Specific implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] The following gives specific embodiments.

[0026] Such as Figures 1-5As shown in the figure, a dredging device for water conservancy projects includes a dredging machine main body 1; a conveying member 11 is installed in the middle of the dredging machine main body 1; a dredging plate 12 is installed at the end of the dredging machine main body 1; a bracket 13 is fixedly connected to the top of the dredging plate 12; a double-shaft motor 14 is installed in the middle of the bracket 13; the output ends of the double-shaft motor 14 are fixedly connected with reciprocating screws 15, and the reciprocating screws 15 are rotatably arranged in the middle of the bracket 13; a slider 16 is threadedly connected to the middle of the reciprocating screw 15, and the slider 16 is slidably arranged in the middle of the bracket 13; a connecting rod 17 is fixedly connected to the middle of the slider 16; a push plate 18 is fixedly connected to the end of the connecting rod 17, and the push plate 18 is slidably arranged in the middle; during operation, the staff needs to transfer it to the river channel position and control the overall dredging machine main body 1 to clean the silt in the river channel. At the same time, the moving conveying member 11 is used to transfer the position of the silt. By setting a bracket 13 on the top of the dredging plate 12, when there is more silt at the edge of the dredging plate 12, the staff can turn on the switch of the double-shaft motor 14, so that the output ends at both ends can synchronously drive the reciprocating screw 15 to rotate. During the movement of the reciprocating screw 15, the two push plates 18 can first move closer to the conveying member 11, and then move away, and transfer the silt at the edge of the dredging plate 12 and the push plate 18, so as to push it to the output end position of the conveying member 11. This step, combined with the two push plates 18 that can reciprocate, can improve the accuracy of the conveying member 11 in cleaning the silt later, reduce the problem of more silt accumulating at the edge of the dredging plate 12, making it troublesome to clean later, and at the same time, it can reduce the problem of the low storage space of the overall dredging plate 12 during the process of cleaning the silt.

[0027] As Figure 2 , 3As shown in FIGS. 3 and 4, a tooth block 2 is fixedly connected to the middle of the reciprocating screw 15; two groups of limiting members 21 are fixedly connected to the side wall of the bracket 13; a tooth rail 22 is slidably connected to the middle of the dredging plate 12, and the tooth rail 22 and the tooth block 2 are meshed with each other; two groups of shielding plates 23 are fixedly connected to the side wall of the bracket 13, and the middle of the shielding plate 23 is arc-shaped; two fixing rods 24 are fixedly connected to the middle of the tooth rail 22, and the fixing rods 24 are aligned with the edge of the shielding plate 23; during operation, two arc-shaped shielding plates 23 are arranged at the edge of the dredging plate 12, and when the conveying member 11 transfers the silt, the two shielding plates 23 can push and block the silt with a high accumulation, and during the operation of the double-shaft motor 14, the two reciprocating screws 15 can synchronously drive the tooth block 2 to rotate, and lift the whole tooth rail 22 upward until the edge of the fixing rod 24 is separated from the shielding plate 23, and after the tooth block 2 continues to rotate, the teeth in the middle thereof will be disengaged from the inner wall of the tooth rail 22. Under the drive of gravity, the fixing rod 24 will hit the top of the shielding plate 23 and generate a vibration force. This step in cooperation with the arranged shielding plate 23 can improve the cleanliness of the surface of the double-shaft motor 14, reduce the problem that a large amount of silt contacts the surface of the double-shaft motor 14 and cakes, so that the heat dissipation effect of the double-shaft motor 14 is low during subsequent operation, improve the stability of the double-shaft motor 14 during use, and when the arranged fixing rod 24 hits, it can reduce the accumulation time of a large amount of impurities at the bottom of the shielding plate 23.

[0028] As Figure 3 shown, an indented member 3 is fixedly connected to the top of the shielding plate 23; an impact ball 31 is fixedly connected to the end of the fixing rod 24, and the impact ball 31 and the inner wall of the indented member 3 are matched in shape; during operation, an impact ball 31 is arranged at the bottom of the fixing rod 24, and when the fixing rod 24 approaches the shielding plate 23, the impact ball 31 will get stuck at the inner wall of the indented member 3 and perform an impact operation, so as to be fitted together. This step in cooperation with the arranged impact ball 31 can increase the contact area when hitting the shielding plate 23, and at the same time, in cooperation with the indented member 3, it can limit the area when the fixing rod 24 impacts, and reduce the problem of deformation in the middle of the shielding plate 23 and slippage between the fixing rod 24 and the shielding plate 23.

[0029] As Figure 3 and 5 shown, a reinforcing block 4 is fixedly connected to the top of the tooth rail 22; a storage box 41 is fixedly connected to the top of the reinforcing block 4, and the inner wall of the storage box 41 is inclined; during operation, a reinforcing block 4 is arranged at the top of the tooth rail 22, and when the staff needs to adjust the gravity and speed of the overall descent of the tooth rail 22 subsequently, an appropriate amount of heavy objects can be placed into the storage box 41. This step in cooperation with the arranged storage box 41 and the heavy objects arranged inside can improve the flexibility of the tooth rail 22 during operation, and the reinforcing block 4 can reinforce the storage box 41.

[0030] As Figure 5 shown, a plurality of elastic ropes 5 are fixedly connected to the inner wall of the storage box 41; during operation, by arranging a plurality of elastic ropes 5 on the inner wall of the storage box 41, when placing heavy objects, the middle part of the storage box 41 can be pulled to deform, and the reset elastic ropes 5 can limit the heavy objects. This step in cooperation with the arranged elastic ropes 5 can reduce the problem that the heavy objects are separated from the storage box 41 due to inertia during the downward movement of the overall storage box 41.

[0031] As Figure 2 shown, a plurality of protruding blocks 6 are fixedly connected to the middle of the push plate 18, and the plurality of protruding blocks 6 are arranged in a linear array; during operation, by arranging a plurality of protruding blocks 6 in the middle of the push plate 18, when the push plate 18 pushes the silt, the uneven plurality of protruding blocks 6 will come into contact with the silt for work. This step in cooperation with the arranged protruding blocks 6 can improve the stability of the silt during movement and reduce the occurrence of the silt sliding.

[0032] As Figure 2 shown, a gasket 7 is fixedly connected to the inner wall of the bracket 13, and the gasket 7 is arranged at the bottom of the tooth rail 22; during operation, by arranging a gasket 7 on the inner wall of the bracket 13, when the tooth rail 22 falls, the gasket 7 made of soft material can contact its bottom. This step in cooperation with the arranged gasket 7 can protect the bottom of the tooth rail 22 and reduce the wear and deformation of the bottom of the tooth rail 22.

[0033] Working principle: After being transferred to the river channel position, the main body 1 of the dredger is controlled to clean the silt in the river channel as a whole. At the same time, the moving conveying member 11 is used to transfer the position of the silt. Since there is a bracket 13 on the top of the dredging plate 12, when there is more silt at the edge of the dredging plate 12, the staff can start the switch of the double-shaft motor 14, so that the output ends at both ends can synchronously drive the reciprocating screw 15 to rotate. During the movement of the reciprocating screw 15, the two push plates 18 can first approach the conveying member 11 and then move away, and transfer the silt at the edge of the dredging plate 12 and the push plate 18, so as to push it to the output end position of the conveying member 11. Since there are two arc-shaped baffle plates 23 at the edge of the dredging plate 12, when the conveying member 11 transfers the silt, the two baffle plates 23 can push and block the silt piled up higher. During the operation of the double-shaft motor 14, the two reciprocating screws 15 can synchronously drive the tooth block 2 to rotate, and lift the whole tooth rail 22 upward until the edge of the fixed rod 24 is separated from the baffle plate 23. After the tooth block 2 continues to rotate, the teeth in the middle of it will be disengaged from the inner wall of the tooth rail 22. Driven by gravity, the fixed rod 24 will hit the top of the baffle plate 23 and generate a vibration force. Since there is an impact ball 31 at the bottom of the fixed rod 24, when the fixed rod 24 approaches the baffle plate 23, the impact ball 31 will get stuck at the inner wall of the recessed part 3 and perform the impact work, so as to fit together. Since there is a reinforcing block 4 on the top of the tooth rail 22, when the staff needs to adjust the gravity and speed of the whole tooth rail 22 to drop subsequently, an appropriate amount of heavy objects can be placed inside the storage box 41. Since there are multiple elastic ropes 5 on the inner wall of the storage box 41, when placing the heavy objects, the middle part of the storage box 41 can be pulled to deform, and the reset elastic ropes 5 can limit the heavy objects. Since there are multiple raised blocks 6 in the middle of the push plate 18, when the push plate 18 pushes the silt, the uneven multiple raised blocks 6 will come into contact with the silt. Since there is a gasket 7 on the inner wall of the bracket 13, when the tooth rail 22 falls, the gasket 7 made of soft material can contact its bottom.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
