Description

Technical Field

[0001] This utility model relates to the field of cutter suction dredger technology, and in particular to a self-cleaning cutter head structure for a cutter suction dredger. Background Technology

[0002] A cutter suction dredger is a specialized engineering vessel used for dredging projects and water development. Its core working principle involves a rotating cutter head at the bow to break up and loosen sediments such as silt and gravel from riverbeds, seabeds, or lake bottoms. Then, a high-pressure pump inside the vessel generates powerful suction, drawing the shredded slurry through a suction pipe into the hull, and finally transporting it to a designated area via a discharge pipe. This achieves integrated underwater excavation and transportation. However, traditional cutter suction dredgers lack protective mechanisms for the cutter head. During operation, the high sand content of the soil causes severe wear on the cutter head ring, averaging about 1.5 cm of wear per month. This rapid wear of the cutter head during operation results in low efficiency.

[0003] Existing patent CN207714406U discloses a protective dredging cutterhead, comprising a cutter arm, a cutter head ring, and an annular protective plate. The cutter arm has a cutter tooth seat with cutter teeth mounted on it. The cutter head ring is mounted on the cutter arm and has an annular protective plate. This prior art has advantages such as simple structure, convenient use, low cost, economic practicality, safety and environmental protection, significant effect, and wide applicability. This utility model can protect the cutter head ring, effectively reduce wear, save repair time, increase construction time utilization, and extend the service life of the cutter.

[0004] However, in the aforementioned existing technologies, conventional reamers need to be cleaned after use, but traditional cleaning methods are slow and ineffective, thus affecting subsequent use. Utility Model Content

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please see Figures 1-10 This utility model provides a self-cleaning cutter head structure for a cutter suction dredger, including multiple cleaning components, an annular telescopic hose 1, and a cutter head body 2. The cleaning components include a water collection body 3 and a telescopic component. The lower end face of the water collection body 3 is provided with multiple high-pressure nozzles 4. A connecting hose 5 is provided on the water collection body 3. A high-pressure water connector 6 is provided on the annular telescopic hose 1. A connecting cylinder 7 is provided on the cutter head body 2. The water collection body 3 is fixedly connected to the telescopic component and is located at the moving end of the telescopic component. The telescopic component is located outside the connecting cylinder 7, and the cleaning components are arranged in annular form around the outside of the connecting cylinder 7. The annular telescopic hose 1 is arranged around the outside of the multiple cleaning components, and each connecting hose 5 is connected to the annular telescopic hose 1 and located inside the annular telescopic hose 1.

[0026] In this embodiment, the multiple high-pressure nozzles 4 arranged on the lower end face of the water collection body 3 in the cleaning assembly can generate a powerful water flow to thoroughly rinse the auger body 2 after being connected to a high-pressure water source, effectively removing mud, sand, and debris attached to the auger and greatly improving cleaning efficiency. The telescopic component is fixedly connected to the water collection body 3, and the cleaning assembly is arranged in a ring around the outside of the connecting cylinder 7, allowing the water collection body 3 to be adjusted as needed, further ensuring no dead angles in the cleaning. The annular telescopic hose 1 is arranged around the outside of the multiple cleaning components and is connected to each of the connecting hoses 5, which can stably deliver high-pressure water to each water collection body 3, ensuring the continuity and stability of the water flow during the cleaning process. This effectively solves the problems of slow efficiency and poor effect of traditional cleaning methods and provides a reliable guarantee for the subsequent use of the auger.

[0027] Further, the telescopic component includes a telescopic rod 8, two support blocks 9, and a telescopic cylinder 10. One end of the telescopic rod 8 is provided with a sliding piece 11, and a locking block 12 is provided on the sliding piece 11. The telescopic cylinder 10 has a telescopic groove 13 inside and an adjustment groove 14 on the outside of the telescopic cylinder 10. Both ends of the adjustment groove 14 have locking slots 15, and the telescopic rod 8, the adjustment groove 14, and the locking slots 15 are in a connected state. The telescopic rod 8 is slidably connected to the telescopic cylinder 10 through the sliding piece 11 and is located inside the telescopic cylinder 10. The sliding piece 11 is located inside the telescopic groove 13, and the locking block 12 abuts against the corresponding locking slot 15. The water collection body 3 is provided at one end of the telescopic rod 8, and the telescopic cylinder 10 is hinged between the two support blocks 9. The two support blocks 9 are located outside the connecting cylinder 7.

[0028] In this embodiment, this design allows the telescopic rod 8 to extend and retract flexibly within the telescopic cylinder 10. By cooperating with the locking block 12 and the locking slots 15 at different positions, the extension length of the telescopic rod 8 can be precisely adjusted, thereby facilitating the adjustment of the position of the water collection body 3. This allows it to be more accurately aligned with the parts of the auger body 2 that need to be cleaned, improving the targeting and effectiveness of the cleaning.

[0029] Furthermore, one of the support blocks 9 is provided with a mounting box 16, and a worm gear 17 is rotatably disposed inside the mounting box 16. The worm gear 17 is rotated by a knob 18. A worm wheel 19 is disposed on the rotating shaft of the telescopic cylinder 10, and the worm gear 17 meshes with the worm wheel 19 and is located below the worm wheel 19.

[0030] In this embodiment, when the knob 18 is turned, the worm gear 17 rotates accordingly, which in turn drives the worm wheel 19 to rotate, causing the telescopic cylinder 10 to rotate around its rotation axis. This transmission method has self-locking properties and can remain stable after being adjusted to a suitable angle. It will not easily change the angle due to external forces. Through this angle adjustment function, the spray direction of the water collection body 3 can be further adjusted, so that the high-pressure nozzle 4 can clean the auger body 2 from different angles, which greatly improves the flexibility and comprehensiveness of cleaning and can better adapt to the cleaning needs of the auger under various complex working conditions, effectively improving the cleaning effect.

[0031] Furthermore, the self-cleaning cutter head structure for the cutter suction dredger also includes a protective cylinder 20. One end of the protective cylinder 20 has a through hole 21, and the other end of the protective cylinder 20 is provided with a first magnetic suction piece 22. The end of the connecting cylinder 7 near the cutter head body 2 is provided with a second magnetic suction piece 23. The protective cylinder 20 is slidably connected to the connecting cylinder 7 and is sleeved on the connecting cylinder 7. The multiple cleaning components and the annular telescopic hose 1 are all located inside the protective cylinder 20. The first magnetic suction piece 22 and the second magnetic suction piece 23 are magnetically connected.

[0032] In this embodiment, the protective cylinder 20 protects the internal cleaning components and the annular telescopic hose 1, preventing them from being impacted or worn during the operation of the auger, thus extending the service life of these components, reducing the maintenance cost of the equipment, and improving the reliability and stability of the entire self-cleaning auger structure.

[0033] Furthermore, a plurality of limiting blocks 24 are provided on the inner side of the through hole 21, and a plurality of limiting grooves 25 are provided on the outer side of the connecting cylinder 7, with the limiting blocks 24 located in the corresponding limiting grooves 25.

[0034] In this embodiment, this design plays a precise positioning and guiding role, ensuring that the protective cylinder 20 can be quickly and accurately positioned in the correct position during installation, thus avoiding installation deviation.

[0035] When using this utility model, first push the protective cylinder 20 away from the end of the auger body 2 to fully expose the cleaning component. Then, according to the part of the auger body 2 that needs to be cleaned, rotate the worm gear 17, which is rotated by the knob 18 in the mounting box 16 on one of the support blocks 9. Since the worm gear 17 meshes with the worm wheel 19 on the rotating shaft of the telescopic cylinder 10, it drives the telescopic cylinder 10 to rotate around its rotating shaft. Adjust the telescopic cylinder 10 to a suitable angle, and at the same time pull the telescopic rod 8 to make the sliding... The plate 11 slides within the telescopic groove 13 of the telescopic cylinder 10 to adjust the extension length of the telescopic rod 8, thereby adjusting the water collection body 3 to a suitable position and angle. The locking block 12 abuts against the corresponding locking groove 15. Then, the high-pressure water connector 6 on the annular telescopic hose 1 is connected to a high-pressure water source. The high-pressure water enters the water collection body 3 through the annular telescopic hose 1 and each of the connecting hoses 5, and finally sprays out from the multiple high-pressure nozzles 4 on the lower end face of the water collection body 3 to perform all-round, multi-angle, and efficient cleaning of the auger body 2.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
