Uniform-screening rice screening machine

Abstract

The invention discloses a rice screening machine capable of achieving uniform screening, and relates to the field of screening machines. The device comprises a screening box, a feeding port and a guide block, a cushion block is fixed to the upper portion of the inner side of the screening box, a first spring is fixed to the top of the cushion block, a filter screen is fixed to the top of the first spring, a movable rod is installed at the bottom in the screening box, a filter element is installed at the top of the movable rod, and telescopic rods are installed on the two sides of the filter element; by arranging a filter screen and a filter element which are different in aperture size, the rice screening device can effectively screen impurities of two specifications, namely coarse impurities and fine impurities, in rice, the rice can be screened more thoroughly, the rice screening efficiency is improved, the rice screening efficiency is improved, and the rice screening efficiency is improved. And through mutual cooperation of a first spring and a shell, the screening efficiency of the screening machine is improved, meanwhile, the production progress of the rice is accelerated, and the practicability is better.

Description

technical field [0001] The invention relates to the field of screening machines, in particular to a rice screening machine with uniform screening. Background technique [0002] Rice needs to be screened by a screening machine during processing, and a rice screening machine is a device used to screen and remove stones and sundries in rice. [0003] According to the findings of the inspection institute, the Chinese patent with the patent number CN201710353211.7 discloses a rice screening machine that can be efficiently screened. The groove and the sliding bar cooperate with each other, which can quickly screen the rice when the screening machine is screening the rice, so that the screening machine is more efficient when screening the rice, but there are still problems in this patent, which only passes the screen. The screening operation of rice with a simple structure may cause the rice to be screened in time, resulting in low purity of the rice. In addition, some of these im...
