Technical Field
The invention relates to the technical field of machinery, in particular to a corn kernel grading and screening device.
Background
At present, corn is an annual male and female same-plant cross-pollination plant, the plant is tall and big, the stem is strong, the corn is an important food crop and feed crop, and is also a crop with the highest total yield all over the world, the planting area and the total yield of the corn are only inferior to rice and wheat, the corn is always known as a long-life food, the corn contains rich protein, fat, vitamins, trace elements, cellulose and the like, and the corn has the function of developing high-nutrition and high-biological function food. After the corn is harvested and threshed, impurities such as skin stalk, sand grains and the like are often doped in the corn, so that the overall quality of the corn is affected. There are generally two types of screening methods available: the screening method has the defects of high labor intensity, high cost, low working efficiency, low screening cleanliness of the corns and the like; the second method is a method using a corn screening machine, the method has the defect of high cost for purchasing the equipment due to the complex structure of the corn screening machine, and in addition, a large amount of dust can be generated in the screening process due to the large amount of impurities in the corn, so that the body health of operators is influenced.
