Description

Technical Field

[0001] This utility model relates to the technical field of dredging devices, specifically a mobile dredging device for water conservancy projects. Background Technology

[0002] An amphibious excavator is a heavy-duty machine specifically designed for operating in both water and land environments. It combines the functionality of a traditional excavator with the ability to travel on water, making it widely applicable in various working conditions such as river and wetland engineering, coastal construction, and flood control projects. The amphibious excavator's track system provides excellent traction in mud and water, ensuring stability in complex terrain.

[0003] After prolonged use, a small amount of sludge accumulates inside the bucket of an amphibious excavator. Due to the stickiness of the sludge, and its tendency to solidify over time, it adheres firmly to the inner wall of the bucket, making it difficult to clean. Traditional buckets lack an automatic sludge-washing mechanism, leading to increasing sludge buildup, reduced bucket capacity, and decreased excavation efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a mobile water conservancy engineering dredging device.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A mobile water conservancy engineering dredging device of this utility model includes an amphibious excavator, one end of which is connected to a bucket; two symmetrically arranged water storage boxes are fixedly installed near the bucket of the amphibious excavator; an electric push rod is fixedly installed on one side of the amphibious excavator; a rectangular frame is fixedly installed at the output end of the electric push rod; a rectangular block is installed inside the rectangular frame; a water pump is installed inside the water storage box; the water outlet of the water pump is connected to a water spray pipe; the water spray pipe passes through the rectangular block; and the end of the water spray pipe away from the water storage box faces the bucket.

[0006] Furthermore, a servo motor is fixedly installed inside the rectangular frame, and a lead screw is fixedly installed at the output end of the servo motor. The rectangular block and the lead screw are movably connected.

[0007] Furthermore, the end of the water spray pipe away from the water storage box is rotatably connected to an end cap via a torsion spring, and a rubber sealing ring is fixedly installed on the side of the end cap near the water spray pipe.

[0008] Furthermore, a corrugated pipe is fixedly installed between the rectangular frame and the electric push rod.

[0009] Furthermore, four telescopic components are provided within the rectangular frame. The four telescopic components are arranged in pairs symmetrically around the central axis of the rectangular frame. The telescopic components are fixedly installed between the rectangular frame and the rectangular blocks. The telescopic components are composed of several hollow plates that are slidably connected. An elastic cloth is fixedly installed between two rectangular blocks.

[0010] Furthermore, the hollow plate inside the telescopic assembly is a sealed sliding connection, and a vent pipe is fixedly installed between the telescopic assembly and the tail of the servo motor.

[0011] The advantages of this utility model are:

[0012] 1. This utility model utilizes a water pump within a water storage tank to spray water from the tank through a spray pipe, rinsing the inside of the bucket. As the water flows through the spray pipe, it pushes open the end cover, allowing the water to exit. Due to the limited diameter of the spray pipe's end, it can only reach specific areas. At this point, a servo motor within a rectangular frame is activated, causing a lead screw to move the rectangular block. Since the spray pipe passes through the rectangular block, its movement carries the spray pipe along with it, continuously altering the spray position and achieving comprehensive rinsing of the bucket's interior. This designed mechanism enables rapid rinsing of the bucket, while continuous displacement ensures all-around cleaning, preventing the cleaning of only one area and efficiently removing residual silt, thus maintaining high loading efficiency. When the spray pipe is not in use, the end cover automatically closes via a torsion spring, preventing impurities from entering and ensuring unobstructed flow.

[0013] 2. This utility model protects the output end of the electric push rod by installing a corrugated pipe, reducing the amount of silt and other impurities that may fall onto the output end and affect its sliding. Simultaneously, the installation of an elastic cloth between the two rectangular blocks and the telescopic component inside the rectangular frame both facilitate the movement of the rectangular blocks and reduce the amount of silt entering the rectangular frame during amphibious excavator operation. When the rectangular blocks move, the telescopic component slides, contracts, and extends in sync with them, keeping the rectangular frame closed. Furthermore, the telescopic component compresses the internal gas during sliding and contraction, allowing the gas to enter the servo motor through the vent pipe, thereby cooling the servo motor and enabling it to maintain high efficiency for extended periods.

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-6As shown, a mobile water conservancy engineering dredging device includes an amphibious excavator 1, with a bucket 2 connected to one end of the amphibious excavator 1. Two symmetrically arranged water storage boxes 3 are fixedly installed on the amphibious excavator 1 near the bucket 2. An electric push rod 4 is fixedly installed on one side of the amphibious excavator 1. A rectangular frame 5 is fixedly installed at the output end of the electric push rod 4. A rectangular block 6 is installed inside the rectangular frame 5. A water pump is installed inside the water storage box 3, and the outlet of the water pump is connected to a spray pipe 7. The spray pipe 7 passes through the rectangular block 6, with the end of the spray pipe 7 away from the water storage box 3 facing the bucket 2. A servo motor 8 is fixedly installed inside the rectangular frame 5, and a lead screw 9 is fixedly installed at the output end of the servo motor 8. The rectangular block 6 and the lead screw 9 are movably connected. An end cap 10 is rotatably connected to the end of the spray pipe 7 away from the water storage box 3 via a torsion spring. A rubber sealing ring is fixedly installed on the side of the end cap 10 near the spray pipe 7.

[0024] During operation, after the amphibious excavator 1 completes the silt removal work in the river channel, a large amount of residual silt will remain in its bucket 2. At this time, the water pump in the water storage box 3 is activated, and the water in the water storage box 3 is sprayed through the water spray pipe 7 to flush the inside of the bucket 2. When the water flows out through the water spray pipe 7, it will push open the end cover 10, allowing the water to spray out. Since the diameter of the end of the water spray pipe 7 is limited, it can only flush the corresponding part. At this time, the servo motor 8 in the rectangular frame 5 is activated, and the servo motor 8 moves the rectangular block 6 through the lead screw 9. Since the water spray pipe 7 passes through the rectangular block 6, the rectangular block 6 moves along with the water spray pipe 7, thus continuously moving the water spray pipe 7, thereby changing the spray position and achieving all-round flushing of the inside of the bucket 2. The mechanism designed above enables rapid washing of the bucket 2. Simultaneously, continuous displacement allows for comprehensive washing of the bucket 2, avoiding the limitation of washing only one part. This efficiently removes residual sludge from the bucket 2, ensuring it maintains high loading efficiency. When the water spray pipe 7 is not in use, the end cap 10 automatically closes via a torsion spring, protecting the inside of the water spray pipe 7 from impurities and ensuring its unobstructed flow.

[0025] A corrugated pipe 13 is fixedly installed between the rectangular frame 5 and the electric push rod 4. Four telescopic components 11 are installed inside the rectangular frame 5, arranged symmetrically in pairs around the central axis of the rectangular frame 5. The telescopic components 11 are fixedly installed between the rectangular frame 5 and the rectangular blocks 6. Each telescopic component 11 is composed of several hollow plates that slide together. An elastic cloth 12 is fixedly installed between two rectangular blocks 6. The hollow plates inside the telescopic components 11 are sealed and slide together. A vent pipe 14 is fixedly installed between the telescopic components 11 and the tail of the servo motor 8.

[0026] During operation, the corrugated pipe 13 protects the output end of the electric push rod 4, reducing the amount of silt and other impurities that may fall onto it and affect its sliding. Simultaneously, the elastic cloth 12 installed between the two rectangular blocks 6 and the telescopic component 11 installed inside the rectangular frame 5 both facilitate the movement of the rectangular blocks 6 and reduce the amount of silt entering the rectangular frame 5 during operation of the amphibious excavator 1. When the rectangular blocks 6 move, the telescopic component 11 slides, contracts, and stretches in sync with them, keeping the rectangular frame 5 closed. Furthermore, the telescopic component 11 compresses the internal gas during sliding and contraction, allowing the gas to enter the servo motor 8 through the vent pipe 14, thereby cooling the servo motor 8 which operates for extended periods, enabling it to maintain high efficiency for longer periods.

[0027] Working principle: After the amphibious excavator 1 completes the silt removal work in the river channel, a large amount of residual silt will remain in its bucket 2. At this time, the water pump in the water storage box 3 is activated, and the water in the water storage box 3 is sprayed through the water spray pipe 7 to flush the inside of the bucket 2. When the water flows out through the water spray pipe 7, it will push open the end cover 10, allowing the water to spray out. The servo motor 8 in the rectangular frame 5 is activated, and the servo motor 8 moves the rectangular block 6 through the lead screw 9. Since the water spray pipe 7 passes through the rectangular block 6, the rectangular block 6 moves along with the water spray pipe 7, thus continuously moving the water spray pipe 7 and changing the spray position to achieve all-round flushing of the inside of the bucket 2.

[0028] The corrugated pipe 13 protects the output end of the electric push rod 4, reducing the amount of silt and other impurities that could affect its sliding. Meanwhile, the elastic cloth 12 installed between the two rectangular blocks 6 and the telescopic component 11 installed inside the rectangular frame 5 both facilitate the movement of the rectangular blocks 6 and reduce the amount of silt entering the rectangular frame 5 during operation of the amphibious excavator 1. When the rectangular blocks 6 move, the telescopic component 11 slides, contracts, and stretches in sync with them, keeping the rectangular frame 5 closed. Furthermore, the telescopic component 11 compresses the internal gas during sliding and contraction, allowing the gas to enter the servo motor 8 through the vent pipe 14.
