Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0036] Please see Figure 1-4 The present invention provides the following technical solution:

[0037] A high-efficiency river dredging machine, comprising:

[0038] A fixed frame 1 is fixedly connected to a fixed shell 2 at its upper end. A mud pump 3 is fixedly connected to the inner surface of the fixed shell 2. A mud pumping pipe 6 is provided on the lower side of the fixed frame 1.

[0039] Two mounting brackets 4 are fixedly connected to both sides of the fixed bracket 1, and two slide rails 5 are provided on the lower side of the two mounting brackets 4;

[0040] The fixed base 10 is fixedly connected to the upper inner wall of the fixed frame 1, and the upper end of the fixed base 10 is fixedly connected to the protective shell 11.

[0041] Two sets of crushing mechanisms, both located below the fixed frame 1, are used to crush debris and aquatic plants in the riverbed silt; and

[0042] The moving mechanism is set inside the fixed frame 1 to adjust the position of the two crushing mechanisms.

[0043] In a specific embodiment of this utility model, the fixed frame 1 provides a support structure for the entire device, ensuring that other components can be stably installed and operated. The fixed shell 2 is installed on the upper end of the fixed frame 1 and houses the mud pump 3, which is used to pump out a mixture of sludge and water. Two mounting brackets 4 are fixed to both sides of the fixed frame 1, thus cooperating with the two slide rails 5 to provide a track for the movement of the crushing mechanism, ensuring its linearity and stability. The mud pumping pipe 6 is located on the lower side of the fixed frame 1 and is connected to the mud pump 3 by a flexible hose, thereby pumping out the crushed sludge. The fixed seat 10 is fixed to the inner wall of the fixed frame 1, providing a stable mounting surface for the dual-shaft motor 12. The platform, with its protective shell 11 fixed to the upper end of the fixed base 10, protects the dual-axis motor 12 from external environmental influences. The output ends of the dual-axis motor 12 on both sides are connected and fixed to two lead screws 13. When the dual-axis motor 12 is started, it drives the two lead screws 13 to rotate. Two nuts 16 are threadedly connected to the circumferential surfaces of the two lead screws 13, moving as the two lead screws 13 rotate, thereby adjusting the position of the crushing mechanism below. One end of each of the four limiting rods 14 is fixed to the inner walls on both sides of the fixed frame 1, and the other end is fixed to both sides of the fixed base 10. Simultaneously, four limiting blocks 24 slide on the surfaces of the four limiting rods 14. When the two nuts 16 move, they simultaneously drive the four limiting blocks 24 to slide, ensuring... To ensure the accurate movement trajectory of the two nuts 16, the two sets of crushing mechanisms on the lower side are adjusted in position. The drive motor 19 is fixed to the upper end of the mounting base 18, and its output end extends through the inner surface of the mounting base 18. The first spur gear 22 is fixed to the output end of the drive motor 19. When the drive motor 19 is started, it drives the first spur gear 22 to rotate. At the same time, the first spur gear 22 meshes with multiple second spur gears 23, and the multiple second spur gears 23 mesh with the gear ring 21. Under the action of force, the multiple second spur gears 23 and the gear ring 21 rotate. The rotating gear ring 21 strengthens the rotational strength of the multiple second spur gears 23. The rotation of wheel 23 drives the multiple crushing rollers 25 on the lower side to rotate, thereby crushing debris and aquatic plants in the river silt. This improves the crushing efficiency of the river dredging machine for debris and aquatic plants in the silt, solves the problem of large debris or aquatic plants in the silt, avoids blockage of the sludge discharge pipe requiring manual inspection and dredging, improves the working efficiency of the river dredging machine, and reduces the waste of time and human resources.

[0064] The working principle and usage process of this utility model are as follows: First, the dual-shaft motor 12 is started to drive the two lead screws 13 to rotate. As the two lead screws 13 rotate, they move, causing the two nuts 16 to slide on the circumferential surface of the two lead screws 13. Under the action of force, the four limit blocks 24 slide on the surface of the four limit rods 14, thereby realizing the position adjustment of the two sets of crushing mechanisms on the lower side.
