近年来,随着农村经济的发展,愈来愈多的手扶拖拉机从事农村短途运输作业,据有关统计,手拖运输作业量占总作业量的60～80%以上。然而手拖的结构形式主要是为田间低速作业考虑的,它不适用于高速的运输作业,因此容易发生事故。我们通过调查和分析发现: 1.拖拉机事故是农机事故的主要组成部分。 2.拖拉机事故主要发生在运输作业时,如浙江省1980年有77%发生在公路运输时,江苏近几年有70%是运输作业事故。
In recent years, with the development of rural economy, more and more walking tractors are engaged in short-distance rural transport operations. According to relevant statistics, the handling volume of trolley transport accounts for more than 60% to 80% of the total workload. However, the structure of the towbar is mainly considered for low-speed operation in the field. It is not suitable for high-speed transportation and is therefore prone to accidents. Through investigation and analysis, we found that: 1. Tractor accidents are the major components of agricultural accidents. 2. Tractor accidents occurred mainly in transportation operations. For example, in Zhejiang Province, when 77% of road traffic took place in 1980, 70% of Jiangsu’s accidents occurred in transport operations in recent years.
