脚踏式玉米播种机的设计与试验

Design and Experiment of Stampede-style Maize Seeder

针对北方播种玉米的垄作区内存在一些狭长或凹凸不平的特殊地块,设计了一种便携式脚踏玉米播种机,包括支撑底座、踏板、前推杠杆及排种装置,通过支撑底座与踏板的相对运动,实现排种装置的排种。田间试验结果表明:当垄宽分别为350、380、400mm时,株距误差分别为7.44%、5.13%、1.91%,播种深度合格率分别为95.14%、92.1%、89.72%,测试误差符合要求,脚踏式玉米播种机的设计能够满足特殊地块的耕种需求。

To solve the problems of the North Ridge sowing maize area exists in Narrow or uneven of the special region,a stampede-style maize seeder was designed.The seeding machine comprises a supporting base,apedal,push lever and Sowing mechanism.Through the relative movement of the support base and the pedal,planting with sowing machine.The result of field tests showed that in row spacing was respectively 350mm、380mm and 400 mm,and plant spacing error were 7.44%,5.13% and 1.91%,sowing depth qualified rate were 95.14%、92.1% and 89.72%.The design of stampede-style maize seeder satisfied the agronomic requirements.
