Description

Technical Field

[0001] This utility model relates to the field of curved coal hopper technology, specifically a self-cleaning, anti-clogging, internally divided, shrimp-shaped curved coal hopper. Background Technology

[0002] In the industrial production fields of coal mining, processing, storage and transportation, coal hoppers are key equipment for coal transfer and transportation. Their smooth operation is crucial to ensuring the stability and continuity of the production process. In order to solve the problem that traditional integrated coal hoppers are prone to blockage due to coal sticking and accumulation, the industry has gradually adopted a structural design that divides the inside of the coal hopper into multiple independent compartments.

[0003] However, in actual production, coal itself has a certain degree of caking, and it is easily affected by factors such as humidity and pressure during storage and transportation. Coal sticking and accumulation are very common, which leads to varying degrees of blockage on the inner walls of the internal compartment pipes.

[0004] When localized coal adhesion, accumulation, and blockage occur in the internal compartment pipes, the industry still relies on manual cleaning to solve the blockage problem. Manual cleaning not only consumes a lot of manpower and time, seriously affecting production efficiency, but also requires workers to operate in the relevant pipe area during the cleaning process. During this process, there is a high risk of safety accidents such as coal pile collapse burying people and dust poisoning, which pose a serious threat to the lives of workers and cannot meet the requirements of modern industrial production for safety and efficiency.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this invention is to provide a self-cleaning, anti-clogging, internally divided, shrimp-shaped curved coal hopper to solve the problems mentioned in the background art.

[0007] To solve the above technical problems, the present invention provides a self-cleaning, anti-clogging, internally divided, shrimp-shaped curved coal hopper, including a connecting ring, a support rod fixedly installed at the bottom of the inner wall of the connecting ring, a motor fixedly installed at the center of the inner wall of the support rod, an elliptical ring fixedly installed at the top drive end of the motor, and ejection mechanisms fixedly installed on both sides of the connecting ring, with the two ejection mechanisms symmetrically distributed. The ejection mechanism includes a fixed plate, a sleeve, an ejection rod, an elastic airbag, a stop post, a storage spring, and a return spring. The fixed plate is fixedly connected to the inner wall of the connecting ring. The sleeve is slidably installed inside the fixed plate. The ejection rod is slidably inserted inside the sleeve. The elastic airbag is fixedly installed on the fixed plate. The stop post is fixedly installed on the top of the elastic airbag. The two ends of the storage spring are fixedly connected to the sleeve and the ejection rod, respectively. The two ends of the return spring are fixedly connected to the sleeve and the fixed plate, respectively.

[0008] Furthermore, the upper end of the inner wall of the fixed plate is provided with an ejection groove, and the lower end of the inner wall is provided with a sliding groove. The inner wall of the ejection groove and the sliding groove away from the center of the connecting ring is provided with a connecting groove perpendicularly. The sleeve is slidably installed on the inner wall of the end of the ejection groove near the center of the connecting ring. The end of the ejection rod away from the sleeve extends out of the end of the fixed plate, and an impact plate is fixedly installed at this end. The end of the ejection rod away from the impact plate is fixedly installed with an abutment plate. The abutment plate is located inside the connecting ring and is arranged opposite to the elliptical ring.

[0009] Furthermore, the elastic airbag is fixedly installed on the top of the inner wall of the connecting groove, the inner wall of the stop post is provided with an oblique unlocking groove, the end of the release rod away from the connecting plate can be inserted into the oblique unlocking groove, the stop post is located in the connecting groove and is arranged opposite to the ejection rod, the outer wall of the ejection rod is fixedly fitted with an ejection ring, the ejection ring is located on the side of the sleeve away from the impact plate, the top of the stop post and the bottom of the ejection ring can abut against each other, and the energy storage spring is sleeved on the outside of the ejection rod and located between the sleeve and the ejection ring.

[0010] Furthermore, a connecting plate is fixedly installed on the bottom of the outer wall of the end of the sleeve near the inner wall of the connecting ring, and a release rod is fixedly installed on the inner wall of the connecting plate. The release rod slides through the groove and its extension direction is consistent with the sliding direction of the sleeve. The reset spring is sleeved on the outside of the sleeve, one end of which is fixedly connected to the end of the sleeve away from the storage spring, and the other end is fixedly connected to the outer wall of the fixing plate near the center of the connecting ring.

[0011] Furthermore, the connecting ring is threadedly connected to two abutment plates on its outer wall away from the ejection mechanism, and the two abutment plates are symmetrically distributed with the two ejection mechanisms.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By driving the elliptical ring to rotate through the motor, and coordinating with the periodic ejection action of the ejection mechanism, the impact plate generates continuous and powerful vibrations that strike the inner wall of the coal pipe in the compartment. This effectively breaks down the cohesive force of the coal and prevents coal from accumulating and clogging the compartment or pipe wall. Compared with traditional anti-clogging measures, the vibration impact is stronger and more precise, thus improving the anti-clogging effect. 2. The combination of the energy storage spring and the return spring in the ejection mechanism, along with the unlocking structure of the stop and release rod, ensures a smooth and continuous ejection and reset process, guaranteeing long-term stable operation of the device. Meanwhile, the abutment plate on the outer wall of the connecting ring is connected by threads to fix pipes of different diameters, making it highly adaptable and easy to install.

[0015] 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.

[0016] Please see Figures 1-4This utility model provides a technical solution: a self-cleaning, anti-clogging, internally divided, shrimp-shaped curved coal hopper, including a connecting ring 1. A support rod 2 is fixedly installed at the bottom of the inner wall of the connecting ring 1. A motor 6 is fixedly installed at the center of the inner wall of the support rod 2. An elliptical ring 3 is fixedly installed at the top drive end of the motor 6. Here, the eccentric rotation characteristic of the elliptical ring 3 is used to trigger the ejection action, replacing the traditional cam or linkage transmission method, resulting in a more compact structure. Ejection mechanisms 4 are fixedly installed on both sides of the connecting ring 1, and the two ejection mechanisms 4 are symmetrically distributed. The connecting ring 1 serves as a basic frame, providing a stable mounting carrier for the support rod 2 and the ejection mechanisms 4. The motor 6 is fixed to the center of the connecting ring 1 through the support rod 2, ensuring that the elliptical ring 3 can symmetrically drive the ejection mechanisms 4 on both sides when rotating, achieving synchronous anti-clogging on both sides of the hopper wall. The ejection mechanism 4 includes a fixed plate 41, a sleeve 42, an ejection rod 43, an elastic airbag 44, a stop post 45, a storage spring 46, and a return spring 47. The fixed plate 41 is fixedly connected to the inner wall of the connecting ring 1, and the sleeve 42 is slidably installed on the inner wall of the connecting ring 1. Inside the fixed plate 41, the ejector rod 43 slides through the sleeve 42. Through the nested sliding design of the fixed plate 41, sleeve 42, and ejector rod 43, combined with the synergistic effect of the double springs 46 and 47, and the unlocking assembly consisting of the elastic airbag 44 and the stop post 45, the precise accumulation and instantaneous release of impact force are achieved. The elastic airbag 44 is fixedly installed on the fixed plate 41, and the stop post 45 is fixedly installed on the top of the elastic airbag 44. The elastic airbag 44 and the stop post 45 are combined as the unlocking component. The elastic cushioning of the elastic airbag 44 is used to achieve the smooth downward movement and reset of the stop post 45. Compared with the rigid unlocking structure, it is more durable. The two ends of the elastic spring 46 are fixedly connected to the sleeve 42 and the ejector rod 43 respectively, and the two ends of the reset spring 47 are fixedly connected to the sleeve 42 and the fixed plate 41 respectively. This ensures that the device can operate stably for a long time without frequent maintenance. It can be directly adapted to the continuous operation requirements of coal hopper walls in industrial scenarios. After installation, it can operate automatically, greatly reducing the cost of manual intervention.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a self-cleaning, anti-clogging, internally divided, shrimp-shaped curved coal hopper, including a connecting ring 1 with two abutment plates 5 threadedly connected to the outer wall away from the ejector mechanism 4. By rotating the abutment plates 5, the device can be adapted to coal hopper walls with different inner diameters, greatly enhancing the versatility and installation flexibility of the device. The two abutment plates 5 and the two ejector mechanisms 4 are symmetrically distributed. This symmetrical layout can ensure that the device is balanced under force after it is fixed, effectively preventing the device from shifting during vibration and improving the operational stability of the device.

[0018] Please see Figures 1-4This utility model provides a technical solution: a self-cleaning, anti-clogging, internally divided, curved coal hopper, including a fixed plate 41 with an ejection groove 411 at the upper end of the inner wall and a sliding groove 412 at the lower end of the inner wall. A connecting groove 413 is perpendicularly formed on the inner wall of the ejection groove 411 and the sliding groove 412 on the side away from the center of the connecting ring 1. The ejection groove 411, the sliding groove 412, and the connecting groove 413 formed on the fixed plate 41 provide precise installation and movement space for components such as the sleeve 42, the release rod 422, and the elastic airbag 44. The sleeve 42 is slidably installed on the inner wall of the end of the ejection groove 411 near the center of the connecting ring 1. The ejection groove 411 can limit the sliding trajectory of the sleeve 42. The sliding groove 412 can guide the synchronous movement of the release rod 422. The connecting groove 413 provides an installation base for the elastic airbag 44 and the stop post 45. This groove layout makes the movement of each component non-interfering and coordinated, further optimizing the structural compactness and operational reliability of the ejection mechanism 4.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a self-cleaning, anti-clogging, internally divided, curved coal hopper, including a catapult rod 43 with one end extending from the end of the fixed plate 41 away from the sleeve 42, and an impact plate 432 fixedly installed at this end. By setting the impact plate 432, the contact area with the hopper wall is increased, making the vibration impact more effective. An abutment plate 431 is fixedly installed at the end of the catapult rod 43 away from the impact plate 432. The abutment plate 431 is located inside the connecting ring 1 and is arranged opposite to the elliptical ring 3. This relative arrangement ensures that the elliptical ring 3 can stably trigger the sliding of the catapult rod 43 when rotating, so as to achieve the accuracy of power transmission.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a self-cleaning, anti-blocking, internally divided, curved coal hopper, including a connecting plate 421 fixedly installed at the bottom of the outer wall of the end of the sleeve 42 near the inner wall of the connecting ring 1. A release rod 422 is fixedly installed on the inner wall of the connecting plate 421. The release rod 422 slides through the sliding groove 412, and its extension direction is consistent with the sliding direction of the sleeve 42. This structural design allows the sleeve 42 to drive the release rod 422 to slide in the sliding groove 412 through the connecting plate 421, so that the movement of the release rod 422 is strictly synchronized with the sliding of the sleeve 42. This ensures that the release rod 422 can accurately insert into the inclined unlocking groove 451 of the stop post 45 when the sleeve 42 moves to a specific position, providing a reliable triggering condition for the subsequent unlocking and ejection action, and ensuring the timing of the entire ejection mechanism 4.

[0021] Please see Figures 1-4This utility model provides a technical solution: a self-cleaning, anti-clogging, internally divided, curved coal hopper, including an elastic airbag 44 fixedly installed on the top of the inner wall of a connecting groove 413, which is connected to a stop post 45 in the connecting groove 413. The inner wall of the stop post 45 is provided with an oblique unlocking groove 451, which is adapted to a release rod 422. The end of the release rod 422 away from the connecting plate 421 can be inserted into the oblique unlocking groove 451. When the release rod 422 is inserted, it can push the stop post 45 down through the oblique structure and compress the elastic airbag 44, realizing a mechanical triggering and elastic buffering unlocking method, avoiding component wear caused by hard contact. The stop post 45 is located in the connecting groove 413 and is set opposite to the ejector rod 43. At the same time, the reset function of the elastic airbag 44 ensures that the stop post 45 can quickly return to its original position, improving the durability and cycle efficiency of the mechanism.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a self-cleaning, anti-clogging, internally divided, curved coal hopper, including an ejector rod 43 with an ejector ring 433 fixedly sleeved on its outer wall. The ejector ring 433 is located on the side of the sleeve 42 away from the impact plate 432. The ejector ring 433 is fixed to the ejector rod 43 and abuts against the stop post 45. The top of the stop post 45 and the bottom of the ejector ring 433 can abut against each other. The blocking of the ejector ring 433 by the stop post 45 can ensure sufficient accumulation of potential energy. A storage spring 46 is sleeved on the outside of the ejector rod 43 and located between the sleeve 42 and the ejector ring 433. The storage spring 46 is sleeved on the ejector rod 43 and connects the sleeve 42 and the ejector ring 433, so that when the ejector rod 43 slides, the storage spring 46 can stably accumulate elastic potential energy. When the stop post 45 is unlocked, the elastic release of the storage spring 46 can directly drive the ejector rod 43 to move rapidly.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a self-cleaning, anti-clogging, internally divided, shrimp-shaped curved coal hopper, including a return spring 47 sleeved on the outside of the sleeve 42. One end of the return spring 47 is fixedly connected to the end of the sleeve 42 away from the energy storage spring 46, and the other end is fixedly connected to the outer wall of the fixing plate 41 near the center of the connecting ring 1. The return spring 47 is sleeved on the outside of the sleeve 42 and connects the sleeve 42 and the fixing plate 41. When the sleeve 42 slides with the ejector rod 43, it can simultaneously accumulate return potential energy. When the elliptical ring 3 disengages from the contact, the return spring 47 can quickly drive the sleeve 42 and the ejector rod 43 back to their original positions, preparing for the next ejection cycle, ensuring that the device can achieve continuous and periodic vibration impact, and improving the sustainability of the anti-clogging effect.

[0024] Working principle: First, by rotating the two abutment plates 5 on the outer wall of the connecting ring 1, the abutment plates 5 are brought into contact with the inner wall of the coal pipeline to fix the entire device. Then, the motor 6, which is fixedly installed on the inner wall at the center of the support rod 2, is started. The motor 6 drives the elliptical ring 3 at the top to rotate. Utilizing the eccentric structure of the elliptical ring 3, when the protrusions at both ends of the elliptical ring 3 abut against the abutment plate 431 at the end of the ejector rod 43, the abutment plate 431 is pushed, causing the ejector rod 43 to slide away from the inner wall of the pipeline. During this process, the spring-loaded mechanism fixedly sleeved on the outer wall of the ejector rod 43... As the ejection ring 433 moves, the energy storage spring 46 at the side end of the connecting sleeve 42 and the side wall of the ejection ring 433 is compressed and accumulates elastic potential energy. At the same time, the ejection rod 43 drives the sleeve 42, which is slidably installed in the ejection groove 411 of the fixed plate 41, to slide synchronously. This causes the return spring 47, which is connected to the outer wall of the fixed plate 41 at the end of the sleeve 42 away from the energy storage spring 46, to undergo elastic deformation and accumulate return potential energy. Furthermore, the connecting plate 421 at the bottom of the outer wall of the end of the sleeve 42 near the inner wall of the connecting ring 1 will drive its inner wall to be fixedly installed. The release rod 422 slides within the groove 412 of the fixed plate 41. When the release rod 422 slides into the inclined unlocking groove 451 inserted into the inner wall of the stop post 45, the release rod 422 pushes the stop post 45 downward, compressing the elastic airbag 44 fixedly connected to the top of the inner wall of the connecting groove 413. At this time, the stop post 45 disengages from the ejection ring 433, and the energy storage spring 46 releases its elastic potential energy instantaneously, pushing the ejection ring 433 to drive the ejection rod 43 to slide rapidly towards the inner wall of the pipe, thereby moving the ejection rod 43 away from the sleeve. One end of the tube 42 extends out of the impact plate 432 at the end of the fixed plate 41 and impacts the inner wall of the pipe. As the elliptical ring 3 continues to rotate, its protrusion disengages from the abutment plate 431. The reset spring 47 releases potential energy to drive the sleeve 42 and the ejector rod 43 to reset. The release rod 422 exits from the inclined unlocking groove 451. The elastic airbag 44 pushes the stop post 45 to move upward and reset, waiting for the next protrusion of the elliptical ring 3 to contact the abutment plate 431. The above-mentioned energy storage and ejection process is repeated to achieve periodic vibration impact on the inner wall of the pipe.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
