PROBLEM TO BE SOLVED: To uniformly supply onions with leaves in the width direction of arrangement to a tapping apparatus equipped with a plurality of screw conveyors arranged in parallel in a harvested onion treating machine for cutting the stem and leaf parts of onions with stems and leaves.SOLUTION: The harvested onion treating machine includes a conveying means for conveying supplied onions with stems and leaves, and the tapping apparatus for giving tapping treatment to the onions with stems and leaves supplied from the conveying means. The tapping apparatus includes the plurality of screw conveyors arranged in parallel to turn the direction of the stems and leaves in one direction while moving the supplied onions with stems and leaves, and a stem and leaf cutting means arranged at the downstream end of the screw conveyors. The conveying means includes at least a supply conveyor 25 for supplying the onions with stems and leaves to the screw conveyors. The supply conveyor 25 has a breadth W corresponding to the arrangement width of the screw conveyors, and has a conveying surface 25F whose center part C extended along the breadth W direction is higher than the end E.COPYRIGHT: (C)2012,JPO&INPIT【課題】茎葉付き玉葱の茎葉部分を切除処理する収穫玉葱処理機において、複数並列配置したスクリューコンベアを備えたタッピング装置に対して配列幅方向に均一に葉付き玉葱を供給することができる。【解決手段】投入された茎葉付き玉葱を搬送する搬送手段と、搬送手段から供給される茎葉付き玉葱をタッピング処理するタッピング装置とを備え、タッピング装置は、供給された茎葉付き玉葱を移動しながらその茎葉の向きを一方向に向けるスクリューコンベアを複数並列配置し、スクリューコンベアの下流側端部に茎葉の切除手段を配置し、搬送手段は、スクリューコンベアに茎葉付き玉葱を供給する供給コンベア25を少なくとも備え、供給コンベア25は、スクリューコンベアの配列幅に応じた横幅Wを有すると共に、横幅W方向に沿った中央部Cを端部Eより高くした搬送面25Fを有する。【選択図】図5
