PROBLEM TO BE SOLVED: To improve a pulling-out conveying apparatus for digging up residual culms planting in a field by a digging-up device and nipping, pulling-up and conveying the dug residual culms. SOLUTION: In the pulling-up conveying apparatus 9, a pair of left and right endless feed chains 9e is oppositely installed and mutually inwardly turned and the residual culms are nipped and pulled up and conveyed in conveying start ends and the residual culms are discharged from conveying final ends and adjusting wheels 9f for adjusting nip-starting positions and release positions by the feed chains 9e are installed so as to enable adjustment of longitudinal transfer in conveying start ends and conveying final ends of the endless feed chains 9e. Idle wheels 9h for adjusting stretching state of the endless feed chains 9e are arranged so as to stretch the feed chains 9e from the inside to the outside. Mobile wheels 9j for adjusting nipping force of a pair of feed chains 9e are movably supported through spring 9k. Chain guides for guiding the feed chains 9e are engaging wheels 9l engaging with the feed chains 9e. COPYRIGHT: (C)2005,JPO&NCIPI
