摘要: 针对现有油菜割晒机铺放质量差,导致后熟时间不可控、后续捡拾损失大的问题,设计了4SY-2.2型油菜割晒机,可实现油菜的分禾、切割、输送和铺放作业。对油菜茎秆在铺放台上和离开铺放台的运动过程进行分析,给出了油菜茎秆能顺利被推送、抛出铺放台的条件,对油菜茎秆离开铺放台后的运动分析可知,油菜的铺放角与油菜本身的生物学特征、割晒机的结构参数和割晒机的运动参数有关。田间试验表明,割晒机作业后形成的油菜铺条整齐性和一致性较好,测得铺放角平均值48.4°,铺放厚度平均值511.6mm,铺放宽度平均值797.8mm,割茬高度平均值365.5mm,铺放质量满足后熟条件和后续捡拾的作业要求。

Abstract: Aiming at the low quality of rape straw laying, which could result in the uncontrollable afterripening and great lost of pick- up value, the 4SY- 2.2 rape windrower was designed to achieve dividing, cutting, conveying and laying operation. The authors analyzed the movement process of rape straw on and out of the cutting platform, and then determined the essential condition for smooth convey and cast of rape straw. The analysis of the movement curve of the dropping rape straw showed that the rape laying angel was related with its own biologic characteristics, windrower structural parameters and motion parameters. Field experiments showed that the laying of rape was orderly after windrower operation, the average value of laying angel was 48.4°, the average layer height was 511.6 mm and the width was 797.8 mm, the average height of the cutting stubble was 365.5 mm. It indicated that the laying quality could reach the requirement of after-ripening and pick-up operation.
