DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0027] Example 1

[0028] like Figure 1 to Figure 5As shown, this embodiment proposes a silting device for water conservancy project construction, including a base 1, the bottom of the base 1 is fixedly connected with four symmetrically arranged universal wheels 3 by bolts, the top of the base 1 is welded with a handrail 2, the top of the base 1 is fixedly connected with two symmetrically arranged side panels 4 by bolts, the tops of the two side panels 4 are commonly connected with a top plate 6, a motor 7 is installed on the top of the top plate 6, the output end of the motor 7 is fixedly connected with a coaxially arranged second gear 20 through a coupling, the bottom of the top plate 6 is fixedly connected with a box body 8 by screws, the inside of the box body 8 is rotatably installed with a first gear 19, the inside of the box body 8 is threadedly connected with a screw rod 22, the top end of the screw rod 22 is fixedly sleeved with a third gear 21, the third gear 21 and the second gear 20 are meshed with the first gear 19, a reamer 18 is welded to the bottom of the screw rod 22, and a pipe is slidably assembled inside the reamer 18 and the screw rod 22. One side of the two side panels 4 is fixedly connected to the fixing plate 5 by screws, and the bottom of the box body 8 is fixedly connected to the top of the fixing plate 5 by screws. The top of the base 1 is fixedly connected to the filter barrel 10. Through the arrangement of the motor 7 and the reamer 18 and other structures, the output end of the motor 7 drives the second gear 20 to rotate through the coupling, and the third gear 21 also rotates therewith, so that the screw rod 22 rotates therewith, so that the reamer 18 rotates while descending, and some hard lumps of sludge are crushed and then sucked up, making it more convenient to suck up the sludge and improving work efficiency.

[0029] like Figure 4 As shown, a threaded hole is provided at the bottom of the box body 8, and the screw rod 22 is threadedly connected inside the threaded hole. A through hole is provided inside the fixing plate 5, and the screw rod 22 passes through the inside of the through hole.

[0030] like Figure 1 As shown, a box door 9 is rotatably mounted on one side of the box body 8, and a handle is fixedly connected to one side of the box door 9 by screws.

[0031] like Figure 3 As shown, a circular hole 16 is opened inside the base 1 , and the screw rod 22 and the reamer 18 both pass through the circular hole 16 . A square hole 17 is opened inside the base 1 .

[0032] In this embodiment, the entire dredging device is moved to the place where the river needs to be dredged, and then the sludge suction pump is turned on. The output end of the sludge suction pump absorbs the sludge through the hose 23, and then stores it in the filter barrel 10. When encountering some harder sludge blocks, the power supply of the motor 7 can be turned on. The output end of the motor 7 drives the second gear 20 to rotate through the coupling, and the first gear 19 rotates accordingly. The second gear 20 drives the third gear 21 to rotate, thereby causing the screw rod 22 to rotate. Since part of the screw rod 22 is threadedly connected to the inside of the box body 8, the screw rod 22 moves downward while rotating, thereby breaking up large pieces of sludge and driving the pipeline to absorb the sludge, thereby making dredging more convenient and improving work efficiency.

[0033] Example 2

Through the arrangement of structures such as the filter frame 13 and the block 14, the interior of the filter barrel 10 is provided with a filter frame 13, so that it can filter the extracted sludge and discharge the water in the sludge, so that the water will not be moved away when the sludge is transported, and two blocks 14 are provided on the filter frame 13 and are slidably connected to the interior of the filter frame 13, so that the filter frame 13 is easier to disassemble and clean.

[0035] like Figure 2 As shown, two symmetrically arranged chutes are provided inside the filter barrel 10, and two symmetrically arranged stoppers 14 are welded on the filter frame 13. The two stoppers 14 are slidably connected inside the two chutes respectively.

[0037] like Figure 1 As shown, a through hole is opened on one side of the box body 8, and the hose 23 passes through the inside of the through hole. A circular groove is opened on the top of the box body 8, and the output end of the motor 7 passes through the circular groove.

[0038] In this embodiment, when working, the sludge absorbed by the sludge suction pump will fall into the interior of the filter barrel 10, and the water will be filtered out through the filter frame 13, and then the excess water will be discharged from the drain outlet, so that when the sludge is transported, the water will not be transported away together, and blocks 14 are provided on both sides of the filter frame 13, so that the entire filter frame 13 can slide movably inside the filter barrel 10, making disassembly and cleaning more convenient, and two protrusions 24 are provided on the pipeline, and an annular groove is opened inside the screw rod 22. The two protrusions 24 are slidably assembled inside the annular groove, so that when the screw rod 22 moves downward, the pipeline can move downward with it through the protrusions 24, but will not rotate with it, preventing the hose 23 from being broken when the screw rod 22 rotates.
