[0002] In the field of water conservancy engineering, the regular maintenance and cleaning of river channels is also an important part. Dredging buckets are engineering machinery attachments specially designed to clean silt and debris from the bottom of water bodies, and are usually installed on equipment such as excavators and grab buckets.

[0003] For example, China Utility Model Patent No. 202121307388.1 provides a "shovel bucket for river dredging". This patent includes a bucket body and a toothed claw connecting rod. The bucket body is U-shaped. The height of the two sides of the bucket body gradually decreases from back to front. A cantilever connector is installed at the middle of the top of the bucket body, which facilitates the removal of larger stones in the river and also has the function of screening mud and sand.

[0004] While the aforementioned document addresses the issue that current excavator buckets used for river dredging can only excavate silt and cannot effectively screen stones and gravel, they still suffer from the drawback of not being able to be quickly disassembled. The buckets lack a convenient disassembly structure, resulting in severe wear during long-term silt and gravel excavation. Furthermore, different specifications and types of buckets are used depending on the dredging needs, making a convenient disassembly structure particularly important. Therefore, this document introduces a detachable and replaceable dredging bucket. Utility Model Content

A fixing rod 11 is fixedly connected to one side of the 6, and mounting sleeves 12 are fixedly connected to both sides of the fixing rod 11. The excavator swing arm is fixedly connected to the mounting sleeves 12 by mounting pins. Then, the bucket body 1 is moved to the mounting bracket 6 on one side of the mounting sleeve 12 and inserted into the through groove 3 on the surface of the positioning plate 2. The clamping plate 5 at the bottom of the mounting bracket 6 is inserted into the clamping groove 4. The long bolt 9 is rotated. The long bolt 9 rotates in the inner cavity of the threaded sleeve 8 and slowly moves down, thereby driving the pressing seat 10 to press against the inner cavity of the fixing seat 7. In this way, the bucket body 1 is installed on the swing arm of the excavator, and it is convenient to disassemble quickly.

[0024] This technical solution incorporates a positioning plate 2, a through groove 3, a slot 4, a clamping plate 5, a mounting bracket 6, a fixing seat 7, a threaded sleeve 8, a long bolt 9, and a pressing seat 10. It provides a convenient disassembly and assembly structure on the bucket body 1, allowing the bucket body 1 to be easily and quickly installed on the excavator's boom, and facilitating quick disassembly, maintenance, or replacement. Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figures 1-3 As shown, the bottom of the inner cavity of the bucket body 1 is provided with a toothed claw 13, the distance between the teethed claws 13 is 10cm, and the two sides of the bucket body 1 are provided with waist-shaped holes 14. The inner cavity of the waist-shaped hole 14 is movably connected to a cleaning frame, and the top of the positioning plate 2 is fixedly connected to a limit sleeve. The inner cavity of the limit sleeve is movably connected to the surface of the long bolt 9.

[0026] The above technical solution is mainly used to achieve the purpose of screening, drainage and limiting the long bolt 9. Several equally spaced and parallel toothed claws 13 can effectively screen larger stones in the river silt. Water in the silt and gravel can be discharged from the waist-shaped hole 14, and the cleaning frame in the waist-shaped hole 14 can be easily pulled out, thereby removing the blockage in the waist-shaped hole 14. The limiting sleeve is wrapped around the surface of the long bolt 9, which not only enables the long bolt 9 to rotate stably, but also prevents the long bolt 9 from falling off. Example 3:

The fastening bolts are inserted into the holes on the surface of the fixing frame 15 and the positioning frame 16 to further fix the mounting frame 6. The wear-resistant plate made of alloy steel is extremely wear-resistant, so that the bottom of the bucket body 1 will not be excessively worn. The tapered inclined plug is more conducive to the bucket body 1 scooping out silt and gravel.

[0029] The working principle of this utility model is as follows: First, the mounting sleeve 12 on one side of the mounting bracket 6 is connected to the swing arm of the excavator. Then, the bucket body 1 is moved to the mounting bracket 6 on the side of the mounting sleeve 12 and inserted into the through groove 3 on the surface of the positioning plate 2. The retaining plate 5 at the bottom of the mounting bracket 6 is inserted into the retaining groove 4. The long bolt 9 is rotated. The long bolt 9 rotates in the inner cavity of the threaded sleeve 8 and slowly moves down, thereby driving the pressing seat 10 to press against the inner cavity of the fixing seat 7. In this way, the bucket body 1 is installed on the swing arm of the excavator. When the bucket body 1 is excessively worn during long-term use and needs to be disassembled for repair or replacement, the above installation steps can be reversed for quick disassembly.
