[0029] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0030] Currently, mechanical scraper cleaners are commonly used in coal preparation plants to clean belts, but this cleaning method has the following drawbacks: (1) High wear: The scraper (usually made of polyurethane or alloy steel) directly rubs against the belt surface, resulting in significant wear on the belt working surface and the scraper, which shortens the service life. (2) Low cleaning efficiency: The uneven distribution of scraper pressure leads to a large amount of material residue, requiring multiple cleanings, resulting in low cleaning efficiency; at the same time, the residue scraped off by the scraper accumulates under the cleaner, requiring secondary manual cleaning, which also increases the cleaning cost.

[0031] The conveyor belt cleaning control method provided in this application addresses the aforementioned deficiencies: when the control device detects that the conveyor belt is in operation in the first direction, it acquires the first posture information of the vortex-type air guide mechanism's outlet and the conveyor belt in the second direction; when it is determined that the first posture information is not the first preset posture information, the control device adjusts the first posture information by adjusting the second posture information of the adjustment mechanism; when the first posture information is adjusted to the first preset posture information, the control air source is introduced into the vortex-type air guide mechanism through the air inlet, forming a vortex wind in the vortex-type air guide mechanism, which is then conveyed to the conveyor belt through the air outlet. This enables non-contact cleaning of the conveyor belt, reducing conveyor belt wear compared to mechanical scraper cleaners; and the uniform wind pressure distribution of the vortex wind formed by the vortex-type air guide mechanism reduces material residue on the conveyor belt, improving cleaning efficiency.

[0032] This application provides a conveyor belt cleaning control method, applied to a conveyor belt cleaning control system. The conveyor belt cleaning control system includes a vortex-type air guide mechanism, an adjustment mechanism, and a control device. As shown in Figure 1, the conveyor belt cleaning control method may include the following steps: Step 111, in response to the control device detecting that the conveyor belt is in a running state in a first direction, the control device acquires the air outlet of the vortex-type air guide mechanism and the first position information of the conveyor belt in a second direction.

[0033] Step 112: In response to the control device determining that the first pose information is not the first preset pose information, the control device adjusts the first pose information by adjusting the second pose information of the adjustment mechanism.

[0034] Step 113: In response to the control device detecting that the first position information has been adjusted to the first preset position information, the control device controls the air source to be introduced into the vortex air guide mechanism through the air inlet, forming a vortex air in the vortex air guide mechanism, and conveying it to the conveyor belt from the air outlet.

[0035] This application provides a conveyor belt cleaning control method. When the control device detects that the conveyor belt is in operation in a first direction, it acquires the first posture information of the air outlet of the vortex-type air guide mechanism and the first posture information of the conveyor belt in a second direction. When it is determined that the first posture information is not the first preset posture information, the control device adjusts the first posture information by adjusting the second posture information of the adjustment mechanism. When the first posture information is adjusted to the first preset posture information, the control air source is introduced into the vortex-type air guide mechanism through the air inlet, forming a vortex airflow in the vortex-type air guide mechanism, which is then conveyed to the conveyor belt through the air outlet. This method enables non-contact cleaning of the conveyor belt, reducing conveyor belt wear compared to mechanical scraper cleaners. Furthermore, the vortex airflow formed by the vortex-type air guide mechanism has a uniform air pressure distribution, which can reduce material residue on the conveyor belt and improve cleaning efficiency.

[0036] Step 111 (i.e., in response to the control device detecting that the conveyor belt is in operation in the first direction, the control device acquires the first position information of the air outlet of the vortex air guide mechanism and the first position information of the conveyor belt in the second direction) will be described in detail below.

[0037] In step 111, when the control device detects that the conveyor belt is in operation in the first direction through a sensor with corresponding function, the control device obtains the first position information of the air outlet of the vortex air guide mechanism and the first position information of the conveyor belt in the second direction.

[0038] In one example, the control device includes a speed sensor for acquiring the operating speed of the conveyor belt; wherein detecting that the conveyor belt is in operation in the first direction may include: if the operating speed acquired by the speed sensor is greater than a preset speed threshold, then determining that the conveyor belt is in operation in the first direction. Optionally, the preset speed threshold may be set according to cleaning requirements (cleaning time, efficiency, etc.).

[0039] In one example, before detecting the operating speed of the conveyor belt, the cleaning control method for the conveyor belt also includes: pre-establishing a coordinate system to uniformly describe the pose of devices such as the conveyor belt, the vortex air guide mechanism, and the adjustment mechanism, which can be the position (distance) and / or attitude (angle) in the coordinate system.

[0040] It should also be noted that the position and orientation information of the conveyor belt in the second direction will not change. The aforementioned first position and orientation information can be the position and orientation information of the air outlet; or the relative position and orientation information between the air outlet and the conveyor belt.

[0041] Optionally, in this example, if the first pose information is the relative pose information between the air outlet and the conveyor belt, obtaining the first pose information of the air outlet and the conveyor belt of the vortex air guide mechanism may include: obtaining the pose information of the air outlet of the vortex air guide mechanism and the pose information of the conveyor belt in the coordinate system respectively, and determining the first pose information based on the pose information of the air outlet and the pose information of the conveyor belt, wherein the first pose information may be the relative pose information between the air outlet and the conveyor belt.

[0042] In this embodiment, the conveyor belt may include at least a belt (or conveyor belt) and at least two rollers (commonly referred to as drums or idlers) as key components. The at least two rollers can be mounted via fixed brackets and may be divided into a drive roller (or transmission roller) and a driven roller (or redirecting roller), working together in different ways to ensure stable operation of the conveyor belt and efficient transport of items (or materials).

[0043] In one example, the first direction can be the direction in which the conveyor belt runs (e.g., the conveyor belt transports materials (e.g., coal) horizontally), and can be set according to the specific application scenario of the conveyor belt. The second direction is a different direction from the first direction, such as a direction perpendicular to the first direction.

[0044] The control device will be described in detail below.

[0045] In this embodiment, the control device includes a controller and sensors for collecting operating parameters. These sensors are used to collect operating parameters of various components in the conveyor belt cleaning control system, such as at least one of a belt running sensor, a distance sensor, and an tilt sensor. Specifically, the belt running sensor can be a speed sensor used to detect the conveyor belt's running speed; the distance sensor is used to collect a first distance parameter between the air outlet and the conveyor belt; and the tilt sensor is used to collect a first angle parameter between the air outlet and the conveyor belt.

[0046] Optionally, the control device further includes a device for pre-treating the air source, such as a vapor-water separator and / or a pressure sensor. The vapor-water separator is used to dry the air source; the pressure sensor is used to monitor the air pressure of the air source and to issue an alarm (such as illuminating a red indicator light) when the air pressure exceeds a preset air pressure threshold. In one example, the first posture information includes a first angle parameter and / or a first distance parameter. The control device includes a tilt sensor and / or a distance sensor. The control device acquires the first posture information of the air outlet and the conveyor belt, including at least one of the following: acquiring a first angle parameter between the air outlet and the conveyor belt in a second direction using the tilt sensor; acquiring a first distance parameter between the air outlet and the conveyor belt in a second direction using the distance sensor; wherein the tilt sensor is mounted on a first mounting component, and the distance sensor is mounted on the air outlet side.

[0047] This application embodiment is used for cleaning the conveyor belt on one hand; on the other hand, the environment in which the conveyor belt works is dusty, and over time the dust will block the sensor, causing the sensor to lose its acquisition accuracy. At this time, it is also necessary to clean the conveyor belt.

[0048] In the control device, the tilt sensor is installed on the air outlet side (such as within a preset range of the air outlet; for example, a metal bracket is installed on the side of the air outlet (such as the left or right side) to fix the distance sensor on the bracket, so that the measuring beam of the distance sensor can be directed onto the conveyor belt surface), and is exposed to the air, making it easily covered by dust. When the distance sensor is covered by dust, it causes measurement errors. The conveyor belt cleaning control system will clean the distance sensor periodically or when the error is large. When the cleaning program is started, the control device rotates the air outlet to the angle parameter in the second preset pose information (i.e., θ2, which can be 0°), and uses compressed air to clean the surface of the distance sensor. After cleaning, the air outlet is rotated to the belt cleaning angle.

[0049] Here, the angle and distance parameters in the first preset pose information can be set according to the installation position of the conveyor belt and cleaning requirements (such as cleaning time); the angle and distance parameters in the first preset pose information can also be set according to the installation position of the distance sensor and cleaning requirements.

[0050] In one example, the control device further includes at least one of a solenoid valve, a pressure sensor, and a steam-water separator; the control device is equipped with an air inlet pipe for the aforementioned devices, which is connected to the air inlet of a vortex-type air guide mechanism. Specifically, when the solenoid valve is open, it is used to introduce air from the source into the vortex-type air guide mechanism through the air inlet; when the solenoid valve is closed, it stops introducing air from the source into the vortex-type air guide mechanism through the air inlet; the steam-water separator is used to dry the air source; and the pressure sensor is used to monitor the air pressure of the air source and to trigger an alarm when the air pressure is abnormal.

[0051] In Figure 2, the control device includes: a control cabinet 401, a belt conveyor sensor 402, a distance sensor 403, a tilt sensor 208, a solenoid valve 405, a steam-water separator 406, and a pressure sensor 407. The control cabinet 401 (including the controller, network switch, touchscreen, electrical components, etc.) is the center of the intelligent control device. Sensor signals are input to the control cabinet 401, and the control cabinet 401 outputs control actuators. The adjustment settings, control logic, and network communication of the control device are all completed within the control cabinet 401.

[0052] It should be noted that the controller can be a local controller (such as the controller in the control cabinet) and / or a remote controller (such as the host computer); generally, both local and remote controllers are set up.

[0053] Optionally, the local controller can be a programmable logic controller (PLC) or other microprocessor. The PLC connects to the sensors and actuators via point-to-point wiring.

[0054] In Figure 3, the PLC communicates with the touch screen and the host computer through a network switch to achieve local and remote monitoring. The PLC is connected to the belt drive sensor 402, distance sensor 403, tilt sensor 208, pressure sensor 407, lifting stepper motor 301, tilting stepper motor 201, and solenoid valve 405 via point-to-point wiring.

[0055] The following example illustrates the working process of the control device: 1) Initialization: Set the reference parameters through the touch screen: initial angle θ0 = 90°, air outlet angle θ threshold is 0~90°; initial distance L0 from the air outlet to belt 501 (as shown in Figure 2 belt 501) = 100mm; height h0 between the distance sensor and the air outlet = 45mm; cleaning time t0 = null.

[0056] Perform automatic calibration: the lead screw is zeroed and positioned.

[0057] 2) Control process The entire control device takes the PLC as the core, monitors the air pressure and interlocks the equipment through the signals of the pressure sensors, and realizes the adaptive adjustment of distance and angle as well as self-cleaning through the distance sensors and inclination sensors.

[0058] Start and stop the control device according to the running signal of the belt 501. When the belt 501 starts running, the PLC receives the start signal and the control device automatically turns on. When the belt 501 stops, the PLC receives the stop signal and the control device automatically turns off.

[0059] Check whether the intake air pressure is normal through the pressure sensor. If the pressure is not within the threshold range (0.6 - 0.8 MPa), the control device issues an alarm reminder.

[0060] Adjust the gap of the stainless steel strip at the air outlet according to the actual situation. The adjustment range is 0 - 3 mm. After adjustment, tighten the bolts to prevent loosening.

[0061] Tangential intake forms a swirling flow field, improving the air pressure uniformity in the air cavity, so that the air flow at the air outlet reaches uniform and stable.

[0062] Set the operating parameters on the touch screen. Include: a Set the first angle parameter θ1 = 45° between the air outlet and the conveyor belt; the actual inclination angle of the inclination sensor is θ; when the parameter θ > θ1, the control device sends a forward rotation signal to the motor; when the parameter θ < θ1, the control device sends a reverse rotation signal to the motor; when the parameter θ = θ1, the control device sends a stop signal to the motor to achieve the purpose of adjusting the air outlet angle.

[0063] b Set the distance between the air outlet and the belt 501 as L1 = 20 mm; according to the data h provided by the distance sensor, calculate the distance (i.e., the first distance parameter) L between the air outlet and the belt 501 through the formula: L = h - h0, where h: the distance between the distance sensor and the belt 501; h0: the height between the sensor and the air outlet.

[0064] When L > L1, the control device sends a forward rotation signal to the motor; when L < L1, the control device sends a reverse rotation signal to the motor; when L = L1, the control device sends a stop signal to the motor to achieve the purpose of adjusting the air outlet height.

[0065] The following describes in detail step 112 (that is, in response to the control device determining that the first pose information is not the first preset pose information, the control device adjusts the second pose information of the adjustment mechanism to adjust the first pose information).

[0066] In this step 112, the control device determines whether the first pose information is the first preset pose information; if the control device determines that the first pose information is not the first preset pose information, then adjust the second pose information of the adjustment mechanism to adjust the first pose information.

[0067] It should be noted that after each adjustment of the second pose information of the adjustment mechanism, after determining whether the adjusted first pose information is the first preset pose information, step 112 is executed until it is determined that the adjusted first pose information is the first preset pose information.

[0068] The working principle of the control device is described below with reference to Figure 4: First, the controller is used to acquire (or read) the data collected by the belt running sensor 402. The belt running sensor 402 is a speed sensor. When the belt conveyor is running, the belt running sensor 402 feeds back a signal to the controller, and the controller starts the program control.

[0069] The second step involves the controller acquiring the first distance parameter collected by the distance sensor 403 and the angle parameter collected by the tilt sensor. After acquiring the above information, the controller compares the distance parameter between the air outlet and the conveyor belt set on the touchscreen (i.e., the set value, such as the distance parameter in the first preset pose information) with the actual value fed back by the distance sensor (i.e., the first distance parameter). Then, it adjusts the forward and reverse rotation of the lifting stepper motor 301 according to the deviation until the actual value equals the set value (i.e., the actual value enters the allowable range of the set value). The controller also compares the angle parameter between the air outlet and the conveyor belt set on the touchscreen (i.e., the set value, such as the angle parameter in the first preset pose information) with the actual value fed back by the tilt sensor (i.e., the first angle parameter). Then, it adjusts the forward and reverse rotation of the tilt stepper motor according to the deviation until the actual value equals the set value (i.e., the actual value enters the allowable range of the set value).

[0070] The process involves comparing the distance parameter between the air outlet and the conveyor belt set on the touchscreen (the distance parameter in the first preset pose information) with the actual value fed back by the distance sensor (i.e., the first distance parameter). Then, the lifting stepper motor 301 is adjusted according to the deviation, controlling its forward and reverse rotation until the actual value equals the set value. This may include: determining whether L (i.e., the first distance parameter) is equal to L1 (i.e., the distance parameter in the first preset pose information). If yes, proceed to step three. If no, determine whether L is less than L1. If yes, control the lifting stepper motor 301 to reverse; if yes, control the lifting stepper motor 301 to rotate forward.

[0071] The process involves comparing the angle parameters between the air outlet and the conveyor belt set on the touchscreen (i.e., the angle parameters in the first preset pose information) with the actual value fed back by the tilt sensor (i.e., the first angle parameter). Then, the tilt stepper motor is adjusted by controlling the forward and reverse rotation based on the deviation until the actual value equals the set value. This may include: determining whether θ (i.e., the first angle parameter) is equal to θ1 (i.e., the angle parameter in the first preset pose information). If yes, proceed to step three. If no, determine whether θ is less than θ1. If yes, control the tilt stepper motor 201 to reverse; if yes, control the tilt stepper motor 201 to rotate forward.

[0072] In addition, after reading the angle parameters collected by the tilt sensor 208, the cleaning control method of the conveyor belt further includes: determining whether the operating parameters of the distance sensor meet the first preset condition. When it is determined that the operating parameters of the distance sensor do not meet the first preset condition (i.e., determining that the distance sensor is not to be cleaned), it is determined whether θ (i.e., the first angle parameter) is equal to θ1 (i.e., the angle parameter in the first preset pose information). If yes, the third step is executed. If no, it is determined whether θ is less than θ1. If yes, the tilt stepper motor 201 is controlled to reverse; if yes, the tilt stepper motor 201 is controlled to rotate forward. When it is determined that the operating parameters of the distance sensor meet the first preset condition (i.e., determining that the distance sensor is to be cleaned), it is determined whether θ (i.e., the first angle parameter) is equal to θ2 (i.e., the angle parameter in the second preset pose information). If no, it is determined whether θ is less than θ2. If yes, the tilt stepper motor 201 is controlled to reverse; if yes, the tilt stepper motor 201 is controlled to rotate forward.

[0073] Thirdly, after the actual value equals the set value, the solenoid valve is opened. Pressurized air flows from the air source through the steam-water separator 406 and the pressure sensor 407, enters the vortex-type air guide mechanism 100, and then blows onto the surface of the belt 501 to clean it. The steam-water separator 406 dries the air to prevent humid air from corroding the pipes and mechanisms.

[0074] In addition, after the controller reads the pressure parameters collected by the pressure sensor, it determines whether the pressure parameters exceed the preset pressure threshold (i.e., whether the pressure sensor is out of range). If the pressure parameters collected by the pressure sensor do not exceed the preset pressure threshold, fault diagnosis is performed. After fault diagnosis, it is determined whether there is a fault. If a fault exists, a fault output is generated. If the pressure parameters collected by the pressure sensor exceed the preset pressure threshold, a fault output is generated.

[0075] Here, faults can be displayed using indicator lights; for example, a red indicator light will illuminate to indicate a fault. Additionally, after a fault is displayed, steps one through three can be repeated.

[0076] When there is no malfunction, the air source is controlled and introduced into the vortex-type air guide mechanism through the air inlet, forming a vortex within the vortex-type air guide mechanism, and then conveyed to the conveyor belt through the air outlet.

[0077] Here, the control device in this embodiment integrates a fault self-diagnosis function, which shortens the maintenance response time.

[0078] In one example, determining whether to clean the distance sensor may include: in response to a control device determining that the operating parameters of the distance sensor meet a first preset condition, determining whether a first angle parameter is an angle parameter in a second preset pose information; in response to the control device determining that the first angle parameter is not an angle parameter in the second preset pose information, the control device adjusts the first angle parameter by adjusting the angle parameter of an angle adjustment component; in response to the control device detecting that the first angle parameter has been adjusted to an angle parameter in the second preset pose information, the control device delivers air from the air outlet to the surface of the distance sensor; wherein the first preset condition is determined based on the distance sensor's acquisition error and / or acquisition period.

[0079] For example, the operating parameters of a distance sensor include distance parameters, and the error of the distance parameters must be less than or equal to the error (such as absolute error or relative error); the acquisition period can be a fixed period or a dynamic period.

[0080] For example, the angle parameter between the air outlet and the conveyor belt (i.e., the angle parameter in the second preset pose information) is set to θ2=0°; the actual tilt angle of the tilt sensor is θ; when the parameter θ>θ2, the control device sends a forward rotation signal to the motor; when the parameter θ<θ2, the control device sends a reverse rotation signal to the motor; when the parameter θ=θ2, the control device sends a stop signal to the motor, thereby achieving the purpose of adjusting the air outlet angle.

[0081] Additionally, it should be noted that the distance parameter in the second preset pose information can be the same as the distance parameter in the first preset pose information. That is, when performing non-contact cleaning on the conveyor belt or distance sensor, the distance parameter between the air outlet and the conveyor belt is the same. After cleaning the distance sensor, the angle parameter can be adjusted to achieve non-contact cleaning of the conveyor belt. Alternatively, after cleaning the conveyor belt, the angle parameter can be adjusted to achieve non-contact cleaning of the distance sensor.

[0082] Here, whether it is the first preset pose information or the second preset pose information can mean equal to the first preset pose information or the second preset pose information; or, within the preset range of the first preset pose information or the second preset pose information, the preset range can be set according to cleaning needs.

[0083] In this embodiment, the adjustment method of the adjustment mechanism is determined by comparing the first pose information with the first preset pose information. This adjustment method is used to adjust the second pose information of the adjustment mechanism.

[0084] In one example, in response to determining that the first pose information is not the first preset pose information, adjusting the second pose information of the adjustment mechanism includes: determining the adjustment method of the adjustment mechanism based on the comparison result between the first pose information and the first preset pose information; and adjusting the second pose information of the adjustment mechanism according to the adjustment method.

[0085] For example, when the control device determines that the first pose information is greater than the first preset pose information, the control device determines the first adjustment mode of the adjustment mechanism; adjusts the second pose information of the adjustment mechanism according to the first adjustment mode; when the first pose information is less than the first preset pose information, the control device determines the second adjustment mode of the adjustment mechanism; and adjusts the second pose information of the adjustment mechanism according to the second adjustment mode.

[0086] Continuing from the above, pose includes position (distance) and / or attitude (angle). Optionally, this application may provide corresponding adjustment components for the position and angle in the pose information, such as a distance adjustment component for adjusting the position, or an angle adjustment component for adjusting the angle. Optionally, the adjustment mechanism includes an angle adjustment component and / or a distance adjustment component.

[0087] When the first posture information includes a first distance parameter, the adjustment mechanism includes a distance adjustment component. The first distance parameter of the vortex-type air guide mechanism's outlet is adjusted by adjusting the first distance parameter of the distance adjustment component in the vertical direction (i.e., the second direction). When the first posture information includes a first angle parameter, the adjustment mechanism includes an angle adjustment component. The first angle parameter of the vortex-type air guide mechanism's outlet is adjusted by adjusting the angle parameter of the angle adjustment component, thereby adjusting the first angle parameter between the outlet and the conveyor belt in the second direction.

[0088] In one example, determining the adjustment method of the adjustment mechanism based on the comparison result between the first pose information and the first preset pose information may include at least one of the following: determining the adjustment method of the angle adjustment component based on the comparison result between the first angle parameter in the first pose information and the angle parameter in the first preset pose information; determining the adjustment method of the distance adjustment component based on the comparison result between the first distance parameter in the first pose information and the distance parameter in the first preset pose information.

[0089] Optionally, in this example, adjusting the second pose information of the adjustment mechanism according to the adjustment method may include: adjusting the angle parameter of the angle adjustment component according to the adjustment method of the angle adjustment component; and / or, adjusting the first distance parameter of the distance adjustment component according to the adjustment method of the distance adjustment component.

[0090] For example, when the control device determines that the first angle parameter is greater than the angle parameter in the first preset pose information, the control device determines a third adjustment method for the angle adjustment component; adjusts the angle parameter of the angle adjustment component according to the third adjustment method; when the first angle parameter is less than the angle parameter in the first preset pose information, the control device determines a fourth adjustment method for the angle adjustment component; adjusts the angle parameter of the angle adjustment component according to the fourth adjustment method. Similarly, when the control device determines that the first distance parameter is greater than the distance parameter in the first preset pose information, the control device determines a fifth adjustment method for the distance adjustment component; adjusts the distance of the distance adjustment component according to the fifth adjustment method; and when the first distance parameter is less than the distance parameter in the first preset pose information, the control device determines a sixth adjustment method for the distance adjustment component; adjusts the distance of the distance adjustment component according to the sixth adjustment method.

[0091] In one example, if the adjustment mechanism includes an angle adjustment component and a distance adjustment component, the vortex air guide mechanism is mounted on the angle adjustment component, and the angle adjustment component is mounted on the distance adjustment component.

[0092] Here, the first angle parameter in the first pose information is adjusted by adjusting the angle parameter of the angle adjustment component, and the first distance parameter in the first pose information is adjusted by adjusting the first distance parameter of the distance adjustment component.

[0093] In Figure 5, the swirl-type air guide mechanism 100 is mounted on the angle adjustment component 200, and the angle adjustment component 200 is mounted on the distance adjustment component 300.

[0094] In the embodiments of this application, the first position information of the air outlet and the conveyor belt can be adjusted by rotating the motor forward or backward.

[0095] In one example, the angle adjustment component includes a tilting stepper motor and a first mounting component, with a vortex-type air guide mechanism mounted on the first mounting component; the angle adjustment component is adjusted by controlling the tilting stepper motor to rotate forward or reverse to drive the first mounting component to rotate, thereby adjusting the first angle parameter.

[0096] In this example, the adjustment method of the angle adjustment component is determined based on the comparison result between the first angle parameter in the first pose information and the angle parameter in the first preset pose information.

[0097] Following the above, when the control device determines that the first angle parameter is greater than the angle parameter in the first preset pose information, the control device determines a third adjustment mode for the angle adjustment component, which is to control the tilt stepper motor to rotate forward and drive the first mounting component to rotate; the angle parameter of the angle adjustment component is adjusted according to the third adjustment mode; when the first angle parameter is less than the angle parameter in the first preset pose information, the control device determines a fourth adjustment mode for the angle adjustment component, which is to control the tilt stepper motor to rotate in reverse and drive the first mounting component to rotate; the angle parameter of the angle adjustment component is adjusted according to the fourth adjustment mode.

[0098] For example, the actual tilt angle of the tilt sensor is θ; when θ>θ1 (which is a set value, such as the set value set on the touch screen), the control device sends a forward rotation signal to the motor; when θ<θ1, the control device sends a reverse rotation signal to the motor; when the parameter θ=θ1, the control device sends a stop signal to the motor, thereby achieving the purpose of adjusting the air outlet angle.

[0099] Optionally, in this example, the control device includes: a tilt sensor; the first mounting component includes: a worm gear reducer, a first tilt drive shaft, a first support, a first end cover, a second end cover, and a second tilt drive shaft; wherein, the first end cover and the second end cover are respectively installed at both ends of the vortex-type air guide mechanism, the first support is used to position the first tilt drive shaft, the tilt sensor and the second tilt drive shaft are connected by a key, the second tilt drive shaft is fixedly connected to the second end cover, and the first tilt drive shaft is fixedly connected to the first end cover; the tilting stepper motor drives the first tilt drive shaft to rotate through the worm gear reducer, and sequentially connects the drive, the first support, the first end cover, the vortex-type air guide mechanism, the second end cover, the second tilt drive shaft, and the tilt sensor through the first tilt drive shaft.

[0100] In Figure 6, the angle adjustment component includes: a tilting stepper motor 201, a worm gear reducer 202, a first tilting drive shaft 203, a drive shaft support 204 (i.e., the first support), a drive shaft side air chamber end cover 205 (i.e., the first end cover), a positioning shaft air chamber end cover 206 (i.e., the second end cover), and a second tilting drive shaft 207. The tilting stepper motor 201 drives the first tilting drive shaft 203 after being reduced in speed by the worm gear reducer 202. The first tilting drive shaft 203 and the drive shaft side air chamber end cover 205 are connected by a key to achieve the adjustment of the air outlet angle. The large reduction ratio and self-locking performance of the worm gear reducer 202 ensure the accuracy and stability of the air outlet angle control. Optionally, the worm module M=1, the worm gear teeth Z=40, the reduction ratio 40:1, and the worm is driven by a stepper motor (e.g., shaft diameter D=8mm).

[0101] The drive shaft support 204 positions the first tilt drive shaft 203 to enhance transmission rigidity.

[0102] The drive shaft-side air chamber end cap 205 and the positioning shaft air chamber end cap 206 are connected to the vortex-type air guide mechanism 100. The outer shaft end of the end cap 206 is inserted into the outer air chamber tube 101, positioning the outer air chamber tube 101, and the sealing ring in the sealing groove seals the air chamber. The inner air chamber tube 102 is inserted into the inner shaft hole of the drive shaft-side air chamber end cap 205, positioning the inner air chamber tube 102. The positioning holes on the drive shaft-side air chamber end cap 205 and the positioning shaft air chamber end cap 206 ensure the installation and positioning accuracy of the first stainless steel laminate 103.

[0103] The second tilting drive shaft 207 and the positioning shaft air chamber end cover 206 are also connected by a key. The second tilting drive shaft 207 and the first tilting drive shaft 203 serve as both rotating shafts and supports for the vortex-type air guide mechanism 100.

[0104] The tilt sensor 208 is also connected to the second tilt drive shaft 207 by a key; optionally, the tilt sensor 208 adopts a single-turn rotary encoder, which feeds back the actual tilt angle value through a rotary pulse feedback signal, thereby improving the feedback accuracy.

[0105] The dual-axis tilt sensor 208 is fixed on the second tilt drive shaft 207 to provide a signal for adjusting the air outlet angle.

[0106] In one example, the distance adjustment component includes a lifting stepper motor, a lifting member, and a second mounting member; wherein, the second mounting member is located on the lifting member and is used to install the angle adjustment component; the distance adjustment component is adjusted by driving the lifting member to move up and down by the forward or reverse rotation of the lifting stepper motor, so as to adjust the first distance parameter.

[0107] In this example, the adjustment method of the distance adjustment component is determined based on the comparison result between the first distance parameter in the first pose information and the distance parameter in the first preset pose information.

[0108] Following the above, when the control device determines that the first distance parameter is greater than the distance parameter in the first preset pose information, the control device determines the fifth adjustment mode of the distance adjustment component, which is to drive the lifting component to move up and down by rotating the lifting stepper motor in the forward direction; the distance of the distance adjustment component is adjusted according to the fifth adjustment mode; when the first distance parameter is less than the distance parameter in the first preset pose information, the control device determines the sixth adjustment mode of the distance adjustment component, which is to drive the lifting component to move up and down by rotating the lifting stepper motor in the reverse direction; the distance of the distance adjustment component is adjusted according to the sixth adjustment mode.

[0109] For example, the distance (i.e., the actual value) L between the air outlet and the belt can be calculated using the following formula: L = h - h0 where h is the distance between the distance sensor and the belt, and h0 is the height between the distance sensor and the air outlet.

[0110] When L > L1, the control device sends a forward rotation signal to the motor; when L < L1, the control device sends a reverse rotation signal to the motor; when L = L1, the control device sends a stop signal to the motor, achieving the purpose of adjusting the height of the air outlet.

[0111] In addition, it should be noted that the forward or reverse rotation can be set according to specific usage requirements. For example, when the first distance parameter is less than the distance parameter in the first preset pose information, the motor rotates forward, which will not be elaborated here.

[0112] In one example, the lifting member includes at least one lift; when the number of lifts is multiple, the linkage shafts between the lifts are connected by a plum blossom coupling.

[0113] Optionally, in this example, the lifting member includes: a driving screw lift, a driven screw lift 303, a driving plum blossom coupling, a driven plum blossom coupling 305, and a synchronous transmission link 306; the second mounting member includes a main mounting platform 307 and an auxiliary mounting support; wherein, the lifting stepper motor 301 drives the driving screw lift 302, and the driving screw lift 302 synchronizes the rotation to the driven screw lift 303 through the driving plum blossom coupling 304, the synchronous transmission link 306, and the driven plum blossom coupling 305, driving the main mounting platform 307 and the auxiliary mounting support 308 to lift and lower synchronously.

[0114] In FIG. 7, the distance adjustment component includes: a lifting stepper motor 301, a driving screw lift 302, a driven screw lift 303, a driving plum blossom coupling 304, a driven plum blossom coupling 305, a synchronous transmission link 306, a main mounting platform 307, and an auxiliary mounting support 308; wherein, optionally, the screw lift 302 uses a two-phase stepper motor. The lifting stepper motor 301 drives the driving screw lift 302, and the driving screw lift 302 synchronizes the rotation to the driven screw lift 303 through the driving plum blossom coupling 304, the synchronous transmission link 306, and the driven plum blossom coupling 305, and the synchronous lifting and lowering of the main mounting platform 307 and the auxiliary mounting support 308 realizes the on-line adjustment of the distance between the air outlet and the conveyor belt.

[0115] Here, the structure of two plum blossom couplings + transmission link meets the requirement of synchronous lifting while eliminating the installation requirement for the coaxiality of the driving and driven screw lifts, without requiring precision requirements for the installation position before installation, and can be quickly applied through simple adjustment after installation.

[0116] In one example, the auxiliary mounting support 308 positions the second tilt drive shaft 207 to enhance the transmission rigidity.

[0117] In this embodiment, the air is conveyed to the conveyor belt through an air outlet located at the first preset pose information (i.e., the first pose information between the air outlet and the conveyor belt is the first preset pose information) to achieve non-contact cleaning of the conveyor belt. Alternatively, the air is conveyed to the distance sensor through an air outlet located at the second preset pose information (i.e., the second pose information between the air outlet and the conveyor belt is the second preset pose information) to achieve non-contact cleaning of the distance sensor.

[0118] As mentioned above, the position and orientation information of the conveyor belt in the second direction will not change; that is to say, adjusting the second position and orientation information of the adjustment mechanism mainly refers to adjusting the position and orientation information of the air outlet, thereby completing the adjustment of the first position and orientation information.

[0119] The following describes step 113 in detail (i.e., in response to the control device detecting that the first position information has been adjusted to the first preset position information, the control device controls the air source to be introduced into the vortex air guide mechanism through the air inlet, forming a vortex air in the vortex air guide mechanism, and conveying it to the conveyor belt through the air outlet).

[0120] In step 113, when the adjusted first posture information is determined to be the first preset posture information, the air source is controlled to be introduced into the vortex-type air guide mechanism through the air inlet, and a vortex wind is formed in the vortex-type air guide mechanism.

[0121] Here, the swirling air guide mechanism is used to form a swirling airflow (i.e., a swirling wind) inside the air source, and then transform it into an air curtain through its outlet.

[0122] In one example, the swirling air guide mechanism includes an annular air chamber with an air inlet and an air outlet. The air outlet and the air inlet are set at a preset angle on the annular air chamber, such as being set vertically. The annular air chamber is used to form a swirling airflow from the input air source.

[0123] Optionally, the air source for underground compressed air or compressed air mainly comes from a surface air compressor system. Air compressor: The air compressor is the core equipment for generating compressed air. In coal mines, air compressors are usually installed on the surface to ensure safety. The air compressor uses an explosion-proof motor to drive a screw or piston to compress air to 0.6-0.8 MPa, and then dries the air to remove moisture.

[0124] In addition, although the existing pneumatic cleaning technology achieves non-contact cleaning, the following problems still exist: (1) the duct structure design is unreasonable, and the air outlet velocity varies greatly under standard working conditions (e.g., the difference is >30%); (2) the blown air is uneven; (3) the cleaning angle is fixed; (4) the compressed air consumption is large; and (5) the noise level is too high.

[0125] The use of an annular air chamber in this application embodiment can achieve the following technical effects: (1) Using underground compressed air or compressed air as a power source, a stable high-pressure air curtain is formed, realizing non-contact cleaning of the belt, avoiding mechanical contact wear, reducing belt wear rate, extending belt replacement cycle, and thus reducing maintenance costs; (2) Using tangential swirl air supply technology, on the one hand, the entire airflow path from air inlet to air outlet is smooth, and no turbulence phenomenon is formed during the entire airflow process, reducing the energy loss of compressed air path; on the other hand, it eliminates the phenomenon of uneven air pressure distribution, reduces material residue, and can better remove water and extremely fine sticky materials adhering to the belt surface, making cleaning more thorough and improving cleaning efficiency.

[0126] Optionally, in this example, controlling the air source to be introduced into the swirl-type air guide mechanism through the air inlet to form a swirling airflow in the swirl-type air guide mechanism includes: introducing the air source into the annular air chamber through the air inlet on the outer pipe of the air chamber to form a swirling airflow along the annular direction of the annular air chamber.

[0127] Optionally, in this example, the swirl-type air guide mechanism includes an outer air chamber tube and an inner air chamber tube, with the inner air chamber tube placed inside the outer air chamber tube. The outer air chamber tube includes a tube body and an axial gap in the tube body. The gap includes a first end and a second end. The first end extends tangentially along the tube body and forms an air outlet with the second end. The air inlet and air outlet are set at a preset angle on the tube body. The outer shaft end of the second end cap is inserted into the tube body, and the inner air chamber tube is inserted into the shaft inner hole of the first end cap to form an annular air chamber.

[0128] In this embodiment, the annular air cavity can be used to form an annular air duct.

[0129] Here, the function of the first end extending tangentially along the pipe body is to improve the overall performance of the equipment by adjusting the airflow path, expanding the coverage area, or enhancing functional adaptability. This extension (such as the air guide plate, 1011 in Figure 9) can extend the airflow jet distance, allowing the wind to cover a wider area, so that the air curtain can be transmitted radially along the roller to the belt, thereby improving the efficiency of cleaning the conveyor belt.

[0130] Additionally, the length of the slit is less than or equal to (i.e., a through slit) the length of the tube body; the width of the slit can be set according to cleaning requirements or device design requirements.

[0131] Here, in this embodiment of the application, a through-type gap is formed at the air outlet, making the airflow at the air outlet more stable, the airflow straight and not scattered, improving the directionality of the air curtain, and reducing the generation of noise compared with existing pneumatic cleaning technology.

[0132] It should be noted that the outer extension can be set to a specific angle or shape to change the airflow direction.

[0133] In one example, the swirling air guide mechanism also includes stainless steel plates used to adjust the size of the through-type slit.

[0134] Optionally, in this example, the vortex-type air guide mechanism further includes a first stainless steel plate, a first fixed mounting member, a second stainless steel plate, and a second adjustable mounting member; wherein, at the air outlet, the first fixed mounting member is used to install the first stainless steel plate on the outer wall at the second end of the pipe body, the second adjustable mounting member is used to install the second stainless steel plate on the first stainless steel plate, and the second stainless steel plate and the second adjustable mounting member can be used to adjust the size of the gap.

[0135] Here, the first stainless steel lamination can serve as a structural support for the second stainless steel lamination, providing a foundation for the stable installation, functional realization, and system coordination of the second component. Specifically, the first stainless steel lamination includes an adjacent first surface and a second surface. The first surface is the inner surface of the first stainless steel lamination, which is an arc-shaped surface. The second surface is the plane on which the second stainless steel lamination is installed, realizing the transition from the arc surface to the plane. The first stainless steel lamination is fixed to the outer wall of the pipe body by a first fixing mounting component (such as two internal hexagonal flat head bolts). The two ends of the first stainless steel lamination are respectively fixed to the first end cap and the second end cap.

[0136] Optionally, the second stainless steel sheet may have a U-shaped groove structure in the middle.

[0137] In Figures 8, 9, 10, and 11, the swirl-type air guide mechanism includes: an outer air chamber pipe 101, an inner air chamber pipe 102, a first stainless steel plate 103, a first fixed mounting component 104, a second stainless steel plate 105, and a second adjustable mounting component 106. Optionally, the first fixed mounting component and the second adjustable mounting component can be screws, bolts, etc., such as flat-head screws.

[0138] In this system, an air source enters the mechanism to form a uniform swirling airflow, and stainless steel sheets form a through-type gap at the air outlet. The size of the through-type gap can be adjusted by adjusting the second adjustable mounting piece 106.

[0139] In the embodiments of this application, the swirl-type air guide mechanism can be used to form an annular air duct and a through-type variable gap air duct.

[0140] The annular air duct consists of an inner tube 102 housed within an outer tube 101 (e.g., the inner diameter of the outer tube 101 is Φ28mm, and the outer diameter of the inner tube 102 is Φ15mm) to form an annular air cavity (e.g., an annular air cavity with a height of 6.5mm). When airflow enters the annular air cavity, it is guided along the annular direction (as shown in Figure 11) to the air outlet. Part of the air is blown out through the outlet, while the other part is spiraled along the annular air cavity towards the other end, ultimately filling the entire annular air cavity and generating a stable pressure, thus achieving uniform air pressure at the air outlet.

[0141] The through-type variable gap air duct refers to an air duct formed by adjusting the size of the through-type gap by adjusting the second adjustable mounting component 106. The air outlet of this duct consists of a fixed end and an adjustable end. The fixed end and the air chamber are integral (i.e., part of a vortex-type air guide mechanism), and the adjustable end is a double-layer stainless steel laminate structure (i.e., a first stainless steel laminate and a second stainless steel laminate). The first surface of the first stainless steel laminate 103 is arc-shaped (e.g., an arc with an inner radius of 20mm), and the second surface is flat, achieving a transition from the arc surface to the flat surface. The second surface provides an installation platform for the second stainless steel laminate 105. The second stainless steel laminate 105 uses a U-shaped groove structure in the middle (e.g., 9mm in length and 6mm in width) to achieve 0-3mm air duct adjustment, and is fixed to the first stainless steel laminate 103 by three hexagonal bolts.

[0142] In some examples of this application, to further improve the air outlet efficiency, the structure at the air outlet can be designed with rounded corners or a circle.

[0143] For example, the inner edge of the outer tube 101 of the air chamber is rounded, which is conducive to air flow, avoids air turbulence when adjusting the through gap, and improves air outlet efficiency.

[0144] For example, the second end of the outer tube 101 of the air chamber is chamfered at 45° to improve the direction of the air outlet and reduce air volume loss.

[0145] In some examples of this application, an elongated design may be adopted to stabilize airflow. For example, the second stainless steel lamination adopts a straight elongated structure to stabilize the airflow at the outlet and improve the airflow directionality.

[0146] The conveyor belt cleaning control system in this embodiment of the application also includes a chute. After being conveyed to the conveyor belt from the air outlet, the chute contains the residue on the conveyor belt. The residue is blown away by high-pressure air and falls into the chute in a parabolic trajectory, avoiding material accumulation. Compared with mechanical scraper cleaners, this reduces the cost of manual secondary cleaning.

[0147] In addition, by conveying air through the air outlet to the conveyor belt, non-contact cleaning of the conveyor belt is achieved, which further reduces the energy consumption of the conveyor belt operation by reducing the frictional resistance of the belt operation.

[0148] This application provides a conveyor belt cleaning control system for executing the aforementioned conveyor belt cleaning control method. The conveyor belt cleaning control system includes: a vortex-type air guide mechanism 100, an adjustment mechanism, and a control device 400; wherein the vortex-type air guide mechanism 100 is mounted on the adjustment mechanism and has an air inlet and an air outlet for forming a vortex airflow from an air source; the control device 400 is used to, when detecting that the conveyor belt is in operation in a first direction, acquire first position information of the air outlet of the vortex-type air guide mechanism 100 and the conveyor belt in a second direction; and adjust the first position information by adjusting the second position information of the adjustment mechanism; and when detecting that the first position information has been adjusted to a first preset position information, control the air source to be introduced into the vortex-type air guide mechanism 100 through the air inlet, forming a vortex airflow within the vortex-type air guide mechanism 100, and conveying it to the conveyor belt through the air outlet.

[0149] Optionally, the control device 400 is further configured to determine the adjustment mode of the adjustment mechanism based on the comparison result between the first pose information and the first preset pose information; the control device 400 adjusts the second pose information of the adjustment mechanism according to the adjustment mode.

[0150] Optionally, the adjustment mechanism includes an angle adjustment component 200 and / or a distance adjustment component 300; and the control device 400 is further configured to: determine the adjustment mode of the angle adjustment component 200 based on the comparison result of the first angle parameter in the first pose information and the angle parameter in the first preset pose information; and determine the adjustment mode of the distance adjustment component 300 based on the comparison result of the first distance parameter in the first pose information and the distance parameter in the first preset pose information.
