Description

Technical Field

[0001] This invention relates to a dredging device and a dredging method thereof, and particularly to a shore-based traction-type water conservancy dredging device and a dredging method thereof, belonging to the field of water conservancy engineering technology. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an essential and precious resource for human production and life. When rainwater washes away a large amount of mud, animal and plant carcasses and other debris, it flows into the riverbed, causing the river to become shallower and a lot of silt to accumulate at the bottom of the riverbed. If it is not cleaned in time, it will lead to a reduction in water storage. Too much silt will affect the ecological balance and threaten the survival of aquatic life.

[0003] However, existing high-pressure vacuum mud-grinding machines cannot effectively intercept large particles of impurities in the silt when dredging canals. This results in a large amount of impurities entering the inside of the mud-grinding machine, with large chunks of silt adhering to the pipes, causing blockages, damaging the mud pump, and reducing dredging efficiency.

[0004] Therefore, it is urgent to improve the dredging equipment to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an onshore towing-type water conservancy dredging device and its dredging method. This invention can stir solid silt into a turbid liquid with a relatively high density, intercept large particles, and then pump it into the interior of the mud-water separation tank through a mud pump to separate the mud and water again, thus completing the dredging process without causing pipe blockage and greatly improving the efficiency of dredging.

[0006] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0007] A shore-based towing-type dredging device includes:

[0008] The system includes a dredging bucket and a robotic arm supporting it. A tractor unit is fixedly connected to the bottom of the robotic arm, and the dredging bucket is secured to the tractor unit via the robotic arm. Therefore, the river channel can be cleaned by moving the tractor unit. The dredging bucket is fixed to the bottom of the robotic arm, resulting in a high-strength and stable structure. A sludge pump is connected to the dredging bucket via a sludge suction hose. When the dredging bucket cleans the silt, the mud-water mixture enters the dredging bucket and is then extracted by the sludge pump. A mud-water separation tank is also included, connected to the sludge pump. The input end of the sludge pump is connected to the dredging bucket via a sludge suction hose, and the output end of the sludge pump is connected to the inside of the mud-water separation tank via a sludge delivery pipe. This connection allows the mud-water mixture in the dredging bucket to be pumped into the mud-water separation tank. The system has a simple structure, and after mud-water separation in the mud-water separation tank, the dredging of the river channel silt is completed.

[0009] A cylindrical mixing motor is fixedly installed at the front end of the dredging bucket. This motor has several evenly distributed silt-crushing teeth for mixing the silt on the riverbed. On one side of the mixing motor, between it and the dredging bucket, several evenly distributed arc-shaped grids are fixedly installed. After the dredging bucket is placed on the riverbed, the mixing motor starts to pre-mix and excavate the silt. During this excavation, large particles such as tree branches are encountered. The silt-crushing teeth on the mixing motor break off these particles and allow them to enter the dredging bucket. Harder impurities are prevented from entering the dredging bucket by the arc-shaped grids, thus avoiding interference with subsequent dredging. To mitigate certain impacts and extend the service life of the device, the sludge bucket is equipped with a rotating spiral conveying mechanism. This mechanism includes a first spiral roller and a second spiral roller. One end of the first spiral roller is connected to a first motor, and one end of the second spiral roller is connected to a second motor. The first and second motors rotate in opposite directions. After the lumpy sludge enters the sludge bucket, it is stirred by the spiral conveying mechanism. The first and second motors on the spiral conveying mechanism move in opposite directions, which in turn drives the first and second spiral rollers to move in opposite directions. This allows for a further stirring of the sludge inside the sludge bucket, forming an emulsion that facilitates the sludge extraction by the sludge pump.

[0010] Inside the dredging bucket, below the screw conveyor mechanism, there is a mud-water chamber. The dredging hose extends into the mud-water chamber, and the silt that forms an emulsion is drawn into the mud-water chamber by the screw conveyor mechanism. The dredging pump is used to extract the silt from the mud-water chamber. The dredging pump connected to the dredging bucket pumps the silt from the mud-water chamber into the mud-water separation box. The mud-water separation box has a separation chamber. The upper part of the inner side of the separation chamber is connected to a drain pipe. Due to the greater weight of the mud in the mud-water, the water is concentrated in the upper part of the mud-water separation box and is discharged back into the river channel through the drain pipe. A sludge discharge port is opened on one side of the bottom side of the separation chamber. The bottom of the sludge discharge port is connected to a sludge discharge bucket. The accumulated silt will be discharged from the sludge discharge bucket to the riverbank.

[0011] Therefore, this invention can stir solid sludge into a turbid liquid with a relatively high density. After being pumped into the sludge-water separation tank by a sludge pump, the sludge and water are separated again to complete the sludge removal process without causing pipe blockage, thus greatly improving the efficiency of sludge removal.

[0012] Preferably, a motor support plate and a grid support plate are fixedly installed at the front end of the sludge hopper. The cylindrical mixing motor is fixedly installed on the motor support plate by a cylindrical motor fixing ring. An upper grid rod is fixedly installed on the grid support plate. A lower grid rod is fixedly installed between the motor support plates directly below the cylindrical mixing motor. Both the upper and lower grid rods are fixed on the sludge hopper, which improves the overall structural strength. Since the sludge crushing teeth on the cylindrical mixing motor are arc-shaped, multiple arc-shaped grids are fixedly installed between the cylindrical mixing motor and the screw conveyor mechanism. Several arc-shaped grids are evenly distributed on the upper or lower grid rods, and each sludge crushing tooth is located between every two arc-shaped grids. This does not affect the normal rotation of the cylindrical mixing motor, but can also turn and mix the sludge, and at the same time, can dig the sludge into the interior of the sludge hopper. The structure is simple and improves the efficiency of sludge removal.

[0013] Meanwhile, harder impurities can slide off the arc-shaped grid under the action of the sludge crushing teeth, meaning that hard objects cannot enter the sludge dredging bucket, thus preventing damage to the sludge pump and extending the service life of the device.

[0014] In addition, a drive shaft is fixedly connected to both the first and second spiral rollers. The drive shaft is connected to the output end of the first or second motor. The output ends of the first and second motors are both fixedly equipped with drive shafts. The first and second spiral rollers are fixed on the drive shafts. The first and second spiral rollers rotate in opposite directions. On the one hand, the sludge can be rolled into the interior of the mud and water chamber. On the other hand, large particles in the sludge can be crushed to improve the extraction efficiency and extend the service life of the device.

[0015] A motor housing is fixedly installed at the end of the sludge hopper away from the straight-tube mixing motor. The first motor or the second motor is fixedly installed inside the motor housing by a motor fixing plate. The first motor and the second motor are fixed inside the motor housing to prevent water from entering the first motor or the second motor and to extend their service life.

[0016] Preferably, a filter screen slot is provided on one side of the mud-water separation box, and a permeable hole connected to the drain pipe is provided on the filter screen slot. Since a certain pressure is required when the mud pump draws out the mud and water from the mud-water chamber, after the water is drawn into the separation chamber, it will enter the drain pipe through the permeable hole and then be discharged into the river again, reducing the waste of water resources. A filter screen is slidably installed inside the filter screen slot, and a separation box sealing cover is fixedly installed at the port of the mud-water separation box. Filter screen slide bars are fixedly installed on both sides of the filter screen and are slidably installed inside the filter screen slot. The filter screen can effectively filter other impurities, prevent the drain pipe from being blocked, and effectively intercept mud, improving the dredging effect. The filter screen slide bars on the filter screen can slide directly inside the filter screen slot, so the filter screen can be replaced.

[0017] The sediment accumulates inside the separation chamber. A straight-cylinder sludge discharge motor is rotatably installed at the connection between the sludge discharge port and the sludge discharge hopper. Several evenly distributed scraper blades are installed on the outer side of the straight-cylinder sludge discharge motor. After the straight-cylinder sludge discharge motor is started, the scraper blades on the straight-cylinder sludge discharge motor scrape the direction of the sludge discharge port, thereby discharging the sludge through the sludge discharge hopper onto the riverbank.

[0018] Preferably, the robotic arm includes a vertical support arm and a horizontal support arm. The horizontal support arm includes a right-angle connecting arm and a third hydraulic pump. The bottom of the third hydraulic pump is fixedly connected to the tractor. The horizontal support arm is directly fixed to the tractor via the third hydraulic pump, which enables the robotic arm to move. The output end of the third hydraulic pump is fixedly connected to one end of the right-angle connecting arm, allowing the height of the right-angle connecting arm to be adjusted, thereby adjusting the overall height of the robotic arm. The other end of the right-angle connecting arm is connected to a second hydraulic pump, which is fixedly connected to the output end of the second hydraulic pump. The other end of the second hydraulic pump is fixedly connected to a horizontal connecting rod. In addition, the second hydraulic pump can extend the overall length of the robotic arm, which can expand the dredging range and retract the entire robotic arm onto the tractor for easy transportation.

[0019] The vertical support arm includes a sludge bucket fixing block and a connecting block. The bottom of the sludge bucket fixing block is fixedly mounted on the upper side of the sludge bucket. The sludge bucket is fixed to the robotic arm via the sludge bucket fixing block, improving the stability of the robotic arm. A vertical connecting rod is connected to the top of the first hydraulic pump. The upper end of the vertical connecting rod is fixedly connected to the connecting block. The sludge bucket fixing block is fixedly connected to the output end of the first hydraulic pump. The first hydraulic pump can lower the height of the sludge bucket and increase the sludge removal range. The horizontal connecting rod is fixedly connected to one side of the connecting block, improving the overall stability of the robotic arm. Specifically, during transportation:

[0020] The first hydraulic pump lifts the sludge bucket, the third hydraulic pump lifts the robotic arm, and the second hydraulic pump retracts the sludge bucket onto the tractor.

[0021] Preferably, a hose support rod is fixedly connected to the second hydraulic pump by a support rod screw. A hose fixing ring is fixedly installed at one end of the hose support rod. The sludge suction hose is installed inside the hose fixing ring. When the sludge suction pump draws mud and water from the sludge bucket through the sludge suction hose, the sludge suction hose will be subjected to a certain tension. Therefore, fixing the sludge suction hose to the robotic arm by the hose support rod can improve the stability of the sludge suction hose.

[0022] Similarly, the bottom of the sludge pump, sludge-water separation tank, and robotic arm are all fixedly connected to an assembly plate. The assembly plate has several evenly distributed assembly holes. The assembly plate is fixed to the tractor by bolts passing through the assembly holes. The sludge pump, sludge-water separation tank, and robotic arm are fixed to the tractor by bolts passing through the assembly holes on the assembly plate, thereby improving the overall stability.

[0023] A dredging method for a shore-based towing-type hydraulic dredging device includes the following steps:

[0024] Step 1: Secure the robotic arm. Secure the robotic arm, mud pump, and mud-water separation box to the tractor using the assembly plate. Use the tractor to tow the device to the appropriate location on the riverbank.

[0025] Step 2: Adjusting the sludge bucket. The horizontal and vertical positions of the sludge bucket are adjusted using the first, second, and third hydraulic pumps on the robotic arm, and the sludge bucket is then inserted deep into the sludge.

[0026] Step 3: The dredging bucket is braked. The straight-tube stirring motor drives the silt crushing teeth to break up the silt in the riverbed, and then the silt enters the dredging bucket. Under the action of the screw conveyor mechanism, the silt is further stirred.

[0027] Step 4: Sludge extraction. Start the sludge pump and extract the sludge from inside the sludge-water chamber through the sludge extraction hose, and send it into the sludge-water separation tank.

[0028] Step 5: Mud-water separation. Under the action of the mud-water separation box, mud and water are separated. After the water is separated from the mud-water separation box, it is discharged into the river through the drain pipe, and the silt is discharged to the shore through the sludge discharge bucket.

[0029] This invention has at least the following beneficial effects:

[0030] 1. This invention can stir solid sludge into a turbid liquid with a relatively high density. After intercepting large particles, the sludge and water are separated again after being pumped into the sludge-water separation tank by a sludge pump, thus completing the sludge removal process without causing pipe blockage and greatly improving the efficiency of sludge removal.

[0031] 2. After placing the dredging bucket on the riverbed, the straight-tube mixing motor on the dredging bucket is started to stir and excavate the silt on the riverbed. During the excavation process, large particles such as tree branches will be encountered. The silt crushing teeth on the straight-tube mixing motor will break off the tree branches and other debris and let them enter the dredging bucket. For impurities that are harder in material, they cannot enter the dredging bucket due to the obstruction of the arc-shaped grid, thus avoiding any impact on the subsequent extraction and extending the service life of the device.

[0032] 3. After the lumpy sludge enters the sludge hopper, it is stirred by the screw conveyor mechanism. The first and second motors on the screw conveyor mechanism move in opposite directions, which in turn drives the first and second screw rollers to move in opposite directions. This stirs the sludge that has entered the sludge hopper again, forming an emulsion that is easy for the sludge pump to extract.

[0033] 4. The height of the sludge bucket can be lowered by the first hydraulic pump, thereby increasing the sludge removal range. The horizontal connecting rod is fixedly connected to one side of the connecting block, which improves the overall stability of the robotic arm. During transportation, the sludge bucket is lifted by the first hydraulic pump, the robotic arm is lifted by the third hydraulic pump, and the sludge bucket is retracted onto the tractor by the second hydraulic pump.

Detailed Implementation

[0046] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0047] like Figures 1-10 As shown, the shore-based towing dredging device provided in this embodiment includes: a dredging bucket 1 and a mechanical arm 4 for supporting the dredging bucket 1. A tractor is fixedly connected to the bottom of the mechanical arm 4, and the dredging bucket 1 is fixed to the tractor via the mechanical arm 4. Therefore, the river channel can be cleaned by moving the tractor. The dredging bucket 1 is fixed to the bottom of the mechanical arm 4, resulting in high structural strength and stability. A sludge pump 2 is connected to the dredging bucket 1 via a sludge suction hose 201. When the dredging bucket 1 cleans the silt, the mud-water mixture then enters the dredging bucket 1. After entering the dredging bucket 1, the mud and water mixture is extracted by the mud pump 2 and then by the mud-water separation box 3. The mud-water separation box 3 is connected to the mud pump 2. The input end of the mud pump 2 is connected to the dredging bucket 1 through the mud pumping hose 201, and the output end of the mud pump 2 is connected to the inside of the mud-water separation box 3 through the mud delivery pipe 202. The mud pump 2 is connected to the inside of the mud-water separation box 3, so the mud and water mixture in the dredging bucket 1 can be pumped into the inside of the mud-water separation box 3. The structure is simple. After the mud and water are separated in the mud-water separation box 3, the cleaning of the river silt is completed.

[0048] A cylindrical stirring motor 5 is fixedly installed at the front end of the dredging bucket 1. The cylindrical stirring motor 5 has several evenly distributed silt-crushing teeth 502, which are used to stir the silt on the riverbed. Several evenly distributed arc-shaped grids 105 are fixedly installed on one side of the cylindrical stirring motor 5 between it and the dredging bucket 1. After the dredging bucket 1 is placed on the riverbed, the cylindrical stirring motor 5 on the dredging bucket 1 starts to pre-stir and excavate the silt on the riverbed. During the excavation process, large particles such as tree branches will be encountered. The silt-crushing teeth 502 on the cylindrical stirring motor 5 will break off the tree branches and other debris, allowing them to enter the interior of the dredging bucket 1. For harder impurities, the arc-shaped grids 105 prevent them from entering the interior of the dredging bucket 1, thus avoiding any impact on subsequent extraction. (The lifting device...) The sludge hopper 1 is equipped with a rotating spiral conveying mechanism 6, which includes a first spiral roller 601 and a second spiral roller 602. One end of the first spiral roller 601 is connected to a first motor 604, and one end of the second spiral roller 602 is connected to a second motor 605. The first motor 604 and the second motor 605 rotate in opposite directions. After the lumpy sludge enters the sludge hopper 1, it is stirred by the spiral conveying mechanism 6. The first motor 604 and the second motor 605 on the spiral conveying mechanism 6 move in opposite directions, which in turn drives the first spiral roller 601 and the second spiral roller 602 to move in opposite directions. This allows the sludge entering the sludge hopper 1 to be stirred again, forming an emulsion, which is convenient for the sludge pump 2 to extract the sludge.

[0049] Inside the dredging bucket 1, below the screw conveyor mechanism 6, a mud-water chamber 107 is formed. The dredging hose 201 extends into the mud-water chamber 107. The silt forming an emulsion is drawn into the mud-water chamber 107 by the screw conveyor mechanism 6. The dredging pump 2 is used to extract the silt inside the mud-water chamber 107. The dredging pump 2, which is connected to the dredging bucket 1, pumps the silt inside the mud-water chamber 107 into the mud-water separation box 3. The mud-water separation box 3 has a separation chamber 301. The upper part of the inner side of the separation chamber 301 is connected to a drain pipe 306. Due to the greater weight of the mud in the mud-water, the water is concentrated in the upper part of the mud-water separation box 3 and is discharged back into the river channel through the drain pipe 306. A sludge discharge port 303 is opened on one side of the bottom side of the separation chamber 301. The bottom of the sludge discharge port 303 is connected to a sludge discharge bucket 302. The accumulated silt will be discharged from the sludge discharge bucket 302 to the riverbank.

[0050] Therefore, the present invention can stir solid sludge into a turbid liquid with a relatively high density. After being pumped into the mud-water separation tank 3 by the mud pump 2, the mud and water are separated again to complete the sludge removal process without causing pipe blockage, thus greatly improving the efficiency of sludge removal.

[0051] Furthermore, such as Figure 2 , Figure 3 as well as Figure 4 As shown, a motor support plate 101 and a grid support plate 102 are fixedly installed at the front end of the sludge bucket 1. The cylindrical stirring motor 5 is fixedly installed on the motor support plate 101 by a cylindrical motor fixing ring 501. A grid upper rod 103 is fixedly installed on the grid support plate 102. A grid lower rod 104 is fixedly installed directly below the cylindrical stirring motor 5 between the motor support plates 101. Both the grid upper rod 103 and the grid lower rod 104 are fixed on the sludge bucket 1, improving the overall structural strength. The sludge crushing teeth 502 are arc-shaped. Therefore, multiple arc-shaped grids 105 are fixedly installed between the straight cylinder stirring motor 5 and the screw conveyor 6. Several arc-shaped grids 105 are evenly distributed on the upper grid rod 103 or the lower grid rod 104. Each sludge crushing tooth 502 is set between every two arc-shaped grids 105. This does not affect the normal rotation of the straight cylinder stirring motor 5, but can also turn and stir the sludge. At the same time, it can dig the sludge into the interior of the sludge dredging bucket 1. The structure is simple and improves the efficiency of sludge dredging.

[0052] Meanwhile, hard impurities can slide off the arc-shaped grid 105 under the action of the sludge crushing teeth 502. In other words, hard objects cannot enter the interior of the sludge hopper 1, which can prevent the sludge pump 2 from being damaged and extend the service life of the device.

[0053] In addition, a drive shaft 603 is fixedly connected to both the first spiral roller 601 and the second spiral roller 602. The drive shaft 603 is connected to the output end of the first motor 604 or the second motor 605. The output ends of the first motor 604 and the second motor 605 are both fixedly equipped with the drive shaft 603. The first spiral roller 601 and the second spiral roller 602 are both fixed on the drive shaft 603. The first spiral roller 601 and the second spiral roller 602 rotate in opposite directions. On the one hand, the sludge can be rolled into the interior of the mud and water tank 107. On the other hand, large particles in the sludge can be crushed, improving the extraction efficiency and extending the service life of the device.

[0054] A motor housing 106 is fixedly installed at the end of the sludge hopper 1 away from the straight cylinder stirring motor 5. The first motor 604 or the second motor 605 is fixedly installed inside the motor housing 106 through the motor fixing plate 606. The first motor 604 and the second motor 605 are fixedly installed inside the motor housing 106 to prevent water from entering the first motor 604 or the second motor 605 and to improve their service life.

[0055] Furthermore, such as Figure 6 , Figure 7 as well as Figure 8 As shown, a filter screen slot 304 is provided on one side of the mud-water separation tank 3. A permeable hole 305, connected to the drain pipe 306, is provided on the filter screen slot 304. Since a certain pressure is required when the mud pump 2 extracts the mud and water from the mud-water chamber 107, after the water is pumped into the separation chamber 301, it enters the drain pipe 306 through the permeable hole 305 and is then discharged back into the river, reducing water waste. A filter screen 7 is slidably installed inside the filter screen slot 304, separating the mud and water... A separation box sealing cover 307 is fixedly installed at the port of the separation box 3. Filter screen slide bars 701 are fixedly installed on both sides of the filter screen 7. The filter screen slide bars 701 are slidably installed inside the filter screen slot 304. The filter screen 7 can effectively filter other impurities to prevent the drain pipe 306 from being blocked. At the same time, it can effectively intercept mud and improve the dredging effect. The filter screen slide bars 701 on the filter screen 7 can slide directly inside the filter screen slot 304, so the filter screen 7 can be replaced.

[0056] The sediment accumulates inside the separation chamber 301. A straight-tube sludge discharge motor 8 is rotatably installed at the connection between the sludge discharge port 303 and the sludge discharge hopper 302. Several evenly distributed scraper blades 801 are provided on the outer side of the straight-tube sludge discharge motor 8. After the straight-tube sludge discharge motor 8 is started, the scraper blades 801 on the straight-tube sludge discharge motor 8 scrape the direction of the sediment discharge port 303, thereby discharging the sediment through the sludge discharge hopper 302 onto the riverbank.

[0057] Furthermore, such as Figure 9As shown, the robotic arm 4 includes a vertical support arm 401 and a horizontal support arm 402. The horizontal support arm 402 includes a right-angle connecting arm 407 and a third hydraulic pump 409. The bottom of the third hydraulic pump 409 is fixedly connected to the tractor. The horizontal support arm 402 is directly fixed to the tractor via the third hydraulic pump 409, which can drive the movement of the robotic arm 4. The output end of the third hydraulic pump 409 is fixedly connected to one end of the right-angle connecting arm 407. The height of the right-angle connecting arm 407 can be adjusted via the third hydraulic pump 409, thereby adjusting the overall height of the robotic arm 4. The other end of the right-angle connecting arm 407 is connected to a second hydraulic pump 408. The right-angle connecting arm 407 is fixedly connected to the output end of the second hydraulic pump 408. The other end of the second hydraulic pump 408 is fixedly connected to a horizontal connecting rod 410. In addition, the second hydraulic pump 408 can extend the overall length of the robotic arm 4, which can expand the dredging range and retract the robotic arm 4 onto the tractor for easy transportation.

[0058] The vertical support arm 401 includes a sludge bucket fixing block 405 and a connecting block 404. The bottom of the sludge bucket fixing block 405 is fixedly mounted on the upper side of the sludge bucket 1. The sludge bucket 1 is fixed to the robotic arm 4 via the sludge bucket fixing block 405, improving the stability of the robotic arm 4. The top of the first hydraulic pump 406 is connected to a vertical connecting rod 403. The upper end of the vertical connecting rod 403 is fixedly connected to the connecting block 404. The sludge bucket fixing block 405 is fixedly connected to the output end of the first hydraulic pump 406. The height of the sludge bucket 1 can be lowered by the first hydraulic pump 406, increasing the sludge removal range. The horizontal connecting rod 410 is fixedly connected to one side of the connecting block 404, improving the overall stability of the robotic arm 4. Specifically, during transportation:

[0059] The first hydraulic pump 406 lifts the sludge bucket 1, then the third hydraulic pump 409 lifts the robotic arm 4, and finally the second hydraulic pump 408 retracts the sludge bucket 1 onto the tractor.

[0060] In this embodiment, as Figure 9 and Figure 10 As shown, a hose support rod 9 is fixedly connected to the second hydraulic pump 408 by a support rod screw 902. A hose fixing ring 901 is fixedly installed at one end of the hose support rod 9. The sludge suction hose 201 is installed inside the hose fixing ring 901. When the sludge pump 2 draws mud and water from the sludge dredging bucket 1 through the sludge suction hose 201, the sludge suction hose 201 will be subjected to a certain tension. Therefore, fixing the sludge suction hose 201 to the robotic arm 4 by the hose support rod 9 can improve the stability of the sludge suction hose 201.

[0061] Similarly, the bottom of the mud pump 2, the mud-water separation tank 3, and the robotic arm 4 are all fixedly connected to the assembly plate 10. The assembly plate 10 has several evenly distributed assembly holes 11. The assembly plate 10 is fixedly connected to the tractor by bolts passing through the assembly holes 11. The mud pump 2, the mud-water separation tank 3, and the robotic arm 4 are fixed to the tractor by bolts passing through the assembly holes 11 on the assembly plate 10, thereby improving the overall stability.

[0062] like Figures 1-10 As shown in this embodiment, the dredging method of the onshore towing-type hydraulic dredging device includes the following steps:

[0063] Step 1: Fix the robotic arm. Fix the robotic arm 4, mud pump 2 and mud-water separation box 3 to the tractor vehicle using the assembly plate 10. Use the tractor vehicle to pull the device to the appropriate position on the riverbank.

[0064] Step 2: Adjusting the sludge bucket. The horizontal and vertical positions of the sludge bucket 1 are adjusted by the first hydraulic pump 406, the second hydraulic pump 408 and the third hydraulic pump 409 on the robotic arm 4, and the sludge bucket 1 is then inserted into the sludge.

[0065] Step 3: The dredging bucket is braked. The straight-tube stirring motor 5 drives the silt crushing teeth 502 to break up the silt in the riverbed. Then the silt enters the interior of the dredging bucket 1 and is further stirred by the screw conveyor mechanism 6.

[0066] Step 4: Sludge extraction. Start the sludge pump 2 and extract the sludge from inside the sludge-water tank 107 through the sludge extraction hose 201, and send it into the sludge-water separation tank 3.

[0067] Step 5: Mud-water separation. Under the action of mud-water separation box 3, mud and water are separated. After being separated from mud-water separation box 3, water is discharged into the river through drain pipe 306, and silt is discharged to the bank through sludge discharge bucket 302.
