2BHG-160型花生播种机关键部件设计与试验
Design and experiment of the key components of 2BHG-160 peanut planter
摘要
Abstract
In response to the problems that current peanut seeders has difficult to adapt to the working environment of clay loam soil in Southern China and can only be used for a single variety,an universal rotary tillage high ridge single seed seeder was designed in this study.Based on the agronomic requirements of peanut seeding,theoretical analysis and design were conducted on the key components of the seeder.In order to select a seed metering device that could be suitable for multiple peanut varieties,the main peanut varieties'Silihong'and'Xianghua'planted in Southern China were used as experimental objects.The type of seed metering disc and the speed of the seed metering shaft were taken as experimental factors,and the seed spacing qualification index and the damage rate were taken as evaluation indicators.Single factor bench tests were conducted based on the JPS-12 type seed metering performance test bench,and 2BHG-160 rotary tillage high ridge single seed seeder prototype was trail produced and field experiments were conducted.The results of the bench test showed that the optimal type of seed tray for sowing'Silihong'and'Xianghua'was the large seed tray,and the optimal seed axis speed was 10 r/min.The field test results showed that the qualified index of grain spacing between'Silihong'and'Xianghua'were 94.04 and 93.22,and the damage rates were 0.14％、0.62％,respectively.The qualified rate of the seeding depth of the whole machine,the ridge stability coefficient,and furrow stability coefficient were 84％,96.69％,and 95.47％,respectively.In conclusion,the machine designed in this study has good performance and can be used for peanut sowing in the southern clay loam environment.关键词
