PROBLEM TO BE SOLVED: To improve workability of harvesting work by devising to improve visibility in a grain tank.SOLUTION: A reaping apparatus (5) for reaping grain culms in the field and transferring them backward is provided in front of a travel device (2), and a threshing apparatus (3) for threshing the grain culms reaped by the reaping apparatus (5) is provided on one side of the upper part of the travel device (2). The grain tank (7) is provided on the other side of the upper part of the travel device (2), and an operating part (4) is provided on the front side of the grain tank (7). An upper inclined surface (24) inclining upward to the rear is formed at the upper part of a front side wall (21) of the grain tank (7), and the upper inclined surface (24) is provided with a transparent member (25) allowing light to shine into the grain tank (7). A front portion of a ceiling member (22) of the grain tank (7) is connected to the upper end of the upper inclined surface (24), and an inclined surface inclining to be high on the front side and to be low on the rear side is formed at the ceiling member (22). A predetermined position of the ceiling member (22) is provided with an openable/closable inspection cover (28).COPYRIGHT: (C)2013,JPO&INPIT【課題】グレンタンク内の視認性を向上するように工夫して、収穫作業の作業性を向上させる。【解決手段】走行装置(2)の前方に圃場の穀稈を刈取って後方へ移送する刈取装置(5)を設け、走行装置(2)の上部一側に刈取装置(5)で刈り取った穀稈を脱穀する脱穀装置(3)を設け、走行装置(2)の上部他側にグレンタンク(7)を設け、グレンタンク(7)の前側に操縦部(4)を設け、グレンタンク(7)の前側壁(21)の上部に後上がり傾斜する上部傾斜面(24)を形成し、上部傾斜面(24)にはグレンタンク(7)内に光を差し込ませる透明部材(25)を設け、上部傾斜面(24)の上端には前記グレンタンク(7)の天井部材(22)の前側部分を接続し、天井部材(22)には前側を高く後側を低く傾斜させた傾斜面を形成し、天井部材(22)の所定位置には開閉自在な点検蓋(28)を設ける。【選択図】図1
