Description

Technical Field

[0001] This invention relates to the field of greening pruning technology, and more specifically, to a pruning device for roadside greening. Background Technology

[0002] Currently, greening is widely used in urban construction, roadside greening, and highway median strip greening. With the continuous expansion of the types and areas of greening, the workload of garden restoration and maintenance is also increasing. In order to achieve the goal of high-efficiency and high-quality garden maintenance, the current pruning and maintenance methods have transitioned from the initial manual pruning to semi-automatic pruning using power tools and internal combustion engine tools.

[0003] Especially in the pruning of shrubland green belts, shaping is often required. Commonly used shapes are generally flat cuts without curvature. When arched shaping is needed, it can usually only be done manually, which is time-consuming, labor-intensive, and costly. Chinese patent document CN113841528B discloses a damage-prevention pruning system for vine tea planting, including a pruning frame and an adjustment component for adjusting the height of the pruning frame. Several mounting cylinders are installed on the pruning frame, and each mounting cylinder has an electric switch on its side. An inner liner is slidably installed inside each mounting cylinder via an adjustment mechanism, and a DC motor and power supply are installed inside the inner liner. Several electric switches are electrically connected to the same control switch. One end of the inner liner is connected to a sleeve, which passes through the bottom wall of the mounting cylinder and the pruning frame and is connected to a cutting shear. This anti-damage pruning system for vine tea cultivation uses a DC motor to drive the rotation of the second pruning shear, which works in conjunction with the fixed first pruning shear. This allows the two pruning shears to function as scissors, significantly improving the pruning efficiency of vine tea, reducing the time cost for growers, and enabling the pruning of arched structures. The overall structure is simple and highly practical.

[0004] However, the technical solutions disclosed in the aforementioned patents still have at least the following problems:

[0005] 1. In this technical solution, the trimming is accomplished by multiple cutting shears (scissors 1 and 2) working together, which presents the following problems: First, it lacks the planar shapes on both sides of the arch, resulting in a non-standard arch structure, and it cannot achieve a smooth transition from the planar to the curved surface. Second, after trimming by multiple cutting shears (scissors 2), the trimmed surfaces between adjacent cutting shears (scissors 2) actually have included angles, failing to meet the standard for a curved shape. Therefore, the resulting shape is not an arch shape, but rather a quasi-curve shape.

[0006] 2. There are gaps between adjacent cutting shears, so these gaps are not easy to cut during the trimming process, and it is easy to miss them;

[0007] 3. In order to achieve a smooth state that is closest to the arc, this technical solution requires increasing the number of cutting shears one and two and reducing their trimming area in the cross-sectional direction. This will make the structure more complex, increase costs, and increase the load on the arc plate. Summary of the Invention

[0015] In some embodiments of the present invention, the sliding part includes a movable seat, a first roller group and a second roller group. The first roller group includes at least one first roller, and the first rollers are all rotatably disposed on one side of the slide rail.

[0024] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0025] 1. The slide rail on the arched frame in this invention is also an arched structure; therefore, the movement trajectory of the sliding part on the slide rail is arched. After the trimming blade in the trimming assembly is set on the corresponding sliding part, it can also move along an arched trajectory. When the trimming blade moves along this arched trajectory, its trimming surface remains tangent to the arched structure, thus enabling the trimming of a smooth arch. On the vertical surfaces on both sides of the arch, the trimming surface of the trimming blade is actually parallel to the vertical surface, thus enabling the trimming of a standard arched shape. Therefore, this invention can efficiently trim a smooth-transitioning standard arched shape, replacing manual labor and improving the trimming effect.

[0027] 3. In this invention, the trimming blades move along the axis of the arched frame under the drive of the moving platform. Multiple trimming blades slide sequentially in a pre-existing time order, driven by their respective sliding parts, and perform trimming work. During this process, the actual movement trajectory of the trimming blades is a spiral trajectory. Therefore, using multiple trimming blades allows for supplementary trimming of untrimmed areas along the moving direction of the platform. Thus, a smooth trimming effect can be achieved with fewer trimming blades, further avoiding trimming omissions. Furthermore, this invention does not require increasing the number of trimming blades or reducing their trimming area in the cross-sectional direction to improve trimming smoothness. Therefore, the structure of this invention is relatively simple, reducing costs and the load-bearing burden on the arched frame. Attached Figure Description

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0041] Example

[0042] Please refer to Figures 1-9 This embodiment provides a pruning device for roadside greening, including a mobile platform, an arched frame 1, multiple sliding components, and multiple pruning components. The arched frame 1 is disposed on the mobile platform and can cover the green plant belt. Each sliding component includes a slide rail 2 and a sliding part. The slide rail 2 is an arched structure adapted to the arched frame 1, and the slide rail 2 is arranged along the arched extension direction of the arched frame 1. The sliding part is slidably disposed on the slide rail 2, and adjacent slide rails 2 are parallel to each other. Each pruning component includes a pruning blade and a first driving mechanism. The pruning blades are correspondingly disposed on the sliding parts, and the pruning blades are located inside the arched frame 1. The first driving mechanism is connected to its corresponding pruning blade and is used to drive the pruning blade to perform pruning operations.

[0043] The slide rail 2 on the arched frame 1 is also an arched structure; therefore, the movement trajectory of the sliding part on the slide rail 2 is arched. After the trimming blade in the trimming assembly is placed on the corresponding sliding part, it can also move along an arched trajectory. When the trimming blade moves along this arched trajectory, its trimming surface remains tangent to the arched structure, thus producing a smooth arch. On the vertical surfaces on both sides of the arch, the trimming surface of the trimming blade is actually parallel to the vertical surface, thus producing a standard arched shape. Therefore, this invention can efficiently replace manual trimming to produce a smooth-transitioning standard arched shape, improving the trimming effect.

[0044] During the trimming process, the trimming blade moves along the tangent direction of the arch frame 1. Therefore, there will be no gap between adjacent trimming blades on the arch surface during the cutting process, thus avoiding the problem of omissions during the trimming process.

[0045] It is worth noting that the aforementioned trimming blades move along the axis of the arched frame 1 under the drive of the moving platform. Multiple trimming blades slide sequentially in a chronological order, driven by their respective sliding parts, and perform trimming work. During this process, the actual movement trajectory of the trimming blades is a spiral trajectory. Therefore, using multiple trimming blades allows for supplementary trimming of untrimmed areas along the moving platform's direction. Thus, a smooth trimming effect can be achieved with fewer trimming blades, further preventing trimming omissions. Furthermore, this invention does not require increasing the number of trimming blades or reducing their trimming area in the cross-sectional direction to improve trimming smoothness. Therefore, the structure of this invention is relatively simple, reducing costs and the load-bearing burden on the arched frame 1.

[0046] Specifically, during the pruning process, the pruning blade that prioritizes pruning first moves along a straight segment of slide rail 2 with the sliding part, pruning the side of the green plant belt based on a predetermined arched side, creating an inclined straight channel. When the pruning blade enters the arc segment of slide rail 2, it creates a spiral channel, and finally enters another straight segment of slide rail 2, forming another inclined straight channel. This process is repeated, and the aforementioned straight channels and spiral channels form a spiral trajectory for pruning. The spiral trajectories created by multiple pruning blades are spliced ​​together to form the predetermined arched pruning amount. When a pruning blade begins pruning, moving from one end of the guide rail to the other, the displacement distance of the pruning blade in the direction of movement of the moving platform is 'a'; the center distance between this pruning blade and the adjacent pruning blade is 'b', and the distance between two adjacent pruning blades is 'c', which must satisfy 2a ≥ c ≥ 2a - b. Specifically, in this embodiment, the actual value of c is 2a - b. c. Within the above range, the remaining trimming tools can sequentially trim the remaining untrimmed areas within a displacement distance a, until all untrimmed areas within that range are trimmed.

[0047] It should be further explained that the time d is used for the trimming cutter to move from one end of the guide rail to the other. Therefore, at every time interval d, the trimming cutter on the same side is driven from the starting point of the slide rail 2 by the corresponding sliding part and slides towards the other end of the slide rail 2. During this sliding, the trimming cutter is already driven by the first drive mechanism and performing the trimming work. This avoids gaps between adjacent spiral trajectories, preventing omissions during trimming.

[0048] Please refer to Figures 1-8 In some embodiments of this example, the sliding part includes a movable base 3, a first set of rollers 4, and a second set of rollers 5. The first set of rollers 4 includes at least one first roller 4, which is rotatably disposed on one side of the slide rail 2. The second set of rollers 5 includes at least one second roller 5, which is rotatably disposed on the side of the slide rail 2 away from the first rollers 4. Both the first rollers 4 and the second rollers 5 are rotatably disposed on the movable base 3, and the trimming tool is disposed on the movable base 3. During the sliding process, the movable base 3 makes rolling contact with both sides of the slide rail 2 through the first set of rollers 4 and the second set of rollers 5, thereby ensuring the stability and smoothness of the movable base 3's movement on the slide rail 2. Since the first set of rollers 4 and the second set of rollers 5 are respectively located on different sides of the slide rail 2 and are both rotatably mounted on the movable seat 3, when the movable seat 3 moves on the slide rail 2, the first rollers 4 and the second rollers 5 can simultaneously bear the weight of the movable seat 3 and the trimming blade on it, and evenly distribute the weight onto the slide rail 2, avoiding deformation or damage to the slide rail 2 due to excessive local stress. At the same time, the aforementioned sliding mechanism also allows the trimming blade to maintain a stable trimming height and angle during the trimming process, thereby improving trimming quality and efficiency.

[0049] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 Specifically, in this embodiment, the first roller group 4 includes two first rollers 4, and the second roller group 5 includes two second rollers 5. The two first rollers 4 and the two second rollers 5 are sequentially connected to form a rectangle. Thus, when the distance between the first roller 4 and its corresponding second roller 5 is the same as the distance of the slide rail 2, it ensures that the sliding part can smoothly transition from linear movement to arc movement on the slide rail 2, guaranteeing that the sliding part can move smoothly on the slide rail 2.

[0050] Please refer to Figures 2-7 In this embodiment, the trimming tool includes a tool body 6 and a connecting rod 7. One end of the connecting rod 7 is connected to the tool body 6, and the other end is connected to the movable seat 3. The axial direction of the connecting rod 7 is perpendicular to the tangential direction of the arch frame 1. The perpendicularity of the axial direction of the connecting rod 7 to the tangential direction of the arch frame 1 ensures that the trimming tool always trims in the tangential direction of the arch frame 1.

[0051] Furthermore, the aforementioned connecting rod 7 is a telescopic rod structure. The telescopic rod structure of the connecting rod 7 allows for adjustment of the distance between the trimming blade and the arched frame 1 as needed, thereby adjusting the trimming size of the arch. It should be noted that the aforementioned telescopic rod has a self-locking structure, which is existing technology and will not be further described here. After the telescopic rod is self-locked, it will no longer extend or retract.

[0052] Please refer to Figures 1-7 Furthermore, the aforementioned cutter body 6 is a disc cutter. The first drive mechanism includes a first drive motor 8, which is mounted on the movable base 3. The connecting rod 7 includes a telescopic section 701 and a fixed section 702. The first drive motor 8 is connected to one end of the fixed section 702 to drive the fixed section 702 to rotate. One end of the telescopic section 701 is coaxially connected to the disc cutter, and the other end is coaxially and detachably connected to the free end of the fixed section 702. In actual use, the first drive motor 8 starts, driving the fixed section 702 to rotate. Since the telescopic section 701 is coaxially and detachably connected to the fixed section 702, and the other end of the telescopic section 701 is coaxially connected to the disc cutter, the disc cutter rotates, thus realizing the trimming action. Moreover, this detachable connection method facilitates the replacement and maintenance of the disc cutter. When the disc cutter is worn or damaged, it can be easily and quickly removed and replaced with a new disc cutter, ensuring the normal use of the trimming device. The aforementioned telescopic section 701 can be adjusted in length according to actual pruning needs to adapt to greening pruning work in different locations and of different sizes.

[0053] Please refer to Figure 1 and Figure 6 Specifically, the aforementioned slide rail 2 is located on the outer side of the arched frame 1. The arched frame 1 has a groove 9 parallel to the guide rail, and the fixed section 702 passes through the groove 9 and can move freely along the extension direction of the groove 9. The groove 9 is actually designed to prevent the arched frame 1 from affecting the normal movement of the fixed section 702 with the movable seat 3. Specifically, in this embodiment, the movable seat 3 is always tangent to the arched frame 1 (this tangency refers not only to the arc-shaped section of the slide rail 2 but also to its parallelism to the arched frame during the straight section of the slide rail 2).

[0054] Please refer to Figure 1 and Figure 6 Furthermore, a limiting post structure is slidably installed within the aforementioned slide groove 9. This limiting post structure can slide freely along the slide groove 9, and the fixed section 702 is connected to the limiting post. One end of the limiting post structure is connected to the fixed section 702. Through this connection, when the fixed section 702 moves within the slide groove 9, the limiting post structure provides stability and guidance, preventing the fixed section 702 from shifting during movement, and further ensuring that the disc cutter can perform trimming work according to the predetermined trajectory. Simultaneously, in some special cases, the limiting post structure can also act as a buffer, reducing the collision between the fixed section 702 and the inner wall of the slide groove 9, and extending the service life of the device.

[0055] Please refer to Figure 3 and Figure 5It should be noted that each sliding component in this embodiment includes two slide rails 2, which are arranged parallel and symmetrically on both sides of the slide groove 9. Each slide rail 2 is provided with a corresponding first roller 4 and a second roller 5, which are rolled on it. The first rollers 4 on the two slide rails 2 are coaxially aligned and connected by a first rotating shaft 14. Similarly, the second rollers 5 on the two slide rails 2 are coaxially aligned and connected by a second rotating shaft 15. Each of the first rotating shaft 14 or the second rotating shaft 15 is connected to a second driving mechanism, which includes a second driving motor 13. The second driving motor 13 is connected to the first rotating shaft 14 or the second rotating shaft 15 and is used to drive the first rotating shaft 14 or the second rotating shaft 15 to rotate. Thus, the corresponding first roller 4 or second roller 5 can be driven to roll on the slide rail 2.

[0056] In order to achieve the above-mentioned "every interval time d", the corresponding sliding part moves the trimming blade located on the same side from the starting point of the slide rail 2 and performs trimming work. The first drive motor 8 and the second drive motor 13 are connected to a control unit, which can precisely control the operation of the first drive motor 8 and the second drive motor 13.

[0057] The aforementioned control unit is an integrated circuit chip. It is a small but complete microcomputer system that integrates a central processing unit (CPU) with data processing capabilities, random access memory (RAM), read-only memory (ROM), multiple I / O ports and interrupt system, timer / counter and other functions (and may also include display driver circuit, pulse width modulation circuit, analog multiplexer, A / D converter and other circuits) onto a single silicon chip using very large-scale integrated circuit technology. It is widely used in the field of industrial control.

[0058] Preferably, the aforementioned limiting post structure is a guide post coupling 10, which is used to detachably connect the fixed section 702 and the telescopic section 701. The guide post coupling 10 has high coaxiality and precision, ensuring the stability and accuracy of the connection between the fixed section 702 and the telescopic section 701. It also has good wear resistance and corrosion resistance, enabling it to operate normally in various harsh environments. Furthermore, the guide post coupling 10 is easy to install and disassemble, allowing for quick maintenance or replacement of the fixed section 702 and the telescopic section 701, thus improving work efficiency. Simultaneously, the guide post coupling 10 can withstand certain radial and axial forces, further enhancing the reliability of the entire trimming device.

[0059] Please refer to Figure 8In some application scenarios of this embodiment, the aforementioned mobile platform includes an extension arm 11 and a mobile vehicle 12. One end of the extension arm 11 is connected to the mobile vehicle 12, and the other end is connected to the arched frame 1. The mobile vehicle 12 provides mobility for the entire pruning device, allowing it to flexibly adjust its working position according to the location of the green area, greatly improving the coverage and efficiency of the pruning work. The extension arm 11 serves as a connection and support, not only firmly fixing the arched frame 1 at a suitable height and position so that the disc cutter can accurately prune the green plants, but also withstanding various forces generated by the arched frame 1 and the disc cutter during operation, ensuring the stability and reliability of the entire pruning device during operation. Furthermore, the length of the extension arm 11 can be adjusted according to actual needs to meet the pruning requirements of green plants of different heights and ranges.

[0060] Please refer to Figure 9 In other application scenarios of this embodiment, the mobile platform includes two mobile chassis 16, which are respectively disposed at the ends of both sides of the arched frame 1. A synchronous lifting mechanism is provided between any mobile chassis 16 and the arched frame 1. The synchronous lifting mechanism ensures that the two mobile chassis 16 remain synchronized during the lifting process, thereby ensuring that the arched frame 1 is always in a horizontal state. This helps the disc cutter to perform uniform and precise pruning of the green plants. The two mobile chassis 16 can drive the two sides of the arched frame 1 to move synchronously, setting the arched frame 1 on the green plant belt. After the green plant belt to be pruned is located inside the arched frame 1, the mobile chassis 16 are driven to move, which can drive the pruning blades to perform pruning work.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
