[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-3 A lawn mower designed to prevent damage from stones includes a mower body 1, a stone-blocking assembly 2 installed at the front of the mower body 1, and a feed-pushing assembly 3 installed at the front of the stone-blocking assembly 2.

[0024] See Figure 2 Furthermore, the stone-blocking assembly 2 includes an adjusting seat 4, which is fixedly installed at the front of the trimmer body 1. A lifting plate 5 is movably installed inside the adjusting seat 4. Several stone-blocking plates 6 are fixedly installed at the bottom of the lifting plate 5. An adjusting rod 7 is movably installed at the top of the lifting plate 5. Guide rods 8 are fixedly installed at both ends of the top of the lifting plate 5. A turntable 9 is fixedly installed at the top of the adjusting rod 7.

[0025] The lifting plate 5 is located inside the adjusting seat 4 and is arranged to slide up and down. Several stone retaining plates 6 are arranged at equal intervals. The lifting plate 5 drives the stone retaining plates 6 to slide up and down to adjust the height of the stone retaining plates.

[0026] The bottom end of the adjusting rod 7 is connected to the lifting plate 5 by a bearing. The adjusting rod 7 passes through the top of the adjusting seat 4 and is threaded. The adjusting rod 7 slides up and down through the thread, and the lifting plate 5 is raised and lowered and then fixed.

[0027] The guide rod 8 is fixedly installed with the lifting plate 5. The guide rod 8 slides through the top of the adjusting seat 4. The guide rod 8 moves up and down synchronously with the lifting plate 5, and the lifting plate 5 is stabilized when it moves up and down.

[0028] Specifically, the adjusting rod 7 rotates and, under the action of the thread, drives the lifting plate 5 to slide up and down, adjusting the bottom height of the stone stop plate 6 to match the height of the cutting disc. The stone stop plate 6 blocks the stones in front, reducing the damage of the stones to the cutting disc.

[0029] Example 2

[0030] See Figure 3 Furthermore, based on Embodiment 1, the material pushing assembly 3 includes a support frame 10, which is fixedly installed at the front of the adjusting seat 4. A motor 11 is installed on one side of the support frame 10, a shaft 12 is movably installed inside the support frame 10, and a spiral blade 13 is installed outside the shaft 12.

[0031] One end of the shaft 12 is fixedly connected to the output shaft of the motor 11, and the motor 11 drives the shaft 12 to rotate.

[0032] The other end of the shaft 12 is movably connected to the support frame 10, and the shaft 12 drives the spiral blade 13 to rotate.

[0033] Specifically, the motor 11 drives the shaft 12 and the spiral blade 13 to rotate, pushing the obstructing stones to one side, thereby reducing the damage to the trimmer disc caused by stones or other debris.

[0034] In actual operation, an electric motor is also installed on the top of the trimmer body 1, and the trimming guide plate at the bottom of the trimmer body 1 is rotated by the electric motor to trim.

[0035] When setting up a stone barrier, the rotating turntable 9 rotates the adjusting rod 7 and drives the lifting plate 5 to slide up and down under the action of the screw. The lifting plate 5 rises and falls smoothly through the guide rod 8, changing the distance between the stone barrier 6 and the ground. The bottom height of the stone barrier 6 is adjusted to match the height of the trimming disc. The grass stems pass through the gaps between the stone barriers 6 and block the stones in front of them through the stone barriers 6, reducing the damage of the stones to the trimming disc.

[0036] When pushing materials, the motor 11 is started, which drives the shaft 12 and the spiral blade 13 to rotate. The spiral blade 13 pushes the obstructing stones to one side, thereby reducing the damage of stones or other debris to the cutting disc.

[0037] By setting up the stone-blocking component 2, the adjusting rod 7 drives the lifting plate 5 to rise and fall. The lifting plate 5 rises and falls smoothly through the guide rod 8. The stone-blocking plate 6 can comb the grass stems and block the stones in front, making it easy to adjust the height of the stone-blocking plate and preventing large stones from damaging the trimming disc. By setting up the material-pushing component 3, the motor 11 drives the shaft 12 and the spiral blade 13 to rotate. The stones are blocked in front of the stone-blocking plate 6. The spiral blade 13 can push the blocked stones to one side, reducing the stones from entering and thus reducing damage to the trimming disc.
