悬挂播种中耕通用机的研制在我国仅有十几年的历史。此种机具利用同一机架,通过变换不同的工作部件,来完成多种作物的播种、中耕及起垅等项作业,具有一机多用的特点。它比单一作业机利用率高,节省钢材。同时,适应性较强、调节范围大,对间套作有一定的适应性。通用机架的出现,为实现我国北方早作地区农业机械化增添了一种重要的机具。但随着我国农业机械化的发展,新型号的拖拉机不断出现,现有的通用机架已不能满足配套的需要。此外原机还存在着
Suspension sowing cultivated general-purpose machine in our country only a dozen years of history. Such machines using the same rack, through the transformation of different working parts, to complete a variety of crops sowing, cultivation and plowing and other operations, with a multi-purpose machine features.
