Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a double-bottom-plate sand bailing drill bucket. Background Art

[0002] Sand dredging buckets are a vital piece of equipment widely used in construction projects, primarily for drilling and dredging sand. They typically consist of a drill barrel, base plate, and various structural components, utilizing specialized mechanical mechanisms to achieve both drilling and dredging. The efficiency and stability of sand dredging buckets are crucial to the progress and quality of construction projects. Their design must consider multiple factors, including adaptability to varying geological conditions, dredging capacity, and ease of operation.

[0003] In existing engineering construction scenarios, traditional sand dredging buckets have many disadvantages in terms of cutting teeth replacement. First, at some construction sites, some sand dredging buckets use a rotary assembly method to install the cutting teeth. In this case, when the cutting teeth are worn and need to be replaced, since there is often a large amount of sand and soil in the construction environment, the sand and soil can easily penetrate into the assembly part during the disassembly process, making disassembly difficult and greatly reducing the replacement efficiency. For example, when performing a cutting tooth replacement operation, the staff needs to spend a lot of time and energy to clean up the infiltrated sand and soil before they can proceed to the next step of disassembly. Moreover, the infiltration of sand and soil also causes damage to the assembly part, affecting the service life of the equipment. Therefore, the technology in this field proposes a double-bottom plate sand dredging bucket to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a double-bottom plate sand dredging bucket, which aims to improve the problem that the picks at the bottom of the sand dredging bucket in the existing technology are easily penetrated by sand and soil after long-term use, and are inconvenient when they are severely worn and need to be replaced.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-bottom-plate sand dredging bucket, comprising a drill barrel and a plurality of leak-proof components, wherein the top of the drill barrel is fixedly connected to an assembly frame, the outer side of the drill barrel is rotatably connected to a rotating shaft, the outer side of the rotating shaft is fixedly connected to a first bottom plate, the leak-proof component is arranged on the outer side of the first bottom plate, and the leak-proof component is used to prevent the internal sand from leaking out when dredging sand, one side of the first bottom plate is rotatably connected to a second bottom plate, one side of the second bottom plate is fixedly connected to two combination plates, and a plurality of disassembly and assembly components are arranged on the outer side of the combination plate, and the disassembly and assembly components are used to conveniently replace the structural parts at the bottom of the drill barrel;

[0006] The disassembly and assembly assembly includes a mounting sleeve, which is fixedly connected to the outer side of the combination plate. A mounting groove is provided inside the mounting sleeve, and two limit grooves are provided on the inner wall of the mounting groove. Two combination grooves are provided inside the mounting sleeve, and two arc grooves are provided on the outer side of the mounting sleeve. Two U-shaped blocks are provided inside the mounting sleeve, and a pick is provided inside the mounting sleeve. The outer side of the pick is fixedly connected to two limit blocks, and the inside of the pick is provided with two card slots.

[0007] Furthermore, the outer side of the pick is slidably connected to the inner side of the mounting groove, and the outer side of the limiting block is slidably connected to the inner side of the limiting groove.

[0008] Furthermore, the combined groove and the arc groove intersect each other, and the outer side of the U-shaped block is slidably connected to the inner side of the combined groove.

[0009] Furthermore, the two ends of the U-shaped block are engaged in the two slots, and the slots are connected to the combination slots.

[0010] Furthermore, the leakage-proof component includes a fixed plate, one side of which is fixedly connected to the top of the base plate 1, and the interior of the base plate 1 is rotatably connected to a rotating column.

[0011] Furthermore, two arc-shaped telescopic rods are fixedly connected to the outer side of the rotating column, and springs are sleeved on the outer sides of the arc-shaped telescopic rods.

[0012] Furthermore, a semicircular plate is rotatably connected to the top of the base plate 1, and one end of the arc-shaped telescopic rod is fixedly connected to the outer side of the semicircular plate.

[0013] Furthermore, one end of the spring is fixedly connected to the outer side of the semicircular plate, and the other end of the spring is fixedly connected to the outer side of the rotating column.

[0014] The utility model has the following beneficial effects:

[0015] 1. In this utility model, the pick is inserted into the mounting slot, and the stopper is locked into the stopper slot. The slot is now connected to the combination slot, and the U-shaped block is inserted to connect the two to limit the pick and prevent it from falling. When the pick is worn and needs to be replaced, a metal hook is inserted into the arc slot to pull out the U-shaped block, and then the stopper block is hammered to remove the pick. Compared with the rotary assembly method, this replacement method is not affected by sand and soil infiltration, which improves replacement efficiency.

[0016] 2. In the present invention, when the bottom of the drill tube is closed by the bottom plates 1 and 2, the spring exerts its elastic force, so that one side of the semicircular plate is tightly sealed with the opening of the drill tube at the position of the rotating shaft. This can effectively prevent the sand and soil inside the drill tube from scattering, and improve the stability of the salvaged sand and soil. In actual sand bailing operations, this design can ensure that the sand and soil are safely stored inside the drill tube, reduce the loss of sand and soil, and provide a strong guarantee for efficient sand bailing operations.

The leak-proof component is arranged on the outer side of the bottom plate 1 4, and the leak-proof component is used to prevent the internal sand from leaking out when bailing sand, thereby ensuring the efficient implementation of the sand bailing operation. One side of the bottom plate 1 4 is rotatably connected to the bottom plate 2 5, and the bottom plate 2 5 works together with the bottom plate 1 4 to jointly close the bottom of the drill tube 1. One side of the bottom plate 2 5 is fixedly connected to two combination plates 6, and the combination plate 6 provides an installation basis for subsequent structural parts. A plurality of disassembly and assembly components are provided on the outside of the combination plate 6. The disassembly and assembly components are used to conveniently replace the structural parts at the bottom of the drill tube 1. The disassembly and assembly components include a mounting sleeve 7, which is fixedly connected to the outside of the combination plate 6 to provide installation space for other components. A mounting groove 8 is provided inside the mounting sleeve 7. The mounting groove 8 is used to accommodate the cutting tooth 13. The inner wall of the mounting groove 8 is provided with two limiting grooves 9, which cooperate with the limiting block 14 on the outside of the cutting tooth 13 to ensure the installation of the cutting tooth 13 The position is accurate, and two combination grooves 10 are provided inside the mounting sleeve 7. The combination grooves 10 provide a channel for the installation of the U-shaped block 12. The outer side of the mounting sleeve 7 is provided with two arc grooves 11. The arc groove 11 provides an operating space for replacing the pick 13. Two U-shaped blocks 12 are provided inside the mounting sleeve 7. The U-shaped blocks 12 are used to limit the pick 13 to prevent the pick 13 from falling from the inside of the mounting sleeve 7. The mounting sleeve 7 is provided with a pick 13 inside.

The inside of the pick 13 is provided with two The slots 15 cooperate with the two ends of the U-shaped block 12 to limit the pick 13. The outer side of the pick 13 is slidably connected to the inner side of the mounting groove 8 to ensure that the pick 13 can be smoothly installed and removed. The outer side of the limit block 14 is slidably connected to the inner side of the limit groove 9 to ensure that the installation position of the pick 13 is accurate. The position of the combined groove 10 and the arc groove 11 intersect, which is convenient for operation. The outer side of the U-shaped block 12 is slidably connected to the inner side of the combined groove 10 to ensure that the U-shaped block 12 can be smoothly installed and removed. The two ends of the U-shaped block 12 are engaged in the inside of the two slots 15 to limit the pick 13. The slots 15 are connected to the combined groove 10 to ensure that the U-shaped block 12 can be smoothly inserted into the slots 15.

[0026] The U-shaped block 12 is inserted into the fixing groove 8 so that the fixing block 14 is in the correct position to be inserted into the fixing groove 9. The fixing block 14 is then inserted into the fixing groove 9 so that the fixing block 14 is in the correct position to be inserted into the fixing groove 9. The fixing groove 15 is then connected to the combination groove 10. Then, the U-shaped block 12 is inserted into the fixing groove 15 so that the combination groove 10 is connected to the fixing groove 15. This operation can have a good limiting effect on the fixing tooth 13 and can effectively prevent the fixing tooth 13 from accidentally falling out of the inside of the fixing sleeve 7. When the bottom end of the fixing tooth 13 is severely worn after long-term use and needs to be replaced, a metal hook can be used to penetrate the inner side of the U-shaped block 12 from the position of the arc groove 11. In this way, the U-shaped block 12 can be smoothly pulled out from the inside of the fixing sleeve 7. Then, the limiting block 14 can be gently hammered to easily remove the fixing tooth 13 from the inside of the fixing sleeve 7. Compared with the rotating assembly method, this replacement method is not easily affected by the infiltration of sand and soil, which greatly improves the efficiency of replacing the fixing tooth 13.

[0027] Reference Figure 3-Figure 5 The anti-leakage component includes a fixed plate 17, one side of the fixed plate 17 is fixedly connected to the top of the bottom plate 4, providing a mounting base for other components, the bottom plate 4 is internally rotatably connected to a rotating column 18, the rotating column 18 provides mounting support for the arc-shaped telescopic rod 19 and the spring 20, the outer side of the rotating column 18 is fixedly connected to two arc-shaped telescopic rods 19, the arc-shaped telescopic rod 19 provides a guide for the movement of the semicircular plate 16, the outer sleeve of the arc-shaped telescopic rod 19 is provided with a spring 20, the spring 20 provides elastic force for the semicircular plate 16, so that it can be tightly with the semicircular plate 16. The drill barrel 1 is closed at the opening at the position of the rotating shaft 3, and the top of the bottom plate 4 is rotatably connected to a semicircular plate 16.

The limit block 14 can be hammered to easily remove the pick 13 from the inside of the installation sleeve 7. Compared with the rotating assembly method, it is not easily affected by the infiltration of sand and soil.

[0030] In addition, when bottom plate 1 4 and bottom plate 2 5 close the bottom of the drill barrel 1, the elastic force of the spring 20 can push the semicircular plate 16 so that one side of the semicircular plate 16 is sealed with the opening of the drill barrel 1 at the position of the rotating shaft 3, thereby preventing the sand and soil inside the drill barrel 1 from scattering and improving the stability of the salvaged sand and soil.
