近几年来,随着农村各项经济政策的落实,为适应广大农民发展农村商品经济的需要,一些工厂在研究设计部门的帮助下,设计、生产了不同类型,不同吨位的中小型农用运输车。这些车,一般都是采用手扶、小四轮拖拉机配套的柴油机为动力,配件通用化程度高,结构简单,布局紧凑,价格不高,好用好修。目前,农村中主要运输机械以手扶、小四轮拖拉机为主。而拖拉机的设计是以耕作为主的。特别是手扶拖拉机,上下坡反向操作,用于运输,安全性差,工作条件差,而且油耗高。目前,我国道路条件差,三、四级公路多,农村大多是机耕道,路面窄,弯道多,路面不
In recent years, with the implementation of all economic policies in rural areas and in order to meet the needs of farmers for developing rural commodity economy, some factories, with the help of research and design departments, have designed and produced small and medium-sized farm vehicles of different types and sizes . These cars are generally powered by hand-held, small four-wheel tractors supporting the diesel engine as a power unit, a high degree of generalization of accessories, simple structure, compact layout, the price is not high, easy to use good repair. At present, the main transport machinery in rural areas is mainly hand-held and small four-wheel tractors. Tractor design is based on farming. In particular, walking tractor, up and down the reverse operation, for transport, poor security, poor working conditions, and high fuel consumption. At present, the road conditions in our country are poor. There are many highways of Grade 3 and 4. Most of the rural roads are tractor-mounted roads with narrow pavements, many corners and no pavement
