中文摘要:设计了一种能实现水稻秧盘育秧精密播种流水线硬、软秧盘自动叠放的装置,有效地提高了流水线的生产率,并减轻了劳动强度。该装置以可编程控制器PLC为控制核心,由接近开关检测待叠秧盘,控制秧盘升降机构实现秧盘升降的自动叠放,采用土壤防漏机构的气动移动盖板来防止秧盘内的土壤在叠盘过程中发生侧漏而使种子外露。为检测自动叠盘装置的工作性能,以叠盘成功率及种子外露率为指标,以秧盘升降机构的升降速度、盖板方式和生产率为影响因素,设计了三因素三水平正交试验。试验结果表明,升降速度对叠盘成功率影响较大,盖板方式和升降速度对种子外露率影响较大;当升降速度为0.15m/s、采用气动移动盖板和生产率为600~800盘/h时,硬、软秧盘的叠盘成功率分别为100%与99%~100%;硬、软秧盘的种子外露率最大分别为0.28%与0.60%,试验指标满足水稻秧盘育秧精密播种流水线育秧技术使用要求。

Abstract:At present, most of the work that taking trays out from the rice nursery seedling planter is completed one by one manually, which is labor intensive and inefficient. There are some tray stackers can realize the function of automatic stacking, but the existing devices are only suitable for hard trays. Aiming at above problems, the automatic tray stacking device of rice precision seeding for nursing seedlings pipeline, suitable for both hard and soft trays, was developed to improve productivity and reduce labor intensity. According to the characteristics of common hard tray, the pallet of soft tray was developed for stacking. Besides, the transportation mechanism was designed through analyzing the conveying model. Based on the programmable logic controller(PLC), the trays were detected by a proximity switch of the control system, and the tray stacking mechanism was controlled to lift and drop the trays to achieved the tray stacking automatically(2~4 trays per stack is available). In addition, the cover plate of the soil anti falling mechanism was controlled to lift after stacking and finally the device can effectively prevent the soil falling out of the tray in the process of stacking that lead to seeds exposed. For detecting the performance of automatic tray stacking device, the orthogonal experiment was carried out which regarded stacking success rate and seeds exposed rate as indexes and regarded the lifting speed of tray stacking mechanism, cover plate installation conditions and productivity as factors. Orthogonal experiment results showed that the lifting speed had more influence on success rate while the lifting speed and cover plate installation conditions had more influence on seeds exposed rate. When the lifting speed was 0.15m/s, the cover plate installing with pneumatic cylinder and the productivity was 600~800 trays per hour, the stacking success rate of hard tray and soft tray was 100% and 99%~100% respectively while the seeds exposed rate was 0.28% and 0.60% respectively. The automatic tray stacking device can effectively raise productivity and reduce labor intensity, and the experimental indexes meet the using requirements of rice precision seedling.

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.
