Description

一种割灌机刀片 技术领域
本实用新型是涉及一种林业割灌、割草及园林绿化用工具领域， 尤其是涉 及一种割灌机刀片的改进。
背景技术
割灌机主要用于割公路两旁杂草、 果园、 山坡或是不平整地灌木野草 等， 现在市售的割灌机刀片常用的有棱形、 长方形等， 由于其刀刃为如图 1 中所示为单面刃 1， 使得割灌机费油， 割灌的速度慢， 效率低。 另外， 这 种刀刃遇到硬物后刀刃处较易向无刃方向卷边、 变形， 阻力大时刀体固定 处易断裂、 损坏， 特别是刀体固定处断裂后容易造成机杆反弹、 震动力大， 极易给割灌机使用者带来伤害， 同时割灌机也易损坏， 因此给割灌机使用者 带来很大的不便和烦恼。
实用新型内容
本实用新型就是针对上述问题提出来的，目的是提供一种割灌安全、高效、 速度快， 割灌时遇硬物刀刃不易卷边、 变形， 刀体无损坏的割灌机刀片。
为了实现上述目的， 本实用新型解决技术问题的技术方案是： 一种割灌机 刀片， 包括刀体， 其在于刀体横向两端至少分别设有一个旋转刀刃体， 所述的 刀体与旋转刀刃体为铰接， 旋转刀刃体外端的刀刃为双面刀刃。
所述的旋转刀刃体为棱形、 方形、 长方形、 圆形、 半圆形中的任意一种。 所述的旋转刀刃体的非刀刃端设有斜面。
所述的刀体为棱形、 方形、 长方形中的一种。
本实用新型与现有技术相比具有下列优点和效果- 本实用新型由于采用在刀体横向两端设置旋转刀刃体，旋转刀刃体既可与 刀体同时旋转， 旋转刀刃体遇到硬物时又可反向收回， 此时刀体继续旋转， 无 震动， 又由于刀体与旋转刀刃体为铰接， 旋转刀刃体在刀体的惯性带动下可自 行打开， 继续工作， 因此在割灌过程中不仅对人体无伤害， 而且还减少了人体 的疲劳程度。另外， 由于旋转刀刃体采用了双面刀刃受力均匀，用于割灌直径
35mm时也不易卷边、 变形， 且刀体无断裂和震动， 本实用新型结果简单合 理， 既安全、 可靠， 又灵活方便， 割灌机采用本实用新型的割灌机刀片后， 噪 音小， 耗油少，切割效果平整， 且工作寿命长， 大幅度提高了工作效率， 降低 了使用成本， 最大限度地保障了使用者的人身安全。
附图说明
图 1是现有技术中一种割灌机刀具的主视结构示意图。
图 2是现有技术图 1的左视结构示意图。
图 3是本实用新型一种实施方式的主视结构示意图。
图 4是本实用新型图 2的俯视结构示意图。
图中： 单面刃 1， 刀体 2， 刀刃 3， 旋转刀刃体 4。
具体实施方式
下面结合具体实施例对本实用新型进行进一步详细说明，但本实用新型的 保护范围不受具体的实施例所限制， 以权利要求书为准。 另外， 以不违背本实 用新型技术方案的前提下，对本实用新型所作的本领域普通技术人员容易实现 的任何改动或改变都将落入本实用新型的权利要求范围之内。
实施例 1
如图 2、 3所示的本实用新型一种割灌机刀片， 其棱形的刀体 2横向两端 分别设有一个长方形的旋转刀刃体 4， 所述的刀体 2与旋转刀刃体 4通过销轴 铰接， 旋转刀刃体 4外端的刀刃 3为双面刀刃， 旋转刀刃体 4非刀刃端设有斜 面。
实施例 2
本实用新型一种割灌机刀片，其长方形的刀体 2横向两端分别设有一个圆 形的旋转刀刃体 4， 其它同实施例 1， 不再赘述。
