近年来,谷物联合收割机保有量快速增长,收割面积逐年增加。但是,联合收割机故障一直居高不下,在很大程度上影响了收割进度和经济效益,这与机手在联合收割机使用前的技术检查不充分有很大关系。因此,联合收割机使用前必须进行以下几项技术检查与调整。 In recent years, the number of cereal combine harvesters has increased rapidly and the area harvested has been increasing year by year. However, the failure of combine harvesters has remained high, greatly affecting the harvesting schedule and economic benefits, which is largely related to the inadequate technical inspection of the combine prior to use. Therefore, the combined harvester must be used before the following technical inspection and adjustment.
