PROBLEM TO BE SOLVED: To provide a receiving net removable structure of a threshing unit in which demount work of a receiving net can easily be performed efficiently by detachment means for forcibly separating a right receiving net to the left direction from front and rear mounting frames without preparing for a special tool and damaging the right receiving net.SOLUTION: A receiving net removable structure of a threshing unit is provided for mounting the upper side of a right receiving net 21R through top detachable means pluggable to the right machine wall 6e side, and detachably mounting the lower frames 33dL/33dR of the lower side part of the left and right receiving nets 21 L/21R to front and rear mounting frames 27 through insertion fastening of an undersize frame bolt 30, when detachably mounting the left receiving net 21 L and the right receiving net 21R along a threshing cylinder to a threshing chamber frame 26 installed in the longitudinal direction and the back and forth mounting frames 27 for connecting both nets. The receiving net removable structure is configured by providing detachment means 40 for forcibly separating the lower frame 33dR from the front and rear mounting frames 27 to the left direction to the right receiving net 21R while detaching the undersize frame bolt 30.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2017,JPO&INPIT【課題】受網の取外し作業を、特別な工具を準備したり右受網を損傷させることなく、前後取付フレームから右受網を左方向に強制的に離間させる離脱手段によって、能率よく簡単に行うことができる脱穀部の受網着脱構造を提供する。【解決手段】扱胴に沿って左受網21Lと右受網21Rとを、前後方向に設置される扱室フレーム26と、両者を連結する前後取付フレーム27に着脱自在に取付けるに、該右受網21Rの上辺部を右機壁6e側に抜き差し自在とする上部着脱手段を介して取付けると共に、左右受網21L・21Rの下辺部の下枠33dL・33dRを前後取付フレーム27に網下枠ボルト30の挿入締着を介して着脱自在に取付ける脱穀部の受網着脱構造において、右受網21Rに、網下枠ボルト30を外した状態で下枠33dRを、前後取付フレーム27から左方向に強制的に離間させる離脱手段40を設けた構成にする。【選択図】図8
