A device for classifying and screening corn kernels

Abstract

The invention discloses a niblet classifying and screening device. The niblet classifying and screening device comprises a shell; multiple brackets are arranged at the lower end of the shell; feed hoppers are arranged on two sides of the upper end of the shell; feed ports are formed in the lower ends of the feed hoppers and positioned in the shell; first guide plates are arranged on one sides in the feed ports; second guide plates are arranged on the other sides in the feed ports; impurity collecting chambers are arranged on the sides, far from the first guide plates, of the second guide plates; multiple through holes are uniformly formed in one sides of the impurity collecting chambers; multiple air sucking machines are arranged on the other sides of the impurity collecting chambers; guide plates are arranged under the impurity collecting chambers and positioned on the side walls in the shell; and a first fixed plate is arranged at the upper end in the shell and positioned between theimpurity collecting chambers. The niblet classifying and screening device has the following beneficial effects: the screening process is performed in a totally closed box without generating dust; niblet can be totally separated from grain stalks; and meanwhile, the niblet with different fullness degrees can be classified and screened, so that the labor intensity is low, and the working efficiencyis high.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a device for grading and screening corn kernels. Background technique [0002] At present, corn is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop, and it is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. It has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has the development of high nutrition and high biological function food. After the corn is harvested and threshed, impurities such as husks and sand are often mixed into the corn, which affects the overall quality of the corn. There are usually two existing screening methods: one is manual screening, which has the disadvantages of high labor intensity, high cost, low work efficiency, and low sieving purity of...

AI Technical Summary

Problems solved by technology

There are usually two existing screening methods: one is manual screening, which has the disadvantages of high labor intensity, high cost, low work efficiency, and low sieving purity of corn; the other is using corn to screen Machine method, this method has the disadvantage of high cost of purchasing the equipment due to the complex structure of the corn screening machine. In addition, because there are many impurities in the corn, a large amount of dust will appear during the screening process, which will affect the health of the operators.
