Description

Technical Field

[0001] This utility model relates to the field of river dredging technology, specifically to a river dredging device. Background Technology

[0002] River dredging generally refers to the management of river channels. It is a water conservancy project that uses mechanical equipment to blow and stir up the silt deposited on the riverbed into a turbid water state, which is then carried away by the river water, thereby achieving the purpose of clearing the water.

[0003] During river dredging, stones are often found in the riverbed due to natural sedimentation and water transport. However, traditional dredging equipment lacks a structure to handle these stones, making it difficult to remove them effectively from the dredging pipe inlet. When processing silt containing stones, these stones are easily sucked up along with the dredging pipe. Once inside, these stones can easily cause blockages, requiring equipment shutdown for cleaning or maintenance. This not only interrupts dredging operations and reduces their continuity but also increases the risk of equipment damage. Furthermore, the presence of stones restricts the flow of silt, reducing the efficiency of the dredging pipe in subsequent silt extraction and affecting its overall usability.

[0004] Therefore, we have proposed a river dredging device to solve the above problems. Utility Model Content

[0025] In the embodiment, as Figure 1 and Figure 2As shown, the upper end surface of the fixed block 12 is rotatably connected with a connecting rod 14, the connecting rod 14 is rotatably connected with a circular ring 9 at the end away from the fixed block 12, the circular ring 9 is sleeved on the outer surface of the silt pumping pipe 1, when the circular ring 9 reciprocates on the outer surface of the silt pumping pipe 1, the connecting rod 14 can push the fixed block 12 to move synchronously.

[0026] In this embodiment, as shown in Figure 1 and Figure 4 As shown, the upper end surface of the circular ring 9 is fixedly connected with a connecting column 7, the outer surface of the connecting column 7 is slidably connected with a supporting block 8, the supporting block 8 is fixedly connected to the outer surface of the blowdown pipe 2, the upper end of the connecting column 7 is fixedly connected with a connecting plate 6, the two connecting plates 6 are fixedly connected with a connecting ring 22, the connecting ring 22 is sleeved on the outer surface of the rotating shaft 4, when the connecting ring 22 moves up and down on the outer surface of the rotating shaft 4, the connecting plate 6 can pull the connecting column 7 to slide synchronously on the supporting block 8, and drive the circular ring 9 connected between the lower end of the connecting column 7 to reciprocate.

[0027] In this embodiment, as shown in Figure 4 As shown, the outer surface of the rotating shaft 4 is provided with a reciprocating groove 21, the reciprocating groove 21 is slidably connected with a ball 23, the ball 23 is fixedly connected to the inner wall of the connecting ring 22, when the rotating shaft 4 rotates, the position of the reciprocating groove 21 will also change, at this time, the reciprocating groove 21 will extrude the ball 23, push the ball 23 to slide along the path of the reciprocating groove 21, thereby driving the connecting ring 22 to reciprocate up and down on the outer surface of the rotating shaft 4.

[0028] In this embodiment, as shown in Figure 3 As shown, the outer surface of the silt pumping pipe 1 is fixedly connected with a fixed column 16, the fixed column 16 is slidably connected with a linkage frame 17, the linkage frame 17 is fixedly connected with a knocking plate 15 near the side of the silt pumping pipe 1, the linkage frame 17 and the outer surface of the silt pumping pipe 1 are fixedly connected with springs 18 symmetrically, the springs 18 are all sleeved on the outer surface of the fixed column 16, when the springs 18 pull the linkage frame 17 to slide on the fixed column 16 towards the silt pumping pipe 1, the knocking plate 15 can be driven to hit the outer surface of the silt pumping pipe 1.

[0029] In this embodiment, as shown in Figure 3 As shown, the linkage frame 17 is fixedly connected with a fixed plate 19 symmetrically near the side of the silt pumping pipe 1, the fixed plate 19 is provided with a push rod 20 away from the linkage frame 17, the push rod 20 is fixedly connected to the connecting column 7, the upper end surface and the lower end surface of the fixed plate 19 near the push rod 20 are both inclined, when the push rod 20 moves vertically up and down with the connecting column 7, the connecting rod 14 will push the fixed plate 19 through the inclined surface, so that the linkage frame 17 is driven to move.

[0030] The effects achieved by the embodiment are as follows: in the prior art, the traditional dredging equipment is not provided with a corresponding structure for processing stones, so it cannot timely and effectively push the stones away from the inlet of the dredging pipe 1. In the subsequent treatment of sludge containing stones, these stones are easy to be sucked together with the dredging pipe 1, and once these stones enter the interior of the dredging pipe 1, they can easily cause pipe blockage, so that the equipment needs to be stopped for cleaning or maintenance, which not only interrupts the dredging operation and reduces the continuity of the dredging operation, but also increases the risk of equipment damage. At the same time, due to the presence of stones, the fluidity of the sludge is also limited, which reduces the efficiency of the dredging pipe 1 in subsequent sludge suction, and further affects the use. Compared with the prior art, the dredging pipe 1 can drive the surrounding moving frame 10 to reciprocate during the process of dredging the river channel, so that the push rod 11 connected to the moving frame 10 pushes the stones around the inlet of the dredging pipe 1 away, and simultaneously reciprocates and stirs around the dredging pipe 1. Not only can it effectively avoid the blockage of the dredging pipe 1 by stones, ensure the continuity and efficiency of the dredging operation, but also the design of reciprocating stirring can make the sludge fully loosen and evenly disperse, thereby reducing the viscosity and density of the sludge, and then separating the sludge from the riverbed, making it easier to be sucked into the dredging pipe 1, and improving the dredging efficiency.

[0031] The working process and principles involved in the above embodiment are as follows:

[0032] When the staff places the dredging pipe 1 in the river channel, then opens the driving motor 5 to drive the rotating shaft 4 to rotate, so that the spiral blade 25 rotates in the dredging pipe 1, and at the same time, with the cooperation of the external dredging pump and the spiral blade 25, the silt in the river channel can be sucked into the dredging pipe 1 and transported to the drain pipe 2 for discharge. In the rotating process of the rotating shaft 4, the reciprocating groove 21 formed on the outer surface of the rotating shaft 4 will change synchronously. At this time, the ball 23 slidingly connected in the reciprocating groove 21 will be limited by the connecting ring 22 and cannot move synchronously with the reciprocating groove 21. Therefore, when the position of the reciprocating groove 21 changes, the ball 23 will slide in the reciprocating groove 21 along the path of the reciprocating groove 21, driving the connecting ring 22 to move up and down on the outer surface of the rotating shaft 4, and through the connecting plate 6 connected on both sides of the connecting ring 22, pulling the connecting column 7 to reciprocatingly lift on the supporting block 8. Since the lower end of the connecting column 7 is fixedly connected to the upper end surface of the circular ring 9, and the circular ring 9 is sleeved on the outer surface of the dredging pipe 1, with the reciprocating movement of the connecting column 7, the circular ring 9 can be lifted synchronously on the outer surface of the dredging pipe 1. At this time, during the descending process of the circular ring 9, the circular ring 9 will push the connecting rod 14 connected to the lower end surface to move synchronously, so that the connecting rod 14 moves from an inclined state to a horizontal state. With the change of the state of the connecting rod 14, the connecting rod 14 will push the fixed block 12 connected to the end away from the circular ring 9 to pull the telescopic column 13 to extend synchronously away from the dredging pipe 1. During the process that the fixed block 12 moves away from the dredging pipe 1, the moving frame 10 connected to the lower end will move synchronously, so that the push rod 11 connected to the lower end of the moving frame 10 can push the stones near the dredging pipe 1 away from the dredging pipe 1, effectively avoiding the situation that the stones block the dredging pipe 1, ensuring the continuity and efficiency of the dredging operation. Conversely, during the ascending process of the circular ring 9, the push rod 11 can be pulled to approach the dredging pipe 1 again through the connecting rod 14, the fixed block 12 and the moving frame 10 arranged, and so on. This can drive the push rod 11 to stir near the dredging pipe 1, so that the silt can be fully loosened and uniformly dispersed, thereby reducing the viscosity and density of the silt, and then separating the silt from the riverbed, making it easier to be sucked into the dredging pipe 1 and improving the dredging efficiency.

[0033] When the connecting column 7 reciprocatingly rises and falls on the supporting block 8, the push rod 20 connected with the outer surface of the connecting column 7 can move synchronously, at this time, since the upper and lower end faces of the side wall of the fixed plate 19 close to the push rod 20 are both inclined surfaces, and the fixed plate 19 is fixedly connected with the linkage frame 17, and the linkage frame 17 is slidingly connected with the fixed column 16, therefore, in the process of the push rod 20 descending or ascending, the push rod 20 will move along the inclined surface on the side wall of the fixed plate 19, and push the fixed plate 19 away from the connecting column 7, drive the linkage frame 17 to slide away from the silt pumping pipe 1 on the outer surface of the fixed column 16, and simultaneously pull the spring 18 connected between the linkage frame 17 and the silt pumping pipe 1, when the push rod 20 and the fixed block 12 are separated, through the rebounding force of the spring 18, the linkage frame 17 can reversely slide on the outer surface of the fixed column 16, at this time, the knocking plate 15 connected with the side wall of the linkage frame 17 will knock on the outer surface of the silt pumping pipe 1, which can weaken the adhesion of the silt, so that the silt can be more easily separated from the pipe wall, effectively prevent the silt from adhering to the pipe wall, and moreover, by means of synchronous knocking, the silt can be separated in time, thereby reducing the risk of pipe blockage caused by silt accumulation, and ensuring the smoothness of the silt pumping pipe 1.
