Agricultural funnel type screening device for dried corn kernels

Abstract

The invention discloses an agricultural funnel type screening device for dried corn kernels. The device comprises a device body; a base is arranged at the bottom of the device body; a screening chamber is arranged above the base; a driving motor is arranged at the top of the screening chamber; a driving shaft is arranged at the output end of the driving motor; the device body is provided with a collecting bin; a fan is arranged on the base; a dust collecting bin is arranged on the left side of the device body; the device body is provided with a screening mechanism; and the screening mechanismcomprises an upper screening structure and a lower screening structure. The device is simple in structure, materials are screened by the aid of the funnel type structure, the screening effect is good,the screening speed is high, the positions of the materials are changed greatly by the aid of the double screening mechanism, and the very good screening effect is realized; besides, blockage of a feeding opening is effectively avoided under the effect of discharging paddles during screening feeding; in addition, in the whole process, dust in the materials is processed, so that the quality afterscreening is improved; and the device is good in use effect and high in practicability.

Description

technical field [0001] The invention relates to a screening device, in particular to a funnel-type screening device for agricultural dry corn kernels. Background technique [0002] Corn is an annual herbaceous plant of the grass family Zea genus. Alias: corn, stick, corn, corn, millet, corn, corn, pearl rice, bract reed, big miliary millet, it is called pearl grain in Northeast Liaoning dialect, barley kernel in Chaozhou dialect, corn in Cantonese, and fan in Hokkien dialect. wheat. [0003] Corn is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. 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. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition, high-biological function foods. However, due to its comp...

Problems solved by technology

However, due to its complex heredity and rich variation types, there are shortcomings in the conventional breeding process, such as too long cycle, too large coefficient of variation, and affecting the growth and development of offspring. Modern biological breeding technology not only overcomes the above shortcomings and deficiencies, It also improves breeding speed and quality

[0004] After the corn kernels are dried, they generally need to be sieved, and the corn kernels are processed and processed by sieving. At present, many corn sieving methods in agriculture are sieved by manual windmills. This kind of sieving The workload of the method is large, and the existing mechanical screening equipment is basically vibrating screening, but the working efficiency of this screening method is low, because the material moves slowly on the screen and the position changes little , so the effect of sieving is not very good, so it needs to be improved
