阅读说明：本技术 一种新型割草机刀片 (Novel mower blade ) 是由 尹素君 于 2020-08-31 设计创作，主要内容包括：本发明公开了一种新型割草机刀片,由刀体,中孔,左锯齿和右锯齿构成,其特征在于：刀体的中部设置有用于固定于割草机上的中孔,刀体两端分别设置有左锯齿和右锯齿,左锯齿和右锯齿位于同心圆的圆弧外侧,所述左锯齿和右锯齿弧长分别为四分之一圆弧,刀体上设置有凹弧形刀刃。本发明采用在同心圆的圆弧外侧设置左锯齿和右锯齿,在马达的驱动下,左右锯齿做旋转运动,能有效锯除直径较大的树枝树干；同时,由于本发明的刀刃为凹弧形,这可以大大增加草杆与刀刃的接触时间,提高草杆被切断效率。(The invention discloses a novel mower blade, which consists of a cutter body, a middle hole, a left sawtooth and a right sawtooth, and is characterized in that: the middle part of the cutter body is provided with a middle hole used for being fixed on a mower, the two ends of the cutter body are respectively provided with a left sawtooth and a right sawtooth, the left sawtooth and the right sawtooth are positioned on the outer sides of circular arcs of concentric circles, the arc lengths of the left sawtooth and the right sawtooth are respectively a quarter circular arc, and the cutter body is provided with a concave arc-shaped cutting edge. The left saw teeth and the right saw teeth are arranged on the outer sides of the arcs of the concentric circles, and the left saw teeth and the right saw teeth rotate under the driving of the motor, so that branches and trunks with larger diameters can be effectively sawed; meanwhile, the cutting edge of the straw cutting machine is in the shape of a concave arc, so that the contact time of the straw and the cutting edge can be greatly prolonged, and the cutting efficiency of the straw is improved.)

1. The utility model provides a novel mower blade, by the cutter body, the mesopore, left sawtooth and right sawtooth constitute its characterized in that: the middle part of the cutter body is provided with a middle hole used for being fixed on a mower, the two ends of the cutter body are respectively provided with a left sawtooth and a right sawtooth, the left sawtooth and the right sawtooth are positioned on the outer sides of circular arcs of concentric circles, the arc lengths of the left sawtooth and the right sawtooth are respectively a quarter circular arc, and the cutter body is provided with a concave arc-shaped cutting edge.

Technical Field

The invention relates to a mower accessory, in particular to a novel mower blade.

Background

The existing special blade for the mower in the market is in a long strip shape, the two sides of the blade are provided with mowing edges, and the blade is in a linear shape, so that a thick or tough straw rod can quickly slide from the blade and leave the blade due to limited contact time with the blade, and is not easy to cut. And when current blade was provided with the sawtooth in the rectangle cutter body outside and cuts off the branch trunk, because the cutter body carries out rotary motion, the sawtooth is little with branch trunk contact area in unit time, is difficult to cutting off of great diameter branch trunk.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and aims to provide a novel mower blade which is convenient for cutting off the branches, trunks and weeds with larger diameters.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a novel lawn mower blade, by the cutter body, the mesopore, left sawtooth and right sawtooth constitute, the middle part of cutter body is provided with the mesopore that is used for being fixed in on the lawn mower, and the cutter body both ends are provided with left sawtooth and right sawtooth respectively, and left sawtooth and right sawtooth are located the circular arc outside of concentric circles, left side sawtooth and right sawtooth arc length are the fourth circular arc respectively, are provided with concave arc shape cutting edge on the cutter body.

The invention adopts the technical scheme that the method has the beneficial effects that: the left saw teeth and the right saw teeth are arranged on the outer sides of the arcs of the concentric circles, and the left saw teeth and the right saw teeth rotate under the driving of the motor, so that branches and trunks with larger diameters can be effectively sawed; meanwhile, the cutting edge of the straw cutting machine is in the shape of a concave arc, so that the contact time of the straw and the cutting edge can be greatly prolonged, and the cutting efficiency of the straw is improved.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

In the figure: 1. the cutter comprises a center hole, a cutter body 2, right sawteeth 3, left sawteeth 4 and a blade 5.

Detailed Description

The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention in any way.

As shown in fig. 1, in order to achieve the above object, the technical solution of the present invention is: the utility model provides a novel mower blade, by cutter body 2, mesopore 1, left sawtooth 4 and right sawtooth 3 constitute, the middle part of cutter body 2 is provided with mesopore 1 that is used for being fixed in on the lawn mower, and 2 both ends of cutter body are provided with left sawtooth 4 and right sawtooth 3 respectively, and left sawtooth 4 and right sawtooth 3 are located the circular arc outside of concentric circles, left sawtooth 4 and 3 arc lengths of right sawtooth are the fourth circular arc respectively, are provided with concave arc shape cutting edge 5 on the cutter body 2.

The foregoing shows and describes the general principles and features of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
