一、圆盤过松或过紧:对这个问题都知道加减垫圈就可以解决。但是有的两圆盤交点太大,容易产生播后沟间突起较宽,影响种子分布,盖土不良。遇到这种情况,如減少垫圈,圆盤就不转动了。可加半圈垫,垫的地方其方向是和交点对立的,这样不仅达到圆盤交点接触——最大间隙不超过0.5毫米(1毫米以内也行),而且转动灵活。关於过紧的,千万别光松螺母,有一次因为
First, the disc is too loose or too tight: on this issue all know that adding washers can be resolved. However, some of the two disk intersection point is too large, prone to broadcast wide gap between the ditch, affecting the distribution of seeds, covering poor soil. Encountered such a situation, such as reducing the gasket, the disc does not rotate. Half a lap pad can be added, where the pad is oriented opposite the intersection point so that not only does contact at the point of contact of the disc reach a maximum of 0.5 mm (less than 1 mm), but also with the flexibility of rotation. On too tight, do not loose pine nuts, once because
