Abstract
Description
Technical Field
[0001] This utility model relates to the field of garden maintenance technology, and in particular to a multifunctional drainage ditch cleaning device for gardens and land reclamation. Background Technology
[0002] In landscaping and land management, the proper functioning of drainage ditches is crucial, as they effectively remove excess water and prevent waterlogging from damaging plants and the soil. However, over time, drainage ditches can accumulate silt and debris, leading to poor drainage and impairing their normal function.
[0003] Traditional methods of cleaning drainage ditches mainly rely on manual labor using simple tools such as shovels and brooms. This method is not only inefficient and labor-intensive, but also yields unsatisfactory cleaning results. For some deeper drainage ditches, manual cleaning poses significant safety hazards.
[0004] Later, some mechanical cleaning equipment emerged, but these devices had limited functionality. Some could only agitate the silt in the drainage ditch and could not effectively remove it; others could flush but could not clean the inner walls of the drainage ditch; and most of these devices could not be flexibly adjusted according to the width of the drainage ditch, making them poorly adaptable.
[0005] To address the aforementioned problems, this utility model document proposes a multifunctional drainage ditch cleaning device for landscaping and land remediation. Utility Model Content

[0011] A rotating tube rotatably extends through the interior of the support frame and both sides of the first mounting bracket;
[0012] Two sets of blades are fixedly installed on the outer wall of the rotating tube;
[0013] Multiple first nozzles and one second nozzle, the multiple first nozzles are disposed between two sets of blades and communicate with the rotating tube, and the second nozzle is fixedly connected to one end of the rotating tube;
[0014] A cleaning assembly, comprising two cleaning brush handles disposed on both sides of a support frame;
[0015] A drive assembly for driving the rotating tube to rotate and adjusting the spacing between the two cleaning brush arms;
[0016] The blades rotate to break up the silt, the first and second nozzles spray water to rinse and remove the silt, and the cleaning brush cleans the inner wall of the drainage ditch.
[0017] In one possible design, the cleaning assembly includes a second mounting bracket fixed to the top of a first mounting bracket. The top of the second mounting bracket has a first groove, in which a first slider is slidably connected. Second grooves are provided in the extensions on both sides of the second mounting bracket, in which second sliders are slidably connected. A cleaning brush rod is fixed to the bottom of a rotating rod, the top of which rotatably passes through the second slider. A rotating shaft is rotatably mounted on the top of the first slider, and two connecting plates are sleeved on the outer wall of the rotating shaft. The other end of each connecting plate is rotatably connected to the outer wall of the rotating rod. When the first slider moves, the connecting plates drive the second slider to slide, thereby adjusting the spacing between the cleaning brush rods.
[0018] In one possible design, the cleaning assembly further includes multiple second synchronous pulleys, which are arranged in pairs. One pair is fixed to the outer wall of the rotating rod, and the other pair is fixed to the outer wall of the rotating shaft. The same pair is connected by a second synchronous belt. A second motor is fixed to the top of the first slider, and the output shaft of the second motor is connected to the rotating shaft to drive the cleaning brush rod to rotate.
[0019] In one possible design, the drive assembly includes a first motor and an electromagnetic clutch fixed to the bottom of a first mounting bracket. The output shaft of the first motor is connected to the input shaft of the electromagnetic clutch. The output main shaft of the electromagnetic clutch is fixed to a second pulley. The outer wall of the rotating tube is fixed to the first pulley. The first pulley and the second pulley are connected by a belt drive.
[0020] In one possible design, the screw is rotatably extended through one side of the second mounting bracket, and the output shaft of the electromagnetic clutch is connected to the screw via the first synchronous pulley and the first synchronous belt; a fixing block is threaded onto the outer wall of the screw, and the fixing block is fixed to the bottom of the first slider to provide power for adjusting the spacing of the cleaning brush rods.
[0021] In one possible design, a connecting box is fixed on one side of the first mounting bracket, and one end of the rotating tube is sealed and rotates through the connecting box. A water supply pipe is fixed on the outer wall of the connecting box, and the water supply pipe is connected to an external water supply assembly to supply water to the rotating tube.
[0022] In one possible design, multiple mounting blocks are fixed on both sides of the second mounting bracket, and mounting holes are provided in the mounting blocks for mounting with external drive equipment.
[0023] In one possible design, the inner diameter of the plurality of circular frames tapers toward the end away from the second nozzle, forming a conical structure at one end of the support frame; the blades and the first nozzle are located within the gaps between the circular frames; the first nozzle faces toward the end of the support frame closer to the second nozzle.
[0024] In one possible design, the conical structure of the support frame extends deep into the silt, and the blades and the first nozzle contact the silt within the gap. The first nozzle and the second nozzle cooperate to directionally flush the silt.
[0025] In this application, during use, the operator can fix the device to the external drive vehicle body using bolts and mounting blocks, while simultaneously connecting the water supply pipe to the external water supply system. The operator can then place the device into the drainage ditch to be cleaned and start the equipment. At this time, the first motor drives the second pulley to rotate via an electromagnetic clutch, and through belt transmission, drives the first pulley and the rotating pipe to rotate continuously. Two sets of blades fixed on the rotating pipe rotate accordingly, agitating and breaking up the silt in the drainage ditch. Simultaneously, external water enters the rotating pipe through the water supply pipe and connecting box, and high-pressure water jets are sprayed from multiple first nozzles facing the ditch outlet and second nozzles at the end, flushing the broken silt out of the ditch. The conical structure at the front end of the support frame facilitates deep penetration into the siltation area, and the blades and multiple first nozzles are located in the gaps of the circular frame, ensuring full contact with the silt. The device is then gradually moved within the drainage ditch to complete the gradual cleaning of the silt.
[0026] During operation, the operator can adjust the distance between the two cleaning brush rods to ensure they fit snugly against the inner walls of the drainage ditch. During adjustment, the operator controls the electromagnetic clutch to make its output shaft rotate synchronously with the main output shaft. This, via the first synchronous pulley and first synchronous belt, drives the screw to rotate. The fixed block, threadedly connected to the screw, pushes the first slider along the first groove. During the displacement of the first slider, the rotating shaft pulls the two connecting plates, forcing the two second sliders to slide in opposite directions within their respective second grooves, thus achieving synchronous adjustment of the distance between the two cleaning brush rods. Simultaneously, the second motor starts, its output shaft driving the two rotating rods via the rotating shaft, second synchronous pulley, and second synchronous belt, rotating the cleaning brush rods to scrub away any deposits on the inner walls of the drainage ditch.
[0027] This process achieves simultaneous operation of crushing, rinsing, and scrubbing functions. The spacing between the cleaning brushes can adapt to different groove widths, and the device can continuously clean the groove while moving.
[0028] Beneficial effects: The multifunctional drainage ditch cleaning device for garden and land management described in this utility model can simultaneously break up and flush out silt by rotating blades and spraying flushing water with multiple first nozzles and end second nozzles; the cleaning brush can scrub the attached materials on the ditch wall. A single device can complete the whole process of crushing, flushing and scrubbing, which can significantly improve the work efficiency.
[0029] In this utility model, a multifunctional drainage ditch cleaning device for gardens and land management is described. By driving the first slider to move along the chute, the two second sliders are forced to slide in opposite directions through the transmission of the connecting plate, which can drive the cleaning brush rod to adjust the spacing synchronously. This design allows the brush rod to fit closely to the sidewalls of drainage ditches of different widths, making it easy to adapt to various working conditions.
[0030] In this utility model, a multifunctional drainage ditch cleaning device for garden and land management is described. The first motor distributes power through an electromagnetic clutch: the output main shaft drives the rotating tube and blades to rotate through belt transmission; the output sub-shaft drives the screw to rotate through a synchronous belt, and pushes the fixed block and the first slider to move through the thread, providing power for brush bar spacing adjustment; a single motor can control the core operation and adjustment functions, reducing energy consumption and structural complexity.
[0031] In this utility model, the multifunctional drainage ditch cleaning device for gardens and land remediation has a front end of a support frame with a tapered inner diameter, which facilitates deep penetration into siltation areas; the blades and the first nozzle are set in the gap of the circular frame to ensure full contact with the silt; and multiple nozzles are all oriented towards the ditch outlet, which can enhance the directional flushing effect on the silt.
[0032] In this utility model, the multifunctional drainage ditch cleaning device for garden and land management has a mounting block on the side of the mounting frame that is easy to fix to an external drive vehicle; the water supply pipe can be conveniently and continuously supplied to the rotating pipe through the connecting box to ensure flushing pressure; the synchronous pulley and synchronous belt drive can ensure the stable rotation of the brush rod and ensure effective scrubbing and cleaning of the inner wall of the drainage ditch.
[0033] In this invention, the device uses rotating blades to break up silt, which is then flushed out by nozzles facing the ditch opening. Simultaneously, rotating brushes clean the ditch walls. A single unit integrates crushing, flushing, and scrubbing functions. The brush spacing is adjusted via a slider-connecting plate linkage mechanism to accommodate different ditch widths. A single motor distributes power via an electromagnetic clutch, with its main shaft driving the blades to rotate. The secondary shaft controls the brush spacing adjustment via a synchronous belt-screw mechanism, reducing energy consumption and cost. The conical support frame facilitates deep penetration into the siltation area, and the blades and nozzles are positioned in the frame gap to ensure full contact with the silt. The overall structure ensures effective cleaning of siltation inside the drainage ditch. Attached Figure Description

Detailed Implementation
[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0041] In one embodiment: Refer to Figure 1-5 A cleaning device includes: a support frame 1, blades 6, a nozzle, a cleaning component, and a drive component.
[0042] In this embodiment, the support frame 1 is composed of multiple circular frames that are sequentially and fixedly connected, resulting in a stable overall structure. A first mounting bracket 2 is provided on the outside of the support frame 1, with both ends of the support frame 1 fixedly connected to the inner walls of the first mounting bracket 2 on both sides, ensuring stable installation of the support frame 1 on the first mounting bracket 2. A rotating tube 3 rotatably passes through the inside of the support frame 1, with both ends of the rotating tube 3 rotatably passing through both sides of the first mounting bracket 2, providing a foundation for the installation and rotation of subsequent components.
[0043] In this embodiment, two sets of blades 6, multiple first nozzles 7, and one second nozzle 8 are installed on the rotating pipe 3. Both sets of blades 6 are fixedly installed on the outer wall of the rotating pipe 3. When the rotating pipe 3 rotates, the blades 6 rotate accordingly, breaking up the silt in the drainage ditch. Multiple first nozzles 7 are positioned between two blades 6 and are fixedly connected to the rotating pipe 3. The second nozzle 8 is fixedly connected to one end of the rotating pipe 3. Water is supplied to the rotating pipe 3 through an external water supply assembly, and water is sprayed from the first nozzles 7 and the second nozzle 8 to flush and discharge the broken-up silt.
[0044] In this embodiment, the cleaning assembly is used to clean the inner walls of both sides of the drainage ditch. The cleaning assembly includes a second mounting bracket 15 fixedly installed on the top of the first mounting bracket 2. The top of the second mounting bracket 15 has a first sliding groove 16, and a first slider 21 is slidably installed inside the first sliding groove 16. The extensions on both sides of the second mounting bracket 15 have second sliding grooves 17, and a second slider 23 is slidably connected inside each of the two second sliding grooves 17. Two cleaning brush rods 25 are located at the bottom of the two second sliders 23. A rotating rod 24 is fixedly installed on the top of each cleaning brush rod 25, and the top of the rotating rod 24 rotatably passes through the adjacent second slider 23. A rotating shaft 20 is rotatably installed on the top of the first slider 21. Two connecting plates 26 are rotatably sleeved on the outer wall of the rotating shaft 20, and the other ends of the two connecting plates 26 are rotatably connected to the outer wall of the corresponding rotating rod 24. When the first slider 21 moves within the first slide groove 16, the two second sliders 23 slide within the corresponding second slide groove 17 via the transmission of the two connecting plates 26, thereby changing the distance between the two cleaning brush rods 25 to adapt to drainage ditches of different widths.
[0045] In this embodiment, to achieve continuous driving rotation of the two cleaning brush rods 25, multiple second synchronous pulleys 27 are also provided in the cleaning assembly. The multiple second synchronous pulleys 27, rotatably mounted on the tops of the two connecting plates 26, are arranged in pairs, with the two second synchronous pulleys 27 in the same pair located near the ends of the corresponding connecting plates 26. Of the two second synchronous pulleys 27 in the same pair, one is fixedly sleeved on the outer wall of the corresponding rotating rod 24, and the other is fixedly sleeved on the outer wall of the rotating shaft 20. The two second synchronous pulleys 27 in the same pair are connected by a corresponding second synchronous belt. A second motor 19 is fixedly mounted on the top of the first slider 21 via a bracket, and one end of the output shaft of the second motor 19 is fixedly connected to the rotating shaft 20. Starting the second motor 19 drives the rotating shaft 20 to rotate. Through the transmission of the second synchronous pulleys 27 and the second synchronous belt, the rotating rod 24 and the cleaning brush rods 25 can rotate, thereby cleaning the inner walls on both sides of the drainage ditch.
[0046] In this embodiment, the drive assembly is used to drive the rotating tube 3 to rotate continuously, and can also drive the two cleaning brush rods 25 to adjust the distance between them. The drive assembly includes a first motor 10 and an electromagnetic clutch 11 fixedly installed on the inner wall of the bottom of the first mounting bracket 2. One end of the output shaft of the first motor 10 is fixedly connected to one end of the input shaft of the electromagnetic clutch 11. One end of the output shaft of the electromagnetic clutch 11 is fixedly connected to a second pulley 12. A first pulley 9 is fixedly sleeved on the outer wall of the rotating tube 3. The first pulley 9 and the second pulley 12 are connected by a belt drive. When the first motor 10 is started, power is transmitted to the second pulley 12 through the electromagnetic clutch 11, and then the belt drives the first pulley 9 and the rotating tube 3 to rotate, realizing the movement of the blades 6 and the nozzle.
[0047] In this embodiment, a screw 14 is rotatably inserted through one side of the second mounting bracket 15. The output shaft of the electromagnetic clutch 11 is connected to one end of the screw 14 via a corresponding first synchronous pulley and a first synchronous belt 13, enabling the electromagnetic clutch 11 to control the screw 14. A fixing block 22 is threaded onto the outer wall of the screw 14, and the fixing block 22 is fixedly connected to the bottom of the first slider 21. When the electromagnetic clutch 11 controls the screw 14 to rotate, the screw 14 drives the fixing block 22 and the first slider 21 to move, thereby adjusting the distance between the two cleaning brush rods 25.
[0048] In this embodiment, a connecting box 4 is fixedly installed on one side of the first mounting bracket 2, and one end of the rotating tube 3 is sealed and rotates through one side of the connecting box 4. A water supply pipe 5 is fixedly connected to the outer wall of the connecting box 4. The water supply pipe 5 is connected to an external water supply component to realize continuous water supply to the rotating tube 3 and ensure that the nozzle has sufficient water pressure for sludge flushing.
[0049] This application can be used in the field of landscape maintenance technology, or in other fields applicable to this application.
[0050] In another embodiment: Reference Figure 1 , 2 4. A multi-functional drainage ditch cleaning device for gardens and land management, which is applied to the field of garden maintenance technology.
[0051] In this embodiment, multiple mounting blocks 18 are fixedly installed on both sides of the second mounting frame 15. Each mounting block 18 has a corresponding mounting hole. Through these mounting holes, the device can be easily installed and combined with external driving equipment (such as a tractor or other driving vehicle), which facilitates the movement and use of the device in landscaping and land reclamation work.
[0052] In this embodiment, the inner diameter of the multiple circular frames gradually decreases toward the end away from the second nozzle 8, so that one end of the support frame 1 forms a conical structure. This structure can ensure that the support frame 1 can fully penetrate into the silt when cleaning the drainage ditch.
[0053] In this embodiment, the two sets of blades 6 and the multiple first nozzles 7 are all located in the gap between the two circular frames to ensure full contact with the sludge. The multiple first nozzles 7 are all oriented towards the end of the supporting frame 1 closest to the second nozzle 8 to thoroughly flush the sludge and improve the cleaning effect.
[0054] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 10, the electromagnetic clutch 11, and the second motor 19 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0055] The working principle and usage process of this technical solution are as follows: During use, the operator can fix the device to the external drive vehicle body using bolts and mounting block 18, while the water supply pipe 5 is connected to the external water supply system. The operator can then place the device into the drainage ditch to be cleaned and start the equipment. At this time, the first motor 10 drives the second pulley 12 to rotate via the electromagnetic clutch 11, which, after belt transmission, drives the first pulley 9 and the rotating pipe 3 to rotate continuously. The two sets of blades 6 fixed on the rotating pipe 3 rotate accordingly, agitating and dispersing the silt in the drainage ditch. Simultaneously, external water enters the rotating pipe 3 through the water supply pipe 5 and connecting box 4, and high-pressure water jets are sprayed from multiple first nozzles 7 facing the ditch outlet and second nozzles 8 at the end, flushing the dispersed silt out of the ditch. The conical structure at the front end of the support frame 1 facilitates deep penetration into the siltation area, and the blades 6 and multiple first nozzles 7 are located in the gaps of the circular frame, ensuring full contact with the silt. The device is then gradually moved in the drainage ditch to complete the gradual cleaning of the silt in the ditch.
[0056] During equipment use, the operator can adjust the distance between the two cleaning brush rods 25 to ensure they fit snugly against the inner walls of the drainage ditch. During adjustment, the operator controls the electromagnetic clutch 11 to make its output shaft rotate synchronously with the output main shaft. This, in turn, drives the screw 14 to rotate via the first synchronous pulley and the first synchronous belt 13. The fixed block 22, threadedly connected to the screw 14, pushes the first slider 21 to move along the first slide groove 16. During the displacement of the first slider 21, the rotating shaft 20 pulls the two connecting plates 26, thereby forcing the two second sliders 23 to slide in opposite directions within their respective second slide grooves 17, thus achieving synchronous adjustment of the distance between the two cleaning brush rods 25. Simultaneously, the second motor 19 starts, and its output shaft, via the rotating shaft 20, the second synchronous pulley 27, and the second synchronous belt, drives the two rotating rods 24 to rotate the cleaning brush rods 25, thus scrubbing away any deposits on the inner walls of the drainage ditch.
[0057] This process achieves simultaneous operation of crushing, rinsing, and scrubbing functions. The 25mm spacing of the cleaning brush rods can adapt to different groove widths, and the device can continuously clean the groove while moving.
[0058] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
