Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing buffer bed technology, and in particular to a low-resistance shock-absorbing buffer bed with adjustable groove angle. Background Technology

[0002] Traditional belt conveyors typically use independent buffer rollers or fixed buffer beds in the material drop zone. This design presents several application problems. Using buffer rollers alone results in poor cushioning capacity, failing to effectively absorb the impact of falling materials and making the rollers prone to damage. Using buffer beds alone increases friction between the belt and the bed, increasing power consumption and shortening the belt's lifespan. Furthermore, the angles of these configurations are fixed and cannot be adjusted, making it difficult to adjust the trough angle to meet the needs of different materials without replacing the equipment. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a low-resistance shock-absorbing buffer bed with adjustable groove angle, which can adjust the groove angle and has a good buffering effect, while also reducing the friction between the belt and the buffer bed.

[0004] The technical solution adopted by this utility model is: a low-resistance shock-absorbing buffer bed with adjustable groove angle, including a pair of parallel mounting frames, and multiple crossbeams are mounted on the mounting frames via a shock-absorbing mechanism. A first roller frame is fixed between the multiple crossbeams. The first roller frame is equipped with multiple first rubber buffer plates and first buffer rollers, and the first rubber buffer plates and first buffer rollers are alternately installed. The crossbeams are provided with adjustment frames on both sides of the first rubber buffer plates, and the free end of the adjustment frame is provided with an adjustment rod between the adjustment frame and the crossbeam for adjusting the tilt angle of the adjustment frame. A second roller frame is installed between the adjustment frames, and the second roller frame is equipped with second rubber buffer plates and second buffer rollers that correspond one-to-one with the first rubber buffer plates and first buffer rollers on the first roller frame.

[0005] Preferably, the shock absorption mechanism includes a shock absorption spring and mounting seats at both ends of the crossbeam. The mounting seats have through holes, and the mounting brackets have through holes. A guide rod passing through the through holes and the through holes and vertically downwards is mounted on the mounting seats. The end of the guide rod is provided with a threaded rod. After the guide rod passes through the through holes, a locking nut is installed on the threaded rod. The shock absorption spring is located between the mounting seats and the mounting brackets and is sleeved around the guide rod.

[0006] Preferably, the adjusting rod is a hydraulic rod, and the two ends of the hydraulic rod are respectively hinged to the adjusting frame and the crossbeam.

[0007] Preferably, both the first and second rubber buffer plates are made of highly elastic and highly wear-resistant polymer rubber materials, such as polyurethane rubber.

[0008] Preferably, the mounting bracket is made of channel steel.

[0009] The beneficial effects of this utility model are as follows: By adjusting the adjusting rods on both sides and changing the length of the pull rods, the adjusting frames on both sides can be rotated to achieve angle changes. The large-area first and second rubber buffer plates in this utility model absorb the impact of falling materials, protect the belt, and reduce the damage of materials to the belt conveyor. The first and second buffer rollers reduce the friction on the belt by rotating themselves, making the material transport smoother. The crossbeam is connected to the mounting frame through a shock-absorbing mechanism, which is based on a shock-absorbing spring. The shock-absorbing spring can convert the impact of falling materials into elastic potential energy through its own extension and contraction, further buffering the impact of materials and providing secondary protection for the belt from damage.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0014] like Figure 1-2As shown, this embodiment provides a low-resistance shock-absorbing buffer bed with adjustable groove angle, including a pair of parallel mounting frames 1. Multiple crossbeams 3 are mounted on the mounting frames 1 via a shock-absorbing mechanism 2. The crossbeams 3 are connected to the mounting frames 1 through the shock-absorbing mechanism 2. The shock-absorbing mechanism 2 is based on a shock-absorbing spring 12. The shock-absorbing spring 12 can convert the impact of the material falling into elastic potential energy through its own extension and contraction, thereby further buffering the impact of the material and protecting the tape from damage.

[0015] A first roller frame 4 is fixed between multiple crossbeams 3. The first roller frame 4 is equipped with multiple first rubber buffer plates 5 and first buffer rollers 6, which are alternately arranged. Adjusting frames 7 are provided on both sides of the crossbeams 3, and adjusting rods 8 are provided between the free ends of the adjusting frames 7 and the crossbeams 3 for adjusting the tilt angle of the adjusting frames 7. This invention achieves angle changes by adjusting the adjusting rods 8 on both sides, thereby changing the length of the pull rods and driving the adjusting frames 7 on both sides to rotate. A second roller frame 9 is installed between the adjusting frames 7. The second roller frame 9 is equipped with second rubber buffer plates 10 and second buffer rollers 11, corresponding one-to-one with the first rubber buffer plates 5 and first buffer rollers 6 on the first roller frame 4. The large-area first rubber buffer plate 5 and second rubber buffer plate 10 in this utility model absorb the impact of falling materials, protect the belt, and reduce the damage of materials to the belt conveyor; wherein the first buffer roller 6 and the second buffer roller 11 reduce the friction force on the belt through their own rotation, making the material transportation smoother.

[0016] The shock absorption mechanism 2 includes a shock absorption spring 12 and mounting seats 13 located at both ends of the crossbeam 3. The mounting seats 13 have through holes 18, and the mounting bracket 1 has through holes 14. A guide rod 15 passing through the through holes 18 and through holes 14 and pointing vertically downwards is installed on the mounting seats 13. The end of the guide rod 15 has a threaded rod 16. After the guide rod 15 passes through the through holes 14, a locking nut 17 is installed on the threaded rod 16. The shock absorption spring 12 is located between the mounting seats 13 and the mounting bracket 1 and is sleeved around the guide rod 15. This design of the shock absorption mechanism 2 facilitates the installation and disassembly of the mounting seats and the mounting bracket, making the structure simple and easy to assemble.

[0017] Both the first rubber buffer plate 5 and the second rubber buffer plate 10 are made of highly elastic and highly wear-resistant polymer rubber materials, among which polyurethane rubber can be used. Polyurethane rubber has high mechanical strength and a wide range of adjustable hardness. It can maintain good elasticity even at high hardness, has strong load-bearing capacity, and is tear-resistant, oil-resistant, and ozone-resistant.

[0018] Mounting bracket 1 is made of channel steel, which facilitates operation.

[0019] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0020] The working principle is as follows: by adjusting the adjusting rods 8 on both sides, the length of the pull rods is changed, which drives the adjusting frames 7 on both sides to rotate, thereby changing the angle. The large-area first rubber buffer plate 5 and second rubber buffer plate 10 in this utility model absorb the impact of falling materials, protect the belt, and reduce the damage of materials to the belt conveyor. The first buffer roller 6 and the second buffer roller 11 reduce the friction of the belt by rotating themselves, making the material transportation smoother. The crossbeam 3 is connected to the mounting frame 1 through the shock absorption mechanism 2. The shock absorption mechanism 2 is based on the shock absorption spring 12. The shock absorption spring 12 can convert the impact of falling materials into elastic potential energy through its own extension and contraction, further buffering the impact of materials and protecting the belt from damage.

[0021] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
