Technical Field

[0003] The authorized publication number "CN221193504U" discloses a dredging device for water conservancy projects, which records: "The two moving mechanisms are driven by a bidirectional driving mechanism to move closer to or away from each other, and the distance between the two moving mechanisms is adjusted to facilitate the substrate to be erected on the top of the trench, so as to be applicable to trenches of different widths. Then, the lifting mechanism drives the support plate to move downward until the spray dredging mechanism is immersed below the liquid level of the trench, and the spray dredging mechanism sucks the water in the trench and flushes and cleans the silt deposited at the bottom of the trench."

The tops of the driving right-angle rods 23 extend above the third moving plate 18.

[0046] The sludge treatment component 3 further includes a second double-head motor 24, a rotating rod 25, a fixed right-angle plate 26, a third threaded rod 27 and a bevel gear set 28. A second double-head motor 24 is fixedly connected to the side of the top of the third moving plate 18 away from the supporting plate 1. The output ends of both ends of the second double-head motor 24 are fixedly connected to rotating rods 25. Fixed right-angle plates 26 are fixedly connected to both ends of the top of the third moving plate 18 away from the supporting plate 1. A third threaded rod 27 is rotatably connected to the inner side of the fixed right-angle plate 26. The tops of the third threaded rods 27 are threadedly connected to the driving right-angle rods 23. The bottoms of the third threaded rods 27 located in the fixed right-angle plates 26 correspond to the ends of the rotating rods 25 away from the second double-head motor 24. Bevel gear sets 28 are arranged at the ends of the rotating rods 25 away from the second double-head motor 24. The rotating rods 25 drive the third threaded rods 27 to rotate through the bevel gear sets 28.

[0047] The sludge treatment assembly 3 further includes a suction box 29, a connecting plate 30, a movable scraper 31, a fixed rod 35, a second fixing piece 33 and a first spring 34.

[0048] Specifically: By starting the single-head motor 16, the second threaded rod 17 can be driven to rotate inside the second movable groove, so as to drive the third moving plate 18 threadedly connected to the second threaded rod 17 to move horizontally inside the second movable groove, thereby expanding the pumping range of the suction box 29 at the bottom of the second hose 21;

[0049] By starting the second double-head motor 24, the rotating rod 25 can be driven to rotate. At the same time, through the setting of the bevel gear set 28, the third threaded rod 27 can be driven to rotate synchronously inside the fixed right-angle plate 26, so as to drive the driving right-angle rod 23 threadedly connected to the top of the third threaded rod 27 to move upward or downward outside the third threaded rod 27, thereby driving the bottom driving plate 22 to move synchronously through the movement of the two driving right-angle rods 23. And through the connection setting of the connecting plate 30, the position of the suction box 29 at the bottom of the groove can be adjusted while the driving plate 22 moves, thereby further improving the convenience of the suction box 29 for cleaning the sludge at the bottom of the groove;

[0050] After the suction box 29 drives the movable scraper 31 to contact the bottom of the groove, through the movement of the universal wheels 10, the suction box 29 can be driven to move synchronously inside the groove. At the same time, through the setting of the movable scraper 31, the sludge at the bottom of the groove can be scraped up, and the sludge that has not been pumped away for the first time can be separated from the inside of the groove, so as to facilitate the second cleaning operation of the sludge inside the groove;

[0051] Through the rotational connection setting of the movable scraper 31, the movable scraper 31 can contact harder objects such as stones during the movement process, and can adaptively adjust the angle of the movable scraper 31. At the same time, through the setting of the first spring 34, the movable scraper 31 can be kept in a downward pressing state, so as to keep the effect of scraping the silt on the inner side of the trench;

[0052] By turning on the water pump 19, the water and silt on the inner side of the trench can be pumped through the setting of the second hose 21, and through the setting of the first hose 20, the water and silt are pumped into the concentration box 12. Then, by turning on the electric push rod 14, the extrusion plate 15 is driven to move downward, so as to be able to extrude the silt and water in the concentration box 12. During the extrusion process, the water in the silt will flow out through the filter plate 13, so as to compact the relatively dry silt, which is convenient for subsequent cleaning of the dry silt.

[0053] Embodiment 3:

[0054] This Embodiment 3 further discloses the specific structure of the limiting component 4 on the premise of the above embodiment. By cooperating the limiting component 4 with the structure in the above embodiment, the effect of limiting the filter plate 13 can be achieved, thereby improving the convenience of cleaning the silt placed centrally.

[0055] A novel water conservancy project dredging device provided in Embodiment 1 and Embodiment 2 is further optimized. Specifically, as Figure 9 - Figure 10 shown, the limiting component 4 includes a fixed rod 35, a right-angle limiting piece 36, a fixed hollow block 37, a movable right-angle plate 38 and a second spring 39. At the top of both ends of the concentration box 12 close to the filter plate 13, fixed rods 35 are fixedly connected. Right-angle limiting pieces 36 are rotatably connected to the outer sides of the fixed rods 35. The tops of the right-angle limiting pieces 36 are in a limiting fit with the filter plate 13. Fourth movable grooves are opened on one side of the bottoms of the right-angle limiting pieces 36 close to the filter plate 13. Fixed hollow blocks 37 are fixedly connected to both ends of the concentration box 12 close to the filter plate 13, and the positions of the fixed hollow blocks 37 correspond to the fourth movable grooves. The tops and bottoms of the inner sides of the fixed hollow blocks 37 are in clearance fit with the movable right-angle plates 38, and the tops and bottoms of the two movable right-angle plates 38 penetrate through the tops and bottoms of the fixed hollow blocks 37 and are in a plug-in limiting fit with the inner sides of the fourth movable grooves. Fifth movable grooves are opened on the side walls of the fixed hollow blocks 37 far from the concentration box 12. The sides of the movable right-angle plates 38 far from the concentration box 12 penetrate through the fifth movable grooves and are in a clearance fit with the fifth movable grooves. Second springs 39 are arranged between the two movable right-angle plates 38, and the tops and bottoms of the second springs 39 are fixedly connected to the two movable right-angle plates 38.

[0056] Specifically: By setting the second spring 39, the two movable right-angle plates 38 can be pushed out respectively towards the top and bottom of the fixed hollow block 37 inside the fixed hollow block 37. After the movable right-angle plates 38 are pushed out, a plug-in limit fit can be carried out on the inner side of the fourth movable groove, so as to further stabilize the limit effect of the top of the right-angle limit piece 36 on the filter plate 13;

[0057] When there is a lot of dry silt inside the central box 12, by making the two movable right-angle plates 38 approach each other, the plug-in limit effect of the two movable right-angle plates 38 on the fourth movable groove can be cancelled, so that the right-angle limit piece 36 can be flipped, and the top of the right-angle limit piece 36 cancels the limit effect on the filter plate 13, so that the central box 12 can be opened by flipping the filter plate 13, facilitating the staff to clean the silt inside the central box 12;

[0058] After cleaning, the filter plate 13 can be flipped to make the side wall of the central box 12 in a closed state, and then the right-angle limit piece 36 is rotated so that the fourth movable groove at the bottom of the right-angle limit piece 36 wraps the outside of the fixed hollow block 37. At this time, the top of the right-angle limit piece 36 will have a limit effect on the filter plate 13. At the same time, due to the elastic setting of the second spring 39, the two movable right-angle plates 38 inside the fixed hollow block 37 can once again have a plug-in limit effect on the fourth movable groove, so as to further stabilize the limit effect of the right-angle limit piece 36 on the filter plate 13.
