PROBLEM TO BE SOLVED: To solve a problem in that in a conventional sowing machine installing a sowing device and a groove-forming tool at a machine body frame supporting a front wheel and rear wheel in its front and rear, since the delivering port of the sowing machine is arranged as leaving at a higher position in upper direction than that of the groove-forming tool and seeds delivered from the delivering port are greatly accelerated during the fall in a guide member, violently collide within a sowing groove and greatly rolling to surroundings, dealing with sowing work requiring a high sowing accuracy such as spaced sowing is difficult.SOLUTION: This sowing machine is provided by including low position-supporting structures 116, 145 for supporting the sowing device 14 at a low position, also installing a communicating hole 76b and an upper part opening 15d, communicating with the sowing groove by passing through the inside of a groove-forming claw 15 at the upper part or directly upper direction of the groove-forming claw 15, and arranging the delivery port 91a of the seeds 93 from the sowing device 14 at a directly upper approaching space of the communicating hole 76b and upper part opening 15d.COPYRIGHT: (C)2013,JPO&INPIT【課題】従来の、前後に前輪と後輪を支承した機体フレームに播種装置と作溝具とを設けた播種機では、播種装置の繰出口が作溝具より上方の高位置に離間して配置されるため、該繰出口から繰り出された種子は、ガイド部材内を落下中に大きく加速され、播種溝内に激しく衝突して周囲に大きく転動するため、点播のように高い播種精度が要求される播種作業への対応が困難である、という問題があった。【解決手段】播種装置14を低位置で支持する低位置支持構造116・145を備えると共に、作条爪15の上部または直上方に、該作条爪15内を通って播種溝に連通する連通孔76b・上部開口15dを設け、該連通孔76b・上部開口15dの直上近接空間に前記播種装置14からの種子93の繰出口91aを配置した。【選択図】 図6
