Research on the Testing of Axial Flow Threshing Apparatus for Improving Their Qualitative Working Indices

Abstract

The working process of the threshing apparatus is characterized by the qualitative working indices they achieve during operation. In order to maximize them with effect on reducing the percentage of seed losses, damaged seeds and impurities in the seed mass, respectively increasing the percentage of separated seeds, certain adjustments can be made on the component elements of a threshing apparatus in accordance with the type, quality and the condition of the material subjected to the threshing operation. In this paper, a n axial flow threshing apparatus was tested under different conditions, in order to be able to obtain the data necessary to adjust the working parameters, which would allow it to be operated at the desired quality indices (losses, injuries and minimal impurities together with separation of seeds from ears and straw almost completely).
