tailieunhanh - Development of electronically meterized maize planter

A seed metering mechanism of conventional precision planters are usually driven by ground wheel with chain and sprocket system and these mechanisms are of mechanical type. They are less efficient as there is a number of losses while transmitting the power. Due to continuous friction between moving parts, these devices are subjected to wear and tear; hence they require frequent maintenance. To improve the planting performance of precision planters, the best substitute is to develop an electronic meterized planter for maize. The design and development of electronic meterized planter includes main frame, hopper, metering unit, furrow opener etc. The speed synchronization between ground wheel and metering unit is vital at it has been taken care by electronically. | 2019 8 4 2432-2440 EXCELLENT PUBLISHERS International Journal of Current Microbiology andAppliedSciences ISSN 2319-7706 Volume 8 Number 04 2019 Journal homepage http Original Research Article https Development of Electronically Meterized Maize Planter C.

Introduction Modernization of agriculture necessitates appropriate machinery for enhancing resource use efficiency and productivity in agriculture. The more precise the planting operation the better the quality and quantity of crop harvested Ebrahim 2008 . The objective of planter in agriculture is to place the seeds at a desired depth rate and spacing within the row. Precision planting reduces seed scattering and excessive use of seeds due to uniform distribution of seeds and by preventing seed from bouncing in the furrow Domier 1991 . Currently there are various
