Project Description

Traditional manual seed sowing methods often result in uneven seed distribution, inconsistent planting depth, excessive seed wastage, and increased labor requirements. These issues directly affect crop growth, germination rates, and overall agricultural productivity. The Multi-Purpose Agricultural Seeder Machine is designed to overcome these challenges by providing a reliable and economical solution for precision seed planting. The machine consists of a lightweight mild steel fabricated frame mounted on ground wheels that drive the seed metering mechanism through a chain transmission system. Adjustable seed plates allow different seed sizes to be accommodated, enabling the machine to sow crops such as maize, soybean, groundnut, sunflower, wheat, and pulses. The adjustable spacing and depth control mechanisms ensure uniform planting according to crop requirements. An optional fertilizer attachment enables simultaneous fertilizer application during sowing, reducing the need for separate field operations. The manually operated design eliminates fuel consumption and makes the machine suitable for rural areas where mechanized farming equipment may not be economically feasible. This project provides students with practical exposure to agricultural machinery design, fabrication, power transmission, precision farming techniques, ergonomic design, and sustainable farming practices while addressing real-world agricultural challenges faced by small-scale farmers.
