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 high-speed high-efficiency mowing saw blade with a double-edged blade according to an embodiment of the present application. As shown in the figure, a high-speed high-efficiency mowing saw blade with double-edged blade comprises a blade body 10, wherein the blade body 10 is provided with a central through hole 11 for installation; the turning edges 20 are arranged on the saw blade matrix 10 and are positioned on two opposite sides of the central through hole 11, the turning edges 20 are formed by folding the saw blade matrix 10, and chip removal notches 30 are formed between the turning edges 20 and the saw blade matrix 10; the saw blade comprises a saw tooth part 40 annularly arranged on the edge of the saw blade base body 10, the saw tooth part 40 has the same cutting direction with the turning edge 20, a U-shaped chip groove 50 is arranged between the saw teeth of the saw tooth part 40, the bottom of the U-shaped chip groove 50 is provided with a radian cutting groove 60, and the radian cutting groove 60 is gradually thickened along the center of the saw blade base body 10 and reaches the same thickness as the saw blade base body 10.
In one embodiment of the present invention, the saw blade base body 10 has a central through hole for installation in the center, so that the saw blade base body 10 can be installed and fixed. The edge of the outer ring is provided with a sawtooth part 40, and the sawtooth is used for cutting at a high speed when the outer ring rotates at a high speed, so that the outer ring is suitable for various weeds and shrubs. The U-shaped chip grooves 50 are spaced by adjacent sawteeth to discharge the impurity chips. In addition, the radian cutting groove 60 extending at the bottom of the U-shaped chip removal groove 50 is thinned from inside to outside, so that chips can be removed more quickly during cutting, and the transition property is good.
The turning edges 20 are located on opposite sides of the central through hole 11, have the same cutting direction as the serrations 40, and are formed by turning the blade body 10. Preferably, the cutting of shrubs is realized by folding 15-20 degrees, meanwhile, the cutting is further matched with the sawtooth part 40 of the outer ring, weed shrubs are fully cut off, the chip removal notch 30 prevents potential safety hazards of winding caused by excessive density, and the practicability is enhanced.
Specifically, the turning edge 20 comprises a first straight cutting edge 21 at the front end to realize main cutting at the front end, a second blade handle 22 extending from the rear end is supported at the rear part to improve the strength, and the radian of the height of the second blade handle 22 is gradually reduced to gradually transit to the saw blade base body 10.
In a preferred embodiment, the first straight cutting edge is inclined by 45 degrees, is suitable for rotary cutting, and has a moderate angle, so that the problem that the angle is too flat and the durability is reduced is avoided.
The chip removal notch 30 comprises round notches 31 at two ends of the turning edge 20 and a round notch 32 which is communicated with the round notches 31 and is annularly arranged on the turning edge 20. In this embodiment, the circular groove opening 31 has a circular arc transition, so as to improve the toughness of the turning blade 20, and the circular groove opening 32 exposes the chip removal outlet of the turning blade 20, thereby facilitating better weed removal and avoiding winding.
In addition, a plurality of rings of damping holes 70 are arranged between the saw tooth part 40 and the turning edge 20, so that the weight is reduced, and the thinness of the saw blade matrix is improved.
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. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the application, which is to be protected by the claims appended hereto.
