Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, and in particular to a landscaping pruning machine. Background Technology

[0002] Landscape greening is the process of creating beautiful environments suitable for people's living through pruning, transplanting, and planning. Landscape greening is required for the construction of parks, community greening, road greening, and private villa construction. In the process of landscape greening, mowing machines are commonly used tools. For example, after the lawn is laid, a mowing machine is needed to trim the lawn to the same height and length to ensure the lawn's appearance.

[0003] In the prior art, such as the garden greening trimmer described in Chinese Patent No. CN202223492296.2, the following features: a base, a push handle on one side of the base, and a rotatable lifting device on the base. The lifting device includes a cuboid box with a strip-shaped opening on one side. The length direction of the strip-shaped opening is in the same plane as the length direction of the cuboid box. A first motor is fixedly installed on the upper end face of the cuboid box. Two uprights and a rotating shaft are provided between the upper and lower end faces of the cuboid box. Sliding blocks are slidably fitted on the rotating shaft and the uprights. The sliding blocks have a first through hole for the rotating shaft to pass through and a second through hole for the uprights to pass through. This invention can adjust the height of lawn trimming and can also trim green plants with curved shapes.

[0004] While the aforementioned solution offers the advantages described, its angle adjustment mechanism employs a "boom-tilting" design. In this mode, the entire structure, including the lifting mechanism and its supporting heavy components such as the motor and blades, must rotate synchronously. It's worth noting that because the lifting mechanism is located within the tilting component, the overall structure is relatively complex. This design feature directly results in a large mass and moment of inertia during system movement, leading to poor overall stability. Especially when performing angle adjustment operations or working on rough terrain, the equipment is highly susceptible to dynamic response imbalances, which can induce violent shaking and, in extreme cases, even tip over, posing a safety hazard. Utility Model Content

[0005] The purpose of this invention is to address the problem in existing technologies where the angle adjustment mechanism is a "tilting boom" design. In this design, the entire structure, including the lifting mechanism and its supporting heavy components such as the motor and blades, needs to rotate synchronously. It is worth noting that because the lifting mechanism is located within the tilting component, the overall structure is relatively complex. This design feature directly results in a large mass and moment of inertia during system movement, leading to poor overall stability. Especially when performing angle adjustment operations or working on rough terrain, the equipment is prone to dynamic response imbalances, causing severe shaking and, in extreme cases, overturning, posing a safety hazard.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a garden greening pruning machine: including a mounting base plate, the mounting base plate being trapezoidal, a push handle being fixedly connected to its rear end, a sliding frame being mounted on the top of the mounting base plate, a first mounting block being slidably connected inside the sliding frame, a servo electric cylinder being mounted on the mounting base plate, a connecting plate being fixedly connected to the output end of the servo electric cylinder, and the connecting plate being fixedly connected to the sliding frame; The end of the sliding frame is provided with a connecting frame, which is rotatably connected to the sliding frame via a first rotating shaft. The end of the connecting frame is fixedly connected to a second mounting block, and a motor is rotatably connected to the second mounting block. The output end of the motor is connected to a second rotating shaft. The second mounting block is provided with a through groove adapted to the movement of the second rotating shaft when the motor is tilted. The second rotating shaft passes through the through groove and is fixedly connected to a trimmer. The sliding frame is fixedly connected to a mounting box at the side end of the first rotating shaft. The mounting box contains a first control mechanism for controlling the rotation angle of the connecting frame.

[0007] The connecting frame is equipped with a second control mechanism for controlling the pitch angle of the motor.

[0008] In a preferred embodiment, the first control mechanism includes a worm gear and a worm wheel, the worm wheel being fixedly connected to a first rotating shaft, and the worm gear being rotatably connected inside the mounting box and meshing with the worm wheel.

[0009] In a preferred embodiment, the second control mechanism includes a groove, a threaded rod, a connecting block, a connecting rod, and a rotating handle. The groove is disposed on the connecting frame, the threaded rod is rotatably connected to the groove, the rotating handle is drivenly connected to the threaded rod through a bevel gear set, the connecting block is slidably connected to the groove and threadedly connected to the threaded rod, and the two ends of the connecting rod are rotatably connected to the connecting block and the motor, respectively.

[0010] In a preferred embodiment, the servo electric cylinder is fixedly connected to the sliding frame via a connecting plate, so that the telescopic movement of the servo electric cylinder drives the sliding frame to move in the vertical direction, resulting in a more compact overall structure.

[0011] In a preferred embodiment, the mounting base is equipped with a battery that provides power to the servo electric cylinder and the motor.

[0012] In a preferred embodiment, the lower end of the mounting base is provided with three evenly distributed casters to facilitate support of the device.

[0013] In a preferred embodiment, a throttle is also included, which is fixedly connected to the end of the worm gear to facilitate driving the thread to rotate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention fixes the main lifting mechanism (servo electric cylinder, sliding frame) to the base plate, and only drives the lightweight connecting frame and trimming components to change angles. This "fixed main body, moving end" design greatly reduces the mass and inertia of the moving parts, and fundamentally overcomes the risk of machine shaking and overturning caused by overall flipping.

[0017] 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.

[0018] Please see Figures 1-4 This embodiment provides a garden greening pruning machine, the specific concept of which is as follows: A garden greening pruning machine includes a mounting base plate 1, which is trapezoidal in shape. A push handle 3 is fixedly connected to its rear end. A sliding frame 4 is mounted on the top of the mounting base plate 1. A first mounting block 5 is slidably connected inside the sliding frame 4. A servo electric cylinder 6 is mounted on the mounting base plate 1. A connecting plate 7 is fixedly connected to the output end of the servo electric cylinder 6. The connecting plate 7 is fixedly connected to the sliding frame 4. The servo electric cylinder 6 is fixedly connected to the sliding frame 4 through the connecting plate 7, so that the extension and retraction motion of the servo electric cylinder 6 drives the sliding frame 4 to move in the vertical direction. The base plate 1 is welded to or bolted to a push handle 3 at its rear end for easy pushing by the operator. Three evenly distributed casters 2 are mounted at its lower end; these casters are self-locking swivel casters to ensure flexible movement of the equipment. When the servo electric cylinder 6 is working, it drives the entire sliding frame 4 to rise and fall smoothly in the vertical direction. A battery 20 is also placed on the mounting base plate 1 to provide power to the servo electric cylinder 6 and the subsequent motor 14. A connecting frame 8 is provided at the end of the sliding frame 4. The connecting frame 8 is rotatably connected to the sliding frame 4 via a first rotating shaft 9. A second mounting block 12 is fixedly connected to the end of the connecting frame 8. A motor 14 is rotatably connected to the second mounting block 12. A second rotating shaft 15 is connected to the output end of the motor 14. A through groove 13 is provided on the second mounting block 12 to adapt to the movement of the second rotating shaft 15 when the motor 14 is tilted. The second rotating shaft 15 passes through the through groove 13 and is fixedly connected to a trimmer 16. The sliding frame 4 is fixedly connected to the side end of the first rotating shaft 9 with a mounting box 21. The mounting box 21 is equipped with a first control mechanism for controlling the rotation angle of the connecting frame 8. The first control mechanism includes a worm 22 and a worm wheel 23. The worm wheel 23 is fixedly connected to the first rotating shaft 9, and the worm 22 is rotatably connected in the mounting box 21 and meshes with the worm wheel 23. To facilitate the operator's rotation of the worm gear 22, a handle 24 is also provided. The handle 24 is fixedly connected to the end of the worm gear 22, making it convenient for the user to adjust the force. When the operator rotates the throttle 24, the worm 22 drives the worm wheel 23 and the first rotating shaft 9 to rotate, thereby realizing the horizontal angle adjustment of the connecting frame 8. Due to the self-locking characteristics of the worm wheel and worm, the connecting frame 8 can be stably stopped in any position. A second control mechanism is provided on the connecting frame 8 to control the pitch angle of the motor 14; The second control mechanism includes a groove 11, a threaded rod 10, a connecting block 18, a connecting rod 17, and a handle 19. The groove 11 is set on the connecting frame 8. The threaded rod 10 is rotatably connected in the groove 11. The handle 19 is connected to the threaded rod 10 through a bevel gear set. The connecting block 18 is slidably connected in the groove 11 and threadedly connected to the threaded rod 10. The two ends of the connecting rod 17 are rotatably connected to the connecting block 18 and the motor 14, respectively. When the handle 19 is rotated clockwise or counterclockwise, the threaded rod 10 is driven to rotate via the bevel gear set. The rotational motion of the threaded rod 10 is converted into linear motion of the connecting block 18 along the groove 11. The movement of the connecting block 18 pushes or pulls the motor 14 via the connecting rod 17, causing it to pitch and swing about its hinge point on the second mounting block 12, ultimately achieving precise and stepless adjustment of the cutting angle of the trimmer 16. Similarly, the self-locking property of the threaded pair ensures that the angle will not change due to vibration after it is set.

[0019] Working principle: Height adjustment: Operate the control switch of the servo electric cylinder 6 to drive the sliding frame 4 to rise to the predetermined height.

[0020] Angle preset: Horizontal angle: Rotate the handle 24, which drives the connecting frame 8 and the trimmer 16 to rotate to the required horizontal direction via the worm 22 and worm wheel 23.

[0021] Pitch angle: Rotate the handle 19 to adjust the trimmer 16 to the desired pitch angle via the threaded rod 10, connecting block 18 and connecting rod 17.

[0022] Start the operation: Start motor 14 to drive the pruning shears 16 to rotate at high speed. The operator holds the push handle 3 to push the device for precise green pruning. For curved pruning, it can be easily achieved by simply making minor adjustments to the handle 24 or the rotating handle 19 during the pushing process.
