In order to solve the technical problem, the utility model discloses a novel mowing saw blade, which comprises an alloy substrate, wherein the alloy substrate is provided with a central through hole; the arc blade parts are annularly arranged on the plurality of arc blade parts of the alloy substrate and provided with outer arc parts and straight cutting parts, wherein the outer arc parts extend from the edge of the alloy substrate to the outer radian, the straight cutting parts linearly extend from the outer ends of the outer arc parts to the edge of the alloy substrate, and the included angles between the straight cutting parts and the outer arc parts are acute angles; and a plurality of folding edges annularly arranged on the inner side of the alloy substrate, wherein the folding edges are provided with folding edges along the cutting direction.
According to an embodiment of the present invention, an angle between the blade bending portion and the alloy substrate is set to be 20 ° to 30 °.
According to an embodiment of the present invention, the edge folding portion is located at two end edges of the folding edge and forms a right angle.
According to an embodiment of the present invention, the folding edge has an outward-expanding arc.
According to an embodiment of the present invention, the alloy substrate is coated with a hardening coating.
Compared with the prior art, the application can obtain the following technical effects:
the outer arc edge part of the alloy substrate is matched with the inner folding edge part, double cutting is achieved, the mowing efficiency is improved, and the problems that the conventional mowing blade is single in saw tooth and insufficient in strength and sharpness are avoided.
Of course, it is not necessary for any one product to achieve all of the above technical results simultaneously.
Drawings
The accompanying drawings, which are included to provide a further understanding of the application and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the application and together with the description serve to explain the application and not to limit the application. In the drawings:
fig. 1 is a schematic view of a novel grass cutting saw blade according to an embodiment of the present application.
Reference numerals
The cutting device comprises an alloy substrate 10, a central through hole 11, an arc-shaped blade part 20, an outer arc-shaped part 21, a straight cutting part 22, a folding blade part 30 and a folding edge 31.
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 novel mowing saw blade according to an embodiment of the present application. As shown, a novel grass cutting saw blade includes an alloy substrate 10, the alloy substrate 10 having a central through hole 11; the arc blade parts 20 are annularly arranged on the alloy substrate 10, each arc blade part 20 is provided with an outer arc part 21 and a straight cutting part 22, the outer arc part 21 extends from the edge of the alloy substrate 10 to the outer radian, the straight cutting part 22 extends from the outer end of the outer arc part 21 to the edge of the alloy substrate 10 in a straight line, and the included angle between the straight cutting part 22 and the outer arc part 21 is an acute angle; and a plurality of blade folding portions 30 annularly arranged at the inner side of the alloy substrate 10, wherein the blade folding portions 30 are provided with folding edges 31 along the cutting direction.
In one embodiment of the utility model, the alloy substrate 10 is stamped and formed with a central through hole 11 for mounting. A plurality of arc blade parts 20 are arranged on the edge of the alloy substrate 10 in a surrounding mode and used for high-speed mowing. Specifically, the arc blade 20 has an outer arc 21 extending from the edge of the alloy substrate 10 in an outward arc and extending back to straighten the edge of the alloy substrate 10 at the other end by a straight cutting portion 22 to form a convex cutting body for cutting shrub and weed. In addition, a plurality of folding edge parts 30 are arranged on the inner side of the alloy substrate 10 in a surrounding mode, and the folding edge parts 31 are arranged along the clockwise cutting direction and used for fully cutting off weed and shrubs on the inner side and further cutting weeds, meanwhile, potential safety hazards of winding caused by too dense parts can be prevented, and practical performance is enhanced.
Preferably, the included angle between the folding edge part 30 and the alloy substrate 10 is set to be 20-30 degrees, the included angle is small, and the potential safety hazard of fracture caused by too large possibility of folding is prevented.
In one embodiment, the two end edges of the folding edge portion 30 located at the folding edge 31 are right-angled, that is, the folding edge portion 30 is entirely right-angled triangular, but the folding edge 31 with the hypotenuse preferably has an outwardly-expanding radian, and is smooth in transition, convenient, practical, and highly efficient.
The alloy substrate 10 is coated with a hardened coating to enhance durability.
The foregoing description shows and describes several preferred embodiments of the present application, but as aforementioned, it is to be understood that the application is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the application as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art.
