Description
Technical Field
The application belongs to the technical field of grass cutting blades, and particularly relates to a dual-purpose cutting saw blade.
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 to be solved by the present application is to provide a dual-purpose cutting saw blade, which is adapted to cutting different shrub weeds by respectively providing a serrated portion and a blade folding portion on two opposite sides of a sawn cutting corner, thereby avoiding the trouble of single saw blade and low efficiency in the past.
In order to solve the technical problem, the utility model discloses a dual-purpose cutting saw blade, which comprises a saw blade base body, wherein the saw blade base body is provided with a central through hole; the saw cutting angles are annularly arranged on the saw blade substrate, are separated by the chip removal notches and are symmetrical about an axis; the sawtooth part is arranged on one side of the sawn corner; and the folding edge part is arranged on the other side of the saw cutting angle and is connected with the sawtoothed part in a radian manner.
According to an embodiment of the present invention, the width of the sawing angle is gradually reduced from the center of the saw blade body to the outside, and the sawing angle is arrow-shaped.
According to an embodiment of the present invention, the saw teeth are densely distributed on the saw teeth portion; the folding edge part is provided with a cutting edge which is folded by 15 degrees.
According to an embodiment of the present invention, the saw cutting corners have a weight-reducing hole in the center.
According to an embodiment of the utility model, the saw blade body is coated with a hardening coating.
Compared with the prior art, the application can obtain the following technical effects:
the sawtoothed part and the folding edge part are respectively arranged on the two opposite sides of the sawn cut angle, so that the cutting tool is suitable for cutting different shrub weeds, and the trouble of single saw blade and low efficiency in the past is avoided.
Of course, it is not necessary for any product to achieve all of the above-described technical effects simultaneously in order to practice the present application.
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 dual purpose cutting saw blade according to an embodiment of the present application.
Reference numerals
The saw blade comprises a saw blade body 10, a central through hole 11, a sawing angle 20, a chip removal notch 30, a sawtooth part 40, a blade part 50 and a lightening hole 60.
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 dual purpose cutting saw blade according to an embodiment of the present disclosure. As shown in the drawings, a dual purpose cutting saw blade includes a blade body 10, the blade body 10 having a central through hole 11; the saw cutting angle 20 is arranged around the saw blade body 10, and the saw cutting angle 20 is separated by the chip removal notches 30 and is symmetrical about an axis; a saw tooth portion 40 provided on one side of the sawn corner 20; and a blade 50 disposed at the other side of the sawn corner 40, the blade 50 being arc-connected to the sawn portion 40.
In one embodiment of the utility model, the central through hole 11 of the saw blade body 10 is used for easy mounting, and is surrounded at its edges by equidistant cutting corners 20 and chip-removing recesses 30 for chip removal. The sawn corner 20 is axisymmetric, and is provided with a sawn portion 40 and a blade portion 50 in the clockwise and counterclockwise directions, respectively, and the sawn portion and the blade portion are connected in a radian manner, thereby realizing smooth transition, accelerating cutting and improving efficiency.
Preferably, the width of the saw cutting angle 20 is gradually reduced from the center of the saw blade body 10 to the outside, and the saw cutting angle is arrow-shaped, so that symmetrical end surfaces on two sides are realized, and the saw cutting angle is practical and stable.
The sawtooth part 40 is densely distributed with sawteeth, so that the cutting of shrubs such as twigs and the like is realized, the cutting effect is enhanced, and the durability is improved; the folding edge part 50 has a cutting edge which is folded by 15 degrees, so that flat ground such as weeds can be conveniently cut, the sharpness is improved, and the efficiency is higher.
In addition, the center of the sawing angle 40 is provided with a lightening hole 50, so that the weight is reduced, the vibration is reduced, and meanwhile, the silencing effect is also achieved.
The saw blade matrix 10 is coated with a hardened coating to increase overall hardness and 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. 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.
