轮式自走联合收割机结构复杂,作业环境恶劣,操作技术难度大,不安全客观因素多。随着联合收割机保有量的增多,小麦和水稻跨区收割气候的日益形成和发展,联合收割机安全事故率也呈上升趋势,其中人为因素造成的安全事故占相当的比例,为提高经济效益,避免或减少联合收割机作业中因人为工作不到位而可能 Wheeled self-propelled combine harvester complex structure, poor operating environment, operating technical difficulty, unsafe objective factors. With the increase of combine harvesters, the growing and development of wheat and rice cross-cutting harvester climate, the safety accident rate of combine harvesters has also been on the rise. Among them, man-made factors account for a considerable proportion of safety accidents, in order to increase economic benefits , To avoid or reduce the possibility of man-made work not being in place in combine harvester operations
