TAILIEUCHUNG - Development of knapsack sprayer engine operated paddy weeder

Farming comprises of land preparation, sowing, plant protection, harvesting and post harvesting. The power source of farm machinery in every aspect is an engine, which is the costliest one in relation with the remaining parts of that machinery. If we could use the same source of power for different aspects, investment could be benefitted with multipurpose operations. Most of the farmers own some frequently required equipment like sprayer for fertigation. | 2018 7 4 3640-3652 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 04 2018 Journal homepage http Original Research Article https Development of Knapsack Sprayer Engine Operated Paddy Weeder .

The power source of farm machinery in every aspect is an engine which is the costliest one in relation with the remaining parts of that machinery. If we could use the same source of power for different aspects investment could be benefitted with multipurpose operations. Most of the farmers own some frequently required equipment like sprayer for fertigation. The engine of the common sprayer is 1hp 2-stroke or 4-stroke with an RPM of 3000 to 9000. If we could use this engine for weeding and harvesting of the crop that could be an economical practice. Various types of mechanical weeders have been developed by researchers. In human operated weeders muscular power is required and so it cannot be operated for long time. The traditional weeding is time consuming and demands high man power. To economically use the knapsack sprayer engine a single row power weeder is designed and developed in Department of Applied Engineering VFSTR Vadlamudi. The developed weeder is a kW a 2-stroke petrol engine with compact and light weight having a durable floating system. It is centrally driven with worm gear box for transmission. The working .
