Rice grading machine

The utility model discloses a rice grading machine which comprises an installation frame, a plurality of rice grain separation assemblies and a first driver. The plurality of rice grain separation assemblies are mounted on the mounting frame in an up-and-down distribution manner; the first driver drives the multiple rice grain separation assemblies to operate, rice grains enter from one ends of the rice grain separation assemblies and flow out from the other ends of the rice grain separation assemblies after being subjected to the separation effect of the rice grain separation assemblies, and separation of whole rice and broken rice is completed. The device is high in automation degree, strong in adaptability and high in separation efficiency. 本实用新型公开了大米分级机，包括安装架、若干米粒分离组件和第一驱动器；若干米粒分离组件成上下分布式安装于安装架上；所述第一驱动器驱动若干米粒分离组件运作，米粒从米粒分离组件的一端进入，经过米粒分离组件的分离作用后，再从米粒分离组件的另一端流出，完成整米和碎米的分离。本实用新型自动化程度高、适应性强、分离效率高。
