[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1and Figure 2 As shown, a dredging device for water conservancy construction includes a movable mobile base 1, a processing box 5 is fixedly installed on the upper left part of the mobile base 1, an anti-accumulation screening component 4 is fixedly installed on the front and rear sides of the processing box 5, a sludge conveying component 2 is fixedly installed on the right part of the processing box 5, and a material collection and maintenance component 3 is fixedly installed on the right part of the mobile base 1.

[0026] The silt conveying component 2 can be used to convey the silt in the riverbed to the processing box 5 for collection and processing. The material collecting and maintenance component 3 can be used to make the silt accumulate in the silt removal bucket 39 when the mobile base 1 moves, and several L-shaped silt removal plates 23 and the electric conveyor belt 22 cooperate to transport the silt to the processing box 5. Secondly, since the silt removal bucket 39 is easy to touch the stones in the riverbed during the movement, the silt removal bucket 39 can be quickly disassembled for maintenance or replacement after the silt removal is completed. The anti-deposition screening component 4 can push the silt entering the processing box 5 back and forth, so that the silt and stones are quickly separated, and at the same time, it can also prevent the silt from accumulating in the collection box 48, thereby improving the practicality of the device.

[0027] like Figure 2 As shown, the sludge conveying assembly 2 includes two mounting plates 21, a feed trough is provided on the right top of the processing box 5, the tops of the opposite sides of the two mounting plates 21 are fixedly mounted to the right parts of the front and rear sides of the processing box 5, an electric conveyor belt 22 is movably connected to the middle parts of the opposite sides of the two mounting plates 21, and a plurality of L-shaped silt removal plates 23 are fixedly mounted on the outer peripheral surface of the electric conveyor belt 22.

[0028] The electric conveyor belt 22 is an existing mechanism, which consists of a driving motor, two driving rollers and a conveyor belt. When the driving motor is started, the conveyor belt drives and transfers the silt in the silt cleaning bucket 39 to the processing box 5 through a plurality of L-shaped silt cleaning plates 23, wherein the plurality of L-shaped silt cleaning plates 23 will pass through the feed trough during movement. The opening of the feed trough can prevent the processing box 5 body from affecting the movement of the L-shaped silt cleaning plates 23, and the screening plate 47 is located below the feed trough.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the material receiving and maintenance component 3 includes a protective cover 31, a storage groove 32 is opened at the front right part of the upper end of the movable base 1, the lower end of the protective cover 31 is fixedly installed at the top position of the left part of the inner wall of the storage groove 32, the inner wall of the protective cover 31 is rotatably connected with a reverse double-threaded rod 33 that passes through the front part of the protective cover 31, a hand wheel 34 is fixedly installed at the front end of the reverse double-threaded rod 33, and the front and rear parts of the outer wall of the reverse double-threaded rod 33 are both threadedly connected with a moving block 35.

[0030] The protective cover 31 can prevent the mud and water dropped during the transmission of the L-shaped silt clearing plate 23 from affecting the rotation of the reverse double-threaded rod 33. The outer wall of the reverse double-threaded rod 33 is coated with waterproof material. The reverse double-threaded rod 33 can be rotated by the hand wheel 34. The two moving blocks 35 are threadedly connected to the reverse double-threaded rod 33 to move closer to or away from each other.

[0031] like Figure 3 and Figure 4 As shown, a slide groove 36 is opened on the left inner wall of the storage groove 32 , and sliders 37 are fixedly installed on the left sides of the two moving blocks 35 , and the left sides of the two sliders 37 are slidably connected to the inner wall of the slide groove 36 .

[0032] When the two moving blocks 35 move, the two sliding blocks 37 slide in the sliding grooves 36 at the same time, and the cooperation between the corresponding sliding blocks 37 and the sliding grooves 36 has a limiting effect on the movement of the two moving blocks 35 .

[0033] like Figure 3 and Figure 4 As shown, T-shaped slide grooves are provided at the front and rear positions of the bottom of the inner wall of the storage groove 32, and the inner walls of the two T-shaped slide grooves are slidably connected with T-shaped slide plates 38. The upper ends of the two T-shaped slide plates 38 are fixedly installed with dredging buckets 39, and the front and rear positions of the upper left end of the dredging bucket 39 are fixedly installed with fixed blocks 311. The two fixed blocks 311 have holes on the sides away from each other, and the opposite sides of the two movable blocks 35 are fixedly installed with plug rods 310, and the outer walls of the two plug rods 310 are movably connected with the inner walls of the two holes on the sides close to each other.

[0034] When the two moving blocks 35 approach each other until the two plug rods 310 are inserted into the corresponding insertion holes, the dredging bucket 39 can be fixed. When the two moving blocks 35 move away from each other until the two plug rods 310 are separated from the corresponding insertion holes, the dredging bucket 39 can be slid out of the two T-shaped slides through the two T-shaped slide plates 38.

[0035] like Figure 5 As shown, the anti-accumulation screening assembly 4 includes a motor 41, the front end of the motor 41 is fixedly mounted on the front top of the processing box 5, the output end of the motor 41 is fixedly sleeved with an incomplete gear 42, the front top of the processing box 5 is slidably connected with an internal rack frame 43, and the outer surface of the incomplete gear 42 is meshed with the upper and lower parts of the inner wall of the internal rack frame 43.

[0036] The incomplete gear 42 can be driven to rotate by the output end of the motor 41 . The inner wall of the inner rack frame 43 is provided with teeth at the upper and lower parts. The inner rack frame 43 slides back and forth by meshing with the incomplete gear 42 .

[0037] like Figure 5As shown, movable grooves are provided at the top of the front and rear sides of the processing box 5, and the inner walls of the two movable grooves are slidably connected with connecting blocks 44. The front end of the front connecting block 44 is fixedly connected to the middle position of the top of the rear side of the inner rack frame 43, and push plates 45 are fixedly installed at the opposite ends of the two connecting blocks 44. A plurality of rectangular through grooves 46 arranged in a linear manner are provided on the right side of the push plate 45.

[0038] Through the reciprocating movement of the inner rack frame 43, the two connecting blocks 44 slide in the two moving grooves and drive the push plate 45 to move back and forth. When the push plate 45 moves back and forth, the silt entering the treatment box 5 can be pushed away, so that the silt can be quickly separated from the stones inside. When the silt contacts the push plate 45, it can flow down from a number of rectangular through grooves 46, and will not remain on the surface of the push plate 45 in large quantities, thereby not affecting the reciprocating movement of the push plate 45.

[0039] like Figure 5 As shown, a screening plate 47 is fixedly installed in the middle of the inner wall of the processing box 5, and a plurality of linearly arranged strip grooves are opened on the upper end of the screening plate 47. The screening plate 47 is located below the push plate 45. A collecting box 48 is slidably connected to the bottom of the inner wall of the processing box 5. A collecting groove is opened on the left side of the processing box 5, and the collecting box 48 is located directly to the left of the collecting groove.

[0040] The silt and stones are screened by the screening plate 47, and the larger stones remain on the screening plate 47, while the flowing silt enters the collecting box 48 through a plurality of strip grooves, and due to the action of the push plate 45, the silt can be evenly dropped into the collecting box 48. After the subsequent dredging work is completed, the collecting box 48 can be slid out of the collecting trough.

[0041] The working principle of the utility model is as follows: the staff pushes the device to the position where silt needs to be cleared, starts the electric transmission belt 22 and the motor 41, and when the mobile base 1 moves, a large amount of silt enters the silt clearing bucket 39, and the electric transmission belt 22 can transfer the silt to the processing box 5 through a plurality of L-shaped silt clearing plates 23. At the same time, the output end of the motor 41 drives the incomplete gear 42 to rotate, and the inner rack frame 43 drives the push plate 45 to move back and forth by meshing with the incomplete gear 42. The push plate 45 pushes the fallen silt back and forth above the screening plate 47, and the silt and stones are separated by the screening plate 47, and the silt falls evenly into the collection box 48.

[0042] After the dredging work is finished, the staff can slide and pull out the collection box 48 through the collection trough, and the silt in the collection box 48 needs to be transported to a designated treatment location. At the same time, the staff can classify the stones on the screening plate 47 and use the stones in other construction areas.

[0043] Subsequently, the staff rotates the hand wheel 34, which drives the reverse double-threaded rod 33 to rotate, and the two moving blocks 35 move away from each other by being threadedly connected with the reverse double-threaded rod 33. The two moving blocks 35 drive the two plug rods 310 to disengage from the two plug holes at the same time, so that the dredging bucket 39 is released, and the staff pulls out the dredging bucket 39, which moves out by sliding in the two T-shaped slides 38 in the two T-shaped slide grooves. After cleaning or replacing the dredging bucket 39, the staff slides it to its original position, rotates the hand wheel 34 until the two plug rods 310 move to their original positions, and the two plug rods 310 fix the two fixing blocks 311, so that the dredging bucket 39 can be quickly fixed to facilitate the next dredging work.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
