Design Modification for Anti-choking Mechanism in Thresher Machine

摘要

This paper suggests a modified thresher machine design for minimizing the problem of choking in the concave. As surveyed in the district of Dantaramgarh, Rajasthan, the major hitch faced by the farmers in employing multi-crop thresher machine is the choking of straw and chaff in concave clearance as the speed of feed is increased. As the feed is increased, the chaff aggregate increases considerably and is forced down the clearance and chokes it subsequently. To resolve the issue, a design was suggested that entailed a concave frame to hold the concave instead of being an integral part of mainframe of machine. The mechanism introduced to move the concave frame was termed as anti-choking mechanism.
