据对农机专业户实际调查资料的统计分析,得出12马力(8.83 kW)手扶拖拉机的故障率服从对数正态分布,平均可靠使用期耗油为518 kg;农机专业户的经营收入,随着可靠使用期的延长而提高,每增加或减少1kg耗油的使用期,经营收入即增加或减少1.45元。为了延长机器的可靠使用期,增加农机专业户的经营收入,必须提高驾驶员素质,按规程保养维修,加强管理,健全维修系统,采取有效措施,限制农业机械的盲目发展,并应对农机专业户加强指导。
According to the statistical analysis of actual survey data of specialized agricultural households, it is concluded that the failure rate of 12-horsepower (8.83 kW) walking tractors obeys log-normal distribution and the average reliable usage period fuel consumption is 518 kg. The operating income of agricultural specialized households, with Reliable use of the extension of the increase, for every increase or decrease the use of 1kg fuel consumption, operating income that increase or decrease 1.45 yuan. In order to prolong the reliable service life of the machine and increase the operating income of the specialized agricultural machinery industry, the quality of the driver must be improved, the maintenance and repair of the driver should be improved, the management and sound maintenance system should be strengthened, effective measures should be taken to limit the blind development of agricultural machinery, and the guidance of specialized agricultural machinery dealers should be strengthened. .
