[0002] Spring plates with buffering function are respectively provided at both ends of the roller group of the belt conveyor used for conveying raw coal. It was found during operation that under the impact of large pieces of gangue, the spring plates lost their buffering effect, causing the middle roller of the roller group to cling to the roller frame beam and unable to rotate, thereby increasing the friction between the belt and the roller, reducing the service life of the belt and the roller, and sometimes causing the roller frame beam to deform. According to the Chinese utility model patent (application number: 202321303184.X), a belt conveyor roller shock-absorbing and buffering device is disclosed, including a roller frame, a triple shock-absorbing roller, and a mounting plate installed at both ends of the roller frame along the roller frame, wherein the triple shock-absorbing roller includes a middle shock-absorbing roller located in the middle and end shock-absorbing rollers located at both ends, and the two ends of the middle shock-absorbing roller are respectively hinged to one end of the end shock-absorbing roller, and the other end of the end shock-absorbing roller is respectively connected to the corresponding mounting plate; the bottom end of the mounting plate is movably connected to the roller frame by a hinge; a shock-absorbing spring is arranged between the mounting plate and the roller frame, and one end of the shock-absorbing spring is hinged to the mounting plate, and the other end is hinged to the roller frame. The mounting plate can rotate relative to the rotating shaft of the roller frame, and the shock-absorbing spring plays a role in supporting the mounting plate. Under the dual support of the movable installation of the mounting plate and the elasticity of the shock-absorbing spring, it plays a good buffering and shock-absorbing role.

[0003] However, the device still has the following problems: the device can only perform local buffering and shock absorption, and the overall buffering and shock absorption performance is not excellent enough. The triple shock-absorbing rollers of the device are suspended and easily deviate to the left and right during buffering and shock absorption, causing the conveyed materials to scatter. The triple shock-absorbing rollers of the device cannot be adjusted, have a single purpose, and are not flexible enough.

[0004] The utility model proposes a new solution to the above problems. Utility Model Content

[0026] like Figure 1-Figure 6 As shown, the belt conveyor buffer device provided in this embodiment includes a roller frame 1, and a triple shock-absorbing roller 2 located above the roller frame 1, the top of the roller frame 1 is connected to an adjusting plate 3 located on both sides of the triple shock-absorbing roller 2 through a first bolt 12, and an adjusting rod 4 hinged to the triple shock-absorbing roller 2 is slidably installed on the adjusting plate 3, both ends of the roller frame 1 are fixedly connected with a connecting plate 5, a mounting seat 6 is provided at the bottom of the connecting plate 5, a first shock absorber 7 is installed between the connecting plate 5 and the mounting seat 6, the triple shock-absorbing roller 2 includes a middle shock-absorbing roller 8 and end shock-absorbing rollers 9 located at both ends of the middle shock-absorbing roller 8, the top of the roller frame 1 is fixedly connected with a second shock absorber 10 located at both ends of the middle shock-absorbing roller 8, the top of the second shock absorber 10 is fixedly connected with a first articulated seat 11, and the middle shock-absorbing roller 8 and the end shock-absorbing roller 9 are mutually connected through the first articulated seat 11.

[0027] By setting the adjusting plate 3 and the first bolt 12, the angle between the end shock-absorbing roller 9 and the middle shock-absorbing roller 8 can be adjusted by adjusting the height of the adjusting plate 3, so that it is suitable for different scenes and has a wider range of uses; by setting the second shock absorber 10, the goods falling on the conveyor belt can be buffered and shock-absorbed to prevent damage to the conveyor belt, and by setting the adjusting rod 4, when the second shock absorber 10 acts, the adjusting rod 4 can slide to prevent damage to the end shock-absorbing roller 9; by setting the first shock absorber 7, the device can be buffered and shock-absorbed as a whole to prevent the falling goods from being too heavy to damage the roller frame 1.

[0028] In this embodiment, if Figure 2 , Figure 3 and Figure 6 As shown, one end of the adjusting rod 4 is fixedly connected to a second hinge seat 401 hinged to the end damping roller 9, and the other end of the adjusting rod 4 is fixedly connected to an end plate 402. The outer side of the adjusting rod 4 is sleeved with a spring 403 located between the end plate 402 and the adjusting plate 3, and the adjusting plate 3 is provided with a sliding hole 301 that is slidably matched with the adjusting rod 4. The arrangement of the spring 403 can ensure that the end damping roller 9 is always in a tensioned state, thereby ensuring the operating efficiency of the end damping roller 9.

[0029] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the top of the roller frame 1 is fixedly connected with an adjusting tube 101 that slidably cooperates with the adjusting plate 3, the adjusting tube 101 is provided with a connecting hole 102 that cooperates with the first bolt 12, and the adjusting plate 3 is provided with a matching hole 302 that cooperates with the first bolt 12.

[0033] Step 1: The goods fall onto the conveyor belt and impact the device. At this time, the first shock absorber 7 plays a buffering role on the roller frame 1 and the triple shock-absorbing roller 2 as a whole;

[0034] Step 2: The impact force acts on the end damping roller 9 and the middle damping roller 8 at the same time, and the second damper 10 has a buffering effect on the triple damping roller 2. The arrangement of the two second dampers 10 prevents the triple damping roller 2 from being greatly deflected;

[0035] Step 3: When different goods need to be transported, remove the first bolt 12, adjust the height of the adjustment plate 3, and then install the first bolt 12.

[0036] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
