Description

Technical Field

[0001] This invention relates to the field of landscape construction technology, specifically to a device and method for transplanting trees for landscaping. Background Technology

[0002] Tree transplanting is a common operation in landscaping projects. Traditional transplanting methods rely heavily on manual digging and hoisting, which suffers from high labor intensity, low efficiency, easy damage to tree roots and trunks, high root ball breakage rate, and reduced survival rate. Existing mechanical transplanting devices typically only have simple clamping or digging functions, making it difficult to simultaneously ensure stable tree clamping, effective root cutting, and flexibility in different directions. Furthermore, the lack of cushioning during lifting and lowering often causes tree swaying or equipment impact; when cutting roots, the cutter struggles to gather lateral roots, resulting in incomplete cuts.

[0003] Therefore, there is an urgent need for an integrated, stable, and flexible transplanting device to improve the efficiency and survival rate of tree transplantation. Summary of the Invention

[0004] In view of this, the present invention provides a tree transplanting device and method for gardens to solve the technical problem that existing structures are difficult to balance operational stability and effective root cutting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A tree transplanting device for gardens includes: The underframe is configured to be towed by a towing device; A shifting mechanism, mounted on the base frame, is used to drive the actuator to rotate horizontally; A lifting mechanism, installed on the displacement mechanism, includes a lifting cylinder and a buffer support assembly connected in parallel to its side. The buffer support assembly is used to assist in supporting the telescopic rod of the lifting cylinder and is configured to provide damping when the telescopic rod descends, so as to reduce the retraction speed of the telescopic rod.

[0006] Furthermore, the garden tree transplanting device also includes: A clamping and limiting mechanism is connected to the front end of the telescopic rod, including clamping components and limiting components arranged vertically at intervals. The clamping components are used to hold the trunk of the tree, and the limiting components have an opening for the trunk to pass through to limit the swing of the top. A cutting mechanism, connected to the lower end of the clamping and limiting mechanism, includes a height-adjustable cutting assembly, the cutting assembly having a rotatable cutting blade with an outwardly expanding cutting edge; The shifting mechanism, the lifting mechanism, the clamping and limiting mechanism, and the cutting mechanism are configured to work together to perform an integrated "alignment-clamping-pulling-cutting" operation.

[0007] Furthermore, the shifting mechanism includes a shifting motor, a gear transmission pair driven by the shifting motor, and a rotating shaft connected to the gear transmission pair. The rotating shaft is configured to drive the lifting mechanism to rotate at least 10 degrees in the horizontal plane so that the clamping and limiting mechanism can cover the front and rear sides of the base frame.

[0008] Furthermore, the limiting component of the clamping and limiting mechanism includes a pair of limiting arc plates arranged opposite each other. The limiting arc plates are located above the clamping component and there is a preset vertical distance between them to form a double-point support constraint on the tree trunk and prevent eccentric force during pulling.

[0009] Furthermore, the buffer support assembly of the lifting mechanism includes a slide cylinder, a slide rod, and a damping unit. The damping unit includes an anti-slip ring sleeved on the slide rod and a first compression spring located at the bottom of the inner cavity of the slide cylinder. The anti-slip ring is configured to generate a frictional force that hinders the movement of the slide rod when the telescopic rod retracts.

[0010] Furthermore, a limiting groove is provided on the slide rod, and a limiting member is provided on the slide cylinder to cooperate with the limiting groove. The limiting member is configured to limit the maximum extension stroke of the slide rod to prevent the components from detaching.

[0011] Furthermore, the cutting mechanism has an arc-shaped cutting edge, the end of which extends outward along the rotation direction to form a hook-like structure for gathering lateral roots, and the cutting mechanism achieves height adjustment through a multi-hole connection between the adjustment frame and the fixed plate.

[0012] Furthermore, the clamping assembly includes a bidirectional cylinder and a pair of grippers connected to the output end of the bidirectional cylinder. The grippers have arc-shaped clamping arms adapted to the shape of the tree trunk, and the clamping assembly is configured as two sets arranged at vertical intervals.

[0013] The present invention also provides a method for transplanting garden trees, which is implemented using the aforementioned transplanting device and includes the following steps: S1, Global Positioning: The base frame is moved by the traction equipment, and the clamping and limiting mechanism is aligned with the tree by the rotation function of the shifting mechanism; S2, Limiting clamping: The lifting mechanism descends, allowing the tree trunk to pass through the opening of the limiting component and enter the clamping range of the clamping component, thus completing the double-point fixation; S3, Damped Pull-out: The telescopic rod extends, causing the tree to move upward, and the parallel buffer support components provide bending moment support and downward buffer; S4, Dynamic root cutting: Adjust the cutting mechanism to the height of the root ball, and use the rotating and gathering action of the cutter to cut off the remaining roots; S5, Rotary Unloading: The shifting mechanism rotates in the opposite direction to transfer the tree to the target planting location.

[0014] Furthermore, in step S3, the anti-slip ring of the buffer support assembly generates frictional damping with the inner wall of the slide cylinder, which counteracts the inertial impact when the lifting mechanism descends.

[0015] Furthermore, in step S4, the hook-shaped structure of the cutter first gathers the lateral roots toward the center, and then cuts them off through the cutting edge.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The shifting mechanism is driven by a motor to rotate the shaft, which enables the lifting mechanism and the clamping and limiting mechanism and cutting mechanism linked with it to rotate in the horizontal direction. This allows the operation of trees on the front or back of the base frame without frequent movement of the whole machine, adapting to the transplanting needs of different locations.

[0017] 2. The lifting mechanism is equipped with a buffer support assembly, with a first compression spring and a rubber anti-slip ring between the slide rod and the slide cylinder. When the lifting cylinder retracts (descends), the friction between the anti-slip ring and the inner cavity, along with the compression force of the spring, provides damping, slowing down the descent speed, preventing the clamping mechanism and the tree from suddenly falling, and significantly improving operational stability.

[0018] 3. The clamping and limiting mechanism includes a clamping component and a limiting component that move synchronously vertically. The clamping component uses two sets of arc-shaped jaws to clamp the two ends of the tree; the limiting component has an opening design that allows the upper end of the tree to enter a pair of limiting arc plates, providing support and limiting, preventing the tree from tilting due to the weight of the lower end, and ensuring accurate and reliable clamping position.

[0019] 4. The cutting mechanism has an arc-shaped cutting edge that extends outward. When rotating to cut, it can actively gather the lateral roots around the tree, reduce root residue, cut more thoroughly, and improve the survival rate after transplanting.

[0020] 5. The cutting motor is mounted on the adjustment frame. The adjustment frame and the fixed plate are connected by bolts through multiple sets of mounting holes at different heights, which can quickly adjust the vertical position of the cutter to adapt to the root ball size or cutting depth requirements of different trees.

[0021] 6. The cutting mechanism is connected to the mounting frame of the clamping and limiting mechanism by screws through the fixed plate, and the adjusting frame is also connected to the fixed plate by bolts, which makes disassembly and assembly convenient and facilitates maintenance and replacement of parts.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] refer to Figures 1 to 22 ,like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a tree transplanting device for gardens, mainly composed of: a base frame 1, a shifting mechanism 2, a lifting mechanism 3, a clamping and limiting mechanism 4, and a cutting mechanism 5. The base frame 1 is towed by a tractor or other traction equipment to increase the convenience of movement. The shifting mechanism 2 is mounted on the base frame 1, and the lifting mechanism 3 is mounted on the shifting mechanism 2. The shifting mechanism 2 drives the lifting mechanism 3 to rotate horizontally. The lifting mechanism 3 acts as an actuator to clamp and pull up the tree. The lifting mechanism 3 includes a mounting base 31, a lifting cylinder 32, and a buffer support assembly 33. The lower ends of the lifting cylinder 32 and the buffer support assembly 33 are pivotally connected to the mounting base 31. The shifting mechanism 2 can drive the mounting base 31 to rotate, thereby causing the lifting cylinder 32 and the buffer support assembly 33 to rotate horizontally. The output end of the lifting cylinder 32 has a telescopic rod. 321. The upper end of the buffer support assembly 33 is pivotally connected to the telescopic rod 321. The buffer support assembly 33 is used to assist in supporting the telescopic rod 321 and provide damping to slow down the retraction speed of the telescopic rod 321 and increase the stability of the lifting cylinder 32. The clamping and limiting mechanism 4 is connected to the front end of the telescopic rod 321. It includes a clamping assembly 41 and a limiting assembly 42 that are arranged vertically and move synchronously. The clamping assembly 41 is used to clamp and hold the tree to be transplanted. The limiting assembly 42 can restrict the tree in the internal space so that the tree remains stable when the clamping assembly 41 clamps it. The cutting mechanism 5 is installed at the lower end of the clamping and limiting mechanism 4. The cutting mechanism 5 includes a rotatable cutter 54 with an outwardly expanding blade. The roots of the tree are cut by rotating the cutter 54. The height of the cutting mechanism 5 relative to the clamping and limiting mechanism 4 can be adjusted to adapt to different cutting needs. The shifting mechanism 2 drives the lifting mechanism 3 to rotate in the horizontal direction, which enables the clamping and limiting mechanism 4 and the cutting mechanism 5, which are linked to the lifting mechanism 3, to rotate synchronously. This allows the cutting mechanism 5 to be moved to the front or rear side of the base frame 1, so that the trees on both the front and rear sides of the base frame 1 can be operated.

[0047] The shifting mechanism 2 mainly consists of a shifting motor 21, a driving wheel 22, a driven wheel 23, a rotating shaft 24, and a protective box 25. The shifting motor 21 is installed in the mounting cavity 11 of the base frame 1. The driving wheel 22 and the driven wheel 23 form a gear transmission pair. The driving wheel 22 is connected to the output end of the shifting motor 21. The driven wheel 23 and the driving wheel 22 are both gears, and they mesh to achieve power transmission. The rotating shaft 24 is connected in the driven wheel 23. The upper end of the rotating shaft 24 passes through the mounting cavity 11 and the protective box 25 and is connected to the mounting base 31. The protective box 25 protects the rotating shaft 24. Driven by the shifting motor 21 and the gear transmission pair, the rotating shaft 24 can drive the lifting mechanism 3 to rotate at least 180 degrees in the horizontal plane so that the clamping and limiting mechanism 4 can cover the front and rear sides of the base frame 1.

[0048] like Figure 10 , Figure 11As shown, the bottom of the lifting cylinder 32 is pivotally connected to the pivot seat 336, which is fixedly connected to the mounting base 31. The top of the lifting cylinder 32 is connected to the telescopic rod 321. A pair of connecting seats 35 are fixedly installed at the lower end of the connecting plate 34, and the threaded section of the telescopic rod 321 is threadedly connected to the threaded hole of the corresponding connecting seat 35. A pair of guide posts 36 are fixed on the mounting base 31, and the guide posts 36 slide in engagement with the lugs 341 on the connecting plate 34. By setting the lugs 341 to slide with the guide posts 36, the stability of the movement of the connecting plate 34 is improved.

[0049] like Figure 6 and Figure 10 As shown, the buffer support assembly 33 mainly consists of a slide cylinder 331, a slide rod 332, and a damping unit including a first compression spring 333 and an anti-slip ring 334. The bottom of the slide cylinder 331 is connected to the mounting base 31 through a pivot seat 336. The slide rod 332 is slidably engaged with the inner cavity 3311 of the slide cylinder 331. The threaded section at the upper end of the slide rod 332 is threadedly connected to the threaded hole of the corresponding connecting seat 35. The first compression spring 333 is connected between the bottom of the slide rod 332 and the inner cavity 3311. The anti-slip ring 334 is sleeved on the slide rod 332 and abuts against the inner cavity 3311. When the telescopic rod 321 retracts, the anti-slip ring 334 generates friction to resist the movement of the slide rod 332.

[0050] like Figure 12 As shown, a limiting groove 3321 is formed axially on one side of the slide rod 332, and a locking hole 3312 is formed on the side of the slide cylinder 331. A limiting member 335 is threadedly connected to the locking hole 3312, and the front end of the limiting member 335 extends into the limiting groove 3321. The limiting member 335 is installed after the slide rod 332 is connected to the slide cylinder 331 to limit the maximum extension stroke of the slide rod 332. When the lower end of the slide rod 332 slides to the limiting groove 3321 and contacts the limiting member 335, the limiting member 335 can act as a block, thereby preventing the slide rod 332 from disengaging from the inner cavity 3311. During disassembly, the limiting member 335 is removed, which allows the slide rod 332 to disengage from the slide cylinder 331.

[0051] Preferably, such as Figure 13 As shown, the limiting member 335 is preferably a screw.

[0052] like Figure 14As shown, the number of anti-slip rings 334 is selected according to the required frictional damping force, either one or two, made of rubber, and located below the limiting groove 3321. Specifically, the lower end of the slide rod 332 has a mounting groove 3322, and the anti-slip ring 334 is fitted into the mounting groove 3322. By setting the anti-slip ring 334 on the slide rod 332, when the slide rod 332 slides against the inner cavity 3311, the anti-slip ring 334 and the inner cavity 3311 generate friction, which has the effect of hindering the sliding of the slide rod 332. Therefore, when the lifting cylinder 32 retracts, the friction generated by the slide rod 332 against the slide cylinder 331 can hinder the downward movement of the clamping limiting mechanism 4 and the cutting mechanism 5, thereby making the downward repositioning of the clamping limiting mechanism 4 and the cutting mechanism 5 more stable. In addition, when the slide rod 332 slides down to the lower end of the inner cavity 3311, the slide rod 332 will squeeze the first compression spring 333, further increasing the buffering effect.

[0053] Example 2, like Figure 15 As shown, The lower end of the slide rod 332 is provided with a positioning shaft 6, and an anti-slip ring 334 is fitted into the mounting groove 3322. A pressure cap 61 is fitted onto the positioning shaft 6, and the inner hole of the pressure cap 61 is in sliding engagement with the positioning shaft 6. The upper end face of the pressure cap 61 presses against the lower end face of the slide rod 332, and the lower end face of the pressure cap 61 presses against the upper end of the first compression spring 333. The outer circle of the pressure cap 61 is in sliding engagement with the inner wall of the slide cylinder 331, and the edge of the upper end face of the pressure cap 61 is constructed as the lower wall of the mounting groove 3322. When installing the anti-slip ring 334, the anti-slip ring 334 is first fitted onto the outer periphery formed by the inner bottom wall of the mounting groove 3322, and then the pressure cap 61 is fitted onto the positioning shaft 6. The pressure cap 61 is fixed to the positioning shaft 6 using hexagon socket screws, thereby the edge of the upper end face of the pressure cap 61 presses against the lower end face of the anti-slip ring 334. This structure facilitates the installation and removal of the anti-slip ring 334. Compared to embodiment 1, the installation and removal of the anti-slip ring 334 is more convenient, and damage to the anti-slip ring 334 is avoided during installation.

[0054] like Figure 16 As shown, the anti-slip ring 334 has an inner ring 3341 and multiple annular wear-resistant protrusions 3342 integrally connected to the outer periphery of the inner ring 3341. The inner ring 3341 is fitted into the mounting groove 3322, and the multiple annular wear-resistant protrusions 3342 abut against the inner wall of the slide cylinder 331. The arrangement of multiple annular wear-resistant protrusions 3342 improves the friction.

[0055] Example 3, like Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21As shown, the anti-slip ring 334 is further improved. The anti-slip ring 334 has an inner ring 3341, which is fixed to the mounting groove 3322 by a hexagonal socket screw. The head of the hexagonal socket screw presses against a washer 62, and the washer 62 presses against the outer circumference of the inner ring 3341. Several connecting bodies 3343 are provided on the upper end of the inner ring 3341, which is inclined outwards. The inner and outer walls of the connecting bodies 3343 are arc-shaped. A limiting block 3344 is connected to the connecting body 3343. Multiple second compression springs 63 are provided between the inner wall of the limiting block 3344 and the inner bottom wall of the mounting groove 3322. There is a 2mm to 3mm gap between the upper end face of the limiting block 3344 and the upper wall of the mounting groove 3322 to prevent the limiting block 3344 from jamming during operation.

[0056] The outer wall of the limiting block 3344 is provided with a plurality of protrusions 3345, which abut against the side wall of the inner cavity 3311.

[0057] Preferably, the anti-slip ring 334 also has a plurality of notches 3346, which are located between two adjacent limiting blocks 3344.

[0058] like Figure 22 As shown, one end face of the washer 62 has an arc-shaped surface 621 that fits against the outer periphery of the inner ring 3341, making the connection between the hexagon socket screw and the mounting groove 3322 more secure.

[0059] like Figure 7 As shown, both the clamping assembly 41 and the limiting assembly 42 are mounted on the mounting frame 43, which is fixedly connected to the end of the connecting plate 34, and the clamping assembly 41 is located below the limiting assembly 42. The clamping assembly 41 includes a bidirectional cylinder 411 and a pair of grippers 412 connected to both ends of the bidirectional cylinder 411. The bidirectional cylinder 411 can control the synchronous relative movement of the pair of grippers 412. When the pair of grippers 412 approach each other synchronously, the tree can be clamped. The grippers 412 have arc-shaped clamping arms 4121. Setting the clamping arms 4121 to be arc-shaped can better match the cylindrical shape of the tree, thus making the clamping more reliable.

[0060] The clamping components 41 are provided in two sets, and the two sets are distributed at intervals, which can clamp the two sections of the tree, thus making the clamping more secure and stable.

[0061] like Figure 8As shown, the limiting component 42 mainly consists of: a mounting frame 421, a limiting frame 422, and a pair of oppositely arranged limiting arc plates 423. The mounting frame 421 is mounted on the mounting frame 43, the limiting frame 422 is connected to the mounting frame 421, and the pair of limiting arc plates 423 are connected oppositely to the lower end of the limiting frame 422 in the front-back direction. The pair of limiting arc plates 423 are located above the clamping component 41, and there is a preset vertical distance between them to form a double-point support constraint on the tree trunk and prevent eccentric force during pulling.

[0062] Preferably, the end of the limiting frame 422 away from the mounting frame 421 has an extension 4221 that is close to each other. There are openings 4222 between the pair of extensions 4221 and between the pair of limiting arc plates 423 to allow the tree to enter. When the clamping assembly 41 gradually approaches and clamps the tree, the upper part of the tree located at the clamping part enters the limiting assembly 42 through the two openings 4222. The limiting assembly 42 can support and limit the tree, reduce the tilting and displacement of the upper part of the tree caused by the heavier weight at the lower end, so that the clamping position of the clamping assembly 41 is more accurate and reliable.

[0063] The cutting mechanism 5 mainly consists of a cutting motor 52, a mounting plate 53, several cutting blades 54 and a fixing plate 55. The fixing plate 55 has fixing holes 551. By passing screws through the fixing holes 551, it is threaded to the mounting frame 43, so that the fixing plate 55 can be fixed on the mounting frame 43, thereby realizing the quick installation between the cutting mechanism 5 and the clamping and limiting mechanism 4.

[0064] The cutting motor 52 is mounted on the adjusting frame 51, and the mounting plate 53 is connected to the lower end of the cutting motor 52. Several cutters 54 are mounted in a ring around the mounting plate 53. The fixing plate 55 is fixed on the clamping and limiting mechanism 4. The adjusting frame 51 is connected to the fixing plate 55, and the height of the adjusting frame 51 on the fixing plate 55 can be adjusted, thereby realizing the change of the cutting height of the cutter 54.

[0065] like Figure 9 As shown, the cutter 54 has a cutting edge 541, which is arc-shaped and extends outward along the rotation direction to form a hook-like structure for gathering lateral roots, thereby making the root cutting more thorough. The cutting mechanism 5 achieves height adjustment through the multi-hole connection between the adjusting bracket 51 and the fixed plate 55.

[0066] like Figure 4 and Figure 5As shown, the fixed plate 55 has several vertically arranged first mounting holes 552, and the adjusting frame 51 has second mounting holes 511 that can be matched with the first mounting holes 552. After the bolt passes through the second mounting hole 511 and the first mounting hole 552, it is locked by a nut. By moving the adjusting frame 51 up and down, the second mounting hole 511 can be matched with the first mounting holes 552 at different heights, so as to adjust the height of the adjusting frame 51 and thus achieve the purpose of adjusting the cutting height of the cutter 54.

[0067] This embodiment also provides a method for transplanting garden trees, which uses a transplanting device for transplanting, and specifically includes the following steps: Step S1, Global Positioning: Move the base frame 1 using the traction device, and use the rotation function of the shifting mechanism 2 to align the clamping and limiting mechanism 4 with the tree; S2, Limiting clamping: The lifting mechanism 3 descends, allowing the tree trunk to pass through the opening 4222 of the limiting component 42 and enter the clamping range of the clamping component 41, completing the double-point fixation; S3, Damped Pull-out: The telescopic rod 321 extends, causing the tree to move upward, and the parallel buffer support assembly 33 provides bending moment support and downward buffer; S4, Dynamic root cutting: Adjust the cutting mechanism 5 to the height of the root ball, and use the rotating and gathering action of the cutter 54 to cut off the remaining roots; S5, Rotary unloading: The shifting mechanism 2 rotates in the opposite direction to transfer the tree to the target planting position.
