圆盘刀人力割禾器的设计

Design of the Disc Sickle Labor Power Cutter

设计了圆盘刀人力割禾器,其推进只是起到行走和预切割部分茎秆的作用,切割主要由动刀旋转来完成。设计的动、定刀片皆为齿刀,且皆可自磨锐,作业时动刀片每个齿都参与切割,所以磨损较均匀,切割功率随时间增加反而有所下降,基本解决了原割禾器存在的刀片磨损集中,寿命低的问题。

Disc sickle labor power cutter is designed which advanced attachment makes function as walking and precutting part straw, cutting finished by cutter section rotation. Since every blade is tooth-blade and self-acute, even every tooth of section blade is attached to cutting, wear is equality, cutting power descend with time increase. The design has settled the problem of unbalanced wearing and lowlife of original cutter.
