Corn seed screening device for agricultural breeding

Abstract

The invention discloses a corn seed screening device for agricultural breeding. The corn seed screening device comprises a bottom plate. A left vertical plate and a right vertical plate are verticallyare fixedly installed on the bottom plate; a driven belt wheel is arranged and fixedly installed on a driven shaft in a sleeving mode; a driving belt wheel and the driven belt wheel are sleeved witha transmission belt; a screening basket movably penetrates between the left vertical plate and the right vertical plate in a mode of being inclined towards the lower-right portion; the upper end of aconnecting rod is hinged to the lower-left bottom face of the screening basket; and a first collecting groove is fixedly formed in the lower portion of the screening basket. A hot air machine conductshot air drying on corn seeds in a housing through an air supply pipe and an air collection cover; a driving shaft drives a spiral blade to turn over the corn seeds rotationally, so that hot air and the corn seeds can make full contact, and the drying effect is greatly improved; meanwhile, the corn seeds conveyed on a conveying belt are subjected to secondary air-blowing drying of fan blades and can be spread on the conveying belt, and thus the drying effect is better; and vibration of the screening basket to the corn seeds is facilitated through swinging of the screening basket, and thus thescreening rate is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn seed screening device for agricultural breeding. Background technique [0002] Corn is an annual herbaceous plant belonging to the Gramineae family. It is also known as: maize, cob, corn, rice, corn, corn, pearl rice, bract reed, and millet. Fanmai. Corn has been cultivated in my country for more than 470 years. At present, my country's sown area is about 300 million mu, second only to rice and wheat, and ranks third in food crops. It is second only to the United States in the world, and the tropical and temperate regions of the world It is widely planted and is an important grain. It has a sweet taste and can be used in various dishes, such as fried corn. It is also the main raw material for industrial alcohol and shochu. [0003] Before agricultural production and planting, it is necessary to select corn seeds, and screen and select corn seeds according...

AI Technical Summary

Problems solved by technology

[0003] Before agricultural production and planting, it is necessary to select corn seeds, and screen and select corn seeds according to the size of corn kernels. The existing corn seed screening device has poor screening effect on corn, and the screening efficiency is low. Effective drying of corn kernels during the process is not conducive to the storage of corn seeds
