Design and Development of Seed Metering Device Implemented in Power Tiller

Abstract

This proposed work is focused on designing and implementation of seed sowing process in power tiller vehicle. This project deals with the design of a mechanical machine, which is affordable to farmers, which can plough and sow seeds simultaneously in order to save time. The sowing operation includes laying fertilizer and seed in proper rows at the regular interval, following the covering the seeds with soil and confirming the proper compaction over the seed. To ensure the seed planting at the regular interval, the seed metering device is used in this work which is considered as the key component of the seed sowing process. A wheel is used to drive the seed metering device. This system could effectively reduce the influence of inhomogeneous sowing caused by the slipping of ground wheels. This project aims in designing a machine whose function is to sow groundnut, crops, etc. This designed machine will be more attractive and very much beneficial to all farmers because it reduces the wastage of seeds, time required for sowing, and less man power is required with reduced time consumption. The observations showed that using machine, it consumes 9 s to sow 0.003 h whereas the manual sowing tool 13.2 s.
