[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] Please see Figures 1-4 In one embodiment of this utility model, a dredging and filtration device for river water conservancy construction is provided, including a mixing component 1, a feeding rack 2 is provided on one side of the mixing component 1, a screening component 3 is provided inside the feeding rack 2 for blocking stones stirred up by the mixing component 1, the screening component 3 is drivenly connected to the mixing component 1, a sweeping component 4 is provided on the screening component 3 for cleaning the screening component 3, the sweeping component 4 is drivenly connected to the mixing component 1, the feeding rack 2 is connected to the suction pipe 5, and a suction pump 6 is provided above the suction pipe 5.
[0020] The coordinated operation of the mixing component 1, the screening component 3, and the sweeping component 4 enables efficient and smooth river dredging operations. The mixing component 1 agitates the silt at the bottom of the river to form a mud-water mixture, facilitating the dredging operation; the screening component 3 effectively intercepts larger particles such as stones stirred up during the mixing process, preventing blockage of the dredging system; and the sweeping component 4 cleans the screening component in a timely manner, avoiding screen blockage and ensuring the continuity and efficiency of the dredging operation.
[0021] In another embodiment of the present invention, the mixing assembly 1 includes a support plate 7 fixedly connected to one side of the feed rack 2, a drive motor 8 fixedly connected to the support plate 7, a stirring shaft 9 rotatably connected to the drive motor 8, a plurality of fixed rollers 10 fixedly connected to the stirring shaft 9, and a stirring paddle 11 provided on the fixed rollers 10.
[0022] In this embodiment of the invention, a drive motor 8 drives a stirring shaft 9 to rotate. Multiple sets of fixed rollers 10 are fixedly connected to the stirring shaft 9, and a stirring paddle 11 is provided on the fixed rollers 10. When the stirring shaft 9 rotates, it drives the fixed rollers 10 and the stirring paddle 11 to rotate. The stirring paddle 11 stirs the silt at the bottom of the river, so that the silt and water are fully mixed to form a mud-water mixture, which facilitates the subsequent silt suction operation.
[0023] In another embodiment of this utility model, a transmission rod 12 is connected to the stirring shaft 9 via a bevel gear transmission. The transmission rod 12 is rotatably connected to the feed rack 2, and a rotating worm gear 13 is coaxially connected to the transmission rod 12.
[0024] In another embodiment of the present invention, the sieve assembly 3 includes a driven worm wheel 14 that meshes with the rotating worm 13, a positioning rotating rod 15 fixedly connected to the driven worm wheel 14, a reversing gear 16 fixedly connected to the positioning rotating rod 15, the reversing gear 16 meshing with a driven rotating gear ring 17, a rotating filter screen 18 fixedly connected to the driven rotating gear ring 17, and a sliding ring 19 fixedly connected below the rotating filter screen 18.
[0025] In this embodiment of the invention, a positioning rotating rod 15 is fixedly connected to the driven worm gear 14, and a rotating gear 16 is fixedly connected to the positioning rotating rod 15. The rotating gear 16 meshes with a driven rotating gear ring 17, and a rotating filter screen 18 is fixedly connected to the driven rotating gear ring 17. When the driven worm gear 14 rotates, the positioning rotating rod 15 and the rotating gear 16 drive the driven rotating gear ring 17 to rotate, thereby causing the rotating filter screen 18 to rotate. The rotation of the rotating filter screen 18 can effectively intercept larger particles such as stones stirred up during the mixing process, preventing them from entering the suction system and causing blockage.
[0026] In another embodiment of this utility model, the cleaning component 4 includes a rotating disk 20 rotatably connected to the feed rack 2, the rotating disk 20 being rotatably connected to the sliding ring 19, an array of fixing plates 21 being fixedly connected to the rotating disk 20, a cleaning brush 22 being provided on the fixing plates 21, a driven rotating rod 23 being fixedly connected to the rotating disk 20, the driven rotating rod 23 being connected to the transmission rod 12 via a bevel gear, and a pulverizing rotating blade 24 being fixedly connected to the driven rotating rod 23.
[0027] In this embodiment of the invention, an array of fixing plates 21 are fixedly connected to the rotating disk 20, and cleaning brushes 22 are provided on the fixing plates 21. When the rotating disk 20 rotates, it drives the fixing plates 21 and the cleaning brushes 22 to rotate. The cleaning brushes 22 clean the rotating filter screen 18, remove impurities such as stones intercepted on the screen surface, prevent the screen from clogging, and ensure the normal operation of the filter assembly.
[0028] The working principle of this utility model is as follows:
[0029] First, the drive motor 8 drives the agitator shaft 9 to rotate, causing the fixed roller 10 and the agitator paddle 11 on it to rotate accordingly, stirring the riverbed silt and water to form a mud-water mixture, which facilitates silt suction. The worm gear 14 drives the rotating gear ring 17 to rotate via the positioning rod 15 and the adjusting gear 16, which in turn causes the rotating screen 18 to rotate, intercepting large particles of impurities during the mixing process and preventing blockage of the silt suction system. The rotating disk 20 drives the fixed plate 21 and the cleaning brush 22 to rotate, and the cleaning brush 22 cleans impurities from the surface of the rotating screen 18, preventing screen blockage and ensuring the normal operation of the filter assembly.
