Grain falling impact driven refined grain classificator

Abstract

The invention discloses a grain falling impact driven refined grain classificator which comprises a machine body. A slantways arranged clapboard is integrally connected into the machine body; guidingplates are correspondingly arranged on two sides in the upper end of the machine body; and a sieve plate is movably arranged between the two guiding plates. According to the grain falling impact driven refined grain classificator provided by the invention, the clapboard with a hopper structure is arranged in the machine body, and an impeller is arranged in the lower end of the machine body so as to rotate under the action of the grain falling impact; drag rods are arranged on two sides of the impeller by utilizing a secondary support, and rotary shaft handles are connected between the impellerand the drag rods, so that the upper drag rod can swing at a certain angle under the drive of the impeller and the rotary shaft handles; and a guide plate is arranged in the upper end of the machinebody, and the sieve plate connected with the drag rods is movably arranged on the guiding plates by utilizing springs, so that materials moved through the sieve plate and the clapboard drive the impeller to rotate, the impeller is driven through the drag rods so as to enable the sieve plate to move in a reciprocating way, and grains are filtered and purified by utilizing the gravitational potential energy of the grains.

Description

technical field [0001] The invention relates to the technical field of grain processing, in particular to a fine grain sorting machine driven by the impact of grain falling. Background technique [0002] Due to the continuous improvement of living standards, people have higher and higher requirements for diet quality. Under the existing conditions, people began to make a clear distinction between coarse grains and fine grains, making the difference between coarse grains and fine grains more obvious: coarse grains are relative to the fine grains such as polished rice and white flour that we usually eat, mainly including corn in cereals , purple rice, sorghum, oats, buckwheat, wheat bran, and various dry beans, such as soybeans, green beans, red beans, and mung beans; while fine grains in principle refer to processed grains, generally referring to grains such as flour and rice, according to Different living habits have different standards for fine grains. Except for the unpro...
