播种机播完种后,排肥机构的零件,如排肥轮阻塞轮等沾满了肥料、尘土等污物。对这些污物如不马上清除,将直接影响着零件的使用寿命。为了清除这些污物,我们曾采用过砂纸磨,锉刀锉及用水泡,洗等方法,但效果都不理想。 After sowing the sowing machine, the parts of the fertilizer making unit, such as the obstruction wheel of the fertilizer wheel, are covered with dirt such as fertilizer, dust and the like. If these stains are not removed immediately, will directly affect the service life of parts. In order to remove these contaminants, we have used sandpaper, rasp files and blisters, washing and other methods, but the effect is not satisfactory.
