Abstract
Description
Technical Field
[0001] This application relates to the field of unloading equipment technology, and in particular to a follow-up variable material guiding structure. Background Technology
[0002] In the field of material storage and transportation, the stacker-reclaimers, material reclaimers, and ship unloaders commonly used equipment, after completing the material reclaiming or unloading operation, will have the material fall directly onto the ground conveyor belt, which will then transport the material to the steel plant or stockyard. Generally speaking, the ground conveyor belt adopts a unidirectional operation design mode, which can meet the production needs in most conventional processes. However, in actual production, in order to save costs or optimize the process, the ground conveyor belt is sometimes designed to operate in both directions.
[0003] When a ground conveyor belt needs to operate in both directions, the traditional fixed hopper structure cannot adapt to the new operating requirements. Since the direction in which the material falls is fixed, it cannot be consistent with the different directions of the ground conveyor belt's bidirectional operation. The running state of the material on the conveyor belt will be seriously affected, and the material is prone to deviation. This will not only reduce the efficiency of material conveying, but may also cause material spillage, resulting in resource waste and environmental pollution. Therefore, it needs to be improved. Utility Model Content
[0004] To address the issue that fixed hopper structures cannot meet operational requirements, this application provides a follow-up variable material guiding structure.
[0005] The following technical solution is adopted for the follower variable material guiding structure provided in this application:
[0006] A follow-up variable material guiding structure includes a guide hopper arranged below a feed hopper, a material guiding trough disposed below the guide hopper, the outlet end of the guide hopper inserted into the material guiding trough, a support disposed on one side of the guide hopper, a reversing mechanism disposed on the support, the reversing mechanism including an electro-hydraulic actuator, the guide hopper hinged to the support, the cylinder end of the electro-hydraulic actuator hinged to the support, the piston end of the electro-hydraulic actuator hinged to the guide hopper, the electro-hydraulic actuator driving the guide hopper to swing horizontally around the hinge point, and a traveling mechanism disposed at the bottom of the guide trough, the traveling mechanism driving the material guiding trough to move horizontally.
[0007] Traditional fixed hopper structures cannot adapt to new operational requirements. The fixed direction of material descent prevents alignment with the bidirectional movement of the ground conveyor belt, severely impacting material flow and leading to deviations. This not only reduces conveying efficiency but also causes spillage, resulting in resource waste and environmental pollution. Therefore, a dynamic, variable-direction material guiding structure is needed, including a guide hopper installed below the incoming hopper. The guide hopper's outlet is inserted into a guide trough, and the guide hopper is hinged to a support. The piston end of an electro-hydraulic actuator is hinged to the guide hopper, and the guide trough is equipped with a traveling mechanism. The combination of the guide hopper, guide trough, reversing mechanism, and traveling mechanism helps ensure the material's direction of travel aligns with the ground conveyor belt's direction, precisely matching the bidirectional movement of the conveyor belt. This effectively solves the problems of material deviation, dust generation, and conveying efficiency caused by the fixed descent direction of traditional fixed hoppers, ensuring stable material flow throughout the conveying process, effectively preventing resource loss and environmental pollution caused by spillage, and improving conveying efficiency.
[0008] Optionally, the bracket is provided with a guide rail parallel to the length of the belt conveyor, and the traveling mechanism is slidably connected to the guide rail.
[0009] By adopting the above technical solution, the guide rail is installed on the bracket, and the pulley block of the traveling mechanism and the guide rail form a sliding pair. Through the setting of the guide rail, the guide rail provides a stable running track for the traveling mechanism, ensuring that the traveling mechanism can move smoothly along the predetermined direction during horizontal displacement, effectively avoiding equipment shaking or misalignment caused by deviation of the motion trajectory, and ensuring operational reliability.
[0010] Optionally, the support is provided with a buffer device, which includes a plurality of buffer rollers arranged below the feed trough.
[0011] By adopting the above technical solution, the buffer device is installed on the bracket and includes several buffer rollers. The arrangement of several buffer rollers can disperse the impact force generated on the belt when the material falls, effectively reduce the risk of excessive local stress on the belt, reduce the wear and deformation of the belt caused by instantaneous impact, and extend the service life of the belt.
[0012] Optionally, a follow-up sealing device I is provided at the joint between the outer wall of the guide hopper and the top surface of the guide trough, and a follow-up sealing device II is provided at the joint between the inner wall of the guide trough and the side wall of the guide hopper.
[0013] By adopting the above technical solution, the follow-up sealing device I is installed at the joint between the outer wall of the guide hopper and the top surface of the guide trough, and the follow-up sealing device II is installed at the joint between the inner wall of the guide trough and the side wall of the guide hopper. With the setting of the follow-up sealing device I and the follow-up sealing device II, the dust overflow during the material conveying process can be effectively reduced, environmental pollution can be avoided, and external impurities can be reduced from entering the equipment, ensuring the cleanliness of the equipment.
[0014] Optionally, the upper part of the follow-up sealing device I is disposed on the outer wall of the guide hopper, and the lower part of the follow-up sealing device I slides in contact with the top of the guide trough to form a dynamic seal. The lower part of the follow-up sealing device II is disposed on the inner wall of the guide trough, and the upper part of the follow-up sealing device II slides in contact with the side wall of the guide hopper to form a dynamic seal.
[0015] By adopting the above technical solution, the upper part of the follow-up sealing device I is set on the outer wall of the guide hopper, and the lower part of the follow-up sealing device I slides in contact with the top of the guide trough to form a dynamic seal. The lower part of the follow-up sealing device II is set on the inner wall of the guide trough, and the upper part of the follow-up sealing device II slides in contact with the side wall of the guide hopper to form a dynamic seal. Through the arrangement, the sealing parts can always maintain effective contact when the guide hopper and the guide trough move relative to each other (such as the guide hopper rotating or the guide trough moving horizontally), effectively preventing dust generated during material conveying from escaping and avoiding dust pollution to the surrounding environment.
[0016] Optionally, a follow-up sealing door for sealing is provided at the joint between the guide hopper and the feed hopper.
[0017] By adopting the above technical solution, the follow-up sealing door is installed at the joint between the guide hopper and the incoming hopper; the setting of the follow-up sealing door further reduces the possibility of dust leakage from the joint during material conveying, avoids dust diffusion and pollution of the working environment, and protects the health of operators.
[0018] Optionally, the follow-up sealing door includes a sealing door panel and an electric push rod. The sealing door panel covers the joint gap, and the electric push rod is arranged on the guide hopper. The piston end of the electric push rod is hinged to the sealing door panel.
[0019] By adopting the above technical solution, the follow-up sealing door includes a sealing door panel and an electric push rod. With the setting of the sealing door panel and the electric push rod, the electric push rod can automatically drive the sealing door panel to open and close according to the operating status of the guide hopper, ensuring that the sealing door panel is always tightly fitted to the seam, effectively preventing dust from overflowing and avoiding environmental pollution.
[0020] Optionally, the follow-up sealing door also includes a limit switch, which is installed at the end of the swing path of the guide hopper.
[0021] By adopting the above technical solution, the follow-up sealing door also includes a limit switch. By setting the limit switch, the opening and closing stroke of the sealing door can be precisely controlled, ensuring that the sealing door always maintains an appropriate sealing position with the hopper during the rotation of the hopper, and avoiding the sealing effect from being affected by over-opening or incomplete closing.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting up guide hoppers, guide troughs, reversing mechanisms and traveling mechanisms, it helps to ensure that the material running direction is consistent with the running direction of the ground belt conveyor.

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0032] This application discloses a follower-type variable material guiding structure. (Refer to...) Figure 1 The following variable material guiding structure includes a guide hopper 2. In this embodiment, the guide hopper 2 is installed below the existing feed hopper 1. The outlet end of the feed hopper 1 corresponds to the top opening of the guide hopper 2. A guide trough 3 is installed below the guide hopper 2. The outlet end of the guide hopper 2 is inserted into the guide trough 3. The bottom of the guide trough 3 is directly opposite the belt conveyor.
[0033] Reference Figure 1 , Figure 3 and Figure 4 A bracket 4 is installed on one side of the guide hopper 2. The guide hopper 2 is hinged to the bracket 4. In this embodiment, the guide hopper 2 can be hinged to the bracket 4 through a hinge shaft. A reversing mechanism 5 is installed on the bracket 4. The reversing mechanism 5 is used to drive the guide hopper 2 to swing horizontally around the hinge shaft. The reversing mechanism 5 includes an electro-hydraulic push rod 51. The cylinder end of the electro-hydraulic push rod 51 is hinged to the bracket 4, and the piston end of the electro-hydraulic push rod 51 is hinged to the guide hopper 2. In this embodiment, the guide hopper 4 can be equipped with a hinge rod that is hinged to the electro-hydraulic push rod 51.
[0034] Reference Figure 1 A follow-up sealing door 11 is installed at the joint between the guide hopper 2 and the receiving hopper 1. The follow-up sealing door 11 includes a sealing door plate 111, an electric push rod 112 and a limit switch. The sealing door plate 111 covers the joint gap. The electric push rod 112 is arranged on the guide hopper 2. The piston end of the electric push rod 112 is hinged to the sealing door plate 111. This reduces the possibility of dust leakage from the joint during material conveying, avoids dust diffusion and pollution of the working environment, and protects the health of operators.
[0035] Reference Figure 1 The limit switch is installed at the end of the swing path of the guide hopper 2. In this embodiment, the limit switch is electrically connected to the electric push rod 112 to control the stroke of the sealing door 111. The limit switch can accurately control the opening and closing stroke of the sealing door to ensure that the sealing door always maintains an appropriate sealing position with the hopper during the rotation of the hopper, and avoids affecting the sealing effect due to excessive opening or incomplete closing.
[0036] Reference Figure 1 and Figure 2A traveling mechanism 6 is installed at the bottom of the guide trough 3. The traveling mechanism 6 drives the guide trough 3 to move horizontally. A guide rail 7 is installed parallel to the length of the belt conveyor on the bracket 4. The traveling mechanism 6 is slidably connected to the guide rail 7. The pulley group of the traveling mechanism 6 and the guide rail 7 form a sliding pair. In this embodiment, the traveling mechanism 6 can be equipped with a pulley group, driving components, etc. Through the setting of the guide rail 7, the guide rail 7 provides a stable running track for the traveling mechanism 6, ensuring that the traveling mechanism 6 can move smoothly along the predetermined direction during horizontal displacement, effectively avoiding equipment shaking or misalignment caused by deviation of the movement trajectory, and ensuring operational reliability.
[0037] Reference Figure 1 A follow-up sealing device I9 is installed at the joint between the outer wall of the guide hopper 2 and the top surface of the guide trough 3 for sealing, and a follow-up sealing device II10 is installed at the joint between the inner wall of the guide trough 3 and the side wall of the guide hopper 2 for sealing. There are multiple sets of follow-up sealing devices I9 and II10. In this embodiment, both follow-up sealing devices I9 and II10 are composed of sealing plates, sealing strips, pressure plates, clamping plates, and hand cranks. This can effectively reduce dust overflow during material conveying, avoid environmental pollution, and reduce the entry of external impurities into the equipment, ensuring the cleanliness of the equipment interior.
[0038] Reference Figure 1 The upper part of the follow-up sealing device I9 is installed on the outer wall of the guide hopper 2 and rotates with the guide hopper 2. The lower part of the follow-up sealing device I9 (equipped with a sealing strip) slides in contact with the top of the guide trough 3 to form a dynamic seal. The lower part of the follow-up sealing device II10 is installed on the inner wall of the guide trough 3. The upper part of the follow-up sealing device II10 (equipped with a sealing strip) slides in contact with the side wall of the guide hopper 2 to form a dynamic seal. At the same time, this structure is equipped with a control device 12, which consists of a traveling encoder, a traveling limit switch, an electro-hydraulic push rod 51 limit switch, a PLC, etc. It communicates with the control center through the PLC to ensure that the guide trough 3 and the guide hopper 2 move simultaneously, thereby achieving synchronous belt running direction and achieving the purpose of precise control.
[0039] Reference Figure 2 A buffer device 8 is installed on the bracket 4. The buffer device 8 includes several buffer rollers 81. The several buffer rollers 81 are arranged below the material guide trough 3. In this embodiment, the buffer rollers 81 are rotatably installed on the bracket 4 to disperse the impact force on the belt when the material falls, effectively reduce the risk of excessive local stress on the belt, reduce the wear and deformation of the belt caused by instantaneous impact, and extend the service life of the belt.
[0040] The implementation principle of the following variable guide structure in this application embodiment is as follows: When the ground conveyor belt runs forward, the material flow direction from the guide hopper 2 should also follow the conveyor belt forward. At this time, the electro-hydraulic push rod 51 of the reversing mechanism 5 retracts, driving the guide hopper 2 to rotate forward, so that the material falls onto the hopper wall. The hopper wall tilts forward, thereby changing the material flow direction from vertical downward movement to inclined forward movement, so that the material running direction is consistent with the ground conveyor belt running direction, reducing the impact of the material on the conveyor belt and preventing the conveyor belt from deviating. At the same time, when the guide hopper 2 rotates forward, the guide trough 3 is controlled by the control device 12. The traveling mechanism 6 is activated to ensure that the guide trough 3 and the guide hopper 2 move together, so that there is no large gap between the guide hopper 2 and the guide trough 3. At the same time, the follow-up sealing door 11 is activated to open and close the sealing door plate 111, ensuring that the gap between the upper material hopper and the guide hopper 2 is sealed by the sealing door to prevent dust from escaping. In addition, the follow-up sealing device I9 moves with the guide hopper 2 and slides on the guide trough 3 to ensure a tight fit. At the same time, the follow-up sealing device II10 moves with the guide trough 3 to prevent gaps from forming between the guide trough 3 and the guide hopper 2, which would allow dust to escape. This ensures that the material running direction is consistent with the running direction of the ground belt conveyor, and also ensures that the seal is sealed and dust does not escape.
[0041] When the ground conveyor belt runs backward, the material flow from the guide hopper 2 must also follow the belt belt backward. The electro-hydraulic push rod 51 of the reversing mechanism 5 extends forward, pushing the guide hopper 2 to rotate backward. This causes the material to fall onto the hopper wall, and the backward tilt of the hopper wall changes the material flow from vertical downward to a sloping flow, thus aligning the material's direction of movement with the backward direction of the ground conveyor belt. As the guide hopper 2 rotates backward, the guide trough 3 is activated by the control device 12 via the travel mechanism 6, ensuring that the guide trough 3 moves together with the guide hopper 2, allowing the guide material to flow smoothly. There is no large gap between the hopper 2 and the guide trough 3. At the same time, by activating the upper follow-up sealing door 11 to open and close the sealing door plate 111, the gap between the upper material hopper and the guide hopper 2 is sealed by the sealing door plate 111 to prevent dust from escaping. In addition, the follow-up sealing device I9 moves with the guide hopper 2 and slides on the guide trough 3 to ensure a tight fit. At the same time, the follow-up sealing device II10 moves with the guide trough 3 to prevent gaps from forming between the guide trough 3 and the side seal of the guide hopper 2, thus preventing dust from escaping. This ensures that the material running direction is consistent with the running direction of the ground belt conveyor, and also ensures sealing to prevent dust from escaping.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
