Abstract
Description
Technical Field
[0001] This utility model relates to the field of lawn mowers, and more specifically to a lawn mower. Background Technology
[0002] Golf demands extremely high-quality turf, with the green being of paramount importance. To protect the turf, a green ring is installed at the edge of the green, with a height higher than the inner turf, as a transition. When mowing, it's crucial to avoid touching the green ring, as the height difference can damage it. Because the green is circular, the edges near the green ring can be difficult to reach during mowing, necessitating a circular mowing motion along the inner edge of the green ring. However, accurately judging the width of the green ring visually is challenging, and variations in operator skill can lead to inconsistent ring widths, potentially damaging the green ring turf.

[0006] When the positioning rod is installed in the horizontal mounting position, the positioning rod extends horizontally, and the visual guide extends to the side area of the body and is adapted to be aligned with the target object;
[0007] When the positioning rod is installed in the vertical mounting position, the positioning rod extends vertically, and the visual guide is located in the area above the body.
[0008] In some embodiments, the fixing component includes a first fixing rod and a second fixing rod, the first fixing rod extending horizontally along the width direction of the body to form the horizontal mounting position, and the second fixing rod extending vertically along the height direction of the body to form the vertical mounting position.
[0009] In some embodiments, the first fixing rod and the second fixing rod are independently disposed at different positions on the body, wherein the first fixing rod is installed on the left and / or right edge of the body, and the second fixing rod is installed on the rear support structure of the body.
[0010] In some embodiments, the first fixing rod and the second fixing rod are fixedly connected to form a fixing bracket, and the fixing bracket is fixedly mounted on the machine body.
[0011] In some embodiments, the second fixing rod is vertically connected to the axial center of the first fixing rod, and both ends of the first fixing rod form the horizontal mounting position.
[0012] In some embodiments, the fixing component includes a movable rod that is rotatably mounted to the body via a rotating structure. The axis of the rotating rod is perpendicular to the horizontal plane of travel of the body, and rotating the movable rod locks it in the horizontal mounting position or the vertical mounting position.
[0013] In some embodiments, a fitting is also included, the fitting being adapted to securely connect the fixing component and the end of the positioning rod.
[0014] In some embodiments, the visual guide includes a connector and a counterweight, the connector being adapted to connect the end of the positioning rod away from the machine body to the counterweight.
[0015] When the positioning rod is installed horizontally, the counterweight block drives the connector to unfold orthogonally relative to the positioning rod under the action of gravity.
[0016] In some embodiments, a quick-release locking element is also included. When the positioning rod is installed vertically, the quick-release locking element is adapted to fix the positioning rod and the counterweight or the connecting member to constrain the radial relative movement of the counterweight and the positioning rod.
[0017] In some embodiments, the visual guidance unit includes an indicator sign fixedly mounted to the end of a positioning rod and perpendicular to the positioning rod; when the positioning rod is installed horizontally, the outline of the end of the indicator sign is collinearly aligned with the target object; when the positioning rod is installed vertically, the indicator sign forms a spatial flag.
[0018] Compared with the prior art, the lawn mower provided by this utility model has at least one of the following beneficial effects:
[0019] 1. A positioning rod is installed on the side of the green mower using a fixing component. One end of the rod is fixed to the mower, and the other end has a visual guide close to the ground. During operation, the visual guide extends to the side of the machine body, aligns with the edge of the green, and moves along the edge to guide the mower to operate within the specified range, ensuring that the width of the green ring is consistent. After mowing, the positioning rod can be vertically fixed to the mower, and the visual guide is located above the machine body, without hindering its normal movement.
[0020] 2. The first fixing rod extends horizontally along the width of the machine body, thereby creating a stable horizontal mounting position; the second fixing rod extends vertically along the height of the machine body, thereby forming a reliable vertical mounting position; the first fixing rod and the second fixing rod are fixedly connected to form a stable fixed bracket, which is fixed to the machine body as a whole. This not only makes full use of the space structure of the machine body, but also effectively improves the stability and reliability of the positioning rod installation.
[0021] 3. One end of the connector is flexibly connected to the end of the positioning rod away from the machine body, and the other end is tightly fixed to the counterweight. Under the action of gravity, the counterweight automatically sinks and drives the connector to be orthogonally extended relative to the positioning rod. When the lawnmower is operating on an uneven green, this flexible connection method can automatically adapt to the terrain changes and always maintain the relatively stable posture of the connector and the ground, thereby achieving a precise visual guidance function.
[0022] 4. The visual guidance unit is a sign.

[0033] refer to Figure 1 and Figure 2This utility model provides a lawn mower, including a body 1 and a positioning device 2. The body 1 is equipped with a mowing device and a walking device. The positioning device 2 includes a fixing component 21 and a positioning rod 22. The fixing component 21 is adapted to be installed on the body 1 and has a horizontal mounting position 211 and a vertical mounting position 212. One end of the positioning rod 22 is adapted to be installed in the vertical mounting position 212 or the horizontal mounting position 211, and the other end is provided with a visual guide part 23. When the positioning rod 22 is installed in the horizontal mounting position 211, the positioning rod 22 extends horizontally, and the visual guide part 23 extends to the side area of the body 1 and is adapted to be aligned with the target object. When the positioning rod 22 is installed in the vertical mounting position 212, the positioning rod 22 extends vertically, and the visual guide part 23 is located in the upper area of the body 1.
[0034] In this embodiment, a positioning rod 22 is installed on the side of the green mower via a fixing component 21. One end of the rod is fixed to the mower, and the other end is provided with a visual guide 23 close to the ground. During operation, the visual guide 23 extends to the side of the machine body 1, aligns with the edge of the green, and moves along the edge to guide the mower to operate within a specified range, ensuring that the width of the green ring is consistent. After mowing, the positioning rod 22 can be vertically fixed to the mower, and the visual guide 23 is located above the machine body 1, without hindering its normal movement.
[0035] Specifically, the machine body 1 is equipped with a high-efficiency mowing device that can easily trim lawns, and a convenient walking device that facilitates movement on the lawn. The two work together to ensure the mower can move efficiently and stably across the lawn and complete the mowing task. A pusher is also located at the rear of the machine body 1 for propelling it. The positioning device 2 consists of a fixing component 21 and a positioning rod 22. The fixing component 21 is easy to install on the machine body 1 and has a vertical mounting position 212 and a horizontal mounting position 211. One end of the positioning rod 22 can be flexibly installed in either the vertical or horizontal mounting position 211 as needed, while the other end is equipped with a visual guide 23. When one end of the positioning rod 22 is installed in the horizontal mounting position 211, the entire positioning rod 22 is horizontal. The visual guide 23 at the other end is delicate and conspicuous, located on one side of the machine body 1, facilitating precise alignment with the target object and providing accurate positioning guidance for the mower, ensuring uniform mowing operations. Furthermore, when the positioning rod 22 is installed in the vertical mounting position 212, it stands firmly upright. The visual guide 23 is then positioned on top of the machine body 1, acting like a directional marker, providing operators with a more intuitive orientation reference. This greatly enhances the lawnmower's applicability and ease of operation in different environments. The positioning rod 22 and the visual guide 23 enable the lawnmower to operate efficiently in various terrains and scenarios, becoming a powerful assistant for gardeners.
[0036] The system also includes fittings suitable for securing the fixing assembly 21 and the end of the positioning rod 22 to ensure the positioning rod 22 remains stable and secure during operation. This application does not further limit the form of the fittings. Fittings include, but are not limited to, threaded fittings, snap-fit fittings, elastic fittings, wedge-shaped fittings, magnetic fittings, etc., wherein threaded fittings include nuts and bolts: the bolt passes through the connecting hole at the end of the fixing assembly 21 and the positioning rod 22, and then the nut is tightened, securing both through the friction and preload of the threads. These are all prior art in the field and will not be further elaborated upon in this application. Of course, the connection between the positioning rod 22 and the fixing assembly 21 can also be achieved through an interference fit, where the diameters of the first and second fixing rods are slightly smaller than the inner diameter of the positioning rod 22, allowing the positioning rod 22 to be fitted into and locked in place by the first fixing rod.
[0037] It is worth noting that this application effectively solves the problems of traditional lawnmowers lacking a travel positioning device 2, having unstable travel trajectories, and having mowing quality overly dependent on the operator's skill level by adding a positioning device 2 to the lawnmower. This positioning device 2 can precisely fix the travel trajectory of the lawnmower, significantly improving mowing quality and consistently ensuring lawn quality. The focus of this application is on the installation of the positioning rod 22 with the horizontal mounting position 211 and the vertical mounting position 212 on the fixing component 21. When the positioning rod 22 is installed in the horizontal mounting position 211, it extends horizontally, allowing the visual guide 23 to extend to the side area of the machine body 1, accurately aligning with the target object. When operating on the green, the positioning rod 22 is installed in the horizontal mounting position 211 on the side, with one end fixed to the lawnmower and the visual guide 23 at the other end close to the ground. During operation, the visual guide 23 extends to the side of the machine body 1, closely aligning with the edge of the green, effectively guiding the lawnmower along the edge of the green. This ensures that the mowing operation is carried out within the specified range, thereby guaranteeing the consistency of the green ring width and resulting in a neat and aesthetically pleasing lawn after mowing. After the mowing operation is completed, the positioning rod 22 can be vertically fixed to the vertical mounting position 212 of the lawnmower. At this time, the visual guide 23 is located in the area above the machine body 1, which does not hinder the normal movement of the lawnmower or other subsequent operations, greatly improving the practicality and convenience of the lawnmower.
[0038] Furthermore, the fixing component 21 includes a first fixing rod and a second fixing rod. The first fixing rod extends horizontally along the width direction of the body 1 to form a horizontal mounting position 211, and the second fixing rod extends vertically along the height direction of the body 1 to form a vertical mounting position 212.
[0039] In this embodiment, the first fixing rod extends horizontally along the width direction of the body 1, thereby constructing a stable horizontal mounting position 211; the second fixing rod extends vertically along the height direction of the body 1, thereby forming a reliable vertical mounting position 212.
[0040] Specifically, the first and second fixing rods are independently positioned at different locations on the body 1. The first fixing rod is installed on the left and / or right edge of the body 1, preferably at the suspension point of the grass collection hopper. The second fixing rod is installed on the rear support structure of the body 1, preferably at the rear bracket. The first fixing rod's placement on the left and / or right edge of the body 1 ensures precise horizontal support and fixation for the positioning rod 22 during lawnmower operation, guaranteeing the stability and reliability of the positioning rod 22 in a horizontal working state, and ensuring accurate alignment of the lawnmower along the edge of the target object. The second fixing rod's installation on the rear support structure of the body 1 fully considers the balance and stress distribution of the overall lawnmower structure. When the positioning rod 22 needs to be fixed vertically, the second fixing rod can firmly support the positioning rod 22, so that its visual guide part 23 is located in the area above the machine body 1. This does not hinder the normal movement of the lawnmower, and can also ensure the stability of the positioning rod 22 in the non-working state, avoiding adverse effects on the lawnmower caused by the shaking or loosening of the positioning rod 22.
[0041] It is worth noting that the first and second fixing rods are independently set in different positions on the machine body 1, without interfering with each other and working together to provide a solid foundation for the flexible switching and precise installation of the positioning rod 22, greatly improving the adaptability and convenience of the lawnmower in different operating stages.
[0042] In a modified embodiment, the first fixing rod and the second fixing rod are fixedly connected to form a fixed bracket, and the fixed bracket is fixedly mounted on the body 1.
[0043] In this embodiment, the first fixing rod and the second fixing rod are fixedly connected to form a stable fixed bracket. The fixed bracket is fixed to the body 1 as a whole. This not only makes full use of the spatial structure of the body 1, but also effectively improves the stability and reliability of the positioning rod 22 installation.
[0044] Specifically, the first and second fixing rods are no longer independently installed, but are connected to form a stable fixed bracket, allowing the bracket to be securely installed as a whole at a specific position on the machine body 1. The fixed bracket is fixedly located at the rear of the machine body 1. In practical applications, when the positioning rod 22 needs to be installed in the horizontal mounting position 211 or the vertical mounting position 212, the fixed bracket provides more stable support. At the same time, this integrated fixed bracket simplifies the installation process, reduces the risk of loosening or damage that may result from connecting multiple independent components, and further enhances the stability and durability of the lawnmower during operation.
[0045] Preferably, the second fixing rod is vertically connected to the axial center of the first fixing rod, and both ends of the first fixing rod form horizontal mounting positions 211. In this embodiment, the second fixing rod is vertically connected to the axial center of the first fixing rod, and both ends of the first fixing rod form horizontal mounting positions 211. This not only enhances the overall stability of the fixing assembly 21, but also improves the flexibility and symmetry of the positioning rod 22 during installation, enabling the lawnmower to maintain good balance and alignment in different operating modes.
[0046] Furthermore, the fixed assembly 21 includes a movable rod, which is rotatably mounted on the body 1 via a rotating structure. The axis of the rotating rod is perpendicular to the horizontal plane of travel of the body 1. Rotating the movable rod locks it in a horizontal mounting position 211 or a vertical mounting position 212.
[0047] In this embodiment, by rotating the movable rod, it can be flexibly switched between different working states and firmly locked in the horizontal installation position 211 or the vertical installation position 212, meeting diverse operational needs and effectively improving the adaptability and practicality of the lawnmower.
[0048] Specifically, the movable rod is rotatably mounted to the machine body 1 via a rotating structure, making the operation of the fixed component 21 more convenient and flexible. The axis of the rotating rod is perpendicular to the horizontal plane of the machine body 1, ensuring stability and accuracy during rotation. The end of the movable rod away from the rotating structure forms a horizontal mounting position 211 and a vertical mounting position 212, further enhancing its functionality and symmetry, ensuring stable installation of the positioning rod 22 in both horizontal and vertical mounting states, providing strong support for the precise operation of the lawnmower. It is worth noting that the rotating structure includes, but is not limited to, a rotating shaft, a worm gear, a gear rack, a universal joint, etc., and this application does not further limit it, as long as it can realize the rotation of the positioning rod 22. A locking structure can also be provided to fix the positioning rod 22 in a horizontal or vertical state to prevent it from shaking.
[0049] Furthermore, the visual guidance unit 23 includes a connector and a counterweight. The connector is adapted to connect the end of the positioning rod 22 away from the body 1 and the counterweight. When the positioning rod 22 is installed horizontally, the counterweight drives the connector to be orthogonally extended relative to the positioning rod 22 under the action of gravity.
[0050] In this embodiment, one end of the connector is flexibly connected to the end of the positioning rod 22 away from the machine body 1, and the other end is tightly fixed to the counterweight. The counterweight automatically sinks under the action of gravity and drives the connector to be orthogonally extended relative to the positioning rod 22. When the lawnmower is working on an uneven green, this flexible connection method can automatically adapt to the terrain changes and always maintain the relatively stable posture of the connector and the ground, thereby achieving a precise visual guidance function.
[0051] Specifically, the connector is preferably a high-strength nylon rope, which has good wear resistance and impact resistance, and can adapt to complex outdoor working environments. One end of the nylon rope is connected to the end of the positioning rod 22 away from the machine body 1 through a metal buckle or mounting hole, ensuring reliable connection. The other end of the nylon rope is firmly fixed to the counterweight. When the positioning rod 22 is installed horizontally, the counterweight hangs naturally under gravity. Due to the flexibility and elasticity of the nylon rope, it will cause the counterweight to swing downwards, ultimately making the connector (nylon rope) and the positioning rod 22 orthogonally deployed. This provides precise visual guidance for the lawnmower during operation, ensuring that the lawnmower operates along the edge of the lawn or a specific target object. The length of the nylon rope can be adjusted according to actual operating needs. By changing the rope length, the distance between the counterweight and the positioning rod 22 can be flexibly controlled, thereby achieving adaptive guidance for lawn edges of different widths and shapes.
[0052] In detail, the positioning rod 22 is a cylindrical tubular structure with a small hole in the front wall for connecting to the connector of the visual guide unit 23. The positioning rod 22 is 900mm long, 20mm outer diameter, and 16mm inner diameter. Its front end is flattened into a square shape with a 5mm diameter hole drilled in the center for connecting to the connector of the visual guide unit 23. The connector is composed of a 12-strand braided high-strength nylon rope with a diameter of 5mm. One end is inserted into the tube for fixation, and the other end is connected and fixed to the front end of the positioning rod 22. The total length of the nylon rope and the counterweight is 300mm. The counterweight is a cylindrical tubular structure, closed at one end and open at the other, 40mm long, 8mm outer diameter, and 5mm inner diameter. It is made of rubber and weighs no less than 10 grams to ensure that it will not easily shake under machine vibration, wind, or other external forces, thus affecting positioning accuracy. If it falls off, it will not damage the cutting tool. The fixing component 21 is made of steel, cylindrical, solid, 100mm long, and 15mm in diameter. The first fixing rod is fixed to the left and right sides of the lawnmower's grass collection bucket suspension frame. During operation, the positioning rod 22 can be inserted into the first fixing device and locked. Connecting the rear end of the positioning rod 22 to the first fixing component, the counterweight block naturally becomes vertical under gravity, with its tip coinciding horizontally with the edge of the lawn. At this time, the distance between the lawn edge and the lawnmower's working area is 750mm, consistent with the target width of the putting green ring, meeting the working requirements. During lawnmower operation, by consistently maintaining the tip of the counterweight block aligned with the lawn edge, a 750mm wide ring can be formed between the lawn edge and the lawnmower's working area, solving the problem of inconsistent ring widths and damage to the putting green ring during mowing, significantly improving the mowing effect and the overall quality of the lawn. The second fixing rod is fixed to the rear support of the lawnmower. In the non-working state, the positioning rod 22 can be inserted into the second fixing device and locked. The positioning device 2 is vertically fixed to the rear of the lawnmower, without affecting the lawnmower's movement or transport.
[0053] Preferably, the device also includes a quick-release locking component. When the positioning rod 22 is installed vertically, the quick-release locking component is suitable for fixing the positioning rod 22 and the counterweight or connector, and is used to constrain the radial relative movement between the counterweight and the positioning rod 22. In this embodiment, the quick-release locking component can effectively constrain the radial relative movement between the counterweight and the positioning rod 22. When the lawnmower is installed vertically with the positioning rod 22 in operation, it prevents the counterweight from shaking due to vibration or other external forces, thus improving the stability of the overall structure. The quick-release locking component can be selected according to the shape of the connector, and this application does not impose further limitations. The quick-release locking component can be a self-locking nut, which has a nylon ring inside to provide good self-locking performance. The positioning rod 22 and the counterweight (or connector) are respectively provided with matching threaded holes. The outer surface of the self-locking nut is designed with a hexagonal head or wing head for easy manual operation, so as to facilitate quick installation and disassembly. The quick-release locking component can also be a strip to fix the positioning rod 22 and the connector.
[0054] In a modified embodiment, the connector can also be a universal joint and a connecting rod. One end of the connecting rod is provided with a visual guide 23, and the other end is rotatably connected to the positioning rod 22 via the universal joint. When the positioning rod 22 is installed horizontally, the counterweight naturally hangs down under the action of gravity, causing the connecting rod to swing downward. Due to the flexibility of the universal joint, the connecting rod can automatically adjust its angle to be orthogonally extended with the positioning rod 22, providing precise visual guidance for the lawnmower operation. Therefore, the form of the connector is similar to the structure of the rotating structure, and this application does not further limit it here.
[0055] Furthermore, the visual guidance unit 23 includes an indicator sign, which is fixedly installed at the end of the positioning rod 22 and perpendicular to the positioning rod 22; when the positioning rod 22 is installed horizontally, the outline of the end of the indicator sign is collinearly aligned with the target object; when the positioning rod 22 is installed vertically, the indicator sign forms a spatial flag.
[0056] In this embodiment, the visual guidance unit 23 is an indicator sign. When the positioning rod 22 is installed horizontally, the end outline of the indicator sign can be aligned with the edge of the lawn or the edge of other target objects, providing a clear visual reference for the lawnmower operator and ensuring that the lawnmower operates along the predetermined route, maintaining the neatness and consistency of the mowing area. When the positioning rod 22 is installed vertically, the indicator sign acts as a flag in space, providing clear directional guidance for the operation of the lawnmower.
[0057] Specifically, the visual guidance unit 23 is an indicator sign, which is fixedly installed at the end of the positioning rod 22 and perpendicular to the positioning rod 22, providing intuitive visual guidance for the operation of the lawnmower. When the positioning rod 22 is installed horizontally, the outline of the end of the indicator sign is collinearly aligned with the target object. Specifically, the outline of the end of the indicator sign can be aligned with the edge of the lawn or the edge of other target objects, providing a clear visual reference for the lawnmower operator, ensuring that the lawnmower operates along a predetermined route, and maintaining the neatness and consistency of the mowing area. For example, when mowing a putting green, the operator can align the outline of the end of the indicator sign with the edge of the putting green and mow along the direction of the indicator sign, thereby ensuring a consistent width of the putting green ring and improving the aesthetics of the lawn.
[0058] When the positioning rod 22 is installed vertically, the indicator sign forms a spatial flag. At this time, the indicator sign acts as a flag in space, providing clear directional guidance for lawnmower operation. Operators can quickly determine the lawnmower's working range and direction by observing the position and direction of the indicator sign from a certain distance, facilitating remote control or adjustment of the working path. This spatial flag design is particularly useful for lawnmowers operating on large lawns or complex terrain. For example, when mowing the lawns of large golf courses or orchards, operators can quickly determine the lawnmower's position and working direction by observing the position of the indicator sign, improving work efficiency and ensuring the comprehensiveness and accuracy of the mowing operation. Simultaneously, this indicator sign design is also easy to install and maintain, allowing for quick disassembly, replacement, or adjustment to adapt to different operational needs and environmental conditions.
[0059] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
