Description

Technical Field

[0001] This utility model relates to the field of chain plate feeder technology, and in particular to a chain plate feeder with a buffer component. Background Technology

[0002] As a common continuous conveying equipment, chain plate feeders play an indispensable role in many fields of industrial production. They are widely used in mining, metallurgy, coal, building materials, chemical and other industries. They are mainly used to convey block, granular or powdery materials and can adapt to the conveying needs of different materials to achieve stable and continuous material supply.

[0003] A chain plate feeder for a scrap steel crushing production line, with announcement number CN215901938U, specifically relates to the field of scrap steel crushing technology. It includes a feeder body and a buffer assembly. A first support leg is fixedly provided on the side of the feeder body away from the buffer assembly. A rotating block is rotatably provided on the side of the first support leg away from the feeder body. A support block is fixedly rotatably provided on the side of the rotating block away from the first support leg. A second support leg is fixedly provided on the side of the feeder body close to the buffer assembly. When adjusting the height of one side of the feeder body, the invention can be achieved by opening a cylinder to move a first sliding rod towards the first fixed block, ultimately causing the connecting plate to move upwards. This, combined with the rotating block, causes one side of the feeder body to move upwards. To prevent large pieces of scrap steel from impacting the crushing wheel and damaging it when the height is high, the invention can tilt the buffer plate by rotating it and then fix it with a screw.

[0004] During the material conveying process, especially when conveying large, hard materials (such as ore and lump coal), the material will impact the inner structure of the feeder at a certain speed and force, causing damage to the inner wall of the chain plate feeder and affecting its service life. The existing technology mentioned above lacks protection for the inner wall of the chain plate feeder, which increases equipment maintenance costs and economic costs. Therefore, corresponding improvements are needed. Summary of the Invention

[0005] The purpose of this utility model is to provide a chain plate feeder with a buffer component to solve the problem mentioned in the background art that the existing chain plate feeders lack inner wall protection and have a reduced service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chain plate feeder with a buffer assembly, comprising a chain plate feeder body, a drive roller, a driven roller, and a feeding chain plate. The chain plate feeder body is provided in two parts, and a drive roller and a driven roller are respectively connected to both ends of the chain plate feeder body. A feeding chain plate is provided between the drive roller and the driven roller.

[0007] One end of the drive roller passes through the main body of the chain feeder and is connected to a drive motor. The drive motor is fixed to the outside of the main body of the chain feeder via a support plate. A support platform is connected to the bottom of the main body of the chain feeder. A control panel is provided on the outside of the main body of the chain feeder. Support plates are connected to both sides of the top of the main body of the chain feeder, and buffer mechanisms are provided inside the support plates. A material guiding component is provided at one end of the feeding chain.

[0008] Furthermore, the buffer mechanism includes buffer springs disposed on both sides inside the support plate, and one end of each buffer spring is connected to a compression block. A buffer block is disposed between the compression blocks, and a connecting rod is fixed on one side of the buffer block. A damping spring is evenly wound on the connecting rod.

[0009] Furthermore, the cross-section of the extrusion block is trapezoidal, and the cross-section of the buffer block is an isosceles trapezoid.

[0010] Furthermore, each of the connecting rods is connected to a protective plate at one end, and an expansion plate is fixed to the top of each protective plate. An anti-collision block is connected to one side of each expansion plate, and the anti-collision block has an arc-shaped cross-section and is made of rubber.

[0011] Furthermore, the material guiding assembly includes a rotating shaft connected between the main body of the chain plate feeder, and a material guiding plate is sleeved on the outside of the rotating shaft, and a driving assembly is provided at one end of the rotating shaft.

[0012] Furthermore, the drive assembly includes a protective box fixed to the outside of the chain feeder body, and a power motor is located at the top of the protective box. The output shaft of the power motor extends into the interior of the protective box and is connected to a worm gear. A worm wheel meshes with one side of the worm gear, and a fixed rotating shaft passes through the interior of the worm wheel.

[0013] Furthermore, the guide plate is made of stainless steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the chain plate feeder with buffer component has a buffer protection effect, and the unloading is convenient and efficient;

[0015] Corresponding protective plates are installed on both sides of the main body of the chain plate feeder to effectively protect the inner structure of the chain plate feeder when conveying hard materials. In conjunction with rubber anti-collision blocks, the impact energy of the materials is absorbed, reducing the direct impact force of the materials on the side wall of the feeder, thereby protecting the side wall from damage and avoiding problems such as deformation and cracking of the side wall.

[0016] When material hits the anti-collision block, it pushes the protective plate to move outward and causes the connecting rod to move synchronously. During this process, the damping spring is compressed, which reduces the impact force. Furthermore, the buffer block moves synchronously to resist the squeezing blocks on both sides, causing them to move horizontally and squeezing the buffer spring to contract, further reducing the impact force and enhancing the protection effect on the main body of the chain plate feeder.

[0017] The worm gear is driven by a motor to rotate, and the worm gear meshes with the worm wheel, which in turn rotates the protective box, causing the guide plate to flip. This allows the guide plate angle to be adjusted to adapt to the flow characteristics of different materials. For highly free-flowing powdery materials, reducing the guide plate angle can slow down the flow rate and prevent material splashing. For poorly free-flowing lumpy materials, increasing the angle can ensure that the material slides down smoothly and improve unloading efficiency.

[0018] The guide plate is made of stainless steel, which is highly corrosion-resistant, ensuring the service life of the guide plate and the purity of the materials. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-5 The present invention provides the following technical solution: Example 1:

[0028] To address the lack of internal wall protection in existing chain plate feeders, the following technical solution is proposed: a chain plate feeder with a buffer assembly, comprising a chain plate feeder body 1, a drive roller 2, a driven roller 16, and a feeding chain plate 3. The chain plate feeder body 1 consists of two parts, with the drive roller 2 and the driven roller 16 connected to its two ends respectively, and the feeding chain plate 3 positioned between the drive roller 2 and the driven roller 16.

[0029] One end of the drive roller 2 passes through the main body 1 of the chain plate feeder and is connected to the drive motor 4. The drive motor 4 is fixed to the outside of the main body 1 of the chain plate feeder through the support plate. The bottom end of the main body 1 of the chain plate feeder is connected to the support platform 14. The outside of the main body 1 of the chain plate feeder is equipped with a control panel 15.

[0030] The top two sides of the chain plate feeder body 1 are connected to support plates 5, and the support plates 5 are equipped with buffer mechanisms 6. The buffer mechanism 6 includes buffer springs 601 set on both sides inside the support plates 5, and one end of each buffer spring 601 is connected to a pressing block 602. A buffer block 603 is set between the pressing blocks 602, and a connecting rod 604 is fixed on one side of the buffer block 603. A damping spring 605 is evenly wound on the connecting rod 604.

[0031] Please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 4 In one embodiment, when the material falls onto the feeding chain plate 3, the drive motor 4 drives the active roller 2 to rotate, which makes the feeding chain plate 3 run and thus transport the material. During this process, if a large mass of material hits the protective plate 7, it will push the protective plate 7 to move to both sides, causing the connecting rod 604 to move synchronously and compress the damping spring 605 to contract, thus initially buffering the impact force and achieving a reduction effect.

[0032] The cross-section of the extrusion block 602 is trapezoidal, and the cross-section of the buffer block 603 is an isosceles trapezoid.

[0033] Please refer to the details. Figure 2 , Figure 5 In one embodiment, during the movement of the connecting rod 604, the buffer block 603 is pushed to move synchronously. The buffer block 603 moves into the support plate 5, so that the inclined side of the buffer block 603 abuts against the inclined surface of the extrusion block 602, pushing the extrusion block 602 to move to both sides and squeezing the buffer spring 601, so that the force is compressed, thereby further reducing the impact force generated, with a better force relief effect, achieving the purpose of protecting the inner wall of the chain plate feeder body 1;

[0034] One end of each connecting rod 604 is connected to a protective plate 7, and an outer expansion plate 702 is fixed to the top of each protective plate 7. An anti-collision block 701 is connected to one side of each outer expansion plate 702, and the anti-collision block 701 has an arc-shaped cross section and is made of rubber.

[0035] Please refer to the details. Figure 4 In this embodiment, the protective plate 7 is used in conjunction with the rubber anti-collision block 701 to protect the material from being damaged by the impact of high-hardness material on the inner wall of the chain feeder body 1 during the feeding process. The anti-collision block 701 is provided with a corresponding outward expansion plate 702, which can effectively prevent material from splashing out. Example 2:

[0036] This embodiment differs from Embodiment 1 in that the material guiding component can improve the unloading efficiency of different materials. Therefore, the following technical solution is disclosed: a material guiding component is provided at one end of the feeding chain plate 3. The material guiding component includes a rotating shaft 9 connected between the main body 1 of the chain plate feeder, and a material guiding plate 8 is sleeved on the outside of the rotating shaft 9. A drive component is provided at one end of the rotating shaft 9. The drive component includes a protective box 10 fixed to the outside of the main body 1 of the chain plate feeder, and a power motor 13 is provided at the top of the protective box 10. The output shaft end of the power motor 13 extends into the interior of the protective box 10 and is connected to a worm gear 12. A worm wheel 11 is meshed on one side of the worm gear 12, and the rotating shaft 9 is fixed through the interior of the worm wheel 11.

[0037] The guide plate 8 is made of stainless steel.

[0038] Please refer to the details. Figure 1 , Figure 3 In this embodiment, the material conveyed on the feed chain plate 3 falls from the guide plate 8 to achieve unloading. The power motor 13 drives the worm 12 to rotate, and the worm 12 meshes with the worm wheel 11, which in turn causes the rotating shaft 9 and the guide plate 8 to flip, so that the guide plate 8 is tilted at different angles to meet the unloading of materials with different characteristics. The guide plate 8 is made of stainless steel, which has good corrosion resistance, high strength, and longer service life.
