摘要:本实用新型涉及一种兼有旋耕和灭茬双功能的变速灭茬旋耕机。动力由拖拉机的动力输出轴,通过万向传动轴、传动箱的输入轴、经互相啮合的圆锥齿轮付传递至花键轴;花键轴上的换挡齿轮可分别与双联大齿轮或倒挡齿轮啮合,倒挡齿轮与双联小齿轮啮合,双联大齿轮与安装在输出花键轴上的输出齿轮啮合;装有刀具的刀轴紧固在传动箱两侧、输出花键轴的两端。只要拨动传动箱上的换挡手柄,就可快捷、方便、轻松地变换旋耕与灭茬作业时刀具所需要的旋向和转速,本实用新型具有结构简单、重心平稳、一机两用、操作简便和零部件通用化程度高等优点,可大大节省新机型的制造成本以及农户对农机具的投资、管理和耕作支出。

主权项:1.一种由万向传动轴、传动箱、刀轴、刀具和机罩组成的变速灭茬旋耕机,其特征在于:万向传动轴(1)与传动箱(3)中的动力输入轴(2)联接、互相啮合的圆锥齿轮(6、7)分别安装在动力输入轴(2)和花键轴(16)的端部,能在花键轴(16)上滑移的换挡齿轮(8)可分别与双联大齿轮(14)及倒挡齿轮(10)啮合,装在传动箱(3)外壁上的换挡手柄(9)通过连杆与插入换挡齿轮(8)边槽中的拨叉(15)联动;倒挡齿轮(10)与双联小齿轮(13)啮合,双联大齿轮(14)与安装在输出花键轴(11)上的输出齿轮(12)啮合,刀轴(21)依靠花键和螺栓(23)紧固在传动箱(3)的外侧、输出花键轴(11)的两端。
