摘要
【目的】针对马铃薯种薯外形尺寸差异性较大、种薯的种皮种芽易受损伤而感染病毒的问题。设计了一种气力式水平圆盘马铃薯排种器.【方法】该排种器利用间歇输种与气力排种相结合的方式来提高排种性能,降低伤种率.【结果】阐述了排种器的工作原理,并确定了排种器的主要结构和性能参数,同时分析了排种盘、间歇式输种装置及拖拉机三者的速度关系.【结论】该排种器能有效解地决马铃薯播种机具因碰撞和挤压造成的机械损伤问题,也为大粒径种子的播种提供了一个新方法.
【Objective】Aimed at the large differences in potato shape and the problems of being vulnerable to virus infection due to easily damaged seed coats and buds,apneumatic metering device with horizontal disc for potatoes was developed.【Method】The metering device improve the performance by combining intermittent deliver seed with pneumatic seed discharging and reduced the percent of damaged seed.【Result】The operational principle of the seed metering device was expounded,and determined the main structure and performance parameters of the metering device,and the speed relationship among seed metering plate,intermittent seed conveying device and tractor was analyzed.【Conclusion】The seed metering device can effectively solve the mechanical damage problem caused by the collision and extrusion of the potato planter,and provide a new method for seed sowing with large diameter.
