Abstract

一种双动刀切割器及驱动装置,属农作物机械收割技术领域,由上、下动刀,曲柄连杆机构及驱动箱组成,上、下动刀是由往复切割刀片和刀杆组成的刀条。两连杆两端分别与上、下动刀和曲柄铰接,两曲柄做在驱动箱输出轴输出端的同一轴心平面的两边,组成双曲柄轴,曲柄半径为切割刀片间距的一半,双曲柄轴由驱动箱的圆锥齿轮驱动,从而带动双动刀往复运动,进行收割作业。

Description

一种双动刀切割器及驱动装置
技术领域
本技术属农业机械技术领域。特别涉及农作物收割机械。
背景技术
农作物机器收割方式主要有往复切割器和圆盘刀切割器两种。而往复切割器又分单动刀切割器和双动刀切割器两种。
单动刀由于高频率的方向变换时惯性力对割刀驱动装置产生较大冲击和震动,影响了割刀驱动装置的正常工作,降低了使用寿命,可靠性较差。
双动刀上、下动刀作速度相同、行程相等、方向相反的往复运动,在速度相同时曲柄半径缩短一半,行程相同时,速度提高一倍。同时,往复运动的惯性力相互抵消。采用两套驱动机构,分别驱动上下动刀,结构复杂,占用空间。
发明内容
本技术的目的是克服上述缺陷。
本技术克服上述缺陷,采取的技术方案是:该装置由上下动刀,曲柄连杆机构和驱动箱组成。上、下动刀均是由高强度往复式切割刀片和刀杆组成的刀条。两连杆两端分别与上下动刀和两曲柄铰接。两曲柄连成一体,固结在驱动箱输出轴输出端的同一轴心平面的两边,组成双曲柄轴。曲柄半径为切割刀片节距的一半。双曲柄轴由驱动箱的圆锥齿轮驱动,从而实现上、下动刀的往复运动,完成切割。
采用本技术的有益效果是:将单动刀变成双动刀,惯性力相互抵消,平衡性好;将双向两个驱动装置合二为一,节约了制造成本,腾出了空间位置。
附图说明:
图1为双动刀切割器及驱动装置主视示意图,图2为双动刀切割器及驱动装置俯视(平面)示意图。
图中1为下动刀,2为上动刀,3为连杆,4为曲柄,5为驱动箱。
具体实施方式:
下面结合附图对本技术做进一步的说明。如图1,图2所示,由下动1,上动刀2、连杆3,曲柄4,驱动箱5组成。上、下动刀,是由高强度往复切割刀片和刀杆组成的刀条,两连杆的两端分别与上、下动刀和两曲柄铰接,两曲柄连成一体,固接在驱动箱输出轴输出端的同一轴心平面的两边组成双曲柄轴,曲柄半径为切割刀片节距的一半。双曲柄轴由驱动箱的圆锥齿轮传动,从而带动上、下动刀往复运动完成切割作业。
与单动刀切割器相比,惯性力相互抵消,平衡性好,与双向驱动的双动刀切割器相比,节省一个驱动装置,腾出了空间位置,如在苎麻双作用立式割台中应用,驱动装置设在左端,右端便于麻杆向后输送。
