Description

Technical Field

[0001] This utility model belongs to the technical field of sand dredging devices, specifically a chain bucket sand dredging device. Background Technology

[0002] The chain bucket dredging device is a sand dredging equipment used in river channels, ports and other scenarios. It consists of multiple sets of chain buckets connected into a ring chain, which is driven by a drive device to circulate. After the chain buckets scoop up mud and sand underwater, they are lifted to the discharge end for discharge. The device is mainly composed of a bucket bridge, chain buckets, drive system, hydraulic adjustment mechanism, etc. The tilt angle of the bucket bridge can be adjusted by the hydraulic system to adapt to different water depths and sand layer conditions. It has the characteristics of continuous operation, high efficiency and strong adaptability.

[0003] The existing chain bucket dredging devices have the following shortcomings: the existing chain bucket dredging devices lack the function of adjusting the bucket angle. The buckets of the existing chain bucket dredging devices are directly installed on the bucket chain. When the tilt angle of the bucket bridge is adjusted to adapt to different water depths, the opening face of the bucket also tilts accordingly, which directly leads to a reduction in the amount of mud and sand loaded and a significant reduction in operating efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a chain bucket sand dredging device, which solves the problem that existing chain bucket sand dredging devices lack the function of adjusting the bucket angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chain bucket sand dredging device, comprising a mounting plate, a pair of mounting blocks fixedly connected to one side of the mounting plate, a connecting block rotatably connected to the mounting plate, a bucket fixedly connected to one side of the connecting block, a pair of mounting brackets I fixedly connected to the bottom of the bucket, a rotating block rotatably connected to each mounting bracket I, a pair of fixing components provided on the rotating block, a flange ring I fixedly connected to the rotating block, a pair of mounting brackets II fixedly connected to the side of the mounting plate away from the mounting blocks, a rotating seat rotatably connected to each mounting bracket II, a hydraulic cylinder fixedly connected to one side of the rotating seat, a protective component provided on the hydraulic cylinder, and a flange ring II fixedly connected to the hydraulic cylinder.

[0006] As a further embodiment of this utility model: the fixing component includes a bracket, which is fixedly connected to the rotating block. A screw is threadedly connected to the bracket. A knob is coaxially fixedly connected to one end of the screw, and a pin is rotatably connected to the other end of the screw. One end of the pin passes through the rotating block and is slidably connected to it.

[0007] As a further embodiment of this utility model: the protective component includes a bellows, which is sleeved on the outer periphery of the hydraulic cylinder. Both ends of the bellows are fixedly connected to connecting rings, and a flange ring is fixedly connected to the side of the connecting ring away from the bellows.

[0008] As a further embodiment of this utility model: a pair of insertion holes are provided on the output end of the hydraulic cylinder, and each insertion hole is adapted to a corresponding pin.

[0009] As a further embodiment of this utility model: a circular groove is provided on the rotating block, and the circular groove is adapted to the output end of the hydraulic cylinder.

[0010] As a further embodiment of this utility model: the first flange ring is connected to the third flange ring by bolts, and the second flange ring is connected to the third flange ring by bolts.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-6 As shown, this utility model provides a technical solution:

[0023] A chain bucket sand dredging device includes a mounting plate 1. A pair of mounting blocks 2 are fixedly connected to one side of the mounting plate 1. A connecting block 3 is rotatably connected to the mounting plate 1. A bucket 4 is fixedly connected to one side of the connecting block 3. A pair of mounting frames 5 are fixedly connected to the bottom of the bucket 4. A rotating block 6 is rotatably connected to each mounting frame 5. A pair of fixing components are provided on the rotating block 6. A flange ring 7 is fixedly connected to the rotating block 6. A pair of mounting frames 8 are fixedly connected to the side of the mounting plate 1 away from the mounting blocks 2. A rotating seat 9 is rotatably connected to each mounting frame 8. A hydraulic cylinder 10 is fixedly connected to one side of the rotating seat 9. A protective component is provided on the hydraulic cylinder 10. A flange ring 11 is fixedly connected to the hydraulic cylinder 10. Mounting plate 1 is connected to bucket chain via mounting block 2. The output end of hydraulic cylinder 10 is connected to rotating block 6 via fixed component. When hydraulic cylinder 10 is started, the output end of hydraulic cylinder 10 drives rotating block 6 to move. Rotating block 6 drives bucket 4 to move via mounting frame 5. Bucket 4 rotates on mounting plate 1 via connecting block 3, thereby realizing the adjustment of bucket 4 angle, so that the opening surface of bucket 4 always remains horizontal. No matter how the bucket bridge is tilted, bucket 4 can maintain maximum effective volume when scooping sand, ensuring work efficiency. The protective component can cover the output end of hydraulic cylinder 10, which can prevent mud, sand and sewage in sand dredging operations from entering the interior of hydraulic cylinder 10, avoid particle wear on seals, and reduce the risk of oil leakage.

[0024] The fixing assembly includes a bracket 12, which is fixedly connected to the rotating block 6. A screw 13 is threaded onto the bracket 12. A knob 14 is coaxially fixedly connected to one end of the screw 13, and a pin 15 is rotatably connected to the other end of the screw 13. One end of the pin 15 passes through the rotating block 6 and is slidably connected. A pair of insertion holes are provided on the output end of the hydraulic cylinder 10, and each insertion hole is adapted to the corresponding pin 15. A circular groove is provided on the rotating block 6, which is adapted to the output end of the hydraulic cylinder 10. The output end of the hydraulic cylinder 10 falls into the circular groove on the rotating block 6, and the pin 15 is inserted into the corresponding insertion hole on the output end of the hydraulic cylinder 10, so that the output end of the hydraulic cylinder 10 and the rotating block 6 are connected together. By rotating the screw 13 by the knob 14, the pin 15 can be pulled out from the insertion hole, separating the output end of the hydraulic cylinder 10 and the rotating block 6.

[0025] The protective assembly includes a bellows 16, which is sleeved around the outer periphery of the hydraulic cylinder 10. Both ends of the bellows 16 are fixedly connected to connecting rings 17. A flange ring 3 18 is fixedly connected to the side of the connecting ring 17 away from the bellows 16. Flange ring 1 7 and the corresponding flange ring 3 18 are connected by bolts, and flange ring 2 11 and the corresponding flange ring 3 18 are also connected by bolts. The bellows 16 dynamically seals as it expands and contracts with the output end of the hydraulic cylinder 10. The connecting ring 17 can block the knob 14 to prevent the screw 13 from loosening. By unscrewing the bolts, flange ring 1 7 and the corresponding flange ring 3 18 can be separated, as can flange ring 2 11 and the corresponding flange ring 3 18. After the rotating block 6 is separated from the output end of the hydraulic cylinder 10, the bellows 16, connecting ring 17, and flange ring 3 18 can be removed and replaced.

[0026] The working principle of this utility model is as follows:

[0027] Mounting plate 1 is connected to bucket chain via mounting block 2. The output end of hydraulic cylinder 10 falls into the circular groove on rotating block 6. Pin 15 is inserted into the corresponding insertion hole on the output end of hydraulic cylinder 10, so that the output end of hydraulic cylinder 10 and rotating block 6 are connected together. When hydraulic cylinder 10 is started, the output end of hydraulic cylinder 10 drives rotating block 6 to move. Rotating block 6 drives bucket 4 to move via mounting bracket 5. Bucket 4 rotates on mounting plate 1 via connecting block 3, thereby realizing the adjustment of bucket 4 angle, so that the opening surface of bucket 4 always remains horizontal. No matter how the bucket bridge is tilted, bucket 4 can maintain the maximum effective volume when scooping sand, ensuring work efficiency. Bellows 16 dynamically seals as the output end of hydraulic cylinder 10 extends and retracts, which can prevent mud, sand and sewage in sand scooping operations from entering the interior of hydraulic cylinder 10, avoid particle wear on seals, and reduce the risk of oil leakage.

[0028] First, by unscrewing the bolts, flange ring 17 can be separated from the corresponding flange ring 3 18, and flange ring 2 11 can be separated from the corresponding flange ring 3 18. Then, by turning screw 13 with knob 14, pin 15 can be pulled out from the insertion hole, separating the output end of hydraulic cylinder 10 from rotating block 6, so that bellows 16, connecting ring 17 and flange ring 3 18 can be removed and replaced.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
