Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a sediment screening device for concrete processing, including a processing box 1, the top surface of the processing box 1 is provided with two symmetrically distributed feed ports, two feed hoppers 2 are fixed on the top surface of the processing box 1 corresponding to the feed ports, mounting plates 12 are fixed on both sides of the inner wall of the processing box 1, movable rods 11 are movably penetrated through the top surfaces of the two mounting plates 12, a top plate 10 is fixed to the top of the movable rod 11, the inner top wall of the processing box 1 and the top plate 10 cooperate with each other, a bracket 5 is fixed on one side of the processing box 1, a driving motor 6 is fixedly installed on the top surface of the bracket 5, and the driving motor A first gear 7 is fixed to the output end of 6, and two rotating shafts 13 are rotatably connected to one side of the inner wall of the processing box 1. A second gear 8 is fixed to one end of the two rotating shafts 13, and the two second gears 8 are respectively engaged with the first gear 7 for transmission. A turntable 17 is fixed to the other end of the two rotating shafts 13, and a rotating block 16 is fixed to the surface of the turntable 17. A rectangular ring 18 is fixed to the bottom end of the movable rod 11, and the rectangular ring 18 is movably sleeved on the outer surface of the rotating block 16. A sieve plate 15 is rotatably connected to one side of the inner wall of the processing box 1, and a blanking plate 22 is rotatably connected to one side of the processing box 1 corresponding to the sieve plate 15.

[0021] Further as Figure 2 and Figure 3As shown, it is worth explaining in detail that a connecting block 19 is fixed to the bottom surface of one of the rectangular rings 18, a first connecting rope 20 is fixed to the surface of the connecting block 19, and the bottom end of the first connecting rope 20 is fixed to the top surface of the sieve plate 15, wherein a second connecting rope 21 is fixed to the bottom surface of the other rectangular ring 18, and the end of the second connecting rope 21 movably passes through the sieve plate 15 and is fixed to the top surface of the blanking plate 22.

[0022] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that a first discharge pipe 3 matched with the sieve plate 15 is fixed to one side of the processing box 1, and a second discharge pipe 4 matched with the discharge plate 22 is fixed to the side of the processing box 1 away from the first discharge pipe 3.

[0023] This scheme has the following working process: the silt is easy to clump when stored for a long time or is damp. At this time, the construction workers need to shovel the clumped silt and then screen it. This will reduce the efficiency of silt screening and increase the work intensity of the construction workers. The silt is poured from the feed hopper 2 into the processing box 1, and then the drive motor 6 is started. The drive motor 6 drives the first gear 7 to rotate, thereby driving the two second gears 8 to rotate. The second gear 8 drives the rotating shaft 13 to rotate in the processing box 1, and the rotating shaft 13 drives the turntable 17 to rotate, thereby driving the rotating block 16 to make a circular motion. The rectangular ring 18 is limited by the movable rod 11, so that the rotating block 16 drives the rectangular ring 18 to move up and down reciprocatingly. The movable rod 11 pushes the top plate 10 to move up and down, so that the top plate 10 squeezes and crushes the agglomerated mud and sand, and the crushed mud and sand fall onto the screen plate 15, and the mud and sand are screened by the screen plate 15. The filtered mud and sand fall onto the discharge plate 22 and are discharged from the second discharge pipe 4, while the debris in the mud and sand moves down along the screen plate 15 and is discharged from the first discharge pipe 3. One of the rectangular rings 18 pulls the first connecting rope 20 when moving up and down, thereby pulling the screen plate 15 to shake to a certain extent, which is beneficial to the screening of mud and sand, and the other rectangular ring 18 pulls the second connecting rope 21 to move up and down, thereby driving the discharge plate 22 to shake, thereby improving the discharge efficiency of the discharge plate 22.

[0024] According to the above working process, it can be known that: by setting the structures such as the driving motor 6, the first gear 7, the second gear 8, the rotating shaft 13, the rectangular ring 18, the movable rod 11 and the top plate 10, the top plate 10 can squeeze and crush the silt agglomerated in the feed, thereby improving the screening efficiency of the silt and reducing the work intensity of the construction personnel. The silt is screened by the sieve plate 15, and the silt and debris are discharged from the first discharge pipe 3 and the second discharge pipe 4 respectively, which brings convenience to the construction personnel. One of the rectangular rings 18 pulls the first connecting rope 20 when moving up and down, thereby pulling the sieve plate 15 to shake to a certain extent, which is beneficial to the screening of the silt. The other rectangular ring 18 pulls the second connecting rope 21 to move up and down, thereby driving the unloading plate 22 to shake, thereby improving the unloading efficiency of the unloading plate 22.

[0025] Further as Figure 3 As shown, it is worth explaining in detail that a fixing frame 23 is fixed to the inner wall of the processing box 1, and a transmission roller 24 is rotatably connected to the inner side of the fixing frame 23. The first connecting rope 20 is in contact with the outer surface of the transmission roller 24. When the first connecting rope 20 is pulled, the transmission roller 24 is driven to rotate on the fixing frame 23, thereby guiding the first connecting rope 20.

[0026] Further as Figure 2 As shown, it is worth explaining in detail that the top surface of the mounting plate 12 movably passes through the limit rod 14, and the top end of the limit rod 14 is fixed to the bottom surface of the top plate 10. When the top plate 10 moves, it drives the limit rod 14 to slide on the mounting plate 12, thereby improving the stability of the top plate 10 when it is flapped.

[0027] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that four supporting legs distributed in a rectangular shape are fixed to the bottom surface of the processing box 1, and the top plate 10 is inclined. The inclined top plate 10 is better coordinated with the inner top wall of the processing box 1 to better perform the material shooting work; an arc-shaped guard plate 9 is fixed on one side of the processing box 1 corresponding to the first gear 7 and the second gear 8, and the arc-shaped guard plate 9 protects the first gear 7 and the second gear 8.
