Design and development of a power tiller operated seed-cum-ferti till-drill machine

摘要

The adoption of power tiller is slowly increasing in India. However, suitable conservation seed cum fertilizer drill is to be evolved. Therefore, in order to minimize the soil moisture loss and turnaround time and energy loss during seed bed preparation and seeding operations, a seeding attachment was designed and developed for riding type of power tiller at Faculty of Agricultural Engineering, IGKV, Raipur, India. The main design considerations were to place seed and fertilizer with tractive type of tines while rotatilling the field with rotary tiller. The roto tiller need not to remove as it developed back thrust and increased pulling capacity of power tiller, which was revealed by work done and fuel consumption of power tiller with and without developed machine attachment. Thus seeding and tilling accomplished in single pass with conserving energy and in situ soil moisture. It saved operational time and cost of operation. The developed machine consisted a seed cum fertilizer box, four fluted feed rollers, four rigid tines mounted on toolbar with reversible shovels, ground wheel and adjusting devices. Fabrication cost of the machine was worked out about Rs. 6000.00 per unit and its total weight was about 32 kg. All the components of machine worked satisfactory.
