Description

Technical Field

[0001] This invention relates to the field of dredging equipment technology, and in particular to a river dredging equipment for municipal construction projects. Background Technology

[0002] In municipal construction projects, river dredging is a crucial step in improving the aquatic environment and ensuring drainage capacity. However, existing dredging equipment commonly suffers from clogging of the sludge pumping device during actual operation, severely impacting construction efficiency and dredging effectiveness. When pumping high-concentration sludge or sludge containing debris (such as branches, stones, and plastic bags), traditional equipment often experiences frequent pipe blockages due to improper pipe diameter design or a lack of effective anti-clogging mechanisms. This not only increases downtime for cleaning but may also accelerate component wear due to repeated start-ups and shutdowns.

[0003] Therefore, the present invention provides a river dredging device for municipal construction projects, which avoids the need to stop the machine for cleaning after the dredging device is blocked, thereby reducing cleaning time and the number of times the equipment is started and stopped, and improving the dredging efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a river dredging equipment for municipal construction projects, which can dredge the dredging device, reduce downtime for cleaning and the number of times the equipment is started and stopped, so as to improve the efficiency of dredging.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A river dredging device for municipal construction projects includes:

[0007] The frame includes a support plate, the support plate having a supporting surface and a bottom surface, the supporting surface and the bottom surface being disposed opposite to each other;

[0008] A sludge-dredging device is installed on the support plate. The sludge-dredging device includes a base, a connecting rod, a suction head, and a sludge-dredging pipe. The base is installed on the support plate. One end of the connecting rod is connected to the base and extends sequentially away from the supporting surface and the bottom surface along the direction of gravity. The other end of the connecting rod is connected to the suction head. The suction head has a sludge-dredging port, a sludge-discharge port, and an air inlet. The sludge-dredging pipe has a sludge-inlet port and a sludge-discharge port. The sludge-dredging port, the sludge-discharge port, the sludge-inlet port, and the sludge-discharge port are sequentially connected to form a sludge-discharge channel for cleaning river silt.

[0009] A mud pump, which is connected to the mud pumping device and is used to provide mud pumping power to the mud pumping device;

[0010] An anti-clogging device includes a dredging pump and a dredging pipe. The dredging pump is installed on the support plate. The dredging pipe has an air inlet and an air outlet. The two ends of the dredging pipe are respectively connected to the dredging pump and the suction head. The air inlet, the air outlet, the air inlet, and the sludge suction port are sequentially connected to form a dredging air passage. The dredging air passage is used to clean the blocked suction head.

[0011] Furthermore, the sludge removal device also includes a first linear drive mechanism, which is mounted on the base and drivenly connected to the connecting rod. The first linear drive mechanism is used to drive the connecting rod to move the suction head closer to or away from the bottom surface. The unblocking pipe is a first telescopic pipe with a first telescopic segment. The first telescopic segment extends along the extension direction of the connecting rod so that the first telescopic pipe can follow the suction head closer to or away from the bottom surface.

[0012] Furthermore, the air outlet and the mud inlet are connected, and the mud suction pipe is a second telescopic pipe. The second telescopic pipe has a second telescopic segment, which extends along the extension direction of the connecting rod, so that the second telescopic pipe can follow the suction head to approach or move away from the bottom surface.

[0013] Furthermore, the sludge suction pipe is equipped with a valve, which is used to open or close the sludge discharge channel.

[0014] Furthermore, the river dredging equipment for municipal construction projects also includes a mud-turning machine and a baffle plate. The mud-turning machine includes a rotary drive mechanism and a mud-turning device. The rotary drive mechanism is installed on the support plate, and the mud-turning device is connected to the rotary drive mechanism in a transmission manner. The mud-turning device is located at the traveling end of the river dredging equipment for municipal construction projects and below the bottom surface. The baffle plate is installed on the support plate and extends along the extension direction of the connecting rod. The baffle plate, the mud-turning device, and the suction head are distributed sequentially in the horizontal direction. The baffle plate is used to block debris turned out by the mud-turning device. The baffle plate has multiple water passage holes, which penetrate both sides of the baffle plate along the wall thickness direction. The water passage holes are used to reduce the resistance when the dredging equipment is working and moving.

[0015] Furthermore, the aforementioned river dredging equipment for municipal construction projects also includes a sludge storage box and a drainage pipe. The sludge storage box is installed on the supporting surface and has a accommodating space and a pressure plate. The pressure plate is located within the accommodating space and divides the accommodating space into a sludge storage chamber and a drainage chamber. One end of the sludge suction pipe is connected to the sludge storage box, and the sludge discharge port is connected to the sludge storage chamber. The drainage pipe has an inlet and a outlet, and one end of the drainage pipe is connected to the sludge storage box. The drainage chamber, the inlet, and the outlet are sequentially connected.

[0016] Furthermore, the mud storage box is connected to a second linear drive mechanism, which is driven by the water pressure plate. The second linear drive mechanism is used to drive the water pressure plate to press out the water from the sludge.

[0017] Furthermore, the mud storage chamber has a first lateral opening and a second lateral opening. The first lateral opening is provided with an opening and closing door, which is used to open or close the first lateral opening. The mud storage box is also connected to a push plate and a push mechanism. The push plate covers the second lateral opening, and the push mechanism is drivenly connected to the push plate. The push mechanism is used to drive the push plate to move closer to or away from the first lateral opening so as to push the formed sludge out of the mud storage chamber.

[0018] Furthermore, the rotary drive mechanism includes a drive wheel, a motor, a driven wheel, and a transmission belt. The drive wheel is driven and connected to the motor, the driven wheel is driven and connected to the mud turner, and the transmission belt is wound around the drive wheel and the driven wheel so that the mud turner rotates in the direction of rotation of the transmission belt.

[0019] Furthermore, the rotary drive mechanism is disposed on the support surface, and the support plate has a through hole extending along the wall thickness direction, the through hole being used for the transmission belt.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The design of using a dredging pump with an anti-clogging device to unclog the suction head achieves rapid unblocking and reduces downtime. This device employs a dredging pump anti-clogging system that uses high-pressure airflow to quickly unclog the suction head. When the suction head becomes clogged due to viscous sludge or accumulated impurities, the dredging pump generates high-pressure airflow in a very short time, directly acting on the clogged area through a specially designed airflow channel. This pneumatic unblocking method has significant advantages over traditional manual or mechanical cleaning. It offers a faster response time and can complete the unblocking operation with no or only short-term downtime, ensuring the continuity of dredging work. The instantaneous impact force generated by the high-pressure airflow effectively decomposes and removes various blockages, including fibrous impurities and hardened sludge, and the entire process requires no disassembly of equipment parts. This design is particularly suitable for large-scale dredging scenarios requiring continuous operation, significantly improving overall work efficiency by reducing downtime maintenance. Simultaneously, operators can adjust the air pressure intensity according to the degree of blockage, ensuring unblocking effectiveness while avoiding energy waste, demonstrating excellent energy-saving characteristics.

[0022] 2. The non-contact airflow cleaning technology employed in this anti-clogging device effectively reduces mechanical wear during equipment operation. Traditional mechanical unblocking methods often require physical contact to remove blockages, inevitably causing frictional damage to the internal structure of the suction head. Long-term use will lead to premature failure of critical components. This solution, however, relies entirely on air pressure for unblocking, avoiding direct contact between mechanical parts and fundamentally solving the wear problem. This design not only extends the service life of core components such as the suction head and connecting rod but also reduces the frequency and cost of equipment maintenance. The advantages of non-contact unblocking are particularly evident when handling sludge containing hard impurities such as sand and gravel, effectively removing blockages without damaging the internal walls of the equipment due to friction from hard objects. Furthermore, this technology reduces the number of times the equipment is disassembled, lowering the risk of seal aging caused by frequent disassembly, further improving the reliability of the entire system and ensuring long-term stable operation.

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. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See Figures 1-5A preferred embodiment of the present invention provides a river dredging device for municipal construction projects, comprising a frame 1, a dredging device 2, a dredging pump, and an anti-clogging device 3. The frame 1 includes a support plate 101, which has a supporting surface 111 and a bottom surface 122, which are arranged opposite to each other. The dredging device 2 is installed on the support plate 101 and includes a base 201, a connecting rod 202, a suction head 203, and a dredging pipe 204. The base 201 is installed on the support plate 101. One end of the connecting rod 202 is connected to the base 201 and extends sequentially away from the supporting surface 111 and the bottom surface 122 along the direction of gravity. The other end of the connecting rod 202 is connected to the suction head 203. The suction head 203 has a dredging port 211, a dredging outlet 212, and a dredging pipe 204. The air inlet 213 and the sludge suction pipe 204 have a sludge inlet 215 and a sludge outlet 216. The sludge suction outlet 211, the sludge outlet 212, the sludge inlet 215 and the sludge outlet 216 are connected in sequence to form a sludge discharge channel, which is used to clean the river silt. The sludge pump is connected to the sludge pump and is used to provide sludge pumping power to the sludge pumping device 2. The anti-clogging device 3 includes a dredging pump 301 and a dredging pipe 302. The dredging pump 301 is installed on the support plate 101. The dredging pipe 302 has an air inlet 311 and an air outlet 312. The two ends of the dredging pipe 302 are connected to the dredging pump 301 and the suction head 203, respectively. The air inlet 311, the air outlet 312, the air inlet 213 and the sludge suction outlet 211 are connected in sequence to form a dredging air passage, which is used to clean the blocked suction head 203.

[0033] The working principle of this invention is as follows: The support plate 101 serves as the bearing foundation of the overall structure, with its supporting surface 111 used to install the sludge pumping device 2 and the anti-clogging device 3, and its bottom surface 122 connected to the external support structure. The sludge pumping device 2 is fixed to the support plate 101 via the base 201, and the connecting rod 202 extends along the direction of gravity, allowing the suction head 203 to penetrate deep into the silt area of ​​the river channel. When the device is working, the sludge pump starts, causing the sludge to be sucked into the sludge inlet 211 of the suction head 203, enters the sludge inlet 215 of the sludge pumping pipe 204 through the sludge outlet 212, and is finally discharged from the sludge outlet 216, forming a continuous sludge discharge channel and achieving efficient cleaning of river silt. During dredging, if the sludge is viscous or contains impurities, causing blockage of the suction head 203, the anti-blocking device 3 is activated: the dredging pump 301 delivers high-pressure gas from the vent 311 to the outlet 312 through the dredging pipe 302, and then injects it into the dredging port 211 through the air inlet 213 of the suction head 203, causing the gas to be ejected from the dredging port 211. The high-pressure gas creates a violent disturbance at the dredging port 211, dispersing or expelling the blockage, thereby clearing the pipe 302. The coordinated design of the dredging airway and the sludge discharge channel ensures the continuity of sludge removal and improves the reliability of the system through the air pressure anti-blocking mechanism, making it suitable for river dredging operations under complex conditions.

[0034] Clearly, the design of using the unblocking pump 301 to unclog the suction head 203 based on the anti-clogging device 3 achieves rapid unblocking and reduces downtime. The unblocking pump 301 anti-clogging system in this device achieves rapid unblocking of the suction head 203 through high-pressure airflow impact. When the suction head 203 becomes clogged due to viscous sludge or accumulated impurities, the unblocking pump 301 can generate high-pressure airflow in a very short time, directly acting on the clogged area through a specially designed unblocking air passage. This pneumatic unblocking method has significant advantages over traditional manual or mechanical cleaning. It has a faster response speed and can complete the unblocking operation without stopping or with short-term downtime, ensuring the continuity of dredging work. The instantaneous impact force generated by the high-pressure airflow can effectively decompose and remove various blockages, including fibrous impurities and hardened sludge, and the entire process does not require disassembly of equipment parts. This design is particularly suitable for large-scale dredging scenarios that require continuous operation, significantly improving overall work efficiency by reducing downtime maintenance time. At the same time, the operator can adjust the air pressure intensity according to the degree of blockage, ensuring unblocking effect while avoiding energy waste, demonstrating good energy-saving characteristics.

[0035] In this embodiment, the non-contact airflow cleaning technology employed by the anti-clogging device 3 effectively reduces mechanical wear during equipment operation. Traditional mechanical unblocking methods often require physical contact to remove blockages, which inevitably causes frictional damage to the internal structure of the suction head 203, leading to premature failure of critical components with prolonged use. In contrast, this airflow unblocking solution relies entirely on air pressure, avoiding direct contact between mechanical parts and fundamentally solving the wear problem. This design not only extends the service life of core components such as the suction head 203 and connecting rod 202 but also reduces the frequency and cost of equipment maintenance. The advantages of non-contact unblocking are particularly evident when handling sludge containing hard impurities such as sand and gravel, effectively removing blockages without damaging the inner wall of the equipment due to friction from hard objects. Furthermore, this technology reduces the number of times the equipment is disassembled, lowering the risk of seal aging caused by frequent disassembly, further improving the reliability of the entire system and ensuring long-term stable operation.

[0036] In this embodiment, the unblocking pump 301 and unblocking pipe 302 can be an air pump and air pipe, or a water pump and water pipe. The air pump unblocking system is suitable for conventional dredging scenarios, quickly clearing blockages with high-pressure airflow, offering advantages such as fast response and low energy consumption. The water pump unblocking system is more suitable for handling highly viscous sludge or conditions containing a large amount of solid impurities, using water flow to more thoroughly unclog pipe 302. Both solutions achieve non-contact unblocking, effectively reducing equipment wear, and can be flexibly selected or combined according to actual working conditions, significantly improving equipment adaptability and operational efficiency.

[0037] It is worth noting that in this embodiment, the anti-blocking device 3 can be controlled manually or automatically by integrating control equipment. Specifically, pressure sensors are installed at key locations in the 204 sludge suction pipes to monitor internal pressure changes in real time. When an abnormal pressure increase is detected, the system automatically determines that a blockage has occurred. The control unit immediately initiates a preset program, first briefly stopping the sludge suction pump, and then activating the high-pressure unblocking pump 301, which delivers compressed air to the blocked area according to a set pressure curve. During the unblocking process, the system continuously monitors pressure feedback and dynamically adjusts the airflow intensity and duration until the pressure returns to normal. The entire process is fully automated. To ensure operational safety, the system is equipped with multiple protection mechanisms, including air pressure upper limit protection, abnormal status alarm, and manual emergency stop function. Operators can view the unblocking status in real time through the touch screen interface and manually adjust parameters when necessary, so that operators of different experience levels can safely and efficiently complete complex dredging tasks, while extending the service life of the equipment.

[0038] More preferably, the sludge pumping device 2 further includes a first linear drive mechanism 4, which is mounted on the base 201 and drivenly connected to the connecting rod 202. The first linear drive mechanism 4 drives the connecting rod 202 to move the suction head 203 closer to or away from the bottom surface 122. The unblocking pipe 302 is a first telescopic pipe with a first telescopic segment 313 extending along the extension direction of the connecting rod 202, allowing the first telescopic pipe to follow the suction head 203 closer to or away from the bottom surface 122. This sludge pumping device 2, through the integration of the first linear drive mechanism 4 and the first telescopic pipe, improves the operational flexibility and reliability of the equipment. The first linear drive mechanism 4 can precisely control the telescopic movement of the connecting rod 202, allowing the suction head 203 to flexibly adjust its working depth according to actual working conditions. It can fully penetrate the sludge layer for efficient suction and quickly retract when encountering obstacles or completing the operation, greatly enhancing the equipment's adaptability to different water depths and sludge thicknesses. The specially designed first telescopic pipe with a first telescopic segment 313 can extend and retract synchronously with the connecting rod 202, ensuring that the unblocking pipe 302 maintains good ventilation performance whenever the suction head 203 changes position. This avoids the problems of entanglement, stretching, or detachment that may occur with traditional fixed-length unblocking pipes 302 when the equipment moves. This synchronous telescopic design not only ensures that the anti-clogging system can work normally at any working depth, but also reduces the risk of pipe wear and extends the service life of the equipment. At the same time, the integrated drive system makes the equipment easier to operate. Operators can complete depth adjustment and suction operations simply through the control panel, thereby improving work efficiency and reducing operational difficulty. It is particularly suitable for complex dredging scenarios that require frequent adjustments to the working depth. It is worth noting that the first telescopic pipe should be made of a material with high pressure resistance to adapt to the pressure of different water depths and the gas pressure required for ventilation.

[0039] More preferably, the air outlet 312 and the mud inlet 215 are connected, and the mud suction pipe 204 is a second telescopic pipe with a second telescopic segment 214. The second telescopic segment 214 extends along the extension direction of the connecting rod 202, so that the second telescopic pipe can follow the suction head 203 to approach or move away from the bottom surface 122. This design, by directly connecting the air outlet 312 and the mud inlet 215, expands the functional coverage of the anti-clogging device 3, enabling it to not only unclog the suction head 203 but also prevent clogging of the mud suction pipe 204. This integrated design allows high-pressure airflow to act on both the suction head 203 and the mud suction pipe 204 simultaneously. When the mud suction pipe 204 is blocked, the compressed air generated by the anti-clogging device 3 can enter the mud suction pipe 204 through the suction head 203, forming a strong airflow impact that effectively decomposes and removes stubborn sludge or impurities accumulated in the pipe. The structural design of the second telescopic pipe ensures that the pipeline remains airtight during its expansion and contraction, allowing the anti-clogging airflow to be delivered to the blocked area without damage. In this embodiment, the two most prone to clogging in traditional equipment are incorporated into a unified protection system. This design avoids the complexity of adding additional anti-clogging pipelines and simplifies the system structure by optimizing the airflow path, reducing manufacturing costs and improving maintenance convenience. In actual operation, this integrated anti-clogging system can handle various complex working conditions, especially for treating sludge containing fibrous impurities or with high viscosity, ensuring continuous and stable dredging operations. It is worth noting that when the anti-clogging device 3 clears the sludge suction pipe 204, to prevent air leakage from the suction port 211, the suction head 203 can be inserted into the sludge first, or a sealing switch can be added.

[0040] More preferably, the sludge suction pipe 204 is equipped with a valve 5, which is used to open or close the sludge discharge channel. The valve 5 is made of wear-resistant alloy material. During regular sludge suction operations, the valve 5 remains fully open to ensure unobstructed sludge discharge. When the equipment is blocked in anti-blockage mode, the valve 5 can work in conjunction with the unblocking pump 301 to implement various control strategies: for example, completely closing to form a sealed chamber, allowing high-pressure airflow to concentrate on the blocked area, or adjusting the opening to control the sludge discharge speed and prevent secondary blockage. This coordinated work of the controllable valve 5 and the telescopic pipe structure ensures both the sealing performance during pipe expansion and contraction and seamless switching between operating modes. Its advantages lie in improving anti-blockage efficiency, reducing airflow loss, preventing sludge backflow, and extending the service life of the pipe. Especially when handling high-concentration sludge containing solid impurities, the precise control of the valve 5 can effectively prevent pipe blockage and ensure the stability of continuous operation.

[0041] More preferably, the river dredging equipment for municipal construction projects further includes a mud-turning machine 6 and a baffle plate 7. The mud-turning machine 6 includes a rotary drive mechanism 601 and a mud-turning device 602. The rotary drive mechanism 601 is installed on the support plate 101, and the mud-turning device 602 is connected to the rotary drive mechanism 601. The mud-turning device 602 is located at the traveling end of the river dredging equipment for municipal construction projects and below the bottom surface 122. The baffle plate 7 is installed on the support plate 101 and extends along the extension direction of the connecting rod 202. The baffle plate 7, the mud-turning device 602, and the suction head 203 are distributed sequentially in the horizontal direction. The baffle plate 7 is used to block debris turned out by the mud-turning device 602. The baffle plate 7 has multiple water passage holes 701. The water passage holes 701 penetrate both sides of the baffle plate 7 along the wall thickness direction. The water passage holes 701 are used to reduce the resistance when the dredging equipment is working. In one embodiment, the river dredging equipment incorporates a sludge turner 6 and a baffle plate 7, thereby improving dredging efficiency and work quality. The sludge turner 6, through a rotary drive mechanism 601, drives the sludge turner 602 to mechanically agitate the deposited sludge, breaking up and turning over the hardened bottom sludge, thus resuspending the stubborn sludge that has been deposited for a long time in the water, creating favorable conditions for subsequent suction operations. The specially designed baffle plate 7 is located between the sludge turner 602 and the suction head 203 or at the front end of the sludge turner 602. Its unique structure effectively intercepts large debris such as stones and branches brought up during the sludge turning process, preventing these debris from entering the suction system and causing blockages or damage. Furthermore, the rationally arranged water passage holes 701 ensure smooth water flow, reducing the equipment's resistance to movement. This three-stage operation mode (mud turning-blocking-suction) forms a complete dredging production line. The mud turning device 602 ensures that the silt is fully loosened, the blocking plate 7 screens out debris, and the suction head 203 completes efficient extraction. The synergy of these three components significantly improves dredging efficiency. The design of the water passage 701 adopts a fluid dynamics optimized arrangement, minimizing water flow resistance while ensuring blocking effect, allowing the equipment to maintain a stable travel speed even when operating in deep water. This design is particularly suitable for handling years of accumulated silt, effectively solving the problem of low suction efficiency of traditional dredging equipment for compacted silt, while significantly reducing the equipment failure rate caused by debris and extending the service life of key components.

[0042] More preferably, the river dredging equipment for municipal construction projects further includes a sludge storage box 8 and a drainage pipe 17. The sludge storage box 8 is installed on the support surface 111. The sludge storage box 8 has a accommodating space 801 and a water pressure plate 9. The water pressure plate 9 is disposed in the accommodating space 801 and divides the accommodating space 801 into a sludge storage chamber 811 and a drainage chamber 812. One end of the sludge suction pipe 204 is connected to the sludge storage box 8. The sludge discharge port 216 is connected to the sludge storage chamber 811. The drainage pipe 17 has an inlet 171 and a outlet 172. One end of the drainage pipe 17 is connected to the sludge storage box 8. The drainage chamber 812, the inlet 171, and the outlet 172 are connected in sequence. The sludge storage tank 8 employs a pressure plate 9 design, scientifically dividing its internal space into a sludge storage chamber 811 and a drainage chamber 812, forming an efficient sludge treatment process: After the water-containing sludge enters the sludge storage chamber 811 through the sludge suction pipe 204, when the sludge volume reaches the height of the pressure plate 9, the pressure plate 9 applies uniform pressure to the sludge, causing water to seep through the filter layer of the pressure plate 9 into the drainage chamber 812, simultaneously compressing and storing the sludge. The drainage system, through an optimized pipe design, orderly discharges the separated water, achieving on-site immediate dewatering and eliminating the secondary transfer step in traditional processes. The pressure plate 9 can adjust pressure parameters according to the sludge characteristics to ensure optimal dewatering effect and significantly reduce the sludge moisture content. The separated water, after natural sedimentation, flows back into the river through the drainage pipe 17, saving water resources and avoiding secondary pollution, making it particularly suitable for treating sludge with high moisture content. The entire system reduces sludge transportation volume and subsequent treatment costs, realizing a complete operation process from sludge removal to dewatering.

[0043] More preferably, the sludge storage tank 8 is connected to a second linear drive mechanism 10, which is driven by the pressure plate 9. The second linear drive mechanism 10 is used to drive the pressure plate 9 to press out the water from the sludge. The second linear drive mechanism 10 adopts a hydraulic or electric push rod design and is directly connected to the pressure plate 9 of the sludge storage tank 8. It can intelligently adjust the applied pressure and speed according to the characteristics of the sludge. When the water-containing sludge enters the sludge storage chamber 811, the drive mechanism drives the pressure plate 9 to perform multi-stage compression: first, the sludge initially settles under lower pressure, then the pressure is gradually increased to fully squeeze out the water, and finally, constant pressure is maintained to ensure the dewatering effect. This controllable pressurization method is more efficient than traditional gravity dewatering and can adapt to the sludge treatment needs of different moisture contents. The cooperation between the pressure plate 9 and the sludge storage chamber 811 ensures uniform pressure distribution, which not only improves the dewatering efficiency but also avoids equipment damage caused by excessive local pressure. This design not only significantly improves sludge treatment efficiency but also greatly reduces subsequent transportation and treatment costs, while ensuring the stability and reliability of the operation process.

[0044] More preferably, the sludge storage chamber 811 has a first lateral opening 11 and a second lateral opening 12. The first lateral opening 11 is equipped with an opening and closing door 13, which is used to open or close the first lateral opening 11. The sludge storage box 8 is also connected to a push plate 15 and a push mechanism 14. The push plate 15 covers the second lateral opening 12, and the push mechanism 14 is drivenly connected to the push plate 15. The push mechanism 14 is used to drive the push plate 15 closer to or further away from the first lateral opening 11 to push the formed sludge out of the sludge storage chamber 811. The sludge storage chamber 811 adopts a bidirectional opening design. The first lateral opening 11 is equipped with an opening and closing door 13, which is precisely controlled by electric or hydraulic drive. It maintains a sealed state during the sludge dewatering stage to ensure pressure effect and opens smoothly during the sludge discharge stage. The second lateral opening 12 is equipped with a push mechanism 14, which uses a high-strength push plate 15 combined with a linear drive device to generate a stable pushing force. After the sludge has been dewatered, the control system first opens the opening / closing door 13 of the first lateral opening 11. Then, the jacking mechanism 14 drives the jacking plate 15 to move horizontally, pushing the formed sludge block out of the sludge storage chamber 811 as a whole. The jacking process is smooth and uniform, ensuring that the formed sludge maintains its intact structure for easy transportation; the fully automated operation reduces manual intervention and improves operational safety; the pusher-plate sludge discharge design solves the problem of residue in traditional sludge discharge methods. It is particularly suitable for large-scale continuous dredging operations, providing an efficient and reliable sludge treatment solution for municipal engineering projects.

[0045] More preferably, the rotary drive mechanism 601 includes a drive wheel 611, a motor 612, a driven wheel 613, and a transmission belt 614. The drive wheel 611 is driven by the motor 612, and the driven wheel 613 is driven by the silt turner 602. The transmission belt 614 is wound around the drive wheel 611 and the driven wheel 613, so that the silt turner 602 rotates in the same direction as the transmission belt 614. The motor 612, as a power source, is directly connected to the drive wheel 611 via a coupling to ensure high efficiency of power output. The driven wheel 613 is fixedly connected to the shaft of the silt turner 602 using a keyway to ensure reliable torque transmission. The high-strength transmission belt 614 adopts a toothed belt or chain design, which has excellent tensile strength and wear resistance, and can adapt to the harsh environment of underwater operation. This transmission arrangement is characterized by compact structure and high transmission efficiency, enabling the silt turner 602 to obtain stable rotational power and ensuring continuous and effective turning of riverbed silt. The system also features a tension adjustment device, allowing for real-time adjustment of the tension of the drive belt 614 to maintain optimal transmission performance. This structure minimizes energy consumption while ensuring sufficient torque output, making mud-turning operations both efficient and economical, and creating favorable conditions for subsequent mud-pumping processes.

[0046] More preferably, the rotary drive mechanism 601 is located on the support surface 111, and the support plate 101 has a through hole 16 extending along its wall thickness. The through hole 16 is used for the transmission belt 614. This dredging equipment adopts a vertically partitioned transmission design. The rotary drive mechanism 601 is located above the support plate 101 and transmits power to the sludge turner 602 below through the through hole 16. This layout keeps precision components such as the motor 612 away from the water body, improving equipment reliability and facilitating maintenance. The transmission system has a compact structure, efficient power transmission, and meets the waterproof and corrosion-resistant requirements of dredging operations.
