Batch corn thresher

Nowadays for the threshing of individual corn cobs at the selection stage there are no commercially available threshing devices of Russian production. Therefore, Russian scientists began to actively develop selective corn threshers, in particular, in the Krasnodar Research Institute of Agriculture named after P. Lukyanenko a batch corn thresher was developed. On the basis of research carried out in the Kuban State Agrarian University, a scheme of a single-corn maize thresher providing a higher quality of maize threshing in comparison with existing structures is proposed. Therefore, the goal of our study is to improve the quality of threshing cobs of corn selection material. The relationship of the geometric parameters of the proposed device and their influence on the technological process of cobs threshing were analyzed. As a result, the conclusion was made that each cob, depending on its diameter, is threshed by one of the elementary threshing devices, i.e., the correspondence of the gaps of the threshing gap with the diameter of the cobs is achieved automatically. There is no need to adjust the gaps of the threshing gap. Thus, the parameters of the process of threshing the сobs of the corn selection material are optimized and the quality of the threshing is improved.
