PROBLEM TO BE SOLVED: To provide a grain culm delivery structure of a combine that smoothens delivery conveyance without widening a guide width of a transfer guide, and properly performs the ON-operation of a clogging detection sensor on the occurrence of grain culm clogging.SOLUTION: A grain culm delivery structure of a combine is provided for detecting grain culm clogging by performing the ON-operation of a clogging detection sensor 36, using a transfer guide 30 deformed and moved by the grain culm clogged in a delivery unit 25 between a root conveying device 24 and a feed chain 4a. The grain culm delivery structure is configured such that a switch operation piece 37 having an abutment surface 37d inclined from a pushing unit 37c positioned below a switch piece 36a of the clogging detection sensor 36 toward a rearward upper part is provided between the switch piece 36a and the transfer guide 30, and the middle of the transfer guide 30 deformed and moved upward on the occurrence of clogging is brought into abutment with the abutment surface 37d, and thereby the switch piece 36a is made to perform the ON-operation through the pushing unit 37c.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】引継ガイドのガイド幅を広幅にすることなく受渡し搬送をスムーズにすると共に、穀稈詰り発生時に詰り検知センサのON動作を適切にすることができるコンバインの穀稈受渡し部構造を提供する。【解決手段】株元搬送装置24とフィードチェン4aとの受渡し部25に詰まる穀稈によって変形移動する引継ガイド30によって、詰り検知センサ36をON動作させ穀稈詰りを検出するコンバインの穀稈受渡し部構造であって、詰り検知センサ36のスイッチ片36aと引継ガイド30との間に、スイッチ片36aの下方に位置させる押動部37cから後方上方に向けて傾斜させた接当面部37dを有するスイッチ作動片37を設け、詰り発生時に上方に向けて変形移動する引継ガイド30の中途部を、接当面部37dに接当させて押動部37cを介しスイッチ片36aをON動作させる構成にした。【選択図】図3
