In order to solve the technical problem, the utility model discloses an anti-curl grass cutting blade, which comprises an alloy disc, wherein the alloy disc is provided with a central through hole; the saw cutting parts are annularly arranged on the alloy disc and are spaced from each other through chip grooves, each saw cutting part comprises a first branch part, a second branch part connected with the first branch part through an arc-shaped notch, and a cutter blade head which is welded to the arc-shaped notch and protrudes out of the second branch part, wherein the second branch part is higher than the first branch part and is wider than the first branch part; and four turning angles which are arranged on the alloy disc and are circumferentially arrayed on the central through hole, wherein the turning angles are turned over at a preset angle on the alloy disc and are provided with arc blades in the same cutting direction as the blade heads.

According to the utility model discloses an embodiment, wherein above-mentioned chip groove becomes the U type, and the opening is gradually big from outside to inside.

According to the utility model discloses an embodiment, wherein the rear end of above-mentioned second branch portion is along downwarping, and the rear end height is higher than first branch height 3 mm.

According to an embodiment of the present invention, the predetermined angle is 20 ° -30 °.

According to an embodiment of the present invention, the edge turning angle is coated with teflon.

Compared with the prior art, the application can obtain the following technical effects:

the blade head is stabilized through the saw cutting part with the first supporting part and the second supporting part, the strengthening stability is realized, meanwhile, the blade turning angle is turned over by the alloy disc to be discharged, redundant shrub weeds are cut, and the potential safety hazard caused by the fact that a mower knife rest is involved is avoided.

Of course, it is not necessary for any one product to achieve all of the above-described technical effects simultaneously.

reference numerals

The cutting tool comprises an alloy disc 10, a central through hole 11, a sawing part 20, a first branch part 21, a second branch part 22, a cutting edge head 23, an arc-shaped notch 24, a chip removing groove 30, a turning edge 40 and an arc-shaped edge 41.

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 an anti-curl grass-cutting blade according to an embodiment of the present application. As shown in the drawings, an anti-curl grass-cutting blade comprises an alloy disk 10, the alloy disk 10 having a central through hole 11; the plurality of sawing parts 20 are annularly arranged on the alloy disc 10, the sawing parts 20 are mutually spaced through the chip grooves 30, each sawing part 20 comprises a first branch part 21, a second branch part 22 connected with the first branch part 21 through an arc-shaped notch 24, the second branch part 22 is higher than the first branch part 21 and is wider than the first branch part 21, and a blade head 23 welded to the arc-shaped notch 24 and protruding out of the second branch part 22; and four turning angles 40 arranged on the alloy disk 10 and circumferentially arrayed on the central through hole 11, wherein the turning angles 40 are turned over at a predetermined angle on the alloy disk 10 and are provided with arc blades 41 in the same cutting direction as the blade heads 23.

In one embodiment of the present invention, the central through hole 11 of the alloy disc 10 is used to mount a cutter to a mower blade holder, and the saw cuts 20 spaced by the flutes 30 form a blade cutting portion body having a lower first leg 21; the second branch portion 22 connected and higher through the arc-shaped notch 24 and the width of the second branch portion 22 are also wider, which can provide sufficient support for the blade tip 23 welded at the arc-shaped notch 24.
