[0026] The swinging crushing mechanism comprises a frame 3 fixedly installed at the bottom of the dredging ship 1, a driving motor 4 fixedly connected to the outer side of the frame 3, a first rotating shaft 5 fixedly connected to the output shaft of the driving motor 4, a sector gear 6 fixedly connected to the outer surface of the first rotating shaft 5, a second rotating shaft 7 rotatably connected to the inner side of the frame 3, a driven gear 8 and a swinging frame 9 fixedly connected to the outer surface of the second rotating shaft 7, a rotary motor 10 fixedly connected to the outer side of the swinging frame 9, a roller 11 fixedly connected to the output shaft of the rotary motor 10, and a crushing rod 12 fixedly connected to the outer side of the roller 11. The inner side of the treatment box 2 is provided with a sludge treatment assembly. The driving motor 4 can drive the sector gear 6 to continuously rotate clockwise through the first rotating shaft 5, so as to drive the second rotating shaft 7 to intermittently rotate counterclockwise through the driven gear 8. During the intermittent rotation of the second rotating shaft 7, the swinging frame 9 is intermittently swung forward. At this time, the rotary motor 10 drives the crushing rod 12 on the roller 11 to continuously rotate, so as to continuously scrape the sludge on the riverbed and stir the already clumped sludge, thereby improving the sludge treatment efficiency.

[0027] It should be noted that when the toothed part of the sector gear 6 meshes with the driven gear 8, power is transmitted to the second rotating shaft 7 to realize movement, and when the toothless part of the sector gear 6 is turned to the driven gear 8, the second rotating shaft 7 stops rotating, thereby realizing intermittent movement.

[0028] In this embodiment, the sludge treatment assembly comprises a mounting plate 13, a collecting cylinder 14 and a sewage pump 15 fixedly connected to the inner side of the treatment box 2. The outer side of the mounting plate 13 is fixedly connected with a servo motor 16, and the output shaft of the servo motor 16 is fixedly connected with a sector blade 17. The top of the dredging ship 1 is fixedly connected with a confluence box 18 and a filter box 19. The servo motor 16 can drive the sector blade 17 to continuously rotate, so as to suck the already stirred sludge into the collecting cylinder 14 and further crush the sludge to reduce the volume of the sludge and avoid the situation of pipe blockage. At the same time, the sewage pump 15 can suck the water containing sludge in the collecting cylinder 14 into the confluence box 18 and the filter box 19 for filtration and separation.

[0029] Specifically, the mounting plate 13 is externally provided with an inlet and outlet, and the driving motor 4, the rotary motor 10 and the servo motor 16 are externally provided with waterproof covers.

[0030] It should be noted that the water inlet pipe and the water outlet pipe of the sewage pump 15 are respectively connected with the collecting cylinder 14 and the confluence box 18.

[0033] Specifically, the number of the sector gears 6 and the driven gears 8 is two, and the sector gears 6 and the driven gears 8 are symmetrically arranged on the inner side of the rack 3.

[0034] It should be noted that the processing box 2 is fixedly installed on one side of the rack 3 through the mounting frame.

[0035] The working principle of the above embodiment is as follows:

[0036] In use, the staff first needs to start the driving motor 4. The driving motor 4 can drive the sector gear 6 to rotate clockwise continuously through the first rotating shaft 5, so as to realize intermittent motion through the driven gear 8. At this time, the driven gear 8 drives the second rotating shaft 7 to rotate counterclockwise intermittently, so that the swing frame 9 swings forward intermittently. At this time, the rotary motor 10 is started, which can drive the crushing rods 12 on the roller 11 to rotate continuously, so as to continuously scrape the silt on the riverbed and stir the silt that has been agglomerated. Then, the servo motor 16 and the sewage pump 15 are started. The servo motor 16 can drive the sector blade 17 to rotate continuously, so as to suck the silt that has been stirred into the collecting cylinder 14 and further crush it. The sewage pump 15 can suck the water containing silt in the collecting cylinder 14 into the collecting box 18 and the filtering box 19 to filter and separate it. The water containing silt in the collecting box 18 is distributed through the three flow guides 20, so as to be evenly distributed on the filter screen 21 for filtering and separation. Finally, the silt is retained on the filter screen 21 for centralized cleaning, and the water is discharged from the drain pipe on the side of the filtering box 19.
