Description

Technical Field

[0001] This utility model belongs to the field of water conservancy construction technology, specifically relating to a silt removal device for water conservancy construction. Background Technology

[0002] In water conservancy construction, grab buckets are frequently used to clean silt. Existing technologies include Chinese utility model patent document CN214141255U, which discloses a silt-cleaning grab bucket; and another Chinese utility model patent document CN220013822U, which discloses a river silt-cleaning device. The clay components in silt easily form a gel-like adsorption, and during the dredging process, the silt readily adheres to the inner wall of the grab bucket. This adhered silt tends to remain on the inner wall of the grab bucket, requiring repeated opening and closing of the grab bucket or manual cleaning during unloading, thus prolonging the single operation cycle. If not cleaned in time, the adhered silt occupies the effective volume of the grab bucket, reducing dredging efficiency.

[0003] Therefore, it is necessary to design a silt cleaning device for water conservancy construction that can automatically clean the silt adhering to the inside of the grab bucket and ensure the efficiency of dredging to solve the current technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a silt cleaning device for water conservancy construction that can automatically clean the silt adhering to the inside of the grab bucket, ensuring dredging efficiency.

[0020] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 3As shown, this utility model provides a silt removal device for water conservancy construction, including a connecting seat 1. Two rotating shafts 11 are symmetrically arranged at both ends of the connecting seat 1. A grab bucket 4 is rotatably mounted on each rotating shaft 11. A hanger 2 is mounted on the top of the connecting seat 1, and a hydraulic cylinder 5 for driving the grab bucket 4 to rotate is mounted on the side of the hanger 2. The grab bucket 4 has an arc-shaped plate 41 coaxial with the rotating shafts 11. Side plates 42 are fixedly mounted at both ends of the arc-shaped plate 41 and are rotatably connected to the rotating shafts 11. An elastic sludge scraping mechanism 6 is fixedly mounted inside the grab bucket 4. The elastic sludge scraping mechanism 6 has scrapers 61 arranged radially along the arc-shaped plate 41, with the edges of the scrapers 61 elastically abutting against the inner wall of the arc-shaped plate 41. When the grab bucket 4 is closed, the scrapers 61 and the upper edges of the arc-shaped plate 41 abut against each other. In this embodiment, the hydraulic cylinder 5 drives the grab bucket 4 to flip or reset, thereby opening or closing the grab bucket 4 to grab or unload sludge. The sludge is grabbed into the grab bucket 4 and then moved to the unloading position. The hydraulic cylinder 5 controls the grab bucket 4 to open. During the opening process, the two grab buckets 4 rotate in opposite directions, while the scraper 61 remains stationary. As the grab bucket 4 moves continuously, the scraper 61 can scrape off the sludge adhering to the inner side of the arc plate 41 and fall down after the grab bucket 4 opens, completing the unloading. During the unloading process, the scraper 61 is fixed, while the grab bucket 4 moves relative to the scraper 61, which can automatically clean the sludge adhering to the inner wall of the arc plate 41 of the grab bucket 4 without manual cleaning, reducing the impact of sludge on the effective volume of the grab bucket and ensuring dredging efficiency.

[0022] The scraper 61 and the arc plate 41 are elastically opposed, which allows the scraper 61 and the inner wall of the arc plate 41 to maintain a moderate tight fit.

[0023] In some embodiments, such as Figure 3 As shown, a slide block 64 is provided above the scraper 61. A slide rod 65 is slidably arranged inside the slide block 64 along the radial direction of the arc plate 41. Support plates 63 are fixed at both ends of the slide rod 65. A flat support rod 7 is fixed at the top of the support plate 63. One end of the flat support rod 7 is fixedly connected to the connecting seat 1. A spring 66 is fitted on the outside of the slide rod 65 between the support plate 63 near the connecting seat 1 and the slide block 64. When the scraper 61 abuts against the inner wall of the arc plate 41, a certain distance is reserved between the support plate 63 away from the connecting seat 1 and the slide block 64. The elastic force of the spring 66 acts on the slide block 64, so that the scraper 61 fixed on the slide block 64 elastically abuts against the inside of the arc plate 41, so that the scraper 61 remains in close contact with the inner wall of the arc plate 41.

[0024] In some embodiments, a scraper support plate 62 is fixedly provided at the bottom of the slide 64, and a scraper 61 is detachably fixedly provided on one side of the scraper support plate 62. After a period of use, the scraper 61 will be worn. The scraper 61 is detachably fixedly connected to the scraper support plate 62, which makes it easy to disassemble and replace the scraper 61. Specifically, the scraper 61 is detachably fixedly provided on one side of the scraper support plate 62 by bolts and nuts.

[0025] In some embodiments, a diagonal support arm 8 is fixedly provided at the top of one end of the flat support rod 7 near the scraper 61, and the end of the diagonal support arm 8 facing away from the flat support rod 7 is fixedly connected to the hanger 2; the flat support rod 7, the diagonal support arm 8 and the hanger 2 form a triangular frame structure, which provides stable support for the scraper 61.

[0026] In some embodiments, a strip 9 is detachably fixed to the bottom edge of the arc plate 41. When grabbing silt, the strip 9 is worn in contact with the ground, which can prevent the arc plate 41 from being worn in contact with the ground. The strip 9 is detachable, which makes it easy to replace it after it is worn. Specifically, the strip 9 is detachably fixed to the bottom edge of the arc plate 41 by bolts.

[0027] In some embodiments, a lower hinge seat 43 is fixedly provided at the center of the top of the arc plate 41, and an upper hinge seat 21 corresponding to the lower hinge seat 43 is provided on the side of the hanger 2. One end of the hydraulic cylinder 5 is hinged to the lower hinge seat 43, and the other end of the hydraulic cylinder 5 is hinged to the upper hinge seat 21.

[0028] In some embodiments, the top of the hanger 2 is hinged to a connecting frame 3.

[0029] The above are preferred embodiments of the present utility model. Those skilled in the art should understand that the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
