[0029] like Figures 1-5 As shown in the figure, this utility model embodiment provides a lawnmower.
[0030] A lawnmower includes a frame 1, a lifting mechanism 2, a track mechanism 3, and blades 4. Gear motors 5 are installed on both rear ends of the frame 1, and the output ends of the gear motors 5 are connected to the track mechanism 3. The lifting mechanism 2 is located in the middle of the frame 1 and is connected to a connecting plate 6. A drive motor 7 is installed on the connecting plate 6, and the output end of the drive motor 7 passes through the connecting plate 6 and is connected to the blades 4. Universal wheels 8 are installed on both front ends of the frame 1.
[0031] This invention uses a geared motor 5 instead of a traditional gasoline engine as the drive source, significantly reducing noise and vibration levels during operation and improving user comfort. Since the internal combustion engine is eliminated, the lawnmower no longer produces exhaust emissions, meeting modern environmental protection requirements and reducing environmental impact. The lifting mechanism 2 allows for precise adjustment of the blade height, adapting to different lawn conditions and ensuring a smooth and aesthetically pleasing lawn surface. Because the two side track mechanisms 3 are driven by two geared motors 5 respectively, the lawnmower can be steered during operation by controlling the different speeds of the two track mechanisms 3 and coordinating with the casters 8, effectively saving motor resources and energy consumption.
[0032] This embodiment of a lawnmower includes a lifting mechanism 2 comprising two electric push rods 9 and two connecting rods 10. Lifting frames 11 are provided on both sides of the top of the frame 1. The two electric push rods 9 are respectively mounted on the two lifting frames 11 and are horizontally placed. The upper and lower ends of the connecting rods 10 are respectively connected to the output end of the electric push rods 9 and the top of the connecting plate 6. The middle part of the connecting rod 10 is rotatably connected to the frame 1. Specifically, the lifting mechanism 2 uses electric push rods 9 in conjunction with connecting rods 10 to achieve precise control of the blade height 4. The horizontal placement of the lifting frames 11 and electric push rods 9 ensures smoother force transmission during adjustment. The electric push rods 9 drive the connecting rods 10 to rotate, causing the lower end of the connecting rods 10 to swing, thereby driving the connecting plate 6 to rise and fall.
[0033] It is understood that the connecting rod 10 is L-shaped, and the corner of the connecting rod 10 is rotatably connected to the frame 1.
[0034] In this embodiment of the lawnmower, the output end of each electric push rod 9 is provided with a connector 12, and the bottom of each connector 12 is connected to a horizontal crossbar 13. Both the front and rear ends of the horizontal crossbar 13 are rotatably connected to the connecting rod 10. Specifically, the bottom of the connector 12 is connected to the horizontal crossbar 13, and the connecting rod 10 is rotatably connected. This design increases the system's flexibility and response speed, enabling the lawnmower to maintain good operating performance under different working conditions, while also enhancing the reliability of the connections between various components.
[0035] The lawnmower described in this embodiment has fixed seats 14 on both sides of the frame 1, and a long shaft 15 is provided between the two fixed seats 14. Both connecting rods 10 are rotatably connected to the long shaft 15. Specifically, the design of the long shaft 15 and the fixed seats 14 simplifies the connection between the connecting rods 10 and the frame 1, reduces assembly steps, and lowers the failure rate. At the same time, this design facilitates daily inspection and maintenance, extending the service life of the equipment.
[0036] It is understood that in this utility model, there are four connecting rods 10 and two long shafts 15.
[0037] In this embodiment, a lawnmower has an adjusting and fixing sleeve 16 at the front end of the frame 1, and an adjusting rod 17 is connected to the top of the casters 8. The adjusting rod 17 passes through the adjusting and fixing sleeve 16. Specifically, the combination of the adjusting and fixing sleeve 16 and the adjusting rod 17 allows the user to adjust the height of the casters 8 according to actual needs, enabling the lawnmower to better adapt to different ground conditions, such as slopes or uneven ground, thus improving operational flexibility and safety.
[0038] This embodiment of a lawnmower includes a frame 1 with fixed plates 18 on both sides. Each track mechanism 3 includes a track 19, a drive wheel 20, and two drive wheels 21. The output end of a reduction motor 5 is connected to the drive wheel 20, and both drive wheels 21 are rotatably connected to the fixed plates 18. The drive wheel 20 and the two drive wheels 21 are connected via the track 19. Specifically, the track mechanism 3 is driven by the reduction motor 5 through gear transmission to drive the drive wheel 20, which in turn drives the two drive wheels 21 via the track 19, forming a complete transmission chain. This design not only improves power transmission efficiency but also enhances the traction capacity of the track mechanism 3, making it suitable for more types of grassland environments.
[0039] In this embodiment of the lawnmower, the output end of the reduction motor 5 is provided with a first gear 22, and the input end of the drive wheel 20 is provided with a second gear 23.
