Technical Field

[0001] This utility model relates to the field of conveyor belt shock absorption and buffering technology, specifically a composite buffer bed. Background Technology

[0002] The buffer bed is mainly used to replace the buffer roller. The buffer bed is composed of buffer strips, which mainly use a high-elasticity special rubber layer to fully and effectively absorb the impact force when the material falls, greatly reducing the impact of the material falling on the conveyor belt, and truly improving the stress condition at the drop point. The use of the buffer bed ensures the surface-to-surface contact of the conveyor belt, and the force is evenly distributed. It effectively prevents the longitudinal tearing of the belt caused by the breakage or detachment of the roller, and at the same time greatly reduces the probability of the belt being longitudinally torn after being penetrated by sharp objects or sharp materials.

Shock-absorbing feet are installed at the corners of the lower end of the base plate, and the base plate and the shock-absorbing feet are connected by bolts. A platform is installed on both sides of the lower end of the buffer bed steel plate. Several first buffer springs are installed between the platform and the base plate, and the first buffer springs are connected to the platform and the base plate by screws. The buffer bed steel plate is also connected to the platform by screws.

[0004] However, the existing buffer bed uses spring buffering, which results in poor buffering stability and low buffering efficiency. Utility Model Content

[0011] Preferably, the two ends of the shock-absorbing beam stiffener plate at the upper end of the shock-absorbing beam support leg are inclined upwards and the extension line of the structure is perpendicular to the first support leg.

[0012] Beneficial effects

[0013] This invention provides a composite buffer bed that solves the technical problem of poor buffering stability and low buffering efficiency caused by the use of springs in existing buffer beds. The buffer bed of this invention consists of ultra-high molecular weight polyethylene (UHMWPE) shock absorbers, which utilize a high-elasticity special rubber layer to effectively absorb the impact force of falling materials, greatly reducing the impact on the conveyor belt and truly improving the stress condition at the material drop point. The surface contact between the buffer strip and the conveyor belt effectively prevents damage to the conveyor belt, ensuring uniform stress on the conveyor belt at the drop point, significantly reducing daily repair and maintenance costs. It effectively eliminates material splashing and leakage caused by uneven stress on the conveyor belt. The smooth surface of the UHMWPE minimizes friction during conveyor belt operation, and the arc-shaped design of the polyethylene layer ensures smooth and fluid conveyor belt operation. The ultra-elasticity special rubber layer can absorb the impact force of materials to the maximum extent. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a composite buffer bed, including several support beams 1, a pair of side support legs 2 fixedly installed on the support beams 1, a first support leg 3 fixedly installed at the top of the side support legs 2, a pair of shock-absorbing components provided on the support beams 1 and between the pair of side support legs 2, the shock-absorbing components including a lower fixed plate 4 and an upper fixed plate 5, the lower fixed plate 4 fixedly installed on the support beams 1, shock-absorbing beam legs 6 fixedly installed on the upper wall of the upper fixed plate 5, shock-absorbing beam stiffeners 7 fixedly installed between the upper ends of the shock-absorbing beam legs 6, an elastic component movably installed between the lower fixed plate 4 and the upper fixed plate 5, buffer strip bottom plates 8 fixedly installed between the upper ends of the first support legs 3 and between the shock-absorbing beam stiffeners 7, and ultra-high molecular weight polyethylene shock-absorbing blocks 9 fixedly installed on the buffer strip bottom plates 8.

[0021] In this embodiment, a pair of connecting plates 10 are fixedly installed on the opposite wall surfaces of the lower fixing plate 4 and the upper fixing plate 5, respectively. The elastic component includes an elastic rubber shell 11, in which a first elastic rubber 12 is inserted. The first elastic rubber 12 has a square hole, in which a square shaft 13 is inserted. Threaded grooves are respectively opened at both ends of the square shaft. A pair of mounting holes are opened on the connecting plate 10, in which bolts 14 are inserted. The bolts 14 are screwed into the threaded grooves.

[0022] In this embodiment, the connecting plate 10 on the lower fixing plate 4 and the connecting plate 10 on the upper fixing plate 5 are staggered, and the elastic rubber shell 11 is inclinedly installed between the connecting plate 10 on the lower fixing plate 4 and the connecting plate 10 on the upper fixing plate 5.

[0023] In this embodiment, the shock-absorbing beam stiffener 7 at the upper end of the shock-absorbing beam support leg 6 is inclined upward at both ends.

[0024] In this embodiment, the first support leg 3 is installed at an angle on the upper end of the side support leg 2.

[0025] In this embodiment, the shock-absorbing beam stiffener 7 at the upper end of the shock-absorbing beam support leg 6 is arranged such that the extended lines of the upwardly inclined structure are perpendicular to the first support leg 3.

[0026] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0027] Example: As shown in the accompanying drawings, during use, the device is placed below the conveyor belt. When the material falls onto the conveyor belt, it impacts the surface of the conveyor belt. The conveyor belt and the material first impact the ultra-high molecular weight polyethylene shock absorber 9 for stress relief and buffering. As the material continues to move downward, the buffer strip bottom plate 8 pushes the shock absorber crossbeam stiffener 7, which in turn pushes the shock absorber crossbeam support leg 6. The shock absorber crossbeam support leg 6 pushes the upper fixed plate 5. Since the elastic rubber shell 11 is installed at an incline between the connecting plate 10 on the lower fixed plate 4 and the connecting plate 10 on the upper fixed plate 5, the upper fixed plate 5 pushes the square shaft 13 as it moves downward. The square shaft 13 compresses the first elastic rubber 12, causing the first elastic rubber 12 to deform, thus providing stress relief and buffering. The ultra-high molecular weight polyethylene shock absorber 9 on the first support leg 3 provides a certain degree of protection, preventing the material from being removed from the conveyor belt.

[0028] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
