摘　　要：通过高速摄像技术观察了穴盘水稻秧苗通过分秧滑道的情况,发现滑道上部的过渡圆弧段是影响秧苗通过性的关键,其中分滑道1～3的通过性相对于其他分滑道要差;当秧苗营养土含水率为26.6%时,秧苗通过整条滑道的时间比营养土含水率为31.2%时的要短,且与计算机虚拟仿真的结果更接近。试验结果表明,秧苗通过分滑道1所用的时间最长,通过分滑道6所用的时间最短,秧苗在各分滑道中下滑的一致性较好,所设计的分秧滑道能够满足机械手式抛秧机中对分秧作业的要求。The process of rice seedlings passing through the separating chutes was observed using high speed photography technology.The circular arc part of chutes was the key that affects the rice seedlings passing through chutes.It was easier for rice seedlings to pass chute No.4~7 than No.1~3.The time of rice seedlings passing through chutes was shorter and closed to simulation results calculated by computer when water content of nutrient soil of rice seedlings was 26.6%.It need the longest time when rice seedlings pass through chute No.1.The shortest time appeared when rice seedlings passing through chute No.6.The results of experiment showed that chutes of separating rice seedlings could be satisfied the requirements of throwing transplant machine for rice seedlings sprouted in the plastic cell-tray.
