Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a cement silo anti-vibration device. Background Technology

[0002] Cement silos are specialized facilities used in industrial production for the centralized storage of bulk cement and other powdery materials. Their core function is to achieve long-term safe storage and stable supply of materials on demand through closed containers. They typically work in conjunction with automated conveying systems, metering equipment, and dust removal devices to ensure that cement is protected from moisture and impurities during storage. At the same time, they meet the needs of concrete mixing plants, precast component factories, and other scenarios for continuous material supply and precise proportioning. They are a key link in ensuring production continuity and quality control in the modern building materials industry.

[0003] Some existing cement silos, designed primarily for basic storage, often lack specialized anti-accumulation vibration structures. This leads to stubborn agglomeration and accumulation of materials on the silo walls or at the bottom of the cone due to factors such as interparticle friction, humidity changes, or design flaws in the conical discharge port. This not only reduces the effective material capacity and wastes resources but also causes problems like poor material discharge and production interruptions. These issues require inefficient methods such as manual knocking or machine shutdown for cleaning, failing to meet the modern building materials industry's demands for automated, continuous, and low-maintenance silo equipment.

[0004] Therefore, we propose a vibration prevention device for cement silos. Utility Model Content

[0005] The purpose of this invention is to provide a cement silo anti-vibration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement silo anti-vibration device, comprising: The cement silo body has a base fixedly connected to its bottom, and support columns are fixedly connected to the bottom of the base at equal intervals. A top plate is fixedly connected to the top of the cement silo body. A vibration mechanism, comprising a toothed ring, wherein a toothed ring is fixedly connected to the center of the top of the cement silo body, and transmission gears are sequentially and equidistantly meshed and installed on the outer side of the toothed ring, and a drive gear is meshed and installed on the outer side of the transmission gears. The height adjustment mechanism includes a fixed plate. The base and the top plate are symmetrically fixedly connected to the fixed plates. A sliding rod is installed between two of the fixed plates, and a threaded rod is rotatably installed between the other two fixed plates. A limit groove is opened on the outer side of the limit plate.

[0007] Preferably, the vibration mechanism further includes a driven gear, with a driven gear mounted at the bottom of the driving gear. A drive motor is mounted at the center of the top of the cement silo body, and a turntable is fixedly connected to the top output end of the drive motor. Support plates are fixedly connected at equal intervals on the outer side of the turntable. A first rotating rod is rotatably mounted inside the transmission gear, and the top of the first rotating rod is fixedly connected to the inside of the support plate. When the drive motor runs, its top output end drives the turntable to rotate. The support plates fixed at equal intervals on the outer side of the turntable rotate synchronously with the turntable. Since the top of the first rotating rod is fixedly connected to the inside of the support plate, and the bottom of the first rotating rod is rotatably connected to the inside of the transmission gear, and the outer side of the transmission gear meshes with the gear ring fixed at the center of the top of the cement silo body, the rotation of the support plate will drive the first rotating rod and the transmission gear to roll along the circumferential trajectory of the gear ring. At the same time, the outer side of the transmission gear also meshes with the driving gear, driving the driving gear to rotate during the rolling process.

[0008] Preferably, the top plate has a movable groove inside, and a movable block is slidably installed on the inner wall of the movable groove. A second rotating rod is rotatably installed inside the movable block, and both ends of the second rotating rod pass through the interior of the driving gear and the driven gear, respectively, and are rotatably connected to them. The top of the second rotating rod passes through the interior of the support plate and is fixedly connected to the support plate. The driving gear is rotatably connected to one end of the second rotating rod, and the other end of the second rotating rod passes through the interior of the driven gear and is rotatably connected to it. The middle part of the second rotating rod passes through the movable block slidably installed in the movable groove of the top plate and is fixedly connected to the support plate. Therefore, the rotation of the driving gear will drive the second rotating rod and the driven gear to rotate synchronously.

[0009] Preferably, the base has a sliding groove at its top, a sliding block is slidably installed inside the sliding groove, a connecting rod is rotatably installed inside the sliding block, and the other end of the connecting rod is fixedly connected to the driven gear. A sleeve is slidably installed on the outside of the connecting rod, and a limiting plate is fixedly connected to the outside of the sleeve. Mounting rods are fixedly connected to the top and bottom of the limiting plate at equal intervals, and a striking roller is installed on the outside of the mounting rod. When the driven gear rotates, it drives the connecting rod to rotate around its own axis. The sleeve on the outside of the connecting rod, as well as the limiting plate, mounting rod, and striking roller connected to it, rotate accordingly, combined with the circumferential motion caused by the transmission gear rolling along the gear ring.

[0010] Preferably, the height adjustment mechanism further includes a limiting ring, which is slidably installed inside the limiting groove. A meshing block is fixedly connected to the outside of the limiting ring, and the meshing block is meshed with the outside of the threaded rod. A rotating motor is installed on the top of the fixed plate, and the output end of the rotating motor passes through the inside of the fixed plate and is fixedly connected to one end of the threaded rod. When the rotating motor is started, its output end drives the threaded rod to rotate between two fixed plates symmetrically fixed to the outside of the base and the top plate. Since the meshing block is meshed with the outside of the threaded rod, and the meshing block is slidably installed in the limiting groove of the limiting plate through the limiting ring, and the limiting plate is fixedly connected to the sleeve, and the sleeve is slidably sleeved on the outside of the connecting rod, the rotation of the threaded rod will drive the meshing block to move along the axial direction of the threaded rod, thereby driving the limiting plate, the sleeve, and the connected mounting rod and striking roller to rise and fall synchronously.

[0011] Preferably, both the drive motor and the rotary motor are electrically controlled and connected by an external power supply.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Highly efficient anti-accumulation and unblocking mechanism ensures continuous production: The vibration mechanism continuously breaks the adhesion between the material and the silo wall through high-frequency micro-vibration, which can prevent powdery or granular materials from clumping and stagnating in the cone and corners of the cement silo, avoiding the problem of reduced effective material capacity and waste of resources due to accumulation. At the same time, after the height adjustment mechanism accurately locates the accumulation or blockage, it can efficiently break up the formed clumps and unblock the blocked channels with minimal amplitude, solving the inefficiency of traditional cement silos that rely on manual knocking and machine shutdown for cleaning, ensuring smooth and stable discharge, and ensuring continuous production in concrete mixing plants, precast component plants and other scenarios.

[0013] Precise adjustment reduces energy consumption and interference: The height adjustment mechanism can flexibly adjust the height and position of the striking rollers, enabling targeted operation for different areas of accumulation without large-area vibration of the entire silo, significantly reducing equipment operating energy consumption; and the design of directional action on the target area significantly reduces the spread of vibration noise to the surrounding environment, while avoiding equipment damage or structural impact caused by unnecessary vibration in non-target areas, thus improving the environmental friendliness of equipment operation and its friendliness to the surrounding environment.

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.

[0017] Please see Figure 1-4 A cement silo anti-vibration device, comprising: The cement silo body 1 has a base 2 fixedly connected to its bottom, and support columns 3 are fixedly connected to the bottom of the base 2 at equal intervals. The top plate 4 is fixedly connected to the top of the cement silo body 1. The vibration mechanism includes a toothed ring 5. The toothed ring 5 is fixedly connected to the center of the top of the cement silo body 1. Transmission gears 6 are sequentially and equidistantly meshed and installed on the outer side of the toothed ring 5. A drive gear 7 is meshed and installed on the outer side of the transmission gears 6. The height adjustment mechanism includes a fixed plate 23. The fixed plates 23 are symmetrically fixedly connected to the outer sides of the base 2 and the top plate 4. A sliding rod 24 is installed between two of the fixed plates 23. A threaded rod 25 is rotatably installed between the other two fixed plates 23. A limit groove 26 is opened on the outer side of the limit plate 20.

[0018] Please see Figure 2The vibration mechanism also includes a driven gear 8. The driven gear 8 is installed at the bottom of the driving gear 7. A drive motor 9 is installed at the top center of the cement silo body 1. A turntable 10 is fixedly connected to the top output end of the drive motor 9. Support plates 11 are fixedly connected at equal intervals on the outer side of the turntable 10. A first rotating rod 12 is rotatably installed inside the transmission gear 6, and the top of the first rotating rod 12 is fixedly connected to the inside of the support plate 11. When the drive motor 9 runs, its top output end drives the turntable 10 to rotate. The support plates 11 fixed at equal intervals on the outer side of the turntable 10 rotate synchronously with the turntable 10. Since the top of the first rotating rod 12 is fixedly connected to the inside of the support plate 11, and the bottom of the first rotating rod 12 is rotatably connected to the inside of the transmission gear 6, and the outer side of the transmission gear 6 meshes with the toothed ring 5 fixed at the top center of the cement silo body 1, when the support plate 11 rotates, it will drive the first rotating rod 12 and the transmission gear 6 to roll along the circumferential trajectory of the toothed ring 5. At the same time, the outer side of the transmission gear 6 also meshes with the driving gear 7, and the transmission gear 6 drives the driving gear 7 to rotate during the rolling process.

[0019] Please see Figure 2 The top plate 4 has a movable groove 13 inside, and a movable block 14 is slidably installed on the inner wall of the movable groove 13. A second rotating rod 15 is rotatably installed inside the movable block 14, and both ends of the second rotating rod 15 pass through the interior of the driving gear 7 and the driven gear 8, respectively, and are rotatably connected to them. The top of the second rotating rod 15 passes through the interior of the support plate 11 and is fixedly connected to the support plate 11. The interior of the driving gear 7 is rotatably connected to one end of the second rotating rod 15, and the other end of the second rotating rod 15 passes through the interior of the driven gear 8 and is rotatably connected to it. The middle part of the second rotating rod 15 passes through the movable block 14 slidably installed in the movable groove 13 of the top plate 4 and is fixedly connected to the support plate 11. Therefore, the rotation of the driving gear 7 will drive the second rotating rod 15 and the driven gear 8 to rotate synchronously.

[0020] Please see Figure 3 The base 2 has a sliding groove 16 on its top. A sliding block 17 is slidably installed inside the sliding groove 16. A connecting rod 18 is rotatably installed inside the sliding block 17, and the other end of the connecting rod 18 is fixedly connected to the driven gear 8. A sleeve 19 is slidably installed on the outside of the connecting rod 18. A limiting plate 20 is fixedly connected to the outside of the sleeve 19. Mounting rods 21 are fixedly connected to the top and bottom of the limiting plate 20 at equal intervals. A striking roller 22 is installed on the outside of the mounting rod 21. When the driven gear 8 rotates, it drives the connecting rod 18 to rotate around its own axis. The sleeve 19 on the outside of the connecting rod 18, as well as the limiting plate 20, mounting rod 21, and striking roller 22 connected to it, rotate accordingly. At the same time, this is combined with the circumferential motion caused by the transmission gear 6 rolling along the gear ring 5.

[0021] Please see Figure 4The height adjustment mechanism also includes a limiting ring 27, which is slidably installed inside the limiting groove 26. A meshing block 28 is fixedly connected to the outside of the limiting ring 27. The meshing block 28 is meshed with the outside of the threaded rod 25. A rotating motor 29 is installed on the top of the fixing plate 23, and the output end of the rotating motor 29 passes through the inside of the fixing plate 23 and is fixedly connected to one end of the threaded rod 25. When the rotating motor 29 is started, its output end drives the threaded rod 25 to rotate between two fixed plates 23 that are symmetrically fixed to the outside of the base 2 and the top plate 4. Since the meshing block 28 is meshed with the outside of the threaded rod 25, and the meshing block 28 is slidably installed in the limiting groove 26 of the limiting plate 20 through the limiting ring 27, and the limiting plate 20 is fixedly connected to the sleeve 19, and the sleeve 19 is slidably sleeved on the outside of the connecting rod 18, when the threaded rod 25 rotates, it will drive the meshing block 28 to move along the axial direction of the threaded rod 25, thereby driving the limiting plate 20, the sleeve 19 and the connected mounting rod 21 and the striking roller 22 to rise and fall synchronously.

[0022] Please see Figure 1-4 Both the drive motor 9 and the rotation motor 29 are electrically controlled and connected by an external power supply.

[0023] Working principle: To meet the material accumulation requirements at different locations, the height of the striking component is first adjusted by operating the height adjustment mechanism: the rotating motor 29 is started, and its output end drives the threaded rod 25 to rotate between two fixed plates 23 symmetrically fixed to the outside of the base 2 and the top plate 4. Since the meshing block 28 is meshed with the outside of the threaded rod 25, and the meshing block 28 is slidably installed in the limiting groove 26 of the limiting plate 20 through the limiting ring 27, and the limiting plate 20 is fixedly connected to the sleeve 19, and the sleeve 19 is slidably sleeved on the outside of the connecting rod 18, when the threaded rod 25 rotates, it will drive the meshing block 28 to move along the axial direction of the threaded rod 25, thereby driving the limiting plate 20, the sleeve 19 and the connected mounting rod 21 and striking roller 22 to rise and fall synchronously until the striking roller 22 is accurately aligned with the cone, corner and other target areas of the cement silo body 1 that are easy to accumulate or get stuck. During this period, the sliding rod 24 can play an auxiliary guiding role in the movement of the limiting plate 20 to prevent it from deviating.After the height adjustment is completed, the vibration mechanism is activated to achieve high-frequency micro-vibration: the drive motor 9 runs, and its top output end drives the turntable 10 to rotate. The support plates 11, which are fixed at equal intervals on the outer side of the turntable 10, rotate synchronously with the turntable 10. Since the top of the first rotating rod 12 is fixedly connected to the inside of the support plate 11, and the bottom of the first rotating rod 12 is rotatably connected to the inside of the transmission gear 6, and the outer side of the transmission gear 6 meshes with the toothed ring 5 fixed at the top center of the cement silo body 1, when the support plate 11 rotates, it will drive the first rotating rod 12 and the transmission gear 6 to roll along the circumferential trajectory of the toothed ring 5. At the same time, the outer side of the transmission gear 6 also meshes with the drive gear 7. During the rolling process of the transmission gear 6, the driving gear 7 is driven to rotate. The driving gear 7 is rotatably connected to one end of the second rotating rod 15. The other end of the second rotating rod 15 passes through the driven gear 8 and is rotatably connected to it. The middle part of the second rotating rod 15 passes through the movable block 14 that is slidably installed in the movable groove 13 of the top plate 4 and is fixedly connected to the support plate 11. Therefore, the rotation of the driving gear 7 will drive the second rotating rod 15 and the driven gear 8 to rotate synchronously. The driven gear 8 is fixedly connected to one end of the connecting rod 18. The other end of the connecting rod 18 passes through the sliding block 17 that is slidably installed in the sliding groove 16 of the base 2 and is rotatably connected to it. When the driven gear 8 rotates, it drives the connecting rod 18 to rotate around its own axis. The sleeve 19 on the outside of the connecting rod 18, as well as the limiting plate 20, the mounting rod 21, and the striking roller 22 connected to it, rotate accordingly. At the same time, combined with the circumferential motion brought about by the transmission gear 6 rolling along the gear ring 5, the striking roller 22, while rotating around the axis of the connecting rod 18, can also move circumferentially along the inner wall of the cement silo body 1 with the movement of the support plate 11 and the connecting rod 18, achieving all-round coverage of the silo wall. During the movement of the striking roller 22, it generates high-frequency micro-vibrations in contact with the inner wall of the cement silo, continuously breaking down powdery or granular materials. The adhesion between the material and the silo wall can prevent the material from clumping and accumulating in the target area. On the other hand, it can efficiently break up existing clumps with minimal amplitude and clear blocked channels. In addition, since the impact roller 22 only acts on the target accumulation area and the vibration is transmitted through directional transmission, the spread of noise to the surrounding environment is significantly reduced. At the same time, it avoids unnecessary vibration interference to non-target areas of the cement silo. Ultimately, it ensures smooth and stable discharge of cement from the silo without relying on manual knocking or machine shutdown for cleaning, meeting the modern building materials industry's demand for automated, continuous and low-maintenance operation of storage equipment.
