AI Technical Summary

Technical Problem

In current rice processing, existing impurity screening equipment cannot effectively separate larger impurities and fine dust impurities, and the screening efficiency is low, which affects subsequent processing.

Method used

It adopts a double-layer screening plate structure with different screen hole sizes. Combined with the design of vibration and quantitative feeding, the eccentric protrusion driven by the rotary motor drives the screening plate to vibrate, and the feeding amount is controlled by the reciprocating screw. It also works with a collection box to collect impurities and rice.

Benefits of technology

It achieves complete separation of rice and impurities, improves screening efficiency, reduces rice accumulation, simplifies the collection process for staff, and improves work efficiency.

Abstract

The utility model relates to the technical field of rice processing impurity removal, in particular to impurity screening and removing equipment for rice processing, which comprises an impurity removing main body, a feeding pipe is mounted on the impurity removing main body, two screening structures are mounted in the impurity removing main body, each screening structure comprises a stabilizing block fixedly mounted on the impurity removing main body, and the stabilizing blocks are connected with the feeding pipe. A plurality of first springs are fixedly installed on the stabilizing block, a screening plate is fixedly installed on the first springs jointly, the screening plate is installed in a slope shape, a notch is formed in the impurity removing body, a plurality of second springs are fixedly installed in the notch, and a lifting plate is fixedly installed on the second springs jointly; and the side wall of the lifting plate is fixedly mounted on the screening plate. Rice and impurities can be separated more thoroughly through multi-layer vibration, meanwhile, the rice screened each time can be quantified, and the situation that excessive rice influences screening is prevented.
