[0020] During coal unloading operations using tippers or material reclaimers, coal quality often leads to hopper locking failure or stack collapse during the reclaiming process, easily causing sudden large material heads on the conveyor belt and resulting in material spillage along the conveyor belt. There is a technical problem in this field of how to control the conveyor belt flow rate to prevent material spillage along the conveyor belt.
[0021] To address the aforementioned technical problem of controlling belt flow to prevent material spillage along the route, this invention proposes a belt flow control device, method, equipment, medium, and product. The implementation details of this invention are described below for ease of understanding and are not essential for implementing this solution.
[0022] Example 1 Figure 4 This is a schematic diagram of the structure of a belt flow control device provided in an embodiment of this application, as shown below. Figure 4 As shown in the technical solution of this embodiment, a belt flow control device is provided, including: a support frame installed above the belt conveyor; a slide rail assembly disposed on the support frame, the slide rail assembly extending along the running direction of the belt conveyor; a gate plate slidably disposed within the slide rail assembly; a movable crossbar spanning above the support frame; a track disposed on the support frame; and a movable carrier cooperating with the track and supporting the movable crossbar; an electric push rod connected to the movable crossbar, the electric push rod being used to drive the movable crossbar to move horizontally along the track; and a linkage assembly connecting the movable crossbar and the gate plate, the linkage assembly being used to convert the horizontal movement of the movable crossbar into the oblique movement of the gate plate along the slide rail assembly.
[0023] The technical problem this embodiment aims to solve is that fixed gate-type scraper devices cannot adapt to the problems of blockage and spillage caused by large material heads due to different material characteristics. In bulk conveyor belt operations, the density, particle size, and other physical properties of the transported materials vary, and the opening degree of the fixed gate-type device cannot be adjusted: a smaller opening is needed to avoid large material heads when transporting wet, sticky coal, but the fixed gate cannot meet this requirement; a larger opening is needed to ensure transport capacity when transporting loose coal, which is also unsuitable. This incompatibility easily leads to instantaneous large material heads, causing problems such as blockage in the transfer hopper, spillage along the conveyor belt, and collapse of the stacker boom, affecting operational efficiency and equipment safety.
[0024] In this embodiment, the gate's position is flexibly adjusted through a collaborative structure consisting of a support frame, a slide rail assembly, a gate, a movable crossbar, a track, a moving carrier, an electric push rod, and a connecting rod assembly. The support frame is installed above the conveyor belt, and the slide rail assembly extends along the running direction. The gate is slidably mounted within the slide rail, and the movable crossbar spans above the frame. The track and the moving carrier cooperate to support the crossbar. The electric push rod drives the crossbar to move horizontally, and the connecting rod assembly converts this horizontal movement into oblique movement of the gate. For example, when transporting wet, sticky coal, the controller controls the electric push rod to shorten its stroke, causing the crossbar to move to the left, and the connecting rod causes the gate to move obliquely downwards to reduce the opening. When transporting loose coal, the push rod extends its stroke, the crossbar moves to the right, and the gate moves obliquely upwards to increase the opening, adapting to different material requirements.
[0025] The technical solution in this embodiment, through a structural design that dynamically adjusts the position of the gate, effectively adapts to the physical property requirements of different materials. This device can adjust the opening degree in real time, preventing the generation of large material heads and reducing problems such as material blockage and spillage. Applied to BD4 and BD6 belt conveyors, it has performed well for one year, with no material blockage or spillage caused by large material heads; its stable and reliable structure ensures continuous operation and equipment safety.
[0026] Example 2 Based on the above embodiments, the slide assembly is an inclined plate, and the inclined plate is at a preset angle to the running direction of the belt conveyor; the lower edge of the gate is arc-shaped, and the edge of the gate is covered with a wear-resistant alloy layer.
[0027] The technical problem this embodiment aims to solve is how to design a gate for flow control to improve cutting effect, wear resistance, and adaptability. Traditional gates suffer from problems such as unreasonable shape (e.g., straight edges easily scratch the belt), easy edge wear, and improper slide angle leading to material accumulation: straight-edge gates do not cut thoroughly and easily damage the belt, and the cutting effect decreases after wear; when the slide angle is not suitable, the cut material is easily retained, causing secondary blockage and affecting the accuracy of flow control.
[0028] In this embodiment, the slide assembly uses an inclined plate at a preset angle (e.g., 45°) to the belt running direction. The lower edge of the gate is arc-shaped and covered with a wear-resistant alloy layer. The inclined plate guides the material to slide smoothly away, avoiding accumulation; the arc-shaped edge fits the belt surface, thoroughly cutting excess material while preventing scratches on the belt; the wear-resistant alloy layer improves the edge's wear resistance. When transporting ores with larger particle sizes, the arc-shaped edge precisely cuts excess material, and the inclined plate allows the material to slide along the inclined surface; the wear-resistant alloy layer reduces wear rate over long-term use, reducing the frequency of gate replacement.
[0029] The technical solution in this embodiment improves the cutting effect and device durability through the design of the inclined plate slide and the arc-shaped wear-resistant gate. The arc-shaped edge fits the belt to ensure cutting accuracy, the inclined plate guides the flow to reduce accumulation, and the wear-resistant layer extends the service life.
[0030] Example 3 Based on the above embodiment, the track is an L-shaped horizontal track, and the mobile carrier includes rollers that match the horizontal track, as well as a connecting seat for fixing and supporting the moving crossbar.
[0031] The technical problem this embodiment aims to solve is ensuring the stable and smooth horizontal movement of the moving crossbar to guarantee the accuracy of the gate's position adjustment. If the moving crossbar wobbles, jams, or shifts during movement, it will cause gate position deviation: traditional support structures are unstable, and the crossbar is prone to tilting when driven by the electric push rod, preventing the gate from reaching the target position, leading to large material heads or insufficient flow, and affecting operational efficiency.
[0032] In this embodiment, the track is an L-shaped horizontal track (e.g., angle steel), and the moving vehicle includes rollers that match the track and a connecting seat for fixing and supporting the crossbar. The L-shaped track provides support and guidance, ensuring that the crossbar moves only horizontally; the rollers reduce frictional resistance, making the movement smoother; the connecting seat firmly fixes the crossbar, preventing swaying and deviation. For example, when the electric push rod drives the crossbar, the rollers roll smoothly within the L-shaped track, and the connecting seat keeps the crossbar horizontal, ensuring no tilting even under large thrust, thus guaranteeing the linearity and stability of the movement.
[0033] The technical solution in this embodiment achieves stable and smooth horizontal movement of the crossbar through the cooperation of an L-shaped track and a moving carrier with rollers. This structure eliminates swaying and jamming problems and improves the accuracy of gate position adjustment. Applied to the BD6 belt conveyor, the device operates without jamming.
[0034] Example 4 Figure 1 This is a schematic flowchart of a belt flow control method provided in an embodiment of this application, as shown below. Figure 1 As shown, in the technical solution of this embodiment, a belt flow control method based on any of the belt flow control devices in the above embodiments is provided, including: step S01, obtaining the physical property parameters of the material being transported on the belt conveyor; step S02, determining the target position of the gate according to the physical property parameters; step S03, driving the gate to move to the target position to control the instantaneous flow of the belt conveyor.
[0035] The technical problem this embodiment aims to solve is how to control the gate to adapt to real-time changes in material characteristics. Manual adjustment requires machine shutdown, affecting continuity; the inability to adjust in real time according to material parameters easily leads to large material heads or wasted transport capacity, causing material blockages or increased costs.
[0036] In the technical solution of this embodiment, by obtaining the physical property parameters of the material (including the image, particle size, density, etc. of the material); querying the preset mapping table according to the parameters, matching the position interval and calculating the accurate target position; driving the gate to the target position. For example, when the image detects that the height of the material exceeds the rated value and the sensor shows a higher density, the controller queries the mapping table to determine that the gate needs to move to the small opening interval, and then calculates the accurate position through the following algorithm to ensure stable flow.
[0037] The technical solution of this embodiment realizes the dynamic adjustment of the flow rate through an intelligent control method that automatically obtains parameters and accurately matches positions. This method does not require manual intervention, has a fast response speed, and adapts to the real-time changes of the material. After being applied to the belt conveyor supporting the dumper, the operation continuity is improved, and there is no material blockage caused by untimely adjustment.
[0038] Example 5 Based on the above embodiment, in step S02, determining the target position of the gate according to the physical property parameters includes: step S21, querying the preset mapping table of physical property parameters and gate positions; step S22, matching the corresponding position interval in the mapping table according to the current physical property parameters; step S23, calculating the accurate target position within this position interval.
[0039] The technical problem to be solved in this embodiment is how to determine the target position of the gate according to the physical property parameters to ensure the accuracy of flow control.
[0040] In the technical solution of this embodiment, query the preset mapping table of physical property parameters - gate positions (established based on experimental data, including the position intervals corresponding to different densities and particle sizes); match the interval according to the current parameters; calculate the accurate position through the interpolation algorithm. For example, when the material density is detected to be 1.2 g / cm³ and the particle size is 5 mm, query the mapping table to obtain the interval of 10 - 15 cm, and interpolate to calculate the accurate position of 12.5 cm.
[0041] The technical solution of this embodiment realizes the rapid and accurate determination of the gate position through the combination of the mapping table and interpolation calculation.
[0042] Example 6 Based on the above embodiment, in step S03, driving the gate to move to the target position to control the instantaneous flow rate of the belt conveyor includes: step S31, controlling the electric push rod to start; step S32, the electric push rod drives the moving cross bar supported by the moving vehicle to perform a horizontal displacement; step S33, converting the horizontal displacement into an oblique movement of the gate through a connecting rod, so that the gate reaches the target position.
[0043] The technical problem to be solved in this embodiment is how to stably drive the gate to move to the target position to achieve flow control.
[0044] In the technical solution of this embodiment, the electric push rod is controlled to start to provide stable power. The electric push rod drives the cross bar supported by the moving vehicle to move horizontally, and the cooperation between the track and the vehicle ensures smoothness. The connecting rod assembly converts the horizontal displacement into an oblique movement of the gate plate so that it reaches the target position. For example, when the electric push rod extends at a constant speed, the cross bar moves smoothly along the L-shaped track, and the connecting rod accurately converts the movement direction, and the gate plate reaches the target position without jamming or shaking.
[0045] In the technical solution of this embodiment, through the coordinated action of the electric push rod, the moving vehicle and the connecting rod assembly, the stable drive and accurate positioning of the gate plate are realized. The drive mode of this embodiment has sufficient power and smooth movement conversion, ensuring that the gate plate arrives quickly and accurately. Applied to the BD6 belt conveyor, no drive failure has occurred in one year of operation, ensuring the continuity of operation and the safety of the equipment.
[0046] Example 7 Figure 2 It is a schematic structural diagram of a belt flow control device provided by an embodiment of the present application. As Figure 2 shown, in the technical solution of this embodiment, a belt flow control device is provided, including: a parameter acquisition module for acquiring the physical property parameters of the transported material on the belt conveyor; a position calculation module for determining the target position of the gate plate according to the physical property parameters; a gate plate drive module for driving the gate plate to move to the target position to control the instantaneous flow of the belt conveyor.
[0047] The technical problem to be solved in this embodiment is how to control the gate plate to adapt to the real-time changes of the material characteristics. Manual adjustment requires shutdown operations, which affects continuity; it cannot be adjusted in real time according to the material parameters, easily leading to large material heads or waste of transportation capacity, resulting in blockage or increased costs.
[0048] In the technical solution of this embodiment, by acquiring the physical property parameters of the material (including the image, particle size, density, etc. of the material); querying the preset mapping table according to the parameters, matching the position interval and calculating the accurate target position; driving the gate plate to the target position. For example, when the image detects that the height of the material exceeds the rated value and the sensor shows a higher density, the controller queries the mapping table to determine that the gate plate needs to move to the small opening interval, and then calculates the accurate position through the following algorithm to ensure stable flow.
[0049] In the technical solution of this embodiment, through the intelligent control method of automatically acquiring parameters and accurately matching positions, the dynamic adjustment of the flow is realized. This method does not require manual intervention, has a fast response speed, and adapts to the real-time changes of the material. After being applied to the belt conveyor supporting the dumper, the continuity of operation has been improved, and no blockage caused by untimely adjustment has occurred.

[0057] Example 9 Based on the above embodiments, this embodiment provides an application example.
[0058] This application example provides a belt flow control device and method.
[0059] Fields of bulk material belt conveyor operations such as stockpiling operations and loading and unloading operations.
[0060] The present invention relates to the technical field of bulk material belt conveyor operations, and is particularly applicable to bulk material transport belt conveyors supporting a car dumper, a reclaimer, a stacker, etc., for controlling the instantaneous flow rate of the belt conveyor and avoiding problems such as material blockage and spillage caused by large material heads.
[0061] During the operation of the car dumper, due to reasons such as coal quality, the hopper cannot lock the material, or during the reclaimer's material taking process, there is a collapse of the stack, etc., which brings a large material head to the corresponding transport belt conveyor, that is, a large instantaneous flow rate on the belt (the weight of coal passing through per unit time), thereby causing technical problems such as blockage of the transfer hopper, spillage of the belt along the way, and dropping of the stacker boom.
[0062] During coal unloading by tippers or material handling by reclaimers, coal quality (such as wet, sticky coal) can cause hopper locking failure or collapse during material handling, easily leading to a sudden large material head on the conveyor belt (the weight of material passing through per unit time far exceeds the rated transport capacity). This problem can cause: material blockage in the transfer hopper, affecting operational efficiency; material spillage along the conveyor belt, increasing cleanup costs; and stacker boom collapse, threatening equipment safety.
[0063] Fixed gate-type scraper devices cannot adapt to the transportation needs of different materials (differences in density and particle size), resulting in low flow control accuracy and poor adaptability.
[0064] To prevent spillage and hopper blockage caused by sudden high flow rates on the conveyor belt, the technical solution of this application adds a mechanical device at the inlet of the conveyor belt to scrape off excess material. Due to the varying densities of the transported materials, the opening and position of the scraping device are adjusted accordingly to ensure a constant conveying capacity of the conveyor belt.
[0065] Belt flow control device: A 45° inclined iron plate is installed in the direction of belt conveyor operation to cut excess material running on the belt. Iron plates on both sides of the cutting device serve as connecting structures for the cutting plate. This gives the fixed gate-type belt flow control device its basic functions. The structure is as follows: Figure 3 As shown.
[0066] Because the types, particle sizes, densities, and other physical properties of the materials transported on belt conveyors differ, the height of the transported materials varies. Under normal operating conditions on the same belt conveyor, when transporting material A, the material reaches height A, and any material exceeding height A needs to be cut off. Similarly, when transporting material B, the material reaches a normal height B, and any portion exceeding height B needs to be cut off. Likewise, there are various materials such as C, D, and E, and the target position of the gate of the material scraping mechanism needs to be adjusted accordingly based on the different materials.
[0067] The slide-type belt flow control device uses a sloping plate as the bottom support frame of the slide, with steel structures on both sides serving as side stops. A movable crescent plate is installed above the slide; the position of the crescent plate relative to the slide controls the size of the material outlet. The outlet size can be continuously varied, and the inclined steel plate at any position provides a support frame, thus ensuring high support strength. The structure of the slide-type belt flow control device is as follows: Figure 4 As shown.
[0068] The structure and movable gate of the belt flow control device are as follows: Figure 4As shown, the horizontally moving crossbar is supported on both sides of the steel structure on both sides of the belt flow control device. Angle steel is installed on the steel structure as a moving track, and a moving carrier is arranged on the track as a horizontal support for the moving crossbar. The crossbar moves horizontally under the drive of an electric push rod. The crossbar moves horizontally under the drive of the electric push rod, and the connecting rod, as a force transmission mechanism, drives the crescent plate to move. As the push rod stroke increases, the crossbar pushes forward, and the connecting rod drives the crescent plate to move diagonally upward. The control flow is as follows: Figure 5 As shown.
[0069] First, determine the belt flow rate. Then, calculate the electric actuator stroke corresponding to the target crescent plate height and obtain the current electric actuator stroke. Determine if the difference between the two is zero. If the difference is zero, proceed directly to the normal operation stage and the process ends. If the difference is not zero, drive the electric actuator to move to the corresponding position according to the difference, and then proceed to the normal operation stage.
[0070] That is, this application example provides a belt flow control device, including: Support frame installed above the belt conveyor; A slide rail assembly is disposed on the support frame, the slide rail assembly extending along the running direction of the belt conveyor; A crescent-shaped plate slidably disposed within the slide rail assembly; A movable crossbar spanning above the support frame; A track is provided on the support frame, and a mobile vehicle cooperates with the track and supports the movable crossbar; An electric push rod connected to the movable crossbar, the electric push rod being used to drive the movable crossbar to move horizontally along the track; A linkage assembly connecting the moving crossbar and the crescent plate, the linkage assembly being used to convert the horizontal movement of the moving crossbar into the oblique movement of the crescent plate along the slide assembly.
[0071] The slide rail assembly includes: An inclined plate is positioned at a preset angle to the direction of travel of the belt conveyor.
[0072] The lower edge of the crescent plate is arc-shaped, and the edge of the crescent plate is covered with a wear-resistant alloy layer to improve the wear resistance of the crescent plate and its cutting effect on materials.
[0073] The track is a horizontal track made of angle steel, and the moving trolley includes rollers that match the angle steel track, as well as a connecting seat for fixing and supporting the moving crossbar, so as to ensure that the moving crossbar moves horizontally stably and smoothly.
[0074] The system also includes a controller, which is electrically connected to the electric actuator. The controller is used to receive external signals and control the extension and retraction stroke of the electric actuator to adjust the position of the crescent plate.
[0075] This also includes: An image acquisition device installed above the belt conveyor is used to acquire image data of the material and send it to the controller. A density sensor is installed below the belt conveyor to detect the density of the material and send the data to the controller; the acquired material characteristic parameters support the controller's intelligent control of the electric actuator.
[0076] The technical solution in this application example adopts a belt flow control device with a sliding movable gate. Depending on the type of coal, the electric push rod pushes the crossbar, and the horizontal movement of the crossbar adjusts the opening distance of the gate. The material passing through the cross section is controlled according to the angle. Under constant belt speed, the cross section size determines the throughput.
[0077] In this application example, the movable gate of the belt flow control device is supported by an inclined iron plate when it is in any position during operation, giving the working mechanism great working rigidity and strength.
[0078] This device has been applied to BD4 and BD6 belt conveyors and has been running for one year with good results.
