It has good sealing performance, can effectively prevent material leakage, reduce dust flying, protect the environment and ensure accurate material transportation. An adjustment device is required to control the arc gate when it is opened and closed.

[0003] When using the arc gate, materials often stick to the surface of the arc gate (such as flour, starch, mineral powder, etc.). These stuck materials will affect the smoothness of material discharge, and the lower arc gate adjustment mechanism of the existing technology can only rotate the arc gate, and cannot clean the arc gate during rotation. At the same time, the existing single-door silo arc gate is opened and closed by a hydraulic cylinder and can only rotate in one direction, which will cause different surface wear of the arc gate (the flow rate needs to be controlled when the silo is discharged, the arc gate is not fully opened, and the parts where the arc gate and the lower part of the silo often rub against each other are more seriously worn), increasing the replacement frequency. Therefore, a technical measure is proposed to solve the problem that the lower arc gate adjustment mechanism of the existing technology can only rotate the arc gate, and cannot clean the arc gate during rotation, affecting the smoothness of material discharge, and the single-door silo arc gate is opened and closed by a hydraulic cylinder and can only rotate in one direction, which will cause different surface wear of the arc gate and increase the replacement frequency.

Thanks to the coordinated use of the motor, the rotating rod and the worm, the two-way rotation of the arc door of the single-door hopper is achieved, thereby preventing serious wear on one side of the arc door, thereby maintaining the same degree of wear on the upper surface of the arc door, improving the service life of the arc door, and reducing the replacement frequency. At the same time, thanks to the setting of the cleaning component, the arc door can be cleaned during rotation, preventing the occurrence of sticking materials that affect the smoothness of discharge, ensuring normal discharge, and the movably arranged scraper is convenient for cleaning and maintains the cleaning effect.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] This specific embodiment is a silo discharge port arc door adjustment device, and its structural diagram is as follows Figure 1 、 Figure 2 、 Figure 3 As shown, it includes a feed box 1, a cleaning component 2 and an arc door 15. A base frame 6 is installed at the lower end of the side of the feed box 1, a mounting plate 5 is installed on the base frame 6, and two groups of symmetrically distributed support plates 9 are installed on the upper surface of the mounting plate 5. A motor 11 is installed on the side of one group of support plates 9. The motor 11 is connected to a rotating rod 10. There are two groups of rotating rods 10. The two groups of rotating rods 10 are rotatably connected to the support plates 9. A worm 8 is connected between the two groups of rotating rods 10. A guide part 3 is installed at the lower part of the feed box 1, and the guide part 3 is retracted toward the bottom. The lower end of the guide portion 3 is provided with a discharge portion 4, the lower portion of the discharge portion 4 is arc-shaped, the discharge portion 4 is slidably adapted to the arc door 15, and there are two groups of cleaning components 2, which are fixedly mounted on the side of the discharge portion 4. When the cleaning components 2 and the arc door 15 rotate, the inner surface contacts, the worm 8 is engaged with the gear 7, the gear 7 is connected to the connecting rod 12, and a vertical plate 13 is installed in the middle position of the upper surface of the mounting plate 5. The vertical plate 13 is rotatably connected to the connecting rod 12, and the other end of the connecting rod 12 is rotatably connected to the rotating seat 1 7. The rotating seat 17 is fixedly mounted on the side of the discharge part 4, and the connecting rod 12 is fixedly penetrated by a rotating plate 16. The lower end of the rotating plate 16 is installed with a connecting plate 14. The side of the connecting plate 14 is fixedly connected to the arc gate 15. When the arc gate 15 is actually used to control the discharge of materials, the starting motor 11 drives the rotating rod 10 to rotate. The rotating rod 10 rotates to drive the worm 8 to rotate. The worm 8 rotates to drive the gear 7 to rotate. The gear 7 rotates to drive the connecting rod 12 to rotate. The connecting rod 12 rotates to drive the rotating plate 16 to rotate. The rotating plate 16 rotates to drive the connecting plate 14 to rotate. The connecting plate 14 rotates to drive the arc gate 15 to rotate. When the arc gate 15 rotates to the appropriate position (the arc gate 15 can be fully opened or partially opened to control the speed of material falling), the limit of the silo is released, and the material falls. When the arc gate 15 needs to be moved in the opposite direction, the starting motor 11 is reversed to drive the arc gate 15 to rotate in the opposite direction to discharge materials. When the arc gate 15 rotates, the cleaning component 2 scrapes and cleans the material adhering to the inner surface of the arc gate 15.

[0023] Reference Figure 1 、 Figure 3 、 Figure 4As shown, the cleaning assembly 2 includes a top plate 201, which is threaded with multiple groups of evenly distributed bolts 202, and the top plate 201 is fixedly connected to the side of the discharge part 4 through the bolts 202. A limit plate 203 is installed at the lower part of the top plate 201, and a T-shaped slot 204 is provided on the side of the limit plate 203. The T-shaped slot 204 is movably engaged with a T-shaped block 206 and a magnetic plate 207. A scraper 205 is installed on the side of the T-shaped block 206. The scraper 205 is arranged in an arc shape. When the scraper 205 rotates, the inner surface of the arc door 15 contacts the scraper 205. When the arc door 15 rotates, the inner surface contacts the scraper 205 (when the cleaning assembly 2 is set, the scraper 205 can clean half of the area of ​​the arc door 15, Two sets of scrapers 205 can clean the arc gate 15), the scraper 205 scrapes off the adhered material (part of the adhered material remains on the scraper 205, and part of it falls to the position between the discharge part 4, the scraper 205 and the arc gate 15 when the arc gate 15 continues to rotate upward. When the arc gate 15 returns to its initial position, part of the adhered material falls to the ground, and part of it remains on the upper surface of the arc gate 15 leaking out, and will not enter the inner surface of the arc gate 15). When the scraper 205 needs to be cleaned, the scraper 205 is taken out along the T-slot 204 and then cleaned. When the upper surface of the arc gate 15 leaking out needs to be cleaned, use tools to scrape off the adhered material.

[0024] Working principle: When the arc gate 15 is actually used to control the material discharge, the motor 11 is started to drive the rotating rod 10 to rotate, the rotating rod 10 rotates to drive the worm 8 to rotate, the worm 8 rotates to drive the gear 7 to rotate, the gear 7 rotates to drive the connecting rod 12 to rotate, the connecting rod 12 rotates to drive the rotating plate 16 to rotate, the rotating plate 16 rotates to drive the connecting plate 14 to rotate, the connecting plate 14 rotates to drive the arc gate 15 to rotate, when the arc gate 15 rotates to the appropriate position (the arc gate 15 can be fully opened or partially opened to control the speed of material falling), thereby The limit on the silo is released, and the material falls. When the arc door 15 needs to be turned in the opposite direction, the motor 11 is started to reverse and drive the arc door 15 to rotate in the opposite direction to discharge the material. When the arc door 15 rotates, the cleaning component 2 scrapes and cleans the material adhered to the inner surface of the arc door 15. Through the coordinated use of the motor 11, the rotating rod 10, and the worm 8, the bidirectional rotation of the arc door 15 of the single-door silo is realized, preventing the arc door 15 from being severely worn on one side, thereby maintaining the same degree of wear on the upper surface of the arc door 15, thereby increasing the service life of the arc door 15 and reducing the replacement frequency;

[0025] The specific working mode of the cleaning component 2 is that when the arc gate 15 rotates, the inner surface contacts the scraper 205 (when the cleaning component 2 is set, the scraper 205 can clean half of the area of ​​the arc gate 15, and two sets of scrapers 205 can realize the cleaning of the arc gate 15), and the scraper 205 scrapes off the adhered materials (part of the adhered materials remains on the scraper 205, and part of it falls to the position between the discharge part 4, the scraper 205 and the arc gate 15 when the arc gate 15 continues to rotate upward. When the arc gate 15 returns to its initial position, part of the adhered materials falls to the ground. Part of it remains on the upper surface of the arc door 15 leaking out to the outside and will not enter the inner surface of the arc door 15). When the scraper 205 needs to be cleaned, the scraper 205 is taken out along the T-shaped slot 204 and then cleaned. When the upper surface of the arc door 15 leaking out to the outside needs to be cleaned, a tool is used to scrape off the adhered material. Through the setting of the cleaning component 2, the arc door 15 can be cleaned during rotation to prevent the adhered material from affecting the smoothness of the discharge, thereby ensuring normal discharge. In addition, the movable scraper 205 is convenient for cleaning and maintains the cleaning effect.
