Description

Technical Field

[0001] This utility model relates to the field of plant pruning technology, specifically a palm tree branch and leaf pruning device. Background Technology

[0002] Palm trees are common ornamental and economic tree species in tropical and subtropical regions. With their upright trunks and spreading leaves, they are widely used in landscaping, street greening, and cash crop cultivation. As palm trees grow, the lower, older, and withered leaves gradually wither and turn yellow, affecting the overall aesthetic appeal of the plant. Furthermore, the withered branches and leaves are prone to falling off during windy and rainy weather, posing a safety hazard to pedestrians, vehicles, and surrounding facilities. Therefore, regular pruning of palm tree branches and leaves is an essential part of palm tree maintenance.

[0003] Traditional palm tree pruning relies heavily on manual labor using long-handled tools or ladders. This method is not only labor-intensive and inefficient, but also poses a significant risk of falls, as operators must work at heights when pruning the upper branches of tall palm trees. To address this issue, electric pruning tools are increasingly being used in palm tree pruning. Their powerful motors and relatively easy operation have improved pruning efficiency and safety to some extent.

[0004] However, existing palm tree pruning devices mostly have fixed connections between the cutting blades and the main structure, making quick disassembly impossible. After pruning, the exposed cutting blades are prone to collisions with people or surrounding objects during the carrying or transport of electric pruning tools, which can cause accidental injuries and increase the safety risks of tool storage and handling. In addition, palm tree fiber is tough, and the cutting blades are prone to wear and dulling after long-term use. Existing blades are cumbersome to disassemble and are inconvenient for operators to remove for grinding and repair.

[0005] To address this issue, we provide a palm tree branch and leaf pruning device. Utility Model Content

[0027] Please see Figures 1-3 In this embodiment of the utility model, the palm branch and leaf pruning device includes a cylindrical housing 1. A fixed side block 2 is fixedly connected to the upper end of the cylindrical housing 1. A shearing fixed blade 9 is provided on one side of the fixed side block 2. A fixed hole plate 10 is fixedly connected to the shearing fixed blade 9. A threaded post 12 is fixedly connected to one side of the fixed side block 2. The fixed hole plate 10 is provided with a clearance hole for avoiding the threaded post 12. A hand-tightening nut 14 for fixing the fixed hole plate 10 is provided on the threaded post 12. The fixed side block 2 is provided with a mounting hole for the fixed hole plate. The positioning component for positioning 10; the shearing fixed blade 9 cooperates with the fixed side block 2 through the fixed hole plate 10. During assembly, the clearance hole on the fixed hole plate 10 first avoids the threaded post 12 to ensure that the fixed hole plate 10 and the fixed side block 2 fit together. Then, the positioning component on the fixed side block 2 positions the fixed hole plate 10 to prevent skewing. Then, the hand-tightening nut 14 is screwed onto the threaded post 12 to lock the fixed hole plate 10, completing the assembly and making the shearing fixed blade 9 firmly fixed. When disassembly is required, the hand-tightening nut 14 can be unscrewed from the threaded post 12.

[0028] Please see Figure 3 The positioning component includes positioning pins 15, which are fixedly connected to the four corners of the fixed side block 2. The fixed hole plate 10 has positioning holes at the corresponding positions of the positioning pins 15, and the ends of the positioning pins 15 are all chamfered. During assembly, the positioning holes of the fixed hole plate 10 are aligned with the positioning pins 15, and the chamfers at the ends of the positioning pins 15 serve as guides to facilitate the insertion of the positioning pins 15 into the positioning holes. After the positioning pins 15 are inserted into the positioning holes, the fixed hole plate 10 is positioned to ensure the accuracy of the installation position of the shearing blade 9 and to avoid displacement.

[0029] Please see Figures 2-4 The shearing fixed blade 9 is rotatably connected to the shearing moving blade 8. The upper end of the cylindrical housing 1 is provided with a drive assembly for driving the shearing moving blade 8 to shear palm branches and leaves. The drive assembly includes an electric push rod 16, which is fixedly connected inside the cylindrical housing 1. A drive square rod 3 is slidably connected to the upper end of the cylindrical housing 1. The output end of the electric push rod 16 is fixedly connected to the lower end of the drive square rod 3. A drive pin 11 is fixedly connected to the side of the drive square rod 3 near the shearing moving blade 8. A drive frame 7 is fixedly connected to the end of the shearing moving blade 8 near the drive square rod 3. The drive pin 11 passes through the drive frame 7. A terminal 6 is provided on one side of the cylindrical housing 1. The terminal 6 is electrically connected to the electric push rod 16. The terminal 6 can be easily connected to a mobile power supply and control circuit to provide power to the electric push rod 16 and control the extension and retraction of the electric push rod 16. The wiring method and control principle of the electric push rod 16 are well known to those skilled in the art and will not be described in detail here.

[0030] The output end of the electric push rod 16 extends and retracts, driving the drive square rod 3 to slide along the upper end of the cylindrical housing 1. The drive pin 11 on the drive square rod 3 moves synchronously within the drive frame 7 of the shearing blade 8, pushing the shearing blade 8 to rotate around the shearing fixed blade 9. The shearing blade 8 and the shearing fixed blade 9 cooperate to complete the shearing of palm branches and leaves.

[0031] Please see Figure 1 and Figure 5 The cylindrical shell 1 has a telescopic rod 5 at its lower end. The upper end of the outer rod of the telescopic rod 5 has a locking knob 23 for locking the telescopic length. A connecting component is provided between the telescopic end of the telescopic rod 5 and the lower end of the cylindrical shell 1. The connecting component includes a square hole sleeve 18 and a limiting block 13. The square hole sleeve 18 is fixedly connected to the lower end of the cylindrical shell 1. The limiting block 13 is fixedly connected to the telescopic end of the telescopic rod 5. A square plug rod 21 is fixedly connected to the upper end of the limiting block 13. The square plug rod 21 is slidably connected to the square hole sleeve 18. A locking hole 17 is provided on the lower end of one side of the square hole sleeve 18. A locking component is provided on the square plug rod 21 for cooperating with the locking hole 17. The telescopic rod 5 is used to adjust the cutting height during use, which is convenient for cutting palm branches and leaves of different heights. When adjusting the height, loosen the locking knob 23, and tighten the locking knob 23 after telescopic extension to lock the length.

[0032] The telescopic rod 5 and the cylindrical housing 1 are assembled by a connecting assembly. When connecting, the square plug rod 21 at the telescopic end of the telescopic rod 5 is inserted into the square hole sleeve 18 at the lower end of the cylindrical housing 1. The square structure prevents rotation and the limiting block 13 restricts the insertion depth. At the same time, the locking assembly can cooperate with the locking hole 17 at the lower end of the square hole sleeve 18 to lock and complete the stable connection between the two.

[0033] Please see Figure 6The locking assembly includes an inner mounting groove 22 formed between a square plug rod 21 and a limiting block 13. A pressing handle 19 is slidably connected to one side of the limiting block 13, and an L-shaped locking tongue 20 is slidably connected to one side of the square plug rod 21. The lower end of the L-shaped locking tongue 20 is fixedly connected to the pressing handle 19. A spring 4 is installed between the side of the inner mounting groove 22 away from the L-shaped locking tongue 20 and the end of the pressing handle 19 located inside the inner mounting groove 22. The end of the pressing handle 19 away from the spring 4 is arc-shaped.

[0034] When connecting the telescopic rod 5 to the cylindrical housing 1, first press the pressing handle 19 to compress the spring 4 and drive the L-shaped locking tongue 20 to retract into the square plug rod 21. Then, insert the square plug rod 21 into the square hole sleeve 18. After that, release the pressing handle 19, the spring 4 resets and pushes the component back, so that the L-shaped locking tongue 20 is engaged in the lock hole 17 to achieve locking.

[0035] When unlocking, press the pressing handle 19 to compress the spring 4 and drive the L-shaped locking tongue 20 to retract into the square plug rod 21, releasing the lock with the lock hole 17. At this time, the square plug rod 21 can be pulled out from the square hole sleeve 18.

[0036] The working principle of this utility model is as follows: When in use, first adjust the length of the telescopic rod 5 according to the height of the palm branches and leaves to be pruned. During adjustment, loosen the locking knob 23, and then pull the inner rod of the telescopic rod 5 to adjust the length. After the length adjustment is completed, tighten the locking knob 23 to lock the length. When cutting, the output end of the electric push rod 16 extends and retracts, driving the drive square rod 3 to slide along the upper end of the cylindrical shell 1. The drive pin 11 on the drive square rod 3 moves synchronously in the drive frame 7 of the cutting blade 8, pushing the cutting blade 8 to rotate around the cutting fixed blade 9. The cutting blade 8 and the cutting fixed blade 9 cooperate to complete the cutting action of the palm branches and leaves.

[0037] When it is necessary to manually cut the lower palm branches and leaves, press the pressing handle 19 to compress the spring 4 and drive the L-shaped locking tongue 20 to retract into the square plug rod 21, releasing the lock with the locking hole 17. At this time, the square plug rod 21 can be pulled out from the square hole sleeve 18, separating the telescopic rod 5 from the cylindrical housing 1. At this time, the cylindrical housing 1 can be held by hand to perform palm branch and leaf trimming work.

[0038] After the trimming work is completed, unscrew the hand nut 14 from the threaded post 12, and then remove the fixing plate 10, the fixed shearing blade 9 and the moving shearing blade 8 from the top of the cylindrical housing 1 for separate storage.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
