Then the dried sand and gravel can be poured downward into the screening box for filtration and screening, thereby obtaining suitable sand and gravel. In the process of using the above-mentioned screening device, it is impossible to stir and disperse the raw materials on the surface of the screening plate, resulting in incomplete screening of sand and gravel raw materials, and it is also impossible to shake the screening plate for screening, which reduces its practicality. Therefore, we propose a civil engineering sand and gravel filtration and screening device. Utility Model Content

Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0020] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0021] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0023] Please see Figure 1-3 This utility model provides a sand and gravel filtration and screening device for civil engineering, including a processing table 1. Symmetrically distributed support seats 3 are fixed to the outer walls of both sides of the processing table 1. A processing channel 2 is vertically formed on the upper surface of the processing table 1. A screening plate 5 is slidably connected between the inner walls of the processing channel 2. Filter holes 6 are formed on the upper surface of the screening plate 5 along a rectangular array direction. An adjusting shaft 7 is rotatably connected to the upper surface of the screening plate 5. Symmetrically distributed dispersing plates 8 are fixed to the outer wall of the adjusting shaft 7. The dispersing plates 8 are perpendicularly arranged to the adjusting shaft 7. A driven shaft 9 is fixed to the upper surface of the adjusting shaft 7. The wall is provided with a connecting thread 14. A connecting plate 10 is fixed on the upper surface of the processing table 1. A connecting plate 21 is fixed at the top of the connecting plate 10. The connecting plate 10 and the connecting plate 21 are arranged perpendicularly. A guide plate 12 is fixed at the other end of the connecting plate 21. A threaded groove is provided on the lower surface of the guide plate 12. One end of the driven shaft 9 extends into the threaded groove. The driven shaft 9 and the guide plate 12 are connected by a threaded transmission, which can automatically drive the adjusting shaft 7 to rotate. This causes the adjusting shaft 7 to drive the dispersing plate 8 to rotate, thus dispersing the material on the surface of the screening plate 5.

[0024] A fixing seat 18 is installed below the screening plate 5 and fixed to the inner wall of the processing channel 2. A fixing spring 19 is fixed between the fixing seat 18 and the screening plate 5. An arc plate 15 is fixed to the lower surface of the screening plate 5 and is vertically arranged between the arc plate 15 and the screening plate 5. A drive motor 16 is fixed to one side of the outer wall of the processing table 1. The output shaft of the drive motor 16 extends into the processing channel 2 and a cam 17 is fixed therein. The cam 17 is located directly below the arc plate 15. The cam 17 can squeeze the arc plate 15, causing the arc plate 15 to drive the screening plate 5 to move up and down in a circular motion. This causes the adjusting shaft 7 to drive the dispersing plate 8 to rotate, effectively performing filtration and screening. A collection box 4 is set below the processing channel 2 for collecting the filtered material. A discharge port 20 is opened on one side of the outer wall of the processing table 1. The discharge port 20 is connected to the inside of the processing channel 2. A baffle 13 is rotatably connected to one side wall of the discharge port 20 to close the discharge port 20, effectively performing filtration and screening.

[0025] This solution includes the following working process: Raw materials are poured into the processing channel 2, causing them to fall onto the surface of the screening plate 5. Then, the drive motor 16 is started, causing the cam 17 to rotate. The cam 17 presses against the arc-shaped plate 15, which in turn moves the screening plate 5. When the cam 17 is not pressing against the arc-shaped plate 15, the screening plate 5 moves downwards under the elastic force of the fixed spring 19, resulting in a reciprocating up-and-down cyclic movement. The screening plate 5 also drives the adjusting shaft 7 to move up and down in a cyclical manner. The adjusting shaft 7 drives the driven shaft 9 to move up and down in a circular motion. The driven shaft 9 rotates through a threaded drive, which in turn drives the adjusting shaft 7 to rotate. The adjusting shaft 7 then drives the dispersing plate 8 to rotate, causing the dispersing plate 8 to stir and screen the material on the surface of the screening plate 5. The screened material falls into the collection box 4 for collection. When cleaning the material on the surface of the screening plate 5, the baffle 13 is opened to discharge the material from the discharge port 20, thus completing the raw material feeding process and the sand and gravel filtration and screening process.
