Description
Technical Field
[0001] This utility model relates to the technical field of port bulk cargo conveying devices, and in particular to a port bulk cargo conveying device with anti-blocking function. Background Technology
[0002] Port bulk cargo refers to unpackaged granular or powdery commodities that are loaded, unloaded and transported at ports, such as coal, iron ore, grain, sand and gravel, and fertilizer. Due to their large volume and weight, these goods are usually stored in bulk in the cargo holds of ships or piled in designated areas of the port, and are loaded and unloaded through specialized bulk cargo conveying equipment.
[0003] Traditional conveying devices often suffer from frequent blockages at the feed hopper, conveyor belt, or discharge port when handling viscous or highly humid bulk materials due to the lack of effective cleaning mechanisms. This not only reduces conveying efficiency but also makes it easy for bulk materials to adhere to the conveyor belt and the inner wall of the device during transport. Because traditional devices lack efficient cleaning mechanisms, cleaning becomes both difficult and time-consuming. In addition, these devices often rely on manual intervention to handle blockages and clean them, resulting in a low degree of automation and a significant increase in the labor intensity of operators.
[0004] Therefore, those skilled in the art have provided a port bulk cargo conveying device with anti-blockage function to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a port bulk cargo conveying device with anti-blockage function. Through the combined use of a vibrating motor and a return spring, the device achieves vibration and buffering of the discharge box, effectively loosening the material and preventing blockages. A scraper driven by a first servo motor automatically cleans the inner wall, keeping the discharge box unobstructed. Simultaneously, a gear transmission system driven by a second servo motor, including a driving gear, multiple driven gears, and a meshing toothed belt, ensures the synchronous movement of the brush mechanism, efficiently cleaning the material on the conveyor belt surface, preventing accumulation and wear, thereby reducing maintenance and replacement costs and improving the overall operating efficiency and reliability of the conveying device.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A port bulk cargo conveying device with anti-blocking function includes two fixed plates, a conveying mechanism, and a discharge box. The outer walls of the conveying mechanism are rotatably fitted to the lower outer walls of the adjacent sides of the fixed plates on both sides. A support frame is provided at the upper rear end of the conveying mechanism. The discharge box is located at the middle of the upper end of the support frame. A vibration motor is fixedly connected to the upper outer wall of the discharge box. Multiple sliding grooves are formed on the inner wall of the middle upper part of the support frame. Multiple fixed rods are fixedly connected to the lower outer wall of the discharge box. The outer wall of each fixed rod away from the center of the discharge box slides against the inner wall of the sliding groove. Multiple return springs are fixedly connected to the lower outer wall of the discharge box. One side of the material box, away from the center, is fixedly connected to the inner wall of the upper middle part of the support frame. The discharge port at the lower end of the material box is located at the upper part of the rear end of the conveying mechanism. An electric telescopic rod is fixedly connected to the middle part of one side of the upper surface of the support frame. The output end of the electric telescopic rod is fixedly connected to a support rod. A protective shell is provided at the middle part of the upper end of the material box. The lower end of the other side of the support rod is fixedly connected to the middle part of the upper surface of the protective shell. A first servo motor is provided inside the protective shell. The output end of the first servo motor passes through the protective shell to the lower end of the protective shell and is fixedly connected to a rotating rod. A scraper is tightly fitted to the inner wall of the material box. The lower end of the rotating rod is fixedly connected to the middle part of the upper surface of the scraper.
[0008] Through the above technical solution, the sliding contact design of the vibrating motor, fixed rod and sliding groove can vibrate the feeding box to help loosen the material and prevent the material from blocking at the discharge port. The setting of the return spring can provide a buffering effect. When the feeding box is impacted by the material and vibrated by the vibrating motor, the spring can absorb some energy and help the feeding box return to its original position after the impact. In addition, the connection between the scraper and the rotating rod can clean the material on the inner wall of the feeding box and prevent the material from adhering and accumulating. The setting of the first servo motor can realize the automatic cleaning and anti-blocking operation of the scraper.
[0009] Furthermore, an installation groove is formed on the inner wall of the lower end of the other side of the fixed plate on one side. A second servo motor is fixedly connected to the outer wall of the lower part of the front end of the fixed plate on one side. The output end of the second servo motor passes through the fixed plate to the other side of the fixed plate and is fixedly connected to a drive gear. A first connecting rod is fixedly connected to the inner wall of the drive gear. A first brush mechanism is fixedly connected to the outer wall of the other side of the first connecting rod. A first driven gear is provided at the rear end of the drive gear. A second driven gear is provided on the other side of the first driven gear. The inner walls of the first driven gear and the second driven gear are fixedly connected. A second connecting rod is fixedly connected to the first driven gear, and a second brush mechanism is fixedly connected to the outer wall of the other side of the second connecting rod. The outer wall gears of the driving gear and the first driven gear mesh with a first toothed belt. A third driven gear is provided at the rear end of the second driven gear. A third connecting rod is fixedly connected to the inner wall of the third driven gear. A third brush mechanism is fixedly connected to the outer wall of the other side of the third connecting rod. The outer wall gears of the second driven gear and the third driven gear mesh with a second toothed belt. The upper ends of the first brush mechanism, the second brush mechanism and the third brush mechanism are all rotatably attached to the outer wall of the lower end of the conveying mechanism.
[0010] The above technical solution provides a convenient installation method through the mounting slot, allowing the second servo motor and other components to be stably mounted on the fixed plate. The second servo motor drives the drive gear, which, combined with the first driven gear, the second driven gear, the third driven gear, and the first and second toothed belts meshing with them, forms a gear transmission system. This ensures the synchronous movement of multiple brush mechanisms, improving cleaning efficiency. The design of the brush mechanism helps to clean the material on the conveyor belt surface and prevents material accumulation. The gear transmission system ensures the synchronous movement of all brush mechanisms, improving the uniformity and efficiency of cleaning. Regular cleaning of the conveyor belt reduces maintenance and replacement costs caused by material accumulation and wear.
[0011] Furthermore, baffles are fixedly connected to the outer walls of the adjacent two sides of the rear end of the fixed plate, and the lower end of the baffles slides against the upper surface of the rear end of the conveying mechanism.
[0012] The above technical solution can prevent materials from falling off the rear end of the conveyor belt during the conveying process by using baffles.
[0013] Furthermore, an inclined plate is fixedly connected to the outer wall of the front end of the fixed plate, and the outer wall of the middle rear end of the inclined plate is slidably attached to the outer wall of the front end of the conveying mechanism;
[0014] The above technical solution uses an inclined plate as a material guide to help bulk materials fall smoothly from the conveyor belt into the collection mechanism.
[0015] Furthermore, a PLC control panel is fixedly connected to the outer wall on the other side of the support frame;
[0016] The above technical solution uses a PLC control panel to control the operation of the entire conveying device.
[0017] Furthermore, the outer walls of the adjacent two sides at the lower end of the support frame are in close contact with the outer wall of the fixed plate on the side away from the center of the conveying mechanism;
[0018] The above technical solution, through a close fit design, can enhance the connection stability between the support frame and the fixed plate, making the entire conveying device more stable during operation and reducing vibration and shaking.
[0019] Furthermore, the upper end of the first servo motor is fixedly connected to the inner top surface of the protective shell;
[0020] The above technical solution uses a protective shell to protect the internal first servo motor from damage by external factors.
[0021] Furthermore, the outer walls of the first brush mechanism, the second brush mechanism, and the third brush mechanism are all rotatably fitted with the outer walls of the lower ends of the adjacent sides of the fixed plate.
[0022] The above technical solution, through the rotating and fitting design, makes the multiple brush mechanisms more stable.
[0023] This utility model has the following beneficial effects:

The operation of the entire conveying device is controlled by the PLC control panel 301 to ensure the automation and stability of the conveying process. The inclined plate 102 can be used as a material guide device to help the bulk material slide smoothly from the conveyor belt into the collection mechanism. The tight fit design between the support frame 3 and the fixed plate 1 enhances the stability of the entire device and reduces vibration and shaking during operation.
