    摘要:

    根据油菜收获的农艺要求,针对油菜人工收获效率低下和联合收获损失较高的情况,设计了一种实现油菜分段收获的4SY-1.8型油菜割晒机,确定了该机的主要结构和工作过程,进行了输送系统、分禾装置和切割装置等关键部件的结构设计与参数分析。研制的集成伸缩滚筒、立辊和输送带构成的输送系统,可实现油菜茎秆铺放宽度约为1 000 mm的中间纵向条铺;同时,利用液压装置控制割茬可调高度为200~450 mm。验证试验结果表明,所研制的油菜割晒机结构合理,能满足油菜分段收获的要求,达到有效延长油菜收获期、减低油菜损失率并提高油菜生产效益的目的。

    Abstract:

    A rape windrower was designed. The main structure and the working process of the machine were determined,including the structure design and the analysis of the key components such as the convey system, the separating system and the cutting device. A kind of convey system, which included telescopic cylinder, vertical cylinder and conveyor was designed and it could achieve the middle of the vertical placement of 1 000 mm. The cutting height can be adjusted to 200-450 mm by hydraulics equipment. The rape windrower can meet the requirement of segment harvest and was designed reasonably through experimental verification. It can extend the harvest season of rape effectively, which can not only reduce the loss rate of rape but also increase the economic efficiency.
