Description

Technical Field

[0001] This utility model relates to the field of pruning device technology, and in particular to an improved garden pruning device. Background Technology

[0002] Garden pruning devices are tools or equipment specifically designed for pruning garden plants such as trees, shrubs, and lawns. These devices, through different working principles and designs, make garden pruning more efficient, precise, and convenient. There are many types of garden pruning devices, ranging from manual tools to power tools and automated systems.

[0003] Traditional tools are not convenient for height adjustment, requiring the use of other tools, which is inefficient and dependent on the operator's physical strength. Angle adjustment also needs to be done manually, which is cumbersome and has low precision, making it difficult to meet the needs of complex shapes. Working at heights can easily lead to falls, and individual skill differences exacerbate the fluctuations in pruning quality. This not only threatens worker safety but also seriously restricts work efficiency and artistic effect. Especially when dealing with tall trees or curved hedges, the limited operation often leads to high rework rates and increased maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an improved garden pruning device.

[0005] This utility model is achieved using the following technical solution: an improved garden pruning device, comprising a base plate, a support leg fixedly connected to the bottom of the base plate, a self-locking caster wheel fixedly connected to the bottom of the support leg, a handle fixedly connected to the left side of the base plate, and further comprising:

[0006] A lifting mechanism, comprising a supporting housing fixedly connected to the top of the base plate, wherein a connecting plate is slidably connected to the right side of the supporting housing;

[0007] An adjustment mechanism, comprising a fixed housing fixedly connected to the front of a connecting plate, and a trimming assembly provided at the bottom of the connecting plate.

[0008] As a further improvement to the above solution, a servo motor is fixedly connected to the top of the supporting shell, a threaded rod is fixedly connected to the output end of the servo motor, and a moving block is connected to the external thread of the threaded rod.

[0009] The above technical solution uses a servo motor to precisely control the rotation speed and direction of the threaded rod, thereby achieving precise lifting and lowering of the moving block. Compared with manual operation, this is more efficient and stable, and the height can be adjusted programmably, improving the level of automation and operational accuracy.

[0010] As a further improvement to the above solution, the movable block is slidably connected inside the supporting shell, the connecting plate is fixedly connected to the right side of the movable block, and a fixing plate is fixedly connected to the right side of the supporting shell.

[0011] The above technical solution clarifies that the moving block slides inside the supporting shell and is fixed to the connecting plate. At the same time, a fixed plate is added as a support point to restrict the movement trajectory of the moving block, prevent deviation or shaking, and ensure that the lifting process is smooth and reliable.

[0012] As a further improvement to the above solution, a limiting post is fixedly connected to the bottom of the fixing plate, the connecting plate is slidably connected to the outside of the limiting post, and the end of the limiting post away from the fixing plate is fixedly connected to the top of the base plate.

[0013] By adding limit posts to the above technical solutions, a linear guiding function is provided for the connecting plate, avoiding tilting or jamming caused by uneven load, ensuring the stability of the vertical lifting of the trimming component, and at the same time sharing the lateral force, reducing wear and improving the mechanical life.

[0014] As a further improvement to the above solution, a drive motor is fixedly connected to the top of the fixed housing, and a worm gear is fixedly connected to the output end of the drive motor, with the worm gear rotatably connected inside the fixed housing.

[0015] The above technical solution utilizes the power of a drive motor to replace manual angle adjustment, reducing labor intensity. The large reduction ratio of the worm gear transmission makes angle adjustment more delicate and controllable, suitable for the fine trimming needs of complex shapes.

[0016] As a further improvement to the above solution, a rotating column is rotatably connected inside the connecting plate, and a worm gear is fixedly connected outside the rotating column, with the worm gear meshing with the worm.

[0017] The above technical solution achieves a self-locking function through the worm gear and worm, preventing accidental external forces from causing angle deviation and ensuring that the trimming angle remains stable over a long period of time, while also taking into account energy saving and efficiency.

[0018] As a further improvement to the above solution, a connecting block is fixedly connected to the outside of the rotating column, and the trimming component is fixedly connected to the bottom of the connecting block.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention uses a servo motor in the lifting mechanism to drive the threaded rod to rotate, which in turn causes the moving block to slide upward along the inside of the supporting shell, thereby pushing the connecting plate to rise synchronously along the limiting post, ultimately achieving height adjustment of the trimming component. This structural design allows operators to quickly and safely adjust the trimming height without the need for external tools, significantly reducing labor intensity and improving work efficiency and safety.

[0021] This invention uses a drive motor within an adjustment mechanism to rotate a worm gear. Through the meshing transmission between the worm wheel and the rotating column, the connecting block is driven to rotate, thereby precisely adjusting the working angle of the pruning component. The transmission method of the worm gear and worm wheel has self-locking and high torque transmission efficiency, ensuring stable and reliable angle positioning. It can flexibly adapt to the pruning needs of green plants of different shapes, improve pruning accuracy and aesthetics, and meet the design requirements of diverse garden shapes.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5An improved garden pruning device according to this embodiment includes a base plate 1, a support leg 11 fixedly connected to the bottom of the base plate 1, a self-locking caster wheel 12 fixedly connected to the bottom of the support leg 11, a handle 13 fixedly connected to the left side of the base plate 1, and further includes:

[0032] The lifting mechanism 2 includes a support housing 201 fixedly connected to the top of the base plate 1, and a connecting plate 205 slidably connected to the right side of the support housing 201.

[0033] The adjustment mechanism 3 includes a fixed housing 301 fixedly connected to the front of the connecting plate 205, and a trimming component 307 is provided at the bottom of the connecting plate 205.

[0034] A servo motor 202 is fixedly connected to the top of the supporting housing 201. A threaded rod 203 is fixedly connected to the output end of the servo motor 202. A moving block 204 is connected to the external thread of the threaded rod 203.

[0035] The movable block 204 is slidably connected inside the supporting shell 201, the connecting plate 205 is fixedly connected to the right side of the movable block 204, and the supporting shell 201 is fixedly connected to the right side of the fixed plate 206.

[0036] The bottom of the fixed plate 206 is fixedly connected to the limiting post 207, the connecting plate 205 is slidably connected to the outside of the limiting post 207, and the end of the limiting post 207 away from the fixed plate 206 is fixedly connected to the top of the base plate 1.

[0037] A drive motor 302 is fixedly connected to the top of the fixed housing 301, and a worm gear 303 is fixedly connected to the output end of the drive motor 302. The worm gear 303 is rotatably connected inside the fixed housing 301.

[0038] The connecting plate 205 is rotatably connected to a rotating column 304, and the rotating column 304 is fixedly connected to a worm gear 305. The worm gear 305 meshes with the worm 303.

[0039] The rotating column 304 is externally fixedly connected to a connecting block 306, and the trimming component 307 is fixedly connected to the bottom of the connecting block 306.

[0040] The implementation principle of the improved garden pruning device in this application embodiment is as follows: When the device is needed for garden pruning, the operator first pushes the handle 13. Since the bottom of the base plate 1 is fixedly connected to the support leg 11, and the bottom of the support leg 11 is equipped with a self-locking universal wheel 12, the entire device can move flexibly and stably to the designated pruning position. After reaching the appropriate position, the servo motor 202 is started. The servo motor 202 serves as a power source, and its output end is firmly fixedly connected to the threaded rod 203. As the servo motor 202 starts to run, it drives the threaded rod 203 to rotate clockwise. At this time, the threaded rod 203 rotates clockwise. The connected movable block 204 will slide and rise along the thread direction inside the support housing 201. Since the connecting plate 205 is fixedly connected to the right side of the movable block 204, the rising action of the movable block 204 will drive the connecting plate 205 to slide and rise together outside the limiting post 207. One end of the limiting post 207 is fixed to the bottom of the fixed plate 206, and the other end is fixed to the top of the base plate 1. It provides precise motion guidance for the connecting plate 205, ensuring that the connecting plate 205 can rise smoothly and vertically. Then, through the connecting plate 205, the entire adjustment mechanism 3 is also driven to rise, and finally the trimming component 307 reaches the appropriate height.

[0041] After the trimming assembly 307 rises to the ideal height, its angle needs to be adjusted to adapt to different trimming needs. At this time, the drive motor 302 is started. The drive motor 302 is installed on the top of the fixed housing 301, and its output end is fixedly connected to the worm gear 303. When the drive motor 302 works, it will drive the worm gear 303 to rotate smoothly inside the fixed housing 301. Since the worm gear 303 and the worm wheel 305 mesh with each other, the rotation of the worm gear 303 will be transmitted to the worm wheel 305, causing the worm wheel 305 to rotate accordingly. The rotating column 304 is fixedly connected inside the worm wheel 305. Therefore, the rotation of the worm wheel 305 will drive the rotating column 304 to rotate synchronously inside the connecting plate 205. The rotating column 304 is also fixedly connected to the outside of the connecting block 306. Thus, the rotation of the rotating column 304 will drive the connecting block 306 to rotate together. Through the connecting block 306, the angle of the trimming assembly 307 can be precisely adjusted.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
