摘要

Assessing grain distribution characteristics of an axial flow thresher is significant in its design and performance evaluation. These characteristics can be determined by partitioning the stationary thresher along its axis and then measuring the average grain collected in each compartment, which is a cumbersome work. To overcome these practical hindrances a different approach has been proposed and implemented in this paper which involves the precisely selected silicon-implanted piezo-resistive force transducers (Make: Honeywell, Model: FSG15N1A). Each transducer was separately connected to micro-computer through a signal conditioning circuit with appropriately adjusted signal gain which senses the number of wheat grains falling on it with a particular force. Daisy Lab software was used to collect data on micro-computer. The result showed that the grain separation/collection was initially less it rapidly increased and then exponentially decreased along the axial length of thresher. The key results were verified with the already established experimental method. The trend showed that about 80% of total grains got separated and collected in the first 47.67% of the total thresher length.
