Description

Technical Field

[0001] This invention belongs to the field of seedling transplanting technology, specifically relating to a mangrove seedling transplanting device. Background Technology

[0002] Mangroves, as a key ecosystem distributed in the intertidal zone of tropical and subtropical coasts, play an irreplaceable role in wind and wave protection, carbon sequestration, water purification, and maintaining biodiversity. In recent years, large-scale artificial mangrove restoration projects have been widely carried out globally to address coastal erosion and ecological degradation. Among these efforts, seedling transplantation is one of the crucial steps determining the success or failure of restoration.

[0003] In traditional mangrove seedling transplantation, especially on deep silty mudflats, the "manual planting method" is commonly used. The operator holds the seedling and forcefully inserts its roots directly into the mud. While this method is simple and inexpensive, it has significant technical drawbacks: First, during insertion, the seedling's roots must overcome the immense shear resistance and adhesion of the mud, easily leading to root compression, stem abrasion, and even root bending or breakage, creating subtle "internal injuries." This mechanical damage severely disrupts the seedling's vascular tissue, affecting water and nutrient absorption and significantly reducing post-transplant survival rate and early growth vigor. Second, this method relies entirely on the operator's experience to control insertion depth and verticality, resulting in poor consistency and hindering standardized planting. Furthermore, manual planting is particularly difficult and inefficient on mudflats with slightly firm soil or containing debris.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0005] The purpose of this invention is to provide a mangrove seedling transplanting device to solve the problem that traditional manual planting easily causes mechanical damage to the roots and stems of seedlings.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A mangrove seedling transplanting device includes a high-pressure water gun integrated with a high-pressure water pump. A seedling support mechanism is mounted on the barrel of the high-pressure water gun. The support mechanism includes a mounting sleeve fixedly fitted onto the barrel and a clamping assembly for holding the seedling stem. The clamping assembly is mounted on the outer wall of the mounting sleeve. The mounting sleeve also has a support platform for supporting the seedling roots, located near the nozzle of the barrel. The mounting sleeve also has an ejection assembly for detaching the seedling from the support platform. The ejection assembly includes a sliding sleeve slidably fitted onto the mounting sleeve and a support tray hinged to the support platform. The top of the sliding sleeve has a drive plate for opening the clamping assembly, and the bottom of the sliding sleeve has a fixed plate for rotating the support tray. A movable connecting rod is provided between the fixed plate and the support tray. The lower end of the movable connecting rod is hinged to the support tray, and the upper end of the movable connecting rod is movably connected to the fixed plate. The top of the sliding sleeve also has a lifting rod for sliding the sliding sleeve along the mounting sleeve.

[0008] Furthermore, a first hinge seat is formed on the top of the side of the support platform away from the mounting sleeve. A first hinge shaft that mates with the first hinge seat is provided on the outer side of the support tray. A first torsion spring is provided between the first hinge shaft and the first hinge seat. The first torsion spring keeps the support tray in a horizontal supporting state when there is no external force. The structure is simple and the reset is reliable.

[0009] Furthermore, the fixed plate has a movable groove for the movable connecting rod to engage, and movable sliding grooves extending along the axis of the mounting sleeve are formed on both side walls of the movable groove. The upper end of the movable connecting rod has a movable shaft that mates with the movable sliding groove. A second hinge seat is formed on the top of the support plate near the mounting sleeve, and a second hinge shaft that mates with the second hinge seat is formed at the lower end of the movable connecting rod. The design of the movable sliding groove allows the movable shaft to slide within the groove first when the lifting rod is raised, delaying the ejection action, thus strictly achieving the sequential linkage of "opening the clamp first, then ejecting," avoiding interference.

[0010] Furthermore, the clamping assembly includes two symmetrically arranged arc-shaped clamping plates. A connecting plate, hinged to the mounting sleeve, is provided on the outer side of each arc-shaped clamping plate. A second torsion spring is provided at the hinge point between the connecting plate and the mounting sleeve to drive the two arc-shaped clamping plates to move closer together and clamp tightly. A flexible clamping pad is connected to the clamping surface of each arc-shaped clamping plate. The arc-shaped clamping plates, in conjunction with the second torsion spring, provide a stable clamping force, while the flexible clamping pad effectively protects the seedling stem epidermis and prevents injury.

[0011] Furthermore, both sides of the top of the drive plate are formed with guide slopes that can slide and engage with the inner side of the connecting plate; the height of the guide slopes is less than or equal to the length of the movable slide groove. The guide slopes can smoothly convert the vertical movement of the sliding sleeve into the radial opening movement of the clamping plate, and their height limitation ensures that the clamping action is completed before the ejection action.

[0012] Furthermore, the outer wall of the mounting sleeve is provided with a support block to support the drive plate, and a connecting guide rail is formed on the side of the drive plate near the mounting sleeve, which slides in cooperation with the support block. The cooperation between the support block and the connecting guide rail ensures the stability and straightness of the movement trajectory of the drive plate and the sliding sleeve, and prevents jamming.

[0013] Furthermore, two limiting grooves are formed on the outer wall of the mounting sleeve, and guide rods are provided within the limiting grooves. A limiting slider is formed on the inner wall of the sleeve to cooperate with the limiting grooves, and a guide hole is formed on the limiting slider to slide with the guide rods. A return spring is also fitted onto the guide rod, with one end abutting against the inner top wall of the limiting groove and the other end abutting against the top of the sleeve. The cooperation between the limiting slider and the guide rod further ensures the precise guidance of the sleeve's movement. The return spring can automatically push the sleeve and lifting rod back to their initial position after operation, facilitating quick re-operation and improving efficiency.

[0014] Furthermore, the high-pressure water gun is also equipped with a water inlet head; the water inlet head is connected to the high-pressure water gun via a flexible hose; the flexible hose is also equipped with a float. The water inlet head can draw water from the mudflats and pits on-site, and the float can ensure that the water inlet head always floats on the water surface, preventing the intake of bottom sediment and ensuring water supply.

[0015] Furthermore, the water inlet head includes a housing and a filter element; the housing has a conical shell and a connecting shell located at the bottom of the conical shell, the filter element includes a conical filter housing and a connecting ring located at the bottom of the conical filter housing, the connecting shell and the connecting ring are connected by threads, and multiple filter holes are distributed on the conical filter housing; a filter screen is also provided at the bottom of the conical filter housing. The conical filter housing can effectively intercept most suspended particles and impurities in the water, preventing clogging of the high-pressure water pump and nozzles. The conical design and threaded connection facilitate quick disassembly and cleaning.

[0016] Furthermore, the bottom of the conical filter housing is provided with an annular counterweight, and the outer wall of the counterweight has multiple anti-slip grooves. The advantages are: the counterweight helps the inlet head maintain a stable position in the water, and the anti-slip grooves facilitate hand gripping and disassembly, improving operational convenience.

[0017] With the above-described structure, the mangrove seedling transplanting device of the present invention has the following advantages compared with the prior art:

[0018] 1. This invention utilizes the water jets from a high-pressure water gun to create planting pits on the mudflats. The seedling roots are placed in a water-rich environment, reducing friction and compression resistance from the solid silt. This fundamentally avoids the mechanical damage to the seedling roots and stems caused by traditional planting methods, and can significantly improve the transplant survival rate.

[0019] 2. This invention utilizes the mechanical linkage of the sliding sleeve, drive plate, and movable connecting rod to automatically and reliably complete the two steps of "clamping and releasing" and "seedling ejection" in sequence via the lifting rod. The operation is simple and the action is precise, ensuring that the seedlings are released vertically and stably at the bottom of the pit. Attached Figure Description

Detailed Implementation

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0035] like Figures 1-12As shown, this invention relates to a mangrove seedling transplanting device, comprising a high-pressure water gun 1 integrating a high-pressure water pump. A seedling support mechanism is installed on the barrel 11 of the high-pressure water gun 1. The high-pressure water jet from the high-pressure water gun 1 creates planting pits on the mudflats. It should be noted that the high-pressure water jet from the high-pressure water gun 1 is a small-angle divergent stream, with a divergence angle of 10°-15°. Specifically, the support mechanism includes a mounting sleeve 2 fixedly fitted onto the barrel 11 and a clamping assembly 3 for holding the seedling stem. The clamping assembly 3 is installed on the outer wall of the mounting sleeve 2. The mounting sleeve 2 also has a support platform 21 for supporting the seedling roots. The support platform 21 is fixedly connected to the mounting sleeve 2 by welding or integral molding. The support platform 21 is located near the nozzle of the barrel 11. The nozzle is slightly higher than the barrel 11. The mounting sleeve 2 is also provided with an ejection assembly 4 that drives the seedling to detach from the support platform 21. The ejection assembly 4 includes a sliding sleeve 41 that is slidably fitted on the mounting sleeve 2 and a support tray 42 that is hinged to the support platform 21. The top of the support tray 42 is a downwardly concave arc surface, which facilitates better placement of the seedling's roots or soil ball. The top of the sliding sleeve 41 is provided with a drive plate 43 that drives the clamping assembly 3 to open. The bottom of the sliding sleeve 41 is provided with a fixing plate 44 that drives the support tray 42 to flip. A movable connecting rod 45 is also provided between the fixing plate 44 and the support tray 42. The lower end of the movable connecting rod 45 is hinged to the support tray 42, and the upper end of the movable connecting rod 45 is movably connected to the fixing plate 44. The top of the sliding sleeve 41 is also provided with a lifting rod 411 that drives the sliding sleeve 41 to slide along the mounting sleeve 2. A first hinge seat 211 is formed on the top of the support platform 21 on the side away from the mounting sleeve 2. A first hinge shaft 421 that mates with the first hinge seat 211 is provided on the outer side of the support tray 42. A first torsion spring is provided between the first hinge shaft 421 and the first hinge seat 211. Under the action of the first torsion spring, the support tray 42 can be kept in a horizontal support state when there is no external force, and a downward torque is provided during reset so that the support tray 42 can be reset smoothly. A movable groove for the movable connecting rod 45 to be inserted is formed on the fixed plate 44. Movable sliding grooves 441 extending along the axis of the mounting sleeve 2 are formed on the two side walls of the movable groove. A movable shaft 451 that mates with the movable sliding groove 441 is formed at the upper end of the movable connecting rod 45. A second hinge seat 422 is formed on the top of the support tray 42 on the side close to the mounting sleeve 2. A second hinge shaft 452 that mates with the second hinge seat 422 is formed at the lower end of the movable connecting rod 45. In this embodiment, the clamping assembly 3 includes two symmetrically arranged arc-shaped clamping plates 31. The outer side of the arc-shaped clamping plates 31 is provided with a connecting plate 311 that is hinged to the mounting sleeve 2. The hinge point between the connecting plate 311 and the mounting sleeve 2 is provided with a second torsion spring that drives the two arc-shaped clamping plates 31 to move closer together and clamp tightly. The second torsion spring provides a stable clamping force. In addition, in order to protect the seedling stem when clamping, the clamping surface of the arc-shaped clamping plates 31 is connected with a flexible pad 32, such as foamed rubber or silicone.

[0036] In this embodiment, guide ramps 431 are formed on both sides of the top of the drive plate 43, which can slide and engage with the inner side of the connecting plate 311; the height of the guide ramps 431 is less than or equal to the length of the movable slide groove 441. Support blocks 22 are provided on the outer wall of the mounting sleeve 2 to support the drive plate 43, and a connecting guide rail 432 that slides and engages with the support block 22 is formed on the side of the drive plate 43 near the mounting sleeve 2. When the slide sleeve 41 is pulled upwards, the drive plate 43 rises accordingly, and the guide ramps 431 on both sides contact and push the inner side of the two connecting plates 311 of the clamping assembly 3, forcing the connecting plates 311 to rotate outwards around the hinge point, thereby overcoming the force of the second torsion spring and causing the two arc-shaped clamping plates 31 to open and release the clamping of the seedling. The support blocks 22 on the mounting sleeve 2 cooperate with the connecting guide rail 432 on the back of the drive plate 43 to provide auxiliary support for the vertical movement of the drive plate 43. This ensures the stability and straightness of the movement trajectory of the drive plate 43 and prevents jamming.

[0037] In this embodiment, two limiting grooves 23 are formed on the outer wall of the mounting sleeve 2. A guide rod 231 is provided in the limiting groove 23. A limiting slider 412 that cooperates with the limiting groove 23 is formed on the inner wall of the sliding sleeve 41. A guide hole 413 that slides with the guide rod 231 is formed on the limiting slider 412. A return spring 46 is also sleeved on the guide rod 231. One end of the return spring 46 is connected to the inner top wall of the limiting groove 23, and the other end is connected to the top of the sliding sleeve 41. The cooperation between the limiting slider 412 and the guide rod 231 further ensures the precise guidance of the movement of the sliding sleeve 41. The return spring 46 can automatically push the sliding sleeve 41 and the lifting rod 411 back to the initial position after operation, which facilitates the quick re-operation of the next operation and improves efficiency.

[0038] The overall linkage principle is as follows: In the initial state, the seedling's stem is clamped by the clamping component 3, and the roots are placed on the horizontal support tray 42. When planting is required, the operator pulls the lifting rod 411 upwards. The sliding sleeve 41 drives the drive plate 43 and the fixing plate 44 to move upwards together.

[0039] In the first stage, the guide slope 431 of the drive plate 43 pushes open the connecting plate 311, causing the clamping assembly 3 to open and the seedling stem to be released. At this time, since the movable shaft 451 at the upper end of the movable link 45 can slide freely within the movable slide groove 441 of the fixed plate 44 for a short period of time, the initial upward movement of the fixed plate 44 does not immediately drive the movable link 45 to move, and the support tray 42 remains stationary. This achieves "first-open clamp".

[0040] In the second stage, after the movable shaft 451 slides to the top of the movable chute 441, the fixed plate 44 continues to move upward, pulling the support tray 42 via the movable connecting rod 45. Since the outer side of the support tray 42 is hinged and fixed by the first hinge seat 211, under the pull of the movable connecting rod 45, the support tray 42 will flip upward around the hinge point, thereby lifting (pushing out) the roots of the seedlings on it, causing them to detach from the support tray 42 and fall vertically into the pit bottom below, which has been flushed out by high-pressure water. This completes the "rear push-out".

[0041] After release, release the lifting rod 411. Under the action of the return spring 46, the sliding sleeve 41, drive plate 43, and fixing plate 44 automatically reset and move downward. The downward movement of the fixing plate 44 first presses the support tray 42 back to the horizontal position through the movable connecting rod 45. Then, the drive plate 43 disengages from the connecting plate 311, and the clamping assembly 3 closes again under the action of the second torsion spring, waiting to clamp the next seedling.

[0042] In this embodiment, the high-pressure water gun 1 is also equipped with a water inlet head 6; the water inlet head 6 is connected to the high-pressure water gun 1 via a flexible hose 7; a float 8 is also provided on the flexible hose 7. The water inlet head 6 can draw water from the mudflats and puddles on-site, and the float 8 ensures that the water inlet head 6 always floats on the water surface, preventing the intake of bottom sediment and ensuring water supply. The water inlet head 6 includes a housing 61 and a filter element 62; the housing 61 has a conical shell 611 and a connecting shell 612 located at the bottom of the conical shell 611, the filter element 62 includes a conical filter shell 621 and a connecting ring 622 located at the bottom of the conical filter shell 621, the connecting shell 612 and the connecting ring 622 are connected by threads, and multiple filter holes 6211 are formed on the conical filter shell 621; a filter screen 6212 is also provided at the bottom of the conical filter shell 621. The conical filter shell 621 can effectively intercept most suspended particles and impurities in the water, preventing the high-pressure water pump and nozzle from clogging. The conical design and threaded connection facilitate quick disassembly and cleaning. The bottom of the conical filter housing 621 is also provided with an annular counterweight 623, and the outer wall of the counterweight 623 has multiple anti-slip grooves 6231. The counterweight 623 can keep the inlet head 6 stable in the water, and the anti-slip grooves 6231 make it easy to grip and disassemble by hand, improving the convenience of operation.

[0043] The method of using this invention is as follows: Place the water inlet head 6 into the mudflat water pit, start the high-pressure water gun 1, and vertically align the gun barrel 11 with the planting point, using the high-pressure water flow to create a planting pit. Keeping the gun barrel 11 in place, pull up the lifting rod 411, and the linkage mechanism will act sequentially to release the seedlings without damage to the bottom of the pit. Subsequently, slowly close the water valve and vertically lift the device. The surrounding silt will naturally backfill after the surface tension of the water disappears, wrapping the seedling roots and completing one planting cycle.

[0044] The foregoing has provided a detailed description of a mangrove seedling transplanting device provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
