[0017] With the adjustment structure, the grating plate is slidably connected inside the first sliding shaft and the second sliding shaft, while the limiting grooves are evenly distributed on one side of the main body. This makes it easy for the protrusions at the top of the grating plate to be placed inside the limiting grooves at different positions. The positioning plate is rotated to one side of the main body and positioned by the fastening bolts, so that the position of the grating plate is fixed, thereby achieving the purpose of convenient and quick adjustment of the spacing of the grating plate.

[0018] By incorporating a cleaning structure, starting the cleaning motor causes the output shaft to drive the transmission belt to rotate inside the main body. Scrapers are evenly installed between the transmission belts, with one side of the scraper contacting the other side of the grating plate. This facilitates scraping and cleaning of the debris accumulated on one side of the grating plate, which is then discharged through the guide plate, thereby improving the efficiency of the grating machine.

[0025] 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.

[0026] Please see Figures 1-5 The present invention provides a bar screen adjustment component for a bar screen machine, comprising a main body 1 and a slide 2.

[0027] Reference Figures 1-4 As shown, a sliding groove 2 is evenly provided on one side of the main body 1. An adjustment structure 3 is provided inside the sliding groove 2. The adjustment structure 3 includes a first sliding shaft 301 provided on one side of the main body 1. A grid plate 302 is evenly provided on the outer wall of the first sliding shaft 301. A protrusion 303 is fixed on one side of the top of the grid plate 302. A second sliding shaft 304 passes through the top of the grid plate 302. A limiting groove 305 is evenly provided on the outer wall of the main body 1 on one side of the second sliding shaft 304. A positioning plate 306 is hinged to the outer wall of the main body 1 above the limiting groove 305. Both sides of the positioning plate 306 are... The grating plates 302 are evenly distributed on the outer wall of the first sliding shaft 301 and are slidably connected on the outer wall of the first sliding shaft 301. The second sliding shaft 304 and the first sliding shaft 301 are slidably connected inside the sliding groove 2. The limiting grooves 305 are evenly distributed on the outer wall of the main body 1. The protrusions 303 are set inside the limiting grooves 305. The protrusions 303 and the main body 1 form a locking structure through the limiting grooves 305. The fastening bolts 307 extend into the interior of the main body 1 and are threadedly connected to the main body 1.

[0028] In the process of cleaning gravel and debris carried in sewage using a bar screen, the distance between the bar screen plates 302 needs to be adjusted according to the size of the gravel and debris that may be carried inside. An adjustment structure 3 is provided, allowing the positioning plate 306 to be positioned by a threaded connection between the positioning bolt 307 and the main body 1. This position prevents the protrusion 303 inside the limiting groove 305 from sliding out. Opening the positioning plate 306 facilitates the pulling of the sliding shaft outward from the sliding groove 2, moving the protrusion 303 away from the limiting groove 305. This allows the bar screen plates 302 to slide on the outer wall of the sliding shaft, placing the protrusion 303 at different positions in the limiting groove 305. This facilitates the adjustment of the distance between multiple sets of bar screen plates 302, greatly increasing the practicality of the device.

[0029] Reference Figure 1 , Figure 2 and Figure 5 As shown, cleaning structures 4 are installed on both sides of the main body 1. The cleaning structure 4 includes cleaning motors 401 installed on both sides of the main body 1. Each side of the cleaning motor 401 is provided with an output shaft 402. A transmission belt 403 is installed on the outer wall of the output shaft 402. A scraper 404 is installed on the inner wall of the transmission belt 403. A guide plate 405 is installed on the outer wall of the main body 1 on one side of the scraper 404. The scrapers 404 are evenly distributed on one side of the transmission belt 403. One side of the scraper 404 abuts against one side of the grid plate 302.

[0030] To prevent debris from accumulating on one side of the grating plate 302 after it has been blocked, which could affect the effectiveness of the grating machine, a cleaning structure 4 is provided. This allows the cleaning motor 401 to be started, which drives the output shaft 402 to rotate, causing the transmission belt 403 on its outer wall to rotate. Scrapers 404 are evenly installed between the two sets of transmission belts 403, which allows the scrapers 404 to scrape and clean the debris accumulated on one side of the grating plate 302. When the scraper 404 rotates to the top of the transmission belt 403, the debris slides down the top of the scraper 404 under its own weight, and the guide plate 405 guides the debris, thus greatly increasing the practicality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
