Description

Technical Field

[0001] The utility model relates to the technical field of dredging equipment, in particular to a river dredging device. Background Art

[0002] In river regulation and water resource protection work, river dredging is a crucial task. Traditional river dredging methods mostly adopt manual excavation or simple mechanical operations. These methods are not only inefficient but also difficult to ensure the uniformity and depth of dredging. In addition, with the accumulation of river silt, the navigation capacity, flood control capacity and water quality of the river will be seriously affected. Therefore, there is an urgent need for an efficient and flexible river dredging device. Traditional devices often rely on manual or simple mechanical operations, with slow dredging speed and low efficiency, making it difficult to meet the needs of large-scale river dredging. Many devices lack a depth adjustment function and cannot adjust the dredging depth according to the actual situation of the river, resulting in unsatisfactory dredging effects. Some devices are prone to shaking or tilting during dredging, affecting the accuracy and safety of dredging. The component designs of some devices are complex, making them difficult to disassemble and replace, increasing the difficulty and cost of maintenance. Content of the Utility Model

[0003] In order to solve the above problems, the utility model proposes a river dredging device to more precisely solve the problems raised in the above background art.

[0004] The utility model is achieved through the following technical solutions:

[0005] The utility model proposes a river dredging device, including a hull mounting plate. The top of the hull mounting plate is rotationally connected to a rotating cylinder through a bearing. A rotating rod is inserted into the top of the rotating cylinder. The rotating rod is inserted from the top of the rotating cylinder and rotates with the rotation of the rotating cylinder. An adjusting member is installed on the top of the hull mounting plate. The adjusting member is used to adjust the insertion depth of the rotating rod. The bottom surface of the rotating rod is detachably connected to a stirring cylinder. A plurality of stirring blades are installed on the surface of the stirring cylinder. A driving member is installed on the top of the hull mounting plate. The driving member is used to drive the rotation of the rotating cylinder.

[0019] In order to more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings.

[0020] Embodiment

[0021] As Figures 1-4 shown, a river dredging device proposed by an embodiment of the present utility model has a core structure including a hull mounting plate 1, which is designed to be fixed on the hull of a river dredging ship. At the top of the hull mounting plate 1, a rotating cylinder 2 is rotatably connected through a bearing, enabling the rotating cylinder 2 to rotate freely. A rotating rod 3 is inserted from the top of the rotating cylinder 2 and rotates synchronously with the rotation of the rotating cylinder 2. To adjust the insertion depth of the rotating rod 3, an adjusting member 5 is installed at the top of the hull mounting plate 1. In addition, a stirring cylinder 6 is installed at the bottom of the surface of the rotating rod 3 through a detachable connection method. A plurality of stirring blades 7 are evenly distributed on the outer surface of the stirring cylinder 6 for cutting and stirring the silt at the bottom of the river during rotation. To drive the rotation of the rotating cylinder 2, a driving member 4 is also installed at the top of the hull mounting plate 1. The device drives the rotation of the rotating cylinder 2 and the rotating rod 3 through the driving member 4, and the stirring cylinder 6 and the stirring blades 7 rotate accordingly, effectively cutting and stirring the silt at the bottom of the river to achieve the purpose of dredging. The adjusting member 5 allows adjusting the insertion depth of the rotating rod 3 according to the river depth and silt conditions, improving the dredging efficiency.

[0022] Among them, the specific structure of the adjusting member 5 includes a mounting bracket 51 installed on the top of the hull mounting plate 1. A support disk 52 is fixed at the end of the mounting bracket 51. The center of the support disk 52 is connected through the rotating rod 3, allowing the rotating rod 3 to rotate freely within the support disk 52. On the top of the support disk 52, a rotating disk 53 is rotatably connected through a bearing. The rotating disk 53 is sleeved on the surface of the rotating rod 3. In order to limit the up and down movement of the rotating rod 3, a limiting member 54 is installed on the rotating disk 53. A plurality of insertion holes 31 are opened along the length direction on the surface of the rotating rod 3. The limiting member 54 can be inserted into the insertion holes 31 at different positions, thereby fixing the insertion depth of the rotating rod 3. By rotating the rotating disk 53 and selecting an appropriate insertion hole 31 to insert the limiting member 54, the insertion depth of the rotating rod 3 can be conveniently adjusted to meet the dredging requirements of different river channels.

[0023] Among them, the specific structure of the limiting member 54 includes a spring 541 installed on the surface of the rotating disk 53. A connecting piece 542 is connected to the end of the spring 541. A plug rod 543 is fixed to the side of the connecting piece 542. When it is necessary to fix the insertion depth of the rotating rod 3, just gently push the connecting piece 542, so that the plug rod 543 is inserted into the corresponding insertion hole 31 on the rotating rod 3 under the action of the spring 541. The design of the limiting member 54 makes it simple and fast to adjust the insertion depth of the rotating rod 3, while ensuring the stability of the rotating rod 3 during the working process.

[0024] Among them, the specific structure of the driving member 4 includes a motor 41 installed on the top of the hull mounting plate 1. The output end of the motor is connected with a first gear disk 42. A second gear disk 43 meshing with the first gear disk 42 is fixed on the surface of the rotating cylinder 2. When the motor 41 is started, the first gear disk 42 drives the second gear disk 43 to rotate, thereby driving the rotation of the rotating cylinder 2 and the rotating rod 3. The design of the driving member 4 provides a stable and reliable driving force, ensuring the continuous rotation of the rotating cylinder 2 and the rotating rod 3, and improving the efficiency of dredging.

[0025] Among them, the detachable connection method between the mixing cylinder 6 and the rotating rod 3 is realized by installing a nut 61 on the surface of the mixing cylinder 6 and threadedly connecting a bolt 62 at the nut 61. The bolt 62 passes through the mixing cylinder 6 and is connected through the corresponding hole on the rotating rod 3. By tightening the bolt 62, the mixing cylinder 6 can be fixed on the rotating rod 3. This detachable connection method makes the replacement and maintenance of the mixing cylinder 6 simple and convenient, and also allows different mixing cylinders 6 to be selected according to actual needs to adapt to different dredging environments.

[0026] Among them, in order to ensure the stable rotation of the rotating rod 3 within the rotating cylinder 2, a limiting groove 21 is provided at the inner wall of the rotating cylinder 2, and a limiting strip 32 that is slidably connected to the inner wall of the limiting groove 21 is installed on the surface of the rotating rod 3. The cooperation between the limiting groove 21 and the limiting strip 32 effectively restricts the radial movement of the rotating rod 3 during rotation, ensures the stable rotation of the rotating rod 3 and the stirring cylinder 6, and improves the accuracy and efficiency of dredging and sediment removal.
