Technical Field

[0001] This invention relates to the field of drainage ditch dredging technology, specifically to a road drainage ditch dredging device and its dredging method. Background Technology

[0002] Drainage ditch dredging refers to the process of removing silt, garbage, leaves, gravel, grease, and other blockages deposited on the bottom and sides of various drainage ditches (including rainwater ditches, sewage ditches, combined sewer ditches, roadside ditches, riverbank drainage ditches, etc.) by manual or mechanical means. In the current construction process, due to the different locations of the drainage ditch blockages and the limitation of the length of the dredging equipment itself, workers need to frequently disassemble and install the equipment and open the manhole covers at the blockage locations, which is not only time-consuming and labor-intensive, but also has low dredging efficiency.

[0016] A further improvement of the technical solution of the present invention is that: the side of the outer wall of the extension frame away from the dredging body is in contact with an installation block, and the side of the inner wall of the installation block near the extension frame is slidably connected to the outer wall of the first limiting block, and one side of the inner wall of the installation block penetrates the outer wall of the guide pipe near the high-pressure rotating nozzle, the bottom of the guide pipe is in contact with an auxiliary frame, and the bottom of the auxiliary frame is fixedly connected to the top of one side of the inner wall of the extension frame.

[0017] A method for dredging road drainage ditches, using the aforementioned road drainage ditch dredging device, is as follows:

[0018] S1: By setting insert blocks on both sides of the outer wall of the dredging body, and then installing corresponding size card plates on both sides of the outer wall of the insert blocks, the dredging body is placed in the drainage ditch, so that one end of the card plate is at the top of the drainage ditch. Then, several assembly blocks are continuously put into the dredging body, and the extension component set on the top of the extension frame is activated, so that the assembly blocks continuously push the installation block, the guide pipe and the high-pressure rotating nozzle to move in the drainage ditch. The water flow sprayed by the high-pressure rotating nozzle is used to clean the silt in the drainage ditch.

[0019] S2: The extension assembly has control boxes set on both sides of the outer wall of the extension frame, and a sealing block is set on one side of the inner wall of the control box. The micro motor set in the inner cavity of the sealing block is started, which drives the transmission rod set at the output end. The transmission rod drives the transmission gear rod through the synchronous belt, so that the transmission gear rod pushes the assembly block to move continuously on the surface of the extension frame through the tooth marks set on the outer wall of the assembly block.

[0020] S3: By setting first limiting blocks at both ends on one side of the outer wall of the assembly block, and setting a first limiting groove on the side of the outer wall of the assembly block away from the first limiting blocks, when the newly added assembly block enters the dredging body, the first limiting block is embedded in the first limiting groove.

[0021] S4: By setting a first groove at one end of the inner cavity of the assembly block near the first limiting block, and setting a first slider on the inner wall of the first groove, when the assembly block moves down continuously, the stabilizing block set on one side of the outer wall of the first slider contacts the surface of the assembly block and is put into the first groove. By setting a stabilizing groove at one end of the inner cavity of the assembly block away from the first groove, when the first limiting block is fully inserted into the first limiting groove, the first elastic telescopic rod set on the side of the first slider away from the stabilizing block is used to push the first slider to move in the first groove, and the stabilizing block is inserted into the stabilizing groove, thus completing the splicing of the assembly block.

[0022] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0023] 1. This invention provides a road drainage ditch dredging device and its dredging method. The device uses toothed grooves to push the assembly block and installation block to slide on the surface of the extension frame and slowly move away from the traction block. During this time, the installation block pushes the high-pressure rotating nozzle and the guide pipe to move synchronously. Simultaneously, a water pump is activated, and high-pressure water is sent through the guide pipe into the high-pressure rotating nozzle to flush away the silt in the drainage ditch. The water, mixed with silt and impurities, flows down the bottom of the drainage ditch and is discharged through the gap between the dredging body and the drainage ditch. This further solves the problem that traditional road drainage ditch dredging devices often require workers to remove the corresponding manhole covers when facing long-distance blockages due to the lack of support in existing pipe dredging devices. This not only involves a large workload but also results in low dredging efficiency.

[0024] 2. This invention provides a road drainage ditch dredging device and its dredging method. A first limiting block, located on one side of the outer wall of the assembly block within the dredging body, is inserted into a first limiting groove on one side of the outer wall of the assembly block on the surface of the extension frame. As the assembly block continues to move downwards, a stabilizing block located at the end of the outer wall of the first slider away from the first elastic telescopic rod comes into contact with the surface of the assembly block. With continuous compression, the inclined surface of the stabilizing block, under the influence of a downward pushing force, moves into a first sliding groove along with the first slider. When the assembly block contacts the top of the extension frame, the rebound force of the first elastic telescopic rod pushes the first slider and the stabilizing block together into the stabilizing groove within the inner cavity of the assembly block, which comes into contact with it. This further solves the problem that traditional road drainage ditch dredging devices, due to their limited extendable length, require frequent disassembly and relocation to a suitable position for reinstallation.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 10As shown in the embodiment of the present invention, a road drainage ditch dredging device includes a dredging body 1 and a drainage ditch 2. Insert blocks 3 are fixedly connected to both sides of the outer wall of the dredging body 1, and a clamping plate 4 is slidably connected to the outer wall of the insert blocks 3. The outer wall of the clamping plate 4 contacts the inner wall of the drainage ditch 2. A traction block 5 is fixedly connected to one side of the outer wall of the dredging body 1, and a guide pipe 6 is slidably connected to the inner cavity of the traction block 5. A high-pressure rotating nozzle 7 is fixedly connected to one end of the guide pipe 6. An extension frame 8 is fixedly connected to the bottom of one side of the inner wall of the dredging body 1, and an extension assembly is slidably connected to the top of the extension frame 8. The extension assembly includes several sets of components slidably connected to the top of the extension frame 8. Assembly block 9 is provided, and two ends of one side of the outer wall of assembly block 9 are fixedly connected to first limiting blocks 10. A first limiting groove 11 is formed on the side of the outer wall of assembly block 9 away from the first limiting blocks 10. A first sliding groove 12 is formed at the end of the inner cavity of assembly block 9 near the first limiting blocks 10, and a stabilizing groove 13 is formed at the end of the inner cavity of assembly block 9 away from the first sliding groove 12. A first slider 14 is slidably connected to the inner wall of the first sliding groove 12, and a hook 15 is fixedly connected to the top of the first slider 14. A first elastic telescopic rod 16 is fixedly connected to both ends of one side of the outer wall of the first slider 14, and one end of the first elastic telescopic rod 16 is slidably connected to the inner cavity of assembly block 9. A stabilizing block 17 is fixedly connected to the end of the outer wall of a slider 14 away from the first elastic telescopic rod 16. Control boxes 18 are fixedly connected to both sides of the outer wall of the extension frame 8. A sealing block 19 is fixedly connected to one side of the inner wall of the control box 18. A micro motor 20 is fixedly connected to the inner cavity of the sealing block 19. A transmission rod 21 is fixedly connected to the output end of the micro motor 20. The end of the transmission rod 21 away from the micro motor 20 is rotatably connected to the top of the inner wall of the control box 18. One side of the outer wall of the transmission rod 21 penetrates the top of the inner cavity of the sealing block 19. A synchronous belt 23 is drively connected to the side of the outer wall of the transmission rod 21 near the top of the control box 18. The two sides of the synchronous belt 23... The end drive is connected to a transmission gear rod 24, and both ends of the transmission gear rod 24 are rotatably connected to the inner wall of the control box 18. The outer walls of the assembly block 9 are provided with tooth marks 25 on both sides, and the inner walls of the tooth marks 25 mesh with the outer walls of the transmission gear rod 24. The side of the outer wall of the extension frame 8 away from the dredging body 1 contacts the mounting block 41, and the inner wall of the mounting block 41 near the extension frame 8 is slidably connected to the outer wall of the first limiting block 10. The inner wall of the mounting block 41 penetrates the outer wall of the guide pipe 6 near the high-pressure rotating nozzle 7. The bottom of the guide pipe 6 contacts the auxiliary frame 22, and the bottom of the auxiliary frame 22 is fixedly connected to the top of one side of the inner wall of the extension frame 8.

[0038] During operation, an extension frame 8 is installed at the bottom of one side of the inner wall of the dredging body 1, and several assembly blocks 9 are placed on the surface of the extension frame 8. Since the two ends of one side of the outer wall of the assembly block 9 are provided with first limiting blocks 10, and the side of the outer wall of the assembly block 9 away from the first limiting blocks 10 is provided with a corresponding number of first sliding grooves 12, the first limiting blocks 10 are inserted into the first limiting grooves 11, so that several assembly blocks 9 are spliced ​​and fixed together. Then, the assembly block 9 at the top of the extension frame 8 away from the dredging body 1 is assembled with the mounting block 41, and the first limiting blocks 10 are inserted into the mounting block 41 to fix it. Then, the guide pipe 6 connected to the water pump passes through the traction block 5 provided on one side of the outer wall of the dredging body 1 and is placed on the auxiliary pipe provided at the top of the inner wall of the extension frame 8. On the surface of the auxiliary frame 22, the guide pipe 6 passes through the mounting block 41. At this time, the input end of the high-pressure rotary nozzle 7 (the high-pressure rotary nozzle 7 is existing technology) is connected to the end of the guide pipe 6 away from the water pump, thus completing the assembly of the dredging body 1. Insert blocks 3 are set on both sides of the outer wall of the dredging body 1, and then the corresponding size clamping plate 4 is installed on both sides of the outer wall of the dredging body 1 along the insert blocks 3. At this time, the manhole cover at the top of the drainage ditch 2 is opened, and the dredging body 1 together with the clamping plate 4 is placed into the drainage ditch 2, so that the protrusion of the clamping plate 4 fits with the two ends of the top of the drainage ditch 2. Then, the clamping plate 4 is fixed with rivets. Control boxes 18 are set on both sides of the outer wall of the extension frame 8, and a sealing block 19 is set on one side of the inner wall of the control box 18. A micro motor 20 is installed inside the cavity of the sealing block 19. Starting the micro motor 20 drives the transmission rod 21 (composed of a support rod and a synchronous pulley, existing technology) at its output end. The transmission rod 21 passes through the top of the cavity of the sealing block 19 and drives the synchronous belt 23 (composed of a V-belt and a synchronous pulley, existing technology) located on its outer wall near the top of the control box 18 to rotate. The synchronous belt 23 then drives the transmission gear rod 24 (composed of a gear and a rotating shaft, existing technology) located at one end of the inner wall of the control box 18 to rotate. Since tooth marks 25 are provided on both sides of the outer wall of the assembly block 9, the rotation of the transmission gear rod 24 pushes the assembly block through the tooth marks 25. Block 9 and mounting block 41 slide on the surface of extension frame 8 and move slowly away from traction block 5. During this period, mounting block 41 pushes high-pressure rotating nozzle 7 and guide pipe 6 to move synchronously. At the same time, water pump is started and high-pressure water is sent into high-pressure rotating nozzle 7 through guide pipe 6 to flush the silt in drainage ditch 2. The water mixed with silt and impurities flows down the bottom of drainage ditch 2 and is discharged through the gap between dredging body 1 and drainage ditch 2. This further solves the problem that in the use of traditional road drainage ditch 2 dredging device, due to the lack of support of existing pipeline dredging device, when facing long-distance blockage areas, construction personnel often need to remove the corresponding manhole cover, which not only has a large workload but also low dredging efficiency.

[0039] It should be further explained that by continuously inserting several assembly blocks 9 into the dredging body 1, and embedding the first limiting block 10 into the guide groove 26 provided on one side of the inner wall of the dredging body 1, the assembly blocks 9 are supported by the wedge-shaped blocks 40 provided at the bottom of both sides of the inner wall of the dredging body 1. Since one end of the inner cavity of the assembly block 9 is provided with a stabilizing groove 13, and the end of the inner cavity of the assembly block 9 away from the stabilizing groove 13 is provided with a first sliding groove 12, a first slider 14 is provided on the inner wall of the first sliding groove 12, and a first elastic telescopic rod 16 is provided at both ends of the outer wall of the first slider 14. The top of the first slider 14 is provided with a hook 15. As the transmission gear rod 24 drives... The assembly block 9 placed on top of the extension frame 8 moves continuously, creating a gap on the side of the extension frame 8 close to the dredging body 1. Simultaneously, the micro motor 20 stops driving, and the teeth on the surface of the transmission gear rod 24 close to the dredging body 1 align with the tooth marks 25 on the surface of the assembly block 9 inside the dredging body 1. At this time, by pressing down on the topmost assembly block 9 on the inner wall of the dredging body 1, the bottommost assembly block 9 presses against the inclined surface of the top of the wedge block 40, causing the wedge block 40 to retract into the reset box 38. This moves the bottommost assembly block 9 to the surface of the extension frame 8, and the tooth marks 25 on its outer wall contact the teeth on the surface of the transmission gear rod 24. During this period, the first limiting block 10, located on one side of the outer wall of the assembly block 9 inside the dredging main body 1, is inserted into the first limiting groove 11, located on one side of the outer wall of the assembly block 9 on the surface of the extension frame 8. As the assembly block 9 continues to move downward, the stabilizing block 17, located at the end of the outer wall of the first slider 14 away from the first elastic telescopic rod 16, comes into contact with the surface of the assembly block 9. With continuous compression, the inclined surface of the stabilizing block 17, under the influence of the downward pushing force, moves into the first sliding groove 12 along with the first slider 14. When the assembly block 9 contacts the top of the extension frame 8, the rebound force of the first elastic telescopic rod 16 pushes the first slider 14 and the stabilizing block 17 together into the groove. Within the stabilizing groove 13 inside the fitted assembly block 9, the above operation is repeated. The micro motor 20 drives the transmission gear rod 24 to push the assembly block 9 towards the mounting block 41, causing the assembly block 9 to detach from the support of the extension frame 8. Under the constraints of the first limiting block 10, the first limiting groove 11, the stabilizing block 17, and the stabilizing groove 13, the assembled assembly block 9 carries the mounting block 41, the guide pipe 6, and the extension frame 8 in a straight line. This further solves the problem that traditional road drainage ditch 2 dredging devices require frequent disassembly and reinstallation in a suitable location due to the limited extension length of the device during use.

[0040] A guide groove 26 is provided on one side of the inner wall of the dredging body 1, and the inner wall of the guide groove 26 is slidably connected to the outer wall of the first limiting block 10. A second limiting groove 27 is provided at the bottom of the outer wall of the dredging body 1 on the side away from the traction block 5. A second limiting block 28 is slidably connected to the inner wall of the second limiting groove 27, and an electric telescopic rod 29 is fixedly connected to the inner cavity of the second limiting block 28. A second slider 30 is fixedly connected to the output end of the electric telescopic rod 29. Both ends of the outer wall of the second slider 30 are slidably connected to the inner wall of the second limiting block 28. Both ends of the bottom of the second slider 30 are provided with cavities 31, and both ends of the inner wall of the cavity 31 are fixedly connected to arc springs 32. A rotating shaft block 33 is rotatably connected to the center of the inner wall of the cavity 31, and both sides of the outer wall of the rotating shaft block 33 are in contact with the outer wall of the arc spring 32. Push rods are fixedly connected to the outer walls of the two rotating shaft blocks 33 on the side away from the cavity 31. 34, and one end of the push rod 34 contacts the outer wall of the hook 15. A limit box 35 is fixedly connected to one side of the outer wall of the control box 18, and the outer wall of the limit box 35 is fixedly connected to the inner cavity of the dredging body 1. An electric screw rod 36 is installed on the inner wall of the limit box 35. A push plate 37 is threadedly connected to the outer wall of the electric screw rod 36, and the outer wall of the push plate 37 is slidably connected to the inner wall of the limit box 35. The top of the push plate 37 contacts the bottom of the assembly block 9. A reset box 38 is fixedly connected to the top of the limit box 35. The outer wall of the reset box 38 is fixedly connected to the end of the inner cavity of the dredging body 1 near the limit box 35. A second elastic telescopic rod 39 is fixedly connected to both ends of the inner cavity of the reset box 38, and a wedge block 40 is fixedly connected to the output end of the second elastic telescopic rod 39. The outer wall of the wedge block 40 is slidably connected to the inner wall of the reset box 38, and the top of the wedge block 40 contacts the bottom of the assembly block 9.

[0041] During operation, a limit box 35 is installed on one side of the outer wall of the control box 18, and an electric lead screw 36 (composed of a lead screw and a motor, which is existing technology) is installed on the inner wall of the limit box 35. A push plate 37 is installed on the outer wall of the electric lead screw 36. When the drainage ditch 2 is dredged and the assembled blocks 9 need to be disassembled and recycled, the electric lead screw 36 is activated, which drives the push plate 37 on its outer wall to move upward within the limit box 35. This causes the push plate 37 to extend out of the limit box 35 and lift the assembled block 9 near the dredging body 1, and causes the first limit block 10 on the outer wall of the assembled block 9 to re-insert into the dredging body 1. Within the guide groove 26 on one side of the inner wall, a second limiting groove 27 is simultaneously provided at the bottom of the outer wall of the dredging body 1 on the side away from the traction block 5, and a second limiting block 28 is provided on the inner wall of the second limiting groove 27. An electric telescopic rod 29 is installed in the inner cavity of the second limiting block 28, causing the electric telescopic rod 29 to push the second slider 30 at the output end to move along the inner wall of the second limiting block 28. Since both ends of the bottom of the second slider 30 are provided with cavities 31, and both ends of the inner wall of the cavity 31 are provided with arc-shaped springs 32, and a rotating shaft block 33 is provided at the center of the inner wall of the cavity 31, a push rod is provided on the outer wall of the rotating shaft block 33 on the side away from the cavity 31. 34. When the second slider 30 moves, it pushes the push rod 34 and the hook 15 set on the top of the first slider 14, causing the stabilizing block 17 to be pushed out of the stabilizing groove 13 and into the first sliding groove 12. This, combined with the push plate 37, causes the first limiting block 10 to disengage from the first limiting groove 11. A reset box 38 is set on the top of the limiting box 35, and second elastic telescopic rods 39 are set at both ends of the inner cavity of the reset box 38. During the ascent of the assembly block 9, the wedge-shaped block 40 set at the output end of the second elastic telescopic rod 39 is squeezed. Since the bottom surface of the wedge-shaped block 40 is also an inclined surface, the wedge-shaped block 40 is pulled into the reset box 38 during the squeezing process. As the assembly block 9 continues to rise and disengage... When the wedge block 40 is restrained, the wedge block 40 pops out again from the reset box 38. At the same time, the stabilizing block 17 is released from the restraint of the assembly block 9 on the surface of the extension frame 8. As the assembly block 9 rises, the push rod 34 gradually releases the pressure on the hook 15 and comes into contact with the surface of the assembly block 9. As the assembly block 9 rises to the top of the electric screw 36 under the push of the push plate 37, the push rod 34 is no longer restrained by the assembly block 9. Under the action of the rebound force of the arc spring 32, the push rod 34 is reset by pushing the rotating shaft block 33. By repeating the above operation, the assembly block 9 is recovered, and the mounting block 41, the guide tube 6 and the high-pressure rotating nozzle 7 are reset.

[0042] A method for dredging road drainage ditches, using the aforementioned road drainage ditch dredging device, is as follows:

[0043] S1: By setting insert blocks 3 on both sides of the outer wall of the dredging body 1, and then installing the corresponding size card plate 4 on both sides of the outer wall of the insert block 3, the dredging body 1 is placed in the drainage ditch 2, so that one end of the top of the card plate 4 is at the top of the drainage ditch 2. Then, several assembly blocks 9 are continuously placed into the dredging body 1, and the extension component set on the top of the extension frame 8 is activated, so that the assembly blocks 9 continuously push the installation block 41, the guide pipe 6 and the high pressure rotating nozzle 7 to move in the drainage ditch 2, and the water flow sprayed by the high pressure rotating nozzle 7 is used to clean the silt in the drainage ditch 2.

[0044] S2: The extension assembly is provided with control boxes 18 on both sides of the outer wall of the extension frame 8, and a sealing block 19 is provided on one side of the inner wall of the control box 18. The micro motor 20 in the inner cavity of the sealing block 19 is started, which drives the transmission rod 21 at the output end. The transmission rod 21 drives the transmission gear rod 24 through the synchronous belt 23, so that the transmission gear rod 24 pushes the assembly block 9 to move continuously on the surface of the extension frame 8 through the tooth marks 25 provided on the outer wall of the assembly block 9.

[0045] S3: By setting first limiting blocks 10 at both ends on one side of the outer wall of assembly block 9, and setting first limiting groove 11 on the side of the outer wall of assembly block 9 away from the first limiting blocks 10, when the newly added assembly block 9 enters the dredging body 1, the first limiting blocks 10 are embedded in the first limiting groove 11.

[0046] S4: By setting a first sliding groove 12 at one end of the inner cavity of the assembly block 9 near the first limiting block 10, and setting a first slider 14 on the inner wall of the first sliding groove 12, when the assembly block 9 moves down continuously, the stabilizing block 17 set on one side of the outer wall of the first slider 14 contacts the surface of the assembly block 9 and is put into the first sliding groove 12. By setting a stabilizing groove 13 at one end of the inner cavity of the assembly block 9 away from the first sliding groove 12, when the first limiting block 10 is fully inserted into the first limiting groove 11, the first elastic telescopic rod 16 set on the side of the first slider 14 away from the stabilizing block 17 is used to push the first slider 14 to move in the first sliding groove 12, and the stabilizing block 17 is inserted into the stabilizing groove 13, thus completing the splicing of the assembly block 9.

[0047] The working principle of the road drainage ditch dredging device and its dredging method will be explained in detail below.

[0048] like Figures 1-10As shown, an extension frame 8 is installed at the bottom of one side of the inner wall of the dredging body 1, and several assembly blocks 9 are placed on the surface of the extension frame 8. Since the two ends of one side of the outer wall of the assembly block 9 are provided with first limiting blocks 10, and the side of the outer wall of the assembly block 9 away from the first limiting blocks 10 is provided with a corresponding number of first sliding grooves 12, the first limiting blocks 10 are inserted into the first limiting grooves 11, so that several assembly blocks 9 are spliced ​​and fixed together. Then, the assembly block 9 at the top of the extension frame 8 away from the dredging body 1 is assembled with the mounting block 41, and the first limiting blocks 10 are inserted into the mounting block 41 to fix it. Then, the guide pipe 6 connected to the water pump passes through the traction block 5 provided on one side of the outer wall of the dredging body 1 and is placed on the auxiliary block provided at the top of the inner wall of the extension frame 8. On the surface of frame 22, the guide pipe 6 passes through the mounting block 41. At this time, the input end of the high-pressure rotary nozzle 7 (which is existing technology) is connected to the end of the guide pipe 6 away from the water pump, thus completing the assembly of the dredging body 1. Insert blocks 3 are set on both sides of the outer wall of the dredging body 1, and then the corresponding size clamping plate 4 is installed on both sides of the outer wall of the dredging body 1 along the insert blocks 3. At this time, the manhole cover at the top of the drainage ditch 2 is opened, and the dredging body 1 together with the clamping plate 4 is placed into the drainage ditch 2, so that the protrusion of the clamping plate 4 fits with the two ends of the top of the drainage ditch 2. Then, the clamping plate 4 is fixed with rivets. Control boxes 18 are set on both sides of the outer wall of the extension frame 8, and a sealing block 19 is set on one side of the inner wall of the control box 18. A micro motor 20 is installed inside the cavity of assembly block 9. Starting the micro motor 20 drives the transmission rod 21 (composed of a support rod and a synchronous pulley, existing technology) at its output end. The transmission rod 21 passes through the top of the cavity of the sealing block 19, causing the synchronous belt 23 (composed of a V-belt and a synchronous pulley, existing technology) located on its outer wall near the top of the control box 18 to rotate. The synchronous belt 23 then drives the transmission gear rod 24 (composed of a gear and a rotating shaft, existing technology) located at one end of the inner wall of the control box 18 to rotate. Since tooth marks 25 are provided on both sides of the outer wall of assembly block 9, the rotation of the transmission gear rod 24 pushes the assembly block through the tooth marks 25. 9 and mounting block 41 slide on the surface of extension frame 8 and move slowly away from traction block 5. During this period, mounting block 41 pushes high-pressure rotating nozzle 7 and guide pipe 6 to move synchronously. At the same time, water pump is started and high-pressure water is sent into high-pressure rotating nozzle 7 through guide pipe 6 to flush the silt in drainage ditch 2. The water mixed with silt and impurities flows down the bottom of drainage ditch 2 and is discharged through the gap between dredging body 1 and drainage ditch 2. This further solves the problem that in the use of traditional road drainage ditch 2 dredging device, due to the lack of support of existing pipeline dredging device, when facing long-distance blockage areas, construction personnel often need to remove the corresponding manhole cover, which is not only labor-intensive but also has low dredging efficiency.

[0049] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
