DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0020] Embodiment: A lawn maintenance device, such as Figure 1-Figure 4 As shown, it includes a vehicle body 1, a moving wheel 2, a water tank 3, a water inlet pipe 31, a water delivery pipe 32, a water pump 4, a nozzle 5, an electric slide rail 6, a fixed block 7 and a piercing roller 8. The moving wheel 2 is installed at the lower part of the vehicle body 1. The moving wheel 2 is an electric wheel. The left part of the vehicle body 1 is connected to the water tank 3. The upper side of the water tank 3 is penetrated by a water inlet pipe 31. The left side of the water tank 3 is penetrated by a water delivery pipe 32. The left part of the water tank 3 is equipped with a water pump 4 through a fixing part. The left side of the water tank 3 is connected to the nozzle 5. The nozzle 5 is connected to the water tank 3 through the water delivery pipe 32. The right part of the vehicle body 1 is symmetrically equipped with electric The slide rail 6 and the electric slide rail 6 are both connected to fixed blocks 7 in a sliding manner up and down, and the piercing rollers 8 are rotatably connected between the fixed blocks 7. When the electric slide rail 6 is started, the electric slide rail 6 drives the fixed blocks 7 and the piercing rollers 8 to move downward, so that the holes on the piercing rollers 8 are pierced into the lawn. Then the moving wheel 2 is operated to move the device. At this time, the piercing rollers 8 will roll with the movement of the device, thereby crushing and punching holes in the lawn. At the same time, the moving wheel 2 and the water pump 4 are started. The water pump 4 draws the maintenance fertilizer liquid from the water tank 3 through the water pipe 32, and evenly sprays it on the lawn that has been punched through the nozzle 5.

[0021] like Figure 1 、 Figure 3 and Figure 4 As shown, it also includes a first protective ring 9 and a second protective ring 10. The first protective ring 9 is connected to the side of the vehicle body 1 close to the puncturing roller 8; the second protective ring 10 is slidably connected to the inside of the first protective ring 9.

[0022] like Figure 1-Figure 4As shown, it also includes a connecting spring 11, a connecting block 12, a servo motor 13, a winding wheel 14 and a pull rope 15. The second protective ring 10 is connected to the first protective ring 9 with a connecting spring 11 through a spring seat. The second protective ring 10 is connected to the connecting block 12. The servo motor 13 is installed on the side of the vehicle body 1 close to the first protective ring 9 through a fixing member. The output shaft of the servo motor 13 is connected to the winding wheel 14 through a coupling. A pull rope 15 is wound around the winding wheel 14. The end of the pull rope 15 that is not connected to the servo motor 13 is connected to the connecting spring 11. The connecting block 12 is connected, and the initial state of the pull rope 15 is taut, driving the servo motor 13. The output shaft of the servo motor 13 will drive the winding wheel 14 to rotate, and the pull rope 15 will stretch accordingly. As the pull rope 15 stretches, the connecting block 12 loses its tension, and the second protective ring 10 rotates downward due to its own weight. The connecting spring 11 is stretched, and the second protective ring 10 will gradually cover the piercing roller 8. When the connecting block 12 reaches the downward limit position on the first protective ring 9, it means that the second protective ring 10 has completed full coverage of the piercing roller 8.

[0023] like Figure 3-Figure 4 As shown, it also includes a start button 16. The start button 16 is connected to the electric slide rail 6. The start button 16 is electrically connected to the servo motor 13. The electric slide rail 6 drives the fixed block 7 and the piercing roller 8 on the fixed block 7 to move upward. When the fixed block 7 touches and presses the start button 16, the servo motor 13 is started, so that the servo motor 13 can be started when the fixed block 7 rises, and then the fixed block 7 and the servo motor 13 are linked, thereby increasing the degree of automation of the device.

[0024] When the device is to be used, first add the maintenance fertilizer liquid into the water tank 3 through the water inlet pipe 31 on the water tank 3, then move the device to the place of use through the moving wheel 2, start the electric slide 6, and the electric slide 6 drives the fixed block 7 and the piercing roller 8 to move downward, and adjust the depth of the holes on the piercing roller 8 into the lawn according to actual needs. Then, operate the moving wheel 2 to move the device. At this time, the piercing roller 8 will roll with the movement of the device, thereby crushing and punching holes in the lawn. At the same time, start the moving wheel 2 and the water pump 4. The water pump 4 draws the maintenance fertilizer liquid from the water tank 3 through the water pipe 32, and sprays it evenly on the lawn that has been punched through the nozzle 5, thereby promoting the lawn to absorb the fertilizer, realizing the simultaneous fertilization and punching, and effectively improving the efficiency of lawn maintenance.

[0025] After use, the electric slide rail 6 is started, and the electric slide rail 6 drives the fixed block 7 and the piercing roller 8 on the fixed block 7 to move upward. When the fixed block 7 touches and presses the start button 16, the servo motor 13 is started, and the output shaft of the servo motor 13 will drive the winding wheel 14 to rotate, and the pull rope 15 will stretch accordingly. As the pull rope 15 stretches, the connecting block 12 loses tension, and the second protective ring 10 rotates downward due to its own weight. The connecting spring 11 is stretched, and the second protective ring 10 will gradually cover the piercing roller 8. When the connecting block 12 reaches the downward limit position on the first protective ring 9, it means that the second protective ring 10 has completed the full coverage of the piercing roller 8, preventing accidental injury during storage of the device, thereby improving the equipment. Safety: Before using again, start the servo motor 13 again, and the output shaft drives the winding wheel 14 to rotate in the opposite direction, and reel in the pull rope 15. During this process, the connecting block 12 is pulled upward, driving the second protective ring 10 to return to its original position, and the connecting spring 11 is reset together. When the connecting block 12 reaches the upper limit position, turn off the motor to ensure that the piercing roller 8 is fully exposed. For subsequent work, repeat the above-mentioned usage process. Except for manually adding the curing fertilizer liquid to the water tank 3, the rest of the operations can be completed automatically by the device, which significantly improves the automation level of the equipment and saves labor costs. In addition, by adding water to the water tank 3, the device can also perform watering tasks, further enhancing the versatility and utilization rate of the equipment.

[0026] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
