Description

Technical Field

[0001] This utility model relates to the field of belt maintenance, and in particular to a belt protection device to prevent belt damage from impact. Background Technology

[0002] In industrial production and various engineering applications, belt conveyors are widely used as key equipment for material handling. However, traditional belt conveyors are prone to damage from falling materials. In existing technologies, materials falling onto the belt are often in a disordered state. Due to the lack of effective flow guidance and control, material accumulation and high-speed impacts on the belt occur frequently, resulting in excessive local stress on the belt, accelerated wear, a sharp reduction in lifespan, increased maintenance costs, and more frequent downtime, seriously hindering production continuity and efficiency improvement. Regarding the uniformity of material conveying, the lack of a flexible adjustment mechanism based on material characteristics and production needs makes it difficult to ensure uniform stress on all parts of the belt. Uneven material distribution leads to frequent belt misalignment, which not only affects the stability and quality of conveying but also exacerbates equipment wear and increases energy consumption. Furthermore, the device is not adaptable to materials with different flow rates, velocities, and properties, and cannot accurately adapt to changes in working conditions. For example, when handling large flow rates of lumpy materials, the fixed flow guiding structure makes it difficult to disperse the impact force; when handling small flow rates of powdery materials, it is easy to cause material accumulation and blockage, which greatly limits the scope of application. Its versatility and adaptability are prominent shortcomings, making it difficult to meet the needs of modern industry for efficient, stable, and diverse material conveying, thus creating an urgent need for new types of belt conveyors that are anti-impact and highly adaptable to material characteristics.

[0003] Therefore, it is necessary to propose a belt anti-impact device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a belt anti-impact device to solve the problem of excessive local stress on the belt caused by material accumulation and frequent high-speed impacts, which leads to accelerated wear and a sharp reduction in belt life.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-impact belt device includes a fixed frame, a conveyor on one side of the fixed frame, the conveyor including two belt shafts, a belt wound between the belt shafts, a receiving bin fixedly installed on the top of the fixed frame, an opening at the bottom of the receiving bin, an anti-wear guide box fixedly connected to the bottom opening of the receiving bin, the anti-wear guide box being positioned above the belt, and the top and one side of the anti-wear guide box being open, with multi-stage sliding groove adjustment structures provided at both ends of the front and rear sides inside the anti-wear guide box, each multi-stage sliding groove adjustment structure having a guide plate slidably installed on it, and a guide plate 2 connected to the side of each of the two guide plates 1 that are close to each other, the two guide plates 2 being connected together by a guide transmission plate, the guide transmission plate being used to drive the guide plates 2, causing the two guide plates 2 to float up and down, the two guide plates 1 adjusting their positions in the multi-stage sliding groove adjustment structure to adjust the inclination of the overall structure of the guide plates 1, guide plates 2 and guide transmission plate.

[0007] Preferably, the multi-stage slide groove adjustment structure includes four slide grooves arranged in parallel with each other, and the multi-stage slide groove adjustment structure also includes two adjustment grooves that pass through the four slide grooves.

[0008] Preferably, a limiting member is installed inside the groove. The limiting member has a "C" shaped structure and a protrusion is provided on one side of the top of the limiting member.

[0009] Preferably, the first guide plate, the second guide plate, and the guide transmission plate are all connected by hinges.

[0010] Preferably, a transmission component is fixedly connected to the bottom of the flow guide plate, one end of the transmission component is movably connected to a transmission rod, and the other end of the transmission rod is movably connected to a turntable.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In this invention, for belt protection, the flexibly adjustable flow guiding system precisely controls the material falling onto the belt, effectively preventing belt damage caused by material accumulation or high-speed impact, significantly extending belt life, reducing equipment maintenance costs and downtime, and promoting production continuity and efficiency. In terms of material conveying, the inclination and floating amplitude of the guide plates can be flexibly adjusted according to material characteristics and production needs, achieving uniform material distribution on the belt, ensuring even stress distribution throughout the belt, preventing excessive local wear or belt misalignment due to uneven material distribution, improving belt stability and material conveying quality, and making it less likely for material to stick to the guide plates, thus accelerating conveying efficiency. In terms of device adaptability, the multi-stage chute adjustment structure combined with the vertically floating guide plate design gives the device the ability to cope with changes in material flow rate, velocity, and properties. For handling large-flow lumpy materials, the guide plate parameters can be increased; for handling small-flow powdery materials, the parameters can be decreased, greatly expanding the scope of application, enhancing the equipment's versatility and adaptability, and laying a solid foundation for reliable belt conveyor operation in various industrial production scenarios.

[0025] 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.

[0026] This utility model provides, for example Figures 1-7 The illustrated anti-impact belt device includes a fixed frame 1. A conveyor is mounted on one side of the fixed frame 1. The conveyor includes two belt shafts 2, and a belt 3 is wound between the belt shafts 2. A receiving bin 4 is fixedly mounted on the top of the fixed frame 1. The bottom of the receiving bin 4 has an opening, and an anti-wear guide box 5 is fixedly connected to the bottom opening of the receiving bin 4. The anti-wear guide box 5 is positioned above the belt 3, and its top and one side are open. Both ends of the front and rear sides of the anti-wear guide box 5 are... A multi-stage chute adjustment structure 6 is provided, on which guide plates 7 are slidably installed. Guide plates 8 are connected to the sides of the two guide plates 7 that are close to each other. A guide transmission plate 9 is connected between the two guide plates 8. The guide transmission plate 9 is used to drive the guide plates 8 so that the two guide plates 8 float up and down. The tilt of the overall structure of guide plates 7, guide plates 8 and guide transmission plate 9 can be adjusted by changing the position of the two guide plates 7 in the multi-stage chute adjustment structure 6.

[0027] Furthermore, the multi-stage slide groove adjustment structure 6 includes four slide grooves 61 arranged in parallel with each other. The multi-stage slide groove adjustment structure 6 also includes two adjustment grooves 62, which are arranged through the four slide grooves 61.

[0028] Furthermore, the first guide plate 7, the second guide plate 8, and the guide transmission plate 9 are all connected by hinges 19.

[0029] Furthermore, a transmission component 10 is fixedly connected to the bottom of the flow guide plate 9. One end of the transmission component 10 is movably connected to a transmission rod 11, and the other end of the transmission rod 11 is movably connected to a turntable 12. A motor 17 is fixedly installed inside the bottom of the wear-resistant flow guide box 5. A threaded rod 15 is driven by the motor 17. A movable frame 14 is threadedly installed on the threaded rod 15. The movable frame 14 has a "C" shaped structure. A motor 2 13 is fixedly installed on the top of the movable frame 14. The motor 2 13 is driven by the turntable 12. Two sliding rods 16 are fixedly installed on one side of the inside of the wear-resistant flow guide box 5. The movable frame 14 is slidably installed on the sliding rods 16.

[0030] In this embodiment of the invention, when the two guide plates 7 slide within the multi-stage sliding groove adjustment structure 6 to adjust the inclination of the overall structure of guide plate 7, guide plate 8, and guide transmission plate 9, the motor 17 at the bottom of the anti-wear guide box 5 is activated, driving the threaded rod 15 to rotate. Since the moving frame 14 has a "C"-shaped structure and is threaded onto the threaded rod 15 and slidably mounted on the slide rod 16, the moving frame 14 moves up and down along the slide rod 16 when the threaded rod 15 rotates. When the moving frame 14 moves to a suitable position to adjust the motor 13 according to the changes in the guide plate 7, the motor 13 at the top of the moving frame 14 is activated, driving the turntable 12 to rotate. The turntable 12 drives the transmission component 10 to move up and down via the transmission rod 11, causing the guide transmission plate 9 to float up and down. The guide transmission plate 9 drives the two guide plates 8 to float up and down, changing the contact angle and force between the guide plates 8 and the material. Two guide vanes 7 slide within the multi-stage chute adjustment structure 6. Their positions within the chute 61 are adjusted using the adjustment groove 62, and with the aid of the limiting component 18, the overall tilt of the guide vane 7, guide vane 8, and guide transmission plate 9 can be adjusted. This allows for flexible adjustment of the guide structure based on factors such as the flow rate, velocity, and properties of the silica material. The floating guide vane structure prevents silica from adhering to the guide vanes and ensures that the silica falls evenly and stably onto the belt 3, avoiding concentrated impacts that could damage the belt 3.

[0031] With an adjustable flow guiding structure, the state of material falling onto belt 3 can be precisely controlled, avoiding damage to belt 3 due to material accumulation or high-speed impact, extending the service life of belt 3, reducing equipment maintenance costs and downtime, and improving production continuity and efficiency.

[0032] The tilt and floating range of the guide plate can be flexibly adjusted according to the material characteristics and production needs to achieve uniform spreading of materials on belt 3, ensure balanced force on all parts of belt 3, prevent excessive wear in some areas or belt 3 from running off-center due to uneven material distribution, improve the running stability of belt 3 and the quality of material conveying, while also making it less likely for silica to stick to the guide plate, thus improving conveying efficiency.

[0033] The multi-stage chute adjustment structure, combined with the design of a floating guide plate, allows the device to adapt to changes in the flow rate, velocity, and properties of different materials. For example, when handling large-flow lumpy materials, the inclination and floating range of the guide plate can be increased; when handling small-flow powdery materials, the parameters can be decreased to ensure stable and efficient conveying, broaden the device's application range, and enhance its versatility and adaptability.

[0034] Please see Figure 7 In one embodiment of this utility model, guide grooves 20 are fixedly installed on both sides of the inside of the wear-resistant guide box 5, and the guide grooves 20 are inclined downward.

[0035] In this embodiment of the utility model, since the size of the first guide plate 7 is smaller than that of the second flow plate 8 and the flow transmission plate 9, the downward inclined flow channel 20 can collect the silica that falls from the gap.

[0036] Please see Figure 5-6 In one embodiment of the present invention, a limiting member 18 is installed inside the slide groove 61. The limiting member 18 has a "C" shaped structure and a protrusion is provided on one side of the top of the limiting member 18.

[0037] In this embodiment of the utility model, when it is necessary to adjust the position of the first guide plate 7 in the slide groove 61, the limiting member 18 is taken out, the position of the first guide plate 7 is adjusted along the adjustment groove 62, and then the limiting member 18 is installed in the slide groove 61 to complete the adjustment of the overall structure of the first guide plate 7, the second guide plate 8 and the guide transmission plate 9.

[0038] The working principle of this utility model is as follows: When the two guide plates 7 slide in the multi-stage sliding groove adjustment structure 6 to adjust the inclination of the overall structure of guide plate 7, guide plate 8, and guide transmission plate 9, the bottom motor 17 inside the box is started to drive the threaded rod 15 to rotate, so that the moving frame 14, which is C-shaped and threaded on the threaded rod 15 and slides on the slide rod 16, moves up and down. When it reaches the appropriate position, the top motor 13 of the moving frame 14 is started to drive the turntable 12 to rotate, which drives the transmission component 10 through the transmission rod 11 to make the guide transmission plate 9 float up and down, thereby causing the guide plate 8 to change its position relative to the silica. The material contact angle and force; at the same time, the "C"-shaped structure with a protruding limiting part 18 on one side of the top can be removed. After adjusting the position of the guide plate 7 in the four parallel sliding grooves 61 through the adjustment groove 62, the limiting part 18 is installed again, so as to realize the adjustment of the overall tilt of the guide plate 7, the guide plate 8 and the guide transmission plate 9. In conjunction with the downward tilting guide groove 20, the material falling from the gap is collected. In this way, the guide structure can be flexibly adjusted according to the material flow rate, flow velocity and properties, so that the material falls evenly and steadily on the belt, avoiding damage to the belt and adhesion to the guide plate, and ensuring the stable and efficient operation of the equipment.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
