[0040] Exemplary embodiments of the present application will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application can be more thoroughly understood and so that the scope of the present application can be completely conveyed to those skilled in the art.
[0041] In order to solve the problem that the belt conveyor stockyard is prone to blockage and lacks a better detection device and method,
[0042] An embodiment of the present application provides a belt conveyor stockyard blockage detection device, as shown in the figure, the device comprises: Figure 1
[0043] The detection unit 21 is used to detect the material overflow information of the overflow port.
[0044] Exemplarily, the detection unit can detect that the overflow port has material overflow, thereby generating material overflow information based on the material overflow of the overflow port, and realizing real-time monitoring of the belt conveyor stockyard blockage.
[0045] When the belt conveyor stockyard is blocked and the overflow material is overflowed through the overflow port, the control unit is used to generate a control signal based on the material overflow information, and the control signal is used to control the working state of the belt conveyor.
[0046] Through the above technical solution, the belt conveyor stockyard blockage detection device provided by the present application solves the problem that the belt conveyor stockyard is prone to blockage and lacks a better detection device and method. The present application sets a detection unit, which is used to detect the material overflow information of the overflow port; and a control unit, which is used to generate a control signal based on the material overflow information, and the control signal is used to control the working state of the belt conveyor. In the above scheme, since the belt conveyor can be controlled based on the material overflow information, the blockage situation can be accurately detected at the first time, the accidents caused by the belt conveyor are reduced, and the hidden dangers of the equipment are eliminated.
[0047] The guarantee device is stable in operation, has fast response speed, stable performance, adjustability and long service life. 5The control unit generates a control signal to control the working state of the belt machine to inhibit or prevent the material bin of the belt machine from being further blocked after determining that there is material overflow.
[0048] In an embodiment,
[0049] The detection unit includes a displacement transmission module and a displacement detection module.
[0050] The displacement transmission module is used to convert the material overflow action of the overflow port into a displacement action of a movable component in the displacement transmission module.
[0051] The displacement detection module is used to convert the displacement action into the material overflow information.
[0052] The movable component in the displacement transmission module can be a telescopic guide rail. When the material blocking baffle pushes the telescopic guide rail of the blocking detector to move outward, the material overflow information can be obtained.
[0053] In an embodiment,
[0054] The movable component is provided with a magnetic unit.
[0055] The displacement detection module is provided with at least two Hall magnetic sensing elements.
[0056] The Hall magnetic sensing elements are used to detect the movement information of the magnetic unit to generate the material overflow information.
[0057] The distance between the at least two Hall magnetic sensing elements is positively correlated with the scale of the material bin of the belt machine.
[0058] The working principle of the belt machine material bin blocking detection device is shown in Figure 2 The Hall magnetic switch shown in the figure is a Hall magnetic sensing element, and the circuit principle of the control box is shown in Figure 3As shown, when the magnetic unit on the movable part, that is, the sensing magnet, reaches the same position as the Hall magnetic switch one, the Hall magnetic switch one generates a switching signal, the normally open point of the relay K1 is closed, and the relay K1 is actuated. When the telescopic guide rail continues to move inward, the sensing magnet reaches the same position as the Hall magnetic switch two, the Hall magnetic switch two generates a switching signal, the normally open point of the relay K2 is closed, and the relay K2 is actuated. The relay K1 actuates the normally open point of the relay K3, the relay K2 actuates the normally open point of the relay K4, the normally open points of the relays K3 and K4 are connected in series to actuate the relay K5, and the normally open point of the relay K5 is connected in series to the control loop of the driving motor of the belt conveyor. Thus, by arranging at least two Hall magnetic sensing elements, the Hall magnetic switch one is actuated, and then the Hall magnetic switch two is actuated to output a signal, thereby avoiding the shutdown caused by the misoperation of a single signal and avoiding the misoperation caused by a single signal of a mechanical contact type limit switch.
[0059] For example, the embodiment of the present application adopts a sensing magnet and a non-contact Hall magnetic proximity switch to avoid the misoperation caused by the short travel of a mechanical contact type limit switch, the shutdown caused by the alarm, and the non-operation caused by the long travel of the limit switch.
[0060] For example, the embodiment of the present application is designed to adjust the length of the telescopic guide rail, flexibly detect the position according to the volume of the belt conveyor magazine, and improve the detection accuracy.
[0061] By means of the above technical scheme, the belt conveyor magazine blockage detection device provided by the present application can solve the problem that there is a lack of a better detection device and method for the blockage of the belt conveyor magazine. The present application is provided with a detection unit for detecting material overflow information of the overflow port, a control unit for generating a control signal based on the material overflow information, and the control signal is used to control the working state of the belt conveyor. In the above scheme, the belt conveyor can be controlled based on the material overflow information, the blockage can be accurately detected at the first time, the accidents caused by the belt conveyor can be reduced, the equipment hazards can be eliminated to ensure the stable operation of the equipment, and the device has the characteristics of fast response speed, stable performance, adjustability, and long service life.
[0062] Further, as the implementation of the above Figure 1 device, the embodiment of the present application further provides a belt conveyor magazine blockage detection method for controlling the above Figure 1 device. As shown in the above Figure 4 , the method comprises the following steps.
[0063] S101, in the case that one Hall magnetic sensing element is triggered, determining first material overflow information;
[0064] S102, generating a deceleration rotation control signal based on the first material overflow information.
[0065] For example, if it is determined that only the first Hall magnetic sensing unit is triggered, and other Hall magnetic sensing units are not triggered, it is proved that the material overflow is not serious, and the first material overflow information is determined. At this time, the belt machine deceleration rotation control signal is generated to control the belt machine to run at a deceleration, so as to slow down the speed of transporting the material to the warehouse, and thus to inhibit the material overflow.
[0066] In an embodiment, the method further comprises:
[0067] In the case that at least two Hall magnetic sensing units are triggered, the second material overflow information is determined, wherein the second material overflow information comprises the interval time length between the triggering of the first Hall magnetic sensing unit and the triggering of the second Hall magnetic sensing unit.
[0068] In the case that the interval time length is less than the first preset time length, a stop control signal is generated based on the second material overflow information.
[0069] For example, if at least two Hall magnetic sensing units are triggered in succession, it is proved that the material overflow is serious, and the second material overflow information is determined. The second material overflow information contains the interval time length between the triggering of the first Hall magnetic sensing unit and the triggering of the second Hall magnetic sensing unit caused by the material overflow. If the interval time length is short, it is proved that the first and second Hall magnetic sensing units are triggered in succession, the interval time length is less than the first preset time length, and the material overflow is serious. At this time, the stop control signal is generated to prevent the material overflow from being aggravated.
[0070] In an embodiment, the method further comprises:
[0071] In the case that the interval time length is greater than or equal to the first preset time length and less than or equal to the second preset time length, a reverse rotation control signal is generated based on the second material overflow information,
[0072] The reverse rotation control signal comprises a reverse rotation speed, and the reverse rotation speed is negatively correlated with the interval time length.
[0073] For example, if the interval time triggered by the first and second Hall magnetic sensing elements is greater than the first time interval but less than or equal to the second preset time interval, it is proved that the material overflow is moderate, and a reverse rotation control signal can be generated to control the belt conveyor to rotate reversely, so as to bring back the blocked and overflowed materials reversely, thereby reducing the material overflow. The speed of the reverse rotation of the belt conveyor is negatively correlated with the interval time, that is, the shorter the interval time, the more serious the blockage, and accordingly, the faster the speed of the reverse rotation of the belt conveyor, so as to balance the material overflow.
[0074] In an embodiment, the method further comprises:
[0075] In a case where the interval time is greater than the second preset time interval and less than or equal to the third preset time interval, an intermittent rotation control signal is generated based on the second material overflow information.
[0076] For example, if the interval time is greater than the second preset time interval and less than or equal to the third preset time interval, it is proved that the current material overflow situation is relatively controllable. At this time, an intermittent rotation control signal is generated to control the belt conveyor to rotate intermittently, so as to generate vibration, vibrate the blocked materials, and slow down the conveying speed to reduce the material overflow.
[0077] In an embodiment, the method further comprises:
[0078] In a case where the interval time is greater than the third preset time interval, the rotation speed of the belt conveyor is recalculated based on the interval time.
[0079] For example, if the interval time is greater than the third preset time interval, it is proved that there is a material blockage situation, but the situation is controllable. At this time, the rotation speed of the belt conveyor is recalculated based on the interval time at which the current material touches the first and second Hall magnetic sensing elements, so that the belt conveyor can run based on the new rotation speed. It can be understood that the recalculated rotation speed of the belt conveyor is lower than the initial rotation speed, and the material overflow situation is reduced by re-planning the rotation speed of the belt conveyor.
[0080] For example, the method determines the severity of the material overflow by obtaining the interval time at which the first and second Hall magnetic sensing elements are triggered due to the material overflow, and sets different control strategies of the belt conveyor according to different material overflow situations, so as to more targetedly control the rotation of the belt conveyor and more quickly dredge the materials or prevent the materials from being further blocked when the material overflow occurs.

[0084] The embodiment of the present application provides an electronic device, which comprises at least one processor and at least one memory connected with the processor, and the processor is used for calling program instructions in the memory to perform the belt machine stockyard blockage detection method.
