PROBLEM TO BE SOLVED: To provide a crop digger for digging taro, etc., and capable of digging the crop from a field, separating daughter tubers and secondary tubers from a mother tuber and, recovering the mother tuber as a waste, and recovering the daughter tubers and secondary tubers as harvests without using human work.SOLUTION: Taro is dug up from ground with a digger blade 19 the dug-up taro is transported backward above with a slat belt 14 constituting an endless track the taro is pressed from right and left with a separating device 3 on the slat belt 14 during transportation and separated into the mother tubers and the daughter or secondary tubers and the daughter tubers and the secondary tubers are dropped on a lower ridge through a declining transfer slope 18 placed at the back of the slat belt 14. The ridge left after digging the tuber is pressed with a compacting roller 40 mounted under a downstream side of the transporting direction of a transporting device 6.COPYRIGHT: (C)2012,JPO&INPIT【課題】圃場から掘り起こすと共に親芋から子芋や孫芋を分離し、同時に人手によらないで、親芋を廃棄物として回収し、子芋や孫芋を収穫物として回収できる里芋などの作物掘起し装置を提供すること。【解決手段】里芋を地中から掘起刃19で掘り起し、掘り起こされた里芋を無限軌道を構成するスラットベルト14により後上方へ搬送し、搬送中にスラットベルト14上の分離装置3で里芋を左右から押圧して親芋と子芋・孫芋とに分離し、スラットベルト14の後部に設けた後下り傾斜姿勢の搬送傾斜部18より子芋・孫芋を下方の畝上に落下させる。また、搬送装置6の搬送方向下手側の下部に設けた鎮圧ローラ40で作物を掘り取った後の畝を押し固める。【選択図】図2
