Abstract
Description
Technical Field
[0001] This utility model relates to the field of scraper conveyor technology, and more specifically to a conveying structure for a scraper conveyor. Background Technology
[0002] A scraper conveyor is a continuous conveyor that uses the thrust of scrapers on a traction component (usually a chain) to move bulk materials along a trough. Scraper conveyors can transport materials horizontally, inclined, or vertically. During transport, the scraper chain is completely submerged in the material, hence the name "submerged scraper conveyor." Scraper conveyors offer advantages such as simple structure, low cost, multi-point feeding or unloading along their entire length, and flexible operation. However, their disadvantages include high power consumption due to friction between the material, scrapers, and the trough, and the trough's susceptibility to wear.
[0003] However, current scraper conveyors, in order to reduce wear between the scraper and the trough when conveying materials, leave a certain clearance between the scraper and the trough. Under this premise, it can be used normally when conveying large-volume materials. However, when conveying small-volume materials, in order to ensure the conveying effect of the scraper and prevent material leakage from the bottom of the scraper, the scraper needs to be replaced to ensure that the scraper and the trough are in a tight fit. Since there are many scrapers, scraper conveyors have the disadvantages of being cumbersome to operate and having poor applicability when conveying materials of different volumes. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a conveying structure for a scraper conveyor to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a conveying structure for a scraper conveyor, including a conveying pipe, an inlet pipe embedded in the upper left of the conveying pipe, an outlet pipe embedded in the lower right of the conveying pipe, a conveying assembly inside the conveying pipe, the conveying assembly including two rotating shafts rotatably connected to both ends of the inner wall of the conveying pipe, two sprockets fixedly mounted on the surface of each of the two rotating shafts, chains provided on the surface of each of the two sprockets, a plurality of scrapers equidistantly arranged between the two chains, a moving gap reserved between the bottom end of the scraper and the inner bottom wall of the conveying pipe, and an adjusting assembly provided between the bottom end of the conveying pipe and the scraper;
[0006] The adjusting assembly includes an electromagnet fixedly installed at the bottom of the conveying pipe. A telescopic groove is formed on the side of the scraper near the inner wall of the conveying pipe. An extension plate, made of iron, is slidably connected inside the telescopic groove. A tension spring is fixedly installed on the inner wall of the telescopic groove, with the other end of the spring fixed to the surface of the extension plate. When the electromagnet is energized, the extension plate on the bottom surface of the scraper overcomes the tension of the spring and adheres tightly to the inner bottom wall of the conveying pipe.
[0007] Furthermore, two brackets are fixedly installed at the bottom of the conveying pipe, and a support plate is welded to the bottom of the bracket. The surface of the support plate is provided with mounting holes. Bolts are inserted into the mounting holes to firmly fix the support plate to the ground, thereby achieving the effect of stable installation of the conveying pipe.
[0008] Furthermore, a servo motor that drives the rotating shaft to rotate counterclockwise is fixedly installed on the front side of the feeding pipe.
[0009] Furthermore, the inner wall of the conveying pipe is provided with a striking assembly corresponding to the scraper at the upper opening of the discharge pipe. The striking assembly includes a drive motor fixedly installed on the front of the conveying pipe. The output shaft of the drive motor extends into the interior of the conveying pipe and is fixedly mounted with a shaft. A mounting seat is fixedly mounted on the surface of the shaft. A mounting shaft is rotatably connected to the surface of the mounting seat. A striking rod is fixedly mounted on the surface of the mounting shaft. A torsion spring is provided on the surface of the mounting shaft to drive the striking rod to remain perpendicular to the surface of the shaft. One end of the torsion spring is fixed to the inner wall of the mounting seat, and the other end of the torsion spring is fixed to the surface of the mounting shaft. When using this scraper conveyor to convey highly viscous materials, by setting up the striking assembly, during the process of conveying materials using the scraper, the drive motor drives the shaft to rotate, which in turn drives the striking rod to rotate through the mounting seat and the mounting shaft. The striking rod collides with the scraper, vibrating the scraper and preventing materials from adhering to the scraper surface, ensuring normal material discharge. After the striking rod collides with the scraper, it can rotate about the mounting shaft as an axis to avoid the scraper.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] 1. In use, this utility model utilizes a servo motor to drive a rotating shaft, which in turn drives a chain via a sprocket. Material is fed through the inlet pipe, and the chain-driven counter-clockwise rotation of the scraper pushes the material to the outlet pipe, achieving material conveying. When conveying larger volumes of material, the extension plate is retracted into the telescopic groove by a tension spring, preventing the bottom of the extension plate from contacting the inner wall of the conveying pipe, thus reducing wear on the scraper and the conveying pipe, and minimizing power consumption. When conveying smaller volumes of material, the electromagnet is energized, and its magnetic force ensures the extension plate adheres tightly to the inner bottom wall of the conveying pipe, guaranteeing effective conveying. In summary, this utility model has the advantages of strong applicability and simple operation, making it worthy of widespread use.
[0012] 2. In this utility model, when conveying highly viscous materials, a striking component is installed. During the material conveying process using a scraper, a drive motor drives a shaft to rotate, which in turn drives a striking rod to rotate via a mounting base and mounting shaft. The striking rod collides with the scraper, vibrating the scraper and preventing material from adhering to the scraper surface, thus ensuring normal material feeding. After the striking rod collides with the scraper, it can rotate around the mounting shaft as an axis to avoid the scraper. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The conveying structure of the scraper conveyor involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Reference Figure 1-4 This utility model provides a conveying structure for a scraper conveyor, including a conveying pipe 1. Two brackets 12 are fixedly installed at the bottom end of the conveying pipe 1. A support plate 13 is welded to the bottom end of the bracket 12. The surface of the support plate 13 is provided with mounting holes 14.
[0020] By inserting bolts into the mounting holes 14, the support plate 13 can be firmly fixed to the ground, thereby achieving a stable installation of the material conveying pipe 1.
[0021] The feed pipe 2 is installed on the upper left side of the feed pipe 1, and the discharge pipe 3 is installed on the lower right side of the feed pipe 1.
[0022] The inside of the conveying pipe 1 is equipped with a conveying assembly, which includes two rotating shafts 4 rotatably connected to both ends of the inner wall of the conveying pipe 1. A servo motor 15 that drives the rotating shafts 4 to rotate counterclockwise is fixedly installed on the front of the conveying pipe 1.
[0023] Two sprockets 5 are fixedly mounted on the surfaces of the two rotating shafts 4. Chains 6 are provided on the surfaces of the two sprockets 5. Several scrapers 7 are arranged at equal intervals between the two chains 6.
[0024] During the use of this scraper conveyor, the conveyor is connected to an external power control system, and the servo motor 15 is started. The rotation of the servo motor 15 drives the rotating shaft 4 to rotate, which in turn drives the chain 6 and scraper 7 to rotate through the sprocket 5. External materials are fed from the feed pipe 2. Under the action of the chain 6 driving the scraper 7 to rotate counterclockwise, the material at the bottom wall of the feed pipe 1 can be pushed to the discharge pipe 3, thus achieving the purpose of material conveying.
[0025] A moving gap is reserved between the bottom end of the bottom scraper 7 and the inner bottom wall of the conveying pipe 1, and an adjustment component is provided between the bottom end of the conveying pipe 1 and the scraper 7.
[0026] The adjustment assembly includes an electromagnet 8 fixedly installed at the bottom of the feed pipe 1. A telescopic groove 9 is provided on the side of the scraper 7 near the inner wall of the feed pipe 1. An extension plate 10 is slidably connected inside the telescopic groove 9. The extension plate 10 is made of iron. A tension spring 11 is fixedly installed on the inner wall of the telescopic groove 9. The other end of the tension spring 11 is fixed to the surface of the extension plate 10. When the electromagnet 8 is energized, the extension plate 10 on the surface of the bottom scraper 7 overcomes the tension of the tension spring 11 and sticks tightly to the inner bottom wall of the feed pipe 1.
[0027] Furthermore, when using this scraper conveyor to transport larger volume materials, under the action of the tension spring 11, the extension plate 10 can be retracted into the telescopic groove 9, and the bottom end of the extension plate 10 does not contact the inner wall of the conveying pipe 1, reducing wear between the scraper 7 and the conveying pipe 1 and reducing power consumption. When transporting smaller volume materials, the electromagnet 8 is energized, and the magnetic force of the electromagnet 8 is used to make the extension plate 10 fit tightly against the inner bottom wall of the conveying pipe 1, ensuring the conveying effect. In summary, this utility model has the advantages of strong applicability and simple operation when conveying materials of different sizes, and is worth promoting and using.
[0028] The inner wall of the feed pipe 1 is provided with a striking component corresponding to the upper opening of the discharge pipe 3 and the scraper 7. The striking component includes a drive motor 16 fixedly installed on the front side of the feed pipe 1. The output shaft of the drive motor 16 extends into the interior of the feed pipe 1 and is fixedly installed with a shaft 17. A mounting base 18 is fixedly installed on the surface of the shaft 17. A mounting shaft 19 is rotatably connected to the surface of the mounting base 18. A striking rod 20 is fixedly installed on the surface of the mounting shaft 19.
[0029] The surface of the mounting shaft 19 is provided with a torsion spring 21 that drives the striking rod 20 to remain perpendicular to the surface of the shaft 17. One end of the torsion spring 21 is fixed to the inner wall of the mounting base 18, and the other end of the torsion spring 21 is fixed to the surface of the mounting shaft 19.
[0030] Furthermore, when using this scraper conveyor to transport highly viscous materials, by setting up a striking component, during the material conveying process, the drive motor 16 drives the shaft 17 to rotate clockwise, which in turn drives the striking rod 20 to rotate clockwise through the mounting base 18 and mounting shaft 19. The striking rod 20 collides with the scraper 7, vibrating the scraper 7 and preventing material from adhering to the surface of the scraper 7, ensuring normal material discharge. After the striking rod 20 collides with the scraper 7, the striking rod 20 can rotate around the mounting shaft 19 as the axis, avoiding the moving scraper 7 and ensuring the normal operation of the conveying operation.
[0031] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
