Abstract

A cross-feed screw shaft (87) for feeding a seedling-placement platform (16) in a transverse direction and a transmission shaft (96), in a drive case (61) for planting, for transmitting drive force to the screw shaft (87) are formed as separate bodies. The cross-feed screw shaft (87) and the transmission shaft (96) are connected and interlocked outside the drive case (61) for planting. In a rice-planting machine with the cross-feed screw shaft for feeding the seedling-placement platform in a transverse direction, the burden of dismantling the drive case (61) for planting each time when the cross-feed screw shaft (87) breaks down is removed, and only the screw shat (87) can be easily replaced. As a result, workability for maintenance and checking is improved.

本発明は、 苗載台を横送りする横送りネジ軸と、 該ネジ に«力を ί¾Τる 植付,睡ケース内の とを別体に形成し、植付 βケースの外側で横送りネ ジ軸と とを 離させたものであるから、横送りネジ軸の麵時に 付睡ケースをその都度^ »する煩わしさなく、 ネジ軸のみの線な ¾ ^を可能 とさせて保守点検などのィ樓性を向上させることができるものである。  The present invention provides a lateral feed screw shaft for laterally feeding a seedling mounting table, and a planting and a sleeping case that apply a force to the screw, and the lateral feeding screw shaft is formed outside the planting β case. Since the shaft and the shaft are separated from each other, it is possible to perform maintenance such as maintenance and inspection by making the line of the screw shaft only possible without the trouble of putting the sleeping case on each time when the side feed screw shaft is turned. It can improve the quality of the house.
