record the offset R corresponding to the maximum value. m =S m *c, S m This represents the number of offsets corresponding to achieving the maximum sorting volume within m cycles;

[0067] If Q ms If multiple values ​​are identical, then compare the N corresponding to the virtual material channel. ms Find the minimum value and record the offset R corresponding to the minimum value. m =S m *c, S m This represents the number of offsets required to achieve the maximum sorting volume and use the fewest sorting channels within m cycles.

[0068] If N ms If multiple values ​​are still the same, then S m Take the corresponding minimum value;

[0069] S7: The control system pre-calculates the motion cycle m, the time of arrival at the adjusting pusher (48), and the time of arrival at the gathering pusher (47) for each group of first gathering plates (45) and second gathering plates (46). When the group of first gathering plates (45) and second gathering plates (46) arrives at the adjusting pusher (48), the adjusting pusher (48) drives the first gathering plates (45) and second gathering plates (46) to deviate by R. m ;

[0070] S8: When the first gathering plate (45) and the second gathering plate (46) pass the gathering pusher (47), the first gathering plate (45) and the second gathering plate (46) return to the initial feed channel.

[0071] In step S6, the frequency of each offset occurrence within the maintenance cycle is counted and the frequency P is calculated. s Calculate p s The difference between p and the warning value p0 is used to send a warning and a potential deviation R to the terminal when the difference is greater than the warning value p0. The warning value P0 is the reciprocal of the maximum number of deviations. When a certain deviation occurs too many times, it indicates that the ore is prone to deviating to a certain position, indicating that there are other reasons for material deviation. It can identify material deviation caused by reasons other than conveyor belt deviation.

[0072] R m The maximum value is half the width of the virtual feed channel.
