Description

Multiple cutting point's grass cutting piece

Technical Field

The application belongs to the technical field of grass cutting blades, and particularly relates to a grass cutting blade with multiple cutting points.

Background

The grass cutting blade is a disc-shaped saw blade which is arranged on the mower and provided with a mounting hole in the center, and grass and trees are cut through rotation. However, the existing grass cutting blade has single saw teeth, can only be used for flat grasslands such as playgrounds or clean flower beds and lawns, is difficult to cut the grasslands mixed with shrubs and branches, is easy to damage the cutting edge of the grass cutting blade, and can also cause the grass cutting blade to collapse and splash to the periphery in serious conditions to cause potential safety hazards.

SUMMERY OF THE UTILITY MODEL

In view of this, the technical problem that this application will solve provides a grass-cutting blade of multiple cutting point, through two-way sawtooth cooperation triangle sawtooth, realizes multiple cutting breakpoint, avoids the single trouble of grass-cutting blade sawtooth in the past, intensity and sharpness are not enough.

In order to solve the technical problem, the utility model discloses a mowing sheet with multiple cutting points, which is integrally formed by punching and comprises an alloy substrate, wherein the alloy substrate is provided with a central through hole; the bidirectional saw teeth are annularly arranged on the alloy substrate and are provided with oppositely-oriented cutting corners, and a V-shaped cutting edge is arranged between the cutting corners; and triangular saw teeth arranged between the two-way saw teeth, wherein the triangular saw teeth are lower than the two-way saw teeth.

According to an embodiment of the present invention, the two-way saw tooth is symmetrical about an axis, and the outer side of the cutting corner has a concave curvature.

According to an embodiment of the present invention, the triangular saw teeth are equidistant from the two-way saw teeth on both sides, and have a height at least half of the height of the cutting corner.

According to an embodiment of the present invention, the number of the bidirectional saw teeth is 20.

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:

through two-way sawtooth cooperation triangle sawtooth, realize multiple cutting breakpoint, avoid in the past the lawn mower sawtooth single, intensity and sharpness are not enough troublesome.

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

Reference numerals

The cutting tool comprises an alloy substrate 10, a central through hole 11, bidirectional sawteeth 20, a cutting corner 21, a cutting edge 22 and triangular sawteeth 30.

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 lawn mower with multiple cutting points according to an embodiment of the present disclosure. As shown in the figure, the mowing sheet with multiple cutting points is integrally formed by punching and comprises an alloy substrate 10, wherein the alloy substrate 10 is provided with a central through hole 11; a plurality of spaced bidirectional saw teeth 20 annularly arranged on the alloy substrate 10, wherein the bidirectional saw teeth 20 are provided with oppositely-oriented cutting corners 21, and a V-shaped cutting edge 22 is arranged between the cutting corners 21; and triangular serrations 30 disposed between the bidirectional serrations 20, the triangular serrations 30 being lower than the bidirectional serrations 20.

In one embodiment of the present invention, the alloy substrate 10 is formed by stamping, the middle of the alloy substrate has a central through hole 11 which is convenient to install, the outer edge is provided with two-way saw teeth 20, and the triangular saw teeth 30 are arranged at intervals and are matched with each other to generate three breakpoints, so as to break shrubs and weeds and realize multiple cutting. Specifically, two sides of the bidirectional saw tooth 20 are provided with cutting corners 21 facing opposite directions, the cutting corners are pointed, and a V-shaped cutting edge 22 is formed in the middle of the bidirectional saw tooth, so that the cutting is convenient, the cutting corners 21 can be fully resisted, and the using strength is enhanced.

Preferably, the bidirectional saw teeth 20 are symmetrical about an axis, and the outer sides of the cutting corners 21 have concave arcs, so that the bidirectional saw teeth are smoothly transited, are not easy to break when cutting weeds, and improve the durability.

In addition, the triangular saw teeth 30 are lower and are uniformly distributed at equal distances from the bidirectional saw teeth 20 on the two sides, so that the influence on use caused by uneven stress is avoided. And the height is at least half of the height of the cutting angle 21, so that the full weed cutting is realized, and meanwhile, shrub branches are broken, and the sharpness is improved.

In one embodiment, the number of the bidirectional saw teeth 20 is 20, which is uniformly arranged and convenient for cutting weeds.

In addition, the alloy substrate 10 is coated with a hardened coating to improve strength and increase service life.

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, and is not to be construed as excluding other embodiments, but rather is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the application as expressed 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.
