摘  要：
针对黄淮海一年两熟地区小麦机收后地表残留的秸秆量大且根茬过高,致使免耕播种下茬作物时易发生堵塞的现象,设计了一种用于麦茬地免耕精播机的防堵装置。为确定该装置合理的结构与作业参数,采用三因素三水平正交试验方法进行了优化试验,得到最优参数组合:机组作业速度4.5 km/h、清秸覆秸刀齿排布4-3-4、刀轴转速400 r/min。田间试验结果表明,当清秸覆秸刀齿切茬深度为20～30 mm时,防堵装置土壤扰动量为63%～76%,防堵效果好,能够创造良好的种床,提高播种质量。

摘  要：
A type of anti-blocking mechanism,used on no-till precision planter for wheat stubble fields,was designed.The purpose was to solve straw burning and residue blocking between seeding units which were caused by large amount of straws and higher stubbles in annual double cropping area of Huanghuaihai.In order to find out reasonable structure and operation parameters of the anti-blocking mechanism,optimization experiment was conducted with orthogonal test method of three factors and three levels.The optimal parameters combination was as follows: the operation speed of 4.5 km/h,the arrangement of blade of 4-3-4,the rotating speed of blade shaft of 400 r/min.The field experiment result showed that when the cutting depth of blade was 20~30 mm,the soil disturbance was 63%~76%,the anti-blocking mechanism could solve the problem of straw blocking and improve the seeding quality.
