Description

一种立式砂辊碾米装置 技术领域
本实用新型涉及碾米装置技术领域，具体的讲是一种立式砂辊碾米装置。
背景技术
碾米机是一种常用的农用机械，是用来将玉米、高梁、谷子等杂粮进行脱皮的专业机械。碾米机的工作原理简单的说，就是糙米通过碾米机的碾米室后，通过内压力的作用，铁辊或砂辊的旋转，让米粒与米粒之间，米粒与筛板，米粒与米辊进行充分的磨擦、擦削等，达到去除表面的米皮，适当着水，从而获得光滑晶亮的外观。
目前的立式砂辊碾米机的砂辊整体为圆柱形的，研磨的效果不好，会产生研磨不均匀的现象，本专利提出一种用于立式砂辊碾米机中的碾米装置，用于提高碾米机的碾米效果。
发明内容
本实用新型要解决的技术问题是针对以上不足，提供一种立式砂辊碾米装置，该碾米装置可以对米进行粗磨和细磨，提高研磨的均匀度。
