Description

Technical Field

[0001] This application relates to the field of soil remediation, and more particularly to a vegetation irrigation device for soil remediation. Background Technology

[0002] Vegetation remediation is a commonly used and effective soil remediation method. Plants absorb, fix, and transform pollutants in the soil through their root systems, while simultaneously improving soil structure, increasing soil fertility, and promoting the activity of soil microorganisms, thereby accelerating the natural soil remediation process. A stable and suitable water supply is crucial in vegetation remediation, directly affecting the healthy growth of vegetation and the effectiveness of remediation. Therefore, efficient irrigation systems are one of the key elements to ensure the smooth progress of vegetation remediation.

[0003] However, traditional irrigation devices cannot guarantee that vegetation in the entire restoration area can receive water evenly. This often results in some vegetation growing poorly due to lack of water, or localized excessive water leading to soil nutrient loss and root rot, which in turn negatively impacts the soil restoration results.

[0015] This application provides a vegetation irrigation device for soil remediation. An arc-shaped connecting plate is welded to one end of the connecting handle. This plate can be fixedly mounted on an agricultural construction trolley, providing a convenient platform for the entire device's movement. A drive motor is installed on the lower surface of the supporting chassis. When the drive motor starts, its output end generates strong power, driving the connected transmission screw to rotate at high speed. The transmission screw has a standard thread on its surface. The movable sleeve connected to this thread moves upward or downward according to the rotation direction of the drive motor when the screw rotates. For example, when the drive motor rotates clockwise, the movable sleeve moves along... The threaded trajectory of the transmission screw rises slowly; conversely, if the drive motor rotates counterclockwise, the moving sleeve will gradually descend. The stable movement of the moving sleeve provides precise height adjustment for various actuators connected to it, such as irrigation nozzles and soil conditioner sprayers. The vegetation is covered inside the hood by the cover and the spray assembly. The spray assembly sprays water in a fine and uniform mist, ensuring that the water is distributed in all directions without dead angles inside the hood. This not only provides sufficient water for the vegetation to meet the water requirements of different vegetation at various growth stages, but also ensures that every leaf, whether at the top or bottom of the plant, inside or outside, is evenly irrigated.

[0027] Vegetation remediation is a commonly used and effective soil remediation method. Plants absorb, fix, and transform pollutants in the soil through their root systems, while simultaneously improving soil structure, increasing soil fertility, and promoting the activity of soil microorganisms, thereby accelerating the natural soil remediation process. A stable and suitable water supply is crucial in vegetation remediation, directly affecting the healthy growth of vegetation and the effectiveness of remediation. Therefore, efficient irrigation systems are one of the key elements to ensure the smooth progress of vegetation remediation.

[0028] An investigation revealed that a Chinese utility model patent (publication number: CN211330724U) discloses a vegetation irrigation device for soil remediation, comprising a shell and a base plate. The shell is fixed to the upper end of the base plate, and a water tank is fixed to the center of the shell's interior. Cylinders are installed at the four corners of the bottom of the shell's interior. A water pump is fixed to the upper end of the water tank. A diversion pipe is fixed to the center of the lower end of the base plate, and a nozzle is fixed to the lower end of the diversion pipe. Mounting blocks are fixed to the left and right sides of the lower end of the base plate, and rollers are installed at the front and rear of each mounting block. Mounting rods are fixed to the ends of the rollers corresponding to the mounting blocks. Limiting rods are installed at the upper end of the base plate corresponding to the mounting rods. This device, by incorporating mounting rods, limiting rods, a water pump, rollers, diversion pipes, and nozzles, solves the problems of traditional vegetation irrigation devices for soil remediation lacking the ability to adjust for the distance between rows and the ability to provide rapid and comprehensive irrigation, offering a new approach to achieving efficient irrigation.

[0029] However, this irrigation device cannot guarantee that the vegetation in the entire restoration area can obtain water evenly. It often results in some vegetation growing poorly due to lack of water, or local excessive water leading to soil nutrient loss and plant root rot, which in turn negatively affects the soil restoration results.

[0030] To address the aforementioned issues, this application proposes a vegetation irrigation device for soil remediation, aiming to solve the technical problem that traditional irrigation devices cannot guarantee that vegetation throughout the remediation area can receive water evenly.

[0031] The following is a detailed description of the proposed solution with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the overall irrigation structure in an embodiment of this application. Figure 2 This is a top view of the cover structure in an embodiment of this application. Figure 3 This is a partial cross-sectional view of the spray assembly in an embodiment of this application. Figure 4 This is a schematic diagram of the disassembled internal structure of the spray assembly in an embodiment of this application. Figure 5 This is a top view of the cover structure in an embodiment of this application.

[0033] This application provides a vegetation irrigation device for soil remediation, such as... Figures 1 to 5As shown, the device may include: a connecting handle 1, a drive motor 2, a transmission screw 3, a movable sleeve 4, a straight-through water pipe 5, a spray assembly 6, and a shroud 7; wherein, the connecting handle 1 has two end faces, one side is provided with an arc-shaped connecting plate 101, and the side of the connecting handle 1 away from the arc-shaped connecting plate 101 is provided with a receiving base 102; the side of the drive motor 2 away from the output end is connected to the receiving base 102; one end of the transmission screw 3 is fixedly installed at the output end of the drive motor 2; the movable sleeve 4 is movably sleeved on the transmission screw 101. The surface of rod 3 is threadedly connected to the transmission screw 3. Multiple corresponding through holes are arranged in a circumferential array on the top plate and bottom plate opposite to the movable sleeve column 4, and the top plate and bottom plate are connected by a connecting rod. Multiple straight water pipes 5 are provided, with one end of each straight water pipe passing through the corresponding through hole and extending to the surface of the top plate. The spray assembly 6 is located on the side of the transmission screw 3 away from the drive motor 2, and the spray assembly 6 is movably connected to the other end of the straight water pipe 5. The cover 7 is threadedly connected to the side of the spray assembly 6 away from the transmission screw 3.

[0034] Specifically, the connecting handle 1 has an arc-shaped structure, with an arc-shaped connecting plate 101 welded to one end. Threaded holes are machined into the surface of the arc-shaped connecting plate 101, allowing it to be securely fixed to the agricultural construction trolley via these holes, providing a convenient platform for the entire device's movement. A drive motor 2 is installed on the lower surface of the supporting chassis 102. When the drive motor 2 starts, its output end generates strong power, driving the connected transmission screw 3 to rotate at high speed. The transmission screw 3 has standard threads on its surface, and the movable sleeve 4, threadedly connected to it, moves upwards or downwards according to the rotation direction of the drive motor 2 as the screw rotates. Moving downwards, for example, when the drive motor 2 rotates clockwise, the moving sleeve 4 will slowly rise along the threaded trajectory of the transmission screw 3; conversely, if the drive motor 2 rotates counterclockwise, the moving sleeve 4 will gradually descend. The stable movement of the moving sleeve 4 provides precise height adjustment for various actuators connected to it, such as irrigation nozzles and soil conditioner spraying. In this way, during soil remediation operations, the positions of relevant components can be flexibly and accurately adjusted according to the actual soil conditions and vegetation growth needs of different areas, ensuring that irrigation and soil remediation agent application can be carried out efficiently and accurately, greatly improving the efficiency and quality of soil remediation work.

[0035] The spray assembly 6 may include a multi-port pipe head 601, a connecting sleeve 602, a branch port 603, and a pipe body 606. One end of the multi-port pipe head 601 is connected to a straight-through water pipe 5. The multi-port pipe head 601 has an external thread on one side of its outer arc surface. The connecting sleeve 602 is connected to the external thread of the multi-port pipe head 601. The branch port 603 is located in the middle of the lower surface of the multi-port pipe head 601 on one side. One end of the pipe body 606 is connected to the branch port 603. The bottom of the outer arc surface of the branch port 603 has an external thread. The inner arc surface of the multi-port pipe head 601 is hollow. The inner arc surface of the branch port 603 is connected to the multi-port pipe head 601. A locking clamp 604 is fixedly installed on the inner arc surface of the connecting sleeve 602. The locking clamp 604 has an elastic end 605 on one side of its outer arc surface. The conical structure has one side of the elastic end 605 tapering inward. The inner arc surface of the locking clamp 604 is connected to the outer arc surface of the straight water pipe 5. The bottom of the outer arc surface of the straight water pipe 5 is provided with a water outlet 501 near the multi-port pipe head 601. The water outlet 501 is vertically adapted to the cover 7. The pipe body 606 is provided with a ball head 607 at one end of the inner arc surface of the branch port 603. A ball valve 608 is sleeved at the bottom of the inner arc surface of the pipe body 606. A spray hole 609 is provided at the bottom of the outer arc surface of the ball valve 608. A sealing gasket is provided in the middle of the outer arc surface of the ball valve 608. A spray sleeve 610 is threadedly connected to the side of the pipe body 606 near the ball valve 608. One end of the spray sleeve 610 is sleeved in the inner arc surface of the cover 7. A threaded drill bit 8 is sleeved on the outer arc surface of the pipe body 606.

[0036] The straight-through water pipe 5 and the multi-way pipe head 601 are connected by a locking clamp 604. The front end of the locking clamp 604 is designed as an elastic end 605. When no external force is applied, its inner diameter is slightly smaller than the outer diameter of the straight-through water pipe 5, forming an initial state of interference fit. During installation, the operator inserts the straight-through water pipe 5 into the inlet of the multi-way pipe head 601. During insertion, the elastic end 605 is in close contact with the outer wall of the water pipe. As the insertion depth increases, the elastic end 605 undergoes elastic deformation due to compression, and its internal potential energy continuously accumulates, forcing the elastic end 605 to... The diameter of the middle section of 05 gradually expands. This adaptive expansion mechanism not only ensures that the water pipe can pass smoothly through the locking clamp 604 and enter the multi-port head 601, but also, after insertion, the straight water pipe 5 is firmly locked in the multi-port head 601 by the tightening force generated by the rebound of the elastic end 605. The stable movement of the movable sleeve 4 provides a precise height adjustment function for various actuators connected to it, such as irrigation nozzles and soil conditioner spraying devices. When installing the movable sleeve 4, the bottom surface of the cover 7 should be placed stably on the surface of the vegetation soil. As the movable sleeve 4 continues to move downwards, the plate on the bottommost movable sleeve 4 will abut against the surface of the multi-port head 601. During the continuous downward pressing of the movable sleeve 4, the threaded drill bit 8 inside the bottom bending surface 703 will slowly extend from the inner arc surface of the cover 7, and then, with its sharp thread structure, quickly and firmly insert into the soil. After being inserted into the soil, the threaded drill bit 8 will continue to rotate, drilling holes of appropriate depth and even distribution in the soil. These holes can greatly enhance the soil permeability, promote the activity of microorganisms in the soil, and accelerate the soil remediation process. On the other hand, they provide a convenient channel for the subsequent precise injection of irrigation water, fertilizer, and soil conditioner into the soil through the multi-port head 601, ensuring that these remediation materials can directly reach the key areas around the plant roots, fully exert their effects, significantly improve the effectiveness and efficiency of soil remediation, help vegetation grow vigorously in contaminated soil, and achieve rapid restoration and reconstruction of the soil ecosystem.

[0037] The cover 7 may include a connecting section 701, a hook-shaped end 702, and a bending surface 703. The connecting section 701 has an internal thread at the top of its inner arc surface and is threaded to the outer arc surface of the branch port 603. The hook-shaped end 702 is located at the bottom of the outer arc surface of the cover 7. The bending surface 703 is located in the middle section of the inner arc surface of the cover 7. The inner arc surface of the bending surface 703 is located at the bottom of the pipe body 606. A through hole is provided in the upper surface of the bending surface 703. The hook-shaped end 702 at the bottom of the outer arc surface of the cover 7 is in the same plane as the multi-port pipe head 601 at the top. The vertical distribution of the cover 7 at the bottom of the multi-port pipe head 601 ensures that the water flow can be concentrated inside the cover 7.

[0038] Meanwhile, straight-through water pipes 5 are evenly connected to the periphery of the multi-port head 601. These water pipes are laid according to a planned path and eventually converge inside the multi-port head 601. After being integrated by the multi-port head 601, the water flows out uniformly from the branch port 603 at the bottom. It is worth mentioning that on the back of the branch port 603, a pipe body 606 connected by a ball head 607 is installed through a flexible movable connection. When the water reaches the branch port 603, it enters the pipe body 606 through the ball head 607 and is evenly sprayed out from the spray holes 609 distributed on the bottom ball valve 608. The threaded drill bit 8 previously inserted into the soil not only... It creates channels for air circulation and material transport, playing a crucial role in irrigation. Because the holes drilled in the soil correspond to the spray positions of the ball valve 608, the sprayed water can quickly penetrate into the deeper soil layers along these holes, reducing water loss and evaporation at the soil surface and improving the utilization rate of irrigation water. Furthermore, after dissolving in the irrigation water, fertilizers and soil conditioners can also be precisely delivered to the plant roots through this channel, greatly improving the utilization efficiency of nutrients and soil conditioners. This provides more stable and efficient support for soil remediation and vegetation growth, further ensuring the smooth progress of soil ecosystem restoration work.

[0039] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
