近年来,由于农业技术的发展,大大提高了拖拉机的利用率。现在拖拉机下水田作业项目日渐增多,如用铧犁耕水田,旋耕机旋整水地,水田机平地,机械抛秧等。拖拉机下水田作业应注意些什么呢? 1.作业前,要对作业地进行实地勘查,对新填平的沟、塘等位置作好标记,避免作业时陷车和伤人。 2.作业前,应对主副机进行认真保养,做到各部件紧固可靠、调整恰当,保证操作有效。特别要检查有可能浸水部位的油封是否良好,并换上耐温耐水的润滑脂(钙基、锂基),以保证即使水渗入轴承后,润滑脂也不会随水
In recent years, due to the development of agricultural technology, greatly increased the utilization rate of tractors. Tractor now under the paddy field operations are increasing projects, such as using plow tillage paddy field, rotary tillage rotary water machine, paddy land, mechanical throwing seedlings. Tractor under paddy field operations should pay attention to what? 1. Before the job, to conduct field surveys on the job site, the newly filled ditches, ponds and other locations marked to avoid work trapped and wounding. 2.Operation before the main and auxiliary should be carefully maintained, so that the various parts of the fastening reliable, appropriate adjustments to ensure that the operation is effective. In particular, it is necessary to check whether the oil seal at the site of immersion is good and replace the grease with heat and water resistance (calcium-based, lithium-based) to ensure that the grease will not follow the water even after the water has penetrated into the bearing
