Investigation on the application of subsoiler vibration to reduce the energy requirement

Abstract

Abstract The aims of this study were to investigate the input energy in vibrating and non-vibrating subsoiler wings based on field operations and to compare the field performance based on the energy use efficiency to determine the best between them. The study was carried out using vibrating and non-vibrating wings of the subsoiler and two rake angles in the soil (45° and 55°). Three tractor speeds (2.88, 4, and 5.6 km/h) were considered. The results showed that input energy in non-vibrating wings was higher than that in vibrating wings at all treatments. Analysis of the energy input showed the diesel fuel had the largest inputs form all input energy for both wings types. The treatment of 45° with 2.88 km/h had the largest share of input energy with 1528.95 MJ/ha in non-vibrating wings while the treatment of 55° with 2.88 km/h had the largest share 1239.86 MJ/ha in vibrating wings. Total volume of soil disturbance in vibrating wings and non-vibrating wings was 2704.185 and 3586.491 m3/ha, respectively. Accordingly, energy use efficiency for vibrating wings higher than non-vibrating wings. Finally, vibrating wings surpassed non-vibrating wings in field performance and it can produce higher cross-section soil with the least input energy consumed.
