Description

Technical Field

[0001] This utility model relates to the technical field of waterway silt removal equipment, specifically a silt removal device used for waterway dredging. Background Technology

[0002] Silt removal during waterway improvement is a crucial step in ensuring navigation capacity and maintaining the aquatic ecosystem. Long-term silt accumulation can lead to shallower waterways, deteriorated navigation conditions, and even water pollution. Silt removal ensures safe navigation. Silt buildup can reduce waterway depth, increasing the risk of ship grounding and impacting shipping efficiency and safety. Furthermore, silt may contain heavy metals, organic matter, and other pollutants, which can release harmful substances in anaerobic environments, causing eutrophication and water quality deterioration. Removal reduces ecological risks and improves the aquatic ecosystem. Excessive silt in rivers and waterways reduces flood discharge capacity, increasing the risk of flooding during the rainy season. Removal enhances water flow capacity and improves flood control and drainage capabilities. Therefore, silt removal must balance navigation needs, ecological protection, and cost-effectiveness.

[0003] Existing methods for silt removal mostly involve grab dredgers, chain bucket dredgers, and hydraulic dredging. Grab dredgers and chain bucket dredgers typically break up the silt with a cutter head and then pump it out using a mud pump. Hydraulic dredging uses high-pressure water jets to disperse the silt, which is then pumped out again. While both methods can remove silt, hydraulic dredging relies heavily on manpower, requires a large water supply, and has low operational efficiency. Grab dredgers and chain bucket dredgers are expensive to operate, and their use is limited by the need to maintain a certain water level in the river channel. Therefore, we propose a silt removal device for waterway dredging to address these issues. Utility Model Content

[0026] 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.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a silt removal device for waterway dredging, including a tracked vehicle 1, a loading frame 2 installed at one end of the tracked vehicle 1, the tracked vehicle 1 is remote controlled, and the tracked vehicle 1 is remote controlled by staff on the shore to control the movement position of the tracked vehicle 1 and the angle of the bucket 10.

[0028] Two swing arms 3 are hinged to the outer surface of the loading frame 2, and the two swing arms 3 are symmetrical. A hydraulic cylinder 4 is installed above the swing arms 3. A collection bucket 5 is connected to the inner wall of the swing arms 3. A drain hole 6 is opened on the inner side of the collection bucket 5. An auger 7 is rotatably connected to the inner wall of the collection bucket 5. A motor 8 is installed at one end of the collection bucket 5. The output shaft of the motor 8 is connected to one end of the auger 7. The hydraulic cylinder 4 is used as the power source to drive the swing arms 3 to swing. While the swing arms 3 are swinging, they rotate to drive the bucket 10 to adjust the angle. The motor 8 is used as the power source to provide power for the rotation of the auger 7. After the auger 7 rotates, it pushes the sludge inside the collection bucket 5 to move its position, providing power for the sludge to flow into the conveying pipe 16.

[0029] A rotating cylinder 9 is rotatably connected to the outer surface of the collection bucket 5. Multiple buckets 10 are connected to the outer surface of the rotating cylinder 9 and are arranged in a circular array. The rotating cylinder 9 rotates to move the buckets 10 and removes the silt as they move. When the buckets 10 are in a high position, the silt inside the buckets 10 slides down and passes through the through holes 11. The silt then passes through the through holes 11 and through the drain holes 6 and falls into the collection bucket 5. The inner side of the rotating cylinder 9 has the same number of through holes 11 as the buckets 10 and is arranged in a circular array.

[0030] A sprocket 12 is connected to the outer surface of the rotating drum 9. A motor 2 13 is installed on one side of the swing arm 3. The output shaft of the motor 2 13 is connected to a sprocket 2 14. A toothed chain 15 is sleeved on the outside of the sprocket 2 and the sprocket 12 and the sprocket 2 14 are connected by a transmission through the toothed chain 15. The motor 2 13 is the power source to provide power for the rotation of the rotating drum 9. The motor 2 13 outputs power through the sprocket 2 14. The rotating drum 9 receives power through the sprocket 12 and transmits the power of the sprocket 2 14 to the sprocket 12 through the toothed chain 15, thereby driving the rotating drum 9 to rotate.

[0031] The other end of the collection bucket 5 is connected to a conveying pipe 16, which is made of rubber. A collection box 17 is installed on the top of the tracked vehicle 1. The other end of the conveying pipe 16 is connected to one side of the collection box 17. The sludge collected by the collection bucket 5 is transported through the conveying pipe 16 and temporarily stored through the collection box 17. The rubber conveying pipe 16 is used to adjust the position and change the angle of the collection bucket 5. A discharge hole 18 is opened on the inner side of the collection bucket 5 and is connected to the conveying pipe 16. The sludge inside the collection bucket 5 flows into the conveying pipe 16 through the discharge hole 18.

[0032] A support seat 19 is connected to one side of the loading frame 2, and a first ear seat 20 is connected to one side of the support seat 19. The fixed end of the hydraulic cylinder 4 is hinged to the inner wall of the first ear seat 20. A second ear seat 21 is connected to the outer surface of the swing arm 3. The output end of the hydraulic cylinder 4 is hinged to the inner wall of the second ear seat 21. The support seat 19 and the first ear seat 20 provide support force for the hydraulic cylinder 4 to maintain the stability of the hydraulic cylinder 4. The swing arm 3 receives the power of the hydraulic cylinder 4 through the second ear seat 21 and provides power for the swing arm 3 to swing through the hydraulic cylinder 4. The swing arm 3 swings to adjust the digging depth of the bucket 10.

[0033] Both swing arms 3 have outriggers 22 connected to their outer surfaces. A support plate 23 is connected to one side of each outrigger 22. The outriggers 22 provide support to the support plate 23, maintaining its stability. Multiple nozzles 24 are installed on the inner side of the support plate 23, and the nozzles 24 are arranged in an equidistant array. The input ends of the nozzles 24 are connected to a water supply pipe 25, which is supplied with water through an external pipe. The water supply pipe 25 distributes the water to the nozzles 24, which then spray the water. The sprayed water is located in front of the bucket 10. The water sprayed by the nozzles 24 cuts and wets the silt, making it easier for the bucket 10 to dig up the silt and preventing the silt from drying out too much and flowing into the collection bucket 5.

[0034] A mud pump 26 is installed inside the collection box 17. The output end of the mud pump 26 is located outside the collection box 17. After the collection box 17 is full, the mud pump 26 discharges the sludge inside to prevent the sludge from overflowing to the outside. A pipe is connected to the output end of the mud pump 26 to transport the sludge to the outside transfer vehicle.

[0035] Working principle: When in use, first control the tracked vehicle 1 to enter the riverbed, start motor 8 and motor 13. After motor 8 starts, it drives the auger 7 to rotate. After motor 13 starts, it drives the rotating drum 9 to rotate through the toothed chain 15. Then, the hydraulic cylinder 4 pushes the swing arm 3 to move its position. After the swing arm 3 moves its position, it controls the bucket 10 to contact the silt through the rotating drum 9 to dig out the silt. After the bucket 10 digs out the silt, it rotates upward. After the through hole 11 aligns with the drain hole 6, the silt falls into the collection bucket 5. The auger 7 pushes the silt to move its position. Then, the silt enters the collection box 17 through the conveying pipe 16.
