中文摘要:针对现有中小农户大棚蔬菜穴盘栽培手工播种生产率低、劳动强度大等问题,以及国外大型播种机不适合我国中小规模种植经营户需求的现状,设计了一种应用于大棚栽培的穴盘自动化便携式播种机。该播种机一端可折叠,折叠后尺寸为500mm×500mm×750mm,携带方便;播种机采用多功能集成化设计,将传统的穴盘打孔、播种集成于一体,通过激光传感器检测穴盘凹口位置,准确地实现了穴盘基质的自动打孔和播种。经油菜种子和黄瓜种子试验表明,当孔径处于0.6~1.2mm时,选择真空度为8kPa,吸附效果较好;若选用0.6mm孔径气吸吸头,当油菜种子气吸真空度超过6.2kPa,以及黄瓜种子真空度超过8.3kPa时,吸附成功率达到90%以上。经正交试验,发现油菜种子和黄瓜种子在孔径为0.6mm,真空度为10kPa时吸附效果最好。与手工播种相比,播种机播种效率是手工播种效率12.9倍,较好地实现了蔬菜种子的穴盘播种。

Abstract:With the development of specialization and large-scale vegetable planting in China, factory seeding was widely used, and there was high requirement for sowing. Vegetable tray seeding machinery is one of the core equipment of vegetable seedling. In order to solve the problems of low productivity, high labor intensity in manual seeding and the current planting machine being not suitable for the need of small and medium sized planting greenhouses in China, the automatic seeding device used in greenhouses was designed on the base of the analysis of characteristic parameters of rape and cucumber seeds. One side of the seeding device can be folded in order to carry it easily. The size of folded seeding machine was 500mm×500mm×750mm.The device was designed with a multifunctional integrated structure, including hole-punching and seeding, which simplified the working procedure. Both the hole-punching and seeding can be achieved accurately through detecting the position of the notch in the tray by laser sensor. The success rate of seed adsorption was an important factor of seeding machine. The success rate of adsorption would directly affect the success rate and production efficiency of seeding machine. Experimental results showed that the size of suction head had effect on suction success rate when pressure was decided. The suction success rate was high when the diameter of suction head was within 0.6~1.2mm and the vacuum degree was 8kPa. Selecting the diameter of 0.6mm,the success rate reached over 90% when pressure was higher than 6.2kPa for rape seeds and 8.3kPa for cucumber seeds. By orthogonal experiment, it was found that the best adsorption effect was with vacuum degree of 10kPa and diameter of 0.6mm. Compared with manual seeding, the efficiency of seeding machine was improved by 12.9 times. The research provided a new structure and design idea to solve problem in seeding.

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.
