Description

Technical Field

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

[0002] A garden refers to a specially cultivated natural environment and recreational area. A beautiful natural environment and recreational area created within a specific region using engineering techniques and artistic methods, through modifying the terrain (or further constructing mountains, stacking rocks, and managing water), planting trees and flowers, constructing buildings, and arranging garden paths, is called a garden. Gardens require the planting of a large number of trees to beautify them and enhance their aesthetic appeal. During the transplanting process, transplanting equipment is needed to move the trees.

[0003] Regarding the aforementioned technologies, current transplanting equipment typically uses three wedges to hold the tree trunk in place. Due to the sliding connection between the extrusion plate and the second limiting groove, and the inclined structure of the inner side wall of the first locking plate, the extrusion plate moves horizontally when it slides up and down, thereby achieving horizontal displacement of the three bonding plates to lock the shrub trunk in the inner cavity of the first locking plate, thus achieving fixed positioning of the tree trunk.

[0004] However, in actual use, the vertical pole is often stuck near the root. In strong winds, the tree may sway, and although the wedges hold the trunk in place, the violent swaying of the tree may cause the upper part of the trunk to break. Therefore, a transplanting method for landscaping construction is proposed. Summary of the Invention

[0005] To address the above problems, this invention provides a transplanting method for landscaping construction, employing the following technical solution:

[0006] A transplanting method for landscaping construction includes the following steps:

[0007] S1. Preparation steps: First, wrap the transplanting device around the tree to be moved, then support and fix the transplanting device with the support structure, and insert the transplanting device into the ground for fixation and support.

[0008] S2. Fixing Step: When the transplanting device is attached to the tree, the clamping structure on the transplanting device clamps against the trunk to reduce the problem of the trunk tipping over and ensure that the transplanted tree can grow normally.

[0009] S3. Protection Steps: In windy conditions, when trees sway, the clamping structure is squeezed and the buffer structure is compressed to cushion the impact and reduce the chance of trunk breakage. During the buffering process, the reinforcing structure is driven to increase the support and stability of the transplanting device. At the same time, the first and second protective structures are moved upward as a whole to increase the protection range on the trunk and improve the protection effect.

[0010] The transplanting device in step S1 includes a first fastening frame in the shape of a semi-circular ring. A second fastening frame is rotatably connected to one end of the first fastening frame. Arc-shaped fixing strips are installed on the outer surfaces of both the first and second fastening frames.

[0013] Furthermore, the buffer structure includes a vertical rod connected between the inner walls of the upper and lower ends of the fixed frame. The vertical rod moves through a through hole opened on the buffer block. Springs are sleeved at both the upper and lower ends of the vertical rod. The two ends of the springs are respectively connected to the inner wall of one end of the buffer block and the fixed frame. A first crank is rotatably connected to the inner side of each buffer block. One end of each set of two first cranks is rotatably connected to the corresponding mounting base.

[0014] Furthermore, the second protective structure includes a second lifting bar disposed on the top of the first top block. The second lifting bar is movably inserted into a hole opened in the first top block and the first lifting bar. The top of the second lifting bar is connected to the second top block. A second fixing rod is connected to the middle of the upper part of the second top block. A second protective plate is installed on one end of the second fixing rod. The first top block is provided with a lifting structure.

[0015] Furthermore, the lifting structure includes a first through groove opened on both sides inside the first top block, a guide groove opened on the upper groove wall of the first through groove, a moving block slidably arranged in the first through groove and the guide groove, a second crank rod rotatably connected to the top of the moving block, the top of the second crank rod being connected to the second top block, and a transmission structure provided between the moving block and the fixed block.

[0016] Furthermore, the transmission structure includes a U-shaped frame mounted on a fixed block.

[0036] The following is combined with Figure 1-7 The present invention will be described in further detail below.

[0037] Please see Figure 1-7 A transplanting method for landscaping construction includes the following steps:

[0038] S1. Preparation steps: First, wrap the transplanting device around the tree to be moved, then support and fix the transplanting device with the support structure, and insert the transplanting device into the ground for fixation and support.

[0039] S2. Fixing Step: When the transplanting device is attached to the tree, the clamping structure on the transplanting device clamps against the trunk to reduce the problem of the trunk tipping over and ensure that the transplanted tree can grow normally.

[0040] S3. Protection Steps: In windy conditions, when trees sway, the clamping structure is squeezed and the buffer structure is compressed to cushion the impact and reduce the chance of trunk breakage. During the buffering process, the reinforcing structure is driven to increase the support and stability of the transplanting device. At the same time, the first and second protective structures are moved upward as a whole to increase the protection range on the trunk and improve the protection effect.

[0041] The transplanting device in step S1 includes a first fastening frame 1 in the shape of a semi-circular ring. A second fastening frame 12 is rotatably connected to one end of the first fastening frame 1. Arc-shaped fixing strips 4 are installed on the outer surfaces of both the first fastening frame 1 and the second fastening frame 12. A locking structure is provided between the first fastening frame 1 and the second fastening frame 12. A bottom frame 2 is provided directly below the first fastening frame 1 and the second fastening frame 12. A support structure is installed on the bottom frame 2. Connecting posts 3 are connected to both ends of each bottom frame 2. The tops of the two sets of connecting posts 3 are respectively connected to the first fastening frame 1 and the second fastening frame 12. Multiple fixing frames 5 are connected to the top of each bottom frame 2. Two buffer blocks 6 are slidably arranged inside each fixing frame 5. A first protective structure is installed on the upper buffer block 6. Each clamping structure is set on the two buffer blocks 6 in each set through the buffer structure. A reinforcing structure is set on the lower buffer block 6.

[0042] The first protective structure includes a first lifting bar 7 connected to the outer side of each upper buffer block 6. The first lifting bar 7 is L-shaped. A fixing block 11 is movably sleeved on the first lifting bar 7 near the bottom end. The fixing block 11 is connected to the side of the fixing bar 4. A first top block 8 is connected to the top of the first lifting bar 7. The second protective structure is set on the first top block 8. A first fixing rod 9 is connected to the middle of the inner side of the first top block 8. A first protective plate 10 is installed on one end of the first fixing rod 9. The first protective plate 10 is an arc-shaped plate.

[0043] The clamping structure includes a clamping plate 28 disposed in the inner groove of each fixed frame 5. The clamping plate 28 is an arc-shaped plate, and a mounting base 16 is installed on the clamping plate 28. The buffer structure is disposed on the clamping plate 28 and the fixed frame 5. The buffer structure includes a vertical rod 13 connected between the inner walls of the upper and lower ends of the fixed frame 5. The vertical rod 13 movably passes through a through hole opened in the buffer block 6. Springs 14 are sleeved at both the upper and lower ends of the vertical rod 13. The two ends of the springs 14 are respectively connected to the inner wall of one end of the buffer block 6 and the fixed frame 5. Each buffer block 6 has a rotatable connection on its inner side. There is a first crank rod 15, and one end of each set of two first crank rods 15 is rotatably connected to the corresponding mounting base 16. The locking structure includes an arc-shaped groove 32 opened on one end face of the second fastening frame 12. Second through grooves 33 are opened on both the upper and lower sides of the arc-shaped groove 32. An insert plate 34 is slidably arranged in the arc-shaped groove 32. One end of the insert plate 34 is movably inserted into the locking groove 36 opened on the end face of the first fastening frame 1. A bolt 37 is installed on the first fastening frame 1. The bottom end of the bolt 37 is tightened into the locking hole opened on the insert plate 34. The other end of the insert plate 34... A limiting block 35 is installed on the end, and the limiting block 35 is inserted into the second through groove 33. When transplanting trees, firstly, the opened first fastening frame 1 and second fastening frame 12 are placed on the outside of the transplanted tree, and the first fastening frame 1 and second fastening frame 12 are closed, which drives multiple clamping plates 28 to press against the lower part of the trunk. Then, the limiting block 35 pushes one end of the insert plate 34 on the second fastening frame 12 into the locking groove 36 of the first fastening frame 1. The first fastening frame 1 and the second fastening frame 12 are fixed together by bolts 37, and then... The transplanting device is inserted into the ground for support through the support structure. In strong winds, the swaying of the tree compresses the corresponding clamping plate 28, pushing the two buffer blocks 6 in each group to move away from each other on the vertical rod 13. This causes the spring 14 to compress, and the elastic force generated by the spring 14 is used to cushion the tree. Furthermore, the upward movement of the upper buffer block 6 causes the first lifting bar 7 and the first protective plate 10 to move upward as a whole, increasing the protection range on the tree trunk and reducing the possibility of the upper part of the tree trunk breaking under violent shaking.

[0044] The second protective structure includes a second lifting bar 17 disposed on the top of the first top block 8. The second lifting bar 17 is movably inserted into the insertion holes opened in the first top block 8 and the first lifting bar 7. The top of the second lifting bar 17 is connected to a second top block 18. A second fixing rod 19 is connected to the middle of the upper part of the second top block 18. A second protective plate 20 is installed on one end of the second fixing rod 19. A lifting structure is provided on the first top block 8. The lifting structure includes a first through groove 21 opened on both sides inside the first top block 8. A guide groove 24 is opened on the upper groove wall of the first through groove 21. A moving block 22 is slidably disposed in the first through groove 21 and the guide groove 24. A second crank 23 is rotatably connected to the top of the moving block 22. The top of the second crank 23 is connected to the second top block 18. A transmission structure is provided between the moving block 22 and the fixing block 11. The transmission structure includes an installation A U-shaped frame 27 on the fixed block 11 has a through hole in the middle of its upper part for the first lifting bar 7 to pass through. Guide grooves 26 are provided on both sides of the outer side of the U-shaped frame 27. The lower part of the guide groove 26 is "S" shaped. Each movable block 22 is connected to an insertion rod 25 that passes through the first through groove 21. The insertion rod 25 is "L" shaped, and one end of the insertion rod 25 is movably inserted into the guide groove 26. As the first lifting bar 7 moves upward, it drives one end of the insertion rod 25 to slide upward in the guide groove 26 of the U-shaped frame 27, thereby driving the two movable blocks 22 in the first top block 8 to move synchronously towards each other. Through the second curved rod 23, the second top block 18 and the second lifting bar 17 are pushed together on the first top block 8 to drive the second protective plate 20 to move upward, further expanding the protection range on the tree trunk and improving the protection effect.

[0045] The support structure includes multiple plug-in posts 29 connected to the side of the base frame 2. The plug-in posts 29 are L-shaped, and plug-in blocks 30 are installed at the bottom of the plug-in posts 29. The plug-in blocks 30 are conical in shape. The reinforcement structure includes a reinforcement rod 31 connected to each lower buffer block 6. The reinforcement rod 31 moves through the through hole opened in the plug-in post 29. The bottom end of the reinforcement rod 31 is pointed. The plug-in block 30 at the bottom end of the plug-in post 29 is inserted into the ground to support the transplanting device on the ground. As the lower buffer block 6 moves downward, it drives the reinforcement rod 31 to move down and insert into the ground. In windy conditions, this increases the stability of the transplanting device and reduces the risk of tipping over.

[0046] The implementation principle of this invention is as follows: During use, the worker first places the opened first fastening frame 1 and the second fastening frame 12 around the transplanted tree and closes the first fastening frame 1 and the second fastening frame 12. Then, using the limiting block 35, one end of the insert plate 34 in the second fastening frame 12 is inserted into the locking groove 36 on the end face of the first fastening frame 1. The insert plate 34 is fixed in the first fastening frame 1 by bolts 37. The locking between the first fastening frame 1 and the second fastening frame 12 will cause multiple clamping plates 28 to press against the lower part of the tree trunk. Next, the inserting block 30 at the bottom of the inserting post 29 is inserted into the ground to fix and support the transplanting device. In a strong wind environment, the violent shaking of the tree will cause the clamping plates 28 to move. The first curved rod 15 pushes the two buffer blocks 6 of each group to move away from each other on the corresponding vertical rod 13. The upper buffer block 6 causes the spring 14 to compress, which... The spring force generated by spring 14 acts as a buffer for the tree. The upper buffer block 6 drives the first lifting bar 7 and the first protective plate 10 to move upward as a whole, increasing the protection range on the tree trunk and reducing the possibility of the upper part of the tree trunk breaking under violent shaking. At the same time, as the first lifting bar 7 moves upward, it drives one end of the insertion rod 25 to slide upward in the guide groove 26 of the U-shaped frame 27, thereby driving the two moving blocks 22 in the first top block 8 to move synchronously towards each other. Through the second curved rod 23, it pushes the second top block 18 and the second lifting bar 17 together on the first top block 8 to drive the second protective plate 20 to move upward, further expanding the protection range on the tree trunk and improving the protection effect. When the lower buffer block 6 moves downward, it drives the reinforcing rod 31 to move downward and insert into the ground. In windy conditions, it increases the support and stability of the transplanting device, reduces the problem of tipping over, and thus improves the transplanting quality.

[0047] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
