小麦免耕播种机浮动支撑式防堵装置

Floated Support Anti-blocking Device of Wheat No-till Seeder

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%。

Abstract:

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-covering, 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.
