Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to a shearing and recycling device. Background Technology

[0002] In the bar rolling process, the rolling line needs to shear the ends of the bars, and the resulting scrap steel ends need to be efficiently recycled and sorted. Current technologies generally employ a simple combination of a scrap steel receiving hopper and a steel chute (as shown in the attached diagram). Figure 6 As shown in the figure, the scrap head slides down into the receiving trolley or bin below by its own weight to achieve the initial sorting and collection of different types of scrap steel. This method is the basic configuration of the scrap steel recycling process in steel enterprises.

[0003] However, such traditional devices have significant drawbacks: due to the large height difference between the rolling mill platform and the receiving point, the hot and heavy sheared material head accumulates enormous impact potential energy during its descent. This powerful kinetic energy directly impacts the receiving hopper, steel chute, and final receiving container, causing the equipment structure to easily deform and crack. This not only generates significant noise and dust but also requires frequent shutdowns for maintenance, severely impacting production efficiency and resulting in high equipment maintenance costs. The core problem lies in the lack of an effective mechanism for dissipating the impact energy of the material head.

[0004] Therefore, in view of the shortcomings of the existing technologies, there is an urgent need to set up a multi-level, efficient buffer system in the scrap steel recycling path. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a shearing and recycling device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides a shearing and recycling device, comprising: Scrap steel receiving hopper; The steel chute has its inlet end connected to the scrap steel receiving hopper to guide the sheared head to slide towards the receiving container along a preset path; A primary buffer structure includes at least one buffer plate rotatably disposed within the scrap steel receiving hopper, and an elastic reset component connected between the buffer plate and the inner wall of the scrap steel receiving hopper; the elastic reset component is used to provide a torque to the buffer plate to make it tend to block the falling path of the scrap head; when the shearing scrap head falls into and impacts the buffer plate, it can drive the buffer plate to rotate to open the passage and allow the scrap head to enter the steel chute. A secondary buffer structure is provided in the trough of the steel chute to extend the sliding path of the shearing head; A three-stage buffer structure is provided in the outlet area of ​​the steel chute, including at least one suspension buffer chain curtain.

[0007] As a preferred embodiment of this utility model, the receiving container is a receiving trolley, which is located below the outlet of the steel chute.

[0008] As a preferred embodiment of this utility model, the buffer plate is provided with end shafts on both sides, and the end shafts are rotatably engaged with the rotating grooves opened on the inner side wall of the scrap steel receiving hopper.

[0009] As a preferred embodiment of this utility model, the elastic reset assembly includes a spring buffer, and a first hinge seat and a second hinge seat respectively disposed at both ends of the spring buffer. The first hinge seat is fixedly connected to the bottom end of the buffer plate, and the second hinge seat is fixedly connected to the inner wall of the scrap steel receiving hopper.

[0010] As a preferred technical solution of this utility model, the number of buffer plates is two, the two buffer plates are symmetrically arranged about the center line of the scrap steel receiving hopper, and when neither of the two buffer plates is impacted, their opposite inner sides approach each other to form a V-shaped normally closed structure.

[0011] As a preferred technical solution of this utility model, the secondary buffer structure includes multiple guide plates fixed to the inner wall of the steel trough, and the multiple guide plates are arranged in an alternating manner to form a zigzag buffer channel in the steel trough.

[0012] As a preferred embodiment of this utility model, the three-level buffer structure includes: Install a crossbeam, which is fixedly mounted at the outlet of the steel chute; Multiple hanging shafts are arranged at intervals along the length of the mounting beam; Multiple chains, each chain having its upper end attached to a hanging axle; A locking element is used to restrain the upper end of the chain on the hanger.

[0013] As a preferred embodiment of this utility model, the three-stage buffer structure further includes a counterweight block, the upper end of which has a hook adapted to the lowest end of the chain.

[0014] As a preferred technical solution of this utility model, the upper end of the buffer plate is provided with an installation groove, a wear-resistant plate is provided in the installation groove, and the bottom of the scrap steel receiving hopper and the steel chute are provided with a support for support.

[0015] The beneficial effects of this utility model are as follows: This utility model achieves efficient dissipation of the impact energy of high-temperature material heads by constructing a progressive three-stage buffer system. The system first completes the initial buffering and guidance through the buffer plate with elastic reset components in the scrap steel receiving hopper. Then, it utilizes the extended path structure set in the steel chute to achieve secondary deceleration through the continuous friction and collision of the material heads. Finally, with the help of the buffer chain curtain at the outlet, the energy is finally dispersed through the large swing and mutual collision of the chain. While ensuring smooth material collection, it significantly improves the durability and operational stability of the equipment. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0020] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0021] like Figure 1 and Figure 2 As shown, a shearing and recycling device includes: a scrap steel receiving hopper 1; a steel chute 2, the inlet end of which is connected to the scrap steel receiving hopper 1 to guide the sheared head to slide along a preset path toward the receiving container; a primary buffer structure, which includes at least one buffer plate 5 rotatably disposed within the scrap steel receiving hopper 1, and an elastic reset component connected between the buffer plate 5 and the inner wall of the scrap steel receiving hopper 1; the elastic reset component is used to provide a torque to the buffer plate 5 to make it tend to block the falling path of the head; when the sheared head falls into and impacts the buffer plate 5, it can drive the buffer plate 5 to rotate to open the passage and allow the head to enter the steel chute 2; a secondary buffer structure, which is disposed in the trough of the steel chute 2 to extend the sliding path of the sheared head; and a tertiary buffer structure, which is disposed in the outlet area of ​​the steel chute 2, including at least one suspended buffer chain curtain. The above technical solution solves the problems of high impact force of falling scrap, easy damage to receiving devices, and severe noise in existing technologies. Specifically, its working principle is to dissipate the huge kinetic energy of the scrap head through a progressive three-stage structure. In use, the high-temperature sheared scrap head first falls into the scrap steel receiving hopper 1, impacts the buffer plate 5 of the first-stage buffer structure, and rotates open after overcoming the torque of the elastic reset component, completing the initial energy buffering and guidance. The scrap head then enters the steel chute 2, where the second-stage buffer structure uses a long and complex path to achieve secondary deceleration through continuous friction between the scrap head and the chute wall. Finally, the scrap head impacts the buffer chain curtain of the third-stage buffer structure at the outlet. The chain curtain efficiently absorbs and disperses the remaining impact energy through large swings and mutual collisions, allowing the scrap head to fall into the receiving container at a safe speed. This significantly reduces equipment maintenance costs, extends equipment lifespan, and improves system operational stability and safety.

[0022] like Figure 1As shown, in this embodiment, the receiving container is a receiving trolley 4, which has multiple trolleys. The ground is laid on the guide rail to guide the receiving trolley 4 to slide. The receiving trolley 4 is driven by a motor and is located below the outlet of the steel chute 2. The above technical solution solves the problems of fixed hoppers requiring shutdown for cleaning and low recycling efficiency. Specifically, its working principle utilizes the mobility of the trolley to achieve continuous and efficient scrap steel collection and transfer. During operation, when the scrap steel in the receiving trolley 4 reaches a certain amount, the fully loaded trolley can be moved away and replaced with an empty trolley. The production process does not need to be interrupted, enabling rapid switching and transfer of different types of scrap steel and significantly improving the continuity and overall efficiency of production and recycling operations.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, the buffer plate 5 is provided with end shafts 6 on both sides, and the end shafts 6 are rotatably engaged with the rotating groove 7 opened on the inner side wall of the scrap steel receiving hopper 1. The above technical solution can solve the problem of the buffer plate 5 being inflexible or stuck during rotation. Specifically, its working principle is to provide a stable, low-friction rotation fulcrum, ensuring that the buffer plate 5 can open smoothly when subjected to impact, and accurately reset itself after the impact by relying on the elastic reset component. During operation, the gravity of the material head acts on the surface of the buffer plate 5 and is converted into a torque that causes the buffer plate 5 to rotate around the end shaft 6, ensuring that the primary buffer structure responds promptly, operates reliably, and has low mechanical wear and a long service life.

[0024] like Figure 2 and Figure 5 As shown, in this embodiment, the elastic reset assembly includes a spring buffer 10, and a first hinge seat 11 and a second hinge seat 12 respectively disposed at both ends of the spring buffer 10. The first hinge seat 11 is fixedly connected to the bottom end of the buffer plate 5, and the second hinge seat 12 is fixedly connected to the inner wall of the scrap steel receiving hopper 1. The above technical solution solves the problem of needing a reliable driving method that provides both reset force and good buffering performance. Specifically, its working principle is that the spring buffer 10, as the core damping element, is stretched or compressed when the buffer plate 5 is pushed open, absorbing a large amount of impact energy; when the impact force disappears, its elastic potential energy drives the buffer plate 5 to reset to the normally closed state. During operation, the first hinge seat 11 and the second hinge seat 12 provide stable force transmission nodes, achieving efficient absorption of impact energy, effectively suppressing reset impact and noise, and enabling the buffer plate 5 to automatically reset and standby.

[0025] like Figure 2 As shown, in this embodiment, there are two buffer plates 5. The two buffer plates 5 are symmetrically arranged about the center line of the scrap steel receiving hopper 1. When neither of the two buffer plates 5 is impacted, their opposite inner sides approach each other to form a V-shaped normally closed structure. The above technical solution solves the problems of the cumbersome opening and closing of a single large buffer plate 5 and its poor buffering and guiding effect on non-centered falling material heads. Specifically, its working principle is to use a V-shaped structure to guide the falling material head, so that its impact force is more concentrated to drive the buffer plate 5 to rotate. At the same time, the two buffer plates 5 on both sides can move independently to adapt to material heads of different sizes and landing points. During operation, the material head impacts at the V-shaped sharp corner, naturally diverting to both sides and pushing the buffer plates 5 apart, improving the capture rate and buffering efficiency of the material head, and allowing the material head to enter the steel chute 2 more smoothly.

[0026] like Figure 2 As shown, in this embodiment, the secondary buffer structure includes multiple guide plates 13 fixed to the inner wall of the steel trough 2. The multiple guide plates 13 are arranged in an alternating manner and form a zigzag buffer channel in the steel trough 2. The above-mentioned technical solution solves the technical challenge of effectively extending the material head's sliding path and achieving sufficient deceleration within a limited space. Specifically, its working principle is to forcibly change the material head's trajectory, causing it to collide, rub, and tumble multiple times with the guide plate 13, transforming linear acceleration into zigzag deceleration. During operation, the material head collides left and right within the zigzag channel, continuously consuming its kinetic energy. This significantly reduces the material head's exit velocity at the end of the steel chute 2, creating favorable conditions for the third-stage buffer.

[0027] like Figure 3 As shown, in this embodiment, the three-stage buffer structure includes: a mounting beam 14, which is fixedly mounted at the outlet of the steel trough 2; multiple hanging shafts 15, which are spaced apart along the length of the mounting beam 14, and the hanging shafts 15 have radially penetrating through holes on their outer circumference; multiple chains 18, the upper end of each chain 18 being sleeved on a hanging shaft 15; and a locking member, which is used to restrict the upper end of the chain 18 to the hanging shaft 15, the locking member including a positioning bolt 16 and a positioning nut 17 adapted thereto, the positioning bolt 16 being able to be inserted into the through hole; The above-mentioned technical solution can solve the problem of how to achieve reliable and efficient final buffering at the high-impact, high-wear outlet position. Specifically, its working principle is to use a group of suspended chains 18 to form a flexible barrier. When the material head impacts, the chains 18 convert the impact kinetic energy of the material head into their own kinetic and potential energy through their own displacement, swinging, and mutual collisions, and distribute it to multiple chains 18. The operation steps include hanging the upper end of the chains 18 on the hanging shaft 15 and fixing it with locking devices. The buffering effect is significant, impact-resistant, high-temperature resistant, easy to maintain, and can effectively prevent material head splashing.

[0028] like Figure 4 As shown, in this embodiment, the three-stage buffer structure also includes a counterweight 19, the upper end of which has a hook 20 adapted to the lowest end of the chain 18. The above technical solution solves the problem of lightweight chain 18 being easily knocked apart and having insufficient cushioning force when buffering large material heads. Specifically, its working principle is to increase the mass of the lower part of chain 18 to improve its inertia and stability, so that the material head needs to consume more energy to push chain 18, while suppressing excessive swinging of chain 18. During operation, counterweight 19 is connected to the lowest end of chain 18 through its hook 20. This enhances the overall damping effect and impact resistance of chain 18, resulting in a lower final material drop speed.

[0029] like Figure 5 As shown, in this embodiment, the upper end of the buffer plate 5 is provided with an installation groove 9, and a wear-resistant plate 8 is provided in the installation groove 9. The bottom of the scrap steel receiving hopper 1 and the steel chute 2 are provided with a support bracket 3 for support. The above technical solution solves the problems of high maintenance costs after the buffer plate 5 is directly worn and insufficient stability of the entire device due to impact and vibration. Specifically, its working principle is as follows: the wear-resistant plate 8, as a vulnerable part that directly bears the impact and wear of the high-temperature material head, is installed in the mounting groove 9 of the buffer plate 5 in a detachable manner, realizing the specialization and modularization of the working surface; the bracket 3 provides a stable bottom support for the entire recycling device, ensuring that it does not shake or sink during operation. During operation, when the wear-resistant plate 8 is worn to the point of needing replacement due to long-term use, it can be easily removed from the mounting groove 9 and replaced with a new one without replacing the entire buffer plate 5; the bracket 3 is fixed to the foundation by anchor bolts and other components.
