Abstract

本实用新型涉及一种打草机的切削刀具,其特征在于:它包括刀盘[2]和固定于刀盘[2]上的数个刀片[4],所述的刀片[4]的刀刃[5]处呈外凸的弧形。所述的刀刃[5]上设有加强筋。所述的刀刃[5]的一面上排列有多个球缺口[3],所述的球缺口[3]之间的凸起形成加强筋。本实用新型具有切削效率高、使用寿命长的优点,用于对草坪的修剪。

Description

打草机的切削刀具
本实用新型涉及一种打草机。
现有技术中,打草机的刀盘上设有两根尼龙绳,刀盘由电机带动而高速旋转,故高速旋转的尼龙可以将草打断,可用于修剪草坪。但是尼龙绳容易磨损折断,使用者需要经常更换尼龙绳。另外,尼龙绳的切削效率低。
本实用新型的目的在于提供一种具有较高切削效率的打草机的切削刀具。
本实用新型的技术方案是:它包括刀盘和固定于刀盘上的数个刀片,所述的刀片的刀刃处呈外凸的弧形。
本实用新型与现有技术相比具有下列优点:
(1).由于刀刃呈弧形,故刀片碰到草茎时,随着刀片的旋转,刀片可由里向外端对草茎切割,减小草茎与刀具的冲击力,充分利用刀刃的切削作用,可延长发具的使用寿命。
(2).由于刀刃的一面上排列有多个球缺口,故没有球缺口处的刀刃就形成了加强筋,能使较薄的刀刃具有较高的强度;另外,刀刃平面的球缺口使得一面刀刃呈凹凸不平状,在对草茎切削时有锯齿的作用,故切削效果好。
(3).多个刀片固定于刀盘上,可以方便地更换某一个损坏的刀片,分立的刀片可以减少刀片的重量和材料。
下面结合附图及实施例对本实用新型作进一步的描述:
附图1为本实用新型的结构主视图;
附图2为刀片的主视图;
附图3为附图2所示刀片的后视图;
附图4为附图2的A-A方向剖视放大图;
其中:[1].连接卡孔;[2].刀盘;[3].球缺口;[4].刀片;[5].刀刃。
实施例:参见附图1,本实用新型包括刀盘[2]和固定于刀盘[2]上的数个刀片[4],所述的刀片可为2片~4片,在附图1中采用了3片刀片,所述的刀片[4]的刀刃[5]处呈外凸的弧形。这样,刀片如同弯刀,在对草茎切削时,较长的刀刃段可以在短时间内切削同一根草茎。由于刀刃[5]较薄,为了增加刀刃的强度而又不减小刀刃的锋利度,所述的刀刃[5]上设有加强筋,所述的刀刃[5]的一面上排列有多个如同月牙状的球缺口[3](见附图1和附图2所示),各球缺口[3]之间的凸起即为加强筋,加强筋可为其它形式。见附图3所示,刀刃的另一面仍为平面的刀刃。当然刀刃[5]的两个面上也可以均有球缺口,但球缺口最好错开。所述的刀片[4]的端部设有连接卡孔[1],该连接卡孔[1]嵌在刀盘[2]下方凸出的端柱上,使刀盘[2]和刀片[4]相固定连接。
