[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-4 A crawler-type remote-controlled lawn mower that prevents blade damage includes a control body 1, a crawler-type walking mechanism 2 is installed at both the front and rear ends of the control body 1, a slot body 5 is provided at the front end of the control body 1, a first telescopic cylinder 4 is installed inside the slot body 5, and a push plate 3 is installed at the bottom end of the first telescopic cylinder 4, and a second telescopic cylinder 19 is installed at the bottom end of the control body 1. The second telescopic cylinder 19 is provided in four groups, and the four symmetrically distributed second telescopic cylinders 19 drive the connecting seat 14 to move up and down stably. The four groups of second telescopic cylinders 19 are symmetrically distributed about the central axis of the connecting base 14, and the connecting base 14 is installed at the bottom end of the second telescopic cylinder 19. The bottom end of the connecting base 14 is installed with a rotating base 12 through a rotating shaft 20, and mowing blades 13 are installed on both sides of the bottom end of the rotating base 12. A servo motor 21 is installed at the top of the rotating shaft 20. There are two groups of first telescopic cylinders 4. The two groups of first telescopic cylinders 4 drive the push plate 3 to form a telescopic mechanism, so that the push plate 3 can move up and down for use or storage;

[0024] Specifically, if Figure 1 and Figure 3As shown, when the lawn mower starts to move forward to mow the grass, the first telescopic cylinder 4 is first opened in advance to push the push plate 3 to move downward to form a baffle at the front end of the control body 1. Then, when the lawn mower moves, the push plate 3 is pushed forward to push the stones in the grass forward, so as to prevent the mowing blade 13 from cutting the stones and causing damage when mowing the grass.

[0025] Embodiment 2: The bottom end of the rotating shaft 20 is movably provided with a protective mesh cover 9, and both sides of the top of the protective mesh cover 9 are fixed with a mounting seat 10, and the top of the mounting seat 10 is provided with a mounting groove 11, and the mounting groove 11 is provided inside the mounting groove 11, and the bottom end of the mounting seat 10 is fixed with a clamping seat 17, and the outer side wall of the clamping seat 17 is movably provided with a snap ring 18, and one side of the snap ring 18 is fixed with a connecting rod 16, and one side of the connecting rod 16 is movably provided with a rotating block 15, and the top of the rotating block 15 is aligned with the mounting groove 11. The bottom end is fixed, the cross section of the snap ring 18 is adapted to the cross section of the card seat 17, and a snap-fit structure is formed between the snap ring 18 and the card seat 17. The cross section of the mounting seat 10 is smaller than the cross section of the mounting groove 11, and a snap-fit structure is formed between the mounting seat 10 and the mounting groove 11. Two groups of mounting seats 10 are provided, and the two groups of mounting seats 10 are symmetrically distributed about the central axis of the protective net cover 9. The symmetrically distributed mounting seats 10 and the design of the snap-fit structure facilitate the installation of the protective net cover 9 and its disassembly and maintenance, and are more convenient to use;

[0026] Specifically, if Figure 1 As shown, when the lawn mower is used outdoors, outdoor sunlight shines on the surface of the solar panel 8. After receiving the sunlight, the solar panel 8 converts it into electrical energy and stores it in the battery 7. The battery 7 then transmits the electrical energy to the lawn mower to provide power for it, which is more energy-saving and environmentally friendly.

[0027] Example 3: A base 6 is installed on the top of the control body 1, a battery 7 is installed on the top of the base 6, and a solar panel 8 is installed on one side of the top of the base 6;

[0028] Specifically, if Figure 2 and Figure 3 As shown, the protective net cover 9 is mounted on the outer wall of the rotating shaft 20 so that the mounting seats 10 on both sides are engaged with the mounting grooves 11 inside the connecting seat 14, and then the connecting rod 16 is rotated to engage with the seat 17 at the bottom end of the mounting seat 10, thereby installing the protective net cover 9 at the bottom end of the rotating shaft 20 to prevent grass from being entangled with the outer wall of the rotating shaft 20 when mowing.

[0029] Working principle: When the present invention is in use, the crawler walking mechanism 2 is activated by the wireless remote control technology assembled inside the control body 1 to control the lawn mower to move to the grass, and the first telescopic cylinder 4 is turned on to push the push plate 3 to move downward to form a baffle at the front end of the control body 1. Later, when the lawn mower moves, the push plate 3 is pushed forward to push the stones in the grass forward. When mowing the grass, the second telescopic cylinder 19 is turned on to push the rotating seat 12 to move to the appropriate position height, and the servo motor 21 is started to drive the rotating shaft 20 to rotate. The rotation of the rotating shaft 20 drives the lawn mower 13 to rotate to cut the grass on the grass. When the lawn mower is used outdoors, the outdoor sunlight shines on the surface of the solar panel 8. After receiving the light, the solar panel 8 converts it into electrical energy and stores it in the battery 7. The battery 7 then transmits the electrical energy to the lawn mower to provide power for it.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
