[0029] Refer to Figures 1 to 5As shown in the figure, a special lawn mower for seawall slope protection includes a telescopic rod 1. A microcontroller 27 is fixedly arranged on the outer wall of the telescopic rod 1. The microcontroller 27 is electrically connected to a switch button 28 and a rotary switch 29. It also includes a cutter 2, a mounting shell 3, a rotating shaft 4, a driving component 5, an electric control component 6, a rotating component 7 and two swing arms 8. An installation plate 9 is fixedly arranged at the end of the telescopic rod 1. Two support rods are fixedly arranged on the outer wall of the installation plate 9. The rotating component 7 is arranged on the two support rods. The electric control component 6 is arranged on the installation plate 9. The two swing arms 8 are both fixedly arranged on the rotating component 7. The mounting shell 3 is fixedly arranged at one end of the two swing arms 8 away from the rotating component 7. The driving component 5 is arranged inside the mounting shell 3. The rotating shaft 4 is rotatably arranged on the mounting shell 3, and its bottom end passes through the bottom of the mounting shell 3. The cutter 2 and the bottom end of the rotating shaft 4 are connected through a buffer component 10. A protective shell 30 is fixedly arranged on the outer wall of the installation plate 9. An avoidance groove for the rotation of the two swing arms 8 is arranged on the outer wall of the protective shell 30.
[0030] Refer to Figures 1 to 5 As shown in the figure, the driving component 5 includes a DC motor 11, a first bevel gear 12 and a second bevel gear 13. The DC motor 11 is fixedly arranged inside the mounting shell 3. The first bevel gear 12 is fixedly arranged on its output end. The second bevel gear 13 is fixedly arranged on the rotating shaft 4. The first bevel gear 12 and the second bevel gear 13 are meshed and connected. The DC motor 11 is electrically connected to the controller. When mowing the grass, the worker presses the switch button 28. After the controller receives the signal of the switch button 28, it starts the DC motor 11, so that its output end drives the first bevel gear 12 to be meshed and connected. Since the second bevel gear 13 is fixedly connected to the rotating shaft 4, and the first bevel gear 12 and the second bevel gear 13 are meshed and connected, and the cutter 2 is fixedly connected to the rotating shaft 4 through the buffer component 10, the cutter 2 is driven to rotate, and the weeds on the seawall slope are cut.
[0031] Refer to Figures 1 to 5 As shown in the figure, the electric control component 6 includes a biaxial motor 14 and two first gears 15. The biaxial motor 14 is fixedly arranged on the outer wall of the installation plate 9. The two first gears 15 are respectively fixedly arranged on the two output ends of the biaxial motor 14. The biaxial motor 14 is electrically connected to the controller. The shape of the seawall slope usually includes various types. The cutter 2 must adjust the cutting angle according to the shape of the seawall slope so that the cutter 2 can be close to the slope and cut the weeds on the seawall slope cleanly. In this case, the worker rotates the rotary switch 29. After the controller receives the signal of starting the rotary switch 29, it starts the biaxial motor 14, thereby driving the two first gears 15 to rotate.
[0032] Refer to Figures 1 to 5As shown, the rotating assembly 7 includes a rotating rod 16 and two second gears 17. The rotating rod 16 is rotatably arranged between the ends of the two support rods away from the mounting plate 9. The two second gears 17 are symmetrically arranged at both ends of the rotating rod 16. Each first gear 15 is meshed and connected with a second gear 17. One end of each swing arm 8 away from the mounting shell 3 is fixedly connected to the rotating rod 16. When the two first gears 15 rotate, since the two second gears 17 are fixedly connected to both ends of the rotating rod 16, each first gear 15 is meshed and connected with a second gear 17, and one end of each swing arm 8 away from the mounting shell 3 is fixedly connected to the rotating rod 16. Since each first gear 15 is smaller than a second gear 17, the mounting shell 3 between the two swing arms 8 and the cutter 2 on the mounting shell 3 are driven to rotate slowly. When the cutting angle of the cutter 2 is consistent with the shape of the seawall slope protection, the worker stops rotating the knob switch 29, and then cuts off the power supply of the double-shaft motor 14 through the controller to stop the rotation of the cutter 2, so as to ensure that the cutter 2 will not damage the seawall slope protection when mowing grass, playing a protective effect.
[0033] Refer to Figures 1 to 5 As shown, the buffer assembly 10 includes a buffer plate 18, a limiting plate 19, a plurality of limiting rods 20 and a plurality of buffer springs 21. A connecting shaft 22 is fixedly arranged at the center of the cutter 2. The buffer plate 18 is fixedly arranged at the top of the connecting shaft 22. The plurality of limiting rods 20 are arranged at equal intervals on the top of the buffer plate 18. Each buffer spring 21 is sleeved on the outer wall of a limiting rod 20. The limiting plate 19 is fixedly arranged at the bottom end of the rotating shaft 4. The top of each limiting rod 20 is slidably connected to the limiting plate 19. A retaining ring 23 is fixedly arranged on the outer wall of each limiting rod 20. The bottom of each retaining ring 23 is in contact with the top of the limiting plate 19. When the cutter 2 cuts weeds, sometimes it will accidentally touch the stones on the seawall slope protection. When the cutter 2 touches the stones, the impact force will be transmitted to the buffer plate 18 through the connecting shaft 22. Since the buffer plate 18 is slidably connected to the limiting plate 19 through the plurality of limiting rods 20, and each buffer spring 21 is sleeved on a limiting rod 20, the buffer plate 18 and the plurality of limiting rods 20 will slide up once. During this process, the plurality of buffer springs 21 contract to conduct a buffering, thereby playing a role in protecting the cutter 2 and being beneficial to improving the service life of this lawn mower.
[0034] Refer to Figures 1 to 5 As shown, a strap 24 is fixedly arranged on the outer wall of the telescopic rod 1 in the circumferential direction. The strap 24 facilitates the worker to carry this lawn mower on the back, which is beneficial to reducing the effort required to grasp the telescopic rod 1 during mowing, improving the mowing efficiency, and at the same time facilitating the worker to carry this lawn mower, enhancing the portability of this device.
[0035] Refer to Figures 1 to 5As shown, a grip 25 is fixedly provided on the outer wall in the circumferential direction of the telescopic rod 1. When mowing the grass, when a worker carries the lawn mower on the back, one hand grasps the telescopic rod 1 and the other hand tightly holds the grip 25 to mow the grass on the seawall slope protection, which is convenient for operation and saves effort.
[0036] Refer to Figures 1 to 5 As shown, a dust-proof plate 26 is fixedly provided on the outer wall of the installation shell 3 through a plurality of bolts.
