PROBLEM TO BE SOLVED: To provide a two-row seedling feeding device comprising a seedling receiving conveyor for inverting, receiving and conveying seedling of two rows connected in a manner that they can be separated into two vertical stages connected to be separated into individual seedlings, and then fed to a planting device, the two-row seeding device being able to prevent the loss of the plants without dropping the planting speed, even the seedling fed is deficient into one row shape.SOLUTION: At a position confronting the transportation face of a seedling receiving conveyor 11, there is disposed a seedling deficient sensor 18 for detecting the existence of the seedling at an upper stage, so that the transportation speed of the seedling receiving conveyor 11 is accelerated when the deficiency of the seedling of the upper step is detected by the seedling deficient sensor 18.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2017,JPO&INPIT【課題】 個々の苗に分離可能に連結した二列の列状の苗を上下二段になるように倒置して受入、搬送する苗受入コンベアを備え、分離装置へ受け渡して個々の苗に分離し、その後植付装置に供給する供給装置において、欠損して一列状になった苗を供給しても、移植速度を落さずに欠株を防止できる二列苗の供給装置を提供する。【解決手段】 苗受入コンベア11の搬送面と対向した位置に上段の苗の有無を検知する苗欠損センサ18を設け、苗欠損センサ18により上段の苗の欠損を検知したときに苗受入コンベア11の搬送速度を増速させるようにした。【選択図】図5
