Second-grade separator

Abstract

The invention provides a second-grade separator in the technical field of grain separation machinery. The second-grade separator comprises an upper shell and a lower shell; a feed port is formed in the top of the upper shell; the upper shell is connected with a feeding wheel capable of rotating; a feeding groove is formed in the feeding wheel; multiple arranging plate sets are arranged in the upper shell in the height direction; materials in the feeding groove fall onto the arranging plate sets; the arranging plate sets comprise left arranging plates and right arranging plates; the bottoms ofthe left arranging plates extend to one ends of the right arranging plates; the ends of the right arranging plates extend to the left arranging plates of the next arranging plate sets; first air waysare formed between the adjacent right arranging plates; an air sucker is arranged at the top of the upper shell; an air sucking port of the air ducker communicates with the upper shell; the upper shell rightly below the air sucking port is connected with a conveying mechanism; two screen frames capable of swinging are arranged in the lower shell in the height direction; screens and impurity platesare connected to the screen frames from top to bottom, and are downwards inclined; and the lower shell is provided with a separation module capable of rotating. The second-grade separator is high inworking efficiency and excellent in grain cleaning effect.

Description

technical field [0001] The invention relates to the technical field of cleaning machinery, in particular to a cleaning machine for removing impurities in grain. Background technique [0002] When traditional crop seeds are received, they will be manually operated or dropped from high altitude to remove chaff, chaff, soil and other impurities in the grain. The wind will blow the chaff and soil and other impurities in the grain. It is difficult to remove the heavier stones and other impurities that exist in the drying process, and the labor intensity of manual operation is high, the cost is high, and the work efficiency is low. [0003] In the prior art, people use high-altitude throwing to remove lighter impurities such as chaff, chaff, and soil in the grains. The thrown lighter impurities diffuse into the air, causing pollution to the surrounding environment, and the labor intensity is high. Low working efficiency; small stones and other heavy impurities are separated from ...

AI Technical Summary

Problems solved by technology

[0004] In view of the defects in the prior art, the purpose of the present invention is to solve the technical problems of low work efficiency and poor impurity removal effect in the prior art, and provide a two-stage cleaning machine, which has a high degree of automation and can automatically separate impurities and Grain, high work efficiency, dust and other impurities generated during the separation process will not spread outward, will not cause environmental pollution, and is more environmentally friendly
