Agricultural corn seed screening device

Abstract

The invention is suitable for the field of screening devices, and provides an agricultural corn seed screening device which comprises a shell, a vibration screening mechanism, an air screening mechanism and a drying mechanism, a feeding port is formed in the upper end of the shell, and a discharging port is formed in one side of the lower end of the shell. The vibrating screen mechanism comprises a vibrating screen movably installed on the inner wall of the shell and a vibrating motor fixedly installed on the inner wall of the shell. The output end of the vibration motor is in contact with the vibration screen; the air screening mechanism comprises a support arranged at the position of a through hole in the middle of the vibrating screen, a plurality of elastic films installed on the support, an elastic driving mechanism located below the support and an air nozzle located above the support. The output end of the elastic driving mechanism is connected with the elastic film; therefore, the vibrating screen and the air screen can be combined, the occupied space of the device is small, and the screening effect is good; meanwhile, the drying mechanism is arranged in the device and can intermittently dry the materials, and the situation that the seed quality is affected due to serious one-time water loss of the seeds is avoided.

Description

technical field [0001] The invention relates to the field of screening devices, in particular to an agricultural corn seed screening device. Background technique [0002] Corn, aliases: maize, cob, corn, corn, corn, corn, pearl rice, bract, big milo, etc. 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 Widely planted. [0003] Corn seeds need to be selected before planting in agricultural production, and corn seeds need to be screened to remove impurities (the impurities that need to be removed include dust, a small amount of broken hay residue and other impurities). The screening device in the prior art It can be roughly divided into two types: airflow screening and traditional mechanical vibration screening. [0004] The seed screen...

AI Technical Summary

Problems solved by technology

[0004] The seed screening device in the prior art cannot effectively combine the above two screening devices, resulting in a large space occupied by the screening device as a whole and low screening efficiency

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
