Abstract

In this study, an effort has been made to design and develop an onion digger for the onion field in India. The onion digger has four wheels and a two-wheel drive machine. The digging system consists of a blade made up of high carbon steel material (EN45), which was the central digging part of the machine having dimensions 1000mm*250mm*10 mm. Fingers of the reaper binder are also provided to protect the blade from obstacles like heavy rocks and tough metals. The spacing of fingers is 180 mm, and the width of each finger is 100mm. Fingers are fastened on the blade with the help of nuts and bolts, and they are easily replaceable when got damaged. The forward operating speed of the machine is 3-5 km/h, and the maximum speed is10 km/h, having a field capacity of 0.2 hectares per hour. The working depth of the machine is 100mm. Depth is suitable for the field with practically no damage to the onion bulb. The fuel consumption of the machine is 3.5 litres per hour when working at full capacity.
