Description

Technical Field

[0001] This utility model relates to the field of dustproof sealing equipment technology, and more specifically, to a high-efficiency dust removal grain feeding port sealing mechanism. Background Technology

[0002] Dust removal and sealing of grain feeding ports are primarily for reducing dust pollution, ensuring production safety, and improving operational efficiency. During the feeding process, friction between grain particles and airflow easily generate large amounts of dust, which not only pollutes the environment and harms worker health but may also trigger dust explosions. Simultaneously, dust escape leads to raw material loss, impacting economic benefits. Sealing prevents external impurities and moisture from entering, ensuring grain storage quality and reducing the risk of pests and mold. Therefore, dust removal and sealing are indispensable environmental and safety measures in grain processing and storage.

[0003] Traditional grain feeding ports typically use simple covers or manual sealing methods. Existing dust removal equipment is often separate from the feeding port, requiring additional dust collection devices, which takes up space and is inconvenient to operate. Dust removal and sealing are usually designed as two independent systems, requiring manual adjustment or replacement of parts when switching, increasing operational complexity, affecting production efficiency, lacking automated control, and unable to achieve rapid conversion from dust removal to sealing, making it difficult to meet the high-efficiency and clean production requirements of modern grain processing.

[0018] Compared with existing technologies, this utility model provides a highly efficient dust removal sealing mechanism for grain feeding ports, which has the following beneficial effects:

[0019] This high-efficiency dust removal grain feeding port sealing mechanism works as follows: When dust removal is required at the feeding port, a servo motor is started, driving the transmission worm gear to rotate. This rotation causes the transmission worm wheel to rotate at a certain angle, resulting in the support plate rotating and moving the dust removal fan and dust removal hood to the upper side of the feeding port and aligning them. Then, by controlling the rotation of the bidirectional threaded rod, the two transmission blocks are moved away from each other, causing the support plate to descend and fit against the top of the feeding port. The dust removal fan and dust removal hood then draw in the dust and air from inside the feeding port and discharge it, completing the dust removal process. Finally, the bidirectional threaded rod is controlled to rotate... The two transmission blocks are brought closer together, causing the support plate to rise. Then, the transmission worm gear is controlled to rotate, driving the transmission worm wheel to rotate a certain angle, causing the support plate to move the sealing plate to the upper side of the feeding port. Finally, the bidirectional threaded rod is controlled to rotate, causing the two transmission blocks to move away from each other, so that the support plate seals the feeding port. This system integrates efficient dust removal and sealing functions. Through the coordinated control of the lifting and rotating mechanisms, the dust removal and sealing functions can be automatically and quickly switched without manual intervention, reducing operational complexity, significantly improving work efficiency, and meeting the high-efficiency and clean production requirements of modern grain processing.

Detailed Implementation

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

[0027] Example:

[0028] Please see Figures 1-4 A high-efficiency dust removal grain feeding port sealing mechanism, comprising:

[0029] The mounting support box 1 is rotatably connected between the inner walls of the two sides of the mounting support box 1. Two transmission blocks 9 are threadedly connected to the two transmission blocks 9. Transmission rods 10 are rotatably connected to the top of the two transmission blocks 9. Two lifting rods 11 slide through the top of the mounting support box 1. Lifting plates 12 are fixedly connected to the lower ends of the two lifting rods 11. The lifting plates 12 are rotatably connected to the two transmission rods 10.

[0030] Function switching control box 2 is fixedly connected to the upper ends of the two lifting rods 11. A transmission worm gear 16 is rotatably connected between the upper and lower inner walls of the function switching control box 2, and a transmission worm 17 is rotatably connected between the two inner walls of the function switching control box 2. The transmission worm 17 meshes with the transmission worm gear 16.

[0031] Support plate 3 is rotatably connected to the top of function switching control box 2, and support plate 3 is fixedly connected to transmission worm gear 16 through rotating shaft rod. Dust removal component is fixedly installed on the top of support plate 3.

[0032] In a specific embodiment of this utility model, a square opening is provided on the top of the support plate 3, corresponding to the dust removal hood 6. Another square area of ​​the support plate 3 is used to fit against the top of the feeding port 4 to seal the feeding port 4. By controlling the rotation of the bidirectional threaded rod 8, the two transmission blocks 9 are driven to move relatively closer or relatively farther apart. When the two transmission blocks 9 move relatively closer, the lifting plate 12 is driven to rise through the two transmission rods 10, which in turn drives the function switching control box 2 to rise through the two lifting rods 11, thereby driving the support plate 3 to rise. When the two transmission blocks 9 move relatively farther apart, the lifting plate 12 is driven to fall through the two transmission rods 10, which in turn drives the function switching control box 2 to fall through the two lifting rods 11, thereby driving the support plate 3 to fall. When the feeding port 4 needs dust removal, the transmission worm gear 17 is controlled to rotate, which drives the transmission worm wheel 16 to rotate at a certain angle, causing the support plate 3 to rotate and move the dust removal assembly to the upper side of the feeding port 4. Correspondingly, by controlling the rotation of the bidirectional threaded rod 8, the two transmission blocks 9 are moved away from each other, thereby causing the support plate 3 to descend and fit against the top of the feeding port 4. The dust removal component sucks in the dust and air inside the feeding port 4 and then discharges it, completing the dust removal step of the feeding port 4. Then, by controlling the rotation of the bidirectional threaded rod 8, the two transmission blocks 9 are moved closer together, causing the support plate 3 to rise. Then, the transmission worm gear 17 is rotated, causing the transmission worm wheel 16 to rotate a certain angle, so that the other square area of ​​the support plate 3 moves to the upper side of the feeding port 4. Finally, by controlling the rotation of the bidirectional threaded rod 8, the two transmission blocks 9 are moved away from each other, so that the support plate 3 seals the feeding port 4. This integrates efficient dust removal and sealing functions. Through the coordinated control of the lifting and rotating mechanisms, the dust removal and sealing functions can be automatically and quickly switched without manual intervention, reducing the complexity of operation, significantly improving the efficiency of operation, and meeting the high-efficiency and clean production requirements of modern grain processing.

[0033] Specifically, the dust removal assembly includes a dust removal fan 5 and a dust removal hood 6. The dust removal hood 6 is fixedly connected to the top of the support plate 3, and the dust removal fan 5 is fixedly installed on the top of the support plate 3. The input end of the dust removal fan 5 is fixedly connected to the dust removal hood 6 through a duct.

[0034] In this embodiment, the dust removal fan 5 is a common dust removal device on the market. After the dust removal fan 5 is started, a negative pressure is generated at the inlet, and the dust inside the feeding port 4 is sucked in along with the air through the dust removal hood 6 and then discharged.

[0035] Specifically, a sealing plate 7 is fixedly connected to the bottom of the support plate 3.

[0036] In this embodiment, the sealing plate 7 is embedded in the top opening of the feeding port 4 to further improve the sealing performance.

[0037] Specifically, a drive motor 14 is fixedly installed on one outer surface of the mounting support box 1, and the output end of the drive motor 14 is fixedly connected to the bidirectional threaded rod 8.

[0038] In this embodiment, the drive motor 14 is started by controlling it to drive the bidirectional threaded rod 8 to rotate.

[0039] Specifically, two limiting rods 13 are fixedly connected between the inner walls of the two sides of the mounting support box 1, and each transmission block 9 is slidably sleeved on the two limiting rods 13.

[0040] In this embodiment, the two limiting rods 13 keep the two transmission blocks 9 stable during relative motion.

[0041] Specifically, a servo motor 15 is fixedly installed on one outer surface of the function switching control box 2, and the output end of the servo motor 15 is fixedly connected to the transmission worm gear 17.

[0042] In this embodiment, the servo motor 15 is started to drive the transmission worm gear 17 to rotate.

[0043] Working principle: By controlling the start of the drive motor 14, the bidirectional threaded rod 8 is rotated, thereby driving the two transmission blocks 9 to move closer or further apart. When the two transmission blocks 9 move closer, they drive the lifting plate 12 to rise via the two transmission rods 10, which in turn drives the function switching control box 2 to rise via the two lifting rods 11, thereby driving the support plate 3 to rise. When the two transmission blocks 9 move further apart, they drive the lifting plate 12 to fall via the two transmission rods 10, which in turn drives the function switching control box 2 to fall via the two lifting rods 11, thereby driving the support plate 3 to fall. When dust removal is required at the feeding port 4, the servo motor 15 is started, driving the transmission worm gear 17 to rotate, which in turn drives the transmission worm wheel 16 to rotate at a certain angle, causing the support plate 3 to rotate and move the dust removal fan 5 and dust removal hood 6 to the upper side of the feeding port 4 and align them. Then, by controlling the rotation of the bidirectional threaded rod 8, the two transmission blocks 9 move closer or further apart. The moving blocks 9 move away from each other, causing the support plate 3 to descend and fit against the top of the feeding port 4. The dust removal fan 5 and the dust removal hood 6 draw in the dust and air inside the feeding port 4 and then discharge it, completing the dust removal step of the feeding port 4. Then, the bidirectional threaded rod 8 is controlled to rotate, causing the two transmission blocks 9 to move closer together, making the support plate 3 rise. Then, the transmission worm gear 17 is controlled to rotate, causing the transmission worm wheel 16 to rotate a certain angle, so that the support plate 3 moves the sealing plate 7 to the upper side of the feeding port 4. Finally, the bidirectional threaded rod 8 is controlled to rotate, causing the two transmission blocks 9 to move away from each other, so that the support plate 3 seals the feeding port 4. This system integrates efficient dust removal and sealing functions. Through the coordinated control of the lifting and rotating mechanisms, the dust removal and sealing functions can be automatically and quickly switched without manual intervention, reducing the complexity of operation, significantly improving the efficiency of operation, and meeting the needs of efficient and clean production in modern grain processing.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
