tailieunhanh - Ergonomics evaluation of single row power weeder for rice

Weed control is one of the most difficult tasks on an agricultural farm. Mechanical weed control not only uproots the weeds between the crop rows but also keeps the soil surface loose, ensuring better soil aeration and water intake capacity. The developed weeder should have the following features: hp, 2-stroke petrol engine. It is compact light low weight equipment, self-propelled with durable floating system. It is centrally driven with worm gear box for transmission. The working width of the developed machine could be adjusted between 140mm to 250mm. | 2018 7 1 681-686 EXCELLENT PUBLISHERS International Journal of Current Microbiology andAppliedSciences ISSN 2319-7706 Volume 7 Number 01 2018 Journal homepage http Original Research Article https Ergonomics Evaluation of Single Row Power Weeder for Rice Aditya Sirmour1 Ajay Verma1 Mukesh Pandey2 and Animesh Chandrawanshi1 1 Department of Farm Machinery and Power Engineering Faculty of Agricultural Engineering Raipur India 2Department of Agronomy Faculty of Agricultural Engineering Raipur India Corresponding author ABSTRACT Keywords Ergonomics Power weeder Rice Mechanical weed control Article Info Accepted 06 December 2017 Available Online 10 January 2018 Weed control is one of the most difficult tasks on an agricultural farm. Mechanical weed control not only uproots the weeds between the crop rows but also keeps the soil surface loose ensuring better soil aeration and water intake capacity. The developed weeder should have the following features hp 2-stroke petrol engine. It is compact light low weight equipment self-propelled with durable floating system. It is centrally driven with worm gear box for transmission. The working width of the developed machine could be adjusted between 140mm to 250mm. It is equipped with rotating blades with 176 rpm and is centrally driven. The cardiac cost involved in the operation of power paddy weeder was found out and the mean working heart rate value of the subject was 108 beats min-1. The energy expended during operation of a power paddy weeder was kJ min-1. The oxygen uptake in terms of VO2 max was 46 which was above the acceptable limit of 35 of VO2 max. Mean overall discomfort rating on a 10 point visual analogue discomfort scale 0- no discomfort 10- extreme discomfort was and scaled as light discomfort . Introduction Weeding out of unwanted plants is a very difficult task in Indian agriculture manually as well as .
