Description

Technical Field

[0001] This utility model relates to the field of garden tools, and more specifically to a contour-following lawn mower. Background Technology

[0002] In existing technology, a lawn mower is a mechanical device used for trimming lawns and clearing weeds, widely used in landscaping, agriculture, road maintenance, and other fields. It can efficiently clear weeds in various terrains, maintain a clean landscape, reduce the breeding of pests and diseases, ensure traffic visibility and driving safety, and prevent soil erosion. Using a lawn mower can significantly improve work efficiency, save a lot of labor costs, reduce the labor intensity and injury risk of operators, and also has the advantages of being easy to operate and highly adaptable.

[0003] Traditional lawn mowers, with their slicing or other cutting components, can only cut the plane where their drive wheels are located. When faced with complex terrain and vegetation of different heights, the mowing effect is not good and it is difficult to meet the needs of fine mowing. Moreover, the lawn mower often needs to be pushed by hand or loaded on a vehicle and driven by a person. In large-area, complex terrain mowing tasks, a lot of time and manpower are required.

[0004] Therefore, how to provide a new type of conformal mower that can be operated remotely and adaptable to mowing in complex terrain is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a conformal grass cutter, which aims to solve the technical problem that the cutting surface of the above-mentioned traditional grass cutter is difficult to adapt to complex terrain due to the influence of its structure.

[0006] A contour-following lawn mower includes:

[0007] The frame has tracked walking mechanisms installed on both sides.

[0008] The head-mounted grass-cutting mechanism includes a mounting plate, a steering assembly, a servo motor, and a cutting blade. The mounting plate is rotatably connected to the front end of the frame about the front-rear direction of the frame. The steering assembly is mounted on the upper surface of the mounting plate. The fixed end of the servo motor is fixedly connected to the mounting plate. The cutting blade is located below the mounting plate and is connected to the power output end of the servo motor.

[0009] The tail-end grass-cutting mechanism includes a second mounting plate, a first conformal wheel, a second servo motor, and a second cutting blade. The second mounting plate is connected to the rear end of the frame in a lifting and lowering manner along the height of the frame and is rotatably connected about the front-rear direction of the frame. The two first conformal wheels are rotatably connected to both sides of the second mounting plate. The fixed end of the second servo motor is fixedly connected to the second mounting plate. The second cutting blade is located below the second mounting plate and is connected to the power output end of the second servo motor.

[0010] Through the above technical solution, this utility model rotatably connects the head mowing mechanism and the tail mowing mechanism at the front and rear ends of the frame, respectively. This allows the head mowing mechanism and the tail mowing mechanism to be unrestricted by the plane on which the frame is located and to perform adaptive mowing on the plane on which it is located. First, the head mowing mechanism performs preliminary mowing of the weeds in front of the frame, and then the tail mowing mechanism, which can be raised and lowered along the height of the frame, performs secondary mowing. This can adapt to complex terrain and mow more thoroughly. The tracked walking mechanism enables the mower to move stably and flexibly on complex terrain. It has the characteristics of being suitable for complex terrain, secondary mowing, and strong driving ability.

[0011] Preferably, it also includes a slider and a slide rail. The slider is fastened to the rear end of the frame, and the slide rail is slidably connected to the slider along the height direction of the frame. A rotating column is fixedly connected to the slide rail on the opposite surface of the mounting plate two. A rotating hole is provided on the mounting plate two, which is arranged and rotatably connected to the rotating column.

[0012] Preferably, the conformal wheel includes a triangular plate and rollers, and the mounting plate has support columns fixedly connected to both sides. The center of the triangular plate is rotatably connected to the support column, and the three rollers are rotatably connected to the three tips of the triangular plate.

[0013] Preferably, the three sides of the triangular plate are concave, and there are two of them, which are symmetrically arranged on both sides of the roller.

[0014] Preferably, the number of tail hay trimming mechanisms is two, and they are arranged symmetrically on both sides of the frame.

[0015] Preferably, the steering assembly includes a T-shaped rod, a conformal wheel 2, a transmission bar, and a servo motor 3. One end of the crossbar of the T-shaped rod is rotatably connected to the upper surface of the mounting plate 1, and the other end is rotatably connected to the conformal wheel 2. The end of the vertical rod of the T-shaped rod is slidably and rotatably connected to the end of the transmission bar. The transmission bar is slidably connected to the upper surface of the mounting plate 1 along the side of the frame. The fixed end of the servo motor 3 is fixedly connected to the mounting plate 1. The power output end of the servo motor 3 is fastened with a gear. The upper surface of the transmission bar has teeth that are arranged and connected to the gear.

[0016] Preferably, a guide post is fixedly connected to the end of the transmission bar, and an elongated hole is opened at the end of the vertical T-shaped rod. The guide post and the elongated hole are slidably and rotatably connected.

[0017] Preferably, there are two conformal ground wheels and two T-shaped rods, which are symmetrically arranged at the center of the mounting plate along the side of the frame.

[0018] Preferably, it also includes a power control box, which integrates a battery and a controller. The battery is wired to the controller, and the controller is electrically connected to the drive module of the track walking mechanism, servo motor one, servo motor two, and servo motor three.

[0019] Preferably, the controller integrates wireless transmission and reception modules.

[0020] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a conformal lawn mower with the following beneficial effects: First, the head-mounted mowing mechanism performs initial trimming, and then the tail-mounted mowing mechanism, combined with the lifting function, performs secondary trimming, which can clean up any missed or incompletely trimmed weeds, making the trimming more thorough and improving the quality. The tracked walking mechanism enhances the stability and passability of the lawn mower on complex terrain, enabling it to move stably and flexibly on different surfaces such as lawns, mud, and sand, reducing slippage and jamming, and ensuring work efficiency.

Detailed Implementation

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] See appendix Figure 1-6 This utility model discloses a conformal grass cutter, including: a frame 1, a head grass cutting mechanism 3 and a tail grass cutting mechanism 4;

[0030] Tracked walking mechanisms 2 are installed on both sides of the frame 1;

[0031] The head-mounted grass-cutting mechanism 3 includes a mounting plate 31, a steering assembly 32, a servo motor 33, and a cutting blade 34. The mounting plate 31 is rotatably connected to the front end of the frame 1 about the front-rear direction of the frame 1. The steering assembly 32 is mounted on the upper surface of the mounting plate 31. The fixed end of the servo motor 33 is fixedly connected to the mounting plate 31. The cutting blade 34 is located below the mounting plate 31 and is connected to the power output end of the servo motor 33.

[0032] The tail-end grass-cutting mechanism 4 includes a second mounting plate 41, a first conformal wheel 42, a second servo motor 43, and a second cutting blade 44. The second mounting plate 41 is connected to the rear end of the frame 1 in a vertical direction along the height of the frame 1 and is rotatably connected about the front-back direction of the frame 1. The two first conformal wheels 42 are rotatably connected to both sides of the second mounting plate 41. The fixed end of the second servo motor 43 is fixedly connected to the second mounting plate 41. The second cutting blade 44 is located below the second mounting plate 41 and is connected to the power output end of the second servo motor 43.

[0033] Specifically, the two tracked walking mechanisms 2 on both sides of the frame 1 are driven by two drive motors, and the speed of the tracked walking mechanisms 2 on both sides is adaptively adjusted while the grass cutting mechanism 3 at the head turns.

[0034] In some embodiments, the system further includes a slider 6 and a slide rail 5. The slider 6 is fastened to the rear end of the frame 1, and the slide rail 5 is slidably connected to the slider 6 along the height direction of the frame 1. A rotating column is fixedly connected to the opposite surface of the slide rail 5 and the mounting plate 41. The mounting plate 41 has a rotating hole that is correspondingly arranged and rotatably connected to the rotating column. Thus, the cooperation of the slider 6 and the slide rail 5 provides a stable lifting guide for the mounting plate 41, making its movement along the height direction of the frame 1 more stable and accurate. This ensures smooth height adjustment and precise positioning of the tail-end grass-cutting mechanism 4, thereby better adapting to different vegetation and terrain changes.

[0035] Specifically, a rotating plate 11 is fixedly connected to the front end of the frame 1 along the height direction. The rotating plate 11 has a second rotating hole along the front-rear direction of the frame 1. A connecting plate 36 is fixedly connected to the rear end of the mounting plate 31 along the direction perpendicular to the plate surface of the mounting plate 31. A rotating shaft 35, which is arranged and rotatably connected to the second rotating hole, is fixedly connected to the opposite surface of the connecting plate 36 and the rotating plate 11.

[0036] In other embodiments, the conformal wheel 42 includes a triangular plate 421 and rollers 422. Support columns are fixedly connected to both sides of the mounting plate 41. The center of the triangular plate 421 is rotatably connected to the support columns, and three rollers 422 are rotatably connected to the three apexes of the triangular plate 421. Thus, the ability of the tail-end mowing mechanism 4 to overcome obstacles during operation can be improved by the triangular arrangement of the three rollers 422 on the conformal wheel 42.

[0037] Specifically, support blocks 45 are fixedly connected to both sides of the mounting plate 2 41. Support columns are fixedly connected to the support blocks 45 along the side of the frame 1. A connecting block 46 is fixedly connected to the front end of the mounting plate 2 41. A rotating hole is provided in the connecting block 46 along the front-back direction of the frame 1.

[0038] In one embodiment, the three sides of the triangular plate 421 are concave, there are two of them, and they are symmetrically arranged on both sides of the roller 422.

[0039] In one embodiment, there are two tail mowing mechanisms 4, which are arranged symmetrically on both sides of the frame 1. This increases the mowing range of the mower by increasing the number of mechanisms, allowing the mower to fit more closely to the ground. The two tail mowing mechanisms 4 can adapt to different ground features respectively.

[0040] In some embodiments, the steering assembly 32 includes a T-shaped rod 321, a conformal wheel 322, a transmission plate 323, and a servo motor 324. One end of the crossbar of the T-shaped rod 321 is rotatably connected to the upper surface of the mounting plate 31, and the other end is rotatably connected to the conformal wheel 322. The end of the vertical rod of the T-shaped rod 321 is slidably and rotatably connected to the end of the transmission plate 323. The transmission plate 323 is slidably connected to the upper surface of the mounting plate 31 along the side of the frame 1. The fixed end of the servo motor 324 is fixedly connected to the mounting plate 31. A gear 325 is fastened to the power output end of the servo motor 324. The upper surface of the transmission plate 323 has teeth 3231 that are arranged and connected to the gear 325.

[0041] Specifically, the structure of the conformal ground wheel 2 322 is the same as that of the conformal ground wheel 1 42.

[0042] Specifically, a support block 37 is fixedly connected to the upper surface of the mounting plate 31. A sliding groove is provided on the upper surface of the support block 37 along the side of the frame 1, and the transmission bar plate 323 is slidably connected to the sliding groove.

[0043] In some embodiments, a guide post 326 is fixedly connected to the end of the transmission bar 323, and an elongated hole 3211 is opened at the end of the vertical rod of the T-shaped rod 321. The guide post 326 is slidably and rotatably connected to the elongated hole 3211.

[0044] In this embodiment, there are two conformal ground wheels 322 and two T-shaped rods 321, which are symmetrically arranged along the center of the mounting plate 31 on the side of the frame 1.

[0045] In some specific embodiments, a power control box 7 is also included. The power control box 7 integrates a battery and a controller. The battery is wired to the controller, and the controller is electrically connected to the drive module of the tracked walking mechanism 2, servo motor 33, servo motor 43, and servo motor 324. Thus, the power control box 7 integrates the battery and controller, achieving centralized power supply and control system management, facilitating management and maintenance. The battery provides unified power to all components, ensuring the lawnmower can operate continuously and stably without an external power source. The controller centrally controls the actions of each actuator, improving control efficiency and accuracy, and enabling coordinated operation of all mechanisms.

[0046] In this embodiment, the controller integrates a wireless transmitter and receiver module. Therefore, the controller, with its integrated wireless transmitter and receiver module, can receive remote control signals and control the lawnmower, eliminating the need for operators to be physically present on-site. This reduces labor intensity and safety risks, making it particularly suitable for lawnmower operations in large areas or dangerous terrain, thus improving work efficiency and operational flexibility.

[0047] Specifically, this also includes remote control, which connects to the controller via wireless signals.

[0048] The specific principle of the conformal lawn mower provided in this embodiment is as follows:

[0049] The front and rear ends of the frame 1 are respectively rotatably connected to the head weeding mechanism 3 and the tail weeding mechanism 4, so that the head weeding mechanism 3 and the tail weeding mechanism 4 are not limited by the plane on which the frame 1 is located and can perform adaptive trimming according to the plane on which it is located. First, the head weeding mechanism 3 performs preliminary trimming of the weeds in front of the frame 1, and then the tail weeding mechanism 4, which can be raised and lowered along the height direction of the frame 1, performs secondary trimming. It can adapt to complex terrain and trim more thoroughly.
