AI Technical Summary

Technical Problem

Traditional linear vibrating screens have flat screens, and the vibration amplitude of rice depends on the adjustment of the vibration motor parameters, resulting in poor screening effect of rice and impurities, and difficulty in effectively removing impurities adhering to the rice.

Method used

The system employs a partition structure, including longitudinally arranged irregularly shaped partitions and a screening screen. The screening screen, combined with angular protrusions, increases the movement range of the rice grains. Through the step-by-step screening by the irregularly shaped partitions and straight screen plates, combined with the vibration of the vibrating motor, the impurity removal effect is enhanced.

Benefits of technology

It improves the screening efficiency and quality of rice and impurities, increases the movement range of rice, makes it easier to peel off impurities adhering to the rice, and improves the screening effect.

Abstract

本实用新型公开了一种稻谷筛分装置,包括振动箱,所述振动箱上设置有隔板结构;本实用新型涉及筛分装置技术领域,稻谷从进料管处加入至箱体中,稻谷首先落入位于上层的异形隔架上,较小的颗粒从多个筛分网处落入下方的异形隔架上,再经过位于下方的多个筛分网进行再次筛分,最小的颗粒落入位于最底端的直网板上,在振动作用下,稻谷从进料管下方的部位逐渐移动至箱体的出料一端,交替经历筛分网与角型凸条,在经过角型凸条时,具有从角型凸条顶部下落至筛分网上的过程,相较于仅依靠振动电机使稻谷在筛分网上跳动,增大了稻谷的运动幅度,易使粘结在稻谷上的杂物与稻谷剥离,提高筛分效率与质量。
