Description

Technical Field

[0001] This utility model relates to the field of grab bucket equipment technology, specifically a grab bucket equipment for cleaning silt from water conservancy channels. Background Technology

[0002] Silt dredging grabs are key pieces of equipment in water conservancy projects used to remove silt deposited at the bottom of channels. They typically consist of two or more opening and closing flaps, which grab, lift, and unload the silt through opening and closing motions. These devices are widely used in the maintenance of irrigation channels, drainage ditches, and rivers, effectively restoring the channel's cross-sectional area and ensuring smooth water flow. Grab buckets are generally driven by steel cables or hydraulic systems and used in conjunction with lifting machinery such as cranes or specialized dredging vessels. Their working principle is similar to a robotic arm; by closing the flaps, they cut into the silt layer, clamp the silt, and lift it to the ground or into a transport device, completing the dredging task.

[0003] However, the fixed size of some existing silt-clearing grab buckets leads to limitations in practical applications. When the grab bucket is designed to be large, although the efficiency of a single operation is high, it occupies a lot of space during equipment storage or transportation, which is not conducive to operation and storage management in narrow spaces. On the other hand, if a small grab bucket is used, although it is easy to store and operate flexibly, the limited amount that can be grabbed at a time requires repeated grabbing operations to complete the same silt-clearing task, which significantly reduces the overall work efficiency and increases energy consumption and mechanical wear. Therefore, we propose a grab bucket device for silt clearing in water conservancy channels. Utility Model Content

[0004] The purpose of this utility model is to provide a grab bucket device for cleaning silt from water conservancy channels, so as to solve the problem mentioned in the background art that some existing grab buckets have large storage and transportation space requirements due to their fixed size, and it is difficult to balance operation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grab bucket device for cleaning silt from water conservancy channels, comprising: a main shaft;

[0006] It also includes: two grab bucket assemblies, which are located at the lower part of the main shaft. The grab bucket assemblies are used to grab sludge. Each grab bucket assembly includes a first bucket body, which has symmetrically opened grooves. Each groove cavity is slidably connected to an extension bucket body. A second bucket body is fixedly connected to the side of the extension bucket body away from the first bucket body.

[0007] An adjustment assembly is installed between the main shaft and the grab bucket assembly, and is used to connect the two grab bucket assemblies;

[0008] The drive component is located in the middle of the adjustment component and is used to drive the two grab bucket components to expand and close.

[0009] The main shaft has two symmetrically rotating support plates on both sides. A second connecting plate is rotatably connected to the side of the support plate away from the main shaft. The second connecting plate is fixedly connected to the side of the inner wall of the adjacent first bucket near the main shaft.

[0010] The drive assembly includes a first connecting block fixedly connected to the main shaft. An electric push rod is provided on the side of the first connecting block near the grab assembly. A connecting rod is fixedly connected to the output end of the piston rod of the electric push rod. A first connecting plate is symmetrically fixedly connected to the connecting rod.

[0011] The adjustment component includes a second connecting block that is fixedly connected to the side of the two first connecting plates away from the first connecting block. A sliding shaft is symmetrically slidably connected to the middle of the second connecting block. A first docking block is rotatably connected to the side of the two sliding shafts that are far from each other. A second docking block is rotatably connected to the side of the sliding shafts that are close to the first docking block. The first docking block is fixedly connected to the inner wall of the adjacent second hopper. The second docking block is fixedly connected to the inner wall of the other adjacent second hopper.

[0012] The sliding shaft has several first limiting holes in the middle of the side away from the first docking block, and the second connecting block has an observation port on the side close to the first docking block. The sliding shaft has several indicator grooves on the side close to the observation port, and the positions of the several first limiting holes correspond to the positions of the several indicator grooves.

[0013] The second connecting block is threaded with a first bolt on the side near the observation port. The first bolt is slidably connected to the inner cavity of the adjacent first limiting hole. The first bolt is threaded with a first nut on the side near the grab bucket assembly.

[0014] The first bucket body is threaded with several second bolts, and the extended bucket body has several second limiting holes on the side near the second bolts. The second bolts are slidably connected to the adjacent second limiting holes, and a second nut is threaded on one side of each second bolt.

[0015] This utility model has at least the following beneficial effects:

[0016] The grab bucket assembly consists of a first bucket body and a second bucket body, making the entire grab bucket compact in its closed state, facilitating storage and transportation. During operation, by adjusting the position of the extension bucket body within the chute cavity and then adjusting the distance between the first and second bucket bodies, an expandable grabbing space can be created within the grab bucket assembly. This allows the extension bucket body to slide along the chute and expand to the required width, increasing the grabbing area and improving the efficiency of a single dredging operation. This resolves the contradiction between space utilization and operational efficiency in traditional fixed-size grab buckets, enhancing the practicality and versatility of the grab bucket.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a grab bucket device for cleaning silt in water conservancy channels, comprising: a main shaft 1;

[0027] It also includes: two grab bucket assemblies 5, which are located at the lower part of the main shaft 1. The grab bucket assembly 5 is used to grab silt. The grab bucket assembly 5 includes a first bucket body 51, which has symmetrically opened grooves 511. The inner cavity of each groove 511 is slidably connected to an extension bucket body 52. ​​The side of the extension bucket body 52 away from the first bucket body 51 is fixedly connected to a second bucket body 521.

[0028] Adjustment component 3 is located between the main shaft 1 and the grab bucket assembly 5. Adjustment component 3 is used to connect the two grab bucket assemblies 5.

[0029] Drive component 2 is located in the middle of adjustment component 3. Drive component 2 is used to drive the two grab bucket components 5 to expand and close.

[0030] The grab bucket assembly 5 consists of a first bucket body 51 and a second bucket body 521, making the entire grab bucket compact in its closed state, facilitating storage and transportation. During operation, by adjusting the position of the extension bucket body 52 in the inner cavity of the slide groove 511 and then adjusting the distance between the first bucket body 51 and the second bucket body 521, an expandable grabbing space can be formed in the grab bucket assembly 5. This allows the extension bucket body 52 to slide along the slide groove 511 and expand to the required width, increasing the grabbing area and improving the efficiency of single dredging. This solves the contradiction between space utilization and operational efficiency in traditional fixed-size grab buckets, improving the practicality and versatility of the grab bucket.

[0031] The adjusting assembly 3 includes a second connecting block 31 fixedly connected to the side of the two first connecting plates 24 away from the first connecting block 21. A sliding shaft 32 is symmetrically slidably connected to the middle of the second connecting block 31. A first docking block 33 is rotatably connected to the side of the two sliding shafts 32 away from each other. A second docking block 34 is rotatably connected to the side of the sliding shaft 32 close to the first docking block 33. The first docking block 33 is fixedly connected to the inner wall of the adjacent second hopper 521. The second docking block 34 is fixedly connected to the inner wall of the other adjacent second hopper 521. A plurality of first limiting holes 321 are provided in the middle of the side of the sliding shaft 32 away from the first docking block 33. An observation port 311 is provided on the side of the second connecting block 31 close to the first docking block 33. A plurality of indicator grooves 322 are provided on the side of the sliding shaft 32 close to the observation port 311. The positions of the plurality of first limiting holes 321 correspond to the positions of the plurality of indicator grooves 322 respectively.

[0032] The second connecting block 31 is threaded with a first bolt 35 on the side near the observation port 311. The first bolt 35 is slidably connected to the inner cavity of the adjacent first limiting hole 321. The first bolt 35 is threaded with a first nut 36 on the side near the grab bucket assembly 5. The first bucket body 51 is threaded with several second bolts 512. The extension bucket body 52 is provided with several second limiting holes 522 on the side near the second bolts 512. The second bolts 512 are slidably connected to the adjacent second limiting holes 522. A second nut 513 is threaded on one side of each second bolt 512.

[0033] When adjusting the size of the grab bucket, firstly, the position of the sliding shaft 32 within the inner cavity of the second connecting block 31 needs to be determined. Then, by rotating the first nut 36, the first bolt 35 is separated from the first nut 36. Next, the first bolt 35 is separated from the inner cavity of the adjacent first limiting hole 321, releasing the position restriction of the sliding shaft 32 within the inner cavity of the first limiting hole 321. Then, by rotating the second nut 513, the second bolt 512 is separated from the second nut 513. Finally, the second bolt 512 is separated from the inner cavity of the adjacent second limiting hole 321. Separating within the cavity of the positioning hole 522 releases the positional constraint on the extension bucket 52 within the cavity of the slide groove 511. Then, by applying force to the second bucket 521, it slides away from the first bucket 51, allowing the extension bucket 52 to slide within the cavity of the slide groove 511. Since the first docking block 33 and the second docking block 34 are fixedly connected to the inner walls of adjacent second buckets 521, the movement of the second bucket 521 will cause the first docking block 33 and the second docking block 34 to move together. Since both the first docking block 33 and the second docking block 34 are rotatably connected to the sliding shaft 32, and limit rings are provided on both sides of the first docking block 33 and the second docking block 34, the sliding shaft 32 can be driven to slide in the inner cavity of the second connecting block 31 when the first docking block 33 and the second docking block 34 move. After the size adjustment of the grab bucket is completed, by inserting the first bolt 35 into the inner cavity of the adjacent first limit hole 321, and then through the cooperation of the first nut 36 and the first bolt 35, the sliding shaft 32 can be moved in the inner cavity of the second connecting block 31. The position within the inner cavity is defined by an observation port 311, which allows the user to observe the position of the indicator groove 322 and determine the position of the first limiting hole 321. This facilitates the insertion of the first bolt 35 into the inner cavity of the first limiting hole 321. Then, the second bolt 512 is inserted into the adjacent second limiting hole 522. Finally, the second nut 513, in conjunction with the second bolt 512, defines the position of the extended bucket 52 within the inner cavity of the slide groove 511, thereby completing the adjustment of the grab bucket size.

[0034] Example 2

[0035] Two support plates 4 are symmetrically rotatably connected to both sides of the main shaft 1. A second connecting plate 41 is rotatably connected to the side of the support plate 4 away from the main shaft 1. The second connecting plate 41 is fixedly connected to the inner wall of the adjacent first bucket 51 near the main shaft 1. The drive assembly 2 includes a first connecting block 21 fixedly connected to the main shaft 1. An electric push rod 22 is provided on the side of the first connecting block 21 near the grab bucket assembly 5. A connecting rod 23 is fixedly connected to the piston rod output end of the electric push rod 22. A first connecting plate 24 is symmetrically fixedly connected to the connecting rod 23.

[0036] When using the grab bucket, the grab bucket is connected to the excavator, and then the electric push rod 22 is controlled to operate. The piston rod of the electric push rod 22 drives the connecting rod 23 and the first connecting plate 24 to slide towards one side of the grab bucket assembly 5. This causes the second connecting block 31 to slide towards one side of the grab bucket assembly 5. The second connecting block 31 applies a downward force to the first docking block 33 and the second docking block 34, causing the two grab bucket assemblies 5 to unfold. Since the second connecting plate 41 is fixedly connected to the inner wall of the adjacent first bucket body 51, it can rotate around the support plate 4. Then, the piston rod of the electric push rod 22 drives the connecting rod 23 and the first connecting plate 24 to slide away from the grab bucket assembly 5. This causes the second connecting block 31 to slide away from the grab bucket assembly 5. The second connecting block 31 applies an upward force to the first docking block 33 and the second docking block 34, causing the two grab bucket assemblies 5 to close, thus completing the grabbing of silt.
