Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology for hilly areas, and in particular to a vegetation restoration method and apparatus based on phytoremediation. Background Technology

[0002] Hill erosion mainly occurs on hilly slopes in the tropical and subtropical humid monsoon climate zones of South and Southeast China. It is an erosion phenomenon in which soil and rock masses collapse and vegetation is destroyed under the action of water and gravity. In recent years, early restoration of hill erosion areas has mostly adopted nature-based solutions for ecological restoration, such as creating large-scale artificial forests with different tree species and rationally configuring understory plants according to the characteristics of tree species, so as to achieve better near-natural restoration results more quickly.

[0003] Commonly used tree species for restoration in landslide-prone areas include eucalyptus, fir, pine, tea tree, and bamboo. Different species, due to their varying characteristics, will form different understory plant communities during the forest maturation process. Understory plants are an important component of the forest ecosystem, typically including native and introduced plants. Introduced plants may compete fiercely with native plants, becoming invasive species, occupying more ecological niches, reducing community species diversity, and negatively impacting interspecific relationships. Species diversity reflects the adaptability of different species and species combinations to different environments. Ecological niche is the position, function, and status of a species within a community, reflecting its ability to utilize resources and serving as an important basis for selecting pioneer plants. Interspecific relationships are the spatial competition, coexistence, or random relationships between species, reflecting the stability between species and applicable to plant community configuration. Plant diversity, ecological niche, and interspecific relationships are hot topics in modern ecology.

[0004] Many scholars have conducted multi-faceted research on understory plants to explore the effects of ecological restoration, but there is relatively little research on understory plants in landslide-prone areas.

[0005] Eucalyptus urophylla STBlake is a plant belonging to the genus Eucalyptus in the family Myrtaceae. Eucalyptus trees do not have a negative impact on understory plant diversity. Studies have shown that the understory plant diversity of eucalyptus forests is not significantly lower than that of other plantations. The greater the diversity of native plants, the smaller the ecological niche that invasive plants can occupy in the community, resulting in fewer resources for invasive plants. This is beneficial to reducing plant invasion to some extent. The number of native species under Eucalyptus urophylla forests ranks second, which has a positive effect on reducing the successful invasion of alien plants.

[0006] In the process of vegetation restoration, Eucalyptus urophylla is usually chosen to improve local plant diversity. The transplanting of Eucalyptus urophylla usually needs to be done manually, with low automation and no corresponding equipment to improve the efficiency of eucalyptus seedling planting. Summary of the Invention

[0007] This invention provides a vegetation restoration method based on phytoremediation, which can overcome some or all the defects of the prior art.

[0008] A vegetation restoration method based on phytoremediation according to the present invention includes the following steps:

[0009] In the early stages of hillside restoration, Eucalyptus urophylla was used as a pioneer tree species for planting to facilitate rapid forest formation.

[0010] In the later stages of gully restoration, other tree species, including slash pine, large-leaved acacia, and camphor tree, are added to increase forest diversity and create a more natural restoration model.

[0011] The present invention also provides a vegetation restoration device based on phytoremediation, which includes a feeding mechanism for storing seedlings. A vortexing mechanism is movably arranged on the lower surface of the feeding mechanism. The vortexing mechanism digs pits by rotating. A transplanting mechanism is arranged in the middle of the vortexing mechanism. The feeding mechanism transfers the stored seedlings to the transplanting mechanism. The transplanting mechanism plants the seedlings into the pits by widening the opening.

[0012] The seedlings are placed in the feeding mechanism for storage, and the soil is dug by the equipment's vortexing mechanism. After the digging is completed, the feeding mechanism pushes a group of seedlings into the transplanting mechanism, which then plants the seedlings vertically in the dug pits. No manual transplanting is required during this process, saving time and effort.

[0013] Preferably, the feeding mechanism is fixed with a mounting frame, which is connected to the traction device and used to drive the device to move.

[0014] The traction equipment can be a tractor or similar device, which can move the equipment for planting. The traction equipment also needs to be equipped with a lifting device to lift the drive device, thereby performing the digging and transplanting operation. The lifting device can be a hydraulic cylinder or a robotic arm, etc.

[0015] Preferably, the feeding mechanism includes a first housing, a first drive gear is provided on the edge of the first housing, a gear disk is rotatably connected to the inner surface of the first housing, the gear disk meshes with the first drive gear, a plurality of placement channels are arranged around the surface of the gear disk, seedlings are linearly arranged in the placement channels, a pushing component is fixed to the outer wall of the first housing, the pushing component is used to push the seedlings in the placement channels to the opening and fall into the transplanting mechanism, the pushing component includes a pushing cylinder fixed to the outer wall of the first housing, and a pushing plate is fixedly connected to the telescopic end of the pushing cylinder.

[0016] The pushing cylinder of the pushing component can drive the pushing plate to extend into a single set of placement channels, pushing the arranged saplings one by one into the opening and vertically falling into the transplanting mechanism. As the saplings in a set of placement channels are pushed out, the first drive gear will rotate through the motor, thereby driving the gear disk to rotate at a certain angle, so that the other set of placement channels is aligned with the pushing cylinder, and then the next round of transplanting operation can be carried out.

[0017] Preferably, the swirl mechanism includes a second housing rotatably connected to the lower surface of the first housing, a second drive gear fixed to the edge of the lower surface of the first housing, the second drive gear meshing with the tooth groove of the outer wall of the second housing, a plurality of digging components movably connected to the inner ring of the second housing, and a drive assembly for driving the digging components to gather and disperse inside the second housing.

[0018] By setting a second drive gear to rotate through the motor, the second housing and the digging component are driven to rotate, thereby digging the soil. While digging the pit, the drive component can drive the digging component to spread outward, thereby further expanding the diameter of the pit and pushing the diggered soil outward.

[0019] Preferably, the drive assembly includes a gear ring rotatably connected inside the second housing, the gear ring being driven to rotate by a third drive gear, and several sets of the excavating components being movably connected to the gear ring.

[0020] By setting a third drive gear, it can be rotated by the motor, thereby causing the meshing gear ring to rotate. As it rotates, the spacing of the excavating components that are movably connected to its inner wall changes.

[0021] Preferably, the excavating component includes a connecting strip rotatably connected to the inner wall of the toothed ring, a soil-pushing blade is provided on the lower surface of the connecting strip, a pointed end is provided at the lower end of the soil-pushing blade, and the outer surface of the soil-pushing blade has an arc-shaped structure. In the initial state, the lower ends of the pointed ends are in contact with each other.

[0022] In the initial state, the lower ends of the tips are in contact with each other, ensuring that the converging tips can increase the pressure in the early stages of digging, thus improving the effect of digging in the early stages. The transplanting mechanism located in the center of the soil-pulling blade will not come into contact with the soil and stones first, thus protecting the transplanting mechanism. At the same time, as the digging work progresses, the soil-pulling blade will slowly spread outward through the drive component to improve the effect of subsequent digging and soil removal, and also to loosen the soil.

[0023] Preferably, the transplanting mechanism includes two sets of transplanting tubes movably disposed on the lower surface of the first housing. The upper end of the transplanting tube is funnel-shaped and corresponds to the opening, and the lower end of the transplanting tube is conical. A drive motor is disposed on the lower surface of the first housing, and the drive motor drives the two sets of transplanting tubes to open and close through a bidirectional lead screw at the output end.

[0024] By setting up a vortexing mechanism, the soil can be vortexed. The drive motor of the transplanting mechanism will drive the bidirectional lead screw to rotate, thereby causing the two sets of transplanting tubes to move in opposite directions, so that the seedlings inside fall down into the pit.

[0025] Preferably, a piston rod is fixedly connected to one side of one of the transplanting tubes, the piston rod is connected to the material box, and a spray nozzle connected to the piston rod is opened on the inner wall of the lower end of the transplanting tube.

[0026] By setting a piston rod, the fertilizer solution in the feed box can be drawn into the piston rod by the closing operation of the transplanting tube. As the transplanting tube opens, it pushes the piston rod, spraying the drawn fertilizer solution out from the spray nozzle at the bottom, thereby fertilizing the planting location.

[0027] As can be seen from the above, the vegetation restoration method and apparatus based on phytoremediation provided by the present invention have the following technical effects.

[0028] (1) The invasive plant niche width of the understory of Eucalyptus urophylla forest used in this invention is the smallest; and the niche overlap between the invasive plants and native plants is also the smallest, indicating that the native plants under the forest have a higher resource utilization capacity; at the same time, there are a large number of Miscanthus sinensis under Eucalyptus urophylla forest; its importance value and niche width are the largest; Miscanthus sinensis has an ecological screening effect and strong competitiveness; making it difficult for other species to invade.

[0029] (2) The seedlings are placed in the feeding mechanism for storage, and the soil can be dug through the vortex mechanism of the equipment. After the digging is completed, the feeding mechanism will push a group of seedlings into the transplanting mechanism, and the transplanting mechanism will plant the seedlings vertically in the newly dug pit. During this period, no manual transplanting operation is required, which saves time and effort.

[0030] (3) By setting the second drive gear to rotate through the motor, the second housing and the digging component are driven to rotate, thereby digging the soil. While digging the pit, the drive component can drive the digging component to spread outward, thereby further expanding the diameter of the pit and pushing the soil being dug outward.

[0031] (4) The lower ends of the pointed parts are in contact with each other in the initial state, which ensures that the gathered pointed parts can increase the pressure in the early stage of digging, improve the effect in the early stage of digging, and the transplanting mechanism located in the center of the soil-pulling plate will not come into contact with the soil and stones first, which can protect the transplanting mechanism.

[0032] (5) By setting a piston rod, the fertilizer solution in the feed box can be drawn into the piston rod by the closing operation of the transplanting tube. As the transplanting tube opens, it will push the piston rod and spray the drawn fertilizer solution from the spray nozzle at the bottom, thereby fertilizing the planting position.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] The vegetation restoration device based on phytoremediation disclosed in this invention is mainly applied to the scenario of efficiently planting eucalyptus seedlings in vegetation restoration methods.

[0044] Reference Figure 2 and Figure 3 A vegetation restoration device based on phytoremediation includes a feeding mechanism 1 for storing seedlings. A vortexing mechanism 3 is movably arranged on the lower surface of the feeding mechanism 1. The vortexing mechanism 3 digs pits by rotating. A transplanting mechanism 4 is arranged in the middle of the vortexing mechanism 3. The feeding mechanism 1 transfers the stored seedlings to the transplanting mechanism 4. The transplanting mechanism 4 plants the seedlings into the pits by widening the opening.

[0045] In this embodiment, during the planting and transplanting of Eucalyptus urophylla seedlings, the seedlings can be placed in the feeding mechanism 1 for storage. Then, the vortexing mechanism 3 of the equipment can dig a hole in the soil. After the hole is dug, the feeding mechanism 1 will push a group of seedlings into the transplanting mechanism 4, and the transplanting mechanism 4 will plant the seedlings vertically in the hole that was just dug. During this process, no manual transplanting operation is required, which saves time and effort.

[0046] The feeding mechanism 1 is fixed with a mounting frame 2, which is connected to the traction device for driving the device to move. The traction device can be a tractor or the like, which can drive the device to move for planting. The traction device also needs to be equipped with a lifting device for driving the device to lift and lower, so as to carry out the digging and transplanting operation. The lifting device can be a hydraulic cylinder or a mechanical arm or the like.

[0047] In the above technical solution, in order to ensure that the seedlings in the feeding mechanism 1 can fall into the transplanting mechanism 4 in sequence and accurately for subsequent transplanting operations, the specific structure and operation are as follows.

[0048] Reference Figures 2-4 In a preferred embodiment, the feeding mechanism 1 includes a first housing 101, a first drive gear 102 is provided on the edge of the first housing 101, a gear disk 103 is rotatably connected to the inner surface of the first housing 101, the gear disk 103 meshes with the first drive gear 102, a plurality of sets of placement channels 104 are arranged around the surface of the gear disk 103, seedlings are linearly arranged in the placement channels 104, and a pushing component is fixed on the outer wall of the first housing 101. The pushing component is used to push the seedlings in the placement channels 104 to the opening 107 and fall into the transplanting mechanism 4.

[0049] The material pushing assembly includes a material pushing cylinder 105 fixed to the outer wall of the first housing 101, and a material pushing plate 106 is fixedly connected to the telescopic end of the material pushing cylinder 105.

[0050] In this embodiment, the seedlings to be transplanted can be arranged in a series of placement channels 104. The pushing cylinder 105 of the pushing component can drive the pushing plate 106 to extend into a single placement channel 104, pushing the arranged seedlings one by one into the opening 107 and vertically falling into the transplanting mechanism 4. As the seedlings in a set of placement channels 104 are pushed out, the first drive gear 102 will rotate through the drive of the motor, thereby driving the gear disk 103 to rotate at a certain angle, so that another set of placement channels 104 is aligned with the pushing cylinder 105, and then the next round of transplanting operation is carried out.

[0051] It is worth noting that because the saplings have a soil clump at the bottom, they can be placed stably in the storage channel 104.

[0052] In the above technical solution, the transplanting of seedlings requires digging holes and loosening the soil on the ground, which we achieve through the following structure.

[0053] Reference Figures 2-7 In a preferred embodiment, the swirl mechanism 3 includes a second housing 301 rotatably connected to the lower surface of the first housing 101. A second drive gear 302 is fixed to the edge of the lower surface of the first housing 101. The second drive gear 302 meshes with the tooth groove on the outer wall of the second housing 301. A plurality of digging components 303 are movably connected to the inner ring of the second housing 301. A drive assembly for driving the digging components 303 to gather and disperse is provided inside the second housing 301.

[0054] In this embodiment, during the digging process, the lifting device first moves the entire device downward, so that the digging component 303 contacts the ground. Then, the second drive gear 302 rotates through the drive of the motor, thereby driving the second housing 301 and the digging component 303 to rotate, thereby digging the soil. While digging, the drive component can drive the digging component 303 to spread outward, thereby further expanding the diameter of the digging pit, and at the same time pushing the diggered soil outward.

[0055] The drive assembly includes a gear ring 304 rotatably connected inside the second housing 301. The gear ring 304 is driven to rotate by a third drive gear 305. Several sets of digging components 303 are movably connected to the gear ring 304. The third drive gear 305 of the drive assembly can be rotated by a motor, thereby causing the meshing gear ring 304 to rotate. While rotating, the spacing of the digging components 303 movably connected to its inner wall changes.

[0056] Furthermore, the excavating component 303 includes a connecting strip 3031 rotatably connected to the inner wall of the toothed ring 304. A soil-pushing blade 3032 is provided on the lower surface of the connecting strip 3031. The outer surface of the soil-pushing blade 3032 has an arc-shaped structure. The arc-shaped structure of the soil-pushing blade 3032 can better push the soil outward and improve the digging effect. In addition, the connecting strip 3031 is slidably connected to the inner bottom surface of the second housing 301, thereby ensuring the stability of the excavating component 303.

[0057] The soil-removing blade 3032 has a pointed tip 3033 at its lower end. In the initial state, the lower ends of the pointed tips 3033 are in contact with each other, ensuring that the gathered pointed tips 3033 can increase the pressure in the early stage of digging, thus improving the effect of digging in the early stage. The transplanting mechanism 4 located at the center of the soil-removing blade 3032 will not come into contact with the soil and stones first, thus protecting the transplanting mechanism 4. At the same time, as the digging work progresses, the soil-removing blade 3032 will slowly spread outward through the drive component to improve the effect of subsequent digging and soil removal, and also loosen the soil.

[0058] In the above technical solution, to improve the transplanting effect of the seedlings, we achieve this through the following structure.

[0059] Reference Figures 2-4 , Figure 6 and Figure 8 In a preferred embodiment, the transplanting mechanism 4 includes two sets of transplanting tubes 401 movably disposed on the lower surface of the first housing 101. The upper end of the transplanting tube 401 is funnel-shaped and corresponds to the opening 107, and the lower end of the transplanting tube 401 is tapered. A drive motor 402 is disposed on the lower surface of the first housing 101. The drive motor 402 drives the two sets of transplanting tubes 401 to open and close through a bidirectional lead screw 403 at the output end.

[0060] In this embodiment, a group of saplings pushed by the pushing cylinder 105 will be located in the two sets of transplanting tubes 401. After the shoveling mechanism 3 shovels the soil, the drive motor 402 of the transplanting mechanism 4 will drive the bidirectional lead screw 403 to rotate, thereby causing the two sets of transplanting tubes 401 to move in opposite directions, so that the saplings inside fall down into the pit. The traction device can be equipped with a soil covering device. As the traction device continues to move forward, the soil covering device can re-cover the planted sapling with the soil dug out in the center. The soil covering device can be a relatively inclined turntable or a scraper, etc., which is the prior art and will not be described in detail here.

[0061] Furthermore, a piston rod 404 is fixedly connected to one side of one of the transplanting pipes 401. The piston rod 404 is connected to the material box 405. A spray nozzle 406 connected to the piston rod 404 is opened on the inner wall of the lower end of the transplanting pipe 401.

[0062] In this embodiment, during the closing process of the transplanting tube 401, one set of transplanting tubes 401 pulls the piston rod 404 and draws the fertilizer solution in the feed box 405 into the piston rod 404. As the transplanting tube 401 opens, it pushes the piston rod 404 to spray the drawn fertilizer solution from the spray nozzle 406 at the lower end, thereby fertilizing the planting location to improve the subsequent growth effect of the vegetation. This piston structure is existing technology and will not be described in detail here.

[0063] In this embodiment, the saplings to be transplanted are arranged sequentially in several sets of placement channels 104. The pushing cylinder 105 of the pushing component can drive the pushing plate 106 to extend into a single set of placement channels 104, pushing the arranged saplings one by one into the opening 107 and vertically falling into the transplanting tube 401 of the transplanting mechanism 4. Then, the lifting device first moves the entire device downward, so that the digging component 303 contacts the ground. Subsequently, the second drive gear 302 rotates through the drive of the motor, thereby driving the second housing 301 and... The digging component 303 rotates to dig the soil. While digging the pit, the drive component can drive the digging component 303 to spread outward, thereby further expanding the diameter of the pit. At the same time, the soil dug outward is pushed outward. Then, the drive motor 402 of the transplanting mechanism 4 drives the bidirectional lead screw 403 to rotate, thereby causing the two sets of transplanting tubes 401 to move in opposite directions, so that the seedlings inside fall down into the pit for transplanting. Finally, the transplanting of eucalyptus seedlings for the entire vegetation restoration is completed. During the process, no manual digging and transplanting is required, and the efficiency is effectively improved.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
