2TYB-450型水稻田间育秧播种机的设计

摘要

According to the requirements of rice seedlings in field, 2TYB-450 rice seeder for seedlings in field was designed with synchronizing wheel and mechanical vibration. The experiment results showed that the eligible ratio was 66.2% and the hole ratio was 3.8% when every hole(the area was 1.96 cm2) needed 3-7 grains. It could satisfy the agricultural requirements of rice seeding in field.%针对水稻田间育秧播种的要求,设计了同步驱动轮与机械振动排种相结合的2TYB-450型水稻田间育秧播种机,试验结果表明:以取秧面积为1.96 cm2、3～7粒/取秧面积为合格时,播种合格率为66.2%,空穴率为3.8%;且排种稳定性较好,能够满足水稻田间育秧播种的农艺要求.
