A two-stage grain primary cleaning equipment

Abstract

The invention discloses two-stage grain preliminary cleaning equipment, and relates to the technical field of grain cleaning equipment. The two-stage grain preliminary cleaning equipment comprises a protective cover, a grain inlet chamber, a sifting chamber and a grain outlet chamber; the grain inlet chamber, the sifting chamber and the grain outlet chamber are connected in sequence; the protective cover is of a half-cylinder-shaped box structure; the protective cover is hinged with one end side of the grain inlet chamber; the other end of the grain inlet chamber is provided with a first-stagegrain sifting plate; one end side of the sifting chamber is provided with a grain guide hopper corresponding to the first-stage grain sifting plate; a roller corresponding to the grain guide hopper in position is arranged in the sifting chamber; one side of the roller is provided with a baffle; and a second-stage grain sifting plate corresponding to the baffle in position is arranged in the grainoutlet chamber. According to the two-stage grain preliminary cleaning equipment disclosed by the invention, by installing the first-stage grain sifting plate, the roller and the second-stage grain sifting plate, wherein the number of the first-stage grain sifting plates is 0.2 to 0.8 times than that of the second-stage grain sifting plates, and by combining with the protective cover and installing the two stages of sifters, the grain impurity sifting effect is improved, impurities can be convenient to clear, and equipment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of grain cleaning equipment, in particular to a two-stage grain primary cleaning equipment. Background technique [0002] Grain cleaning machinery is a grain processing machinery used for cleaning, selecting and grading. Different types of grain cleaning machinery use different working principles to separate grain particles from impurities. [0003] General grain screening equipment also needs to be equipped with cylinder initial cleaning screen, fan or vibrating screen, etc. However, adding these auxiliary equipment is cumbersome in structure, takes up space, and increases cost, which brings many troubles to users. Some customers do not want to be equipped with initial screen Cleaning equipment, but when there are many impurities in the grain, it will seriously affect the quality of the grain, and it is not conducive to the subsequent processing of the grain. Therefore, a grain primary cleaning equipment th...
