Description
Technical Field
[0001] This utility model belongs to the technical field of high-altitude pruning machines, and in particular relates to a high-altitude pruning machine suitable for confined spaces. Background Technology
[0002] Urban landscape trees, also known as solitary trees, specimen trees, or single-planted trees, are seedlings specifically used in urban construction, park greening, and municipal greening projects to beautify the scenery and green the environment. Urban landscape trees require maintenance treatments for long-term use, including cutting, pruning, and harvesting. Therefore, high-altitude pruning machines are needed for their pruning.
[0003] Traditional aerial pruning equipment (such as vehicle-mounted hydraulic pruning machines and backpack electric pruning shears) generally suffers from large size and fixed structure. For example, vehicle-mounted equipment requires a lane width of at least 2.5 meters to pass through, while in narrow residential lanes, dense forests, or gaps between buildings (such as lanes ≤ 1.8 meters wide), existing equipment often cannot enter due to limited boom extension range or excessive vehicle size. Although some equipment uses a telescopic boom design, the joint angle is fixed, making it difficult to navigate around obstacles such as protruding walls or utility poles. Utility Model Content

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0017] This embodiment provides a high-altitude tree pruning machine suitable for confined spaces. The high-altitude tree pruning machine is small in size and can effectively carry out tree maintenance work in confined spaces, making it more practical. In addition, its working arm adopts a telescopic structure design, and the joint's range of motion can be adjusted, so it is more flexible in actual use, can bypass most obstacles, and improve the efficiency of tree work.
[0018] Combination Figures 1 to 4 As shown, the high-altitude pruning machine of this embodiment includes a mobile chassis 10, a first telescopic arm 20, a second telescopic arm 30, a rotary driver 40, and a pruning section 50. The mobile chassis 10 enables the entire machine to move, and the first telescopic arm 20, the second telescopic arm 30, and the rotary driver 40 enable the adjustment of the position of the pruning section 50 so that the pruning section 50 can perform maintenance work on the trees.
[0019] In this embodiment, a plurality of casters 60 are connected to the bottom of the mobile chassis 10. Each caster 60 has a drive unit (the drive unit is an internal structure of the caster 60, not shown in the figure) to drive the mobile chassis 10. The casters 60 are connected to the mobile chassis 10 through support legs 70. The support legs 70 are L-shaped structures and have a steering unit (the steering unit is an internal structure of the support legs 70, not shown in the figure) to effectively steer the support legs 70. Therefore, while supporting the mobile chassis 10, the support legs 70 can also drive the mobile chassis 10 to steer, improving the flexibility of the mobile chassis 10.
[0020] Combination Figure 1 and Figure 2As shown, in this embodiment, a first base 11 is provided on the mobile chassis 10, a first telescopic arm 20 is movably mounted on the first base 11, a second base 21 is provided at the end of the first telescopic arm 20, a second telescopic arm 30 is movably mounted on the second base 21, a third base 31 is provided at the end of the second telescopic arm 30, and a rotation driver 40 is movably mounted on the third base 31. A rotation bracket 41 is provided at the driving end of the rotation driver 40. In this embodiment, both the first telescopic arm 20 and the second telescopic arm 30 are multi-section telescopic arms, which can realize the length change of the first telescopic arm 20 and the second telescopic arm 30. The rotation driver 40 is a motor or a rotating hydraulic cylinder. Both the first telescopic arm 20 and the second telescopic arm 30 can extend and retract the pruning part 50 and make fine adjustments to its angle, while the rotation driver 40 can rotate and adjust the pruning part 50 as a whole, changing the position of the pruning part 50 for pruning operations.
[0021] In this embodiment, the bottom of the first telescopic arm 20 is hinged to the first base 11. A first luffing cylinder 80 is provided on the first base 11. The piston rod of the first luffing cylinder 80 is connected to the bottom of the first telescopic arm 20 to move the first telescopic arm 20 relative to the first base 11. The bottom of the second telescopic arm 30 is hinged to the second base 21. A second luffing cylinder 90 is provided on the second base 21. The piston rod of the second luffing cylinder 90 is connected to the bottom of the second telescopic arm 30 to move the second telescopic arm 30 relative to the second base 21. After the first luffing cylinder 80 is activated, it can drive the first telescopic arm 20 to change the deflection angle of the first telescopic arm 20, thereby changing the position of the pruning part 50. The second luffing cylinder 90 can drive the second telescopic arm 30 to change the deflection angle of the second telescopic arm 30, thereby changing the position of the pruning part 50.
[0022] Combination Figure 3 and Figure 4 As shown, the pruning unit 50 in this embodiment includes a pruning driver 51 and a chainsaw 52. The pruning driver 51 is mounted on a rotating bracket 41, and the chainsaw 52 is mounted on the driving end of the pruning driver 51. The pruning driver 51 is hinged to the rotating bracket 41. An angle driver 120 is provided on the rotating bracket 41 to deflect the pruning driver 51 at an angle. In this embodiment, the pruning driver 51 is a motor or a rotating hydraulic cylinder, and the angle driver 120 is a hydraulic cylinder or an electric cylinder. Since the pruning driver 51 is hinged to the rotating bracket 41, the angle driver 120 can push the pruning driver 51 to deflect the pruning driver 51 at an angle, thereby changing the angle of the chainsaw 52.
[0023] In this embodiment, the rotary driver 40 is hinged to the third base 31. Two opposing swing drivers 100 are provided on the third base 31 to swing the rotary driver 40 at an angle. The rotary driver 40 is connected to the third base 31 via a rotating shaft 110, and the swing driver 100 is connected to the rotating shaft 110 via a swing block. In this embodiment, the swing driver 100 is a hydraulic cylinder or an electric cylinder. The swing driver 100 drives the rotating shaft 110 to rotate. The rotating shaft 110 drives the rotary driver 40 to rotate, thus changing the angle of the rotary driver 40 and realizing the angle adjustment of the pruning section 50.
[0024] Furthermore, in this embodiment, the swing angle of the swing driver 100 is ±90°, and the initial installation position of the two swing blocks is at an angle of 45° with the longitudinal axis of the second telescopic arm 30, thereby enabling flexible adjustment of the pruning section 50.
[0025] In practical use, the high-altitude pruning machine of this embodiment uses the first telescopic arm 20, the second telescopic arm 30, and the rotation driver 40 to adjust the pruning part 50 at a large angle, and the swing driver 100 and the angle driver 120 to adjust the pruning part 50 at a small angle. This achieves flexible adjustment of the pruning part 50, meets the usage requirements of the high-altitude pruning machine, and has a small size, which can effectively carry out tree maintenance work in a narrow space, making it more practical.
[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
