<P>PROBLEM TO BE SOLVED: To continue good threshing by properly keeping the threshing depth even when a small number of grain culms are reaped, in a combine harvester for reaping a large amount of the grain culms and threshing the grain culms. <P>SOLUTION: The grain culm-feeder for the combine harvester is constituted as follows. Grain culm sensors (31a, 31b, ...) for detecting the reaping grain culms for respective rows are installed in the front side position of a reaping apparatus (6), and the threshing is subjected to compulsory shallow threshing control where the threshing is changed to a shallower threshing side when any one (31a) of the grain culm sensors (31a, 31b, ...) does not detect the grain culm, compared to that when the whole sensors detect the grain culms, in the combine harvester obtained by installing ear tip sensors (32a, 32b) of the grain culms in the conveying route of the reaping apparatus (6), and feeding the grain culms to a threshing apparatus (4) by changing the nipping position in a conveyor (15) for regulating the threshing depth according to the ear tip positions of the grain culms detected by the ear tip sensors (32a, 32b) of the grain culms. <P>COPYRIGHT: (C)2012,JPO&INPIT |
