PROBLEM TO BE SOLVED: To enable three or more workers to be arranged by a circulation conveyor of a machine body for sorting work of crops collected from above a farm and elimination work of a clod, stone, and a bad crop, etc. mixed in and sent with the crops to enhance work efficiency, and to collect the sorted crops into a collection box without damaging them.SOLUTION: A pallet circulation conveyor S arranging therein plural pallets S1 in a square shape is arranged in a farm work machine G. In a front part of the machine body, an endless slat conveyor N1 picking up potatoes and a lift conveyor N2 are arranged. In outer peripheral three sides of the pallet circulation conveyor S, three chairs C are arranged and a box installment device H is arranged in a central lower part, the box installment device holding a collection box B so as to be inclined initially and lowering and holding horizontally the collectin box B when many potatoes are stored. In a middle of the pallet circulation conveyor S, a belt conveyor F arranging an endless belt F1 vertically is arranged so as to cross obliquely a sending direction of the pallet circulation conveyor S. Crops on the pallets S1 are dropped into the collection box B in an inner side central lower part.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】 畑上から回収された農作物の選別作業と、農作物とともに混在して送られる土塊・石・不良農作物等の排除作業を、機体の循環コンベア傍で3名以上の作業員を配置できて作業効率を高める。又、選別された農作物を回収箱へ傷つけることなく回収する。【解決手段】 農作業機Gにロ字状に複数のパレットS1を配置したパレット循環コンベアSを設け、機体前部にじゃがいもを拾い上げる無端スラットコンベアN1と持ち上げコンベアN2を設け、パレット循環コンベアSの外周三辺に椅子Cを3個設け、中央下方には回収箱Bを初期的に傾斜させるように保持し、じゃがいもが多く収容されると回収箱Bが下降して水平に保持する箱設置装置Hを設け、パレット循環コンベアSの途中に無端ベルトF1を垂直にしたベルトコンベアFをパレット循環コンベアSの送り方向と斜交するように設け、パレットS1上の農作物を内側中央下方の回収箱Bへ落下させる。【選択図】図2
