Description

High-efficient grass cutting piece

Technical Field

The utility model belongs to the technical field of the metal instrument, specifically speaking relates to a high-efficient grass cutting piece.

Background

The saw blade used for mowing is faced with a severe environment, such as branches, grass roots and stems, small stones and the like, and the severe environment has extremely high requirements on the strength and the cutting performance of the saw blade. The existing grass cutting sheet has low cutting performance, is difficult to quickly cut off roots, stems and branches of some grass and the like, is easy to wind a cutter, and can seriously cause the conditions of edge collapse and the like.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims to solve the technical problem that a high-efficient grass cutting piece is provided, the lower problem of cutting performance of saw bit among the prior art has been solved.

In order to solve the technical problem, the utility model discloses a high-efficiency grass cutting blade, which comprises a grass cutting blade main body, a mounting hole arranged at the central position of the grass cutting blade main body and a plurality of saw teeth arranged on the grass cutting blade main body; the sawtooth is provided with a front convex angle, an inner convex angle and a rear convex angle, and the front convex angle is higher than the rear convex angle; and a circular notch is formed between two adjacent saw teeth.

Further, the angle of the notch formed by the front convex angle and the inner convex angle is acute.

Further, the width of the notch formed by the inner convex angle and the rear convex angle is not larger than the radius of the circular notch.

Further, the number of the saw teeth is 26.

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

the utility model can enhance the cutting ability and has stronger destructiveness to the grass cutting some thick rootstocks by arranging the front convex angle and the inner convex angle on the sawtooth; a circular notch is formed between every two adjacent sawteeth, the width of the notch formed by the inner convex angle and the rear convex angle is not more than the radius of the circular notch, and the notch is in a shape with a narrow front part and a wide rear part and is smooth, so that the cutting machine can pull grass well and is more convenient to cut; the increased number of teeth further improves cutting performance.

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

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 high-efficiency grass cutting blade according to an embodiment of the present invention.

Reference symbols of the drawings

The structure comprises sawteeth 1, a circular notch 2, a front convex angle 3, an inner convex angle 4, a rear convex angle 5, an acute angle a, a radius b and a width c.

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-efficiency grass cutting blade according to an embodiment of the present invention. A high-efficiency grass cutting blade comprises a grass cutting blade main body, a mounting hole arranged at the center of the grass cutting blade main body and a plurality of saw teeth 1 arranged on the grass cutting blade main body; the sawtooth 1 is provided with a front convex angle 3, an inner convex angle 4 and a rear convex angle 5, wherein the front convex angle 3 is higher than the rear convex angle 4; a circular notch 2 is formed between every two adjacent sawteeth 1; the notch angle formed by the front convex angle 3 and the inner convex angle 4 is an acute angle a; the width c of the notch formed by the inner convex angle 3 and the rear convex angle 5 is not larger than the radius b of the circular notch 2; the number of teeth 1 is 26.

The utility model has the advantages that the front convex angle 3 and the inner convex angle 4 are arranged on the sawtooth 1, and the front convex angle 3 and the inner convex angle 4 form the acute angle a notch, so that the cutting capability can be enhanced, and the cutting capability is stronger to grass types with thick roots and stems; a circular notch 2 is formed between every two adjacent sawteeth 1, the width c of a notch formed by the inner convex angle 4 and the rear convex angle 5 is not more than the radius b of the circular notch 2, and the shape of being narrow in front and wide in rear and smooth is formed, so that the grass can be well pulled, and the cutting is more convenient; the increased number of teeth 1 further improves the cutting performance.

While the foregoing description shows and describes several preferred embodiments of the invention, it is to be understood, as noted above, that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
