笔者驾驶操作联合收割机和运粮拖拉机10年有余,在工作过程中总结了一些经验,现略述两点如下。 (1)尽量做到边收获边卸粮。在收获作业中,有许多机手都是在联合收割机粮仓储满后停下来再往拖拉机挂车上卸粮。这样做既增加了油耗,又降低了收获效率。以SE514型联合收割机为例,粮仓储满后,每次卸粮开始到结束约需4min。在这过程中虽然收割部件停止了工作,但是发动机仍在运转。每个工作日卸粮如按20次计算, I operated the combine harvester and grain tractor more than 10 years, summed up some experience in the work process, are outlined below two points. (1) try to harvest while unloading grain. During the harvesting operation, many of the drivers stopped after the silos of the combine harvesters were unloading food from the tractor trailer. This not only increases fuel consumption, but also reduces harvesting efficiency. To SE514-type combine harvester, for example, after the granary is full, each unloading grain from the beginning to the end about 4min. The engine is still running although the harvesting unit stopped working during this process. Unloading grain every working day, such as according to 20 calculations,
