Description

Technical Field

[0001] This application relates to the field of mechanical design and manufacturing technology, and in particular to a belt feeder device. Background Technology

[0002] Coal washing plants typically use conveyor belts to transport coal slurry and unload it onto a slurry disposal area. The coal slurry falls freely from the conveyor belt discharge chute, which is 15 meters above the ground. Because the discharge chute is open, drafts frequently occur. In summer, these drafts cause dust to accumulate in the conveyor belt corridor, while in winter, cold drafts can lead to low temperatures, causing heating and fire ducts to freeze and crack. Low temperatures can even cause equipment lubricants to become viscous, making startup difficult and causing other production problems. Currently, cotton blankets are used to temporarily block and seal the discharge chute to prevent drafts. However, this increases the workload for workers, and if the sealing is not done properly or is forgotten, drafts can return to the conveyor belt corridor. Utility Model Content

[0043] like Figures 1-5 As shown, a conveyor belt unloading device in one embodiment of this application includes an unloading trough 1 for receiving materials falling from the conveyor belt 8 and having a unloading port 11, a flipping baffle 2 for covering the unloading port 11, and a flipping drive mechanism 3 for driving the flipping baffle 2 to flip open and close.

[0044] The tilting drive mechanism 3 is connected between the wall of the feeding trough 1 and the tilting baffle 2;

[0045] A trigger plate 4 that can be rotated by the material pressing down is hinged to one side wall of the feeding trough 1. The trigger plate 4 is located above the feeding port 11. An elastic reset member 5 is connected between the trigger plate 4 and the trough wall to keep the trigger plate 4 in a horizontal state.

[0046] The wall of the feeding trough 1 and / or the trigger plate 4 are equipped with a monitoring module for monitoring the rotation angle or tilt angle of the trigger plate 4;

[0047] When the trigger plate 4 is in the initial state, the trigger plate 4 extends horizontally in the feeding trough 1, the flipping drive mechanism 3 is in the initial state, and the flipping baffle 2 is in the closed state.

[0048] When the trigger plate 4 is tilted downwards, the flip drive mechanism 3 is in operation and the flip wind deflector 2 is in the open state.

[0049] In this embodiment, the belt feeding trough device includes a feeding trough 1 for receiving materials falling from the conveyor belt 8 and having a feeding port 11, a flipping baffle 2 for covering the feeding port 11, and a flipping drive mechanism 3 for driving the flipping baffle 2 to flip open and close, wherein the flipping drive mechanism 3 is connected between the trough wall of the feeding trough 1 and the flipping baffle 2.

[0050] A trigger plate 4 is hinged to one side wall of the feeding trough 1. The trigger plate 4 can be rotated by the material pressing down. The trigger plate 4 is located above the feeding port 11. An elastic reset member 5 is connected between the trigger plate 4 and the trough wall. The elastic reset member 5 can keep the trigger plate 4 in a horizontal state. When the material falls from the feeding port 11, part of it will fall on the trigger plate 4. At this time, the trigger plate 4 is pressed down. After the material leaves, the trigger plate 4 is reset by the elastic reset member 5 and returns to the initial state.

[0051] The wall of the feeding trough 1 and / or the trigger plate 4 are equipped with a monitoring module for monitoring the rotation angle or tilt angle of the trigger plate 4;

[0052] When the trigger plate 4 is in the initial state, the trigger plate 4 extends horizontally in the feeding trough 1, and the flipping drive mechanism 3 is in the initial state, while the flipping baffle 2 is in the closed state.

[0053] When the trigger plate 4 is tilted downwards, the flip drive mechanism 3 is in operation and the flip wind deflector 2 is in the open state.

[0054] Specifically, the monitoring module can be selectively located on the wall of the feeding trough 1, on the trigger plate 4, or simultaneously on both the wall of the feeding trough 1 and the trigger plate 4, or between the wall of the feeding trough 1 and the trigger plate 4. The monitoring module can employ electronic components such as angle sensors, rotation sensors, distance sensors, and cameras that can monitor the swing / rotation amplitude and state of the trigger plate 4, thereby enabling the monitoring of the rotation angle or tilt angle of the trigger plate 4.

[0055] The belt feeder device has a control unit, a tilting drive mechanism 3, and a monitoring module that are connected to the control unit by signals. When the monitoring module detects that the trigger plate 4 is tilted downwards, and its downward angle is α, or its downward tilt angle is 90-α, the monitoring module sends a signal to the control unit. The control unit then controls the tilting drive mechanism 3 to drive the tilting baffle 2 to rotate to open the feed port 11, so that the material can fall smoothly.

[0056] When the material slides off the trigger plate 4, the trigger plate 4 will be reset by the elastic reset member 5, thus returning to the initial state, that is, the trigger plate 4 is in a horizontal state in the feeding trough 1. When the monitoring module detects that the trigger plate 4 is in the initial state, it will send a signal to the control unit. The control unit will then control the flipping drive mechanism 3 to drive the flipping baffle 2 to reset and close the feeding port.

[0057] The pressure of falling material causes the trigger plate 4 to tilt and rotate downwards. The monitoring module monitors the changes in rotation angle / tilt angle in real time, which can accurately determine the falling state of the material. The flipping drive mechanism 3 automatically controls the opening and closing of the flipping baffle 2 according to the state of the trigger plate 4, without the need for manual intervention, thus realizing fully automatic feeding control.

[0058] like Figure 1 , Figure 2 As shown, in one embodiment, the elastic reset member 5 includes a torsion spring 51 or an elastic sheet.

[0059] In this embodiment, a trigger plate 4 that can be rotated by being pressed down by the material is hinged to one side wall of the feeding trough 1. That is, the feeding trough 1 and the trigger plate 4 can be connected by a hinge, the hinge including a hinge shaft, and an elastic reset member 5 is connected between the trigger plate 4 and the trough wall. The elastic reset member 5 includes a torsion spring 51 or an elastic sheet, which automatically resets the trigger plate 4 after it is pressed and tilted.

[0060] When the torsion spring 51 is used as an elastic reset element, the torsion spring 51 is sleeved on the hinge shaft, one end is fixed to the groove wall as a fixed end, and the other end is fixed to the trigger plate 4 as a rotating end. The reset torque of the torsion spring 51 is set by adjusting the preload angle, so that the trigger plate 4 can tilt downward when subjected to the falling pressure from the material, and can be reset to the initial state under the action of the torsion spring 51 after the material leaves.

[0061] When an elastic sheet is used as an elastic reset component, one end of the elastic sheet is fixed to the groove wall and the other end is connected to the trigger plate 4. The elastic deformation of the elastic sheet is used to realize the rotation and rebound of the trigger plate. The structure is more compact and the installation is more flexible. It is suitable for small spaces or dusty environments, further improving the versatility of the device.

[0062] In one embodiment, the monitoring module includes a rotation sensor and / or a tilt sensor.

[0063] In this embodiment, the monitoring module may include a rotation angle sensor or a tilt angle sensor, or a combination of a rotation angle sensor and a tilt angle sensor.

[0064] The angle sensor can be a potentiometer-type angle sensor, a photoelectric angle sensor, a Hall sensor, etc. The angle sensor can be set at the hinge between the feed trough 1 and the trigger plate 4, for example, installed on the rotating shaft of the trigger plate 4, to determine whether the trigger plate 4 is pressed down and the angle of its pressing down.

[0065] The tilt sensor can be an inductive tilt sensor, a fiber optic tilt sensor, a gyroscope, etc. The tilt sensor can be set on the trigger plate 4, or part of it can be set on the trigger plate 4 and the other part can be set on the wall of the feeding trough 1. It is used to monitor the tilt angle relative to the direction of gravity. The tilt sensor has a more compact structure and does not need to be installed with the rotating shaft, making it suitable for situations with limited assembly space.

[0066] When the monitoring module includes a combination of rotation angle sensor and tilt angle sensor, it can perform dual monitoring of the attitude of trigger plate 4 and the rotation angle of hinge structure, improving data accuracy and anti-interference ability, ensuring that the process monitoring of material pressing trigger plate 4 is more stable and less prone to false triggering.

[0067] In one preferred embodiment, the corner sensor includes a Hall sensor and a magnetic element. The Hall sensor is disposed on the wall of the feeding trough 1 and faces the trigger plate 4, and the magnetic element is disposed on the trigger plate 4.

[0068] In one preferred embodiment, the monitoring module includes a Hall sensor and a magnetic element. The Hall sensor is a magnetic induction element, which is disposed on the wall of the feeding trough 1 and faces the trigger plate 4. The magnetic element is disposed on the trigger plate 4. The Hall sensor can be installed above or below the hinge point between the trigger plate 4 and the trough wall and kept fixed. The tilting movement of the trigger plate 4 will not affect the position and orientation of the Hall sensor. The south pole of the magnetic element is facing the Hall sensor. When the trigger plate 4 tilts downward / upward, the magnetic element will rotate around the hinge axis with the trigger plate 4. Its south pole will be horizontally or vertically displaced relative to the Hall sensor, resulting in a change in the direction / intensity of the magnetic field. At this time, the voltage of the Hall sensor changes. After the control unit detects the voltage change of the Hall sensor, it will send an electrical signal to the flipping drive mechanism 3, so that the flipping drive mechanism 3 controls the flipping baffle 2 to change its state.

[0069] The non-contact monitoring of the Hall sensor and magnetic element enables the monitoring of the tilting motion of the trigger plate 4, making the tilting drive mechanism 3 move the tilting baffle 2 more quickly and having higher anti-interference ability and sensitivity.

[0070] In one embodiment, a Hall sensor is embedded in the wall of the feed trough 1, and a magnetic element is embedded inside the trigger plate 4.

[0071] In this embodiment, the embedded installation of the Hall sensor and the magnetic element saves space and is less susceptible to wear from materials, thus extending its service life.

[0072] In another embodiment, the Hall sensor is disposed at the hinge between the wall of the feed trough 1 and the trigger plate 4 and faces the trigger plate 4, and the magnetic element is disposed inside the trigger plate 4.

[0073] In this embodiment, the Hall sensor is placed in the gap at the hinge, and the magnetic element is placed inside the trigger plate 4. This improves the compactness of the overall structure, saves space, reduces the exposed part of the monitoring module, reduces the wear of the monitoring module when materials fall on the trigger plate 4, reduces interference, improves monitoring stability, and is more suitable for dusty and humid environments.

[0074] In one embodiment, a magnetic element is disposed on the wall of the feeding trough 1 and faces the trigger plate 4, and a Hall sensor is disposed on the trigger plate 4 and faces the magnetic element.

[0075] In this embodiment, the Hall sensor is mounted on the swinging trigger plate 4, while the magnetic element is fixed on the wall of the feeding trough 1. Once the trigger plate 4 swings, the change in magnetic field will be immediately sensed by the Hall sensor, resulting in a fast signal response and more sensitive monitoring.

[0076] The magnetic element is fixed to the stationary tank wall for stable installation, while the Hall sensor is set on the movable trigger plate 4. The wiring can be arranged in a centralized manner, which is conducive to modular design and makes it easy for technicians to install and maintain.

[0077] Specifically, technicians can set an angle threshold for the tilt or rotation angle of the trigger plate 4. The voltage corresponding to this angle threshold is compared with the voltage corresponding to the initial angle as the triggering criterion. When the trigger plate 4 tilts from the initial state to this angle threshold, taking a Hall sensor as an example, the position of the magnetic element relative to the Hall sensor changes, causing the output voltage of the Hall sensor to change accordingly. When this voltage reaches the set threshold voltage, the control unit recognizes that the trigger plate 4 has reached the preset tilt angle threshold. At this time, the Hall sensor sends a signal to the control unit, triggering the flip drive mechanism 3 to operate, thereby driving the flip baffle 2 to open / close.

[0078] In another embodiment, the monitoring module includes an angle sensor, which is a potentiometer-type angle sensor. The potentiometer-type angle sensor drives its sliding contact to slide on the surface of the resistive material through a rotating shaft, thereby outputting a voltage signal that changes with the angle. The position of its sliding on the resistive material has an approximately linear relationship with the voltage, which can realize real-time monitoring of the rotation angle.

[0079] In this embodiment, the fixed end of the potentiometer-type angle sensor is installed on the wall of the feeding trough 1. The rotation axis of the potentiometer-type angle sensor is fixedly connected to the hinge axis of the trigger plate 4. When the trigger plate 4 rotates around the hinge axis, it drives the rotation axis of the potentiometer-type angle sensor to rotate synchronously, thereby driving the sliding contact inside the potentiometer to displace, thus causing a voltage change in the potentiometer-type angle sensor. After the control unit detects that the voltage change has reached a preset voltage threshold, it can identify that the trigger plate 4 has reached the set rotation angle, thereby determining that the material has started to fall, triggering the flipping drive mechanism 3 to operate, thereby driving the flipping baffle 2 to open / close. The potentiometer-type angle sensor has a simple structure, low cost, and is easy to maintain and replace, making it suitable for industrial applications.

[0080] In another embodiment, the monitoring module includes a laser ranging angle sensor, which is fixedly mounted on the wall of the feeding trough 1 and aligned with a specific measurement point on the trigger plate 4. The specific measurement point can be on the upper or lower surface of the trigger plate 4. After the laser from the laser ranging angle sensor hits the specific measurement point on the surface of the trigger plate 4, it will bounce back through diffuse reflection. By calculating the time difference between transmission and reception or the change in the laser reflection angle, the displacement change of the trigger plate 4 during tilting or rotation can be measured, and the rotation angle or tilt angle of the trigger plate 4 can be further calculated.

[0081] When the trigger plate 4 tilts or rotates, a specific measuring point will shift with the change in the attitude of the trigger plate 4, causing the laser return time to change. The laser ranging angle sensor can measure the distance change at that point, and further calculate the rotation angle or tilt angle of the trigger plate 4 through geometric conversion. When the control unit detects that the rotation angle or tilt angle of the trigger plate 4 reaches a certain level, it can identify that the trigger plate 4 has reached the set angle threshold, thereby determining that the material has started to fall, triggering the flipping drive mechanism 3 to operate, thereby driving the flipping baffle 2 to open / close.

[0082] Laser ranging offers fast response and high measurement accuracy, along with strong anti-interference capabilities. It is suitable for applications with limited space, high dust levels, or where minimal interference is required on the trigger plate 4, thus improving the adaptability and monitoring stability of the device.

[0083] In another embodiment, the monitoring module includes a tilt sensor, which can be an inductive sensor, a fiber optic tilt sensor, a gyroscope, or a MEMS (microelectromechanical system) sensor, etc. The tilt sensor is set inside / on the surface of the trigger plate 4 and is used to monitor the tilt angle of the trigger plate 4 relative to the direction of gravity in real time. It can directly respond to changes in the direction of gravity and has good stability in dusty and vibrating environments.

[0084] In another embodiment, the monitoring module includes a tilt sensor, specifically a fiber optic tilt sensor. This fiber optic tilt sensor can calculate the tilt angle by monitoring changes in output light intensity or the reflected wavelength of a fiber optic grating. The fiber optic tilt sensor is located inside / on the surface of the trigger plate 4, and achieves real-time measurement of the tilt angle of the trigger plate 4 by monitoring changes in light intensity or wavelength in the fiber. The fiber optic tilt sensor has strong anti-electromagnetic interference capabilities and a fast response speed, making it suitable for environments with high dust levels, severe electromagnetic interference, and explosive potential.

[0085] In one preferred embodiment, the monitoring module includes a rotation angle sensor and a tilt angle sensor. The rotation angle sensor includes a Hall sensor and a magnetic element, and the tilt angle sensor is a MEMS (Micro-Electro-Mechanical System) sensor. The Hall sensor is disposed on one side wall of the feeding trough 1 and near the hinge between the feeding trough 1 and the trigger plate 4. The Hall sensor can be installed above or below the hinge between the feeding trough 1 and the trigger plate 4 and facing the trigger plate. The magnetic element is fixedly installed on the inner side of the trigger plate 4 near the hinge axis or on the bottom of the trigger plate 4, with its south pole facing the Hall sensor, to generate a change in magnetic field when the trigger plate 4 rotates. The MEMS sensor is embedded inside or on the surface of the trigger plate 4, with the mounting surface maintaining a horizontal relationship with the trigger plate 4, to monitor the change in the tilt angle of the trigger plate 4 in the direction of gravity in real time.

[0086] Specifically, the rotation sensor composed of Hall effect sensors and magnetic elements monitors the angular displacement of the trigger plate 4 at the hinge axis in real time, with fast response, flexible installation and compact structure; while the tilt sensor composed of MEMS microelectromechanical sensors monitors the overall tilt angle of the trigger plate 4, with the advantages of high sensitivity and high anti-interference. The combination of the two achieves dual monitoring of the rotation angle and tilt angle of the trigger plate 4, which improves the adaptability of the device under different working conditions. When either sensor fails or has a large error, the other sensor can compensate for the monitoring, which enhances the stability of the device.

[0087] like Figures 2-5 As shown, in another embodiment, the flipping drive mechanism 3 includes a rotating shaft 31 pivotally connected to the wall of the feeding trough 1, an electric module 32 for driving the rotating shaft 31 to rotate, a first connecting rod 33 fixedly connected to the rotating shaft 31, and a second connecting rod 34 hinged to the first connecting rod 33. The electric module 32 is signal-connected to the monitoring module.

[0088] One end of the second link 34 is hinged to the flip-up windshield 2.

[0089] In this embodiment, the flipping drive mechanism 3 includes a rotating shaft 31, an electric module 32, a first connecting rod 33, and a second connecting rod 34. The rotating shaft 31 is pivotally connected to the wall of the feeding trough 1. The wall can be the inner wall or the outer wall of the feeding trough 1, preferably the outer wall, because setting it on the outer wall can avoid the influence of material dust.

[0090] The electric module 32 is used to drive the rotating shaft 31 to rotate and is connected to the monitoring module for signal transmission. When the trigger plate 4 tilts up / down, the monitoring module sends an electrical signal to the electric module 32. After receiving the signal from the monitoring module, the electric module 32 controls the rotating shaft 31 to rotate. The rotating shaft 31 is fixedly connected to one end of the first connecting rod 33, which drives the first connecting rod 33 to rotate. The other end of the first connecting rod 33 is hinged to the second connecting rod 34, which transmits power to the second connecting rod 34. The other end of the second connecting rod 34 is hinged to the flip-up wind deflector 2, thereby driving the flip-up wind deflector 2 to open / close.

[0091] The hinged transmission of the first link 33 and the second link 34 converts the rotational motion output by the electric module 32 to the rotating shaft 31 into the opening and closing motion of the flip wind deflector 2, amplifying the torque so that it can drive the large-sized flip wind deflector 2 with less power.

[0092] In one embodiment, the flipping drive mechanism 3 includes two first connecting rods 33 and two second connecting rods 34. The two ends of the rotating shaft 31 are respectively connected to one end of the two first connecting rods 33, and the other ends of the two first connecting rods 33 are respectively connected to one end of the two second connecting rods 34. The other ends of the two second connecting rods 34 are hinged to the flipping wind deflector 2.

[0093] In this embodiment, each end of the rotating shaft 31 is connected to a set of connecting rods, namely the first connecting rod 33 and the second connecting rod 34, forming a double-sided symmetrical drive structure. This ensures that the force on the flip wind deflector 2 is evenly distributed on both sides, allowing it to maintain horizontal synchronous movement during opening / closing and avoiding jamming caused by uneven force.

[0094] like Figure 5 As shown, in one embodiment, two oppositely arranged mounting brackets 35 are provided on the outer surface of the feeding trough 1;

[0095] The electric module 32 is mounted on one of the mounting brackets 35, and the rotating shaft 31 is pivotally connected to both mounting brackets 35. One end of the rotating shaft 31 is connected to the output end of the electric module 32.

[0096] In this embodiment, the electric module 32 is mounted on one of the mounting brackets 35. Two oppositely arranged mounting brackets 35 are provided on the outer surface of the feeding trough 1. The rotating shaft 31 is pivotally connected to the two mounting brackets 35. One end of the rotating shaft 31 is connected to the output end of the electric module 32. The rotating shaft 31 is supported by the two mounting brackets 35 and connected to the electric module 32, so that the force is more evenly distributed. The mounting brackets 35 are installed on the outer surface of the feeding trough 1, that is, the rotating shaft 31 is also installed on the outside of the feeding trough 1. The first connecting rod 33 and the second connecting rod 34 are also set on the outside of the feeding trough 1. The entire flipping drive mechanism 3 is set on the outside of the feeding trough 1, which does not affect the internal space layout of the feeding trough 1. The material in the feeding trough 1 will not affect the flipping drive mechanism 3, and it is also convenient for future maintenance and improves maintenance efficiency.

[0097] like Figures 1-4 As shown, in another embodiment, the flip-up baffle 2 is connected to the edge of the feed port 11 via a hinge 6.

[0098] In this embodiment, the hinge 6 connects the flip-up wind baffle 2 to the edge of the feed port 11, allowing the wind baffle to flip around the axis of the hinge 6, thus opening or closing according to actual needs. This ensures long-term stable use, and the hinge 6 connection method does not require additional complex linking structures, resulting in high integration, easy replacement, and reduced maintenance costs.

[0099] like Figure 1 , Figure 2 As shown, in one embodiment, a first mudguard 7 extending downward at an angle is provided in the feed trough 1 above the hinge 6.

[0100] In this embodiment, a first mudguard 7 is inclined downward above the hinge 6 in the feeding trough 1. The first mudguard 7 extends downward from the trough wall of the feeding port 11, which can effectively block the materials and dust falling from the feeding trough 1, prevent them from accumulating at the hinge 6, reduce the risk of the hinge 6 getting stuck and corroded, and improve the service life of the flip-up wind baffle 2. In addition, the first mudguard 7 is inclined downward, which has a good guiding effect, naturally guiding the materials to the feeding area and ensuring the operational stability of the hinge 6.

[0101] like Figure 1 , Figure 2 As shown, in another embodiment, the feed trough 1 is provided with a belt scraper 9 for removing residual material from the conveyor belt 8;

[0102] The belt scraper 9 extends upward at an angle, and the upper end of the belt scraper 9 abuts against the lower surface of the conveyor belt 8.

[0103] In this embodiment, the belt feeding trough device also includes a conveyor belt 8 disposed above the feeding port 11. The conveyor belt 8 is used to transport materials to the feeding port 11. The trough wall of the feeding trough 1 is provided with a belt scraper 9 for removing residual materials on the conveyor belt 8. The upper end of the belt scraper 9 abuts against the lower surface of the conveyor belt 8, which can effectively scrape off the residual materials on the surface of the conveyor belt 8, avoid the accumulation of materials on the belt, thereby reducing the risk of unclean feeding and equipment contamination, reducing the frequency of manual intervention, improving the automation level of the equipment, reducing maintenance costs, and extending the service life of the conveyor belt 8.

[0104] In one embodiment, a sealing strip is provided at the discharge port 11;

[0105] When the flip-up wind deflector 2 is in the closed state, the sealing strip is in contact with the edge of the flip-up wind deflector 2.

[0106] In this embodiment, a sealing strip is provided at the discharge port 11. When the flip-up baffle 2 is in the closed state, the sealing strip fits against the edge of the flip-up baffle 2, which can effectively block the leakage of air, dust and particulate matter, and improve the sealing performance of the belt discharge chute device. At the same time, the sealing strip can also play a certain buffering role when the flip-up baffle 2 is closed, reducing the noise when metal materials collide and improving the quietness of the equipment during operation.

[0107] like Figure 1 , Figure 2 As shown, in another embodiment, a second mudguard 10 extending downward at an angle is provided in the feed trough above the sealing strip.

[0108] In this embodiment, a second mudguard 10 extending downward at an angle is provided above the sealing strip in the feeding trough. The shape of the second mudguard 10 is adapted to the shape of the trough wall of the feeding trough 1, which can effectively block the material falling from above, prevent it from accumulating directly on the sealing strip, reduce the risk of wear, contamination and aging of the sealing strip, improve its service life, and also prevent the sealing strip from being covered by foreign objects, ensuring that it can always fit well with the edge of the flip-up wind deflector 2, improve its sealing effect, and prevent air leakage, dust and other problems caused by sealing failure.

[0109] The second mudguard 10 has an inclined structure, which helps guide materials to slide naturally down its surface and be discharged from the equipment, reducing the frequency of cleaning by employees and improving the automation level of the equipment.

[0110] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0111] The above description is merely the principle and preferred embodiment of this application. It should be noted that for those skilled in the art, implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included within the technical scope of this invention. Based on the principle of this application, several other modifications can also be made, which should also be considered within the protection scope of this application.
