[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figures 1 to 4 As shown, an embodiment of the present invention provides a coal bunker system for preventing coal from blocking and overflowing, the coal bunker system for preventing coal from blocking and overflowing comprises a silo 10 and a coal blockage detection assembly 20, the silo 10 is arranged below a coal conveying device 100, an observation port 11 is opened on the side wall of the silo 10, the coal blockage detection assembly 20 comprises a mounting plate 21 and a level meter 22, the level meter 22 is electrically connected to the coal conveying device 100, the level meter 22 has a rotating shaft 221, one end of the rotating shaft 221 passes through the mounting plate 21, a detection blade 222 is arranged on the rotating shaft 221, an arc-shaped guard 23 is arranged on the mounting plate 21, the arc-shaped guard 23 is arranged above the detection blade 222, and the mounting plate 21 is rotatable relative to the silo 10 so that the detection blade 222 and the arc-shaped guard 23 can enter and exit the silo 10 through the observation port 11.

[0028] Specifically, the mounting plate 21 is rotatable relative to the silo 10, so that the mounting plate 21 has a first position and a second position. When in the first position, the detection blade 222 and the arc-shaped shield 23 penetrate into the interior of the silo 10 to achieve real-time and accurate monitoring of the coal blockage; when switched to the second position, the detection blade 222 and the arc-shaped shield 23 are moved out of the silo 10, thereby facilitating the user's daily inspection and maintenance work, reducing maintenance costs, and improving the stability and reliability of the system operation. In addition, the observation port 11 can also provide the user with a visual channel for intuitively viewing the internal conditions of the silo 10, which is convenient for further cleaning of the coal blockage. In this embodiment, a handle 24 is provided on the mounting plate 21.

[0029] In addition, the level meter 22 can be set as a rotary paddle level meter 22, and the detection blade 222 on the rotating shaft 221 can rotate freely according to the filling state of the coal. Once a coal blockage occurs, the blade stops rotating. This change is immediately captured by the level meter 22 and converted into an electrical signal, which is quickly fed back to the coal conveying device 100, thereby stopping the transportation of coal in time and effectively preventing the deterioration of the coal blockage.

[0030] In addition, the arc-shaped shield 23 is located above the detection blade 222, which not only effectively avoids the problem of accidental touch caused by the coal directly hitting the detection blade 222 during transportation, but its arc-shaped design also guides the flow of coal and prevents coal from accumulating above the shield, further improving the accuracy of coal blockage detection and the overall performance of the system.

[0031] In summary, the coal bunker system for preventing coal blockage and coal overflow provided in the embodiment of the present invention, through the ingenious rotation design of the mounting plate 21 and the silo 10, and the careful structural design of the arc-shaped shield 23, not only realizes the real-time monitoring and effective prevention and control of coal bunker blockage, but also greatly improves the maintenance convenience and operation efficiency of the system, and provides strong support for the intelligent and automated development of coal storage and transportation.

[0032] like Figure 1 As shown, in some embodiments, the detection blade 222 is set to a cross shape, so that the blade can contact the coal more comprehensively during the rotation process, thereby improving the detection sensitivity. Whether it is fine particles or large accumulations of coal, the cross-shaped blade can timely sense the flow state of the coal through its multi-directional tentacles, ensuring that the coal blockage situation can be captured quickly and accurately. In this embodiment, the shape of the observation port 11 can be set as needed, such as round, square, etc., as long as it can facilitate the detection of the entry and exit of the blade 222 and the arc-shaped shield 23.

[0033] In some embodiments, a threaded hole 212 is provided on the mounting plate 21, and the level meter 22 has an external threaded section 223, which is detachably screwed into the threaded hole 212 to ensure that the level meter 22 will not loosen or fall off during operation in the silo 10, thereby ensuring the accuracy and stability of the detection.

[0034] Specifically, the mounting plate 21 can be divided into an inner side 214 and an outer side 213. The motor of the level meter 22 is mounted on the outer side 213 of the mounting plate 21, which is not only convenient for wiring and debugging of the motor, but also avoids the interference of the motor with the internal environment of the silo 10, thereby ensuring the accuracy of detection. A fixing seat 211 is provided on the inner side 214 of the mounting plate 21, and a threaded hole 212 is provided in the fixing seat 211. The other end of the rotating shaft 221 passes through the threaded hole 212 steadily and penetrates into the interior of the silo 10, while the detection blade 222 is cleverly mounted on this end of the rotating shaft 221, located on the inner side 214 of the mounting plate 21, i.e., inside the silo 10. Such a design not only ensures that the detection blade 222 can fully contact with the coal material and realize real-time monitoring of the coal blocking situation, but also makes the installation of the entire level meter 22 more secure, effectively resisting the influence of the complex environment inside the silo 10.

[0035] Furthermore, when the level meter 22 needs to be maintained or replaced, the user only needs to simply rotate the external thread section 223 to easily remove the level meter 22 from the mounting plate 21 without large-scale disassembly of the entire coal bunker system, which greatly reduces maintenance costs and time costs.

[0036] Furthermore, the level meter 22 has a flange 224, a flange hole 225 is provided on the flange 224, and a mounting hole 215 corresponding to the flange hole 225 is provided on the mounting plate 21. Connecting bolts are detachably installed in the flange hole 225 and the mounting hole 215, thereby further consolidating the connection between the level meter 22 and the mounting plate 21 to ensure that it can remain stable under any working conditions and will not loosen due to vibration or impact.

[0037] It should be noted that the flange 224 design and the threaded hole 212 design in the embodiment of the present invention are not mutually exclusive, but can be freely selected according to actual needs and working conditions. The user can flexibly decide whether to use a single threaded hole 212 connection or combine the flange 224 with the threaded hole 212 to achieve a more stable connection effect according to factors such as the specific configuration of the coal bunker system, installation space, and maintenance convenience. This design flexibility not only improves the adaptability of the system, but also provides users with more choices and meets the application needs in different scenarios.

[0038] In this embodiment, the coal blocking detection components 20 are provided in two groups, and the two groups of coal blocking detection components 20 are relatively arranged on both sides of the silo 10. Among them, the silo 10 has a first side wall 12 and a second side wall 13, and the first side wall 12 and the second side wall 13 are relatively located on both sides of the coal conveying device 100. The two groups of coal blocking detection components 20 are respectively located on the first side wall 12 and the second side wall 13, which can realize all-round monitoring of the flow state of coal, can timely capture the flow changes of coal, and send out corresponding alarm signals.

[0039] Furthermore, the coal blocking detection component 20 is arranged directly below the coal conveying device 100. The coal blocking detection component 20 is located directly below the coal conveying device 100, and can most directly monitor the flow state and accumulation of coal after it flows out, and can more timely capture abnormal changes in the flow of coal, such as slowing flow rate, increasing accumulation height, etc., which are precursors of coal blocking. Once these abnormal changes are detected, the coal blocking detection component 20 will immediately send out an alarm signal to remind the operator to take timely measures to prevent the occurrence of coal blocking.

[0040] In addition, the coal blockage detection component 20 is arranged directly below the coal conveying device 100, which can also effectively avoid the direct impact and wear of the coal on the detection component. During the coal conveying process, the coal particles may generate a large impact force due to friction, collision, etc. If the detection component is directly exposed to the coal flow, it is easy to be damaged. By arranging it below the coal conveying device 100, the natural accumulation and flow characteristics of the coal flow can be used to form a certain protection effect on the detection component.

[0041] like Figure 2 and Figure 3 As shown, in some embodiments, the coal bin system for preventing coal overflow also includes a locking assembly 30, which is used to connect the mounting plate 21 and the silo 10 to lock the mounting plate 21 relative to the silo 10. This can not only effectively prevent the mounting plate 21 from being displaced or loosened due to external factors such as vibration and impact, but also ensure that the coal blockage detection assembly 20 always maintains the correct position and posture inside the silo 10, thereby realizing accurate monitoring of the flow state of the coal.

[0042] Furthermore, the locking assembly 30 includes a screw rod 31 and a nut. A through hole 216 is provided on the mounting plate 21. One end of the screw rod 31 is connected to the silo 10. The other end of the screw rod 31 passes through the through hole 216, and the nut is screwed onto the screw rod 31, thereby achieving a tight lock between the mounting plate 21 and the silo 10. In the process of tightening the nut, it is necessary to ensure that the threads between the nut and the screw rod 31 are tightly and evenly matched to avoid unstable connection due to looseness or deflection. At the same time, it is also necessary to adjust the tightening force of the nut according to actual needs to ensure that the locking assembly 30 can not only firmly connect the mounting plate 21 and the silo 10, but also can be easily disassembled and reinstalled when necessary.

[0043] In another embodiment, the locking assembly 30 includes a locking rod and a locking sleeve, a locking hole is provided on the locking sleeve, the locking sleeve is provided in one of the silo 10 and the mounting plate 21, the locking rod is slidably provided in the other of the silo 10 and the mounting plate 21, and the locking rod can be movably provided in the locking hole, so that the locking rod can be flexibly moved to the position of the locking sleeve when needed and inserted into the locking hole. During the locking process, the operator only needs to slide the locking rod to the position of the locking sleeve and then insert it into the locking hole. Since the lock rod and the locking hole are tightly and stably matched, once the lock rod is inserted into the locking hole, the mounting plate 21 and the silo 10 can be effectively locked together. This locking method is not only simple to operate, convenient and fast, but also can provide sufficient locking force to ensure the stability and reliability of the coal bunker system during operation.

[0044] like Figure 1 As shown, in some embodiments, the coal bunker system for preventing coal blockage and coal overflow further includes a cleaning component 40, which includes a driver 41 and a cleaning blade 42. The cleaning blade 42 is arranged to fit the inner wall of the silo 10, and the output end of the driver 41 is transmission-connected with the cleaning blade 42. The driver 41 is used to drive the cleaning blade 42 to rotate in the silo 10, so as to clean the coal material adhered to the inner wall of the silo 10, effectively prevent the occurrence of coal blockage and coal overflow, and ensure the smooth operation of the coal bunker system. The driver 41 can be set as a motor or a pneumatic motor.

[0045] Furthermore, the cleaning components 40 are provided in two groups, the silo 10 has a first coal dropping point and a second coal dropping point, and the two groups of cleaning components 40 are respectively provided at the first coal dropping point and the second coal dropping point. Specifically, the silo 10 has a third side wall 14 and a fourth side wall 15, and the third side wall 14 and the fourth side wall 15 stand opposite to each other in the conveying direction of the coal conveying device 100, forming a guiding channel for the flow of coal. When the coal pours out of the coal conveying device 100, they will first fall on the first coal dropping point of the third side wall 14. Since the coal has a certain kinetic energy and impact force, they will rebound after hitting the third side wall 14, and then fall again on the second coal dropping point of the fourth side wall 15. This rebound and change in the drop point not only increases the distribution range of the coal in the silo 10, but may also cause the coal to accumulate and stick at a specific position. The two groups of cleaning components 40 are respectively arranged at the first coal drop point and the second coal drop point of the third side wall 14 and the fourth side wall 15, which not only ensures the comprehensiveness and thoroughness of cleaning, but also improves the cleaning efficiency, making the flow of coal in the silo 10 smoother and reducing the risk of coal blockage and coal overflow. Figure 1 The middle arrow A indicates the flow direction of the coal transported by the coal conveying device 100 in the silo 10 .

[0046] Furthermore, the cleaning assembly 40 also includes a cleaning brush 43, which is arranged on the cleaning blade 42, which not only enhances the cleaning ability of the cleaning assembly 40 on the bonded coal material, but also makes the cleaning process more detailed and comprehensive.
