播种机的双圆盘开沟器是由内外锥体组成支承。通过增减调整垫圈,与圆盘毂形成适当间隙。当内外锥体和圆盘毂严重磨损后,调整垫圈全部取去,间隙还是过大,能常应更换新锥体或圆盘毂。本着勤俭节约的原则,我们把内锥体磨修后重新使用,效果良好。修磨的方法是:把内锥体在砂轮上磨去2～3毫米;一般磨至与原油槽平为宜,然后再用 The planter’s double disk opener is composed of inner and outer cones. Adjust the washer by increasing or decreasing to form an appropriate clearance with the disc hub. When the inner and outer cones and disc hubs are heavily worn, the washers are completely removed and the clearance is still too large. New cones or disc hubs should frequently be replaced. In the principle of diligence and frugality, we re-use the cone after grinding, the effect is good. Grinding method is: the cone on the grinding wheel worn to 2 to 3 millimeters; general grinding and crude oil tank level is appropriate, and then reuse
