Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1, fig. 1 is a schematic view of a thin and light lawn mower according to an embodiment of the present disclosure. As shown in the figure, the efficient light and thin mowing blade comprises an alloy substrate 10, wherein the alloy substrate 10 is provided with a horizontal central ring part 11, a transition ring part 12 which surrounds the central ring part 11 and stretches towards one side, and a bevel ring part 13 which surrounds the transition ring part 12, and the bevel ring part 13 is inclined to the central ring part 11 and is 15 degrees away from the central ring part 11; the sawing parts 20 are annularly arranged on the inclined plane ring part 13, each sawing part 20 comprises a first sawtooth 21 and a second sawtooth 22 which are spaced, and the first sawtooth 21 is lower than the second sawtooth 22; and a plurality of silencing lines 30 arranged on the inclined plane ring part 13, wherein the silencing lines 30 are arranged in a circumferential array.

The utility model discloses an in the embodiment, horizontally central ring portion 11 has central through-hole for firm installation mower knife rest, the transition ring portion 12 on outer edge then is stretched by central ring portion 11, and slick and sly transition produces the difference in height, cooperates the inclined plane ring portion 13 that the slant set up simultaneously, can be convenient for deal with unevenness's meadow, avoids the stone to collide with, also can protect mower knife rest. The inclined ring part 13 and the central ring part 11 form a 15-degree included angle, and the angle is moderate, so that the flying rotation is prevented from being influenced too much.

The utility model discloses a 20 interval arrangements of sawtooth portion, first sawtooth 21 and second sawtooth 22 that have one big one little, in an embodiment, the distance that can set up second sawtooth 22 and be higher than first sawtooth 21 is 8mm, arrange according to the cutting direction simultaneously, little first sawtooth 21 is located the front end, tentatively cut off the weeds bush, the big second sawtooth 22 of rear end realizes mainly cutting off, the two-stage transition, play the effect that a buffering rear end second sawtooth 22 strikes, the durability has been improved, and need not to weld the tool bit in addition, make saw bit itself more frivolous, it is more convenient to process. Wherein, the first saw tooth 21 and the second saw tooth 22 are connected through an arc notch 23 to achieve the chip removal effect.

It is worth mentioning that the one end slope of the relative arc notch 23 of first sawtooth 21 is greater than the one end slope of the relative arc notch 23 of second sawtooth 22, follows the cutting direction promptly, and the front end slope of sawtooth portion 20 is great, is convenient for high-efficiently mow, and the rear end slope is less, the transition chip removal of being convenient for, and is practical high-efficient.
