Abstract

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。

Description

一种新型割草机刀片
技术领域
本发明涉及一种割草机配件,特别是涉及一种新型割草机刀片。
背景技术
市场上现有的割草机专用刀片呈长条形且二侧面设有割草刀刃,由于刀刃为直线形,较粗或韧性较强的草杆由于和刀刃的接触时间有限,会很快从刀刃处滑过并离开刀刃,不易被割断。而且现有刀片在长方形刀体外侧设置有锯齿对树枝树干进行割除时,由于刀体进行旋转运动,锯齿与树枝树干单位时间内接触面积小,难于对较大直径树枝树干的割除。
发明内容
本发明为克服上述现有技术的不足,本发明的目的在于提供便于对较大直径树枝树干和杂草进行割除处理的新型割草机刀片。
为实现上述目的,本发明的技术方案是:一种新型割草机刀片,由刀体,中孔,左锯齿和右锯齿构成,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。
本发明采用上述技术方案的有益效果是: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。
附图说明
图1为本发明的结构示意图。
图中:1.中孔,2.刀体,3.右锯齿,4.左锯齿,5.刀刃。
具体实施方式
下面结合附图和实施例对本发明作进一步的说明,但不构成对本发明的任何限制。
如图1所示,为实现上述目的,本发明的技术方案是:一种新型割草机刀片,由刀体2,中孔1,左锯齿4和右锯齿3构成,刀体2的中部设置有用于固定于割草机上的中孔1,刀体2两端分别设置有左锯齿4和右锯齿3,左锯齿4和右锯齿3位于同心圆的圆弧外侧,所述左锯齿4和右锯齿3弧长分别为四分之一圆弧,刀体2上设置有凹弧形刀刃5。
以上显示和描述了本发明的基本原理和主要特征。本行业的技术人员应该了解,本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下,本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
