Abstract

Objective: To design a semi-automatic thresher, which can produce seeds without having broken grains, un-threshed grains, spilled grains and to reduce the overlapping timespan due to the early arrival of monsoons.Method: The steps involved in the construction of semi-automatic thresher are • Feedback data of the farmers collected from the various surveys and articles. • Designing of the semi-automatic threshing by 3D modelling software. • Material planning and Procurement. • Assembly and installation. • Testing and Validation. Findings: The results obtained from the thresher are plotted in the graphical layout with the equipment type (on X-axis) and the quantity threshed efficiently (on Y-axis). The Semi-automated thresher are selected as an optimum one among the preferred choices, based on the driving parameters such as good efficiency, low accident history, power independent, easy mode of transfer and portable equipment which will facilitate the farmers to reach the delta area easily. Applications/Improvements: • Versatile utility equipment for different grain seeds (maize, cow pea) by small changes in the design. • Collecting tray is pivoted over a revolving cam to discern the chaff.
