[0002] As a core material handling equipment, conveyors are widely used in various heavy-duty and high-capacity scenarios. Currently, existing conveyors generally suffer from problems such as poor cushioning effect and insufficient structural strength: when materials fall from a height and impact the conveyor belt, there is a lack of effective multi-stage cushioning mechanisms, and the impact force acts directly on the conveyor belt and frame, which can easily lead to local tearing and wear of the conveyor belt, and deformation and breakage of the frame; at the same time, the conveyor belt is prone to deviation during operation, which further aggravates equipment wear and reduces conveying efficiency; in addition, existing cushioning mechanisms are mostly external, which are inconvenient to install and maintain, and have poor cushioning stability, making them unsuitable for long-term high-intensity conveying conditions. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-segment buffer high-strength conveyor device to solve the problem of poor buffering effect in existing conveyor devices.

[0004] To achieve the above objectives, the present invention provides a multi-segment buffered high-strength conveyor device, including a conveying mechanism and a buffering mechanism.

[0018] Example Please see Figures 1-5 The present invention provides a multi-segment buffered high-strength conveyor device, including a conveying mechanism and a buffering mechanism. The buffering mechanism is set inside the conveying mechanism, and the buffering mechanism and the conveying mechanism work together to achieve stable and high-strength conveying of materials.

[0019] The conveying mechanism includes a frame 1, which is made of Q355B high-strength steel. Reinforcing ribs 27 are welded between the frame 1 sections, with spacing between them to enhance the overall rigidity of the frame 1 and prevent deformation or breakage due to heavy loads or impacts. Support rods 2 and fixed rods 3 are installed on the upper part of the frame 1. Both the fixed rods 3 and the support rods 2 are welded to the frame 1. Multiple fixed rods 3 are provided, each with a support frame. The support frames include support frame one 4 and support frame two 5, with two support frames two 5 and two support frames one 4, forming a symmetrical support structure. A conveyor roller is rotatably connected between any two adjacent support frames via bearings. The upper part of the conveyor roller is in close contact with the conveyor belt 7, supporting the conveyor belt 7 and guiding its smooth operation. Both ends of the conveyor belt 7 are connected to drive rollers 6, which are rotatably connected to both ends of the frame 1 via bearings. The drive rollers 6 are connected to an external drive motor, and their rotation drives the conveyor belt 7 to circulate, achieving continuous material conveying.

[0020] The frame 1 and support frame 4 are detachably connected by bolts, which is firm and easy to disassemble and maintain. The installation position of support frame 4 can be adjusted according to working conditions. Support frame 4 and support frame 5 are rotatably connected by bearings. There are two conveyor rollers 8. Both conveyor rollers 8 are arranged in an inclined state. Support frame 25 is welded and fixed to the fixing rod 3. Support frame 25 is rotatably connected by bearings. The two conveyor rollers 8 are symmetrically arranged about conveyor roller 9. Through the symmetrical inclined structure, the conveyor belt 7 is guided to keep running in the center and avoids the conveyor belt 7 from running off-center.

[0021] The buffer mechanism includes a buffer roller 10 and a buffer pad 11. The buffer pad 11 is made of a composite material of nitrile rubber and polyurethane and is laid on the upper surface of the conveyor belt 7, directly contacting the material. It can directly absorb part of the impact force when the material falls, avoiding material damage or wear of the conveyor belt 7 caused by direct rigid contact between the material and the conveyor belt 7. The buffer roller 10 is set at the lower part of the conveyor belt 7 and is located at the end of the fixed rod 3. The buffer roller 10 is connected to the frame 1 through a connecting plate 12. A spring assembly 13 is set at the lower part of the connecting plate 12. The spring assembly 13 adopts a disc spring stacking design. A guide post 14 is set between the spring assembly 13 and the connecting plate 12. The guide post 14 is welded and fixed to the connecting plate 12. The side end of the guide post 14 is slidably connected to the frame 1 to limit the displacement direction of the connecting plate 12, ensuring that the connecting plate 12 drives the buffer roller 10 to move up and down smoothly and avoid deviation.

[0022] The lower part of the guide column 14 is connected to the first spring assembly 13 via the fixing plate 15. The lower part of the first spring assembly 13 is hinged to the fixing bracket 16. The end of the fixing bracket 16 is welded to the support leg 29 of the frame 1. A connecting rod 18 is also welded to the end of the fixing bracket 16. The fixing bracket 16 also has a second spring assembly 17, which is a cylindrical helical spring that works in conjunction with the first spring assembly 13. The upper part of the second spring assembly 17 is welded to the connecting plate 12 for auxiliary buffering and further improves the buffering effect. The end of the connecting plate 12 is hinged to the lower end of the frame 1. The upper part of the connecting plate 12 is welded to the guide column 14. The guide column 14 and the frame 1 are hinged via the connecting column 28 to ensure that the guide column 14 can move flexibly.

[0023] Two buffer springs 19 are installed between two adjacent support frames 1-4. The bottom of each buffer spring 19 is welded with a lower lifting ring 20. The two lower lifting rings 20 are fixed together by welding a straight rod 21. The ends of the two lower lifting rings 20 are respectively connected to the mounting base 22. The mounting base 22 is fixedly connected to the frame 1 by bolts. The upper part of each buffer spring 19 is welded with an upper lifting ring 23. The two upper lifting rings 23 are connected together by a thin straight rod 24. The upper part of the upper lifting ring 23 is rotatably connected to a top roller 25 through a bearing. The top roller 25 is in direct contact with the conveyor belt 7, supporting the conveyor belt 7 and bearing the impact force when the material falls. At the same time, it guides the conveyor belt 7 to run smoothly and evenly transmits the impact force to the buffer structure below, avoiding local stress concentration on the conveyor belt. The other end of the top roller 25 is rotatably connected to the connection hole of another upper lifting ring 23 through a bearing. The top roller 25 is in close contact with the lower surface of the conveyor belt 7 to achieve auxiliary buffering and support, and further disperse the impact force.

[0024] The conveyor belt 7 is tactilely connected to the limiting rollers 26. The limiting rollers 26 are located at the lower part of the frame 1. There are multiple limiting rollers 26, which are evenly arranged along the length of the frame 1. Each limiting roller 26 is detachably connected to the frame 1 by bolts. This is used to limit the vertical displacement of the conveyor belt 7, further improve the running stability of the conveyor belt 7, and prevent the conveyor belt 7 from jumping excessively due to impact.

[0025] The specific working process is as follows: The external drive motor is started, driving the transmission roller 6 to rotate. The transmission roller 6 drives the conveyor belt 7 to circulate. The material is conveyed to the feed end of the conveyor belt 7. The material moves with the conveyor belt 7. When the material falls from a height and impacts the conveyor belt 7, it first absorbs part of the impact force through the buffer pad 11, reducing the rigid contact between the material and the conveyor belt 7. Subsequently, the impact force is transmitted to the buffer roller 10 at the bottom and the top roller 25 at the top of the conveyor belt 7. The buffer roller 10 compresses the spring assembly 13 and the spring assembly 27 through the connecting plate 12. The spring assembly 13 and the spring assembly 27 undergo elastic deformation, absorbing the impact force step by step. The guide post 14 restricts the displacement direction of the connecting plate 12. To ensure smooth buffering, the buffer springs 19 between adjacent support frames 4 further absorb residual impact force through the top roller 25, achieving multi-stage buffering. During material conveying, two symmetrically inclined conveyor rollers 8 guide the conveyor belt 7 to run in the center, and the limiting roller 26 restricts the vertical displacement of the conveyor belt 7 to prevent it from deviating or jumping excessively. The residual force after buffering is distributed and transmitted through the fixed bracket 16 and the frame 1 to ensure the overall stable operation of the device. When the impact force disappears, the spring group 13, the spring group 2 17 and the buffer spring 19 reset, driving the buffer roller 10 and the top roller 25 back to their initial positions, ensuring the continuous and smooth operation of the conveyor belt 7.

[0026] Therefore, this invention employs the aforementioned multi-segment buffer high-strength conveyor device. Through the multi-segment buffering combination of buffer pads, buffer rollers, spring group one, spring group two, and buffer springs, the impact force of falling materials can be gradually offset, preventing the impact force from directly acting on the conveyor belt and frame. This effectively reduces conveyor belt wear and tear, prevents frame deformation, and extends equipment lifespan. The frame is made of high-strength steel and is equipped with reinforcing ribs. The support frame adopts a symmetrical structure design with evenly distributed fixing rods. The overall structure is rigid and has a high load-bearing capacity, making it suitable for long-term high-intensity conveying conditions and less prone to damage. The two conveyor rollers are symmetrically inclined about the second conveyor roller, guiding the conveyor belt to run in the center. Combined with the limiting roller's limiting effect, this effectively prevents the conveyor belt from deviating. At the same time, the coordinated support of the top roller and the conveyor roller ensures smooth conveyor belt operation and prevents material spillage. The support frame one is detachably bolted to the frame, and the limiting roller is detachably connected to the frame. The connection structure of the buffer components is reasonably designed, facilitating individual disassembly and replacement without requiring the entire machine to be shut down, reducing maintenance workload and costs.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
