Description

Technical Field

[0001] This utility model belongs to the field of river dredging technology, and more specifically, it relates to a device for dredging riverbed sediment. Background Technology

[0002] Riverbed sediments accumulate large amounts of pollutants, such as heavy metals and organic matter. These pollutants not only affect water quality but also damage aquatic ecosystems. Therefore, riverbed sediment dredging equipment is needed to regularly remove sediment from riverbeds. Existing riverbed sediment dredging equipment is mainly mounted on boats or riverbanks, and uses dredging structures such as cutterheads and suction heads to reach deep into the riverbed to extract sediment.

[0003] Existing application number CN202120760746.8 discloses a dredging device for riverbed sediment with good stability, including a base plate, a support column, a sediment storage tank, and a dredging pump respectively arranged on the base plate. The dredging pump is connected to the sediment storage tank. A support plate is arranged on the support column, and an adjustment mechanism or hydraulic rod is arranged on the support plate. A mixing tank is arranged on the adjustment mechanism, and a dredging port is arranged on the mixing tank. A fixing pin is arranged on the support column, and a bearing is sleeved on the fixing pin. A winding roller is sleeved on the bearing, and a conveying pipe is arranged on the winding roller. The two ends of the conveying pipe are connected to the dredging pump and the dredging port respectively. A mixing component is arranged in the mixing tank. This utility model solves the technical problem that existing dredging devices cannot disperse the sediment, which easily causes pipe blockage, resulting in very low sediment extraction efficiency and affecting normal operation. By setting up the mixing component, the sediment sucked into the mixing tank can be stirred and dispersed, which improves the dredging efficiency to a certain extent and avoids pipe blockage.

[0004] Based on the above, existing riverbed sediment dredging equipment, after using dredging cutters and suction heads to extract and clean the sediment, often leaves a large amount of sludge adhering to the surface of these components, along with various debris such as branches and plastic bottles. Currently, most of this is done manually using high-pressure water guns for washing and cleaning, but this process is labor-intensive and prone to causing sludge and debris to splash and pollute the area. Furthermore, suction heads typically pump the sediment directly through pipes to a storage bin for temporary storage before subsequent processing or transportation, but the sediment contains a large amount of water, increasing the difficulty of subsequent processing and the weight of the transported sediment. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a riverbed sediment dredging device. This addresses the shortcomings of existing riverbed sediment dredging devices. After the sediment is extracted and cleaned using dredging cutters, suction heads, and other devices, a large amount of sludge often adheres to the surface of these dredging components, along with various debris such as branches and plastic bottles. Currently, most cleaning relies on manual high-pressure water jets, but this process is labor-intensive and prone to causing sludge and debris to splash and pollute the area. Furthermore, suction heads typically pump the sediment directly through pipes to a storage bin for temporary storage before subsequent processing or transportation. However, the high water content in the sediment increases the difficulty of subsequent processing and the weight required for transportation.

[0006] The purpose and effectiveness of this utility model riverbed dredging device are achieved by the following specific technical means: The riverbed dredging device includes a mounting bracket, a transmission rail, a rail trolley, a sludge suction mechanism, a dredging cutter, a drainer, a flusher, a water filtration assembly, and a flushing assembly; the transmission rail is fixedly installed on the upper part of the mounting bracket; the rail trolley is located inside the transmission rail; the sludge suction mechanism is located inside the rail trolley; the dredging cutter is located at the bottom of the sludge suction mechanism; the drainer is fixedly installed inside the mounting bracket; the flusher is fixedly installed inside the mounting bracket; the water filtration assembly is located inside the drainer; and the flushing assembly is located inside the flusher.

[0007] Furthermore, the water filtration assembly includes an inlet and a drive motor, wherein the inlet is installed inside the drainer; and the drive motor is bolted to the front side of the drainer.

[0008] Furthermore, the water filtration assembly also includes: a conveying auger and a water filtration baffle. The conveying auger is rotatably connected inside the dewatering device, and one end of the conveying auger is installed inside the drive motor. The water filtration baffle is fixedly installed inside the dewatering device, and the water filtration baffle is connected to the feed inlet. The water filtration baffle has an arc structure and fits against the outer arc of the conveying auger.

[0009] Furthermore, the rinsing assembly includes: a double-sided rack, a transmission plate, and a return spring. The double-sided rack is slidably connected inside the rinsing device, and both sides of the double-sided rack are composed of rack structures. The transmission plate is fixedly installed at the top of the double-sided rack. One end of the return spring is fixedly installed inside the rinsing device, and the other end of the return spring is fixedly installed at the end of the double-sided rack.

[0010] Furthermore, the rinsing assembly also includes: a rotating shaft and transmission gears. The rotating shaft is provided in two sets, and the two sets of rotating shafts are rotatably connected inside the rinsing device. The transmission gear is provided in two sets, and the two sets of transmission gears are coaxially fixedly installed in the middle of the two sets of rotating shafts. The two sets of transmission gears are respectively meshed on the left and right sides of the double-sided rack.

[0011] Furthermore, the rinsing assembly also includes: a transmission rod, a semi-circular plate, and a high-pressure nozzle. The transmission rod is provided in two sets, and the two sets of transmission rods are respectively fixedly installed on the top of two sets of rotating shafts. The semi-circular plate is provided in two sets, and the two sets of semi-circular plates are respectively fixedly installed on one end of the two sets of transmission rods. The high-pressure nozzle is provided in multiple sets, and the multiple sets of high-pressure nozzles are fixedly installed on the inner side of the two sets of semi-circular plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Firstly, this utility model has a water filtration component. The conveying auger is driven by a drive motor to transport the sludge that falls into the feed inlet. During the transport process, the conveying auger also squeezes the sludge, causing the water in the sludge to flow out from the water filtration baffle at the bottom of the feed inlet and be discharged to the outside of the drainer. This performs preliminary water filtration on the sludge, effectively reducing the weight of the sludge and facilitating its transportation and subsequent processing.

[0014] Secondly, this invention features a flushing assembly. The squeezing action of the dredging cutter itself causes the transmission plate to shift, which in turn moves the double-sided rack synchronously. This rack drives a series of parts, causing the two sets of semicircular plates to swing in opposite directions until they are fully closed, enveloping the outside of the dredging cutter and providing protection against impacts from external machinery and flying sand. Simultaneously, high-pressure nozzles spray high-pressure water vapor to thoroughly flush and clean the surface of the dredging cutter, significantly improving its cleaning efficiency. Furthermore, the closed semicircular plates effectively prevent impurities removed from the dredging cutter from splashing everywhere.

[0015] This invention has the advantages of being easy to use, safe and protective, and quick to clean. It effectively reduces the weight of silt, facilitates the transportation and subsequent treatment of silt, greatly improves the cleaning efficiency of the sludge auger, and avoids the debris cleaned off the surface of the sludge auger from splashing everywhere.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1:

[0025] As attached Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a riverbed dredging device, including a mounting bracket 1, a transmission rail 2, a rail trolley 3, a sludge suction mechanism 4, a dredging cutter 5, a drainer 6, a flusher 7, and a water filtration assembly; the transmission rail 2 is fixedly installed on the upper part of the mounting bracket 1; the rail trolley 3 is located inside the transmission rail 2; the sludge suction mechanism 4 is located inside the rail trolley 3; the sludge suction cutter 5 is located at the bottom of the sludge suction mechanism 4; the drainer 6 is fixedly installed inside the mounting bracket 1; the flusher 7 is fixedly installed inside the mounting bracket 1; and the water filtration assembly is located inside the drainer 6.

[0027] The water filtration assembly includes an inlet 601 and a drive motor 602. The inlet 601 is installed inside the drainer 6, and the drive motor 602 is bolted to the front of the drainer 6.

[0028] The water filtration assembly also includes: a conveying auger 603 and a water filtration baffle 604. The conveying auger 603 is rotatably connected inside the drainer 6, and one end of the conveying auger 603 is installed inside the drive motor 602. The water filtration baffle 604 is fixedly installed inside the drainer 6 and is connected to the feed inlet 601. The water filtration baffle 604 has an arc structure and fits against the outer arc of the conveying auger 603.

[0029] The specific usage and function of this embodiment: The track trolley 3 can drive the sludge suction mechanism 4 to move within the transmission track 2, thereby adjusting the sludge suction mechanism 4 to a suitable position. The track trolley 3, with its internal mechanical structure, can also realize the lifting and lowering of the sludge suction mechanism 4, enabling the sludge suction mechanism 4 to work in conjunction with the dredging cutter 5 to carry out dredging work on the bottom of the river. The bottom sludge sucked up by the sludge suction mechanism 4 is transported through a pipeline to the feed inlet 601. At this time, the drive motor 602 drives the conveying auger 603 to operate, conveying the sludge falling into the feed inlet 601. During the process of the conveying auger 603 squeezing and conveying the sludge, the water in the sludge flows out from the filter baffle 604 at the bottom of the feed inlet 601 and is discharged to the outside of the drainer 6. The sludge that has undergone preliminary drainage is then transported by the conveying auger 603 to the storage bin outside the drainer 6 for temporary storage, facilitating subsequent centralized processing. In this example, the movement of the railcar 3, its operation of lifting and lowering the suction mechanism 4, and the specific process of the suction mechanism 4 and the dredging cutter 5 carrying out dredging operations are all mature technologies already existing in this field. Therefore, for the sake of brevity, they will not be elaborated upon here. Example 2:

[0030] Based on Example 1, such as Figures 1 to 6 As shown, it also includes a rinsing assembly, which is disposed inside the rinsing unit 7.

[0031] The rinsing assembly includes a double-sided rack 701, a transmission plate 7011, and a return spring 7012. The double-sided rack 701 is slidably connected inside the rinsing device 7, and both sides of the double-sided rack 701 are composed of rack structures. The transmission plate 7011 is fixedly installed at the top of the double-sided rack 701. One end of the return spring 7012 is fixedly installed inside the rinsing device 7, and the other end of the return spring 7012 is fixedly installed at the end of the double-sided rack 701.

[0032] The rinsing assembly also includes: a rotating shaft 702 and a transmission gear 7021. Two sets of rotating shafts 702 are provided, and the two sets of rotating shafts 702 are rotatably connected inside the rinsing device 7. Two sets of transmission gears 7021 are provided, and the two sets of transmission gears 7021 are coaxially fixedly installed in the middle of the two sets of rotating shafts 702. The two sets of transmission gears 7021 are respectively meshed on the left and right sides of the double-sided rack 701.

[0033] The rinsing assembly also includes: a transmission rod 7022, a semi-circular plate 703, and a high-pressure nozzle 7031. Two sets of transmission rods 7022 are provided, and the two sets of transmission rods 7022 are respectively fixedly installed on the top of two sets of rotating shafts 702; two sets of semi-circular plates 703 are provided, and the two sets of semi-circular plates 703 are respectively fixedly installed on one end of the two sets of transmission rods 7022; multiple sets of high-pressure nozzles 7031 are provided, and multiple sets of high-pressure nozzles 7031 are fixedly installed on the inner side of the two sets of semi-circular plates 703.

[0034] The specific usage and function of this embodiment: After the dredging operation is completed, the track trolley 3 is immediately started, driving the sludge suction mechanism 4 and the dredging cutter 5 to move towards the mounting bracket 1, ready for storage. When the dredging cutter 5 reaches the position of the transmission plate 7011, its own squeezing action causes the transmission plate 7011 to shift, thereby driving the double-sided rack 701 to move synchronously. During this process, the return spring 7012 is compressed, accumulating elastic potential energy. As the double-sided rack 701 moves, the two sets of transmission gears 7021 meshing with it begin to rotate relative to each other. These two sets of transmission gears 7021 are respectively connected to two sets of rotating shafts 702, and the rotation of the gears drives the rotating shafts 702 to rotate synchronously. The rotation of the rotating shafts 702 then drives the two sets of transmission rods 7022 to swing at a specific angle, ultimately causing the two sets of semicircular plates 703 to swing in opposite directions until they are completely closed, wrapping the outside of the dredging cutter 5 and achieving a protective function. Simultaneously, the high-pressure nozzle 7031 mounted on the semi-circular plate 703 begins operation, spraying high-pressure water vapor to thoroughly clean the surface of the dredging cutter 5. The closed semi-circular plate 703 also effectively prevents impurities removed from the surface of the dredging cutter 5 from splashing everywhere, maintaining a clean working environment. In this embodiment, the high-pressure nozzle 7031 spraying water utilizes existing technology and will not be described in detail here.
