Description

Technical Field

[0001] This utility model relates to the field of shrub maintenance technology, and in particular to a pruning vehicle for shrub maintenance. Background Technology

[0002] In the field of landscaping maintenance, shrub pruning is an important daily task, and the efficiency and precision of pruning vehicles directly affect the quality of maintenance. Traditional shrub pruning equipment generally suffers from problems such as cumbersome operation and poor positioning stability when adjusting the position of pruning tools.

[0003] For example, some equipment relies on manual adjustment, requiring repeated calibration, which is time-consuming and labor-intensive, and is prone to displacement of the pruning position due to vibration, resulting in an uneven shrub pruning surface. On the other hand, equipment using simple mechanical transmission often suffers from defects such as low power transmission efficiency and unreliable position locking due to unreasonable transmission structure design, making it difficult to adapt to the fine pruning needs of shrubs in different locations. Especially in complex terrain or high-frequency operation scenarios, the practicality and reliability of the equipment urgently need to be improved. To address these issues, a shrub maintenance pruning vehicle is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pruning cart for shrub maintenance, which aims to improve the problem of inconvenient adjustment of the pruning tool position in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pruning cart for shrub maintenance includes a mobile cart. A working block is fixedly connected to the outside of the mobile cart. A rotating rod is rotatably connected inside the working block. A drive wheel is fixedly connected to one end of the rotating rod. A rotating wheel is meshed with the outside of the drive wheel. A rotating column is fixedly connected to one end of the rotating wheel. A moving block is rotatably connected to the outside of the rotating column. A pressing rod is slidably connected inside the moving block. A spring is sleeved on the outside of the pressing rod. A locking tooth is fixedly connected to one end of the pressing rod. Multiple fixing teeth are fixedly connected to the outside of the working block. An installation component for easy replacement and installation of pruning tools is fixedly connected inside the moving block. As a further description of the above technical solution: The mounting assembly includes a motor, which is externally fixedly connected to the outside of the movable block. A working column is fixedly connected to the drive end of the motor. Multiple slots are provided inside the working column. A trimmer head is slidably connected inside the working column. Multiple positioning blocks are fixedly connected to the outside of the trimmer head. As a further description of the above technical solution: Rotating the rotating rod controls the rotation of the drive wheel, which in turn drives the rotating wheel to rotate, thereby controlling the rotation of the connected rotating column within the working block; As a further description of the above technical solution: The outer shape of the rotating column is set as a spiral pattern, and the interior of the moving block is opened with spiral pattern holes. Thus, when the rotating column rotates, it drives the moving block to move. At the same time, the moving block is constrained by the working block to prevent it from moving off course. As a further description of the above technical solution: When the pressing rod is pressed, the spring accumulates elastic force. At this time, the locking teeth connected to one end of the pressing rod disengage from the multiple fixed teeth, so that the movement of the moving block is unrestricted. As a further description of the above technical solution: After the moving block is moved to a certain position, the pressure on the pressing rod is released, the spring releases its elastic force, the pressing rod resets, and then the locking teeth re-engage with the fixing teeth, so as to prevent vibration and displacement during operation. As a further description of the above technical solution: The multiple positioning blocks outside the trimmer head are controlled to slide into the working column and rotate along the multiple slots opened inside the working column, thereby quickly engaging with the working column; As a further description of the above technical solution: The motor drive direction is the direction of the engaging end of the trimmer head rotating and engaging in the slot, to prevent unstable disengagement during operation.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the rotating rod drives the component to move the moving block up and down, and the working block is constrained to prevent deviation. The pressing rod disengages the locking teeth from the fixed teeth to adjust the position, and after release, the spring returns to its original position and locks in place. The structure provides stable transmission, is easy to operate, adapts to different positions, and improves accuracy and efficiency.

[0007] 2. In this utility model, the motor is fixed to the moving block and drives the working column. The positioning block of the trimmer head slides into the slot and rotates to engage. The motor drives the working column to rotate the trimmer head. The driving direction enhances engagement, prevents disengagement, and ensures stable operation. Attached Figure Description

[0010] 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.

[0011] Reference Figures 1 to 4 This utility model provides an embodiment of a pruning cart for shrub maintenance, comprising a mobile cart 1, which serves as a basic carrier providing mobility. A working block 2 is fixedly connected to the outside of the mobile cart 1, providing a foundation for installation and support. A rotating rod 3 is rotatably connected inside the working block 2, serving as a power input component that drives the pruning cart through its own rotation. A drive wheel 4 is fixedly connected to one end of the rotating rod 3, enabling power transmission and conversion. A rotating wheel 5 is meshed with the outside of the drive wheel 4, receiving and transmitting the power from the drive wheel 4. One end of the rotating wheel 5 is fixedly connected to a rotating column 6. The rotating column 6 is designed to convert rotational motion. Rotating the rotating rod 3 controls the rotation of the drive wheel 4, which in turn drives the rotating wheel 5 to rotate, thereby controlling the rotation of the connected rotating column 6 within the working block 2. A movable block 7 is rotatably connected to the outside of the rotating column 6. The movable block 7 is designed to move under the drive of the rotating column 6, thereby adjusting the position of the trimming tool. At the same time, it is constrained by the working block 2 to ensure stable movement. The external shape of the rotating column 6 is set as a spiral pattern, and the interior of the movable block 7 has spiral pattern holes. Thus, when the rotating column 6 rotates, it drives the movable block 7 to move. At the same time, the movable block 7 is constrained by the working block 2 to prevent deviation.

[0012] The movable block 7 has a sliding connection to a pressing rod 8, which is designed to unlock or lock the movable block 7. A spring 9 is fitted around the pressing rod 8; this spring 9 accumulates elasticity when the pressing rod 8 is pressed and provides reset force after the pressing is released. A locking tooth 10 is fixedly connected to one end of the pressing rod 8; this locking tooth 10 is fixed to one end of the pressing rod 8 and cooperates with a fixing tooth 11 to lock the position of the movable block 7, preventing it from shifting due to vibration during operation. The working block 2 has multiple fixing teeth 11 fixedly connected to its exterior; these fixing teeth 11 are designed to fix the working block 2 to its exterior. The moving block 7 has multiple locking points that engage with the locking teeth 10 to adapt to different trimming positions and enhance the stability of the moving block 7. When the pressing rod 8 is pressed, the spring 9 accumulates elastic force. At this time, the locking teeth 10 connected to one end of the pressing rod 8 disengages from the multiple fixed teeth 11, allowing the moving block 7 to move freely. When the moving position of the moving block 7 is controlled, the pressing rod 8 is released, the spring 9 releases its elastic force, the pressing rod 8 resets, and then the locking teeth 10 re-engage with the fixed teeth 11, preventing vibration and displacement during operation. The moving block 7 has an internal fixed connection with a mounting component that facilitates the replacement and installation of trimming tools.

[0013] Reference Figure 1 , Figure 5 The installation components include a motor 16, which is designed to provide rotational power. The motor 16 is externally fixedly connected to the outside of the moving block 7. The drive end of the motor 16 is fixedly connected to a working column 12, which is designed to perform the dual functions of power transmission and installation positioning. The working column 12 has multiple slots 13 inside, which are designed to provide installation guidance and positioning. A pruning shear head 14 is slidably connected inside the working column 12, which is designed to complete the pruning action by rotating and cutting shrub branches.

[0014] The trimmer head 14 is externally fixed with multiple positioning blocks 15. The positioning blocks 15 are designed here to transmit torque and prevent the trimmer head from disengaging during trimming. The multiple positioning blocks 15 on the outside of the trimmer head 14 slide into the working column 12 along the multiple slots 13 opened inside the working column 12 and rotate, thereby quickly engaging with the working column 12. The motor 16 drives the trimmer head 14 in the direction of the engaging end of the rotation and engagement within the slots 13, preventing instability and disengagement during operation.

[0015] Working Principle: The working principle of a shrub maintenance pruning cart's movable pruning tool is as follows: When the position of the pruning tool needs to be adjusted, the operator rotates the rotating rod 3. The rotating rod 3 drives the drive wheel 4 to rotate, and the drive wheel 4 meshes with the rotating wheel 5, thereby driving the rotating wheel 5 to rotate. The rotating column 6 connected to the rotating wheel 5 then rotates within the working block 2. The exterior of the rotating column 6 is decorated with a spiral pattern, and the movable block 7 has spiral pattern holes inside. When the rotating column 6 rotates, the movable block 7 moves up and down along the spiral pattern of the rotating column 6. At the same time, because the movable block 7 is constrained by the working block 2, it can prevent movement deviation, thereby realizing the vertical position adjustment of the pruning tool. Before adjusting the position, the pressing rod 8 needs to be pressed. At this time, the spring 9 accumulates elastic force, and the locking teeth 10 at one end of the pressing rod 8 disengages from the multiple fixed teeth 11 on the exterior of the working block 2, so that the movable block 7 can move freely. Once the movable block 7 has moved to the desired position, the pressure on the pressing rod 8 is released, the spring 9 releases its elasticity, the pressing rod 8 resets, and the locking teeth 10 and fixed teeth 11 re-engage, thus fixing the movable block 7 and preventing positional displacement due to vibration during operation. This structure achieves stable power transmission, allowing the rotating column 6 to rotate smoothly, thereby driving the movable block 7 to move precisely. The design of the spiral pattern and spiral pattern holes converts the rotational motion of the rotating column 6 into the linear motion of the movable block 7, resulting in high transmission efficiency and smooth movement. The engagement structure of the locking teeth 10 and fixed teeth 11 can lock the movable block 7 in multiple positions, adapting to the needs of shrub pruning in different locations. Once locked, it offers strong stability, effectively reducing vibration displacement during operation and improving pruning accuracy and efficiency. The spring 9 provides power for the reset of the locking teeth 10, making it more convenient and effortless for operators to adjust the position. The entire process is simple and reliable, enhancing the practicality and convenience of the pruning cart.

[0016] The working principle of the mounting assembly is as follows: Motor 16 is fixed to the outside of moving block 7, and its drive end is fixedly connected to working column 12. When installing trimmer head 14, multiple positioning blocks 15 on its outside are aligned with multiple slots 13 inside working column 12 and slid in. Then, trimmer head 14 is rotated to engage and fix the positioning blocks 15 with the slots 13. During operation, motor 16 starts, driving working column 12 to rotate. Through the cooperation of slots 13 and positioning blocks 15, trimmer head 14 rotates synchronously to complete the trimming operation. Because the driving direction of motor 16 is the direction of engagement between trimmer head 14 and working column 12, the engagement force between positioning blocks 15 and slots 13 is enhanced during rotation, effectively preventing trimmer head 14 from disengaging due to vibration or other reasons during operation, ensuring stable operation.

[0017] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
