JP2002253030A - Safeguard of grass-separating rod in reaper of planted stem and calm crop - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the problem that a grass-separating rod does not follow the upper and lower movement and sticks into the ground at the position having many unevenness in a field but the grass-separating rod is freely turnable in the upper and lower direction, although conventionally the grass-separating rod becoming a grounding body is attached to a reaper corresponding to each ridge of vertical stems and culms so as to be freely turning upper and lower. SOLUTION: This safeguard of the grass-separating rod has a spinning bar attached to the tip of the grass-separating rod through a fulcrum and grounding just on the surface of the ground in normal times, and constantly directed in the front direction by an extension coil spring, and is constituted so that when the tip part of the grass-separating rod is just stuck into the ground, the spinning bar may be reversed and fixed to form a dog-leg shape.
