Through-flow air screen cleaning and screening device for screening corns

Abstract

The invention discloses a through-flow air screen cleaning and screening device for screening corns, and belongs to the technical field of agricultural machinery. The through-flow air screen cleaningand screening device for screening the corns comprises a feeding component, a power component and a lightweight excluding and screening component; the feeding component is positioned on the outermostside of the device; the power component is arranged on one side in the feeding component; and the lightweight excluding and screening component is arranged on one side of the power component. The through-flow air screen cleaning and screening device for screening the corns is scientific and reasonable, and safe and convenient to use; lightweight impurities, such as corn whisker and corn leaves, doped in the corns are separated from the corns by utilizing crisscross air staggered up and down; and then hollow bad corns mixed in high-quality corns are screened out by purging by utilizing transverse high-speed air; high-density substances, such as stone, doped in the corns are effectively intercepted by utilizing a vibrating effect; and finally, the inclination direction of a corn material guide plate is controlled by utilizing an electromagnet. The effect of switching matched operations of screening and waste material unloading is achieved, so that a waste material cannot remain in the device.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a cross-flow air sieve cleaning device for screening corn. Background technique [0002] With the steady development of agricultural machinery, crop screening equipment was born, and corn screening equipment is a typical representative. Corn screening equipment can retain corn kernels and screen out waste materials such as corn silk and corn pages to improve the overall quality of corn kernels. effect, but the corn screening device in the prior art can only screen light waste materials such as corn leaves, and the phenomenon of entraining corn kernels is easy to occur during the screening process, which is easy to cause waste, and some corn screening equipment for screening stones Only the stones with particles smaller than corn can be screened out, and the large stones will still remain, and the screening is not thorough enough. At the same time, the existing tech...

[0002] With the steady development of agricultural machinery, crop screening equipment was born, and corn screening equipment is a typical representative. Corn screening equipment can retain corn kernels and screen out waste materials such as corn silk and corn pages to improve the overall quality of corn kernels. effect, but the corn screening device in the prior art can only screen light waste materials such as corn leaves, and the phenomenon of entraining corn kernels is easy to occur during the screening process, which is easy to cause waste, and some corn screening equipment for screening stones Only the stones with particles smaller than corn can be screened out, and the large stones will still remain, and the screening is not thorough enough. At the same time, the existing technology does not have the effect of screening out corn damaged by moths, so people need a cross-flow air screen for screening corn. device to solve the above problems
