Detailed implementation mode

[0023] To better illustrate and elaborate the content of the present utility model, the following will be described in conjunction with the drawings and implementation examples:

[0024] There is Figures 1 - 5 As shown, the present utility model discloses a height adjusting mechanism for a lawn mower with a grass-rolling wheel, including a chassis frame 1. The two sides of the chassis frame 1 are rotatably connected with a first shaft body 21 and a second shaft body 31. The two ends of the first shaft body 21 are rotatably connected with first wheels 2, and the two ends of the second shaft body 31 are rotatably connected with second wheels 3. An adjusting mechanism 900 for adjusting the height of the chassis frame 1 and the cutting height is provided on the first shaft body 21 and the second shaft body 31, and a grass-rolling wheel 36 for leveling the grass after cutting is provided on the adjusting mechanism 900.

[0025] Furthermore, the adjusting mechanism 900 includes first wheel shafts 22 fixedly connected to both ends of the first shaft body 21. The first wheel shafts 22 are not coaxial with the first shaft body 21. The first wheels 2 are provided on the first wheel shafts 22, and a connecting portion 23 is provided at the connection between the first shaft body 21 and one of the first wheel shafts 22.

[0026] Furthermore, both ends of the second shaft body 31 are connected with second wheel shafts 33. The second wheel shafts 33 are not coaxial with the second shaft body 31. The second wheels 3 are provided on the second wheel shafts 33.

[0027] Furthermore, a first mounting plate 34 and a second mounting plate 35 are respectively provided at the connection between the second shaft body 31 and the second wheel shafts 33. The grass-rolling wheel 36 is rotatably provided between the first mounting plate 34 and the second mounting plate 35.

[0028] Furthermore, a control board 32 is fixedly provided on the first mounting plate 34. Bumps 37 are provided on the control board 32. A plurality of mating grooves 11 are provided on the chassis frame 1. The bumps 37 can be inserted into the mating grooves 11 to lock the height of the chassis frame 1.

[0029] Furthermore, a transfer rod 4 is rotatably connected between the connecting portion 23 and the first mounting plate 34.

[0030] Furthermore, the control board 32 has elasticity and has a tendency to lean towards the mating groove 11.

[0031] Specifically, taking the position where the bottoms of the first roller 2 and the second roller 3 are located as the ground, the distance from the first shaft body 21 and the second shaft body 31 to the ground is the height of the chassis frame 1, that is, the mowing height;

[0032] During adjustment, manually move the control board 32 away from the chassis frame 1 so that the bump 37 moves out of the mating groove 11. At this time, the control board 32 can be rotated;

[0033] When the control board 32 is rotated, it will drive the first mounting plate 34 and the second mounting plate 35 to rotate around the second wheel shaft 33 as the rotation center, thereby changing the distance between the second shaft body 31 and the bottom of the second roller 3, that is, the height of the chassis frame 1 from the ground. After rotating to the appropriate position, insert the bump 37 into the new mating groove 11 to form a lock, and the tendency of the control board 32 to lean towards the mating groove 11 will prevent the bump 37 from moving out of the mating groove 11, ensuring the overall stability;

[0034] When the first mounting plate 34 rotates, it will drive the connecting part 23 to rotate through the transmission rod 4, that is, to realize the height adjustment at the first shaft body 21, and cooperate with the second shaft body 31 to realize the overall height adjustment of the chassis frame 1;

[0035] During the height adjustment, the grass rolling wheel 36 will also synchronously follow the second shaft body 31 to change the height, so that the grass can be leveled after cutting at different heights, making the cut grass more neat and beautiful;

[0036] Specifically during leveling, the chassis frame 1 moves forward and cuts the grass through the cutting knife installed inside. The cut grass is very messy and unsightly due to the action of the cutting knife. The grass rolling wheel 36 then rolls and levels the grass after the chassis frame 1 moves forward and finishes cutting, so that the cut grass is neat and beautiful without the need for secondary operation of leveling.

[0037] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.
