Ploughing is one of the most important tillage processes because permits to properly arrange the soil in order to accommodate the crop. During this process, wear is generated by the interaction between tillage tool and soil. Wear phenomenon may cause an increase of fuel consumption of the tractor, a lower quality of the process, and a high maintenance costs due to the frequent parts replacement. A methodology has been developed for the evaluation of the pressure distribution generated by the soil on plough components. Field tests were carried out with a four furrow plough. Pressure on the different parts of the working body was measured with tactile sensors and tests were carried out on a sandy-clay loam soil at three different speeds. The analysis of the results shows that pressure signals are spiky because the soil is not constantly in contact with the plough. Moreover, the speed affects the spike patterns: higher is the speed and higher is the number of spikes and the trend of spike distribution. The evaluation of the pressure produced by the soil on ploughs is useful for improving the comprehension of the soil cutting process.

Abstract

Ploughing is one of the most important tillage processes because permits to properly arrange the soil in order to accommodate the crop. During this process, wear is generated by the interaction between tillage tool and soil. Wear phenomenon may cause an increase of fuel consumption of the tractor, a lower quality of the process, and a high maintenance costs due to the frequent parts replacement. A methodology has been developed for the evaluation of the pressure distribution generated by the soil on plough components. Field tests were carried out with a four furrow plough. Pressure on the different parts of the working body was measured with tactile sensors and tests were carried out on a sandy-clay loam soil at three different speeds. The analysis of the results shows that pressure signals are spiky because the soil is not constantly in contact with the plough. Moreover, the speed affects the spike patterns: higher is the speed and higher is the number of spikes and the trend of spike distribution. The evaluation of the pressure produced by the soil on ploughs is useful for improving the comprehension of the soil cutting process.
