A study of designing and manufacturing the seed container for rice-seed drill

Abstract

This paper presents the results of a study of designing and manufacturing the seed container for a rice-seed drill, in order to provide the local mechanical factories with data for manufacturing the seed container and rice-seed drills. The seed container of the rice-seed drill is optimally-designed to assure the minimum damage to rice sprouts, and to assure that the sprouted rice-seeds are sown in clusters on the muddy filed. The seed container is made from sheet steel, 1090 mm in length; and is divided into 11 compartments. The cross section of the seed container has two parts: the seed-quantifying part and seed-sowing part. The seed- quantifying part has round shape with the radius of 181 mm. The seed-sowing part has special-designed shape to divide the sprouted seeds into aligned clusters. The seed container has simple structure and small weight; is easily manufactured and has low cost.
