Construction and Design of a Multi-Crop Threshing Device

Abstract

Threshing seeds was the reason why a thresher was invented in the first place. It is the threshing, blower, and cleaning units that make up the basic components of the machine. For the purpose of simplifying the extraction of seeds, the technique comprises the rotational movement of a cylinder that is fitted with beater pegs and is positioned above a fixed grid. Following the threshing process, the grains are transported into the cleaning unit by means of a conveyor grid. This unit is comprised of sieves that are capable of performing reciprocating action. At the same time as the grains are moving through the sieves, a steady flow of air is being pulled through them. This causes the blower to blow out any particles that are lighter than the grains. In order to function, the equipment was intended to use a ½ horsepower electric motor. It was examined to see whether or not it has the capacity to thresh, separate, and clean the seeds. It was determined that a moisture level of 13% (wet basis) for the seeds and a threshing drum speed of 1500 revolutions per minute were the ideal operating conditions for the machine. The usual method of millet threshing is expected to become less tedious as a result of the successful development of this equipment, which is expected to reduce the effort involved.
