[0035] Embodiment 1
[0036] See Figures 1-2 As shown in the figure, the mower cutter includes a mounting frame 1 mounted on the output end of the mower, and at least two blade groups 2 are mounted from top to bottom on the mounting frame 1. The cutting diameter of the upper blade group 2 is greater than that of the lower blade group 2.
[0037] Through the arrangement of the at least two blade groups 2, the grass can be cut into at least three sections during mowing, so that the cut grass is more fragmented, and the residual grass on the lawn does not affect the photosynthesis of the grass, and can be quickly decomposed to provide certain nutrients for the soil.
[0038] In a further embodiment, the mounting frame 1 includes a first cutter holder 11 and a second cutter holder 12, the first cutter holder 11 is mounted above the second cutter holder 12, and at least two blade groups 2 are mounted on the first cutter holder 11 and the second cutter holder 12. By arranging the first cutter holder 11 and the second cutter holder 12, the distance between the blade groups 2 can be appropriately increased, and according to the actual use condition, the number of cutter holders can also be appropriately increased, for example, the number of cutter holders is increased to three or four, thereby lengthening the distance between the adjacent two blade groups 2. The structure is simple, the use effect is good, and the length of the grass cuttings can be ensured to be short. It can be understood that the length referred to in the embodiment is the length that the grass cuttings can be naturally decomposed and will not block and affect the photosynthesis of the grass.
[0039] As a preferred embodiment, the number of the blade groups 2 in the embodiment is two groups, one group of the blade groups 2 is installed on the first tool rest 11, and the other group of the blade groups 2 is installed on the second tool rest 12, and the cutting diameter of the blade groups 2 on the first tool rest 11 is greater than the cutting diameter of the blade groups 2 on the second tool rest 12. In other specific embodiments, the number of the blade groups 2 can also be three groups or four groups, or even more. The increase of the number of the blade groups 2 can ensure that the length of the grass cuttings can be shorter when cutting the grass.
[0040] It should be noted that when cutting the grass, the uppermost blade group 2 will first contact the grass and cut the upper end of the grass. According to the natural growth of the grass and the influence of environmental factors, the uppermost part of the grass is the softest, and the closer to the root part of the grass, the more tenacious it is. Therefore, the uppermost part of the grass will be curved. The diameters of the blade groups 2 of the utility model are different, so that after the uppermost blade group 2 cuts the uppermost part of the grass, the lower blade group 2 in turn cuts the grass, which ensures that the grass can be completely cut into at least three sections.
[0041] In further specific embodiments, the output end of the mower is a motor output shaft, and the middle parts of the first tool rest 11 and the second tool rest 12 are respectively provided with D-shaped grooves 4, and the motor output shaft penetrates the first tool rest 11 and the second tool rest 12 in turn through the D-shaped grooves 4.
[0042] The D-shaped grooves 4 are provided to facilitate the rotation of the first tool rest 11 and the second tool rest 12 driven by the motor, and the structure is simple and practical. It can be understood that in other specific embodiments, other connection methods such as screw fixing and installation can also be used to detachably install the first tool rest 11 and the second tool rest 12 on the output shaft of the motor, and there are many similar connection structures in the prior art, which will not be described here.
[0043] In further specific embodiments, the middle parts of the first tool rest 11 and the second tool rest 12 are respectively provided with through grooves 13 for passing grass cuttings. The top of the mounting frame 1 is provided with fan blades 3, and the output end of the mower penetrates the mounting frame 1 and the fan blades 3 in turn.
[0044] The through grooves 13 are provided so that the grass can fall to the ground through the through grooves 13 when being cut. The fan blades 3 are provided so that the fan blades 3 can collect and send the grass cuttings into the grass collecting box of the mower by rotating. It can be understood that in the case that the grass is cut into very small pieces and can be naturally decomposed without blocking and affecting the photosynthesis of the grass, the fan blades 3 can not be provided.
[0045] It should be noted that the diameter of the first tool rest 11 and the diameter of the second tool rest 12 are not necessarily the same, and the cutting diameter of the blade group 2 far from the grass root is greater than the cutting diameter of the blade group 2 close to the grass root.
[0046] Embodiment 2
[0047] See Figures 3-4 The difference between the present embodiment and Embodiment 1 is only that: "the number of blade groups 2 is two, the upper end of the mounting frame 1 is provided with an upper blade group 2, the lower end of the mounting frame 1 is provided with a lower blade group 2, the cutting diameter of the upper blade group 2 is greater than that of the lower blade group 2. A through slot 13 for passing grass clippings is formed in the middle of the mounting frame 1." The others are not repeated.
[0048] It should be noted that the mounting frame 1 in the present embodiment can be selected as a tool rest, so that the present embodiment can only use one tool rest. When mowing, the blade group 2 at the upper end of the mounting frame 1 first contacts the grass, and the blade group 2 at the lower end of the mounting frame 1 contacts the grass later, thereby cutting the grass into three sections, and the structure is simple.
[0049] Embodiment 3
[0050] The difference between the present embodiment and Embodiment 2 is only that: "the number of blade groups 2 is three, the upper end of the mounting frame 1 is provided with an upper blade group 2, the middle of the mounting frame 1 is provided with a middle blade group 2, and the lower end of the mounting frame 1 is provided with a lower blade group 2. The cutting diameter of the upper blade group 2 is greater than that of the middle blade group 2, and the cutting diameter of the middle blade group 2 is greater than that of the lower blade group 2." The others are not repeated.
[0051] It should be noted that the middle blade group 2 in the present embodiment can be installed at any position of the mounting frame 1, but the middle blade group 2 in the present embodiment is located in the middle of the mounting frame 1. The three blade groups 2 cut the grass respectively. The uppermost blade group 2 contacts the grass first, the middle blade group 2 contacts the grass second, and the lower blade group 2 contacts the grass last, thereby cutting the grass into three sections.
[0052] Embodiment 4
[0053] The turf maintenance station comprises all the technical features and beneficial effects of the mower tool of Embodiments 1-3, and thus is not repeated.
