Power Requirement Estimation for Cutting Paddy Crop Using a Standard Cutter Bar

Power Requirement Estimation for Cutting Paddy Crop Using a Standard Cutter Bar A laboratory setup simulating the cutting process of a vertical conveyer reaper in the field was developed to study the effect of crop and machine parameters like the number of hills, knife speed, forward velocity of machine on cutting torque, and power requirement for cutting paddy crop. Experiments were conducted by cutting paddy crops at three different levels each of knife speed, forward velocity, and stem area (number of hills). The statistical analysis of data obtained showed that cutting torque was mostly influenced by stem area than knife speed and forward velocity. A minimum knife velocity of 1.8 m/s was required for cutting paddy stems during harvesting. The forward velocity of the machine should be less than 1.1 km/h to prevent excess loading on the knife. A linear model incorporating knife speed and forward velocity with a coefficient of determination of 0.89 was developed to predict the actual torque required to cut paddy crops with different stem areas. A model for predicting total power required to carry out cutting was also developed which included the power required to overcome frictional (idle) torque and cutting torque. Model estimating the total power required for cutting paddy was validated by comparing the measured and estimated values with an average absolute variation of 14.32%. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

A laboratory setup simulating the cutting process of a vertical conveyer reaper in the field was developed to study the effect of crop and machine parameters like the number of hills, knife speed, forward velocity of machine on cutting torque, and power requirement for cutting paddy crop. Experiments were conducted by cutting paddy crops at three different levels each of knife speed, forward velocity, and stem area (number of hills). The statistical analysis of data obtained showed that cutting torque was mostly influenced by stem area than knife speed and forward velocity. A minimum knife velocity of 1.8 m/s was required for cutting paddy stems during harvesting. The forward velocity of the machine should be less than 1.1 km/h to prevent excess loading on the knife. A linear model incorporating knife speed and forward velocity with a coefficient of determination of 0.89 was developed to predict the actual torque required to cut paddy crops with different stem areas. A model for predicting total power required to carry out cutting was also developed which included the power required to overcome frictional (idle) torque and cutting torque. Model estimating the total power required for cutting paddy was validated by comparing the measured and estimated values with an average absolute variation of 14.32%.
