| 摘 要： | 玉米收获机分禾器结构直接影响玉米植株的分禾和输送效果，是决定机具能否正常作业的重要因素。通过田间试验，对玉米植株抗弯特性进行了测定，测量出玉米植株的横向最大偏移量，并计算出玉米植株偏折角。得出了分禾器宽度与玉米植株抗弯特性之间的关系方程，找到了影响分禾输送效果的一个重要因素——植株自身的抗弯特性，为分禾器的设计提供了新的依据。在理论上解释了作业时分禾器离地越高越不易碰伤植株的现象，且对比了不同地区品种玉米植株抗弯强度的差异性，结论是最佳收获期内山东省、北京市地区品种的玉米植株抗弯能力比吉林省地区品种强。

| Abstract: | Corn harvester divider has a direct impact on maize seedling conveying, it is an important factor to influence the harvester operation. Corn straw physical property and max transverse offset distance were measured by experiment in corn filed and max offset angle was accounted. The relation equation between divider width and corn plant bending property was acquired by data process. An important factor on effecting dividing and conveying plants was found, that was the bending property of corn plants. A basis was provided for the divider design. It is interpreted in theory that the higher divider positioned the slighter the plants damaged. The difference between bending strength of different regional corn plants was compared and analyzed. In the optimum harvest period, corn plants resistance to bending in Shandong Province and Beijing regional was stronger than it in Jilin Province. |
