Technical Field

[0001] This utility model relates to the field of dredging equipment technology, and in particular to a grab bucket structure for a grab bucket boat. Background Technology

[0002] Grab bucket vessels are engineering vessels widely used in water operations. Their main function is to grab, transport, and unload materials from the seabed and surface using grab buckets. As a key working component of grab bucket vessels, the structural design of the grab bucket directly determines the key performance indicators of the vessel's operating efficiency, applicable scope, and reliability. With the rapid development of the global economy, the fields of marine resource development, port construction, and river dredging in water engineering are showing a booming trend. The grab bucket structure of grab bucket vessels is constantly being optimized to adapt to the requirements of deep sea, harsh sea conditions, and grabbing large particles of materials, thereby improving mining efficiency, reducing costs, and providing strong support for the development of the marine energy industry. This also sets higher standards for the grabbing capacity, operating speed, and reliability of grab bucket vessels, prompting the development of grab bucket structures towards larger and more efficient directions to meet the increasingly busy port logistics needs. These vessels can accurately clean silt and debris from the bottom of river channels, ensuring the safety and efficiency of inland waterway transportation and promoting economic exchange and development along inland waterways.

[0003] A search revealed Chinese Patent Publication No. CN114215133A, which discloses a grab bucket structure and rock-grabbing method for a grab bucket boat. The grab bucket structure includes a grab bucket base, with a fixed rake claw mounted at the lower end and a rotating rake claw mounted on the side. Two first supports extend from the grab bucket base towards the rotating rake claw, spaced apart. A rotating shaft rotatably connects the two first supports, and a transmission gear is mounted on the shaft. This transmission gear meshes with a gear pair rotatably mounted on the first supports. A mounting frame is located on the grab bucket base above the first supports, and the mounting frame is equipped with… The invention includes a hydraulic cylinder, with its telescopic shaft fixed to a gear pair. A swing arm is also fixed to the shaft body, and the suspended end of the swing arm is hinged to the upper end of the rotating rake claw. A connecting rod is also hinged to the rotating rake claw, and the suspended end of the connecting rod is hinged to the grab bucket seat below the first support. The grab bucket structure provided by this invention can ensure the rock-grabbing effect and improve the rock-grabbing efficiency. However, the above structure does not take the grabbing effect into account. The design of the structure cannot be used for heavy weights and large-scale applications. Moreover, the structure is relatively complex, lacks sealing, and is prone to spillage, affecting the grabbing efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a grab bucket structure for a grab bucket boat, which aims to improve the poor applicability of the existing technology in terms of scale and the problem that it is easy to spill out when working in a closed environment, thus affecting work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grab bucket structure for a grab bucket boat, comprising a bucket frame, a connecting frame fixedly connected to the top center of the bucket frame, multiple hydraulic rods fixedly connected to the bottom left and right sides of the connecting frame, a combination frame fixedly connected to the bottom end of the hydraulic rods, multiple sliders fixedly connected to the bottom front and rear sides of the combination frame, multiple assembly blocks fixedly connected to the front and rear sides of the bucket frame, multiple bucket bodies rotatably connected to the inner wall left and right sides of the assembly blocks, a sealing plate fixedly connected to the top of the bucket body, multiple guide rails fixedly connected to the top front and rear sides of the sealing plate, and a disassembly and assembly mechanism provided at the bottom of the bucket body for disassembling and replacing the protective structure.

The top of the bucket body 8 is fixedly connected to the sealing plate 9, which is in turn fixedly connected to the guide rail 10. When the slider 6 moves up and down, the bucket body 8 achieves opening and closing operation due to the sliding limit effect of the guide rail 10. This structure, through multiple power sources, increases power output, improves adaptability to heavy loads, and is relatively enclosed, improving working effect and efficiency, and meeting usage requirements.

[0048] The independently installed bucket shovel 201 allows for the replacement of easily damaged gripping contact points. An installation slot 202 is provided on the bucket shovel 201. During assembly, it is inserted into the bottom contact surface of the bucket body 8 through the installation slot 202 for initial installation. Since the bucket body 8 and the bucket shovel 201 have installation holes 203 and threaded holes 204 respectively, the two holes can be aligned after initial installation. Then, screws 205 are passed through the two holes and tightened to lock the connection, completing the installation. Furthermore, bucket teeth 206 are provided on the bucket shovel 201. During operation, the bucket teeth 206 can mesh with each other. This structure facilitates rock gripping, further improves the sealing effect, reduces leakage, and simplifies disassembly and assembly, extending the service life of the structure and meeting disassembly and assembly requirements.
