Description

Technical Field

[0001] This utility model relates to the field of garden trimming equipment technology, and in particular to a garden trimming device for urban and rural planning landscapes. Background Technology

[0002] Urban and rural planning is a general term encompassing urban system planning, city planning, town planning, township planning, and village planning. It also requires the planning of the landscape gardens surrounding urban and rural areas. The overall aesthetics of the landscape gardens are improved by altering the terrain, arranging garden paths, and pruning green plants. Pruning devices are needed in landscape garden planning to repair green plants.

[0003] However, in practical use, the existing cutting devices still have the following technical problems:

[0004] Most existing devices cannot be folded, making it difficult to flexibly change the length and angle when pruning taller plants. Workers often need to use ladders and other auxiliary tools, which is not only dangerous but also makes it difficult to find a comfortable operating posture, resulting in low work efficiency and unsatisfactory pruning results. For example, when pruning tall street trees in cities, traditional devices are difficult to achieve the ideal pruning height and angle, affecting the shape of the trees and the overall landscape harmony. Furthermore, when pruning at special angles, workers hold the device for a long time, with their arms bearing the weight of the device and the reaction force of operation, which easily leads to fatigue, hand tremors, and difficulty in ensuring the accuracy of the pruning angle.

[0005] In response to this technical problem, this application proposes a landscape garden trimming device for urban and rural planning. Utility Model Content

Detailed Implementation

[0027] 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.

[0028] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a landscape garden trimming device for urban and rural planning, comprising a support rod 1, with a rotating seat 2 fixedly connected to both the front and rear sides of the support rod 1. A fixed seat 3 is installed on the inner side of each rotating seat 2. Positioning holes 4 are provided on both the left and right sides of the inner wall of the rotating seat 2. A sliding groove 10 is provided inside the fixed seat 3. A slider 5 is slidably connected to both ends of the inner wall of the sliding groove 10. A sliding rod 6 is fixedly connected to the middle of the outer side of each slider 5. The sliding rod 6 passes through both sides of the fixed seat 3 and the outer side of the rotating seat 2. A positioning bolt 7 is fixedly connected to the outer side of each slider 5, and the positioning bolt 7 slides against the inner wall of the positioning hole 4. The connection is as follows: a limiting rod 8 is fixedly connected to the middle of the side of the slider 5, and a spring 9 is installed on the outside of the limiting rod 8; a housing 11 is fixedly connected to the front side of the front fixed seat 3; a through groove 16 is opened on the front side of the inner wall of the housing 11; an outer shell 17 is fixedly connected to the outer side of the housing 11; a motor 12 is fixedly connected to the top side of the inner wall of the housing 11; the motor 12 is connected to the movable plate 14 through the transmission assembly 13; the movable plate 14 passes through the through groove 16 and is slidably connected to the inner wall of the outer shell 17; a serration 15 is fixedly connected to the right side of the movable plate 14; and a rear seat 19 is fixedly connected to the rear side of the rear fixed seat 3.

[0029] Specifically, by sliding the slider 5, the position of the positioning bolt 7 in different positioning holes 4 can be adjusted, thereby achieving flexible adjustment of the angle between the fixed seat 3 and the rotating seat 2. This allows operators to adapt to different garden trimming angle requirements. The operator presses the slider 6 inward, causing the slider 5 to move and disengage the positioning bolt 7 from the current positioning hole 4. After adjusting the angle, the slider 6 is released, and under the action of the spring 9, the slider 5 returns to its original position, and the positioning bolt 7 is inserted into the new positioning hole 4 to complete the fixation. A limit rod 8 is fixedly connected to the middle end of the slider 5 on the side closest to it. A spring 9 is installed on the outside of the limit rod 8. The spring 9 plays a role in resetting and buffering, preventing excessive movement of the slider 5 during angle adjustment. At the same time, when subjected to external impact, the elastic deformation of the spring 9 can buffer the impact and protect the internal structure of the device. The front mounting base 3 is fixedly connected to the front of the housing 11. The front of the inner wall of the housing 11 is provided with a through groove 16. The outer shell 17 is fixedly connected to the outer side of the housing 11. The top of the inner wall of the housing 11 is fixedly connected to the motor 12. The motor 12 is connected to the movable plate 14 through the transmission assembly 13. After the motor 12 is started, it drives the transmission assembly 13 to rotate. Its working principle is that the motor 12 drives the turntable 1301 to rotate. The connecting rod 1302, which is rotatably connected to the bottom edge of the turntable 1301, makes a circular motion with the rotation of the turntable 1301, thereby pushing the movable plate 14 to make a reciprocating linear motion in the through groove 16. This transmission method can stably and efficiently convert the rotational motion of the motor 12 into the linear motion of the movable plate 14.

[0030] Both the front and rear sections of the device are foldable. This design addresses the difficulty of trimming the tops of taller plants when the grip position remains unchanged due to height limitations. The folding structure allows for flexible adjustment of the device's overall length and angle, enabling operators to stand in a comfortable position and trim the tops of taller plants. This significantly expands the device's applicability and enhances its ability to trim garden plants of varying heights.

[0031] Reference Figure 3 , Figure 4 and Figure 5The rear seat 19 has a second sliding groove 22 on its rear side. A limiting groove 23 is formed at the lower end of the inner wall of the second sliding groove 22. The limiting groove 23 is connected to a sliding block 24. Rollers 27 are installed at the four rear corners of the sliding block 25. The limiting block 24 is fixed to the rear seat 19 by a locking assembly 26. The transmission assembly 13 includes a turntable 1301, which is fixedly connected to the bottom of the motor 12. A connecting rod 1302 is rotatably connected to the bottom edge of the turntable 1301. The front end of the connecting rod 1302 is rotatably connected to the rear end of the movable plate 14. The locking assembly 26 includes a screw hole 2601 and a through hole 2602. The screw hole 2601 is formed in the limiting groove 23. At the rear right side of the position block 24, a through hole 2602 is opened at the rear end of the outer wall of the rear seat 19. The screw hole 2601 is connected to the through hole 2602 by a bolt 2603. The bolt 2603 passes through the through hole 2602 and is connected to the screw hole 2601. The left end of the bolt 2603 is threaded to the inner wall of the screw hole 2601. The slide rod 6 passes through the rotating seat 2 and is slidably connected. The left and right ends of the spring 9 are fixedly connected to the side of the slider 5. The top right side of the outer shell 17 is fixedly connected to a second serration 18. A first serration 15 passes through the right side of the outer shell 17. The front top of the rear seat 19 is fixedly connected to a handle 20. The left side of the outer wall of the rear seat 19 is fixedly connected to a handle 21.

[0032] Specifically, the slide 25 can slide stably within the slide groove 22. The function of the roller 27 is that when cutting at a special angle, prolonged holding of the device by the operator can easily lead to angle deviation or arm pain, affecting the cutting work. The roller 27 can transfer some of the support force to the ground, and the operator only needs to guide the device to move appropriately, greatly reducing the burden on the arm, ensuring the accuracy of the angle during the cutting process, and improving work efficiency and cutting quality. The limiting block 24 is fixed to the rear seat 19 through the locking component 26, which includes a screw hole 2601. The through hole 2602 and the screw hole 2601 are opened at the rear right side of the limit block 24. The through hole 2602 is opened at the rear end of the outer wall of the rear seat 19. The screw hole 2601 is connected to the through hole 2602 by a bolt 2603. The bolt 2603 passes through the through hole 2602 and is connected to the screw hole 2601. The left end of the bolt 2603 is threaded to the inner wall of the screw hole 2601. This design of the locking component 26 allows the operator to flexibly adjust and fix the relative position between the slide block 25 and the rear seat 19 by tightening or loosening the bolt 2603 according to actual needs.

[0033] Working principle: During operation, the operator first moves the slider 5 by pressing the slide bar 6, adjusting the position of the positioning bolt 7 in the positioning hole 4 to adjust the angle between the fixed seat 3 and the rotating seat 2. Then, the motor 12 starts, driving the turntable 1301 to rotate. Through the connecting rod 1302, the movable plate 14 is pushed to make reciprocating linear motion in the through groove 16, so that the saw teeth 15 and 18 cooperate to cut. When there is a need to cut the top of the plant, the folding structure of the front and rear parts can be used to adjust the overall length and angle of the device. When cutting at a special angle, the slide 25 slides in the second slide groove 22, and the roller 27 transfers part of the support force to the ground to reduce the burden on the arm. The operator can also adjust the relative position of the slide 25 and the rear seat 19 by tightening or loosening the bolt 2603 with the help of the locking component 26. At the same time, the spring 9 plays a role in reset and buffering, protecting the internal structure of the device.

[0034] 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.
