Description

Technical Field

[0001] This invention relates to an ecological dredging device for river sediment, belonging to the technical field of river dredging equipment. Background Technology

[0002] The deposition of sediment in river channels is a serious hidden danger to river safety. Therefore, in river management, dredging is particularly important. In addition to restoring the river to its basic functions such as flood control, drainage and water diversion, dredging can also promote the restoration of the river aquatic ecosystem and build a healthy, complete and stable river aquatic ecosystem.

[0003] Currently, the main methods used in river management are as follows:

[0004] The first method involves using a sludge pump to pump the mixture of silt and river water to both banks, drain the water, and return it to the river channel. The silt is then transported to a dumping point for unified treatment. However, in actual construction, the high output power of the sludge pump can cause the suction to pull in smaller fish and shrimp. Operationally, because it is necessary to ensure the normal intake of silt, it cannot effectively intercept fish and shrimp, thus causing some damage to the river's ecosystem.

[0005] The second method involves using submerged mechanical equipment to turn over and break up the silt deposited at the bottom of the river, and then transporting it to the riverbank using a conveyor system. However, this method has several drawbacks in actual construction and operation. Due to the complexity of the underwater mechanical components, it is difficult to ensure that the power output equipment (such as diesel engines and worm gear motors) can effectively transmit power to the various underwater mechanical devices. Furthermore, controlling their extension and submersion postures in the water is also quite difficult. These issues make it challenging to ensure the efficient implementation of river dredging work.

Detailed Implementation

[0055] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This invention provides an ecological dredging device for river sediment, which is mounted on an engineering vessel and submerged in the river to clean up sediment. The engineering vessel is equipped with a power output device. The dredging device includes a treatment base 1, a fish and shrimp protection component, a mud-water separation component, and a sludge discharge component.

[0058] The front side of the processing base 1 is connected to the scraper head 11, the processing base 1 has a processing cavity 12 inside, and the processing base 1 also has an interception through hole 13. The interception through hole 13 and the processing cavity 12 are in a connected state.

[0059] The fish and shrimp protection component is installed in the processing chamber 12. The fish and shrimp protection component transfers the fish and shrimp in front of the processing base 1 to the rear of the processing base 1. The power input end of the fish and shrimp protection component is connected to the power output device.

[0060] The mud-water separation component is installed in the processing chamber 12. The mud-water separation component will separate the silt and river water sucked into the processing chamber 12, and the separated river water will be discharged from the bottom of the shovel head 11.

[0061] One end of the sludge discharge assembly is connected to the engineering vessel, and the other end is connected to the treatment base 1. The sludge discharge assembly discharges the sludge separated by the mud-water separation assembly. The power input end of the sludge discharge assembly is connected to the power output device.

[0062] In this embodiment, when the engineering vessel is traveling in the river, it can control the operation of the sludge discharge assembly to lower the treatment base 1 and sink it to the bottom of the river. During the process of the engineering vessel towing the treatment base 1 by the sludge discharge assembly, the shovel head 11 in front of the treatment base 1 can shovel up the silt deposited at the bottom, and then enter the treatment chamber 12 through the interception through hole 13. The mud-water separation assembly therein separates the silt from the river water. Under the action of the mud-water separation assembly, the river water is discharged from the front side of the shovel head 11 to flush the shoveled silt, thereby improving the efficiency of the shovel head 11 in turning over the silt. The separated silt can be discharged to both banks of the river through the sludge discharge assembly.

[0063] Among them, the interception through hole 13 can prevent fish and shrimp from entering the treatment chamber 12 while ensuring that the shoveled silt can enter the treatment chamber 12 normally. The fish and shrimp protection component, driven by the sludge discharge component, can drive away the passing fish and shrimp, thereby improving the ecological environment protection effect of the river during the dredging of river silt.

[0064] The sludge discharge assembly, while ensuring the traction of the treatment base 1 and its assembled components, can discharge the collected sludge. It can also effectively transmit the power of the power output equipment mounted on the engineering vessel to the treatment base 1, thereby driving the fish and shrimp protection assembly to operate effectively. The coordinated operation of the treatment base 1 and its mud-water separation assembly can quickly shovel and collect the sludge at the bottom of the river, effectively improving the efficiency of river dredging.

[0065] Support Figure 1 , Figure 2 and Figure 6 To ensure that the shovel head 11 can effectively scoop up the silt deposited in the river channel, and that the scooped silt moves backward along the shovel head 11 and the treatment base 1 under the action of the moving treatment base 1, and finally enters the treatment chamber 12 through the interception through hole 13, in one embodiment of the river channel silt ecological dredging equipment, a first guide slope is provided on the front side of the treatment base 1, and a second guide slope is provided on the front side of the shovel head 11; an arc-shaped transition surface is provided between the first guide slope and the second guide slope; and shovel teeth 111 are connected to the bottom front side of the shovel head 11.

[0066] Specifically, the design of the shovel teeth 111 ensures that the shovel head 11 can effectively scoop up the silt deposited in the river channel, ensuring the subsequent treatment of the silt. The coordinated arrangement of the first guide slope, the second guide slope, and the arc-shaped transition surface ensures that the scooped silt flows along the front side of the shovel head 11 and the treatment base 1, and then, under the negative pressure generated by the operation of the mud-water separation component, it is pumped into the treatment chamber 12 along with the river water for further treatment.

[0067] Support Figure 1 , Figure 2 , Figure 6 and Figure 7 To ensure that the mud-water separation component can pump the shoveled silt and river water into the treatment chamber 12 together, and to ensure that the mud-water separation component can effectively separate the silt and river water mixture pumped into the treatment chamber 12, in one embodiment of the river sediment ecological dredging equipment, the mud-water separation component includes a filter baffle 31 and a submersible pump 32; the filter baffle 31 is fixedly installed in the treatment chamber 12, and the filter baffle 31 separates the treatment chamber 12 into a water storage chamber 14; the filter baffle 31 blocks the silt in the treatment chamber 12, and the river water in the treatment chamber 12 is introduced into the water storage chamber 14 through the filter baffle 31; the submersible pump 32 is fixedly installed in the water storage chamber 14.

[0068] Specifically, when the submersible pump 32 is running, it can pump the river water above the filter baffle 31 into the water storage chamber 14 below the treatment chamber 12. At the same time, the filter baffle 31 intercepts the silt above the filter baffle 31. In this state, the negative pressure generated by the pumping of the river water in the water storage chamber 14 will cause the silt and river water mixture shoveled up from the outside of the treatment base 1 to be pumped into the treatment chamber 12 through the interception hole 13, continuously inputting the silt to be cleaned into the treatment chamber 12. At the same time, the interception hole 13 isolates the passing fish and shrimp from the outside.

[0069] The river water pumped into the water storage chamber 14 is eventually output from the front of the shovel head 11. The output river water washes away the deposited silt, which can improve the effect of the shovel teeth 111 on the shovel head 11 in shoveling up the silt and ensure the cleaning efficiency of the silt.

[0070] Support Figure 6 To ensure that the river water collected in the water storage chamber 14 is effectively output from the front side of the shovel head 11 by means of the submersible pump 32, in one embodiment of the river silt ecological dredging equipment, the mud-water separation component also includes a drainage nozzle 331, a drainage branch pipe 332, and a drainage main pipe 333; the outlet end of the drainage nozzle 331 is connected to the bottom of the shovel head 11, and the drainage nozzle 331 and the shovel teeth 111 are distributed alternately; the drainage branch pipe 332 is arranged inside the treatment base 1, the drainage nozzle 331 is connected to the outlet end of the drainage branch pipe 332, the downstream end of the drainage main pipe 333 is connected to the inlet end of the drainage branch pipe 332, and the upstream end of the drainage main pipe 333 is connected to the outlet of the submersible pump 32.

[0071] Specifically, the river water pumped by the submersible pump 32 can be discharged through the main drainage pipe 333 and the branch drainage pipe 332, ensuring that the water storage chamber 14 is in a continuous negative pressure state. The discharged river water is finally sprayed by the drainage nozzle 331 onto the front side of the shovel head 11 to flush the deposited silt, making it easier for the shovel teeth 111 to reach into the bottom of the silt and scoop it up, thus improving the silt cleaning efficiency. At the same time, it ensures that the intercepted silt can be effectively collected at the bottom of the treatment chamber 12 and discharged externally with the help of the sludge discharge assembly.

[0072] The filter baffle 31 is designed as a slope, and the sludge intercepted above the filter baffle 31 can be deposited down the slope to the bottom of the treatment chamber 12, so that the sludge can be discharged by means of the sludge discharge assembly.

[0073] Support Figure 1 and Figure 2 To ensure the effective connection between the sludge removal assembly and the engineering vessel and treatment base 1, and to allow the engineering vessel to tow the treatment base 1 and the assembled components within the treatment base 1 effectively in the river channel, the sludge removal assembly can adjust its arrangement to adapt to dredging operations at different depths. Simultaneously, the sludge removal assembly can control the overall lifting and lowering of the treatment base 1 and its assembled components. In one embodiment of the river channel silt ecological dredging equipment, the sludge removal assembly includes a transfer mechanism. This transfer mechanism includes a mounting base 411, a transverse transmission cylinder 412, a longitudinal transmission cylinder 413, a transfer transmission cylinder 414, and a hydraulic telescopic cylinder 415. 411 is connected to the stern of the engineering vessel. The transverse transfer cylinder 412 is fixed to the upper end of the mounting base 411, and the longitudinal transfer cylinder 413 is fixed to the upper end of the processing base 1. The bottom of the longitudinal transfer cylinder 413 extends into the interior of the processing chamber 12. The transfer cylinder 414 is connected between the transverse transfer cylinder 412 and the longitudinal transfer cylinder 413 through a flexible bellows 417. One end of the transfer cylinder 414 is hinged to the mounting base 411, and the other end of the transfer cylinder 414 is hinged to the processing base 1. The fixed end of the hydraulic telescopic cylinder 415 is hinged to the mounting base 411, and the driving end of the hydraulic telescopic cylinder 415 is hinged to the transfer cylinder 414.

[0074] Specifically, the mounting base plate 411 can be assembled to the stern of the engineering vessel by means of bolt fixing or snap-fit ​​connection to ensure effective connection between the sludge discharge component and the engineering vessel. Then, the engineering vessel drives the sludge discharge component and the treatment base 1 to move in the river. With the cooperation of the shovel head 11, the fish and shrimp protection component, the mud-water separation component and the sludge discharge component, the deposited silt is cleaned and transported ashore.

[0075] The transverse transfer cylinder 412, longitudinal transfer cylinder 413, and transfer cylinder 414, which adopt a three-section design, are combined with each other by hinges, which can improve the overall degree of freedom and ensure that the engineering vessel can tow the treatment base 1, which has been sunk to the bottom of the river, forward stably. The transfer cylinder is hinged to the treatment base 1, which can ensure that the treatment base 1 is effectively attached to the bottom of the river, thereby effectively shoveling up the silt deposited at the bottom of the river.

[0076] The hydraulic telescopic cylinder 415 can adjust the angle between the transverse transmission cylinder 412 and the transfer transmission cylinder 414, thereby controlling the raising or lowering posture of the processing base 1. When the hydraulic telescopic cylinder 415 retracts, the angle between the transverse transmission cylinder 412 and the transfer transmission cylinder 414 decreases, and the processing base 1 will sink as a whole. When the hydraulic telescopic cylinder 415 extends, the angle between the transverse transmission cylinder 412 and the transfer transmission cylinder 414 increases and gradually approaches 180°, which can raise the processing base 1 above the river surface.

[0077] Support Figure 1 and Figure 2 The sludge discharge port 416 is provided at the downstream end of the transverse conveying cylinder 412. The sludge conveyed in the sludge discharge assembly is finally discharged from the sludge discharge port 416. The sludge is then transferred to the riverbanks via a sludge conveying pipe at the sludge discharge port 416. This allows the collected sludge to be directly transported to the riverbanks. Since the sludge contains a large proportion of water, the water in the sludge placed on the riverbanks will flow back into the river due to gravity during the settling process. The remaining sludge will be processed in a unified manner.

[0078] Support Figure 5 and Figure 6 To ensure that the sludge discharge assembly can effectively discharge the sludge collected in the treatment chamber 12, and at the same time ensure that the power output device can effectively transmit power to the fish and shrimp protection assembly, in one embodiment of the river sludge ecological dredging equipment, the sludge discharge assembly includes a transmission mechanism, which includes a first mounting shaft 421, a second mounting shaft 422, a third mounting shaft 423, a first spiral conveyor blade 424, a second spiral conveyor blade 425, and a third spiral conveyor blade 426; the first mounting shaft 421 and the first spiral conveyor blade 424 are both located in the transverse transmission cylinder 412, and the first spiral conveyor blade 424 and the first mounting shaft 421 is connected; the second mounting shaft 422 and the second spiral conveyor blade 425 are both in the longitudinal transmission cylinder 413, and the second spiral conveyor blade 425 is connected to the second mounting shaft 422; the third mounting shaft 423 and the third spiral conveyor blade 426 are both in the transfer transmission cylinder 414, and the third spiral conveyor blade 426 is connected to the third mounting shaft 423; the first mounting shaft 421 and the third mounting shaft 423, and the second mounting shaft 422 and the third mounting shaft 423 are all connected by universal couplings 427; the power input end of the first mounting shaft 421 is connected to the power output equipment installed on the engineering vessel.

[0079] Specifically, the power output device is usually a gas turbine or drive motor mounted on the engineering vessel. Its output shaft is connected to the first mounting shaft 421 via a dedicated coupling. When the controller is running, due to the arrangement of the universal coupling 427, the power can be stably transmitted along the first mounting shaft 421, the second mounting shaft 422, and the third mounting shaft 423, thereby driving the first spiral conveyor blade 424, the second spiral conveyor blade 425, and the third spiral conveyor blade 426 to operate effectively. The first spiral conveyor blade 424 is in close contact with the inner wall of the transverse transmission cylinder 412, the second spiral conveyor blade 425 is in close contact with the inner wall of the longitudinal transmission cylinder 413, and the third spiral conveyor blade 426 is in close contact with the inner wall of the transfer transmission cylinder 414. When each spiral conveyor blade is running, it can drive the sludge collected in the treatment chamber 12 to be transmitted along the longitudinal transmission cylinder 413, the transfer transmission cylinder 414, and the flexible corrugated pipe 417 to the transverse transmission cylinder 412, and then discharged from the sludge discharge port 416.

[0080] Support Figure 6 To ensure that the silt collected in the treatment chamber 12 can effectively accumulate at the bottom of the longitudinal transmission cylinder 413, and to ensure that the sludge discharge assembly can effectively discharge the silt from the treatment chamber 12, in one embodiment of the river silt ecological dredging equipment, the sludge discharge assembly further includes a flow guiding mechanism. The flow guiding mechanism includes a fourth mounting shaft 431, a fourth spiral conveying blade 432, and a drive shaft 433. The fourth mounting shaft 431 is located in the treatment chamber 12. Two sets of fourth spiral conveying blades 432 are provided, and the spiral directions of the two sets of fourth spiral conveying blades 432 are opposite. Rotary conveyor blades 432 are arranged on both sides of the longitudinal transmission cylinder 413; a transmission cavity 15 is also provided in the processing base 1, which is arranged below the processing cavity 12. The bottom end of the second mounting shaft 422 extends into the transmission cavity 15, and a first bevel gear 434 is fixedly connected to the bottom of the second mounting shaft 422; the transmission shaft 433 is located in the transmission cavity 15, and a second bevel gear 435 that meshes with the first bevel gear 434 is provided on the transmission shaft 433; the ends of the transmission shaft 433 and the fourth mounting shaft 431 are driven by the first transmission sprocket 436 and the first transmission chain.

[0081] Specifically, when the second mounting shaft 422 drives the first bevel gear 434 to rotate, it can drive the second bevel gear 435 and the transmission shaft 433 fixed to the second bevel gear 435 to drive the transmission stably. Then, through the combination of the first transmission sprocket 436 and the matching first transmission chain, it drives the fourth mounting shaft 431 to rotate stably, thereby making the two sets of fourth spiral conveying blades 432 mounted on the fourth mounting shaft 431 rotate stably.

[0082] The combination of the treatment chamber 12 and the filter baffle 31 forms an arc structure at the bottom of the treatment chamber 12. The fourth mounting shaft 431 is arranged at the arc structure, and the fourth spiral conveying blade 432 is in close contact with the arc structure. When the two sets of fourth spiral conveying blades 432 rotate, they can drive the silt that is evenly distributed in the arc structure to move towards the longitudinal transmission cylinder 413 at the center, so that the longitudinal transmission cylinder 413 can effectively receive the silt and transfer it to both banks of the river through the guide mechanism and the transmission mechanism.

[0083] Support Figure 8 and Figure 9 During equipment operation, the continuous action of the submersible pump 32 will generate a continuous negative pressure inside the treatment chamber 12. To prevent fish and shrimp from being sucked into the interception hole 13 due to the negative pressure, thus causing their death and affecting the river ecology, and to prevent fish and shrimp from clogging the interception hole 13 and making it difficult for silt to be properly sucked into the treatment chamber 12, thus affecting the dredging efficiency, a fish and shrimp protection component is provided. In one embodiment of the river silt ecological dredging equipment, the fish and shrimp protection component includes an active roller 21, a driven roller 22, a synchronous pulley 23, a synchronous belt 24, and a fish and shrimp chuck 25; a strip-shaped passage connecting to the outside is opened on the front side of the treatment chamber 12. Hole 16; the ends of the drive roller 21 and the drive shaft 433 are driven by the second drive sprocket 437 and the second drive chain; the drive roller 21 and the driven roller 22 are both installed inside the processing chamber 12, and the drive roller 21 and the driven roller 22 are both fixedly installed with synchronous pulleys 23 arranged inside the strip-shaped through hole 16; the synchronous belt 24 runs on the synchronous pulleys 23 on the drive roller 21 and the driven roller 22; fish and shrimp tweezers 25 are evenly connected to the outer side of the synchronous belt 24, and the fish and shrimp tweezers 25 extend out of the outside of the strip-shaped through hole 16; the fish and shrimp protection component transfers the fish and shrimp in front of the processing base 1 to the rear of the processing base 1 through the fish and shrimp tweezers 25.

[0084] Specifically, multiple sets of synchronous pulleys 23 and synchronous belts 24 are provided and evenly assembled into each strip-shaped through hole 16 to drive and remove fish and shrimp. The synchronous belts 24 can also effectively block the strip-shaped through holes 16 to prevent fish and shrimp from falling into the processing chamber 12 along the strip-shaped through holes 16.

[0085] When the active roller 21 rotates, the combination of the synchronous belt 24 and the synchronous pulley 23 can drive the driven roller 22 to rotate synchronously, thereby ensuring that the synchronous belt 24 and the fish and shrimp shovels 25 fixed on it operate stably in each strip-shaped through hole 16, so as to push the fish and shrimp passing by to the back of the processing base 1, which can prevent the fish and shrimp from blocking the through holes 13, and can also effectively prevent the fish and shrimp from being damaged or dying, thus improving the ecological environment protection effect of the river during the dredging of river sediment.

[0086] When the drive shaft 433 is running, the combination of two sets of second drive sprockets 437 and matching second drive chains drives the active roller 21 to run effectively. Then, through the cooperation and installation of the active roller 21 and the driven roller 22, and the synchronous pulley 23 and synchronous belt 24 arranged on it, the fish and shrimp protection component can run effectively.

[0087] Support Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 In one embodiment of the river silt ecological dredging equipment, to facilitate the disassembly, assembly, and maintenance of the components assembled in the treatment base 1 and to facilitate the production and manufacturing of the treatment base 1, mounting covers 17 are fixedly mounted on both sides of the treatment base 1. The treatment chamber 12, water storage chamber 14, and transmission chamber 15 extend to the outside of the treatment base 1 on both sides and are sealed by the mounting covers 17. The two ends of the drive roller 21, driven roller 22, fourth mounting shaft 431, and transmission shaft 433 are rotatably mounted on the mounting covers 17. A protective cover 171 is also fixedly connected to the outside of the mounting covers 17. The first transmission sprocket 436, the second transmission sprocket 437, and the matching first and second transmission chains are all assembled into the corresponding protective covers 171, which can effectively protect them and ensure their stability during underwater operation.

[0088] In summary, the design of the shovel teeth 111 of this invention ensures that the shovel head 11 effectively shovels up the silt deposited in the river channel, ensuring subsequent silt treatment. The coordinated arrangement of the first guide slope, the second guide slope, and the arc-shaped transition surface ensures that the shoveled silt flows along the shovel head 11 and the front side of the treatment base 1. Then, under the negative pressure generated by the operation of the mud-water separation component, it is pumped into the treatment chamber 12 along with the river water for further processing. When the submersible pump 32 is running, it can pump the river water above the filter baffle 31 into the water storage chamber 14 below the treatment chamber 12. At the same time, the filter baffle 31 intercepts the silt above it. In this state, the negative pressure generated by the pumping of river water from the water storage chamber 14 causes the silt and river water mixture shoveled outside the treatment base 1 to be pumped into the treatment chamber 12 through the interception hole 13, continuously feeding the silt to be cleaned into the treatment chamber 12. Meanwhile, the interception hole 13 isolates passing fish and shrimp from the outside. The river water pumped into the water storage chamber 14 is ultimately output from the front of the shovel head 11. The output river water washes away the deposited silt, improving the shovel teeth 111's ability to lift the silt and ensuring efficient silt removal. The river water pumped by the submersible pump 32 can be discharged through the main drainage pipe 333 and branch drainage pipes 332, ensuring the water storage chamber 14 is under continuous negative pressure. The discharged river water is ultimately sprayed from the drainage nozzle 331 onto the front of the shovel head 11, washing away the deposited silt and making it easier for the shovel teeth 111 to reach the bottom of the silt and lift it, thus improving silt removal efficiency. At the same time, it ensures that the intercepted silt can effectively accumulate at the bottom of the treatment chamber 12 and be discharged externally using the sludge discharge assembly. Mounting base plate 411 can be assembled to the stern of the engineering vessel using bolts or snap-fit ​​connections to ensure effective connection between the sludge removal assembly and the engineering vessel. The engineering vessel then propels the sludge removal assembly and the treatment base 1 through the river channel. With the coordinated operation of the shovel head 11, fish and shrimp protection assembly, mud-water separation assembly, and sludge removal assembly, the deposited silt is cleared and transported ashore. The three-section design of the transverse transmission cylinder 412, longitudinal transmission cylinder 413, and transfer transmission cylinder 414, combined with hinges, improves overall flexibility, ensuring the engineering vessel can stably tow the treatment base 1, which has sunk to the riverbed. The transfer transmission cylinder is hinged to the treatment base 1, ensuring effective contact between the treatment base 1 and the riverbed, thus effectively shoveling up the silt deposited at the riverbed. The hydraulic telescopic cylinder 415 adjusts the angle between the transverse transmission cylinder 412 and the transfer transmission cylinder 414, thereby controlling the rising or falling posture of the treatment base 1. When the hydraulic telescopic cylinder 415 retracts, the angle between the transverse transmission cylinder 412 and the transfer transmission cylinder 414 decreases, and the processing base 1 sinks as a whole. When the hydraulic telescopic cylinder 415 extends, the angle between the transverse transmission cylinder 412 and the transfer transmission cylinder 414 increases and gradually approaches 180°, which can raise the processing base 1 above the river surface.The power output device is typically a gas turbine or drive motor mounted on an engineering vessel. Its output shaft is connected to the first mounting shaft 421 via a dedicated coupling. When the controller is running, due to the arrangement of the universal coupling 427, power can be stably transmitted along the first mounting shaft 421, the second mounting shaft 422, and the third mounting shaft 423, thereby driving the first spiral conveyor blade 424, the second spiral conveyor blade 425, and the third spiral conveyor blade 426 to operate effectively. The first spiral conveyor blade 424 is in close contact with the inner wall of the transverse transmission cylinder 412, the second spiral conveyor blade 425 is in close contact with the inner wall of the longitudinal transmission cylinder 413, and the third spiral conveyor blade 426 is in close contact with the inner wall of the transfer transmission cylinder 414. When each spiral conveyor blade is running, it can drive the sludge collected in the treatment chamber 12 to be transmitted along the longitudinal transmission cylinder 413, the transfer transmission cylinder 414, and the flexible corrugated pipe 417 to the transverse transmission cylinder 412, and then discharged from the sludge discharge port 416. When the second mounting shaft 422 drives the first bevel gear 434 to rotate, it can drive the second bevel gear 435 and the transmission shaft 433 fixed to the second bevel gear 435 to transmit power stably. Then, through the combination of the first transmission sprocket 436 and the matching first transmission chain, it drives the fourth mounting shaft 431 to rotate stably, thereby causing the two sets of fourth spiral conveying blades 432 mounted on the fourth mounting shaft 431 to rotate stably. The combination of the processing chamber 12 and the filter baffle 31 makes the bottom of the processing chamber 12 form an arc structure. The fourth mounting shaft 431 is arranged at the arc structure, and the fourth spiral conveying blades 432 are in close contact with the arc structure. When the two sets of fourth spiral conveying blades 432 rotate, they can drive the silt evenly distributed in the arc structure to move towards the longitudinal transmission cylinder 413 at the center, so that the longitudinal transmission cylinder 413 can effectively receive the silt and transfer it to both banks of the river through the guide mechanism and the transmission mechanism. The intercepting through-hole 13 of the present invention can prevent fish and shrimp from entering the processing chamber 12, while ensuring that the shoveled silt can enter normally. Under the drive of the sludge discharge component, the fish and shrimp protection component can drive away the passing fish and shrimp, thereby improving the ecological environment protection effect of the river during the dredging of river silt. While ensuring the traction of the processing base 1 and the components therein, the sludge discharge component can discharge the silt collected therein, and can also effectively transmit the power of the power output device installed on the engineering vessel to the processing base 1, thereby driving the fish and shrimp protection component to operate effectively. The coordinated operation of the processing base 1 and the mud-water separation component therein can quickly shovel and collect the silt at the bottom of the river, thereby effectively improving the efficiency of river dredging.

[0089] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
