Description

Technical Field

[0001] This invention relates to the field of pruning device technology, and in particular to a high-branch pruning device for municipal landscaping. Background Technology

[0002] The primary purpose of pruning tall branches of trees in municipal landscaping is to ensure public safety and tree health, while also enhancing the urban landscape and ecological functions. Pruning overly dense, dead, or unsafe branches effectively prevents trees from falling or branches from breaking, protecting pedestrians, vehicles, and surrounding facilities. It also improves ventilation and light penetration, reduces pests and diseases, and promotes healthy growth. Furthermore, proper pruning helps create aesthetically pleasing tree shapes, enhances the overall streetscape, and harmonizes the relationship between trees and urban infrastructure, lighting, and buildings, achieving harmonious coexistence between people and the natural environment. However, specialized pruning equipment is required for pruning tall branches in municipal landscaping.

[0003] In existing technologies, conventional equipment lacks a stable axis of rotation, making it difficult to perform circumferential pruning around the trunk with equal radius. This often results in uneven crown contours after pruning, leading to poor aesthetics and consistency. Furthermore, operators are typically positioned directly below or to the side of the pruning point, making them vulnerable to injury from falling branches and leaves. Additionally, securing the equipment or climbing often requires rigidly clamping or nailing the trunk, which can damage the bark and cambium, impacting tree health. Moreover, adjusting pruning height and angle relies heavily on frequent manual interruptions to reposition the equipment or climb ladders, resulting in an uncoordinated process. It is particularly difficult to achieve automated, uniform, spiraling upward pruning, leading to omissions and overall low operational efficiency. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this invention is to provide a high-branch pruning device for municipal landscaping.

Subsequently, by simply holding the control component, the entire transmission component and pruning mechanism can be directly driven to rotate around the tree trunk, and the high branches of the tree can be pruned in the process. Therefore, by using the tree trunk as the center, the length of the pruning can be ensured to be more even and uniform.

[0017] 2. During pruning, this high-branch pruning device for municipal landscaping uses a docking mechanism to position the pruning area and the manual control area of ​​the entire device on opposite sides of the tree. This structure ensures that falling branches and leaves will not fall on the workers, improving the safety of the entire pruning project. The device does not require excessive clamping of the tree trunk during the operation, reducing damage to the trunk area. With the help of the baffle, during breaks, the handle can be released and the baffle can be placed against the surface of the tree trunk to ensure that the entire device can maintain its current posture and will not tip over even without manual support.

[0018] 3. This high-branch pruning device for municipal landscaping utilizes a transmission component that, during pruning, automatically controls the top pruning mechanism to slowly rise in sync as the transmission component rotates around the tree trunk. This eliminates the need for frequent adjustments to the pruning process, achieving a spiral upward effect on the pruning area while rotating around the tree, further improving pruning efficiency. Simultaneously, it can work with the bottom support component to actively adjust the height of the pruning mechanism, achieving proactive fine-tuning to ensure no branches are missed.

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] like Figures 1 to 7 As shown in the figure, this embodiment of the invention proposes a high-branch pruning device for municipal landscaping. The pruning device includes: a transmission component 1 and a pruning mechanism 2. The bottom of the transmission component 1 is fitted with a movable wheel 25, the bottom of which is used to press against the ground. The top of the transmission component 1 is fitted with the pruning mechanism 2. The pruning mechanism 2 includes a lifting rod 20, a motor 21, and a saw blade 22. The bottom of the lifting rod 20 is embedded in the inner side of the transmission component 1. The top of the lifting rod 20 is screwed with the motor 21. The output shaft of the motor 21 is screwed with the saw blade 22, which is used to prune high branches of trees. The pruning device also includes a docking mechanism 3, a control component 4, and a support component 5. The docking mechanism 3 is partially connected to the transmission component 1. The control component 4 is installed on the side of the docking mechanism 3. A support rod 10 is screwed to the bottom of the docking mechanism 3. A second ball bearing 11 is embedded at the bottom end of the support rod 10. The support component 5 is installed at the bottom of the tree to be pruned. The docking mechanism 3 presses against the surface of the support component 5 through the support rod 10 at the bottom and the second ball bearing 11. The docking mechanism 3 is used to drive the transmission component 1 and the pruning mechanism 2 to rotate around the tree.

[0023] This municipal landscaping high-branch pruning device is used to prune the high branches of trees in landscaping. When in use, first, the bottom support component 5 is placed around the bottom of the tree trunk, and then the docking mechanism 3 is placed on the side of the tree trunk. The bottom support rod 10 and the second ball bearing 11 are pressed against the surface of the support component 5. At this time, the moving wheel 25 at the bottom of the transmission mechanism is also pressed against the ground around the tree trunk. At this time, the entire device can be directly set up.

[0024] In subsequent use, starting the motor 21 at the top of the pruning mechanism 2 will control the saw blade 22 at the top to operate. At this time, manually pull the control component 4 to separate the two baffles 17, and manually control the entire docking mechanism 3 to rotate around the trunk. This will directly drive the docking mechanism 3, the transmission component 1, and the pruning mechanism 2 to rotate around the trunk. With the help of the saw blade 22 at the top, the purpose of pruning the branches can be achieved. During the operation of the entire device, the saw blade 22 at the top will also be automatically driven to rise slowly. At this time, the saw blade 22 will be automatically controlled to move upward gradually during the rotation of the pruning mechanism 2, thereby pruning the branches at different heights layer by layer.

[0025] In this embodiment, the docking mechanism 3 includes: The assembly includes a bonding plate 6, a first ball bearing 7, a receiving sleeve 8, and a locking bolt 9. The first ball bearing 7 is embedded in the inner wall of the bonding plate 6. The bonding plate 6 has an overall arc-shaped structure. The receiving sleeve 8 is welded to the rear end of the bonding plate 6. The locking bolt 9 is inserted into the surface of the receiving sleeve 8. There are two receiving sleeves 8, and the receiving sleeves 8 are used to dock and lock with the transmission assembly 1.

[0026] One side of the bonding plate 6 is open, and the bonding plate 6 is pressed against the surface of the tree trunk to be pruned by the first ball bearing 7. The top end of the support rod 10 and the bottom end of the bonding plate 6 are screwed together. There are two support rods 10 and two first ball bearings 7, and the two support rods 10 are kept parallel to each other.

[0027] The control component 4 includes: The bracket 12, fixed handle 13, spring rod 14 and slide groove 16 are provided. The fixed handle 13 is installed on the inner side of the end of the bracket 12. The slide groove 16 is provided on the inner wall of the bracket 12. The movable handle 15 is inserted into the slide groove 16. The spring rod 14 is inserted into the side of the movable handle 15. The other end of the spring rod 14 is welded to the surface of the fixed handle 13. The fixed grip 13 and the movable grip 15 are kept in a parallel state, and both ends of the movable grip 15 slide along the inside of the slide groove 16. The rod inside the spring rod 14 passes through the inside of the movable grip 15. The bracket 12 and the bonding plate 6 are integrally formed.

[0028] The control component 4 also includes: The baffle 17 and the buffer pad 18 are attached to the surface of the baffle 17 and are made entirely of rubber. The top and bottom of the buffer pad 18 and the baffle 17 are embedded in the groove 16. The side of the movable handle 15 is welded and fixed to the side of the baffle 17. The control component 4 is symmetrically arranged on both sides of the bonding plate 6. The two baffles 17 move along the corresponding grooves 16 and then dock with each other. After docking, the baffles 17 are used to abut against the surface of the tree trunk to be pruned.

[0029] During pruning, the docking mechanism 3 allows the pruning area and the manual control area of ​​the entire device to be located on opposite sides of the tree. This structure ensures that falling branches and leaves will not fall on the workers, improving the safety of the entire pruning process. The entire operation does not require excessive clamping of the trunk, thus reducing the risk of damage to the trunk area.

[0030] Specifically, by pressing the first ball bearing 7 on the inner side of the bonding plate 6 against the surface of the tree trunk and manually operating the control component 4, the entire docking mechanism 3 and the control component 4 can be driven to rotate around the tree trunk. Since the receiving sleeve 8 at the rear end of the bonding plate 6 is connected to the transmission component 1 through the insertion rod 26, the insertion depth of the insertion rod 26 inside the receiving sleeve 8 can control the distance between the pruning mechanism 2 and the tree trunk, thereby selecting the specific pruning length and range. After the adjustment is completed, the locking bolt 9 can be turned to lock the receiving sleeve 8 and the insertion rod 26.

[0031] When a break is needed during pruning, simply release the movable handle 15. Under the action of the spring rod 14, the movable handle 15 and the baffle 17 will be pushed, and the baffle 17 will slide along the slide groove 16, eventually colliding and docking the two baffles 17. At this point, simply release the grip on the control component 4, and the bonding plate 6 and the docked two baffles 17 can be used to enclose the tree trunk, thus completely preventing the entire device from tipping over when the grip on the device is released.

[0032] In this embodiment, the support component 5 includes: The base 35, column 36, extension plate 40, and rotating seat 41 are provided. The base 35 is composed of two semi-circular metal parts. The extension plate 40 is integrally formed on the side of the base 35. The rotating seat 41 is screwed onto the surface of the extension plate 40. The bottom of the base 35 is used to press against the bottom side of the tree to be pruned, and the base 35 is fitted onto the root of the tree to be pruned.

[0033] The support component 5 also includes: The base consists of four columns 36, a support ring 37, and an annular groove 38. The bottom of the column 36 is inserted into the surface of the base 35. The top of the column 36 is welded with a support ring 37. The surface of the support ring 37 is provided with an annular groove 38. The support ring 37 is composed of two semi-circular metal parts. There are four columns 36, which are used to support the support ring 37. The bottom of the second ball bearing 11 is pressed against the inside of the annular groove 38, and the second ball bearing 11 rolls along the inside of the annular groove 38.

[0034] The support component 5 also includes: The top plate 39 and the pedal 42 are provided. The top plate 39 is generally semi-circular in structure. One end of the top plate 39 is sleeved on the top of the rotating seat 41 by a rod. The top of the rotating seat 41 is also connected to the pedal 42. The pedal 42 is used to tilt the top plate 39 upward. The top plate 39 is used to tilt one half of the support ring 37 upward. The surface of the pedal 42 is engraved with anti-slip texture. The surface of the top plate 39 has a circular hole. Two of the four pillars 36 pass through the circular hole on the surface of the top plate 39.

[0035] With the help of the transmission component 1, during the pruning process, as the transmission component 1 rotates around the tree trunk, the top pruning mechanism 2 is automatically controlled to achieve a synchronous and slow lifting process. This eliminates the need for frequent adjustments to the pruning process, and the spiral lifting effect of the pruning area can be achieved while rotating around the tree, further improving pruning efficiency. At the same time, it can also work with the bottom support component 5 to actively adjust the height of the pruning mechanism 2, thereby achieving the purpose of active height fine adjustment and ensuring that no branches are missed.

[0036] Specifically, the bottom of the docking mechanism 3 is pressed against the surface of the support ring 37 by the support rod 10 and the second ball bearing 11. Therefore, when the docking mechanism 3 is manually rotated, in addition to the moving wheel 25 on one side providing support for the entire device, the bottom support assembly 5, in conjunction with the support rod 10, can also provide additional support from below the bonding plate 6. The second ball bearing 11 rotates along the inside of the annular groove 38. After the docking mechanism 3 is first controlled to rotate the bottom support rod 10 and the second ball bearing 11 to the area of ​​the support ring 37 above the top plate 39, then... When the foot pedal 42 is stepped on, the rotating seat 41 will lift the top plate 39 upward, which in turn will lift the corresponding support ring 37 area upward. At this time, the transmission component 1 and the bottom moving wheel 25 can be lifted off the ground by means of this lifting effect. In this state, the top trimming mechanism 2 presses down by its own weight, moving the rack 32 downward. Therefore, the gear set structure inside the transmission box 24 can control the moving wheel 25 to rotate in the opposite direction. Thus, even if the transmission component 1 no longer rotates along the ground, the trimming mechanism 2 can still be controlled to move downward.

[0037] In this embodiment, the transmission assembly 1 includes: The lifting sleeve 19, transmission box 24, moving wheels 25, and plug rod 26 are provided. The transmission box 24 is screwed to the side of the lifting sleeve 19. The bottom of the transmission box 24 is equipped with moving wheels. The surface of the transmission box 24 is provided with plug rod 26. The plug rod 26 is used to be embedded into the interior of the receiving sleeve 8. The end of the locking bolt 9 is used to abut against the surface of the plug rod 26. The bottom of the lifting rod 20 is inserted into the interior of the lifting sleeve 19. The transmission assembly 1 further includes: The lifting rod 20 has a groove 23, a cavity 29, an air guide column 30, and a through hole 31. The side of the lifting rod 20 has a groove 23, and the inner side of the lifting rod 20 has a cavity 29. The bottom of the inner wall of the lifting sleeve 19 is provided with an air guide column 30, and the inner side of the air guide column 30 has a through hole 31. The top end of the air guide column 30 is inserted into the cavity 29 from the bottom of the lifting rod 20. The air in the cavity 29 is connected to the external space of the lifting sleeve 19 through the through hole 31.

[0038] The transmission assembly 1 further includes: The drive gear 27, toothed belt 28, rack 32, first driven gear 33 and second driven gear 34 are provided. The drive gear 27 is keyed to the axle of the moving wheel 25. The toothed belt 28 is sleeved on the surface of the drive gear 27. The other end of the toothed belt 28 is sleeved on the first driven gear 33. The second driven gear 34 is screwed to the side of the first driven gear 33. The rack 32 is provided in the groove 23 on the side of the lifting rod 20. The rack 32 is used to mesh with the second driven gear 34.

[0039] With the help of the bottom support component 5 and the docking mechanism 3, the entire device can be supported against the tree trunk to be pruned. Subsequently, by simply holding the control component 4, the entire transmission component 1 and the pruning mechanism 2 can be directly driven to rotate around the tree trunk, and the high branches of the tree can be pruned in the process. Therefore, by using the tree trunk as the center, the length of the pruning can be more even and uniform.

[0040] Specifically, after the transmission assembly 1 rotates around the tree by manual control, the bottom moving wheel 25 presses down on the ground. After the moving wheel 25 rotates, it drives the toothed belt 28 to rotate through the drive gear 27. The toothed belt 28 then drives the first driven gear 33 and the second driven gear 34 to rotate, ultimately pushing the rack 32 upward to achieve the purpose of slowly moving the pruning mechanism 2 upward. When the top pruning mechanism 2 is lowered in a fixed position by manually controlling it by stepping on the pedal 42, the air in the inner cavity 29 is discharged outward through the through hole 31 to limit the descent rate of the pruning mechanism 2.
