中文摘要:气吸振动盘式精密播种机工作过程中,种子盘中的种子不断减少,吸种高度也相应减小。通过试验,结合水稻芽种物理特性,得出了种子量变化规律;提出吸种高度的控制方法,确定定量加种装置的加种量和加种周期,并进行播种试验。试验结果表明,吸种高度控制方法和定量加种控制方式使种子盘内种层厚度保持在8~18mm,吸种盘吸种率达到94%,能够满足播种机的精密播种要求。

Abstract:During the operation ofsuction-vibration precision seeder, the seeds on the tray were reducing continuously and suction height was declined accordingly. Through the experiments, combining with physical characteristics of rice seeds, the law of quantitative change for these seeds was obtained. A control method of suction height was proposed. Moreover, the quantity and cycle of the seeds-adding device were determined and seeding tests were conducted. The results showed that the seed-suction height control method and the seeds-adding control mode could make the seeds-layer thickness range at 8~18mm, and the absorbing rate of the seeds-suction could arrive at 94% or more, which was able to meet the requirements of precision seeding seeder.

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.
