Description

Technical Field

[0001] This invention relates to the field of coal mining and intelligent sorting technology, specifically to an intelligent coal sorting device and its usage method. Background Technology

[0002] After coal mining, raw coal is usually mixed with coal lumps of different qualities and particle sizes, as well as impurities such as gangue. In order to improve the value and utilization rate of coal products, raw coal needs to be sorted and classified.

[0003] Currently, there are various coal sorting equipment on the market, such as jigs and heavy media separators. These devices are mainly used to separate coal from gangue and have achieved good results in macroscopic quality sorting. However, for coal materials that have already undergone preliminary crushing and have a wide particle size range, further fine classification according to particle size is still a key link to improve the added value of products. Existing classification methods mostly use multi-layer vibrating screens to classify coal through screens with different aperture sizes.

[0004] However, this traditional classification method has obvious drawbacks: First, the screening process is mechanical and simplistic, and cannot be linked with an intelligent identification system. It cannot achieve rapid and accurate sorting and conveying of coal within a specific particle size range. Second, and more importantly, after sorting, coal of different particle sizes is usually transported to different fixed containers for temporary storage. When a container is full, the entire classification line needs to be stopped, and empty containers need to be replaced manually. This process is not only labor-intensive and inefficient, but also leads to production interruption, seriously affecting the continuous operation capability and automation level of the entire classification system.

[0005] Within the industry, intelligent sensing technologies such as image recognition and X-rays have begun to be introduced into coal sorting. However, existing technical solutions mostly focus on "recognition" itself and fail to integrate the recognition results with downstream material transportation, container management, and other processes to form an efficient and closed-loop intelligent system. In particular, there is a lack of effective intelligent solutions for the automatic replacement and transfer of containers, resulting in a disconnect between "recognition" and "execution" and making it impossible to truly achieve unmanned and intelligent operation throughout the entire process.

[0006] Therefore, there is an urgent need for an intelligent coal mine classification device and method that integrates intelligent identification, rapid classification and automatic box changing to solve the problems of inflexible classification, low box changing efficiency and poor production continuity in the existing technology. Summary of the Invention

[0007] The purpose of this invention is to provide a coal mine intelligent sorting device and its usage method, which has the advantages of full-process intelligence, accurate and efficient sorting, and continuous unmanned operation, thus solving the problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A coal mine intelligent sorting device includes a base plate, four first supports fixed to the upper part of the base plate, U-shaped blocks fixed to the upper parts of two first supports on the same side, a separation plate fixedly installed on the inner wall of the two U-shaped blocks, a movable frame placed on the upper part of the separation plate, a first pushing component disposed on the two U-shaped blocks for pushing the movable frame to move, a rebound component fixed to the upper part of the separation plate, a first camera component fixed to the upper part of one of the U-shaped blocks, a trough extending through the lower part of the separation plate, a first screening plate fixed to the inner wall of the trough, a solid plate fixed to the end of the first screening plate away from the first pushing component, and a solid plate fixed to the end of the solid plate away from the first pushing component. The components include: a second screening plate at one end of the moving assembly; a third support fixed to the upper end of the two U-shaped blocks; a belt conveyor fixed to the third support; a support block fixed to the upper end of the two U-shaped blocks; a second receiving hopper fixed to the two support blocks for receiving the conveyor belt from the coal mine; a second support fixed to the upper end of the base plate; a first bearing plate fixed to the upper end of the second support; a first collecting trolley set on the upper end of the first bearing plate; a second pushing assembly set on the upper end of the first bearing plate for moving the first collecting trolley; a second bearing plate fixed to the upper end of the base plate; a second collecting trolley and a third pushing assembly set on the upper end of the second bearing plate. The second receiving hopper is equipped with a feeding component. The second collecting trolley and the first collecting trolley have the same structure. The third pushing component and the second pushing component have the same structure. The upper part of the base plate is provided with a frame, and a first receiving hopper is fixedly connected to the frame. The feeding end of the first receiving hopper corresponds to the discharging end of the second screening plate. The upper part of the base plate is equipped with a second camera component for observing the second collection trolley, and the upper part of the base plate is equipped with a control component. The discharge end of the second hopper corresponds to the upper part of the first screening plate. The first bearing plate is provided with a first weighing platform for weighing the first collection trolley, and the second bearing plate is provided with a second weighing platform for weighing the second collection trolley.

[0009] Preferably, the first pushing assembly includes a first fixed seat fixed between two U-shaped blocks, a first cylinder fixed to the end of the first fixed seat away from the movable frame, and a first push block fixed to the output shaft of the first cylinder, wherein the ends of the first push block and the movable frame that are close to each other are fixedly connected to each other.

[0010] It is worth noting that the first pushing component is driven by a cylinder, which can precisely control the movement stroke and speed of the movable frame, avoid human operation errors, ensure the accurate movement position of the coal on the separation plate, and provide a basis for subsequent classification.

[0011] Preferably, the rebound assembly includes a first fixing block fixed to the upper end of the separation plate, at least two springs fixed to the first fixing block near one end of the movable frame, and a movable block fixed to the at least two springs near one end of the movable frame.

[0012] It is worth noting that the rebound component provides a stable rebound force through at least two springs. After the movable frame is pushed by the first push component, it can drive the movable frame to quickly reset without the need for additional drive components, thus saving energy. The setting of at least two springs can ensure that the movable block is evenly stressed, avoiding offset or jamming when the movable frame resets, and preventing the sorting process from being affected by reset problems.

[0013] Preferably, the first camera assembly includes a first stand fixed to the upper end of the U-shaped block and a first camera fixed to the lower end of the first stand, and the second camera assembly includes a second stand fixed to the upper end of the base plate and a second camera fixed to the second stand.

[0014] It is worth noting that: the first camera can collect image information of the coal mine on the separation plate in real time, providing visual data support for the initial identification and classification of the coal mine; the second camera can observe the material accumulation and position status of the second collection trolley in real time, providing a basis for subsequent control; the second stand can stably fix the camera, ensuring that the shooting angle and position are fixed, avoiding camera shaking that causes image blurring or inaccurate observation, providing reliable data for the intelligent control of the control components, and significantly improving the intelligence level of the device.

[0015] Preferably, two baffles are fixed to the upper end of the U-shaped block. The ends of the two baffles that are close to each other are attached to both sides of the conveyor belt of the belt conveyor. Guide blocks are fixed to the ends of the two baffles that are close to each other. The downward surfaces of the two guide blocks form a figure-eight shape. Two second limiting blocks for limiting the second collecting trolley are fixed to the upper end of the second bearing plate. Two first limiting blocks are fixed to the upper end of the first bearing plate. The ends of the two first limiting blocks that are close to each other are respectively attached to the ends of the two corresponding rollers that are far apart from each other.

[0016] It is worth noting that: the baffle can prevent coal from falling from both sides when the belt conveyor is transporting coal, reducing material waste and the risk of equipment jamming; the figure-eight guide block can guide and gather the coal output from the belt conveyor, ensuring that it falls accurately into the second receiving hopper and avoids deviation; the first and second limit blocks can limit the first and second collecting trolleys respectively, preventing the trolleys from deviating when moving and ensuring that the trolleys are accurately connected to the discharge end.

[0017] Preferably, the feeding assembly includes two rotating rods rotatably mounted on the inner walls of both sides of the second receiving hopper, a fixed cylinder fixed to the side wall of each rotating rod, and at least two fixed plates fixed to the side wall of each fixed cylinder.

[0018] It is worth noting that when the rotating rod rotates, it drives the fixed cylinder and the fixed plate to rotate synchronously. The fixed plate can agitate and transport the coal in the second receiving hopper, avoid coal accumulation and blockage, and ensure that the material is transported evenly and continuously to the first screening plate. The setting of at least two fixed plates enhances the feeding effect, can adapt to the conveying needs of coal with different particle sizes, prevent the device from stopping due to material blockage, and improve the continuous operation capability and classification efficiency of the device.

[0019] Preferably, the first collection trolley includes a collection box disposed above the first support plate and rollers rotatably mounted on both sides of the collection box, with the lower ends of the rollers abutting against the upper end of the first support plate. The second pushing assembly includes a second fixed seat fixed to the upper end of the first support plate, a second cylinder fixed to the end of the second fixed seat away from the first collection trolley, and a second push block fixed to the output shaft of the second cylinder. The first collection trolley is provided with a buffer assembly for buffering, which includes a fixed post fixed to the end of the collection box near the second push block, a second fixed block fixed to the fixed post away from the first collection trolley, and a rubber block fixed to the second fixed block away from the first collection trolley.

[0020] It is worth noting that the rollers make the collection trolley flexible and easy for the second push component to push the trolley to adjust its position, enabling precise material collection. The cylinder-driven push component can precisely control the trolley's movement distance to adapt to different collection needs. The rubber block of the buffer component can absorb the impact force during pushing, avoiding direct rigid collision between the push block and the collection box, which would cause damage to the components, extend the service life of the device, and reduce collision noise.

[0021] Preferably, the control assembly includes a controller fixed to the upper end of the base plate and a buzzer fixed to the side wall of the controller.

[0022] It is worth noting that the controller can receive image data from the first and second camera components and weighing data from the first and second weighing platforms, enabling intelligent control of various components of the device (such as the pushing component, feeding component, and belt conveyor), automating the coal mine classification process. The buzzer can sound an alarm when the collection trolley is fully loaded due to a device malfunction, promptly reminding staff to handle the situation and prevent the malfunction from escalating or material from overflowing, effectively improving the operational safety and reliability of the device.

[0023] Preferably, the two sides of the movable frame and the upper parts of the two U-shaped blocks are attached to each other at one end.

[0024] It is worth noting that the fitting structure can limit the movement direction of the movable frame, preventing it from shifting left or right or wobbling when moving, ensuring that it always moves along the preset trajectory, and guaranteeing the precise pushing or guiding effect on the coal mine.

[0025] The present invention also provides a coal mine intelligent sorting device and a method of using it, which includes the coal mine intelligent sorting device as described above, and the method of using it is as follows: S1: Initial setup and inspection: Before use, ensure that the device is in a horizontal position, confirm that the first collection trolley and the second collection trolley are placed in the designated positions on the first support plate and the second support plate, and that the first limit block and the second limit block limit the trolley rollers to prevent the trolley from deviating. Check if the connection between the controller and the buzzer is normal, and ensure that the control component can receive signals from the first weighing platform, the second weighing platform and the camera component in real time; The controller sets the preset weight values ​​for the first and second weighing platforms, which are based on the density of the coal particles and the capacity of the collection trolley.

[0026] S2: Start-up and feeding: Connect the power supply, start the controller, and after the system self-checks, enter the standby state. Pour the crushed coal into granules evenly onto the conveyor belt of the belt conveyor. Note that the amount of coal should not be too much to avoid blockage. Then start the belt conveyor and adjust the conveying speed to make the coal move smoothly towards the second receiving hopper. The baffles and guide blocks on both sides of the belt conveyor can prevent the coal from scattering and concentrate the material through the figure-eight structure. S3: Screening process: Coal ore is evenly fed into the movable frame through the feeding component in the second receiving hopper. The rotation of the feeding component can be adjusted by the controller to control the falling speed. Then the first pushing component is activated: the first cylinder pushes the first pushing block, which drives the movable frame to move back and forth on the separation plate. The two sides of the movable frame are in contact with the upper part of the U-shaped block to ensure smooth movement. During the movement of the movable frame, the spring of the rebound component and the movable block provide buffering and rebound force to help vibrate the screening, making it easier for coal ore particles to pass through the trough on the separation plate and the second screening plate. During this process, smaller coal ore particles fall into the first collection trolley through the holes on the first screening plate, medium-sized particles fall into the first receiving hopper through the holes on the second screening plate, and finally enter the second collection trolley. Larger particles remain at the top of the separation plate and can be cleaned manually or later. S4: Monitoring and Collection: The first camera component monitors the screening process in real time, capturing the coal distribution on the moving frame and the separation plate. The image data is transmitted to the controller for analysis of screening efficiency. The second camera component monitors the filling status of the second collection trolley to ensure no overflow or abnormality. When the first weighing platform detects that the weight of the first collection trolley reaches the preset value, the controller triggers the buzzer to sound an alarm and starts the second pushing component. The second cylinder pushes the second push block to push the first collection trolley out along the first support plate. The buffer component reduces the impact during the pushing process and protects the trolley structure. Similarly, when the second weighing platform detects that the weight of the second collection trolley has reached the preset value, the controller activates the third pushing component to push the second collection trolley out, and the staff can replace it with an empty trolley in time to continue collecting. S5: Maintenance and Shutdown: After screening is completed, shut down the belt conveyor and the first push assembly, stop all actions through the controller, clean the residual coal on the separation plate, moving frame and screening plate, check the feeding assembly and push assembly for wear, lubricate or replace if necessary, regularly calibrate the weighing platform and camera assembly to ensure classification accuracy, the controller can record historical data for optimizing the production process.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. To address the issues of existing coal sorting methods being unable to integrate with intelligent identification systems and the low accuracy and efficiency of sorting and conveying coal of specific particle sizes, this device uses a first camera component to monitor the coal distribution on the separation plate and movable frame in real time. The image signal is then transmitted to the control component to analyze the screening efficiency. Simultaneously, the control component drives the first pushing component to move the movable frame back and forth on the separation plate. The rebound force provided by the rebound component enhances the vibration screening effect. Furthermore, the different apertures of the first and second screening plates enable the grading and screening of coal particles. This effectively achieves the linkage between intelligent identification and precise sorting, improving the accuracy and speed of sorting coal of specific particle sizes. 2. To address the problem of low efficiency and production interruption caused by the need to manually change boxes when they are full in traditional sorting methods, this device sets up a first weighing platform and a second weighing platform on the first and second support plates respectively. The weight of the first and second collection trolleys is monitored in real time. When the weight reaches the preset value, the control component immediately triggers a buzzer alarm and starts the second or third pushing component to push the full collection trolley out along the support plate. The staff can directly replace the empty collection trolley without stopping the entire sorting production line, which significantly reduces the intensity of manual labor, avoids production interruption, and ensures the continuous operation capability of the sorting system. 3. Addressing the issue that existing intelligent sensing technologies only focus on "identification" and fail to form a closed loop with material conveying and container management, resulting in a disconnect between "identification" and "execution," this device uses a control component as its core. It integrates the identification signal from the first camera component, the weight signals from the first and second weighing platforms, the material feeding control signal from the feeding component, and the execution signal from the pushing component to form a complete control closed loop. The control component can adjust the material feeding speed of the feeding component based on the identification results and control the container changing action based on the weight signal. This achieves the coordinated operation of the entire process of intelligent identification, precise sorting, and automatic container changing, truly realizing the unmanned and intelligent operation of the entire coal classification process and improving the overall level of automation.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To address the problems in existing technologies, such as fixed and inflexible classification and conveying paths, reliance on manual handling for container replacement leading to production interruptions, and the disconnect between the "identification" and "execution" stages preventing the formation of an intelligent closed loop, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-10 ; A coal mine intelligent sorting device and its usage method include a base plate 1, four first supports 2 fixed to the upper end of the base plate 1, U-shaped blocks 3 fixed to the upper ends of two first supports 2 on the same side, a separation plate 4 fixedly installed on the inner wall of the two U-shaped blocks 3, a movable frame 6 placed on the upper end of the separation plate 4, a first pushing component 5 set on the two U-shaped blocks 3 for pushing the movable frame 6 to move, a rebound component 11 fixed to the upper end of the separation plate 4, a first camera component fixed to the upper end of one of the U-shaped blocks 3, a trough 17 penetrating the lower end of the separation plate 4, a first screening plate 18 fixed to the inner wall of the trough 17, a solid plate 19 fixed to the end of the first screening plate 18 away from the first pushing component 5, and a component fixed to the solid plate 19 away from the first pushing component 5. The components are: a second screening plate 20 at one end of component 5; a third support 12 fixed to the upper end of the two U-shaped blocks 3; a belt conveyor 13 fixed to the third support 12; a support block 15 fixed to the upper end of the two U-shaped blocks 3; a second receiving hopper 16 fixed to the two support blocks 15 for receiving the conveyor belt of the belt conveyor 13 for outputting coal to the mine; a second support 7 fixed to the upper end of the bottom plate 1; a first bearing plate 8 fixed to the upper end of the second support 7; a first collecting trolley 9 set on the upper end of the first bearing plate 8; a second pushing assembly 10 set on the upper end of the first bearing plate 8 for pushing the first collecting trolley 9 to move; a second bearing plate 14 fixed to the upper end of the bottom plate 1; a second collecting trolley 24 and a third pushing assembly 25 set on the upper end of the second bearing plate 14; The second receiving hopper 16 is equipped with a feeding component. The second collecting trolley 24 and the first collecting trolley 9 have the same structure. The third pushing component 25 and the second pushing component 10 have the same structure. The upper end of the base plate 1 is provided with a frame, and a first receiving hopper 142 is fixedly connected to the frame. The feeding end of the first receiving hopper 142 corresponds to the discharging end of the second screening plate 20. The upper end of the base plate 1 is provided with a second camera assembly for observing the second collection trolley 24, and the upper end of the base plate 1 is provided with a control assembly. The discharge end of the second hopper 16 corresponds to the upper end of the first screening plate 18. The first bearing plate 8 is provided with a first weighing platform for weighing the first collection trolley 9, and the second bearing plate 14 is provided with a second weighing platform for weighing the second collection trolley 24.

[0032] In use, the crushed coal ore is poured onto the conveyor belt of belt conveyor 13. Belt conveyor 13 is then turned on, causing the coal ore to move towards the second receiving hopper 16. The coal ore falls into the movable frame 6 via the feeding component. Then, the first pushing component 5 is activated to push the movable frame 6, causing it to move between the two U-shaped blocks 3. This movement of the movable frame 6 allows coal ore of different sizes to fall through holes of different sizes on the trough 17 or the second screening plate 20. The coal ore falling through the holes on the trough 17 is received by the first collecting trolley 9. When the first weighing platform detects that the weight has reached the preset value, the control component activates the second pushing component 10 to push the first collecting trolley 9 away from the second pushing component 10. Similarly, the coal falling through the holes on the second screening plate 20 will be received by the first receiving hopper 142 and then fall into the second collecting trolley 24 through the first receiving hopper 142. When the second weighing platform detects that the weight of the second collecting trolley 24 has reached the preset value, the control component activates the third pushing component 25 to push the second collecting trolley 24 away from the location of the third pushing component 25, which can facilitate the staff to quickly collect coal of different particle sizes.

[0034] In this embodiment, specifically: the rebound assembly 11 includes a first fixing block 1101 fixed to the upper end of the separation plate 4, at least two springs 1102 fixed to the first fixing block 1101 near one end of the movable frame 6, and a movable block 1103 fixed to the at least two springs 1102 near one end of the movable frame 6.

[0035] It should be noted that the surfaces of the movable block 1103 and the movable frame 6 that come into contact with each other have low surface roughness. For example, they can be made by polishing, adding a sliding sleeve, or using self-lubricating materials. This smooth contact surface design can significantly reduce the sliding friction resistance experienced by the movable frame 6 in high-speed reciprocating motion, which not only avoids movement jamming but also reduces component wear, thereby extending the service life of the device.

[0037] In this embodiment, specifically: two baffles 131 are fixedly connected to the upper end of the U-shaped block 3. The ends of the two baffles 131 that are close to each other are attached to both sides of the conveyor belt of the belt conveyor 13. Guide blocks 132 are fixedly connected to the ends of the two baffles 131 that are close to each other. The downward surfaces of the two guide blocks 132 form a figure-eight shape. Two second limiting blocks 141 for limiting the second collecting trolley 24 are fixedly connected to the upper end of the second bearing plate 14. Two first limiting blocks 81 are fixedly connected to the upper end of the first bearing plate 8. The ends of the two first limiting blocks 81 that are close to each other are respectively attached to the ends of the two corresponding rollers 92 that are far apart from each other.

[0038] In this embodiment, specifically: the feeding assembly includes two rotating rods 161 rotatably mounted on the inner walls of both sides of the second receiving hopper 16, a fixed cylinder 162 fixed to the side wall of each rotating rod 161, and at least two fixed plates 163 fixed to the side wall of each fixed cylinder 162.

[0039] In this embodiment, specifically: the first collection trolley 9 includes a collection box 91 disposed above the first support plate 8 and rollers 92 rotatably mounted on both sides of the collection box 91. The lower end of the rollers 92 is in contact with the upper end of the first support plate 8. The second pushing assembly 10 includes a second fixed seat 1011 fixed to the upper end of the first support plate 8, a second cylinder 1012 fixed to the end of the second fixed seat 1011 away from the first collection trolley 9, and a second push block 1013 fixed to the output shaft of the second cylinder 1012. The first collection trolley 9 is provided with a buffer assembly for buffering. The buffer assembly includes a fixed post 21 fixed to the end of the collection box 91 near the second push block 1013, a second fixed block 22 fixed to the fixed post 21 away from the first collection trolley 9, and a rubber block 23 fixed to the second fixed block 22 away from the first collection trolley 9.

[0041] In this embodiment, specifically: the two sides of the active frame 6 and the upper parts of the two U-shaped blocks 3 are attached to each other at one end.

[0042] The present invention also provides a coal mine intelligent sorting device and a method of using it, which includes the coal mine intelligent sorting device as described above, and the method of using it is as follows: S1: Initial Setup and Checks Before use, ensure that the device is in a horizontal position, confirm that the first collection trolley 9 and the second collection trolley 24 are both placed in the designated positions on the first support plate 8 and the second support plate 14, and that the first limiting block 81 and the second limiting block 141 limit the trolley roller 92 to prevent the trolley from deviating. Check whether the connection between the controller 28 and the buzzer 29 is normal, and ensure that the control component can receive signals from the first weighing platform, the second weighing platform and the camera component in real time; The controller 28 sets the preset weight values ​​of the first and second weighing platforms, which are set according to the density of the coal particles and the capacity of the collection trolley.

[0043] S2: Start-up and material supply Connect the power supply and start the controller 28. After the system self-checks, it enters the standby state. Pour the crushed coal into granules evenly onto the conveyor belt of the belt conveyor 13. Note that the amount of coal should not be too much to avoid blockage. Then start the belt conveyor 13 and adjust the conveying speed to make the coal move smoothly towards the second receiving hopper 16. The baffles 131 and guide blocks 132 on both sides of the belt conveyor 13 can prevent the coal from scattering and concentrate the material through the figure-eight structure. S3: Screening process Coal particles are evenly fed into the movable frame 6 through the feeding component in the second receiving hopper 16. The rotation of the feeding component can be adjusted by the controller 28 to control the dropping speed. Then, the first pushing component 5 is activated: the first cylinder 52 pushes the first pushing block 53, causing the movable frame 6 to move back and forth on the separation plate 4. The two sides of the movable frame 6 are in contact with the upper part of the U-shaped block 3 to ensure smooth movement. During the movement of the movable frame 6, the spring 1102 and the movable block 1103 of the rebound component 11 provide buffering and rebound force to help vibrate the screening, making it easier for coal particles to pass through the trough 17 and the second screening plate 20 on the separation plate 4. During this process, smaller coal particles fall into the first collection trolley 9 through the holes on the first screening plate 18, medium-sized particles fall into the first receiving hopper 142 through the holes on the second screening plate 20, and finally enter the second collection trolley 24. Larger particles remain on the upper end of the separation plate 4 and can be cleaned manually or later. S4: Monitoring and Collection The first camera component monitors the screening process in real time, capturing the coal distribution on the active frame 6 and the separation plate 4. The image data is transmitted to the controller 28 for analysis of screening efficiency. The second camera component monitors the filling status of the second collection trolley 24 to ensure no overflow or abnormality. When the first weighing platform detects that the weight of the first collection trolley 9 reaches the preset value, the controller 28 triggers the buzzer 29 to issue an alarm and starts the second pushing component 10. The second cylinder 1012 pushes the second push block 1013 to push the first collection trolley 9 out along the first support plate 8. The buffer component reduces the impact during the pushing process and protects the trolley structure. Similarly, when the second weighing platform detects that the weight of the second collection trolley 24 has reached the preset value, the controller 28 activates the third pushing component 25 to push the second collection trolley 24 out, so that the staff can replace it with an empty trolley in time to continue collecting. S5: Maintenance and Shutdown After screening, shut down the belt conveyor 13 and the first push assembly 5, stop all actions via controller 28, clean the residual coal on the separation plate 4, movable frame 6 and screening plate, check for wear on the feeding assembly and push assembly, lubricate or replace if necessary, regularly calibrate the weighing platform and camera assembly to ensure classification accuracy, and the controller 28 can record historical data for optimizing the production process.

10. A coal mine intelligent sorting device and its usage method, comprising the coal mine intelligent sorting device as described in claim 9, wherein the usage method is as follows: S1: Initial setup and inspection: Before use, ensure that the device is in a horizontal position, confirm that the first collection trolley (9) and the second collection trolley (24) are placed in the designated positions on the first support plate (8) and the second support plate (14), and that the first limit block (81) and the second limit block (141) limit the trolley roller (92) to prevent the trolley from deviating. Check whether the connection between the controller (28) and the buzzer (29) is normal, and ensure that the control component can receive signals from the first weighing platform, the second weighing platform and the camera component in real time; The preset weight values ​​of the first and second weighing platforms are set by the controller (28), which are set according to the density of the coal particles and the capacity of the collection trolley; S2: Start-up and feeding: Connect the power supply, start the controller (28), and after the system self-checks, enter the standby state. Pour the crushed coal into granules evenly onto the conveyor belt of the belt conveyor (13). Note that the amount of coal should not be too much to avoid blockage. Then start the belt conveyor (13), adjust the conveying speed, and make the coal move smoothly towards the second receiving hopper (16). The baffles (131) and guide blocks (132) on both sides of the belt conveyor (13) can prevent the coal from scattering and concentrate the material through the figure-eight structure. S3: Screening process: Coal is evenly fed into the movable frame (6) through the feeding component in the second receiving hopper (16). The rotation of the feeding component can be adjusted by the controller (28) to control the dropping speed. Then the first pushing component (5) is activated: the first cylinder (52) pushes the first push block (53), causing the movable frame (6) to move back and forth on the separation plate (4). The two sides of the movable frame (6) are in contact with the upper part of the U-shaped block (3) to ensure smooth movement. During the movement of the movable frame (6), the spring of the rebound component (11) ( 1102) and the movable block (1103) provide buffering and rebound force to help vibrate the screen, making it easier for coal particles to pass through the trough (17) on the separation plate (4) and the second screening plate (20). During this process, smaller coal particles fall into the first collection trolley (9) through the holes on the first screening plate (18), medium particles fall into the first receiving hopper (142) through the holes on the second screening plate (20), and finally enter the second collection trolley (24). Larger particles remain at the top of the separation plate (4) and can be cleaned manually or later. S4: Monitoring and Collection: The first camera component monitors the screening process in real time, capturing the coal distribution on the active frame (6) and the separation plate (4). The image data is transmitted to the controller (28) for analysis of screening efficiency. The second camera component monitors the filling status of the second collection trolley (24) to ensure no overflow or abnormality. When the first weighing platform detects that the weight of the first collection trolley (9) reaches the preset value, the controller (28) triggers the buzzer (29) to issue an alarm and starts the second push component (10). The second cylinder (1012) pushes the second push block (1013) to push the first collection trolley (9) out along the first support plate (8). The buffer component reduces the impact during the pushing process and protects the trolley structure. Similarly, when the second weighing platform detects that the weight of the second collection trolley (24) has reached the preset value, the controller (28) activates the third push component (25) to push the second collection trolley (24) out, and the staff can replace the empty trolley in time to continue collecting; S5: Maintenance and shutdown: After screening is completed, shut down the belt conveyor (13) and the first push assembly (5), stop all actions through the controller (28), clean the residual coal on the separation plate (4), moving frame (6) and screening plate, check whether the feeding assembly and push assembly are worn, lubricate or replace them if necessary, regularly calibrate the weighing platform and camera assembly to ensure classification accuracy, and the controller (28) can record historical data for optimizing the production process.
