Grain drying and screening device

Abstract

The invention discloses a grain drying and screening device. The device comprises a screening bin and an impurity removing bin, the screening bin and the impurity removing bin are cylindrical cavities with the middles communicating with each other, a vertically-installed storage hopper is arranged at the top of the screening bin, an intelligent control box is arranged on the outer wall of the screening bin, a material dispersing disc and a material uniformizing frame are arranged in the screening bin, an arc-shaped material dispersing rod is arranged on the upper surface of the material dispersing disc, the arc-shaped material dispersing rod is in rotary fit with the upper surface of the material dispersing disc, an air blower is arranged at the position, opposite to the communicating part between the screening bin and the impurity removing bin, of the screening bin, an exhaust fan is arranged on the upper portion of the impurity removing bin, an air pipe is arranged at the top of the impurity removing bin, the air pipe is in communication with the exhaust fan, and the air blower and the exhaust fan are electrically connected with the intelligent control box. Grains fall into the screening bin through the storage hopper, the grains are dispersed step by step through the material dispersing disc and the material uniformizing frame, the situation that the drying effect of a grain drying machine is affected due to accumulation in the falling process of the grains is avoided, meanwhile, impurities in the dispersed grains are conveniently blown into the impurity removing bin by the air blower to be treated in a centralized mode, the influence, on grain drying machine equipment, from the impurities is effectively avoided, and pollution to the environment in the screening and drying process is reduced.

Description

Technical field [0001] The present invention belongs to the field of grain drying auxiliary technology, and more particularly to a grain drying screening device. Background technique [0002] A variety of grains harvested in agriculture should be dehumidified drying treatment, while the purpose of dehumidification drying treatment is to reduce the moisture of its internal moisture, reduce the total water content of cereals, reduce water content, can reduce the energy of grain breathing and consume energy. On the other hand, avoid the moisture content of the moisture, which causes cereals to germinate and mold. In the prior art, large-scale cereal drying mainly uses a grain dryer, which has the advantages of short dehydration time, high drying treatment efficiency, and effectively guarantee the quality of cereal storage, reduced grain mildew, germination, and ensuring food security It played a vital role. In recent years, the grain dryer has developed rapidly and is increasingly w...

Problems solved by technology

[0003] In the prior art, when the grain dryer performs grain drying operations, the grain itself will carry shells, low-quality grain and dust, etc., which need to be separated to avoid affecting the
