中文摘要:针对夹苗式水稻钵苗移栽机构取苗易失败,以及推秧爪推秧不充分影响钵苗直立度等问题,根据水稻钵苗移栽机构的工作要求,提出了一种夹钵式水稻钵苗移栽机构。基于Visual Basic 6.0开发了移栽机构辅助分析优化软件,分析了主要参数对移栽轨迹的影响,通过人机交互方式得到了一组满足移栽工作要求的机构参数。根据得到的机构参数,完成移栽机构的结构设计,进行了移栽机构的虚拟仿真分析,验证了移栽机构理论设计的正确性。设计了水稻钵苗移栽试验台并进行了移栽机构取苗试验,移栽机构回转速度设定为50r/min时,平均取苗成功率为93.06%,当转速为80r/min时,平均取苗成功率为88.89%,取苗成功率随着转速的提高而降低。研究表明,该机构具有较高的取苗效率和取苗成功率,可应用于水稻钵苗移栽机。

Abstract:In order to solve the problem of failure on clipping-seedling type transplanting mechanism of rice plug-seedling during seedling pick-up and not fully push-pull pushing that affect the upright degree of seedling, according to the design requirement of rice plug-seedling transplanting mechanism, a kind of clipping-plug type transplanting mechanism of rice plug-seedling was proposed. Firstly, according to the kinematic model of transplanting mechanism, an auxiliary analysis and optimization software of this kind of rice potted-seedling transplanting mechanism was independently developed with Visual Basic 6.0, and the influence of main parameters on the transplanting trajectory was also analyzed by the software. With the method of human-computer interaction based on visualization, a set of structural parameters satisfying the transplanting requirements was carried out. Then, according to the optimized parameters of mechanism, the overall structural design of the transplanting mechanism was completed. The correctness of the theoretical model and design of the transplanting mechanism was verified by the virtual simulation analysis of the transplanting mechanism. Finally, the test-bed for rice plug-seedling transplanting was designed, on which the seedling experiment of the transplanting mechanism was carried out. When the rotational speed of the transplanting mechanism was 50r/min, the average success rate of seedling pick-up was 93.06%, which was decreased with the increase of rotational speed. When the rotational speed was 80r/min,the average success rate of seedling pick-up dropped to 88.89%. It was showed that the mechanism had high seedling transplanting efficiency and high seedling success rate, so it can be applied to rice plug-seedling transplanting machine.

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.
