Description

Technical Field

[0001] The invention relates to the technical field of material replenishment in a loading building, and in particular to an automatic material level monitoring device for a loading hopper based on a loading building and a monitoring system thereof. Background Art

[0002] Loading buildings, as key facilities in the logistics warehousing and transportation system, play an important role in cargo loading, unloading and transshipment. They are usually designed with mechanized devices such as cranes and conveyor belts to achieve efficient and orderly loading of goods. However, traditional loading buildings mostly rely on manual operations, which are not only inefficient but also difficult to adapt to the urgent needs of modern logistics for automation and intelligence.

[0003] In loading building operations, material level management of the loading hopper is crucial. Accurate monitoring of the material level is not only related to the precise control of the loading volume, but also the key to ensuring transportation safety and equipment integrity, especially when handling bulk materials, such as coal, sand, ore, grain, cement and sugar. These materials are often stacked tightly and in various shapes, which puts higher requirements on material level monitoring. During the bulk material loading process, due to the limited volume of the hopper, frequent refilling becomes the norm. In order to ensure loading efficiency, it is necessary to continuously monitor the material level and realize automatic refilling. However, the existing automatic monitoring devices are often unable to cope with bulk materials.

[0004] Although there are many material level monitoring devices available in the market, such as ultrasonic and infrared level meters, these sensors often fail due to dust interference when facing bulk materials. The dust generated during the bulk material replenishment process not only blocks the sensor's line of sight, but may also cause dust accumulation inside the sensor, thereby affecting the measurement accuracy and stability. Although radar level meters can adapt to the bulk material monitoring environment to a certain extent, their high price and complex maintenance procedures, such as regular dust blowing, make them face many challenges in practical applications. In addition, the attenuation effect of dust on radar signals will also cause the level meter to respond more slowly, further affecting the monitoring effect and system stability.

[0005] Chinese patent document CN115009878B discloses an automatic material replenishment system based on material level monitoring of a loading building, comprising a measuring rod, a detection head connected to the side wall of the measuring rod, a rotating linkage rod connected to the top of the measuring rod through a connecting assembly, a connecting rope fixedly connected to one end of the rotating linkage rod away from the measuring rod, a limit switch provided on one side of the rotating linkage rod, a small wire wheel provided on the other side of the rotating linkage rod, the end of the connecting rope is wound around the outer surface of the small wire wheel, and a large wire wheel is fixedly connected to the end of the small wire wheel; however, the following defects still exist in the implementation process:

[0006] The device in the above-mentioned document uses a mechanical contact method to monitor the material level of the hopper above the loading building in real time, which solves the problem that the traditional level meter is easily disturbed by dust. However, the device in the above-mentioned document uses a rope sensor for displacement monitoring, and its accuracy is affected by many factors, such as the elasticity and friction resistance of the rope, resulting in errors in the measurement results. Summary of the invention

[0007] The object of the present invention is to provide a loading hopper material level automatic monitoring device and a monitoring system based on a loading building, so as to solve the problem that the device proposed in the above background technology uses a pull rope sensor for displacement monitoring, and its accuracy is affected by many factors, such as the elasticity of the pull rope, friction resistance, etc., resulting in errors in the measurement results.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0009] An automatic monitoring device for the material level of a loading hopper based on a loading building comprises a hopper bin and a feeding valve; a second connecting plate is fixedly connected to the lower end of the hopper bin, an upper end of the feeding valve is fixedly connected to the lower end of the second connecting plate, a cylinder is fixedly connected to one side of the second connecting plate, and a telescopic rod of the cylinder penetrates the upper end of the second connecting plate and extends to the lower part, a connecting rod is slidably connected to a side of the second connecting plate close to the cylinder, a lower end of the connecting rod and the telescopic rod of the cylinder are fixedly connected to the first connecting plate, and a sensing component is arranged at the upper end of the first connecting rod;

[0010] The sensing component includes a connecting block 1, a lower end of the connecting block is fixedly connected to an upper end of a connecting rod 1, a force plate is movably connected to one side of the connecting block, a limit block is symmetrically fixedly connected to an inner cavity of the connecting block 1, two limit blocks are slidably connected to a thrust block, a first push rod assembly is fixedly connected to the middle of the inner cavity of the connecting block 1, a force assembly is arranged in the middle of one side of the thrust block close to the force plate, the force assembly is used to monitor the material level of the charging hopper, a second push rod assembly is arranged at the lower part of one side of the thrust block close to the force plate, the second push rod assembly is used to drive the force plate to flip and unfold, a force rod is fixedly connected to the upper end of the connecting block 1, the force rod passes through the outer surface of the hopper bin and extends to the inner cavity of the hopper bin.

[0011] The above technical solution is adopted. In this solution, when it is necessary to monitor the material level in the loading hopper, the second push rod assembly is operated, so that the second push rod assembly can be used to drive the force-bearing plate to flip and unfold toward the side away from the first push rod assembly, and then the telescopic rod of the cylinder drives the connecting plate one to move upward. Since the connecting plate one is fixedly connected to the connecting rod one, when the connecting plate one moves, it will drive the connecting rod one to move upward together, and then the connecting rod one is used to drive the sensing component and the force-bearing rod to move upward together. Since the force-bearing rod penetrates the outer surface of the hopper bin and extends to the inner cavity of the hopper bin, when the force-bearing rod moves, it will drive the sensing component to enter the inner cavity of the hopper bin. When there is material stored in the inner cavity of the hopper bin, during the movement of the sensing component, the material will exert a force on the force-bearing plate, driving the force-bearing plate toward It flips and contracts in the direction of the first push rod assembly, and when the force-bearing plate is subjected to force, the force will be transmitted to the force-bearing assembly, and then the force-bearing assembly can be used to sense the force, and then the data is transmitted to the data center; when the sensing assembly moves upward in the inner cavity of the hopper bin, when the force-bearing plate is not subjected to external force, under the support of the second push rod assembly, the force-bearing plate will not exert force on the force-bearing assembly, and then the force-bearing plate transmits the data of not feeling the force to the data center, and the data center determines whether there is still material stored in the hopper by whether the force-bearing assembly senses the force, and then the data center can determine the position height of the material in the inner cavity of the hopper bin according to the contracted length of the cylinder telescopic rod, and control the lifting funnel through the data center whether to transport materials into the inner cavity of the hopper bin.

[0012] A further improvement of the technical solution of the present invention is that the force-bearing component includes an outer shell 1, which is fixedly connected to the thrust block, a pressure sensor is fixedly connected to the side of the inner cavity of the outer shell 1 away from the force-bearing plate, a spring 1 is fixedly connected to the side of the pressure sensor close to the force-bearing plate, a docking rod 1 is fixedly connected to the side of the spring 1 away from the pressure sensor, and the docking rod 1 is fixedly connected to the force-bearing plate on the side away from the pressure sensor.

[0013] The above-mentioned technical solution is adopted. In this solution, since the docking rod 1 is fixedly connected to the force-bearing plate, when the force-bearing plate is subjected to the force and flips and contracts toward the direction of the first push rod assembly, it can drive the docking rod pair to apply a force to the spring 1, and then drive the spring pair to apply a force to the pressure sensor, so that the pressure can be sensed by the pressure sensor, and then the sensed data can be transmitted to the data center by the pressure sensor. When the force-bearing plate is not subjected to the force, it can be supported by the docking rod 1 through the spring pair.

[0014] A further improvement of the technical solution of the present invention is that: the second push rod assembly includes a second shell, the second shell is fixedly connected to the thrust block, an electromagnet is fixedly connected to the side of the inner cavity of the second shell away from the force plate, a connecting rod is fixedly connected to the middle of the electromagnet, a spring is fixedly connected to the side of the electromagnet close to the force plate, an iron block is fixedly connected to the side of the spring away from the electromagnet, the iron block is slidably connected to the second connecting rod, a docking rod is fixedly connected to the side of the iron block away from the electromagnet, the docking rod is fixedly connected to the force plate, and the docking rod is slidably connected to the second connecting rod.

[0015] The above-mentioned technical scheme is adopted. In this scheme, when it is necessary to drive the force-bearing plate to flip and unfold in the direction away from the first push rod assembly, the electromagnet is controlled to be powered off through the controller, and then the electromagnet will release the magnetic attraction of the iron block, and then under the elastic force of the spring two, the spring two will be driven to stretch, and then the iron block and the docking rod two will be pushed together to move in the direction of the force-bearing plate, and then the docking rod two is used to drive the force-bearing plate to flip and unfold in the direction away from the first push rod assembly. When the force-bearing plate flips and unfolds, it is pulled by the spring two, so that the flipping angle of the force-bearing plate in the direction away from the first push rod assembly can be controlled to avoid the flipping angle of the force-bearing plate being too large, and then some materials enter the inner cavity of the connecting block one from the gap, and then the position of the force-bearing plate is stuck.

[0016] A further improvement of the technical solution of the present invention is that: the first push rod assembly includes an electric push rod, which is fixedly connected to the middle part of the inner cavity of connecting block one, the output end of the telescopic rod of the electric push rod is fixedly connected to connecting block two, the middle part of connecting block two is rotatably connected to connecting block three, the side of connecting block three away from the electric push rod is rotatably connected to connecting block four, and the side of connecting block four close to the thrust block is fixedly connected to the thrust block.

[0017] The above technical solution is adopted. In this solution, after the sensing component completes the monitoring of the material level in the inner cavity of the hopper bin, when the sensing component needs to be reset, the force-bearing plate needs to be flipped and reset. In order to prevent materials from entering the inner cavity of the connecting block one from the gap and then affecting the reset of the force-bearing plate, it is necessary to clean the position of the inner cavity of the connecting block one close to the force-bearing plate, so that the telescopic rod of the electric push rod can be used to push the connecting block two and the connecting block three to move toward the direction of the force-bearing plate. Since the connecting block three is fixedly connected to the connecting block four, the connecting block four can be used to push the thrust block toward the force-bearing plate. The outer shell 1 and the outer shell 2 are both fixedly connected to the thrust block, so that when the thrust block moves, the thrust block and the force-bearing component can be driven to move together, and then, with the cooperation of the thrust block and the force-bearing component, the force-bearing plate can be driven to flip and unfold in the direction away from the first push rod assembly, so that the gap between the force-bearing plate and the connecting block 1 can be expanded, and then, when the thrust block moves, the materials that enter the inner cavity of the connecting block 1 through the gap can be pushed out of the inner cavity of the connecting block 1, so as to avoid these materials from blocking the force-bearing plate when the force plate is flipped and reset, thereby affecting the normal use of the device.

[0018] A further improvement of the technical solution of the present invention is that the thrust block is symmetrically fixedly connected with a sliding block, the sliding block is T-shaped, and the sliding block on the same side is slidably connected with the limit block.

[0019] The above technical solution is adopted, in which a slider is symmetrically fixedly connected to the thrust block, and then the slider is slidably connected to the limit block, so that the position of the thrust block can be limited when the thrust block moves, thereby preventing the thrust block from deviating from the track during movement.

[0020] A further improvement of the technical solution of the present invention is that a material prevention component is arranged on the side of the force-bearing rod close to the force-bearing plate, and the material prevention component includes a shell three, which is fixedly connected to the force-bearing rod, a rubber block is slidably connected to the inner cavity of the shell three, and a spring three is fixedly connected to the upper end of the rubber block and the inner cavity of the shell three.

[0021] The above-mentioned technical scheme is adopted, in which spring three is fixedly connected between the upper end of the rubber block and the inner cavity of the shell three, so that the elastic force of the spring three can be used to push the lower end of the rubber block to always contact the upper end of the force-bearing plate, so that when the force-bearing plate is flipped and unfolded, it can reduce or even prevent the material from entering the inner cavity of the connecting block one from the upper gap position of the force-bearing plate, and the rubber block is slidably connected to the shell three, so that when the force-bearing plate adjusts the flipping angle, the rubber block will not block the flipping position of the upper end of the force-bearing plate, and can push the rubber block to slide in the inner cavity of the shell three, and adjust the position height of the rubber block in the inner cavity of the shell three.

[0022] A further improvement of the technical solution of the present invention is that a vibration pump is fixedly connected to one side of the lower part of the hopper bin, and a discharge block is fixedly connected to one side of the connecting rod close to the force plate, and the discharge block is arranged obliquely.

[0023] The above technical solution is adopted, in which a vibration pump is fixedly connected to the lower part of the hopper bin, so that the vibration generated by the vibration pump can be used to level the material in the inner cavity of the hopper bin, to prevent the end surface of the material in the inner cavity of the hopper bin from being uneven, with some places high and some places low, thereby affecting the monitoring result of the device. In addition, when the vibration pump is running, the vibration generated can drive the connecting rod to vibrate together, and then some materials that enter the inner cavity of the connecting block from the gap will move toward the direction of the discharge block under the action of the vibration. Since the discharge block is arranged at an angle, the material sliding out speed can be accelerated and the residence time of the material on the discharge block can be reduced.

[0024] The present invention also provides a loading hopper material level automatic monitoring system based on a loading building, comprising a control exchanger system, a lifting system, a material management system, a sensing system, a dust removal system, and a material conveying system. The control exchanger system is electrically connected to the lifting system, and the lifting system is used to control the operation of the cylinder and transmit the telescopic length data of the cylinder telescopic rod to the control exchanger system;

[0025] The control exchanger system is electrically connected to the whole material system, and the whole material system is used to control the operation of the vibration pump;

[0026] The control exchanger system is electrically connected to the sensing system, and the sensing system is used to transmit the data sensed by the pressure sensor to the control exchanger system, so that the data center can determine the material level in the inner cavity of the hopper bin;

[0027] The control exchanger system is electrically connected to the dust removal system, and the dust removal system is used to control the operation of the first push rod assembly, and the first push rod assembly is used to push the thrust block to move, and then the dust falling into the inner cavity of the connecting block can be pushed out through the thrust block;

[0028] The control exchanger system is electrically connected to the material conveying system, and the material conveying system is used to control the operation of the feed valve.

[0029] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0030] 1. The present invention provides an automatic monitoring device for the material level of a loading hopper based on a loading building. When it is necessary to monitor the material level of the loading hopper, the second push rod assembly is operated, so that the second push rod assembly can be used to drive the force-bearing plate to flip and unfold toward the side away from the first push rod assembly, and then the telescopic rod of the cylinder drives the connecting plate one to move upward. Since the connecting plate one is fixedly connected to the connecting rod one, when the connecting plate one moves, it will drive the connecting rod one to move upward together, and then the connecting rod one is used to drive the sensing component and the force-bearing rod to move upward together. Since the force-bearing rod penetrates the outer surface of the hopper bin and extends to the inner cavity of the hopper bin, when the force-bearing rod moves, it will drive the sensing component to enter the inner cavity of the hopper bin. When material is stored in the inner cavity of the hopper bin, during the movement of the sensing component, the material will apply a force to the force-bearing plate, driving the force-bearing plate to flip and shrink toward the direction of the first push rod assembly, and then When the force is applied, it will be transmitted to the force-bearing component, which can then be used to sense the force and then transmit the data to the data center; when the sensing component moves upward in the inner cavity of the hopper bin and the force-bearing plate is not subjected to external force, under the support of the second push rod assembly, the force-bearing plate will not exert force on the force-bearing component, and then the force-bearing plate transmits the data of not feeling the force to the data center, and the data center determines whether there is still material stored in the hopper by whether the force-bearing component senses the force. Therefore, the device can not only reduce or even avoid the error problem in the measurement result when monitoring the material in the inner cavity of the hopper bin, but also the data center can determine the position height of the material in the inner cavity of the hopper bin according to the contracted length of the cylinder telescopic rod, and control whether the lifting funnel transports the material into the inner cavity of the hopper bin through the data center, thereby improving the practicability and universality of the device.

[0031] 2. The present invention provides an automatic material level monitoring device for a loading hopper based on a loading building. The controller controls the electromagnet to cut off power, and then the electromagnet will release the magnetic attraction to the iron block. Then, under the elastic force of the second spring, the second spring will be driven to stretch, and then the iron block and the second docking rod will be pushed to move toward the direction of the force plate. Then, the second docking rod is used to drive the force plate to flip and unfold in the direction away from the first push rod assembly. When the force plate flips and unfolds, it is pulled by the second spring, so that the flipping angle of the force plate in the direction away from the first push rod assembly can be controlled to avoid the force plate flipping too large. Then, some materials enter the inner cavity of the connecting block from the gap, and then the position of the force plate is stuck, thereby affecting the normal use of the device.

[0032] 3. The present invention provides an automatic monitoring device for the material level of a loading hopper based on a loading building, wherein a vibration pump is fixedly connected to the lower part of the hopper bin, so that the vibration generated by the vibration pump can be used to level the material in the inner cavity of the hopper bin, to prevent the end surface of the material in the inner cavity of the hopper bin from being uneven, with some places being high and some places being low, thereby preventing the monitoring result of the device from affecting the monitoring result of the material level in the inner cavity of the hopper bin, thereby improving the monitoring result of the device on the material level in the inner cavity of the hopper bin. In addition, when the vibration pump is running, the vibration generated can drive the connecting rod to vibrate together, and then some materials that enter the inner cavity of the connecting block from the gap will move toward the direction of the discharging block under the action of the vibration. Since the discharging block is arranged at an angle, the sliding speed of the material can be accelerated and the residence time of the material on the discharging block can be reduced.

[0059] like Figure 5 As shown, based on Example 2, the present invention provides a technical solution: preferably, a vibration pump 2 is fixedly connected to one side of the lower part of the hopper bin 1, and a discharge block 41 is fixedly connected to one side of the connecting rod 4 close to the force plate 82, and the discharge block 41 is arranged at an angle.

[0060] In this embodiment, the cylinder 6 is then controlled to operate through the controller, and the telescopic rod of the cylinder 6 is used to drive the connecting plate 5 to rise together. When the connecting plate 5 rises, the connecting rod 4 is driven to rise together, and then the connecting rod 4 is used to drive the sensing component 8 to move upward. Since the connecting block 81 is fixedly connected to the force-bearing rod 9, when the sensing component 8 rises, the force-bearing rod 9 is driven to move upward together, and then the force-bearing rod 9 can be driven to move upward together. When the sensing component 8 moves, since materials are accumulated in the inner cavity of the hopper bin 1, these materials will apply force to the force-bearing plate 82, pushing the force-bearing plate 82 to move in the direction of the first push rod assembly 84, and then when the force-bearing plate 82 moves, it will apply force to the docking rod 864, and then drive the docking rod 864 to apply force to the adjacent spring 863, and then the spring 863 will apply force to the pressure sensor 862. The data center determines whether there is still material in the hopper by whether the pressure sensor 862 senses the force. Then, the data center determines the height of the material in the inner cavity of the hopper bin 1 according to the length of the contraction of the telescopic rod of the cylinder 6, and controls the lifting funnel to transport the material into the inner cavity of the hopper bin 1 through the data center. Since the flipping angle of the force plate 82 is fixed and the angle is small, the amount of material entering the inner cavity of the connecting block 81 through the gap can be reduced, and the material entering the inner cavity of the connecting block 81 will fall on the connecting rod 4. Since the connecting rod 4 is inclined, the material falling on the connecting rod 4 will be driven to slide down under the vibration force of the vibration pump 2, so as to avoid a large amount of material accumulating on the connecting rod 4 and then affecting the force plate 82.

[0061] Example 4

[0062] like Figure 8 , Fig. 9As shown, on the basis of Example 3, the present invention provides a technical solution: preferably, the first push rod assembly 84 includes an electric push rod 841, the electric push rod 841 is fixedly connected to the middle part of the inner cavity of the connecting block 1 81, the telescopic rod output end of the electric push rod 841 is fixedly connected to the connecting block 2 842, the middle part of the connecting block 2 842 is rotatably connected to the connecting block 3 843, the side of the connecting block 3 843 away from the electric push rod 841 is rotatably connected to the connecting block 4 844, the side of the connecting block 4 844 close to the thrust block 85 is fixedly connected to the thrust block 85, the thrust block 85 is symmetrically fixedly connected to the slider 851, the slider 851 is T-shaped, and the slider 851 on the same side is slidably connected to the limit block 83.

[0063] In this embodiment, when the monitoring of the material level in the inner cavity of the hopper bin 1 is completed and the force plate 82 needs to be reset, the first push rod assembly 84 is first controlled to operate through the controller, and the telescopic rod of the first push rod assembly 84 is used to push the connecting block 2 842 and the connecting block 3 843 to move. Then, when the connecting block 3 843 moves, it will drive the connecting block 4 844 to move. Then, the connecting block 4 844 is used to push the thrust block 85 toward the direction of the force plate 82, and then it can drive the slider 851 to slide in the inner cavity of the limit block 83. Then, when the thrust block 85 moves, it will move with the force assembly 86 and the second push rod assembly 87. Then, the force assembly 86 and the second push rod assembly 87 are used to drive the force plate 82 to further flip and unfold, expand the gap between the force plate 82 and the connecting block 1 81, and then use the thrust block 85 to push out the material that falls into the inner cavity of the connecting block 1 81, thereby completing the inner cavity of the connecting block 1 81. Clean, and then use the first push rod assembly 84 to operate, drive the thrust block 85 to reset, and then use the thrust block 85 to drive the force-bearing assembly 86 and the force-bearing assembly 86 to reset, so that the force-bearing plate 82 can be turned over and reset, and then the controller controls the electromagnet 872 to be energized, and then the electromagnet 872 will generate a magnetic force, and then the iron block 874 will be magnetically attracted, and then the iron block 874 will be driven to move toward the direction of the electromagnet 872, and then the docking rod 876 will be driven to move, so that the docking rod 876 can be used to drive the force-bearing plate 82 to further flip and reset, and then the pressure sensor 862 is controlled to stop running by the controller. When the force-bearing plate 82 is reset, the controller controls the cylinder 6 to operate, and the telescopic rod of the cylinder 6 is used to drive the connecting plate 5 to move downward, and then the connecting plate 5 drives the connecting rod 4 to move downward and reset, so that the connecting rod 4 can drive the sensing assembly 8 and the force-bearing rod 9 to reset.

[0064] like Fig.13As shown, the present invention also provides a loading hopper material level automatic monitoring system based on a loading building, including a control exchanger system, a lifting system, a material management system, a sensing system, a dust removal system, and a material conveying system. The control exchanger system is electrically connected to the lifting system, and the lifting system is used to control the operation of the cylinder 6 and transmit the telescopic length data of the telescopic rod of the cylinder 6 to the control exchanger system;

[0065] The control exchanger system is electrically connected to the material management system, and the material management system is used to control the operation of the vibration pump 2;

[0066] The control exchanger system is electrically connected to the sensing system, and the sensing system is used to transmit the data sensed by the pressure sensor 862 to the control exchanger system, so that the data center can determine the material level in the inner cavity of the hopper bin 1;

[0067] The control exchanger system is electrically connected to the dust removal system, and the dust removal system is used to control the operation of the first push rod assembly 84, and the first push rod assembly 84 is used to push the thrust block 85 to move, and then the dust falling into the inner cavity of the connecting block 81 can be pushed out through the thrust block 85;

[0068] The control exchanger system is electrically connected to the material delivery system, and the material delivery system is used to control the operation of the feed valve 3.

[0069] The working principle of the automatic monitoring device for material level in the loading hopper based on the loading building and its monitoring system is described in detail below.

[0070] like Figure 1 - Fig.13 As shown, when it is necessary to monitor the material level in the inner cavity of the hopper bin 1, the controller is first used to control the vibration pump 2 to run, and the vibration pump 2 is used to generate vibration, and then the material in the inner cavity of the hopper bin 1 is driven to slide, and then the end surface of the material in the inner cavity of the hopper bin 1 can be leveled to avoid excessive accumulation of material in some parts of the inner cavity of the hopper bin 1, and too little material in other parts, which will affect the monitoring result of the device. Then, the controller controls the electromagnet 872 to cut off the power, and then under the elastic force of the spring 873, the iron block 874 and the docking rod 876 are pushed to move together. Then, when the docking rod 876 moves, it pushes the force plate 82 to flip and unfold. When the force plate 82 flips and unfolds, when the force plate 82 flips, it applies force to the adjacent rubber block 912, driving the rubber block 912 to slide upward in the inner cavity of the shell 3 911, and then driving the spring 3 913 to contract. Since the force plate 82 is fixedly connected to the docking rod 864, it drives the docking rod 864 to move together, and then the docking rod 864 can drive the spring 863 to extend, and then the pressure sensor 862 is controlled to operate through the controller;

[0071] Then, the cylinder 6 is controlled to operate through the controller, and the telescopic rod of the cylinder 6 is used to drive the connecting plate 5 to rise together. When the connecting plate 5 rises, it will drive the connecting rod 4 to rise together, and then the connecting rod 4 is used to drive the sensing component 8 to move upward. Since the connecting block 81 is fixedly connected to the force-bearing rod 9, when the sensing component 8 rises, it will drive the force-bearing rod 9 to move upward together, and then it can drive the force-bearing rod 9 to move upward together. When the sensing component 8 moves, since materials are accumulated in the inner cavity of the hopper bin 1, these materials will apply force to the force-bearing plate 82, pushing the force-bearing plate 82 to move in the direction of the first push rod assembly 84, and then when the force-bearing plate 82 moves, it will apply force to the docking rod 864, and then drive the docking rod 864 to apply force to the adjacent spring 863, and then the spring 863 will apply force to the pressure sensor 862. Therefore, the pressure sensor 862 can sense the pressure and then transmit the data to the data center. The data center determines whether there is still material stored in the hopper by whether the pressure sensor 862 senses the force. Then, the data center can determine the position height of the material in the inner cavity of the hopper bin 1 according to the length of the contraction of the telescopic rod of the cylinder 6, and control the lifting funnel through the data center to transport the material into the inner cavity of the hopper bin 1. Since the flipping angle of the force plate 82 is fixed and the angle is small, the amount of material entering the inner cavity of the connecting block 81 through the gap can be reduced, and the material entering the inner cavity of the connecting block 81 will fall on the connecting rod 4. Since the connecting rod 4 is inclined, the material falling on the connecting rod 4 will be driven to slide down under the vibration force of the vibration pump 2, thereby avoiding a large amount of material from accumulating on the connecting rod 4 and then affecting the force plate 82.

[0072] After the monitoring of the material level in the inner cavity of the hopper bin 1 is completed, when the force plate 82 needs to be reset, the first push rod assembly 84 is first controlled by the controller to operate, and the telescopic rod of the first push rod assembly 84 is used to push the connecting block 2 842 and the connecting block 3 843 to move. Then, when the connecting block 3 843 moves, it will drive the connecting block 4 844 to move. Then, the connecting block 4 844 is used to push the thrust block 85 to move in the direction of the force plate 82, and then it can drive the slider 851 to slide in the inner cavity of the limit block 83. Then, when the thrust block 85 moves, it will move with the force assembly 86 and the second push rod assembly 87. Then, the force assembly 86 and the second push rod assembly 87 are used to drive the force plate 82 to further flip and unfold, expand the gap between the force plate 82 and the connecting block 1 81, and then use the thrust block 85 to push out the material that has fallen into the inner cavity of the connecting block 1 81, thereby completing the cleaning of the inner cavity of the connecting block 1 81. Then, the first push rod assembly 84 is used to operate to drive the thrust block 85 to reset, and then the thrust block 85 is used to drive the force-bearing assembly 86 and the force-bearing assembly 86 to reset, so that the force-bearing plate 82 can be turned over and reset, and then the electromagnet 872 is controlled by the controller to be energized, and then the electromagnet 872 will generate a magnetic force, and then the iron block 874 is magnetically attracted, and then the iron block 874 is driven to move toward the direction of the electromagnet 872, and then the docking rod 2 876 is driven to move, so that the docking rod 2 876 can be used to drive the force-bearing plate 82 to further flip and reset, and then the pressure sensor 862 is controlled to stop running by the controller. When the force-bearing plate 82 is reset, the cylinder 6 is controlled to operate by the controller, and the telescopic rod of the cylinder 6 is used to drive the connecting plate 5 to move downward, and then the connecting plate 5 drives the connecting rod 4 to move downward and reset, so that the sensing assembly 8 and the force-bearing rod 9 can be reset through the connecting rod 4.

[0073] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
