Description

Technical Field

[0001] This utility model relates to the field of branch pruning technology, and more specifically, to a forestry branch pruning device. Background Technology

[0002] In existing technologies, forestry pruning devices are widely used in orchards, woodlands, and other settings for efficient pruning of branches at heights or distances, reducing the dangers of manual tree climbing and improving operational efficiency. However, most current pruning devices still have certain limitations in their structural design, particularly in the inconvenience of adjusting the angle of the handheld lever. Firstly, most current forestry pruning devices use a fixed or single-adjustment handheld lever structure. In actual use, operators often need to frequently adjust the lever based on tree height, branch direction, and working angle. Because the angle of the handheld lever is not flexibly changeable or the adjustment mechanism is cumbersome, users can only coordinate their movements using their arms or body postures during pruning. This not only increases the intensity of operation but also easily leads to inaccurate pruning, especially when dealing with branches at higher or lower positions, where pruning efficiency significantly decreases.

[0003] Secondly, while some devices are designed with angle adjustment functions, they often use methods such as threaded tightening and snap-locking, making the adjustment process complex and time-consuming. Furthermore, frequent adjustments can easily lead to wear or inaccurate positioning, causing the rod to loosen and posing a safety hazard. Simultaneously, due to differences in height, strength, and usage habits among operators, fixed or inflexible handheld rod angles cannot meet individual operational needs, severely impacting the comfort and continuous operation capability of pruning work.

[0029] Please see Figures 1-5A forestry branch pruning device includes a repair component 1, a handle 2, a rotary repair mechanism, a rotary locking mechanism, and a stabilizing mechanism. The rotary repair mechanism includes a mounting frame 3 and a drive ring 4. A drive wheel 5 and a driven wheel 6 are mounted on one end face of the mounting frame 3. A transmission belt 7 connects the drive wheel 5 and the driven wheel 6. A drive wheel 8 is located at the top end of the driven belt. The drive ring 4 is rotatably limited and mounted on the top end of the mounting frame 3. The repair component 1 is mounted on the top end of the drive ring 4. The rotary locking mechanism includes a locking tube 9 and a locking rod 1. 0. A rotating insert 11 is rotatably installed on the side wall of the clamping pipe 9. A clamping groove 12 is opened on the outer wall of the clamping rod 10. A pressure ring 13 is directionally slidably installed on the outer wall of the clamping pipe 9. A connecting plate 14 is installed at the bottom end of the side wall of the clamping pipe 9. A return spring 15 is installed between the connecting plate 14 and the pressure ring 13. A push-receiving slope frame 16 is installed at the top end of the pressure ring 13. A rotating frame 17 is rotatably installed on the upper limit of the outer wall of the clamping pipe 9. The rotation of the rotating frame 17 causes the push-receiving slope frame 16 and the pressure ring 13 to move longitudinally.

[0030] In this embodiment, the rotary repair mechanism mainly realizes the rotation of the repair component 1. During operation, the drive motor 27 starts, driving the drive wheel 5 to rotate. The power is transmitted to the driven wheel 6 through the transmission belt 7. The drive wheel 8 at the top of the driven wheel 6 is connected to the drive ring 4, causing the drive ring 4 to rotate at its upper limit on the annular track 26. Since the repair component 1 is installed on top of the drive ring 4, the repair component 1 will rotate together with the drive ring 4, realizing all-round pruning of forest branches, improving work efficiency and pruning quality. The rotary locking mechanism is used to adjust and fix the angle between the handle rod 2 and the repair component 1. During operation... By rotating the rotating frame 17, the rotating frame 17 drives the push-slope frame 16 to push the pressure ring 13 to move longitudinally along the locking tube 9, compressing the return spring 15. When the pressure ring 13 moves into place, the rotating insert block 11 on the side wall of the locking tube 9 disengages from the slot 12 on the outer wall of the locking rod 10. At this time, the locking rod 10 can be adjusted to pass through different adjustment holes 25 on the turntable 24 to change the relative angle between the handle rod 2 and the rotating rod 23. When the rotating frame 17 rotates in the opposite direction, the return spring 15 pushes the pressure ring 13 and the push-slope frame 16 back into place, and the rotating insert block 11 re-embeds into the slot 12 of the locking rod 10, completing the angle locking.

[0031] The stabilizing mechanism includes a threaded ring 18 and a directional ring 19. The threaded ring 18 is threadedly connected to the outer wall of the retaining tube 9, and the directional ring 19 is directionally slidably installed on the outer wall of the retaining tube 9. A support spring 20 is installed on the directional ring 19, and multiple sets of support springs 20 are provided. A support groove 21 is opened on the rotating frame 17, and the support springs 20 extend into the support groove 21 in stages to make the rotating frame 17 rotate stably. The directional movement of the directional ring 19 makes the support springs 20 stably embedded in the support groove 21, so that the rotating frame 17 is fixed on the outer wall of the retaining tube 9.

[0032] In this embodiment, the stabilizing mechanism ensures that the position of the rotating frame 17 is stable and reliable. In the initial state, multiple sets of support springs 20 on the directional ring 19 extend into the support grooves 21 on the rotating frame 17 in stages to provide initial stability. When it is necessary to firmly fix the position of the rotating frame 17, the directional ring 19 is pushed along the clamping tube 9 by rotating the threaded ring 18 and using the thrust bearing 28 to move it in a directional manner, so that the support springs 20 are fully embedded in the support grooves 21. At this time, the rotating frame 17 is fixed on the outer wall of the clamping tube 9 to prevent the angle from changing due to vibration or external force during operation, thus ensuring the accuracy and safety of the trimming operation.

[0033] Please see Figures 1-5 As a supplementary embodiment of a forestry branch pruning device with a rotating repair mechanism, a rotating clamping mechanism, and a stabilizing mechanism: A support plate 22 is installed at one end of the handle rod 2, a rotating rod 23 is installed at one end of the mounting frame 3, and a turntable 24 is installed at one end of the rotating rod 23. The support plate 22 and the turntable 24 are rotatably connected. The connecting plate 14 on the side wall of the clamping tube 9 is fixedly installed on the support plate 22. An adjustment hole 25 is provided on the turntable 24. Multiple sets of adjustment holes 25 are provided. One end of the clamping rod 10 can pass through different adjustment holes 25 to fix the turntable 24 of the support plate 22 relatively. Adjust the rotation angle position of the handle rod 2 and the rotating rod 23. A ring rail 26 is installed at the top end of the mounting frame 3 to drive the ring 4 to rotate and be mounted on the ring rail 26. A drive motor 27 is installed on the mounting frame 3 and is connected to the drive wheel 5. A thrust bearing 28 is installed at the bottom end of the threaded ring 18, and the bottom end face of the thrust bearing 28 is in contact with the top end of the directional ring 19.

[0034] More specifically, firstly, the operator holds the handle rod 2 and adjusts the angle between the handle rod 2 and the repair component 1 by rotating the locking mechanism according to the pruning requirements. During adjustment, the rotating frame 17 is rotated to move the pressure ring 13, causing the rotating insert 11 to disengage from the slot 12. The locking rod 10 is then passed through different adjustment holes 25. The rotating frame 17 is rotated in the opposite direction to re-embed the rotating insert 11 into the slot 12 to complete the locking. Then, the threaded ring 18 is rotated by the stabilizing mechanism to fully embed the support spring 20 into the support groove 21, ensuring the angle is fixed. Finally, the drive motor 27 is started, and the repair component 1 is rotated by rotating the repair mechanism to efficiently prune forest branches. This makes the pruning device adjustable in angle, reliable in fixation, and flexible in operation, greatly improving the efficiency and quality of forest pruning work.

[0035] In summary, when the overall equipment is in use or running: when the rotating repair mechanism is required to run, the rotating repair mechanism mainly realizes the rotation of the repair component 1. During operation, the drive motor 27 starts, driving the drive wheel 5 to rotate, and transmitting power to the driven wheel 6 through the transmission belt 7. The drive wheel 8 at the top of the driven wheel 6 is connected to the drive ring 4, causing the drive ring 4 to rotate at the upper limit of the circular rail 26. Since the repair component 1 is installed on the top of the drive ring 4, the repair component 1 will rotate together with the drive ring 4, realizing all-round pruning of forest branches, improving work efficiency and pruning quality.

[0036] When the locking mechanism needs to be rotated, it is used to adjust and fix the angle between the handle rod 2 and the repair assembly 1. During operation, by rotating the rotating frame 17, the rotating frame 17 drives the push slope frame 16 to push the pressure ring 13 to move longitudinally along the locking tube 9, compressing the return spring 15. When the pressure ring 13 moves into place, the rotating insert block 11 on the side wall of the locking tube 9 disengages from the slot 12 on the outer wall of the locking rod 10. At this time, the locking rod 10 can be adjusted to pass through different adjustment holes 25 on the turntable 24 to change the relative angle between the handle rod 2 and the rotating rod 23. When the rotating frame 17 rotates in the opposite direction, the return spring 15 pushes the pressure ring 13 and the push slope frame 16 back into place, and the rotating insert block 11 re-embeds into the slot 12 of the locking rod 10, completing the angle locking.

[0037] When the stabilizing mechanism is required to operate, it ensures that the position of the rotating frame 17 is stable and reliable. In the initial state, multiple sets of support springs 20 on the directional ring 19 extend into the support grooves 21 on the rotating frame 17 in stages to provide initial stability. When it is necessary to firmly fix the position of the rotating frame 17, the directional ring 19 is pushed along the clamping pipe 9 by rotating the threaded ring 18 and using the thrust bearing 28 to move it in a directional manner, so that the support springs 20 are fully embedded in the support grooves 21. At this time, the rotating frame 17 is fixed on the outer wall of the clamping pipe 9 to prevent angle changes caused by vibration or external force during operation, thus ensuring the accuracy and safety of the trimming operation.

[0038] First, the operator holds the handle rod 2 and adjusts the angle between the handle rod 2 and the repair component 1 by rotating the locking mechanism according to the pruning requirements. During adjustment, the rotating frame 17 is rotated to move the pressure ring 13, causing the rotating insert 11 to disengage from the slot 12. The locking rod 10 is then passed through different adjustment holes 25. The rotating frame 17 is rotated in the opposite direction to re-embed the rotating insert 11 into the slot 12 to complete the locking. Then, the threaded ring 18 is rotated by the stabilizing mechanism to fully embed the support spring 20 into the support groove 21, ensuring the angle is fixed. Finally, the drive motor 27 is started, and the repair component 1 is rotated by rotating the repair mechanism to efficiently prune forest branches. This pruning device features adjustable angle, reliable fixation, and flexible operation, greatly improving the efficiency and quality of forest pruning work.
