Description

Technical Field

[0001] This invention relates to the field of planting, specifically to a device for rapid planting of flowering shrubs. Background Technology

[0002] In landscaping projects, the planting of flowering shrubs generally relies on manual labor. Workers must complete multiple steps in sequence, including digging holes, transporting saplings with root balls, placing them in the holes, straightening the plants, backfilling the soil, and tamping it down. This method is labor-intensive, inefficient, and significantly affected by human factors. It's difficult to ensure the verticality of the saplings, leading to them being crooked. Inconsistent planting depths, whether too deep or too shallow, also affect the survival rate. In large-scale planting scenarios, manual planting is slow and inconsistent, failing to meet the high efficiency, standardization, and high quality requirements of modern landscaping construction.

[0003] A currently published Chinese patent authorization announcement number CN117859611B discloses a shrub arrangement planting auxiliary device and planting method, including a transport vehicle that can move along the length of the roadside on a reference plane and can carry soil and shrubs; a synchronous soil spreading mechanism that is detachably connected to the transport vehicle and can move synchronously with the transport vehicle on the reference plane; the synchronous soil spreading mechanism includes a first movable frame that can span over two adjacent roadside edges, with a long strip nozzle installed below it, the height of the long strip nozzle being greater than the height of the roadside edge; the long strip nozzle is connected to the outlet of a delivery pipe, and the inlet of the delivery pipe extends into the soil of the transport vehicle, enabling the transport of soil to the long strip nozzle; and a compensating planting mechanism that can move on the reference plane and is connected to the synchronous soil spreading mechanism via a first telescopic drive motor and can move relative to the synchronous soil spreading mechanism, with the direction of movement parallel to the length of the roadside edge.

[0004] According to the aforementioned patent, the relative movement of the synchronous soil spreading mechanism and the compensating planting mechanism enables the digging and planting to be partially stationary during the movement of the transport vehicle. Combined with preset speed and telescopic drive control, it automatically completes the digging of holes at equal intervals, the placement of shrubs and the backfilling of soil.

[0005] However, although holes were pre-dug at equal intervals before planting, they are prone to collapse during the subsequent planting process due to loosening of the surrounding soil, resulting in shallower holes. The aforementioned patent lacks support for the backfill soil, making it difficult to maintain a uniform planting depth after the shrubs are placed, affecting root development and survival rate, and hindering standardized mass planting. Therefore, there is a need for a rapid planting device for flowering shrubs that ensures rapid planting while also providing hole protection and automatic backfilling functions. Summary of the Invention

[0006] To address the problems existing in the prior art, a rapid planting device for flowering shrubs is provided. By unfolding the supporting pot, the flowering shrub is planted. The inner support rod immediately extends and abuts against the inner side of the semi-ring shell to prevent it from closing prematurely. The supporting shell thereby expands the pit before backfilling the soil, ensuring consistent planting depth and reliable backfilling, preventing the flowering shrub from tipping over, and achieving continuous and efficient planting.

[0007] To address the problems of existing technologies, this invention provides a rapid planting device for flowering shrubs, installed on a transport vehicle, for automatically planting pre-set flowering shrubs into pre-dug, equally spaced planting pits. The device includes a height-adjustable support frame with two symmetrically arranged fixed discs, a rotating planting assembly positioned between the two fixed discs, a rotating main shaft rotatably connected to the fixed discs, and rotating discs symmetrically arranged on both sides of the rotating main shaft. Multiple support trays for placing the flowering shrubs are evenly distributed along the circumference between the two rotating discs. Each support tray consists of two symmetrical semi-annular shells, which are movable along the axis of the rotating main shaft. Each rotating disc is equipped with a support tray for placing the flowering shrubs. The guide shaft, which is slidably connected to the semi-ring shell, ensures that the supporting material basin remains open upwards due to its own weight during the rotation of the rotating disk. Each rotating disk has an unfolding structure at its lowest point, which includes a horizontal push plate and a horizontal driver mounted on a fixed disk. The end of the horizontal push plate near the rotating disk has a locking part. Each semi-ring shell has a mating part on both sides that can cooperate with the corresponding locking part. A support shell is fixed at the bottom of each horizontal push plate. The support shell is coaxially arranged with the supporting material basin located at the lowest point. When the support shell is inserted into the planting pit and moves outward synchronously with the semi-ring shell, the soil in the pit is pushed outward.

[0008] Preferably, magnetic blocks are provided on both sides of the two semi-annular shells to maintain the closed state of the material support basin by attracting each other between the two magnetic blocks. A non-magnetic guide rod is fixed on one of the magnetic blocks, which passes vertically through the other magnetic block and is slidably connected to it, to guide the lateral opening and closing of the semi-annular shell.

[0009] Preferably, the lower half of the semi-annular shell has an extension shaft extending vertically outward from its side. The end of the extension shaft is provided with the docking part. The docking part is a protruding structure with a diameter larger than that of the extension shaft. The snap-fit ​​part is a snap-fit ​​block structure that snaps into the extension shaft. The snap-fit ​​part is located inside the docking part and can push the docking part from the inside out.

[0010] Preferably, an extension plate is fixedly extended outward on the rotating disk for rotational connection of each guide shaft, and a compression spring sleeved on the guide shaft is provided between the extension plate and the semi-annular shell to provide a restoring elastic force after the material support basin is unfolded.

[0011] Preferably, a vertical push plate and a vertical driver are provided on the fixed plate at the position corresponding to the horizontal push plate. The horizontal driver is installed on the vertical push plate. A rod extends vertically outward from the vertical push plate, passes through the horizontal push plate, and slides with it. When the material support wheel rotates to the lowest point and drives the horizontal push plate upward, the locking part and the extension shaft are in a locking state.

[0012] Preferably, a rubber block is provided on the horizontal push plate near the snap-fit ​​part, and a pressure sensor is provided on the bottom of the horizontal push plate through its surface and connected to the rubber block. The pressure sensor is electrically connected to both the horizontal drive and the vertical drive.

[0013] Preferably, each rotating disk is provided with an inner support rod and an inner support driver at the position corresponding to each material support basin. The inner support rod is arranged radially along the rotating disk and is used to temporarily lock the position of the semi-ring shell after the material support basin is unfolded. When the material support basin rotates to the lowest point, its opening is in the position directly opposite the corresponding inner support rod.

[0014] Preferably, the support shell has an arc-shaped plate structure, and the two support shells are arranged opposite each other in the rotation direction of the material support basin, with a gap between them for the material support basin to pass through.

[0015] Preferably, the height-adjustable bracket includes a vehicle side panel and an outer frame. The vehicle side panel is fixedly installed on the transport vehicle and has two guide rails symmetrically arranged along its length. The outer frame is provided with a slider that slides with the guide rails. The rotating planting assembly is installed inside the outer frame and moves up and down along the guide rails with the outer frame to achieve height adjustment.

[0016] Preferably, an eccentric ring is rotatably provided on the fixed plate near the side panel of the vehicle. The eccentric ring is eccentrically positioned with respect to the rotating disk. A roller is provided on the corresponding fixed plate to support the inner side of the eccentric ring to roll. A stabilizing rod is rotatably connected between the eccentric ring and each guide shaft to suppress shaking during the rotation of the material basin.

[0017] The advantages of this application compared to the prior art are: 1. This invention uses a height-adjustable bracket to lower the entire rotating planting assembly, aligning the lowest supporting pot with the supporting shell in the pre-dug planting pit. The vertical actuator first pushes the vertical push plate upward, and the horizontal push plate rises accordingly. Its locking part contacts the protrusion at the end of the extension shaft of the semi-ring shell. Then, the locking part pushes the two semi-ring shells from the inside out to separate synchronously along the guide shaft, causing the supporting pot to unfold and the flowering shrub to fall into the pit.

[0018] At the same time, the supporting shell moves outward to expand the pit walls and prevent collapse. After planting is completed, the height-adjustable bracket raises the overall structure, the rotating main shaft moves one step forward, and the next support pot is precisely positioned, entering the next planting cycle, realizing fully automatic and continuous planting operations.

[0019] 2. This invention utilizes radial inner support rods controlled by an inner support driver, positioned on a rotating disk for each supporting material pot. These rods extend immediately after the supporting material pot expands and abut against the inner side of the semi-ring shell, effectively preventing the compression spring from prematurely closing the semi-ring shell. This temporary locking ensures that the supporting shell can first expand the pit outwards and then stably move back to achieve uniform soil backfilling, avoiding obstruction of backfilling or compression of flowering shrubs due to premature repositioning of the supporting material pots.

[0020] After backfilling is completed, the inner support rods automatically retract, releasing the limit switch. The semi-ring shell quickly closes and resets under the action of the compression spring, restoring its support capacity for the next flowering shrub. This ensures consistent planting depth and backfilling efficiency, prevents flowering shrubs from tipping over, and improves the continuity and survival rate of automated planting.

[0021] 3. This invention sets an eccentric ring on the fixed disk that is eccentrically arranged with respect to the rotating disk, and connects the eccentric ring to the guide shaft of each material support basin via a stabilizing rod. During rotation, the non-circular trajectory of the eccentric ring drives the stabilizing rod to generate coordinated swing, applying a dynamic radial constraint force to the guide shaft. This effectively suppresses the radial swaying and wobbling caused by inertia and vibration when the material support basin rotates, unfolds, or resets, ensuring the stability of the semi-ring shell's motion trajectory.

[0022] Meanwhile, the rollers support the inner side of the eccentric ring to roll, reducing frictional resistance, ensuring smooth operation, and improving the structural rigidity and operational reliability of the rotary planting assembly in continuous operation, thus providing a guarantee for rapid planting.

[0036] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0037] See Figures 1-6As shown, a rapid planting device for flowering shrubs is installed on a transport vehicle for automatically planting pre-set flowering shrubs into pre-dug, equally spaced planting pits. It includes a height-adjustable support 1 with two symmetrically arranged fixed discs 11, and a rotating planting assembly 2 positioned between the two fixed discs 11. The assembly includes a rotating main shaft 21 rotatably connected to the fixed discs 11 and rotating discs 22 symmetrically arranged on both sides of the rotating main shaft 21. Multiple support basins 3 for placing the flowering shrubs are evenly distributed along the circumference of the two rotating discs 22. Each support basin 3 consists of two symmetrical semi-annular shells 31, which can move along the axis of the rotating main shaft 21. Each rotating disc 22 is provided with a guide shaft slidably connected to the corresponding semi-annular shell 31. 221. During the rotation of the rotating disk 22, the supporting material basin 3 is always in an open-facing state due to its own weight. Each rotating disk 22 has an unfolding structure 4 at its lowest point. The unfolding structure 4 includes a horizontal push plate 41 and a horizontal driver 5 set on the fixed disk 11. The end of the horizontal push plate 41 near the rotating disk 22 has a snap-fit ​​part 411. Each half-ring shell 31 has a docking part 412 on both sides that can cooperate with the corresponding snap-fit ​​part 411. Each horizontal push plate 41 has a fixed support shell 32 at its bottom. The support shell 32 is coaxially arranged with the supporting material basin 3 at the lowest point. When the support shell 32 is inserted into the planting pit and moves outward synchronously with the half-ring shell 31, the soil in the pit is in a state of being pushed outward.

[0038] Before the planting of flowering shrubs begins, the pre-placed flowering shrubs with soil balls are placed sequentially into multiple support pots 3 of the rotating planting assembly 2. This device is installed on a transport vehicle and travels with the vehicle to the pre-dug, evenly spaced planting pits.

[0039] During planting, the height-adjustable bracket 1 first drives the overall structure to descend, aligning the support pot 3 located at the lowest point of the rotating planting assembly 2 and the supporting shell 32 below it with the current planting pit. At this time, the two supporting shells 32 are simultaneously inserted into the pit and are coaxial with the support pot 3.

[0040] Subsequently, the unfolding structure 4 is activated: the horizontal driver 5 on the fixed disk 11 pushes the horizontal push plate 41 to move horizontally along the axis of the rotating disk 22, and the locking part 411 at the end of the horizontal push plate 41 engages with the docking parts 412 on both sides of the semi-ring shell 31. As the horizontal push plate 41 moves outward, the locking part 411 drives the two semi-ring shells 31 to slide outward synchronously along the axis of the rotating main shaft 21, thereby unfolding the supporting pot 3, and the flowering shrubs inside fall into the planting pit under the action of gravity.

[0041] During this process, the supporting shell 32 and the semi-ring shell 31 move outward in tandem, pushing the soil around the pit wall outward to form a temporary expanded pit space, preventing soil collapse from affecting the planting depth. After the flowering shrub is released, the height-adjustable bracket 1 drives the entire rotating planting assembly 2 to rise upward and detach it from the planting area. At the same time, the rotating main shaft 21 rotates one work position angle, so that the next support pot 3 containing the flowering shrub rotates accurately to the lowest point, ready for the next planting.

[0042] Since each supporting pot 3 is slidably connected to the rotating disk 22 via the guide shaft 221 and always keeps its opening facing upwards by its own weight, the flowering shrubs can be stably supported and will not spill even during rotation. The entire process relies on the rotary layout and mechanical linkage unfolding structure 4 to achieve automatic planting of flowering shrubs as the transport vehicle moves intermittently, without the need for manual intervention in placing seedlings or filling soil, thus improving work efficiency.

[0043] See Figures 5-9 As shown, magnetic blocks 311 are provided on both sides of the two semi-annular shells 31 to maintain the closed state of the material support basin 3 by attracting each other through the two magnetic blocks 311. A non-magnetic guide rod 312 is fixed on one of the magnetic blocks 311, which passes vertically through the other magnetic block 311 and is slidably connected to it, to guide the lateral opening and closing of the semi-annular shell 31.

[0044] When the support basin 3 is in the closed state, the magnetic blocks 311 set on the opposite sides of the two semi-ring shells 31 attract each other due to magnetic force, so that the two semi-ring shells 31 fit tightly together and stably support the flowering shrubs inside.

[0045] When the planting action is initiated and the unfolding structure 4 pushes the semi-ring shell 31 to separate laterally, the two magnetic blocks 311 are pushed apart from each other. The non-magnetic guide rod 312 on one semi-ring shell 31 slides along the center hole of the corresponding magnetic block 311 on the other semi-ring shell 31, which plays a guiding role and ensures that the two semi-ring shells 31 unfold outward smoothly and symmetrically along the axis of the rotating main shaft 21, avoiding deviation or jamming.

[0046] After the flowering shrubs are released, during the reset phase, the attraction between the magnetic blocks 311 comes into play again, achieving automatic closure and restoring the supporting state, preparing for the next loading and planting.

[0047] See Figures 10-12 As shown, an extension shaft 4121 extends vertically outward from the side of the lower half of the semi-annular shell 31. The end of the extension shaft 4121 is provided with the docking part 412. The docking part 412 is a convex structure with a diameter larger than that of the extension shaft 4121. The locking part 411 is a locking block structure that locks with the extension shaft 4121. The locking part 411 is located inside the docking part 412 and can push the docking part 412 from the inside out.

[0048] When the supporting basin 3 rotates to the lowest planting position, the extension shaft 4121, which extends vertically outward from the lower half of its semi-annular shell 31, reaches the corresponding position of the unfolding structure 4. At this time, the locking part 411 provided on the horizontal push plate 41, that is, the locking block structure located inside the docking part 412, aligns with the extension shaft 4121 and is embedded in its outer periphery.

[0049] When the transverse drive 5 is activated, pushing the transverse push plate 41 outward, the locking block structure abuts against and pushes the protruding head structure at the end of the extension shaft 4121 from the inside out, thereby driving the entire semi-ring housing 31 to slide outward synchronously along the axial direction. Since both semi-ring housings 31 are engaged with the corresponding locking parts 411 through their respective extension shafts 4121, they separate symmetrically under the transverse pushing action, realizing the reliable unfolding of the supporting pot 3 and ensuring that the flowering shrub falls smoothly into the planting pit.

[0050] See Figures 6-12 As shown, an extension plate 222 is fixedly extended outward on the rotating disk 22 for rotating connection of each guide shaft 221. A compression spring 313 sleeved on the guide shaft 221 is provided between the extension plate 222 and the semi-annular shell 31 to provide a restoring elastic force after the material basin 3 is unfolded.

[0051] When the material support basin 3 is in the closed state, the semi-annular shell 31 is slidably mounted on the rotating disk 22 between the outwardly extending extension plate 222 via the guide shaft 221, and the compression spring 313 sleeved on the guide shaft 221 is pre-pressed between the extension plate 222 and the inner side of the semi-annular shell 31.

[0052] When the unfolding structure 4 drives the two semi-ring shells 31 to separate laterally outward along the guide shaft 221 and release the flowering shrub, the elastic potential energy stored in the compression spring 313 is converted into a restoring force. After the planting action is completed and the unfolding force is removed, the compression spring 313 pushes the semi-ring shells 31 to slide inward along the guide shaft 221, causing them to automatically return to the initial closed position and restore the supporting state for the next flowering shrub, thereby achieving reliable reset and recycling of the supporting pot 3.

[0053] See Figures 6-12 As shown, a vertical push plate 42 and a vertical driver 6 are provided on the fixed plate 11 at the position corresponding to the horizontal push plate 41. The horizontal driver 5 is installed on the vertical push plate 42. A rod 421 extends vertically outward on the vertical push plate 42, passes through the horizontal push plate 41, and slides with it. When the material support basin 3 rotates to the lowest point and drives the horizontal push plate 41 upward, the locking part 411 and the extension shaft 4121 are in a locking state.

[0054] The transverse actuator 5 includes a push block 51 and a connecting rod 52. The push block 51 is slidably mounted on the vertical push plate 42. The two ends of the connecting rod 52 are respectively hinged to the push block 51 and the transverse push plate 41. The vertical push plate 42 is provided with an electric push rod 53 for driving the push block 51 to slide vertically.

[0055] When the electric push rod 53 drives the push block 51 to move down, the push block 51 pushes the connecting rod 52 to unfold outward. At this time, the vertical force of the push block 51 is converted into the lateral force of the horizontal push plate 41 to unfold, thereby realizing the unfolding of the semi-annular shell 31.

[0056] The vertical actuator 6 is an electromagnetic drive structure, consisting of a strip-shaped fixed electromagnet 61 and a strip-shaped movable electromagnet 62. The fixed disk 11 is provided with a vertical guide groove for the vertical push plate 42 to slide. The strip-shaped fixed electromagnet 61 is fixedly connected to the vertical guide groove, and the strip-shaped movable electromagnet 62 is fixedly connected to the vertical push plate 42.

[0057] The vertical actuator 6 can also be replaced by a controllable linear drive structure such as an electric push rod 53 or a cylinder.

[0058] When the material support tray 3 rotates with the rotating disk 22 to the lowest planting position, the vertical drive 6 on the fixed disk 11 is activated, driving the vertical push plate 42 fixed thereto to slide upward along the vertical guide groove. During the upward movement of the vertical push plate 42, the horizontal drive 5 installed on it is raised synchronously, so that the locking part 411 on the horizontal push plate 41 mates with the extension shaft 4121 of the semi-ring housing 31 and enters the locking state.

[0059] Subsequently, the electric push rod 53 on the vertical push plate 42 drives the push block 51 to move downward. The push block 51 converts the vertical motion into a lateral thrust through the hinged connecting rod 52, pushing the horizontal push plate 41 to move outward horizontally. The horizontal push plate 41 then drives the locking part 411 to push the docking part 412 from the inside out, so that the two semi-annular shells 31 separate synchronously along the guide shaft 221, completing the unfolding of the supporting basin 3 and the release of the flowering shrubs.

[0060] The entire process ensures precise and reliable operation through step-by-step linkage of vertical positioning and horizontal expansion.

[0061] See Figure 6 and Figure 11 As shown, a rubber block 4111 is provided on the horizontal push plate 41 near the snap-fit ​​part 411. A pressure sensor 4112 is provided at the bottom of the horizontal push plate 41, passing through its surface and connected to the rubber block 4111. The pressure sensor 4112 is electrically connected to both the horizontal driver 5 and the vertical driver 6.

[0062] When the material support basin 3 rotates to its lowest point and the vertical drive 6 pushes the horizontal push plate 41 to its position, the locking part 411 on the horizontal push plate 41 approaches the extension shaft 4121 of the semi-annular housing 31. At this time, the rubber block 4111 first contacts the protruding structure at the end of the extension shaft 4121 and undergoes elastic compression. The deformation of the rubber block 4111 is transmitted to the pressure sensor 4112 connected to it. The pressure sensor 4112 detects the contact force in real time and feeds the signal back to the control system.

[0063] When the pressure reaches the preset threshold, it indicates that the locking part 411 has been accurately aligned and reliably docked. The control system then triggers the lateral actuator 5 to start, while ensuring that the vertical actuator 6 maintains its current position. If the pressure is abnormal, the lateral movement is paused to avoid misoperation and ensure the safety and accuracy of the unfolding operation.

[0064] See Figures 6-8 and Figure 12 As shown, each rotating disk 22 is provided with an inner support rod 33 and an inner support driver 7 at the position corresponding to each material support basin 3. The inner support rod 33 is arranged radially along the rotating disk 22 and is used to temporarily lock the position of the semi-annular shell 31 after the material support basin 3 is unfolded. When the material support basin 3 rotates to the lowest point, its opening is in the position directly opposite the corresponding inner support rod 33.

[0065] The rotating disk 22 is provided with a sleeve 331 for guiding the inner support rod 33 to move radially. The inner support drive 7 is an electromagnetic drive structure, consisting of a block-shaped fixed electromagnet 71 and a block-shaped movable electromagnet 72. The block-shaped fixed electromagnet 71 is fixedly connected to the rotating disk 22, and the block-shaped movable electromagnet 72 is fixedly connected to the inner support rod 33.

[0066] The internal support driver 7 can also be replaced by a controllable linear drive structure such as an electric push rod 53 or a cylinder.

[0067] When the supporting basin 3 rotates with the rotating disk 22 to the lowest planting position and completes its unfolding, its opening is directly opposite the inner support rod 33 located at the corresponding position on the rotating disk 22. At this time, the inner support driver 7 is activated, driving the inner support rod 33 to extend outward along the radial path defined by the rod sleeve 331, so that it abuts against the inner side of the semi-annular shell 31, effectively preventing the semi-annular shell 31 from prematurely rebounding and closing under the action of the compression spring 313, thereby maintaining its unfolded state.

[0068] In this locked state, the support shell 32 first expands the pit outward, then moves inward to push the soil evenly back to the roots of the flowering shrubs for backfilling. After backfilling is completed, the inner support drive reverses its direction, and the inner support rod 33 retracts into the sleeve 331 under the action of the restoring force, releasing the restriction on the semi-ring shell 31, allowing it to automatically close under the push of the compression spring 313, restoring the supporting state and preparing for the next cycle.

[0069] See Figure 6 As shown, the support shell 32 has an arc-shaped plate structure. The two support shells 32 are arranged opposite each other in the rotation direction of the material support basin 3, and a gap is left between them for the material support basin 3 to pass through.

[0070] During the operation of the rotating planting assembly 2, the supporting tray 3 rotates continuously in a circumferential direction along with the rotating disk 22. When the supporting tray 3 passes through a position other than the lowest point, it can smoothly pass through the gap between the two supporting shells 32, avoiding interference with the supporting shells 32. Only when the supporting tray 3 rotates precisely to the lowest planting position is the supporting shell 32 directly below it synchronously driven to participate in the operation. At other positions, the gap ensures that the supporting tray 3 can rotate freely and without obstruction, thereby ensuring the continuous and stable operation of the device.

[0071] See Figures 1-4 As shown, the height-adjustable bracket 1 includes a vehicle side panel 12 and an outer frame 13. The vehicle side panel 12 is fixedly installed on the transport vehicle and has two guide rails 121 symmetrically arranged along its length. The outer frame 13 is provided with a slider 131 that slides with the guide rails 121. The rotating planting assembly 2 is installed entirely inside the outer frame 13 and rises and falls along the guide rails 121 with the outer frame 13 to achieve height adjustment.

[0072] Before planting begins, the height-adjustable bracket 1 is securely installed on both sides of the transport vehicle via its side panels 12, and the rotating planting assembly 2 is integrated inside the outer frame 13. When the planting height needs to be adjusted, a drive mechanism, such as a hydraulic cylinder or an electric push rod 53, pushes the outer frame 13 up and down along the guide rail 121, causing the entire rotating planting assembly 2 to rise and fall synchronously. During descent, the device precisely aligns with the depth of the pre-dug planting pit, ensuring that the support housing 32 can be smoothly inserted into the pit.

[0073] After planting is completed, the outer frame 13 moves upward and resets along the guide rail 121, providing sufficient clearance from the ground for the transport vehicle to move forward and for the next plant to be planted, ensuring planting accuracy and operational reliability.

[0074] See Figures 3-5 As shown, an eccentric ring 122 is rotatably mounted on a fixed disk 11 near the side panel 12 of the vehicle. The eccentric ring 122 is eccentrically mounted to the rotating disk 22. A roller 123 is provided on the fixed disk 11 to support the inner rolling of the eccentric ring 122. A stabilizing rod 124 is rotatably connected between the eccentric ring 122 and each guide shaft 221 to suppress shaking during the rotation of the material basin 3.

[0075] During the operation of the rotating planting assembly 2, the rotating disk 22 drives the supporting basin 3 to rotate continuously around the rotating main shaft 21. At this time, driven by the stabilizing rod 124, the eccentric ring 122 rotates synchronously with the rotating disk 22 and maintains stable rolling. When the supporting basin 3 rotates with the rotating disk 22, due to the eccentric trajectory of the eccentric ring 122, the stabilizing rod 124 swings in coordination, applying a dynamic constraint force to the guide shaft 221, effectively counteracting the radial sway and wobble caused by inertia or vibration during the rotation or unfolding and resetting of the supporting basin 3, and improving the synchronicity and smoothness of the movement of the semi-ring shell 31.

[0076] This invention achieves fully automated continuous planting of flowering shrubs in pre-dug pits through the coordinated action of a height-adjustable bracket 1, a rotating planting assembly 2, an unfolding structure 4, and a supporting shell 32. After the supporting pot 3 is precisely aligned, the vertical actuator 6 first completes the snap-fit ​​positioning between the snap-fit ​​part 411 and the docking part 412, while the horizontal actuator 5 simultaneously unfolds the semi-circular shell 31 to release the flowering shrubs, and the supporting shell 32 then expands outwards to prevent collapse.

[0077] After the flowering shrubs are planted, the inner support rod 33 extends immediately after the semi-ring housing 31 unfolds to lock the semi-ring housing 31, preventing it from closing prematurely due to the compression spring 313. This allows the support housing 32 to perform backfilling, ensuring complete and reliable backfilling. The inner support rod 33 automatically unlocks and resets after backfilling is complete. No manual intervention is required, improving planting efficiency.

[0078] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
