中文摘要:为了实现将水稻钵苗移栽和膜上栽植农艺技术相结合,设计了相应的步行式水稻钵苗膜上开孔移栽机构,用一套回转机构一次性依次完成取苗、输送、膜上开孔和配合栽植。根据移栽机构的工作原理,建立了运动学理论模型并设定数字化优化目标,基于Visual Basic 6.0开发了机构的计算机辅助分析优化设计软件,通过优化获得一组满足移栽要求的机构参数。对机构进行了结构设计、三维建模和装配,并通过ADAMS软件完成了虚拟样机仿真,应用3D打印技术制作了物理样机。利用高速摄像技术在所搭建的试验台架上对样机进行了轨迹与姿态验证试验,通过对比分析得到理论轨迹、虚拟仿真轨迹和物理样机轨迹基本一致,验证了机构设计的合理性与正确性。在试验台架上完成了取苗试验、膜上开孔试验以及栽植试验,结果表明取苗成功率为90.4%,秸秆纤维地膜和塑料地〖JP2〗膜栽植成功率分别为87.5%和82.5%,所开膜孔的长度与宽度效果良好,满足步行式水稻钵苗膜上开孔移栽的要求。

Abstract:In order to achieve the combination of potted rice seedling transplanting and technology of mulch film, a kind of walk type potted rice seedling transplanting mechanism was designed. The process of seedling picking, conveying, film perforating and cooperating transplanting was completed by a set of rotary mechanisms. According to the working principle of the transplanting mechanism, kinematic theory model was set up and digital optimization goals were set. The computer aided analysis and optimization software of the transplanting mechanism based on Visual Basic 60 was developed. A set of parameters of the transplanting mechanism which met the requirements of transplanting were obtained by optimization. The two dimensional structure of the transplanting mechanism was designed. Three dimensional model was established. The virtual prototype simulation was completed by ADAMS software. The trajectory and attitude verification tests were carried out on the prototype using the test bench and high speed photography technology. The results of bench test, simulation analysis and theoretical analysis were almost in agreement, which verified the rationality and correctness of the institutional design. The seedling pick up test, film perforating test and transplanting test were completed on the test bench. The results showed that the success rate of seedlings pick up was 90.4%. The success rate of transplanting for films of straw fiber and plastic was 87.5% and 82.5%, respectively, the results showed that the length and width of the film holes were good, which could meet the requirements of walk type potted rice seedling transplanting mechanism on film perforating part.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
