精量点播机种类和机型繁多,结构不一,工作过程也不同,但都必须满足农艺对播深、株距、垄距、播量等播种质量的技术要求,所以作业必须要进行以下两项工作。精量点播机作业前的检验牵引拖拉机需完全满足精量点播机对动力机械的技术要求,点播机机架不变形,播种部件(开沟器)的底刃在同一水平线上、相差不超过±2.5毫米,各播种单体圆盘开沟器转动灵活、不摆动、摆差小于8毫米,开沟器盘不摆动、摆差小于5毫米。各播种单
There are many types and models of precision juicer, different structures and different work processes, but all must meet the technical requirements of sowing quality such as sowing depth, spacing, ridge spacing and sowing rate. Therefore, the following two items must be carried out jobs. Precision on-demand inspection of pre-job Tractor tractors to be fully met the precision on-demand machine on the technical requirements of power machinery, on-demand machine frame deformation, sowing parts (opener) the bottom edge of the same horizontal line, the difference does not exceed ± 2.5 mm, each sowing Monomer opener rotation flexible, non-swinging, swing less than 8 mm, opener disk does not swing, swing less than 5 mm.
