Reference numerals
The saw blade comprises a saw blade base body 10, a saw blade mounting hole 11, saw teeth 20, saw teeth 30, upper saw teeth 31, lower saw teeth 32, a first silencing hole 40, a chip groove 50 and a second silencing hole 60.
Detailed Description
The following detailed description will be made with reference to the accompanying drawings and examples, so that how to implement the technical means of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.
Referring to fig. 1, fig. 1 is a schematic view of a mowing saw blade with high efficiency and noise reduction according to an embodiment of the present invention.
As shown, an efficient noise dampening mowing saw blade, comprising: the saw blade comprises a saw blade base body 10, wherein a saw blade mounting hole 11 is formed in the center of the saw blade base body 10; the setting is at the sawtooth portion 20 of saw bit base member 10 marginal round, is equipped with the even sawtooth 30 of a plurality of intervals on the sawtooth portion 20, and the width of sawtooth 30 is by outer within first diminishing gradually then crescent, and sawtooth 30 includes: the bottom of the lower saw tooth 32 is provided with a first silencing hole 40; flutes 50 are provided between adjacent serrations 20.
In one embodiment of the present invention, a saw blade mounting hole 11 is formed in the center of the saw blade base 10 for mounting the mowing saw blade. The surface of the saw blade base body 10 is coated with a hardened coating to enhance the strength of the mowing saw blade and prevent the mowing saw blade from being damaged when the mowing saw blade touches a hard object.
The saw blade body 10 is provided with a plurality of saw teeth 20 at a circle at the edge, and the saw teeth 20 are provided with a plurality of saw teeth 30 at uniform intervals, and preferably, each group of saw teeth 20 is provided with 3 groups of saw teeth 30. The width of the serrations 30 is gradually reduced from the outside to the inside and then gradually increased. The saw teeth 30 include: upper serrations 31 and lower serrations 32. The edges of the serrations 30 are provided with cutting edges for better cutting of the object. Preferably, the included angle between the upper teeth 31 and the lower teeth 32 is 135 to 150 °, and the teeth 30 have high strength and high cutting performance.
The utility model discloses a through set up the even sawtooth 30 in a plurality of intervals in sawtooth portion 20, the width of sawtooth 30 is reduced gradually then crescent by outer to interior earlier, and the sawtooth cutting strength of this structure is big, and the sawtooth is difficult for collapsing, and cutting performance is strong.
