[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] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is an adjustable scraper conveyor, comprising: Scraper conveyor 101; The filter hole quick adjustment assembly includes a slot 201, a first filter plate 202, a second filter plate 203, a receiving rod 204, a threaded groove 205, and a wing screw 206. The slot 201 is opened on the feed hopper of the scraper conveyor 101. The first filter plate 202 and the second filter plate 203 are movably inserted in the slot 201. The receiving rod 204 is fixedly connected to one side of the feed hopper of the scraper conveyor 101. The threaded groove 205 is opened through the receiving rod 204, and the wing screw 206 is movably connected in the threaded groove 205. The scraper conveyor 101 is a model of the MGB series. It adopts a closed trough, in which the material is "buried" and conveyed by the scraper chain. It has good sealing performance and no dust spillage, making it suitable for powdery and granular materials. The slot 201 ensures the movable connection between the first filter plate 202 and the second filter plate 203. When the first filter plate 202 slides on the second filter plate 203, the diameter of the new filter hole formed by the overlap of the filter holes will change accordingly, thereby realizing the adjustment of the new filter hole diameter. The receiving rod 204 ensures the opening of the threaded groove 205. When the wing screw 206 rotates in the threaded groove 205, it can move away from and tighten its contact with the first filter plate 202, thereby realizing the quick and convenient adjustment of the new filter hole diameter.

[0018] The lengths of the first filter plate 202 and the second filter plate 203 are both greater than the width of the feed hopper of the scraper conveyor 101; The dimensional arrangement of the above-mentioned components ensures a stable connection between the first filter plate 202 and the second filter plate 203.

[0019] The mesh diameters of the first filter plate 202 and the second filter plate 203 are the same. The dimensional arrangement of the above components ensures that the filter holes can smoothly screen the material when the first filter plate 202 and the second filter plate 203 overlap.

[0020] Working principle: The operator manually rotates the wing screw 206 counterclockwise. Since the wing screw 206 is threaded into the threaded groove 205, with rotation, the wing screw 206 gradually moves outward along the threaded groove 205, its end separating from the side of the first filter plate 202, releasing the restriction on the first filter plate 202, allowing the first filter plate 202 to slide within the slot 201. Depending on the particle size of the material to be screened, the operator manually pushes the first filter plate 202 to slide relative to the second filter plate 203 within the slot 201. Because the mesh diameters of the first filter plate 202 and the second filter plate 203 are the same, the overlapping area of ​​the mesh changes during sliding, and the diameter of the new filter hole formed by the overlapping part also changes accordingly. For example, when screening materials with smaller particle sizes... The first filter plate 202 is pushed to reduce the overlapping area of ​​the meshes of the two filters, resulting in a smaller new filter hole diameter. When it is necessary to screen materials with larger particle sizes, the first filter plate 202 is pushed to increase the overlapping area of ​​the meshes of the two filters, resulting in a larger new filter hole diameter. When the first filter plate 202 slides to a suitable position and the new filter hole diameter meets the material screening requirements, the operator rotates the wing screw 206 clockwise by hand, moving it along the thread groove 205 towards the first filter plate 202 until the end of the wing screw 206 tightly abuts against the side of the first filter plate 202, firmly fixing the first filter plate 202 in the current position to prevent it from sliding during subsequent material conveying, ensuring the filter hole diameter is stable, and completing the rapid filter hole adjustment operation. At this time, the scraper conveyor 101 can feed and convey materials normally.

[0021] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The quick-disassembly and replacement component includes a slot 301, a lever 302, and a limiting plate 303. The second filter plate 203 has a slot 301 on its side, and the lever 302 is movably connected in the slot 301. The limiting plate 303 is fixedly connected to the side of the lever 302. The lever 302 and the limiting plate 303 are movably connected to one side of the feed hopper of the scraper conveyor 101. The side length of the limiting plate 303 is greater than the diameter of the slot 301. The quick-disassembly and replacement component also includes an L-shaped rod 304, a guide rod 305, and a spring 306. One end of the L-shaped rod 304 is fixedly connected to the feed hopper of the scraper conveyor 101. The guide rod 305 is movably connected in the L-shaped rod 304. One end of the guide rod 305 is fixedly connected to the limiting plate 303. The spring 306 is movably sleeved on the outer ring of the guide rod 305. The L-shaped rod 304 provides a guarantee for the movable connection of the guide rod 305. The guide rod 305 provides a guarantee for the movable connection of the spring 306. The spring 306 is located between the L-shaped rod 304 and the limiting plate 303, so that the locking rod 302 can be firmly locked in the locking groove 301, and the second filter plate 203 can be firmly limited in the feed hopper of the scraper conveyor 101.

[0022] The quick-disassembly and replacement components also include a pull plate 307, with the other end of the guide rod 305 fixedly connected to the pull plate 307; The pull plate 307 is designed to allow the user to pull the guide rod 305, and then remove the locking rod 302 from the slot 301 through the limiting plate 303. This enables the quick and convenient disassembly and installation of the second filter plate 203, and facilitates timely replacement when the second filter plate 203 is damaged.

[0023] Working principle: When the second filter plate 203 needs to be replaced, the operator holds the pull plate 307 and pulls it away from the feed hopper of the scraper conveyor 101. The guide rod 305 moves within the L-shaped rod 304, simultaneously driving the limiting plate 303, which is fixed to one end of the guide rod 305, to move synchronously. During the movement of the limiting plate 303, the spring 306, which is sleeved on the outer ring of the guide rod 305, is compressed. The locking rod 302, which is fixed to the limiting plate 303, moves with the limiting plate 303 and gradually pulls out of the slot 301 of the second filter plate 203, releasing the locking and limiting of the second filter plate 203. At this time, the damaged second filter plate 203 is removed, and a new second filter plate 203 is taken. The above steps are then repeated in reverse to complete the replacement.

[0024] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
