PROBLEM TO BE SOLVED: To provide a dibbling technique capable of easily realizing sowing with a proper quantity by a simple structure with a small number of components.SOLUTION: A drum type direct sower which dibbles seeds filled inside a drum by rotating the drum is characterized as follows: protrusions are provided on a circumference of the drum; a dibble part is provided inside the protrusion; and after denting the ground by the protrusion, the seeds are sowed in the dent by the dibble part. By sowing in the dent formed by the protrusion, the seeds after sowing are prevented from moving so that an interrow space and a space between plants can be maintained. By filling the drum with the seeds and sowing by the dibble part provided on the circumference of the drum, it becomes unnecessary to provide a hopper, a feeding device, and other members separately.SELECTED DRAWING: Figure 6【課題】本発明は、部品点数の少ない簡単な構造で、適量の播種を容易に実現できる点播技術を提供する。【解決手段】ドラムを回転させて内部に充填される種子を点播するドラム式直播機であって、前記ドラムの外周に突起を設け、かつ、該突起内部に点播部を設け、前記突起で地面に凹みを付けた後に、前記点播部で該凹みの中に前記種子を播種することを特徴とする。突起によって形成される凹みの内部に播種することで、播種後の種子の移動を防ぎ、条間、株間の間隔を保つことができる。ドラム内に種子を充填させて、ドラムの外周に設けられる点播部で播種することでホッパ、繰出装置等の別途の部材が不要となる。【選択図】図6
