[0036] Embodiment one

[0037] As Figures 1-4 shown, the embodiment provides a buffer cylinder roller, characterized in that it comprises a cylinder body 110, a partition assembly 120 and wear-resistant rubber 130.

[0038] The partition assembly 120 is arranged on the outer side wall of the cylinder body 110, and forms a grid structure on the outer side of the cylinder body 110.

[0039] The wear-resistant rubber 130 is cast in the grid of the grid structure, which provides uniform support for the wear-resistant rubber 130 through the grid structure, enhances the structural strength of the cylinder 110 and disperses impact load, improves wear resistance and impact resistance, and prolongs the service life.

[0040] The present application achieves the synergistic optimization of structural reinforcement and buffering performance by arranging the grid-shaped partition assembly 120 on the outer side wall of the roller and casting the wear-resistant rubber 130 in the grid. The grid structure provides a uniform support framework for the rubber, preventing excessive deformation or peeling of the rubber, and effectively disperses impact load through the porous layout. The casting process tightly combines the rubber and the cylinder 110 to form a high-elasticity buffer layer, significantly improving wear resistance and impact resistance, while facilitating maintenance and replacement. It is particularly suitable for heavy-load and high-frequency industrial transmission scenarios, which can significantly prolong the service life of the equipment and reduce maintenance costs.

[0041] Optionally, the partition assembly 120 includes a plurality of partition rings 121 and a plurality of partition plates 122. The partition rings 121 are coaxially sleeved on the outer side of the roller. The plurality of partition rings 121 partition the outer space of the cylinder 110 into a plurality of annular spaces. The partition plates 122 are arranged in the annular spaces, so that each annular space forms a grid structure arranged in a ring shape, thereby refining the support unit and enhancing the restraining force of the wear-resistant rubber 130 to prevent local stress concentration.

[0042] Illustratively, the partition plates 122 are arranged along the axial direction of the cylinder 110. By arranging the partition plates 122 in the axial direction, the material is uniformly distributed along the roller, reducing the risk of uneven load and optimizing the mechanical transmission path.

[0043] Optionally, the positions of the partition plates 122 on different annular spaces are correspondingly arranged to form a continuous support network, ensuring uniform stress distribution during roller rotation and avoiding vibration or wear.

[0044] In some embodiments, the partition rings 121 have first fluidization holes 123 corresponding to each grid, and the partition plates 122 have second fluidization holes 124. The wear-resistant rubber 130 is integrally cast on the surface of the cylinder 110. Through the first fluidization holes 123 and the second fluidization holes 124, the rubber filling density is improved, and the wear-resistant rubber 130 is tightly combined with the cylinder 110 and the partition assembly 120.

[0045] Illustratively, the cylinder 110 includes a support framework 111, a cylinder wall 112, and a main shaft 113. The cylinder wall 112 is connected to the outer side of the support framework 111 and forms a cylindrical structure. The main shaft 113 is installed on the axis of the cylindrical structure. The split design simplifies processing and assembly, the support framework 111 and the cylinder wall 112 cooperate to bear the load, and the main shaft 113 ensures smooth operation.

[0046] Optionally, the cylinder 110, the partition ring 121 and the partition plate 122 are made of wear-resistant high alloy steel material, which reduces wear under extreme working conditions through high hardness and impact resistance.

[0047] Embodiment Two

[0048] Based on the above technical solution, the embodiment discloses a material buffering device 200, which comprises a shell 210, a bearing seat 220, a driving mechanism 230 and a buffering drum roller 100 as described in the previous embodiment.

[0049] The inside of the shell 210 is provided with a feeding cylinder 211, the upper end and the lower end of the feeding cylinder 211 are open, and the lower end of the shell 210 is formed with a discharging port 212.

[0050] The buffering drum roller 100 is located below the lower end opening of the feeding cylinder 211; the two ends of the buffering drum roller 100 are connected with the two sides of the shell 210 through the bearing seat 220 respectively.

[0051] The driving mechanism 230 is used to drive the buffering drum roller 100 to rotate, and through directional flow guiding and rotational buffering, the material impact force is reduced, the discharging port 212 is orderly discharged, and the device is suitable for efficient conveying of large block materials.

[0052] The material buffering device adopts the directional design of the feeding cylinder 211 and the discharging port 212 to realize accurate feeding and orderly discharging of materials. The buffering drum roller 100 is stably supported by the bearing seat 220 and driven by the driving mechanism 230, and in combination with the grid structure and the wear-resistant rubber 130 characteristics, the centrifugal force generated by rotation disperses the material impact when the material falls, and the elastic deformation of the rubber layer absorbs kinetic energy, which significantly reduces the impact load of the material on the equipment. The overall structure is compact and has high protection, and is especially suitable for buffering and conveying of large block and high hardness materials in mining, metallurgy and other heavy industrial scenes, and has the characteristics of wear resistance, impact resistance and long service life, which effectively reduces the equipment failure rate and reduces the maintenance cost.

[0053] Exemplarily, the driving mechanism 230 comprises a speed reducer 231 and a shaft coupling 232, the speed reducer 231 is installed on a motor seat fixed on one side of the shell 210, the shaft coupling 232 drives and connects the speed reducer 231 and the buffering drum roller 100, and stable power output and torque transmission are used to ensure stable operation of the drum roller 100.

[0054] Specifically, in this embodiment, the coupling 232 includes a left half coupling 2321, a right half coupling 2322, and an intermediate slider 2323. The main shaft of the buffer roller is assembled with the left half coupling 2321, and the drive shaft of the reduction motor 231 is assembled with the right half coupling 2322, ensuring that the center of the drive shaft of the reduction motor 231 is concentric with the main shaft of the buffer roller. Finally, the left half coupling 2321 and the right half coupling 2322 are connected by the intermediate slider 2323.

[0055] Optionally, a coupling protective cover 233 is provided on the outside of the coupling 232. The coupling protective cover 233 is installed on the outside of the coupling 232 to reduce the risk of wear by isolating dust and foreign objects and improving equipment safety.

[0056] During equipment operation, material is concentrated through the feed cylinder 211 and impacts the low-speed rotating buffer roller. After the material decelerates, it flows out from the discharge port below the buffer roller. This design effectively enhances the impact and wear resistance of the buffer roller, avoids frequent equipment maintenance, and ensures stable equipment operation.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
