中文摘要:超级稻育秧精密播种器中的精密播种部件采用气吸滚筒和振动种盘的组合方式来控制精确吸种,种盘供种区域内种子的“沸腾”状态和蠕动状态均与振动参数密切相关。本文结合供种区域不同的种层厚度以及气动振动器的不同安装位置测试了滚筒的吸种效果,并探讨了超级稻育秧精密播种器中种盘振动特性对滚筒吸种效果的影响。试验结果表明, 激振源安装在种盘后方对播种精度最为有利,种层厚度为0.7cm、振动频率为98Hz时吸种效果最佳,其合格率达93.118%。

Abstract:The performance of fine-sucking seed was controlled by the combination mode of the vacuum cylinder (VC) and the vibrating seed plate (VSP) in the precision seedling planting parts for super hybrid rice. The ebullience and vibration of the seed close to VC in VSP were highly correlated with vibration parameters. The sucking-seed capability of VC was measured on conditions of the different seeds thickness and the installation position of vibrator, respectively. In addition, the vibration characteristic of VSP was studied. The results showed that the optimal performance is obtained when the air-style vibrator is at the rear of VSP, and the regular capability of fine-sucking seed depends on the given seeds thickness close to VC and the vibrator’s frequency in harmony. The prime performance comes to 93.118% when the optimum seeds thickness 0.7cm and frequency of vibration 98Hz.

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.
