Description

Technical Field

[0001] This invention relates to the technical field of sludge treatment, and more specifically, to a sludge suction and dredging device for landscaping and its usage method. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to their living environment. Modern communities often build green belts between buildings, and some even have specially designated garden areas, some of which include ponds. Over time, silt accumulates at the bottom of the ponds, and in order to maintain the ecological environment of the ponds, it is necessary to remove the silt.

[0003] The following defects exist in the process of dredging ponds:

[0004] Firstly, the existing sludge suction and dredging devices are not convenient for adjusting the size of the suction port. On the one hand, in the edge area of ​​the pond, where the terrain is shallower and there is less sludge accumulation, if the suction port used is too large, it may damage the soil at the bottom of the water and affect the ecological environment. On the other hand, if the suction port is too small when used in areas with thicker sludge, it will not only reduce the efficiency of dredging work, but also make the suction port easy to be blocked by sludge.

[0005] Secondly, most current sludge suction and dredging devices have a suction port with the same inlet and outlet size, resulting in consistent impact intensity between the sludge entering and exiting the liquid. This not only causes the impact force to act directly on the suction port, making it difficult to buffer the impact and limiting the service life, but also causes sludge to clog the conveying pipeline, affecting the conveying efficiency. In view of this, we propose a sludge suction and dredging device for landscaping and its usage method. Summary of the Invention

[0006] The purpose of this invention is to provide a sludge suction and dredging device for landscaping and its usage method, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, one of the objectives of this invention is to provide a sludge suction and dredging device for landscaping, including a suction machine and a chassis connected to the liquid inlet end of the suction machine, wherein the chassis is provided with a suction port assembly for adjusting the size of the liquid inlet.

[0008] The suction port assembly includes at least two symmetrical elastic rods fixedly connected to the inner wall of the chassis, and each of the two elastic rods is rotatably connected to a disturbance plate at one end opposite to the other, and the two symmetrical disturbance plates are rotatably disposed inside the chassis.

[0009] The compression and rebound force generated inside the elastic rod resists the "eight" shape formed by the rotation of the two symmetrical disturbance plates, which accelerates the flow rate of the sludge when passing through the inlet and buffers the impact force generated by the sludge entering from the inlet opened on the side wall of the chassis.

[0010] An auxiliary disturbance component is connected to the rotating shaft of the disturbance plate. It slides inside the chassis via an elastic rod and pushes the disturbance plate to rotate inside the chassis, thereby adjusting the size of the liquid inlet of the chassis.

[0011] Preferably, the suction port assembly further includes two baffles, with one end of the two baffles symmetrically fixed to the inner wall of the chassis, and the other end of the two baffles rotatably connected to the side wall of the disturbance plate away from the chassis, so as to adjust the size of the liquid inlet of the chassis by rotating the disturbance plate on the side wall of the baffle.

[0012] Preferably, the elastic rod specifically includes a slide rod rotatably connected to the inner wall of the disturbance plate, and a first slide rail is slidably connected to the outer wall of the slide rod for sliding the slide rod;

[0013] The side of the slide bar away from the disturbance plate is fixedly connected to the inner wall of the first slide rail with a spring, so as to generate a compressive rebound force inside the elastic rod.

[0014] Preferably, a drive motor is installed inside the chassis, and an output rod is fixedly connected to the output shaft of the drive motor;

[0015] A transmission box is fixedly connected to the lower side of the chassis. A rotating rod is rotatably connected to the inner wall of the transmission box. A belt is sleeved on the outer wall of the rotating rod and the outer wall of the output rod. A first threaded rod is fixedly connected to both ends of the rotating rod.

[0016] A second slide rail is fixedly connected to the lower side of the chassis. A slider is slidably connected to the inner wall of the second slide rail. A first slide rail is rotatably connected to the side wall of the slider so that the elastic rod can slide inside the chassis.

[0017] Preferably, a turbulence rod is rotatably connected to the inside of the side of the turbulence plate away from the baffle, and the outer wall of the turbulence rod is uniformly surrounded by insert rods for disturbing the silt.

[0018] A plug plate is fixedly connected to the lower side of the chassis. Both sides of the plug plate are designed as linear planes, which together form a triangular structure for clearing silt.

[0019] Preferably, the auxiliary disturbance component includes a third slide rail, which is fixedly connected to the upper side of the chassis, and a sliding door is slidably connected to the inner wall of the third slide rail;

[0020] The sliding door is used to slide up and down along the inner wall of the third slide rail to control the opening and closing of the liquid inlet.

[0021] Preferably, a threaded plate is fixedly connected to the side wall of the sliding door. One end of the threaded plate passes through the side wall of the third slide rail and is threadedly connected to a second threaded rod. The lower end of the second threaded rod is fixedly connected to the upper end of the rotating shaft between the disturbance plate and the baffle for rotation of the second threaded rod.

[0022] Preferably, the suction machine is equipped with a conveying component, which includes a pipe. The outer wall of the pipe is fixedly connected to the inner wall of the suction machine. A blade is fixedly connected to the lower inner wall of the pipe, and a grid is fixedly connected to the upper inner wall. A threaded interface is fixedly connected to the upper outer wall of the pipe.

[0023] Preferably, water storage tanks are fixedly connected to both sides of the suction machine, and valves are opened on the upper side of both water storage tanks.

[0024] The second objective of this invention is to provide a method for using a sludge suction and dredging device for landscaping, comprising the sludge suction and dredging device for landscaping described in any one of the above-mentioned embodiments, including the following method steps:

[0025] Step 1: The staff put the sludge suction and dredging device used for landscaping into the pond;

[0026] Step two: The operator starts the suction machine. At this time, the elastic rod slides forward inside the chassis, causing the disturbance plate to rotate and making the suction port area smaller.

[0027] Step 3: When working in the deep water area in the center of the pond, the elastic rod slides backward inside the chassis, causing the disturbance plate to rotate and increasing the suction port area.

[0028] Step four: When a blockage occurs, the sludge compresses the disturbance plate, causing the disturbance plate to rotate, which in turn causes the auxiliary disturbance component to slide down and close the sludge entry channel, cutting off the sludge flow into the channel.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. In this landscaping sludge suction and dredging device and its operating method, the compression and rebound force generated inside the elastic rod resists the "V" shape formed by the rotation of two symmetrical disturbance plates, accelerating the flow velocity of the sludge as it passes through the inlet. Furthermore, considering that direct impact of sludge into the suction machine could damage its internal components, the "V" shape formed by the rotation of the two symmetrical disturbance plates also buffers the impact force generated by the sludge entering through the inlet on the side wall of the chassis. This reduces the risk of blockage, improves work efficiency, and extends the machine's service life by buffering and reducing impact force.

[0031] 2. In this sludge suction and dredging device for landscaping and its usage method, the sludge squeezes the suction port assembly, causing the inner rear end of the suction port assembly to contract and vibrate, thus generating vibration in the sludge. Simultaneously, this drives the auxiliary disturbance component to slide down and close the sludge inlet channel, cutting off the sludge flow into the channel. This continues until the pressure on the suction port assembly decreases, causing the auxiliary disturbance component to reset. At this point, it slides up and opens the sludge inlet channel, allowing the sludge to smoothly enter the suction port assembly. This vibration operation alleviates blockages and prevents blockages from occurring, ensuring smoother dredging operations without frequent interruptions and restarts, thus significantly saving valuable operating time.

[0032] 3. In this sludge suction and dredging device for landscaping and its usage method, the suction port assembly is rotated to change the size of the suction port in order to reduce the suction range. By adjusting the size of the suction port, aquatic organisms can be effectively protected and the ecological balance of the water body can be maintained. In addition, the appropriate size of the suction port can reduce the time required for dredging and save manpower and mechanical resources. Attached Figure Description

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0051] In today's society, with economic development and the continuous improvement of living standards, people's pursuit of quality of life is also increasing. They not only care about their own living conditions but also pay more attention to the quality of their living environment. Therefore, modern communities are increasingly emphasizing the layout of green vegetation in their planning, with carefully designed green belts between buildings to enhance the comfort and aesthetics of the living environment. Some communities even specifically delineate garden areas for residents to relax, enjoy nature, and experience its beauty. These gardens often include thoughtfully designed ponds, adding a touch of tranquility to the community. However, over time, a layer of silt often accumulates at the bottom of these ponds, affecting not only their cleanliness but also potentially harming the aquatic ecosystem. To maintain the ecological environment of the ponds and preserve their clarity and vitality, regular sludge removal from the bottom is crucial. This is not only an aesthetic requirement but also a necessity for ecological balance and residents' health. Therefore, sludge removal from ponds has become an essential part of modern community environmental management. Through such maintenance, ponds can continue to play their proper role, adding more vitality and life to the community environment.

[0052] Please see Figures 1-10 As shown, one of the objectives of this invention is to provide a sludge suction and dredging device for landscaping, including a suction machine 101 and a chassis 105 connected to the liquid inlet end of the suction machine 101. The chassis 105 is provided with a suction port assembly 200 for adjusting the size of the liquid inlet.

[0053] The suction port assembly 200 includes at least two symmetrical elastic rods 203 fixedly connected to the inner wall of the chassis 105, and each of the two elastic rods 203 is rotatably connected to a disturbance plate 207 at one end opposite to the other. The two symmetrical disturbance plates 207 are rotatably disposed inside the chassis 105.

[0054] The compression and rebound force generated inside the elastic rod 203 resists the "eight" shape formed by the rotation of the two symmetrical disturbance plates 207, accelerating the flow rate of the sludge when passing through the inlet, and buffering the impact force generated by the sludge entering from the inlet opened on the side wall of the chassis 105.

[0055] An auxiliary disturbance component 210 is connected to the pivot of the disturbance plate 207. It slides inside the chassis 105 via an elastic rod 203, which pushes the disturbance plate 207 to rotate inside the chassis 105 to adjust the size of the liquid inlet of the chassis 105.

[0056] This invention takes into account the specific conditions of different areas when dredging ponds. For example, in the shallower areas around the pond's edges, there is less silt buildup. In this case, using a suction nozzle that is too large may damage the bottom soil, negatively impacting the ecosystem. This damage could harm the growth environment of aquatic plants, affecting their normal growth. On the other hand, the deeper water areas in the center of the pond typically have thicker layers of silt. If the suction nozzle used in these areas is the same size as in the pond's edges, the nozzle size may be relatively small. This would reduce the efficiency of the dredging work, as a smaller nozzle might not be able to effectively remove the thick silt. Furthermore, the machine requires a longer time to complete the dredging work, which not only prolongs the working time but may also adversely affect the machine's lifespan. Therefore, when dredging at the edge of the park, the suction nozzle assembly 200 is rotated to change the size of the suction nozzle, thereby narrowing the extraction range. At the same time, the rear end of the suction nozzle assembly 200 rotates to ensure smooth flow of the sludge until it enters the conveying assembly 300, where it is extracted from the pond. By adjusting the size of the suction nozzle, aquatic life can be effectively protected, and the ecological balance of the aquatic body can be maintained. When moving to the deep water area in the center of the park for dredging, the suction nozzle assembly 200 is rotated again to expand the extraction range. At this time, the rear end of the suction nozzle assembly 200 rotates to disturb the sludge. The appropriate suction nozzle size can reduce the time required for dredging and save manpower and mechanical resources.

[0057] Secondly, this invention considers that a straight inlet design might result in a slower flow rate at the suction port, thus reducing suction efficiency. A slower flow rate means slower movement of sludge and water, requiring more time to complete the suction operation. Furthermore, the reduced flow rate could lead to insufficient negative pressure at the suction port, reducing suction power. Insufficient suction power increases the risk of blockage, affecting the normal operation of the suction machine 101. Therefore, the invention utilizes the compressive rebound force generated inside the elastic rod 203 to counteract the "V" shape formed by the rotation of the two symmetrical disturbance plates 207, accelerating the flow rate of sludge as it passes through the inlet. Considering that direct impact of sludge into the suction machine 101 could damage its internal structure, the "V" shape formed by the rotation of the two symmetrical disturbance plates 207 also buffers the impact force generated by sludge entering through the inlet on the side wall of the chassis 105. This reduces the risk of blockage, improves working efficiency, and extends the machine's lifespan by buffering and reducing impact force.

[0058] Furthermore, this invention fully considers potential problems that may arise when extracting large amounts of sludge. Specifically, if the amount of sludge is too large, it may cause blockage inside the machine, leading to interruption of the work process. More seriously, such blockage may also damage the machine. Therefore, when the inlet of the suction assembly 200 is blocked, the sludge squeezes the suction assembly 200, causing a disturbance on the inner rear end of the suction assembly 200. This causes the sludge to vibrate and simultaneously drives the auxiliary disturbance component 210 to slide down and close the sludge inlet channel, cutting off the sludge flow. This continues until the pressure on the suction assembly 200 decreases, causing the auxiliary disturbance component 210 to reset. At this point, it slides up and opens the sludge inlet channel, allowing the sludge to smoothly enter the suction assembly 200. This vibration operation alleviates the blockage and prevents blockage from occurring, ensuring smoother dredging operations without frequent interruptions and restarts of the equipment, thus significantly saving valuable working time.

[0059] The present invention needs to disclose the following in the above:

[0060] Firstly, adjusting the size of the suction inlet can effectively protect aquatic life and maintain the ecological balance of the water body. Furthermore, adjusting the suction inlet size appropriately during operation can reduce the time required for dredging and save manpower and mechanical resources. Figures 2-4 As shown, the suction port assembly 200 also includes two baffles 202 symmetrically fixedly connected to the inner wall of the chassis 105. Each of the two baffles 202 is rotatably connected to one side of a disturbance plate 207 on opposite sides, so that the size of the liquid inlet of the chassis 105 can be adjusted by rotating the disturbance plate 207 on the side wall of the baffles 202. A drive motor 201 is installed inside the chassis 105, and an output rod 2011 is fixedly connected to the output shaft of the drive motor 201. A transmission box 2014 is fixedly connected to the lower side of the chassis 105. A rotating rod 2013 is rotatably connected to the inner wall of the chassis 105. A belt 2012 is sleeved on the outer wall of the rotating rod 2013 and the outer wall of the output rod 2011. First threaded rods 2015 are fixedly connected to both ends of the rotating rod 2013. A second slide rail 2017 is fixedly connected to the lower side of the chassis 105. A slider 2016 is slidably connected to the inner wall of the second slide rail 2017. A first slide rail 2032 is rotatably connected to the side wall of the slider 2016, allowing the elastic rod 203 to slide inside the chassis 105. Wherein:

[0061] The baffle 202 is used to fix the disturbance plate 207 inside the chassis 105 and provide a platform for the disturbance plate 207 to rotate, making the rotation of the disturbance plate 207 more stable. The disturbance plate 207 is used to contact the sludge, and by rotating inside the chassis 105, the size of the liquid inlet of the chassis 105 can be adjusted to suit different working environments. The drive motor 201 rotates through its output end to drive the output rod 2011 to rotate. The output rod 2011 rotates to drive the belt 2012 to rotate, thereby driving the rotating rod 2012 through the rotation of the belt 2012. Rotating rod 2013 drives the first threaded rod 2015 to rotate, which in turn generates a helical drive that moves slider 2016 back and forth within the second slide rail 2017. This movement of slider 2016 within the second slide rail 2017 drives the first slide rail 2032 to move within the chassis 105. The first slide rail 2032, in turn, moves slide rod 2031, which in turn pushes the disturbance plate 207 to rotate within the chassis 105, thereby adjusting the size of the liquid inlet of the chassis 105. By adjusting the size of the suction inlet, aquatic life can be effectively protected, the ecological balance of the water body maintained, and the time required for dredging can be reduced during operation, saving manpower and mechanical resources.

[0062] Secondly, the compression and rebound force generated inside the elastic rod 203 should be used to resist the "eight" shape formed by the rotation of the two symmetrical disturbance plates 207, thereby increasing the flow velocity of the sludge as it passes through the inlet and buffering the impact force generated by the sludge entering from the inlet on the side wall of the chassis 105. Figures 7-8 As shown, the elastic rod 203 specifically includes a slide rod 2031 rotatably connected to the inner wall of the disturbance plate 207. A first slide rail 2032 is slidably connected to the outer wall of the slide rod 2031 for sliding the slide rod 2031. A spring 2033 is fixedly connected to the side of the slide rod 2031 away from the disturbance plate 207 and the inner wall of the first slide rail 2032 for generating a compressive rebound force inside the elastic rod 203.

[0063] The slide rod 2031 is used to push the disturbance plate 207 to rotate. The first slide rail 2032 is used to allow the slide rod 2031 to slide into the first slide rail 2032 when it is squeezed by the disturbance plate 207, thereby shrinking and driving the disturbance plate 207 to rotate. At this time, the spring 2033 shrinks when it is subjected to the pressure transmitted by the slide rod 2031, and then generates a rebound force to push the slide rod 2031 out of the first slide rail 2032, thereby pushing the disturbance plate 207 in the opposite direction again. Thus, the elastic rod 203 achieves compression and rebound force generated inside, which resists the "eight" shape formed by the rotation of the two symmetrical disturbance plates 207, thereby accelerating the flow rate of the sludge when it passes through the liquid inlet and buffering the impact force generated by the sludge entering from the liquid inlet opened on the side wall of the chassis 105. This effectively protects the mechanical structural parts inside the suction machine 101 and extends its service life.

[0064] Secondly, to achieve a better effect of clearing silt with the disturbance plate 207, therefore, as Figures 2-3 As shown, a turbulence rod 206 is rotatably connected inside the side of the turbulence plate 207 away from the baffle 202. Insert rods 204 are evenly surrounding the outer wall of the turbulence rod 206 to agitate the silt. An insert plate 205 is fixedly connected to the lower side of the chassis 105. Both sides of the insert plate 205 are designed as linear planes, forming a triangular structure for clearing silt.

[0065] The baffle bar 206 is used to continuously impact the surface of the sludge as it enters. Under the impact force, the baffle bar 206 rotates continuously, and during rotation, it drives the insert bar 204 on the surface to rotate as well. This allows the sludge to be continuously penetrated as it enters, thus effectively clearing the sludge. The insert plate 205, through its triangular structure design, can divert the sludge impacted directly, splitting it into two streams when it flows into the suction machine 101, effectively preventing the suction machine 101 from becoming clogged and improving its working efficiency.

[0066] The next step is to alleviate blockages through vibration, preventing blockages from occurring and ensuring smoother dredging operations without frequent interruptions and restarts, thus significantly saving valuable operation time. Figures 2 to 6As shown, the auxiliary disturbance component 210 includes a third slide rail 211, which is fixedly connected to the upper side of the chassis 105. A sliding door 212 is slidably connected to the inner wall of the third slide rail 211. The sliding door 212 is used to slide up and down along the inner wall of the third slide rail 211 to control the opening and closing of the liquid inlet. A threaded plate 214 is fixedly connected to the side wall of the sliding door 212. One end of the threaded plate 214 passes through the side wall of the third slide rail 211 and is threadedly connected to a second threaded rod 213. The lower end of the second threaded rod 213 is fixedly connected to the disturbance plate 207 and the baffle. The upper end of the shaft between 202 is used for the rotation of the second threaded rod 213. The suction machine 101 is internally equipped with a conveying assembly 300, which includes a pipe 301. The outer wall of the pipe 301 is fixedly connected to the inner wall of the suction machine 101. A blade 303 is fixedly connected to the lower inner wall of the pipe 301, and a grid mesh 302 is fixedly connected to the upper inner wall. A threaded interface 102 is fixedly connected to the upper outer wall of the pipe 301. Water storage tanks 103 are fixedly connected to both sides of the suction machine 101. Valves 104 are opened on the upper side of both water storage tanks 103.

[0067] The third slide rail 211 is used to limit the sliding trajectory of the sliding door 212 and improve the stability of the sliding. The sliding door 212 is used to control the opening and closing of the liquid inlet by sliding up and down. The second threaded rod 213 is rotated by the rotation of the disturbance plate 207, thereby generating a helical drive to drive the threaded plate 214 to move up and down. The threaded plate 214, by moving up and down, drives the sliding door 212 to slide up and down. The pipe 301 is used to transport the sludge entering the suction machine 101 to the ground. The blade 303 is used to further divide the sludge to prevent the pipe 301 from clogging. The grid 302 is used to break up and finer the larger clumps of sludge, making the sludge transport to the ground smoother. The water tank 103 is filled with water by opening and closing the valve 104, which causes the suction machine 101 to sink and float. This improves the time to resume work in case of blockage, effectively reduces the working time delayed by blockage, and improves work efficiency.

[0068] The second objective of this invention is to provide a method for using a sludge suction and dredging device for landscaping, comprising the following steps:

[0069] Step 1: The staff put the sludge suction and dredging device used for landscaping into the pond;

[0070] Step 2: The operator starts the suction machine 101. At this time, the elastic rod 203 slides forward inside the chassis 105, causing the disturbance plate 207 to rotate, thus reducing the suction port area.

[0071] Step 3: When working in the deep water area in the center of the pond, the elastic rod 203 slides backward inside the chassis 105, causing the disturbance plate 207 to rotate, thereby increasing the suction port range.

[0072] Step four: When a blockage occurs, the sludge compresses the disturbance plate 207, causing the disturbance plate 207 to rotate, thereby causing the auxiliary disturbance component 210 to slide down and close the sludge entry channel, cutting off the sludge flow into the channel.

[0073] The specific working principle of this invention is as follows:

[0074] During equipment operation, the suction machine 101 is first started. With the activation of the suction machine 101, the water storage tank 103 immediately opens valve 104, allowing water to flow smoothly and ensuring the machine sinks smoothly to the bottom. When the equipment operates in the edge area of ​​the pond, the output shaft of the drive motor 201 transmits power to the rotating rod 2013 via the drive output rod 2011 through the belt 2012, thereby driving the first threaded rod 2015 to rotate. This rotation causes the slider 2016 to move forward along a preset trajectory, triggering the rotation of the disturbance plate 207 and reducing the working range of the suction port.

[0075] When the equipment is moved to the deep water area in the center of the pond, the output shaft of the drive motor 201 transmits power to the rotating rod 2013 via the belt 2012 through the rotation of the drive output rod 2011, thereby driving the first threaded rod 2015 to rotate. At this time, the rotation of the first threaded rod 2015 causes the slider 2016 to move backward, driving the disturbance plate 207 to rotate, thereby expanding the working range of the suction port.

[0076] When a blockage occurs, the accumulation of sludge activates the rotation of the disturbance plate 207. This rotation drives the second threaded rod 213 to rotate synchronously, which in turn drives the threaded plate 214 to move vertically via a screw transmission mechanism. Subsequently, the movement of the threaded plate 214 causes the sliding door 212 to move up and down, closing the inlet and effectively alleviating the blockage. This design not only effectively prevents the blockage from worsening but also ensures the continuity and efficiency of the dredging operation, eliminating the need for frequent interruptions or restarts of the equipment, significantly improving operational efficiency and saving valuable operating time.

[0077] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

8. A method of using the sludge suction and dredging device for landscaping as described in claim 5, characterized in that, The methods and steps include the following: Step 1: The staff put the sludge suction and dredging device used for landscaping into the pond; Step 2: The operator starts the suction machine (101). At this time, the elastic rod (203) slides forward inside the chassis (105), causing the disturbance plate (207) to rotate, thus reducing the suction port area. Step 3: When working in the deep water area in the center of the pond, the elastic rod (203) slides backward inside the chassis (105), causing the disturbance plate (207) to rotate, thereby increasing the suction port range; Step 4: When a blockage occurs, the sludge squeezes the disturbance plate (207), causing the disturbance plate (207) to rotate, thereby causing the auxiliary disturbance component (210) to slide down and close the sludge entry channel, cutting off the sludge flow into the channel.
