Summary:钵苗移栽具有提高产量,增大精品粮种植面积等优点,该文作者基于双曲柄五杆水稻钵苗移栽机的结构形式,针对重要传动部件进行改进,开发了基于B样条拟合曲线的轻简化水稻钵苗移栽机构——拟合齿轮五杆水稻钵苗移栽机构。对该机构进行拟合齿轮节曲线传动分析,建立移栽机构运动学模型,运用matrix laboratory(MATLAB)中GUI平台开发出了水稻钵苗移栽机构辅助分析与参数优化软件,通过软件优化得出一组能够满足钵苗移栽要求的结构参数。建立三维模型,并通过automatic dynamic analysis of mechanical systems(ADAMS)进行虚拟样机仿真,初步验证机构的合理性。加工移栽机构核心部件,装配并在试验台架上进行试验研究。通过对移栽机构的试验台架试验,验证了移栽机构参数的合理性和有效性。以秧夹开口开度、秧夹夹持力、取秧频率为因素,以伤秧率和漏秧率为评价指标,选取二次回归正交旋转组合试验的方案,运用Design-Expert 7.0软件进行分析,得到的分析结果进一步验证了拟合齿轮五杆移栽机构的合理性。

Pot seedling transplanting has the adva ntages of increasing the production, enhancing the fine grain planting area, and so on. The rice pot seedling transplanting will have a good prospect in the future, but at present the application of rice pot seedling transplanting machine is less in China. Since Japan invented the first transplanter for rice pot seeding in1900 s, large agricultural machinery companies have produced their own models in succession, such as Yanmar and Iseki.The materials and manufacture technologies have been improved through about 40 years' development, but the basic structure and working principle are still kept at the same level. All the transplanting machines use 3 sets of mechanism to complete 3 kinds of movements i.e. picking, transporting and planting. The existing machines have the disadvantages of complex structure, high cost and low efficiency. In order to further improve the rice seedling transplanting quality, the transmission changes with the B spline fitting noncircu
