Material impurity removal device

The invention relates to the technical field of mechanical equipment, and provides a material impurity removal device which comprises an airflow generator, a support, a chord line and a vibration generator. The airflow generator is used for generating airflow to drive materials to move. The string is tensioned on the support and intersects with the airflow direction. And the vibration generator is used for driving the string to vibrate so as to shake out/pop out impurities in the material in contact with the string. According to the material impurity removing device, impurities in the materials are shaken out/popped out through chord line vibration, the materials can be separated from the impurities, and the quality of the materials is improved. 本申请涉及机械设备技术领域，提供了一种物料除杂装置，物料除杂装置包括气流发生器、支架、弦线以及振动发生器。气流发生器用于产生气流，以带动物料移动。弦线拉张于支架上，弦线与气流方向相交。振动发生器用于驱动弦线振动，以将接触到弦线的物料中的杂质抖出/弹出。本申请提供的物料除杂装置，通过弦线振动，将物料中的杂质抖出/弹出，能够将物料与杂质分离，提高物料的品质。
