To provide a root crop harvesting machine in which irregular crops such as crops with very short roots or forked crops in the root crops being dug up from a field are removed while being conveyed to a sorting unit without requiring expensive equipment such as an imaging device or a control unit, and thereby the sorting work by the sorting unit is simplified and the efficiency of the harvesting work can be promoted.SOLUTION: A root crop harvesting machine is provided with a shoulder alignment device 5 for aligning the shoulders of the crops in the lower part of a pull-out conveying device 1 for pinching and sending the foliage of the root crops vegetated in a field to the rear while pulling them out, and enables a root alignment device 4 for cutting the foliage with a foliage cutting blade 6 and aligning the roots in the rearward of the shoulder alignment device 5 to be conveyed to a sorting belt 13 and sorted, and thereby contains good crops in a container K. The root crop harvesting machine is characterized in that a shape sensor 7 is provided at the root part passage position of the crops suspended with the shoulder alignment device 5, and irregular crop exclusion means 14 is provided for identifying the irregular crops with the shape sensor 7 and excluding the irregular crops from the conveyance to the root alignment device 4.SELECTED DRAWING: Figure 1【課題】本発明は、圃場から掘り上げた根菜を、撮像装置やコントロールユニット等の高価な機器を要しないで、選別部に搬送する間に根部が短すぎるものや二股になったもの等の異形作物を取り除いて選別部での選別作業を簡略して収穫作業を効率化出来る根菜類収穫機とすることを課題とする。【解決手段】圃場に植生する根菜類作物の茎葉を挟持して引き抜きながら後方へ送る引抜搬送装置１の下部に作物の肩を揃える肩揃え装置５を設け、該肩揃え装置５の後部に茎葉切刃６で茎葉を切断して根部を根部揃え装置４で選別ベルト１３に搬送して選別し良品をコンテナＫに収容する根菜類収穫機において、肩揃え装置５で吊り下げた作物の根部通過位置に形状センサ７を設け、該形状センサ７で異形作物を識別し、異形作物を根部揃え装置４への搬送から排除する異形作物排除手段１４を設けたことを特徴とする根菜類収穫機とする。【選択図】図１
