现有技术中，多组研磨盘的研磨机大都采用了皮带传动带动多个研磨盘，采用皮带传动，在研磨阻力较大的地面时，皮带容易打滑，造成地面研磨不均匀，这就导致了研磨效率较低，甚至需要二次研磨，并且三个研磨盘的周向公转为垂直电机直接带动研磨盘边缘转动，由于垂直电机安装在边缘，可造成研磨盘重力不均衡，研磨偏斜的问题。

蜗杆传动箱1固定在两个水平放置的机架7之间，副电机5固定在两个机架7之间，蜗杆传动箱1设置在机架7前端，副电机5设置在机架7后端，机架7与万向轴6平行设置。
机架7上表面设有滑轨8，滑轨8上设有沿其移动的配重滑块9。用于调节整机的前后重心。
从动齿轴38为三个，每个从动齿轴38之间的夹角为120°。均匀分布在齿轮箱内，对地面均匀磨削。
工作原理：
每个研磨体37的自转：主电机4通过主转轴11带动蜗杆传动箱1内的主动齿轮31转动，主动齿轮31带动中间齿轮32转动，中间齿轮32带动从动齿轮33转动，最终从动齿轴38上安装的研磨体37转动；
三个研磨体37的公转：主转轴4周围设置的空心轴12与主转轴11的转动互不干涉，副电机5带动万向轴6转动，与万向轴6连接的万向轴齿轮14向蜗杆中间齿17传递动力，蜗杆中间齿17向蜗杆齿轮110传递动力，带动蜗杆齿轮110同轴的蜗杆19转动，蜗杆19向蜗轮13传递动力，蜗轮3固定安装在空心轴12外围，带动空心轴12转动，空心轴12与齿轮箱3固定连接，最终带动齿轮箱3转动，使三个研磨体37绕主转轴11的中心转动。
未提到的结构及连接关系均为公知常识。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
