红壤丘陵区小型花生播种机的设计和试验研究

摘要

根据江西红壤丘陵区花生种植的特点，设计了以4～6 kW柴油机为动力，采用窝眼轮式排种器、链条传动的小型花生播种机。通过室内和田间性能测试，该播种机的播种行距、株距、播种深度、漏播率、种子破碎率等技术指标基本上能满足花生播种的要求。%According to the features of peanut planting in red soil hilly region of Jiangxi , the author developed and designed a small-size peanut planter with socket-roller seeding device , which used 4~6 kW diesel engine as power and was driven by chain . The results of indoor and field performance tests showed that some technical indexes ( such as seeding line spacing , seeding plant distance, seeding depth, miss-seeding rate, and broken seed rate) of this planter could basically meet the demand of peanut so-wing.
