摘　　要：针对我国华北一年两熟区秸秆量大,根茬粗,免耕播种机开沟器前易产生壅堵,影响机具通过性能和播种质量等问题,设计了一种浮动支撑式防堵装置,阐述了其工作原理,设计了主要工作部件,确定了其结构参数,并进行了田间性能试验。试验结果表明:安装有浮动支撑式防堵装置的小麦免耕播种机通过性能良好,符合农艺要求;与带状旋耕防堵装置相比,土壤扰动量减少约25%,油耗降低约7.04%。In order to solve the problems of wheat no-till seeders in annual double cropping area of North China Plain such as large amount of straw-coveting, stubble-bulky, residue-blocking, and bad passing capacity and planting quality, the new anti-blocking device using floated support was designed. This paper elaborated the working principle. Major working parts of the anti-blocking device were designed, and the structure parameters were determined. The field experiment showed that the no-till planter with floated support anti-blocking device had good passing capacity. Compare with strip-rotary anti-blocking device, floated support anti-blocking device reduced soil disturbance and oil consumption by 25% and 7.04% respectively.
