Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dredging mechanisms, specifically a dredging structure for a wharf. Background Technology
[0002] Dock dredging refers to the cleaning of waterways near docks to remove sediment, silt, and other impurities, ensuring unobstructed navigation and access to the docks. This work is crucial for ensuring the safe berthing of ships, the loading and unloading of cargo, and maintaining the overall operational efficiency of the port.
[0003] In existing technologies, dock dredging typically involves setting up mechanisms such as sludge collection tanks, sedimentation tanks, sewage tanks, active devices, driven devices, and suction devices. To improve suction efficiency and prevent poor suction, a filter screen is installed at the inlet of the vertical pipe to filter large pieces of debris. However, because dock sludge contains plastic waste or leaves and other impurities, these easily clog the filter screen, making it difficult for sludge to enter the vertical pipe and affecting the sludge cleaning effect. This necessitates repeated manual cleaning of the filter screen, significantly increasing workload. Furthermore, after the sludge is initially collected in the sludge collection tank, it needs to be manually or pumped to transfer the sludge to the container for the next process. Manual transfer is labor-intensive, and pump discharge is time-consuming, reducing dredging efficiency. Therefore, this utility model proposes a dredging structure for docks to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a dredging structure for wharves to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dredging structure for a wharf, comprising a trolley, a tilting frame rotatably mounted on the trolley, a sludge collection bucket fixedly mounted on the tilting frame, a support frame on one side of the sludge collection bucket, an upper hydraulic cylinder fixedly mounted at the lower end of the support frame, the output end of the upper hydraulic cylinder facing downward and having an mounting cylinder, a crushing blade holder rotatably mounted inside the mounting cylinder, a collection cylinder at the upper end of the crushing blade holder, a spiral blade rotatably mounted inside the collection cylinder, a sludge pump at the upper end of the support frame, the input end of the sludge pump being connected to the collection cylinder via a pipe, and the output end of the sludge pump being connected to the sludge collection bucket via a pipe.
[0006] Preferably, a lower hydraulic cylinder is provided on both sides of the sludge collection tank. One end of the lower hydraulic cylinder is rotatably connected to the trolley via a connecting pin, and the other end of the lower hydraulic cylinder is rotatably connected to the middle of the lower connecting rod via a connecting pin. One end of the lower connecting rod is rotatably connected to the trolley via a connecting pin, and the other end of the lower connecting rod is rotatably connected to the tilting frame via a connecting pin. An upper connecting rod is provided on the upper side of the lower connecting rod. One end of the upper connecting rod is rotatably connected to the trolley via a connecting pin, and the other end of the upper connecting rod is rotatably connected to the tilting frame via a connecting pin.
[0007] Preferably, a drive control box is installed at the upper end of the support frame, and the sewage pump, upper hydraulic cylinder, and lower hydraulic cylinder are all electrically connected to the drive control box.
[0008] Preferably, a fixing frame is fixedly connected to the upper surface of the mounting cylinder, a motor is fixedly mounted on the upper surface of the fixing frame, the output end of the motor passes through the fixing frame and is fixedly connected to one end of the connecting shaft, the other end of the connecting shaft is fixedly connected to the spiral blade, and the output end of the upper hydraulic cylinder is fixedly connected to the fixing frame.
[0009] Preferably, a drive gear is fixedly sleeved on the connecting shaft, a driven gear meshes around the drive gear, a limit shaft is fixed inside the driven gear, the crushing blade holder is fixedly sleeved on the limit shaft, and both the connecting shaft and the limit shaft are rotatably connected to the fixed frame.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the device is moved to the dockside by a trolley. The inlet of the sludge pump is connected to the collection cylinder via a pipeline, and the outlet of the sludge pump is connected to the sludge collection tank. Then, the upper hydraulic cylinder is activated, causing it to insert the installation cylinder into the dock silt. The sludge pump is then activated to suck up the silt. Simultaneously, the rotating shredder cutter head cuts and breaks up the silt sucked into the installation cylinder, thereby crushing large pieces of garbage and foreign objects in the silt, thus avoiding the need for collection... The blockage of the cylinder leads to poor subsequent sludge discharge. The rotation of the spiral blades collects the sludge, which then enters the collection cylinder. Finally, the sludge is connected to the pipeline and sucked into the sludge collection tank by the sludge pump. When the sludge collection tank is full, the tilting frame rotates, causing the sludge collection tank to tilt away from the support frame, thereby dumping the sludge into the container for the next process. This avoids the trouble of manual operation and the time-consuming pump suction, ensuring that the entire structure can continuously dredge. As a result, it is very flexible and convenient to use, meets different usage needs, and has a wider range of applications. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0016] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a dredging structure for a wharf, including a trolley 2, a tilting frame 3 rotatably mounted on the trolley 2, a sludge collection bucket 4 fixedly mounted on the tilting frame 3, a support frame 5 on one side of the sludge collection bucket 4, an upper hydraulic cylinder 6 fixedly mounted at the lower end of the support frame 5, the output end of the upper hydraulic cylinder 6 facing downward and having an installation cylinder 7, a crushing blade holder 8 rotatably mounted inside the installation cylinder 7, a collection cylinder 9 at the upper end of the crushing blade holder 8, and a spiral blade 1 rotatably mounted inside the collection cylinder 9.
[0017] The support frame 5 is welded and fixed to one side of the trolley 2, thereby ensuring the stability of the installation cylinder 7. First, the device is moved to the dockside by the trolley 2. The input end of the sludge pump 14 is connected to the collection cylinder 9 through a pipeline connection, and the output end of the sludge pump 14 is connected to the sludge collection tank 4. Then, the upper hydraulic cylinder 6 is started, which drives the installation cylinder 7 to be inserted into the sludge at the dock. Then, the sludge pump 14 is started to suck up the sludge. At the same time, the rotation of the crushing blade holder 8 cuts the sludge sucked into the installation cylinder 7. The system breaks down the sludge, crushing large pieces of garbage and foreign objects in the sludge to prevent blockage of the collection cylinder 9 and subsequent sludge discharge. The sludge is then collected by the rotation of the spiral blade 1 and enters the collection cylinder 9. Finally, the sludge is drawn into the sludge collection tank 4 through the pipeline connection and the suction pump 14. When the sludge collection tank 4 is full, it is tilted by the tilting frame 3 to pour the sludge into the container for the next process. This avoids the trouble of manual operation and the time-consuming pump suction, ensuring that the entire structure can continuously clean up sludge.
[0018] Example 2: Based on Example 1, a lower hydraulic cylinder 11 is provided on both sides of the sludge collection tank 4. One end of the lower hydraulic cylinder 11 is rotatably connected to the trolley 2 via a connecting pin, and the other end of the lower hydraulic cylinder 11 is rotatably connected to the middle of the lower connecting rod 12 via a connecting pin. The lower hydraulic cylinder 11 is provided on both sides of the trolley 2. The non-output end of the lower hydraulic cylinder 11 is rotatably connected to the side of the trolley 2 via a connecting pin, and the output end of the lower hydraulic cylinder 11 is rotatably connected to the middle of the lower connecting rod 12 via a connecting pin. One end of the lower connecting rod 12 is rotatably connected to the trolley 2 via a connecting pin, and the other end of the lower connecting rod 12 is rotatably connected to the tilting frame 3 via a connecting pin. An upper connecting rod 13 is provided on the upper side of the lower connecting rod 12. One end of the upper connecting rod 13 is rotatably connected to the trolley 2 via a connecting pin, and the other end of the upper connecting rod 13 is rotatably connected to the tilting frame 3 via a connecting pin.
[0019] Once the sludge collection tank 4 is full, the output end of the lower hydraulic cylinder 11 is extended by the drive control box 15, which pushes the lower connecting rod 12 to move. The two ends of the lower connecting rod 12 are connected to the trolley 2 and the tilting frame 3 respectively through connecting pins, so that the lower connecting rod 12 gradually becomes horizontal. At the same time, the tilting frame 3 is rotated away from the support frame 5. As the tilting frame 3 rotates, the upper connecting rod 13 and the connecting pin rotate to make the sludge collection tank 4 tilt downward, thereby dumping the sludge into the container of the next process. This avoids the trouble of manual transfer, reduces labor intensity, improves sludge removal efficiency, and ensures the continuous sludge removal effect of the device.
[0020] Example 3: Based on Example 2, the trolley 2 is fixedly connected to one end of the support frame 5, and the lower surface of the other end of the support frame 5 is fixedly connected to the upper hydraulic cylinder 6. A sludge pump 14 and a drive control box 15 are installed on the upper side of the upper hydraulic cylinder 6. One end of the support frame 5 is welded and fixed to the top of one side of the trolley 2. Four upper hydraulic cylinders 6 are fixedly installed on the lower surface of the other end of the support frame 5 to provide stable support for the upper hydraulic cylinders 6. The output end of the upper hydraulic cylinder 6 is fixedly connected to the upper surface of the fixed frame 16. The sludge pump 14 and the drive control box 15 are both fixedly installed on the support frame 5. The sludge pump 14, the upper hydraulic cylinder 6, and the lower hydraulic cylinder 11 are all electrically connected to the drive control box 15. A fixed frame 16 is fixedly connected to the upper surface of the mounting cylinder 7. A motor 17 is fixedly installed on the upper surface of the fixed frame 16. The output end of the motor 17 passes through the fixed frame 16 and is fixedly connected to one end of the connecting shaft 18. The other end of the connecting shaft 18 is connected to the screw... The top of the rotor blade 1 is fixedly connected, and the output end of the upper hydraulic cylinder 6 is fixedly connected to the fixed frame 16. The connecting shaft 18 is rotatably sleeved in the mounting cylinder 7 and one end is fixedly connected to the top of the rotor blade 1. The middle of the connecting shaft 18 is fixedly sleeved with a drive gear 19. The drive gear 19 is meshed with driven gears 20 around its perimeter. The driven gear 20 is fixedly sleeved with a limiting shaft 21. The crushing blade holder 8 is fixedly sleeved on the limiting shaft 21. The collecting cylinder 9 is fixedly sleeved in the mounting cylinder 7. The connecting shaft 18 and the limiting shaft 21 are both rotatably sleeved in the fixed frame 16, the mounting cylinder 7, and the collecting cylinder 9. The drive gear 19 and the driven gear 20 are both embedded and rotatably mounted on the top of the mounting cylinder 7. The driven gear 20 is fixedly sleeved with a limiting shaft 21. The limiting shaft 21 is rotatably sleeved between the mounting cylinder 7 and the fixed frame 16, thereby limiting the limiting shaft 21 through the mounting cylinder 7 and the fixed frame 16, thus ensuring the stability of the rotation of the limiting shaft 21.
[0021] The input end of the sludge pump 14 is connected to the collection cylinder 9 via a pipeline connection, and the output end of the sludge pump 14 is connected to the sludge collection bucket 4. The upper hydraulic cylinder 6 is extended and retracted by the drive control box 15, which allows for easy adjustment of the position and height of the sludge removal mechanism, facilitating the cleaning of sludge in different locations. This makes it highly flexible and convenient to use, meeting various application needs and broadening its scope of application. The upper hydraulic cylinder 6 drives the installation cylinder 7 to be inserted into the sludge at the dock. At this time, the motor 17 is started, which drives the connecting shaft 18 to rotate, thereby causing the connecting shaft 18 to rotate the spiral blade 1. The rotation of the spiral blade 1 facilitates the collection of sludge. Simultaneously, the rotation of the connecting shaft 18... The drive gear 19 rotates, and the drive gear 19 meshes with the driven gear 20, which in turn drives the limit shaft 21 to rotate. Under the rotation of the limit shaft 21, the crusher 8 rotates. The crusher 8 can cut and disperse the sludge in the suction cylinder 7, thereby crushing large pieces of garbage or foreign objects in the sludge. The crushed sludge can then smoothly enter the collection cylinder 9 along the spiral blade 1. It then enters the collection tank 4 through the connection of the collection cylinder 9, the sludge pump 14, and the sludge collection tank 4, thereby cleaning the sludge and simultaneously crushing and extracting the sludge to avoid problems with poor sludge discharge, thus ensuring the continuous sludge removal effect of the entire device.
