    摘要:

    為深入研究種子玉米脫粒特性和脫粒損傷機(jī)理,改進(jìn)玉米脫粒機(jī),降低脫粒損傷,,提高脫粒效率,,以隆迪401玉米種子為對象,,應(yīng)用LDS微機(jī)控制電子拉壓試驗(yàn)機(jī)等進(jìn)行了脫粒試驗(yàn),研究了玉米種子品種、含水率,、作用部位及不同約束性質(zhì)下的種子玉米脫粒力學(xué)特性,。結(jié)果表明:在同樣試驗(yàn)條件下,,玉米穗大端籽粒脫粒較容易,小端次之,,中部較難,;縱向彎曲力小于側(cè)向彎曲力,側(cè)向彎曲力小于壓力,;種子玉米脫粒時(shí)的最佳施力方式為縱向彎曲力,。

    Abstract:

    In order to research threshing seed-corn identity and damage mechanism, improve threshing principle, reduce damage and enhance efficiency, the threshing experiments for Longdi401 seed-corn were carried out by using the LDS microcomputer control and electron draw press test machine, to investigate the effects of variety , moisture condition, force position and restriction property. The results show that under the same condition, it's easiest at corn bottom fringe to thresh, the second is at top fringe and the last is middle fringe; the longitudinal bending force is the optimal forcing method for threshing. 
