Compaction wheel of corn planter

The utility model relates to a compaction wheel of a corn planter, and belongs to the field of mechanical design and manufacturing. The whole compacting wheel is approximately cylindrical, the middlesection of the outer surface of the compacting wheel is sunken to be arc-shaped, cylindrical surfaces at two ends of the surface adopt linear design, and end surface edges are chamfered; a large holeis formed in the outer side of the compaction wheel middle part and used for fixing a bearing, and an inner small hole is used for containing a fixing shaft. By the adoption of the technical scheme, the compaction wheel is easy to design and manufacture, and the budding rate of corn after sowing can be guaranteed. 本实用新型专利涉及一种玉米播种机的压实轮，属于机械设计与制造领域。所述压实轮整体呈近圆柱体状，其外表面中间段凹陷呈圆弧状，表面两端圆柱面采用直线型设计，端面边倒角；压实轮中间部分，其外侧有大孔用于固定轴承，内部小孔用于放置固定轴。采用上述技术方案，压实轮易于设计与制造，能保证玉米播种后的出芽率。
