Description

Technical Field

[0001] This invention belongs to the field of waterway construction technology, specifically a high-efficiency excavation device for waterway dredging construction. Background Technology

[0002] Channel dredging refers to engineering activities conducted using specialized equipment such as dredgers to excavate, deepen, widen, or clear underwater channels to ensure safe navigation. One of its core tasks is to remove silt, sediment, and other obstacles deposited in the channel to restore or maintain the designed navigable depth. During this process, dredging equipment plays a crucial role in directly grabbing, lifting, and transferring underwater materials.

[0003] In existing technologies, silt is often dredged using a bucket, and multiple drainage holes are installed on the bucket to prevent excess water from being carried out during dredging. However, after a period of use, a certain amount of silt also adheres to the walls of the drainage holes. With the increase in the number of operations, the adhered silt gradually thickens and hardens, causing the effective diameter of the drainage holes to shrink or even become completely blocked, thus losing its drainage function. Once the drainage holes are blocked, the bucket will scoop up a large amount of water while dredging silt, increasing the ineffective load of a single lift, resulting in energy waste, and also reducing the actual amount of silt that can be grabbed, seriously affecting dredging efficiency. Clearing such blockages requires stopping the machine and using manual labor or auxiliary tools for unblocking, which is inconvenient and time-consuming, further restricting the continuous operation capability of dredging.

[0004] Meanwhile, silt also adheres to the inner wall of the bucket. This not only reduces the effective volume of the bucket but also makes unloading difficult and increases the material residue rate. The problem of silt adhering to the inner wall, combined with the blockage of the drainage holes, further increases the resistance encountered by the bucket during operation and exacerbates the decline in digging efficiency. Summary of the Invention

The integrated sludge scraping and dredging component includes a scraping shell that can move inside the bucket body. Multiple through blocks that match the specifications of the drainage holes are slidably passed through one side of the scraping shell, and adjacent through blocks are fixedly connected by connecting blocks. The number of through blocks is the same as the number of drainage holes in a row. When the scraping shell moves inside the bucket body, multiple through blocks are aligned with multiple rows of drainage holes in sequence, and the through blocks push the sludge out through the drainage holes.

A slider is slidably arranged on the transverse frame along the vertical direction. A rotating plate is rotatably arranged on one side of the slider. The scraping shell is fixedly connected to the two rotating plates.

[0008] Preferably, the displacement component further includes a driving structure; The drive structure includes a lead screw three threadedly connected to the transverse frame. Both ends of the lead screw three are rotatably mounted on the bucket body. Motors six are fixedly mounted on both sides of the bucket body. The motors six on both sides are fixedly connected to the ends of the two lead screws three respectively. A lead screw two is threadedly connected to one side of the slider. Both ends of the lead screw two are rotatably mounted on the transverse frame. A motor five is fixedly mounted on the transverse frame. The output end of the motor five is fixedly connected to one end of the lead screw two. A motor three is fixedly mounted on one side of the slider. The output end of the motor three is fixedly connected to the rotating end of the rotating plate.

[0009] Preferably, an electric push rod is fixedly provided on one side of the inner cavity of the scraping shell, and the piston end of the electric push rod is fixedly connected to one side of the through block.

[0010] Preferably, the scraping shell is further provided with a dispersing component; The dispersing component includes multiple scrapers, each of which is rotatably mounted on a through block. The scrapers are in contact with the surface of the through block, and the surface of the scrapers is provided with multiple breaking teeth.

[0011] Preferably, a worm gear is fixedly sleeved on the rotating end of the scraper, a worm is rotatably mounted on the through block, the worm has multiple helical teeth, and each helical tooth meshes with a worm gear, and a motor is fixedly mounted on the through block, the output end of the motor being fixedly connected to one end of the worm.

[0012] Preferably, the bucket body is equipped with a mud-gathering component; The mud-gathering component includes a gathering port located in the middle of the bucket body, the gathering port being connected to a mud discharge pipe, a baffle being rotatably provided at the opening of the mud discharge pipe, and mud-gathering plates slidingly passing through both sides of the bucket body.

[0013] Preferably, a second motor is fixedly installed on the sludge discharge pipe, and the output end of the second motor is fixedly connected to one end of the baffle.

[0014] Preferably, a fixing plate is fixedly provided on one side of the bucket body, and sliding rods are slidably inserted into both sides of the inner cavity of the fixing plate, with one end of the sliding rod being fixedly connected to one side of the mud-gathering plate.

[0015] Preferably, a motor is fixedly installed in the middle of the inner cavity of the fixed plate, and a lead screw is fixedly installed on both sides of the output end of the motor. The lead screws on both sides are threadedly connected to the sliding rods on both sides respectively.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses a high-efficiency excavation device for waterway dredging construction. Utilizing an integrated scraping and unblocking component, it can clean silt adhering to the inner wall of the bucket body and the walls of the drainage holes with the cooperation of the scraping shell and the penetrating block. This solves the problem of reduced bucket capacity and difficulty in unloading caused by silt adhesion; simultaneously, it avoids the impact on drainage effect due to blockage of the drainage holes. The entire process requires no manual intervention or machine shutdown, ensuring continuous dredging operation, significantly improving excavation efficiency, and reducing energy waste.

[0017] 2. The high-efficiency excavation device for waterway dredging construction described in this invention utilizes a disintegrating component. Whenever a penetrating block passes through a drainage hole, multiple scraper rods simultaneously rotate on the surface of the penetrating block, scraping away the surface and causing the silt adhering to it to detach. Furthermore, because the scraper rods are equipped with multiple crushing teeth, these teeth break down the silt while scraping the surface of the penetrating block, effectively removing the silt adhering to the surface of the penetrating block. This prevents the silt from being carried back to the inner wall of the drainage hole when the penetrating block is reset, preventing repeated blockage and ensuring the durability of the dredging effect. Simultaneously, the crushing teeth break down the ejected clumps of silt into small fragments, making them easier to drain with the water flow or fall off naturally, further improving the cleaning effect and operational smoothness.

[0018] 3. The high-efficiency excavation device for waterway dredging construction described in this invention utilizes a sludge-collecting component. When it is necessary to pour the sludge from the bucket body into a container, the bucket body is adjusted to an angle with the opening facing upwards, and the outlet of the sludge discharge pipe is aligned with the container opening. The sludge inside the bucket body will slide down to the middle of the bucket body under the influence of gravity and fall into the sludge discharge pipe. The sludge can then flow into the container through the sludge discharge pipe, avoiding sludge spillage outside the container, which improves collection efficiency and avoids pollution to the construction site environment.

[0019] Furthermore, when the sludge is discharged through the sludge discharge pipe, the sliding rods on both sides slide into the inner cavity of the fixed plate, and the two mud-gathering plates will also move closer to each other, thereby pushing the sludge located in the middle of the bucket body towards the collection port. This allows the sludge to gather at the collection port, and the sludge outside the area of ​​the collection port can also be pushed into the sludge discharge pipe. This cycle is repeated multiple times to ensure that the sludge is accurately and centrally discharged into the designated container, avoiding spillage and waste, and improving collection efficiency and unloading accuracy.

Detailed Implementation

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please refer to Figure 1 , Figure 2 , Figure 7The present invention provides a technical solution: a high-efficiency excavation device for channel dredging construction, including a bucket body 1, a plurality of bucket teeth 7 at one end of the bucket body 1, an installation seat 5 for connecting with an excavator on the bucket body 1, a plurality of drainage holes 2 on the bucket body 1, and an integrated component for scraping mud and dredging on the bucket body 1. The integrated sludge scraping and dredging component includes a scraping shell 20 that can move inside the bucket body 1. Multiple through blocks 21 that match the specifications of the drainage holes 2 are slidably inserted through one side of the scraping shell 20, and adjacent through blocks 21 are fixedly connected by connecting blocks 30. The number of through blocks 21 is the same as the number of drainage holes 2 in a row. When the scraping shell 20 moves inside the bucket body 1, the multiple through blocks 21 are aligned with the multiple rows of drainage holes 2 in sequence, and the through blocks 21 push out the sludge through the drainage holes 2.

[0025] In this embodiment, as Figure 1 , Figure 6 , Figure 7 As shown, the bucket body 1 is equipped with a displacement assembly for driving the scraper shell 20 to move; The displacement assembly includes two transverse frames 9, which are symmetrically slidably arranged on both sides of the bucket body 1. A slider 19 is slidably arranged on the transverse frame 9 along the vertical direction. A rotating plate 6 is rotatably arranged on one side of the slider 19. The scraping shell 20 is fixedly connected to the two rotating plates 6.

[0026] The displacement component also includes a drive structure; The drive structure includes a lead screw 17 threadedly connected to the transverse frame 9. Both ends of the lead screw 17 are rotatably mounted on the bucket body 1. Motors 29 are fixedly mounted on both sides of the bucket body 1. The motors 29 on both sides are fixedly connected to the ends of the two lead screws 17 respectively. A lead screw 16 is threadedly connected to one side of the slider 19. Both ends of the lead screw 16 are rotatably mounted on the transverse frame 9. A motor 28 is fixedly mounted on the transverse frame 9. The output end of the motor 28 is fixedly connected to one end of the lead screw 16. A motor 18 is fixedly mounted on one side of the slider 19. The output end of the motor 18 is fixedly connected to the rotating end of the rotating plate 6.

[0027] An electric push rod 24 is fixedly installed on one side of the inner cavity of the scraping shell 20, and the piston end of the electric push rod 24 is fixedly connected to one side of the through block 21.

[0028] Specifically, the excavator is connected to the mounting base 5, and the excavator moves the bucket body 1 so that the bucket teeth 7 can be inserted into the silt to carry out excavation work.

[0029] During the excavation process, excess water in the silt will flow out through the drainage hole 2, thereby reducing the ineffective load and increasing the amount of silt held.

[0030] Whenever the bucket body 1 unloads material, the excavator adjusts the bucket body 1 to an angle with the opening facing downwards. Then, motors 3 (18), 5 (28), and 6 (29) are started. Motor 3 (18) drives the rotating plate 6 to rotate, thereby adjusting the angle of the scraper shell 20. Motor 5 (28) drives the lead screw 2 (16) to rotate, allowing the slider 19 to slide vertically. Motor 6 (29) drives the lead screw 3 (17) to rotate, allowing the transverse frame 9 to slide horizontally. This allows the scraper shell 20 to move horizontally and vertically. In this way, the scraper shell 20 can adapt to the shape changes of the inner side of the bucket body 1 and move along the inner surface of the bucket body 1, thereby scraping the silt adhering to the inner surface of the bucket body 1, thus promoting the separation of the silt from the inner wall of the bucket body 1.

[0031] After the sludge in the bucket body 1 is emptied, the bucket body 1 is adjusted to an angle with the opening facing upwards. Then, the scraper shell 20 is driven to move along the inner side of the bucket body 1. Multiple through blocks 21 will sequentially align with multiple rows of drainage holes 2. Each time multiple through blocks 21 align with a row of drainage holes 2, the electric actuator 24 drives the through blocks 21 to move, causing multiple through blocks 21 to pass through the drainage holes 2 simultaneously, thus pushing out the sludge and clearing the drainage holes 2. Furthermore, since the bucket body 1 is now facing upwards, the pushed-out sludge will fall naturally and will not return to the drainage holes 2.

[0032] This allows for the effective removal of silt adhering to the inner wall of the bucket body 1 and the walls of the drainage holes 2, through the cooperation of the scraper shell 20 and the through block 21. This solves the problem of reduced bucket body 1 capacity and difficulty in unloading caused by silt adhesion; simultaneously, it avoids the impact of drainage holes 2 blockage on drainage performance. The entire process requires no manual intervention or machine shutdown, ensuring continuous dredging operations, significantly improving excavation efficiency, and reducing energy waste.

[0033] Furthermore, all motors in this embodiment are equipped with independent sealed housings, so even if the bucket body 1 is submerged in water or its surface is covered with silt, it will not affect the normal operation of the motors. These sealed housings are conventional waterproof sealing structures that can be implemented by those skilled in the art, and will not be described in detail here.

[0034] In this embodiment, as Figure 3 and Figure 7 As shown, the scraping shell 20 is also equipped with a dispersing component; The disintegration assembly includes multiple scraper rods 26, each scraper rod 26 is rotatably mounted on a through block 21, the scraper rod 26 is in contact with the surface of the through block 21, and the surface of the scraper rod 26 is provided with multiple breaking teeth 27.

[0035] The rotating end of the scraper 26 is fixedly fitted with a worm gear 25, and a worm 22 is rotatably mounted on the through block 21. The worm 22 has multiple helical teeth, and each helical tooth meshes with a worm gear 25. A motor 23 is fixedly mounted on the through block 21, and the output end of the motor 23 is fixedly connected to one end of the worm 22.

[0036] Specifically, in the above embodiment, although the drain hole 2 can be cleared by the through block 21, when the through block 21 comes into contact with the silt in the drain hole 2, the silt is easy to adhere to the surface of the through block 21. When the through block 21 is reset, the silt on its surface may stick back to the inner wall of the drain hole 2, resulting in repeated blockage of the drain hole 2, which in turn affects the clearing effect.

[0037] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Each time the through block 21 passes through the drain hole 2, the motor 23 drives the worm gear 22 to rotate, which in turn drives multiple worm wheels 25 to rotate simultaneously. This causes multiple scraper rods 26 to rotate on the surface of the through block 21, scraping away the sludge adhering to it. Furthermore, because the scraper rods 26 are equipped with multiple breaking teeth 27, these teeth break up the sludge while scraping the surface of the through block 21, effectively removing the sludge adhering to the surface of the through block 21. This prevents the sludge from being carried back to the inner wall of the drain hole 2 when the through block 21 resets, thus preventing repeated blockages and ensuring the longevity of the unblocking effect. Simultaneously, the breaking teeth 27 break up the ejected clumps of sludge, dispersing them into smaller fragments that are more easily discharged with the water flow or fall off naturally, further improving the cleaning effect and the smoothness of the operation.

[0038] In this embodiment, as Figure 4 , Figure 5 , Figure 8 As shown, the main body 1 of the bucket is equipped with a mud-gathering component; The mud-gathering component includes a gathering port 8 located in the middle of the bucket body 1, the gathering port 8 being connected to a mud discharge pipe 10, a baffle 15 being rotatably installed at the opening of the mud discharge pipe 10, and mud-gathering plates 3 being slidably installed on both sides of the bucket body 1.

[0039] A second motor 14 is fixedly installed on the mud discharge pipe 10, and the output end of the second motor 14 is fixedly connected to one end of the baffle 15.

[0040] A fixed plate 13 is fixedly provided on one side of the bucket body 1. Sliding rods 4 are slidably inserted into both sides of the inner cavity of the fixed plate 13. One end of the sliding rod 4 is fixedly connected to one side of the mud-collecting plate 3.

[0041] A motor 11 is fixedly installed in the middle of the inner cavity of the fixed plate 13. A lead screw 12 is fixedly installed on both sides of the output end of the motor 11. The lead screw 12 on both sides is threadedly connected to the sliding rod 4 on both sides.

[0042] Specifically, in the above embodiments, although the excavator can rotate the bucket body 1 to an angle with the opening facing downwards for unloading, in some cases, it is necessary to collect the sludge into a designated container. For example, when the sludge needs to be unloaded into a mud transport ship, transport vehicle, or a fixed sludge treatment pond on the shore, relying solely on the overall tilting of the bucket body 1 for unloading results in a large unloading range that is difficult to control precisely. This can easily cause the sludge to spill outside the container, leading to reduced collection efficiency and pollution of the construction site environment.

[0043] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When it is necessary to pour the sludge from the bucket body 1 into the container, firstly, the excavator is used to adjust the bucket body 1 so that the opening faces upwards, and the inlet of the sludge discharge pipe 10 is aligned with the container opening. At this time, the sludge inside the bucket body 1 will slide down to the middle of the bucket body 1 under the action of gravity, which is the area where the collection port 8 is located. The sludge will then fall into the sludge discharge pipe 10 accordingly. Subsequently, the motor 14 drives the baffle 15 to rotate, so that the baffle 15 no longer blocks the pipe opening, and the sludge can flow into the container through the sludge discharge pipe 10, avoiding the sludge from spilling outside the container, which helps to improve collection efficiency and avoids pollution to the construction site environment.

[0044] Furthermore, since the bucket body 1 has a certain width, when the sludge flows to the middle of the bucket body 1 under the action of gravity, some of the sludge will be outside the area of ​​the collection port 8, which will cause the sludge to be unable to accurately enter the discharge pipe 10.

[0045] Therefore, in order to solve this problem, the ends of the two mud-gathering plates 3 in the initial state are flush with the side wall of the bucket body 1. When the sludge is discharged through the mud discharge pipe 10, the motor 11 drives the lead screws 12 on both sides to rotate, so that the sliding rods 4 on both sides slide into the inner cavity of the fixed plate 13. Then the two mud-gathering plates 3 will also move closer to each other, thereby pushing the sludge located in the middle of the bucket body 1 towards the gathering port 8, so that the sludge gathers at the gathering port 8, and the sludge outside the area of ​​the gathering port 8 can also be pushed into the mud discharge pipe 10. This cycle is repeated many times to ensure that the sludge is accurately and centrally discharged into the designated container, avoiding spillage and waste, and improving collection efficiency and unloading accuracy.

[0046] In addition, when the sludge flows along the inner wall of the bucket body 1 to the collection port 8, the scraper shell 20 can also scrape the sludge at the same time, which promotes the sludge to flow to the collection port 8, thereby improving the sludge discharge efficiency.

[0047] In addition, both motor 11 and motor 2 14 in this embodiment are sealed and are not affected by water flow and silt.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
