    摘要:

    針對玉米聯(lián)合收獲機的重要部件——玉米剝皮裝置通用性差等問題，設計了可更換不同輥型、調(diào)節(jié)轉(zhuǎn)速以及調(diào)節(jié)兩輥相對位置角的玉米通用剝皮機構。以先玉335為試驗材料，進行了剝皮輥配置形式、轉(zhuǎn)速和兩輥相對位置角的3因素3水平正交試驗，分析了各參數(shù)對剝皮性能：玉米苞葉剝凈率、籽粒破碎率、籽粒損失率的影響，確定了最優(yōu)組合方案：剝皮輥配置形式為螺旋橡膠輥與凸棱螺旋橡膠輥交替排列；剝皮輥轉(zhuǎn)速為350r/min；兩輥相對位置角為30°。

    Abstract:

    Corn husker is one of important parts of the corn combine harvester, it would affect the seed loosen ratio, the seed broken ratio and the bract no-husking ratio. Aimed to the problems of bad exchange, the universal corn husker was designed, which could exchange the roller type, adjust the rotate speed, and adjust the angle between the axis of husking roller and horizontal direction. Taking Xianyu 335 as an example, three factors were chosen as the husking rollers, the speed of the husking rollers and the angle, and each factor had three levels. The test data analysis showed that the best combination plan could be found out, the husking roller was alternating arrangement of the spiral rubber roller and spiral rubber roller with convex edge, the husking roller speed was 350r/min, and the angle was 30°.
