Description

Technical Field

[0001] This utility model relates to the field of forestry machinery technology, and in particular to a high-altitude tree branch pruning device for forestry maintenance. Background Technology

[0002] High-altitude tree pruning devices are key equipment in forestry maintenance, mainly used to treat dead and diseased branches at high points on trees. They can replace manual climbing, ensuring operational safety and improving pruning efficiency. They typically need to balance operational flexibility and ease of use to adapt to different tree shapes and pruning scenarios.

[0003] Traditional equipment mainly includes high-branch pruning carts, lithium-ion high-branch saws, and handheld pruning tools. High-branch pruning carts complete the work by adjusting the position with a robotic arm. Lithium-ion high-branch saws consist of a telescopic rod, a motor, and a saw head. The telescopic rod extends the working range, and the motor drives the saw head to cut. Handheld pruning tools require the operator to hold them directly and adjust the pruning angle manually.

[0004] Currently, the support structure of handheld trimming equipment is clearly inadequate, lacking stable auxiliary support components. Operators need to continuously use their arms to bear the weight and maintain balance, which can easily lead to arm fatigue during long-term operation. At the same time, some simple brackets cannot be flexibly adjusted in position, making it difficult to adapt to operators of different heights and varying trimming angles, thus limiting the flexibility of operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-altitude tree branch pruning device for forestry maintenance, which aims to improve the problems of insufficient support, heavy load-bearing capacity, difficulty in adjusting the bracket, and limited flexibility of existing handheld pruning equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-altitude tree branch pruning device for forestry maintenance includes an auxiliary support bracket. A fixing and tightening strap is fixedly connected to one side of the auxiliary support bracket. A sliding groove is opened inside the auxiliary support bracket. A sliding support assembly is slidably connected to the inner wall of the sliding groove. An automatic telescopic assembly is rotatably connected to the top of the sliding support assembly. A switchable shearing saw is fixedly connected to the top of the automatic telescopic assembly. As a further description of the above technical solution: The switchable shears includes a switching motor, the drive end of which is threadedly connected to a base, a hand saw is fixedly connected to one side of the base, a branch shears are fixedly connected to one side of the base, and a drive motor is fixedly connected to the outer wall of the base. As a further description of the above technical solution: The drive end of the drive motor is fixedly connected to a drive gear, and a pair of shears is meshed with the outer side of the drive gear. As a further description of the above technical solution: The outer side of the pruning shears is rotatably connected to the inner wall of the pruning shears, and the bottom of the pruning shears is provided with gear teeth, the outer side of the gear teeth being meshed with the outer side of the drive gear. As a further description of the above technical solution: The automatic telescopic assembly includes a rod body, a telescopic motor is fixedly connected to the top of the rod body, a telescopic gear is fixedly connected to the drive end of the telescopic motor, a telescopic rod is meshed with the outer side of the telescopic gear, and the top of the telescopic rod is fixedly connected to one side of the switching motor. As a further description of the above technical solution: The sliding support assembly includes a sliding joint, a support rod is rotatably connected to the top of the sliding joint, and a steering joint is rotatably connected to the top of the support rod. As a further description of the above technical solution: The steering joint includes a steering seat, the bottom of which is rotatably connected to the top of a support rod. A groove is provided inside the steering seat, and a connecting joint is rotatably connected to the top of the steering seat. As a further description of the above technical solution: The bottom of the connecting joint is provided with a rotating protrusion, the outer wall of the rotating protrusion is slidably connected to the inner wall of the groove, and the top of the steering joint is rotatably connected to the bottom of the automatic telescopic component.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the sliding support component drives the rotation and sliding of the sliding joint, which in turn drives the automatic telescopic component to flexibly adjust the working angle and position. Combined with the switchable shears, the switching motor drives the base to rotate, realizing the rapid switching between the hand saw and the pruning shears, meeting the pruning needs of branches of different thicknesses, and improving the adaptability and efficiency of the operation.

[0008] 2. In this utility model, the auxiliary support bracket is stably fixed to the operator's body by a fixed tightening strap. The sliding support component and the automatic telescopic component share the weight of the pruning tool. At the same time, the drive motor drives the pruning shears to make precise cuts through the drive gear, which reduces the burden on the operator and improves the pruning accuracy and operation safety.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a high-altitude tree branch pruning device for forestry maintenance, comprising an auxiliary support bracket 1. A fixing and tightening strap 2 is fixedly connected to one side of the auxiliary support bracket 1. The fixing and tightening strap 2 reliably fixes the auxiliary support bracket 1 to the operator's body. By tightening, the bracket is stably connected to the human body, preventing shaking or displacement of the device during operation and ensuring operational stability and safety. The auxiliary support bracket 1 has a sliding groove 3 inside. A sliding support component 4 is slidably connected to the inner wall of the sliding groove 3. The sliding support component 4 slides within the sliding groove 3 and also has the function of rotation and posture adjustment, increasing operational flexibility. The sliding support assembly 4 includes a sliding joint 19, with a support rod 20 rotatably connected to the top of the sliding joint 19. A steering joint 21 is rotatably connected to the top of the support rod 20. The steering joint 21 includes a steering seat 22, with the bottom of the steering seat 22 rotatably connected to the top of the support rod 20. A groove 23 is provided inside the steering seat 22, and a connecting joint 24 is rotatably connected to the top of the steering seat 22. Through the rotational cooperation of the steering seat 22 and the connecting joint 24, the working direction can be changed, allowing the device to be aligned with branches in different directions for pruning, thus increasing the flexibility of the operation. A rotating protrusion 25 is provided at the bottom of the connecting joint 24. The outer wall of the rotating protrusion 25 is slidably connected to the inner wall of the groove 23. The top of the steering joint 21 is rotatably connected to the bottom of the automatic telescopic assembly 5. The top of the sliding support assembly 4 is rotatably connected to the automatic telescopic assembly 5. The automatic telescopic assembly 5 includes a rod 15. A telescopic motor 16 is fixedly connected to the top of the rod 15. A telescopic gear 17 is fixedly connected to the drive end of the telescopic motor 16. A telescopic rod 18 is meshed with the outer side of the telescopic gear 17. The top of the telescopic rod 18 is fixedly connected to one side of the switching motor 7. The telescopic rod 18, through cooperation with the rod 15, moves linearly along the rod 15 under the drive of the telescopic gear 17, changing the overall length of the automatic telescopic assembly 5, thereby adjusting the working height of the switchable shears 6 and expanding the range of the device for pruning high-altitude tree branches.

[0013] Reference Figure 1 , Figure 3 and Figure 4The top of the automatic telescopic assembly 5 is fixedly connected to a switchable shearing saw 6. The switchable shearing saw 6 includes a switching motor 7, the drive end of which is threadedly connected to a base 8. A hand saw 9 and a branch shear 10 are fixedly connected to one side of the base 8. The switchable shearing saw 6 integrates the functions of both the hand saw 9 and the branch shear 10. Controlled by the switching motor 7, the working states of the hand saw 9 and the branch shear 10 can be quickly switched as needed to meet the needs of pruning branches of different thicknesses and shapes. A drive motor 11 is fixedly connected to the outer wall of the base 8. A drive gear 12 is fixedly connected to the drive end of the drive motor 11. A branch shear 13 is meshed with the outer side of the drive gear 12. The drive motor 11 drives the drive gear 12 to complete the movement of the branch shear 13, realizing the cutting action. The outer side of the pruning shears 13 is rotatably connected to the inner wall of the pruning shears 10. The bottom of the pruning shears 13 is provided with gear teeth 14. The outer side of the gear teeth 14 is meshed with the outer side of the drive gear 12. The gear teeth 14 convert the rotation of the drive gear 12 into the swing of the pruning shears 13, realizing the power connection of the cutting action.

[0014] Working Principle: First, when the forestry maintenance high-altitude tree pruning device is in operation, the auxiliary support bracket 1 is securely bound to the operator's body via the fixing and tightening strap 2, providing a stable support foundation for subsequent operations. The sliding support component 4 slides and rotates flexibly within the slide groove 3, driving the automatic telescopic component 5 to adjust its position and angle. The telescopic motor 16 in the automatic telescopic component 5 drives the telescopic gear 17 to rotate, and through the cooperation of the telescopic rod 18 and the rod body 15, the length is extended or retracted, further changing the working height of the switchable shears 6 to adapt to branches of different heights. Depending on the needs, the switchable shears 6 is driven by the switching motor 7 to rotate the base 8, completing the function switch between the hand saw 9 and the pruning shears 10. The drive motor 11 drives the drive gear 12, which meshes with the bottom gear teeth 14 of the pruning shears 13, enabling the pruning shears 10 to cut. The hand saw 9 then directly performs the sawing action manually or with the help of a motor, precisely processing high-altitude branches.

[0015] In the sliding support assembly 4, the sliding joint 19, support rod 20, and steering joint 21 cooperate with each other. The sliding joint 19 slides in the groove 3 and adjusts its posture, transmitting the signal to the steering joint 21 via the support rod 20. The steering seat 22, connecting joint 24, rotating protrusion 25, and groove 23 work together to achieve multi-directional steering, allowing the automatic telescopic assembly 5 and the switchable shears 6 to flexibly align with the branches. The automatic telescopic assembly 5 is based on the rod body 15, with the telescopic motor 16, telescopic gear 17, and telescopic rod 18 working in tandem to precisely control the working length. In the switchable shears 6, the switching motor 7 quickly switches between the hand saw 9 and the pruning shears 10, the drive motor 11 outputs power to the pruning shears 10, and the drive gear 12 meshes with the gear teeth 14 of the pruning shears 13 to ensure stable cutting. All the structures are interlocked, efficiently completing the high-altitude tree pruning operation.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
