Description

[0002] An anti-clogging vibration device for aggregate bins is a specialized piece of equipment used in industrial production to solve the problem of aggregate bin blockage. Its core function is to generate controllable high-frequency vibration through a vibration source and transfer the vibration energy to the components that are in direct contact with the material. This breaks the "bridging" and "arching" structures formed by the material in the bin, while preventing the material from adhering to the bin wall due to factors such as humidity and gravity. Ultimately, it ensures that the aggregate in the bin can be smoothly discharged from the bottom outlet, avoiding production line shutdowns due to material blockage and ensuring the continuous and efficient operation of aggregate storage and transportation.

[0003] To address the aforementioned issues, existing patents offer solutions. Most existing anti-clogging vibration devices for aggregate silos are flexibly connected to the aggregate silo. This flexible connection directly contacts the flowing aggregate, and the material scouring can quickly wear down the flexible material, leading to increased maintenance costs and downtime.

[0004] To address this, a vibration device for preventing blockage in aggregate bins is proposed. Utility Model Content

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

[0027] An anti-clogging vibration device for aggregate bins includes an aggregate storage device 1, a vibration component 2 fixedly connected to the bottom of the aggregate storage device 1, a protective component 3 fixedly connected to the surface of the vibration component 2, and an auxiliary component 4 fixedly connected to the surface of the aggregate storage device 1.

[0028] The vibration assembly 2 includes a housing 201, a support sleeve 202 fixedly connected to the inner wall of the housing 201, a plurality of rigid springs 203 fixedly connected to the top of the support sleeve 202, a connecting sleeve 204 fixedly connected to the top of the plurality of rigid springs 203, a feeding hopper 205 fixedly connected to the inner wall of the connecting sleeve 204, a flexible sleeve 206 fixedly connected to the inner wall of the feeding hopper 205, the flexible sleeve 206 fixedly connected to the surface of the aggregate storage device 1, and an eccentric wheel motor 207 fixedly connected to the surface of the feeding hopper 205.

[0029] In this embodiment: An aggregate storage device 1, the core storage component, is used to store the aggregate to be conveyed, serving as the material bearing foundation for the entire device and providing a material source for subsequent anti-blocking conveying. A vibration component 2, the core anti-blocking actuator, uses vibration to break up aggregate "bridging" and "arching," ensuring smooth material flow. A protective component 3 protects key parts of the vibration component 2, reducing external interference and component wear. An auxiliary component 4 assists the vibration component 2 in achieving stable conveying and supplements the anti-blocking effect. An outer shell 201 serves as the external protection and support frame for the vibration component 2, protecting internal components such as the rigid spring 203 and the hopper 205, while also fixing the protective component 3 and the auxiliary component 4 to maintain overall structural stability. A support sleeve 202, installed on the inner wall of the outer shell 201, acts as the bottom support carrier for the rigid spring 203, providing a fixed mounting point for the rigid spring 203 and ensuring its stable force. The rigid spring 203 connects the support sleeve 202 and the connecting sleeve 204, transmitting eccentricity. The vibration energy generated by the wheel motor 207 is transmitted to the hopper 205. On the other hand, it buffers the vibration impact and prevents excessive vibration from being transmitted to the outer shell 201. By setting a connecting sleeve 204, the intermediate component connecting the rigid spring 203 and the hopper 205 is connected, and the supporting force and vibration energy of the rigid spring 203 are evenly transmitted to the hopper 205, ensuring the vibration balance of the hopper 205. By setting the hopper 205 as an aggregate conveying channel, it receives the aggregate falling from the aggregate storage device 1, and the aggregate is discharged smoothly through vibration. At the same time, a soft sleeve 2 can be installed on the inner wall. Components such as 06 and buffer sleeve 9, by setting up a soft sleeve 206, connect the feeding hopper 205 and the aggregate storage device 1, adapt to the vibration displacement between the two, avoid component damage caused by rigid connection, and at the same time cover the top of the feeding hopper 205 to prevent the aggregate from directly contacting the inner wall of the outer shell 201 through the hole at the top of the feeding hopper 205 during vibration. By setting up an eccentric wheel motor 207, the vibration power source is provided. The motor drives the eccentric wheel to rotate to generate high-frequency vibration, which is transmitted to the feeding hopper 205, providing the core power for anti-blockage.

[0030] Specifically, such as Figure 3As shown, the protective component 3 includes an electric telescopic rod 301, a connecting block 302 is fixedly connected to the bottom of the electric telescopic rod 301, a connecting rod 303 is fixedly connected to the left side of the connecting block 302, a protective cover 304 is welded to the left side of the connecting rod 303, and the protective cover 304 is movably connected to the inner wall of the outer shell 201.

[0031] Specifically, such as Figure 3 As shown, a sliding frame 305 is fixedly connected to the left side of the protective cover 304, and a bolt plate 306 is movably connected to the surface of the sliding frame 305. The bolt plate 306 is fixedly connected to the right side of the outer shell 201.

[0032] Specifically, such as Figure 3 As shown, a protective sleeve 307 is fixedly connected to the inner wall of the protective cover 304. The protective sleeve 307 is made of high-strength steel.

[0033] In this embodiment: An electric telescopic rod 301 is provided as the power source for protection and adjustment. The telescopic movement of the connecting block 302 and connecting rod 303 causes the protective cover 304 to rise and fall, controlling the opening and closing of the protection range. The connecting block 302, an intermediate connector between the electric telescopic rod 301 and the connecting rod 303, transmits the power of the telescopic rod to the connecting rod 303, causing the protective cover 304 to move synchronously. The connecting rod 303, connecting the connecting block 302 and the protective cover 304, transmits and extends the force, ensuring that the electric telescopic rod 301 can effectively control the position of the protective cover 304. The protective cover 304, the core protective component, covers the vibration assembly 2. The key area is designed to prevent external debris from entering and reduce splashing during aggregate feeding. A sliding frame 305 is installed on the left side of the protective cover 304 and works in conjunction with a bolt plate 306 to guide the lifting and lowering of the protective cover 304, ensuring smooth movement and preventing deviation. The bolt plate 306 is fixed to the right side of the outer shell 201 and is movably connected to the sliding frame 305. It serves as both the mounting carrier for the sliding frame 305 and a guide to limit the movement trajectory of the protective cover 304, ensuring accurate protective positioning. A protective sleeve 307, made of high-strength steel, is installed on the inner wall of the protective cover 304 to enhance its wear resistance and impact resistance, extending its service life.

[0034] Specifically, such as Figure 4 As shown, the auxiliary component 4 includes a support plate 401, a servo motor 402 is bolted to the top of the support plate 401, and a rotating disk 403 is fixedly connected to the bottom of the servo motor 402.

[0035] Specifically, such as Figure 4 As shown, a protective disk 404 is fixedly connected to the top of the rotating disk 403, and the protective disk 404 is movably connected to the bottom of the outer casing 201. The support plate 401 is fixedly connected to the front side of the outer casing 201.

[0036] In this embodiment: A support plate 401 is fixed to the front side of the outer casing 201 to serve as the mounting carrier for the servo motor 402, providing stable support for the motor and ensuring that the servo motor 402 does not shake during operation. The servo motor 402 serves as an auxiliary power source to drive the rotating disk 403 to rotate, thereby adjusting the angle of the protective disk 404. As the servo motor 402 adjusts its rotation angle, the rotating disk 403 is protected by the protective disk 404. If any residual aggregate from inside the hopper 205 falls, the protective disk 404 protects the top of the rotating disk 403, preventing the aggregate from impacting the protective disk 404.

[0037] Specifically, such as Figure 4 , Figure 6 As shown, an auxiliary frame 5 is fixedly connected to the right side of the outer casing 201, and an auxiliary rod 6 that works with the auxiliary frame 5 is fixedly connected to the top of the protective plate 404. A limit block 7 is fixedly connected to the top of the auxiliary rod 6, and a soft pad 8 is fixedly connected to the bottom of the limit block 7.

[0038] Specifically, such as Figure 5 As shown, a buffer sleeve 9 is fixedly connected to the inner wall of the hopper 205, and a wear-resistant cover 10 is fixedly connected to the inner wall of the buffer sleeve 9.

[0039] In this embodiment: An auxiliary frame 5 is fixed to the right side of the outer casing 201, serving as a support and guide for the auxiliary rod 6, providing a stable mounting base for the auxiliary rod 6 and restricting its movement direction. The auxiliary rod 6 engages with the surface of the auxiliary frame 5, assisting in limiting the rotation of the rotating disk 403. A limiting block 7 is fixedly connected to the top of the auxiliary rod 6, sharing the support for the servo motor 402 when the rotating disk 403 obstructs the bottom of the outer casing 201. A soft pad 8 is fixed to the limiting block. At the bottom, when the limiting block 7 contacts the auxiliary frame 5, it acts as a buffer to reduce collision noise and component wear, and protect the limiting block 7 and the auxiliary frame 5. By setting a buffer sleeve 9, which is installed on the inner wall of the feeding hopper 205, the material has a certain elasticity and can buffer the impact of aggregate falling on the inner wall of the feeding hopper 205, reducing the direct wear of aggregate on the feeding hopper 205. By setting a wear-resistant cover 10, which is fixed on the inner wall of the buffer sleeve 9, the material is a highly wear-resistant material that directly contacts the flowing aggregate, resists the wear caused by aggregate scouring, and extends the service life of the inner wall of the feeding hopper 205.

[0040] Working Principle: When the aggregate silo anti-clogging vibration device is working, the aggregate storage device 1 first carries the aggregate to be conveyed. The aggregate enters the discharge hopper 205 of the vibration component 2 from its bottom. The eccentric wheel motor 207 in the vibration component 2 is started, and the motor drives the eccentric wheel to rotate, generating high-frequency vibration. The vibration energy is transmitted to the internal aggregate through the discharge hopper 205. At the same time, the connecting sleeve 204 evenly disperses the vibration. In conjunction with the rigid spring 203 at the top of the support sleeve 202, the vibration impact is buffered, thereby breaking the "bridging" and "arching" structure formed by the aggregate due to humidity and gravity during the fall, ensuring smooth movement of the aggregate. The soft sleeve 206 on the inner wall of the discharge hopper 205 adapts to the vibration displacement between the aggregate storage device 1 and the discharge hopper 205, preventing damage to the rigid connection. It can also cover the top of the discharge hopper 205 to prevent the aggregate from directly contacting the inner wall of the outer shell 201. The protective component 3 works synchronously. In operation, the electric telescopic rod 301 drives the protective cover 304 to rise and fall along the sliding frame 305 on the bolted plate 306 via the connecting block 302 and the connecting rod 303, adjusting the protection range. The high-strength steel protective sleeve 307 on the inner wall can block external debris from entering the vibration component 2, reducing the wear of the components caused by aggregate splashing. In the auxiliary component 4, the servo motor 402 on the support plate 401 drives the rotating disk 403 and the top protective disk 404 to rotate. The protective disk 404 cooperates with the bottom of the outer shell 201 to receive the aggregate that may fall from the hopper 205 and prevent it from impacting the rotating disk 403. The auxiliary frame 5 on the right side of the outer shell 201 engages with the auxiliary rod 6 on the top of the protective disk 404. The limiting block 7 and the bottom soft pad 8 can not only provide support for the rotating disk 403, but also buffer the collision during contact, further ensuring the stable operation of the device, and ultimately achieving non-blocking and continuous conveying of aggregate.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
