高通过性四轮自走式烟草田间作业机的设计

针对烟草中后期田间管理迫切需要高通过性动力机械的现状，通过采用拱桥式车架，偏置布置在拱桥式车架一侧的发动机及传动系统，架高转向横拉杆及过桥传动轴等结构措施，设计出高通过性的四轮自走式烟草田间作业机，其最大通过高度1700?mm，变速范围1.0～18?km/h，解决了烟草田间作业动力机械高通过性的技术难题。该机自身可实现植保作业，若悬挂不同的机具可实现耕地、起垄、移栽、铺膜、中耕培土、打顶、采摘烟叶、拔烟秆等多种作业。小批量生产试验表明，该机驾驶劳动强度小，通过性好，对烟叶损伤小，作业效率高。

Design of high trafficability four wheel self-propelled field machine for tobacco

In accordance with the need of high trafficability field machinery of field management for tobacco in the mid and late stage,a four-wheel self-propelled high trafficability field machine was designed, which included an arch chassis with engine and transmission arranged on one side. Its maximum trafficable height is 1 700 mm, with the speed range from 1.0 to 18 km/h. Combined with different tools, the machine can be used for various kinds of field works, such as protecting plants, cultivating lands, ridging, transplantation, mulching film, cultivation and banking, topping, picking tobacco, uprooting the cigar pipe. Field test with the prototype proved that it had the characteristics of little working intensity, high trafficability, low losses of tobacco, and high working efficiency.
