Description

脚踏式安全镰刀
技术领域
本发明涉及一种农具，具体地说是一种脚踏式安全镰刀。
背景技术
镰刀作为一种收割、砍伐的农具被广泛应用于农业生产中，但是由于传统镰刀结构简单、刀刃锋利，使用时稍有不慎会伤害到操作者的身体，造成严重的安全事故，威胁人们的生命财产安全，尤其在砍伐玉米高粱等直径较大、高度较高的农作物秸秆时，需弯腰操作，不但费时费力，而且镰刀容易打滑，存在一定的安全隐患。
发明内容
针对上述不足，本发明提供了一种脚踏式安全镰刀，该镰刀通过脚踏板来控制刀片的工作过程，防止刀片划伤手，使用安全方便。
本发明是通过以下技术实现的：一种脚踏式安全镰刀，其结构包括底座、套筒、固定刀片、转动刀片、木柄、固定销、脚踏板、螺线槽柱、弹簧；其特征在于：木柄一端插入套筒内，并用固定销固定，固定刀片固定在套筒中部，转动刀片位于固定刀片上方，所述的脚踏板固定在螺线槽柱上，弹簧上端固定在螺线槽柱下端，弹簧下端固定在底座上端，螺线槽柱、弹簧位于套筒内部，底座与套筒螺纹连接，转动刀片上的销钉在螺线槽柱内。
本发明的有益效果是：使用镰刀时，由于是通过踩踏板来控制刀片的打开和关闭，既能保护手不被刀片划伤，又能解放出双手做辅助动作，使用安全方便，由于是通过脚部的力量控制刀片的工作，所以避免了弯腰，省时省力。
附图说明
图1为本发明的外部结构图；
图2为本发明的内部结构图；
图中：1、底座，2、套筒，3、固定刀片，4、转动刀片，5、木柄，6、固定销，7、脚踏板，8、螺线槽柱，9、弹簧。
具体实施方式
如图1、图2所示，一种脚踏式安全镰刀，包括底座1、套筒2、固定刀片3、转动刀片4、木柄5、固定销6、脚踏板7、螺线槽柱8、弹簧9；其特征在于：木柄5一端插入套筒2内，并用固定销6固定，固定刀片3固定在套筒2中部，转动刀片4位于固定刀片3上方，所述的脚踏板7固定在螺线槽柱8上，弹簧9上端固定在螺线槽柱8下端，弹簧9下端固定在底座1上端，螺线槽柱8、弹簧9位于套筒2内部，底座1与套筒2螺纹连接，转动刀片4上的销钉在螺线槽柱8内,踩下脚踏板7，带动螺线槽柱8向下移动，通过转动刀片4上的销钉与螺线槽的配合使转动刀片4转动，弹簧9可使被踩下的脚踏板7复位。
使用时，握住木柄1，将待砍伐的农作物秸秆根部卡在转动刀片4和固定刀片3之间，踩踏脚踏板7使得螺线槽柱8克服弹簧9的弹力向下移动，转动刀片4上的销钉与螺线槽的配合使转动刀片4转动，通过转动刀片4与固定刀片3间的剪切力将农作物秸秆剪断。
本发明的镰刀由于是通过踩踏板来控制刀片的打开和关闭，既能保护手不被刀片划伤，又能解放出双手做辅助动作，使用安全方便，由于是通过脚部的力量控制刀片的工作，所以避免了弯腰，省时省力。
