<P>PROBLEM TO BE SOLVED: To provide a combine harvester performing smooth threshing work by relaying grain culms from a reap pretreatment part to a transfer starting end of a feed chain. <P>SOLUTION: An auxiliary relaying chain (9a) is placed at an inner position of the transfer starting end of the feed chain (22), and rotary power is transmitted from a rear part of the reap pretreatment device (3) through a transmission device to the auxiliary relaying chain (9a). Base parts of a first grain culm guide (24) and a second grain culm guide (25) for guiding grain culms are attached to the attaching member (26) of the side of the reap pretreatment device (3), the first grain culm guide (24) is extended backward, the rear end of the first grain culm guide (24) is positioned above the auxiliary relaying chain (9a), the second grain culm guide (25) is extended backward, the rear end of the second grain culm guide (25) is positioned above the transfer starting end of the feed chain (22), and the first grain culm guide (24) is crossed with the second grain culm guide (25) by planar view. <P>COPYRIGHT: (C)2012,JPO&INPIT |
