Description

Technical Field

[0001] This utility model relates to the field of tree pruning equipment technology, and in particular to an automatic pruning machine for garden landscape trees. Background Technology

[0002] Tree pruning is a crucial aspect of modern landscape construction and maintenance. With the continuous expansion of urban green spaces and the increasing demands for refined landscape management, traditional manual pruning methods, due to their low efficiency and high labor intensity, are no longer sufficient to meet practical needs. Therefore, automatic tree pruning machines for landscapes have emerged, effectively improving pruning efficiency and reducing labor costs, becoming an important development direction in the field of landscape maintenance.

[0003] Existing automatic tree pruning machines for landscaping mostly employ a fixed robotic arm structure, with pruning blades mounted at the end of the arm. The extension, retraction, and oscillation of the robotic arm are controlled by hydraulic or electric drive devices, thereby driving the pruning blades to perform the pruning operation. Some machines are also equipped with a simple angle adjustment mechanism, typically using bolts or locking slots to adjust the angle of the pruning blades within a certain range to accommodate pruning branches at different heights and directions.

[0004] However, existing automatic pruning machines, whose blade angle adjustment mechanisms are mostly fixed-angle limit or manual adjustment modes, struggle to adjust the blade angle in real time and flexibly according to the complex and ever-changing growth patterns of trees. In actual pruning operations, situations often arise where some branches are difficult to reach due to unsuitable pruning angles, or where operators need to frequently stop the machine to manually adjust the angle. This not only reduces pruning efficiency but also increases the workload of operators, failing to meet the needs of refined and efficient pruning of landscape trees. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic pruning machine for garden landscape trees, which aims to improve the problem that existing automatic pruning machines, whose pruning blade angle adjustment mechanisms are mostly fixed angle limit or manual adjustment modes, are unable to adjust the pruning blade angle in real time and flexibly according to the complex and ever-changing growth form of trees.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic tree pruning machine for garden landscapes, comprising a pruning machine body, a fixing plate fixedly connected to the outer wall of the pruning machine body, a support frame one fixedly connected to the upper surface of the fixing plate, an mounting plate fixedly connected to the upper surface of the support frame one, a support frame two fixedly connected to the upper surface of the mounting plate, and an adjustment component provided above the support frame two;

[0007] The adjustment assembly includes an adjustment plate, which is disposed above the second support frame. A first connecting shaft is fixedly connected to the outer wall of the adjustment plate, and an arc-shaped plate is slidably connected to the outer wall of the first connecting shaft. An electric push rod is fixedly connected to the upper surface of the mounting plate, and the output end of the electric push rod is fixedly connected to the adjustment plate. A second connecting shaft is fixedly connected to the outer wall of the adjustment plate, and a connecting plate is rotatably connected to the outer wall of the second connecting shaft.

[0008] Furthermore, a support plate is fixedly connected to the outer wall of the adjusting plate, a motor is fixedly connected to the outer wall of the support plate, a threaded rod is fixedly connected to the output end of the motor, a movable plate is threadedly connected to the outer wall of the threaded rod, and a guide rod is fixedly connected to the outer wall of the movable plate.

[0009] Furthermore, a second support plate is fixedly connected to the outer wall of the movable plate, a second motor is fixedly connected to the outer wall of the second support plate, and a trimming blade is fixedly connected to the output end of the second motor.

[0010] Furthermore, the outer wall of the guide rod is slidably connected to the inner wall of the adjusting plate, and the threaded rod is rotatably connected to the inner wall of the adjusting plate.

[0011] Furthermore, the outer wall of the movable plate is slidably connected to the inner wall of the adjusting plate, and the motor is located on one side of the outer wall of the adjusting plate.

[0012] Furthermore, the lower surface of the connecting plate is fixedly connected to the upper surface of the second support frame.

[0013] Furthermore, the arc-shaped plate is positioned above the mounting plate.

[0014] Furthermore, the adjusting plate is attached to the outer wall of the connecting plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the pruning blade can be flexibly adjusted at multiple angles. The electric push rod pushes the adjustment plate to move. The cooperation between the connecting shaft one and the arc plate, and the connecting shaft two and the connecting plate, enables the adjustment plate to drive the pruning blade to change angles without manual adjustment. This greatly improves the convenience and efficiency of pruning operations, can quickly adapt to the growth form and pruning needs of different trees, and reduces the labor intensity of garden pruning work.

[0017] 2. In this utility model, the length of the moving plate and the pruning blade is adjusted by the rotation of the threaded rod driven by the motor. The guide rod provides stable guidance for the movement. With the help of the angle adjustment structure, the pruning blade can be precisely adjusted in multiple dimensions, which can meet the needs of tree pruning work in different scenarios. Whether it is the pruning of high branches and leaves or the pruning of complex shapes, it can be easily handled, which significantly improves the applicability and professionalism of garden landscape tree pruning.

Detailed Implementation

[0025] 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.

[0026] Reference Figures 1-4 An embodiment of this utility model is provided: an automatic tree pruning machine for garden landscapes, including a pruning machine body 1, a fixing plate 2 fixedly connected to the outer wall of the pruning machine body 1 for securely installing a support frame 3 on the pruning machine body 1, a support frame 3 fixedly connected to the upper surface of the fixing plate 2, an mounting plate 4 fixedly connected to the upper surface of the support frame 3, a support frame 5 fixedly connected to the upper surface of the mounting plate 4, and an adjustment component provided above the support frame 5.

[0027] The adjustment assembly includes an adjustment plate 8, which, through cooperation with components such as connecting shaft 7, connecting shaft 11, and electric push rod 9, achieves its own rotation and movement, thereby driving the trimming blade 19 to adjust its angle and position. The adjustment plate 8 is positioned above the support frame 2 5. The connecting shaft 7 is fixedly connected to the outer wall of the adjustment plate 8 and slidably connected to the arc plate 6, connecting the adjustment plate 8 and the arc plate 6. When the electric push rod 9 pushes the adjustment plate 8 to move, it slides within the arc plate 6, causing the adjustment plate 8 to rotate. The arc plate 6 is slidably connected to the outer wall of the connecting shaft 7, providing a sliding track for the connecting shaft 7. By restricting the movement trajectory of the connecting shaft 7, when the adjustment plate 8 moves upward, it guides the adjustment plate 8 to rotate around a specific arc, thereby achieving... For precise adjustment of the trimmer blade 19 angle, an electric push rod 9 is fixedly connected to the upper surface of the mounting plate 4. Through telescopic movement, it generates pushing or pulling force, directly driving the adjustment plate 8 to move up or down. The output end of the electric push rod 9 is fixedly connected to the adjustment plate 8. A connecting shaft 2 11 is fixedly connected to the outer wall of the adjustment plate 8. The connecting shaft 2 11 provides a rotation shaft for the rotation of the adjustment plate 8. With the sliding of the connecting shaft 1 7, the adjustment plate 8 can rotate flexibly, ensuring the smoothness and stability of the trimmer blade 19 angle adjustment. A connecting plate 10 is rotatably connected to the outer wall of the connecting shaft 2 11, providing support and guidance for the rotation of the adjustment plate 8, ensuring that the adjustment plate 8 will not shake or deviate during rotation, making the trimmer blade 19 angle adjustment more stable and reliable.

[0028] Specifically, firstly, the electric push rod 9 is activated, and its output end generates thrust to move the adjusting plate 8 upward. During the upward movement of the adjusting plate 8, the connecting shaft 7, which is fixedly connected to the outer wall of the adjusting plate 8, slides along the inside of the arc plate 6. The arc plate 6 provides a track constraint for the sliding of the connecting shaft 7. At the same time, the connecting shaft 11, which is on the outer wall of the adjusting plate 8, rotates inside the connecting plate 10. The connecting plate 10 provides support and guidance for the rotation of the connecting shaft 11. The sliding of the connecting shaft 7 and the rotation of the connecting shaft 11 cooperate with each other, enabling the adjusting plate 8 to rotate. Since the pruning blade 19 is installed on the linkage component of the adjusting plate 8, the rotation of the adjusting plate 8 can drive the pruning blade 19 to move. By controlling the extension and retraction length of the electric push rod 9, the rotation angle of the adjusting plate 8 can be precisely changed, thereby achieving the effect of adjusting the angle of the pruning blade 19 to adapt to the growth form and pruning needs of different trees.

[0029] Reference Figure 3 and Figure 5A support plate 12 is fixedly connected to the outer wall of the adjusting plate 8. A motor 13 is fixedly connected to the outer wall of the support plate 12. A threaded rod 14 is fixedly connected to the output end of the motor 13, converting the rotational motion of the motor 13 into the linear motion of the moving plate 15. The moving plate 15 moves along the inner wall of the adjusting plate 8 through its own rotation, thereby adjusting the position of the trimming blade 19 in the length direction. The moving plate 15 is threadedly connected to the outer wall of the threaded rod 14 and moves along the inner wall of the adjusting plate 8 under the drive of the threaded rod 14. A guide rod 16 is fixedly connected to the outer wall of the moving plate 15, sliding inside the adjusting plate 8 and cooperating with the guide hole on the inner wall of the adjusting plate 8 to guide the movement of the moving plate 15 and prevent the moving plate 15 from shifting or shaking during movement. A support plate 17 is fixedly connected, and a motor 18 is fixedly connected to the outer wall of the support plate 17. A pruning blade 19 is fixedly connected to the output end of the motor 18. Driven by the motor 18, the blade rotates at high speed to cut and prune the branches and leaves of the garden trees. The angle of the adjustment plate 8 and the length of the moving plate 15 can be adjusted to meet the pruning needs of trees in different scenarios. The outer wall of the guide rod 16 is slidably connected to the inner wall of the adjustment plate 8, the threaded rod 14 is rotatably connected to the inner wall of the adjustment plate 8, and the outer wall of the moving plate 15 is slidably connected to the inner wall of the adjustment plate 8. The motor 13 is set on one side of the outer wall of the adjustment plate 8. The lower surface of the connecting plate 10 is fixedly connected to the upper surface of the support frame 2 5. The arc plate 6 is set above the mounting plate 4, and the adjustment plate 8 is attached to the outer wall of the connecting plate 10.

[0030] Specifically, by starting motor 13, the output end of motor 13 drives the threaded rod 14 to rotate. The outer wall of the threaded rod 14 is threaded, which meshes with the thread on the inner wall of the moving plate 15. When the threaded rod 14 rotates, it drives the moving plate 15 to move on the inner wall of the adjusting plate 8. The guide rod 16, which is fixedly connected to the outer wall of the moving plate 15, slides inside the adjusting plate 8. The guide rod 16 cooperates with the guide hole on the inner wall of the adjusting plate 8 to guide the movement of the moving plate 15 and prevent the moving plate 15 from deviating during the movement. By controlling the number of rotations and direction of motor 13, the moving distance of the moving plate 15 is precisely controlled, thereby realizing the position adjustment of the pruning blade 19. After the position of the pruning blade 19 is adjusted, motor 2 can be started. The output end of motor 2 can drive the pruning blade 19 to rotate at high speed, using the cutting ability of the blade to prune the tree branches and leaves. Through dual adjustment of angle and length, it can adapt to tree pruning work in different scenarios.

[0031] Working principle: When the automatic tree pruning machine for garden landscape needs to be used, first start the electric push rod 9. The output end of the electric push rod 9 pushes the adjusting plate 8 to move upward. The connecting shaft 7 on the outer wall of the adjusting plate 8 slides along the inside of the arc plate 6. The connecting shaft 11 on the outer wall of the adjusting plate 8 rotates inside the connecting plate 10. The rotation of the adjusting plate 8 can drive the pruning blade 19 to move, thereby achieving the effect of adjusting the angle of the pruning blade 19.

[0032] In addition, when it is necessary to adjust the length of the trimming blade 19, the motor 13 is started. The output end of the motor 13 drives the threaded rod 14 to rotate. The rotation of the threaded rod 14 will drive the moving plate 15 to move on the inner wall of the adjusting plate 8, thereby moving the trimming blade 19. The guide rod 16 slides inside the adjusting plate 8 to guide the movement of the moving plate 15. After the position of the trimming blade 19 is adjusted, the motor 2 18 can be started. The output end of the motor 2 18 drives the trimming blade 19 to rotate, thereby adapting to tree trimming in different scenarios.

[0033] 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.
