4.5 m矮盘式秸秆饲料收获机割台的设计

Design of a 4.5 m Low-tray Straw Feed Harvester Cutting Table

针对国内秸秆饲料收割机械割幅小、适应性较差、收获效率低、可靠性差等问题,通过三维实体建模技术设计了4.5m矮盘式秸秆饲料收获机可折叠割台。该割台由变速器、折叠装置、分禾器、喂入滚筒和切割器等组成,利用折叠装置可实现4.5m宽幅割台的折叠运输,同时提高了割台的收获效率;割台专用变速器实现了同轴不同转速的输出,提高了割台传动系统的可靠性和紧凑性,对国内4.5m以上大割台的设计具有重要的参考价值。

Aiming at the problems of small amplitude, poor adaptability, low harvesting efficiency, and poor reliability of domestic straw forage harvesting machinery, a 4.5 meter short dish type straw forage harvester collapsible cutting table was designed through 3D solid modeling technology. The header consists of the transmission, the folding device, the branching device, the feed roller and cutters. The folding device can realize the folding and transportation of a 4.5-meter-wide header and improve the harvesting efficiency of the header. The transmission realizes the output of different coaxial speeds, improves the reliability and compactness of the header transmission system, and it has important reference value for the domestic design of large headers above 4.5 m.
