Results of theoretical and experimental researches about determination the corn seed separator sieve parameters of the corn-thresher machine

Abstract

For use in Uzbek fields, a novel sort of corn-thresher machine was created and tested. To separate the cornhusks from the pods, the peeler bars were positioned symmetrically on the cornthresher machine’s rotor surface. However, around 4-5 percent grain was going out from machine’s outlet for pith and husk when the corn thresher was tested experimentally. It was decided to create the sieve in order to save losing grain from outlet. We observed the sieve theoretically to determine the optimal parameters for the corn thresher. The corn thresher machine was equipped with specific grain separator sieve in front of outlet. Some experimental researches were carried out to define optimal parameters of the sieve for developed corn-thresher machine. Minimal amount of grain and impurities in the grain that coming from outlet is ensured during the technological process of the machine. The corn-thresher machine uses the least amount of metal and energy while functioning qualitatively. The corn-thresher machine weighs 400 kg, uses 5 KW of power, and can process 4600 kg of grain per hour in pure time.
