PROBLEM TO BE SOLVED: To provide a direct sower capable of making a uniform depth of sowing in direct sowing on a water-filled field.SOLUTION: This direct sower is provided by equipping a seed tank 85 for storing the seeds, a delivering part 87 for delivering the seeds intermittently, and a first transporting tube 93 and a second transporting tube 95 for transporting the delivered seeds to the sowing position of the field, in a direct sowing device 82 that is equipped at a traveling vehicle and sowing seeds in the field, installing a gap between the two transporting tubes 93, 95 and supplying air to the gap from an air-supplying part 97 to obtain pressurized wind. By using pressurized wind, the seeds and a fertilizer or a medicine can be struck into the field, to a desired sowing depth, with the desired sowing point distribution.COPYRIGHT: (C)2009,JPO&INPIT【課題】湛水直播における播種深度が均一になる直播機を提供すること。【解決手段】走行車両に設けた圃場内に種子を播くための直播装置８２に、種子を貯留する種子タンク８５と種子を間欠的に繰り出す繰出部８７と繰り出された種子を圃場の播種位置へ移送する第一移送管９３と第二移送管９５を備え、二つの移送管９３，９５の接続部分に隙間を設けて、該隙間に空気供給部９７から空気を供給して圧力風を得る。この圧力風で種子、肥料あるいは薬剤を圃場に所望の播種深さ及び所望の点播分布で打ち込むことができる。【選択図】図２
