PROBLEM TO BE SOLVED: To provide a lid structure of a pumped body case in a combine, the structure that facilitates work corresponding to the type of maintenance work in the pumped body case and enables car washing work using car washing water to be performed in high efficiency.SOLUTION: A lid structure is provided in a pumped body case 13 forming a square shape cross section of a first conveyor device 10 for pumping and conveying primary grain or a second conveyor device 11 for pumping and conveying secondary grain. In that case, a lower opening 43a having a lower opening lid 46 for performing maintenance work in a lower side of the pumped body case 13 and an upper opening 43 having an upper opening lid 41 for performing maintenance work in a middle upper side of the pumped body case 13 are provided in the lower part and the upper part at the side of a case front wall 13 g of the pumped body case 13. Also, the lower opening 43a and the lower opening lid 46 of the lower side are formed into a lid structure being made smaller than the upper opening 43 and the upper opening lid 41 of the upper side.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】揚送本体ケース内のメンテナンス作業の種別に対応した作業を容易にすると共に、洗車水を利用した洗車作業を高能率に行うことができるコンバインにおける揚送本体ケースの蓋構造を提供する。【解決手段】一番物を揚上搬送する一番コンベア装置10又は二番物を揚上搬送する二番コンベア装置11の方形状断面となした揚送本体ケース13に蓋構造を設けるに、揚送本体ケース13のケース正面壁13g側の下部と上部に、揚送本体ケース13の下部側内のメンテナンス作業を行なう下開口蓋46を有する下開口部43aと、揚送本体ケース13の中途部上方側内のメンテナンス作業を行なう上開口蓋41を有する上開口部43とを設けると共に、下部側の下開口部43a及び下開口蓋46を、上部側の上開口部43及び上開口蓋41より小さくした蓋構造にする。【選択図】図4
