| Abstract | ||
| The main objective of this research is to maximize utilization of Japanese combine by improving chopping unit to chop rice straw during harvesting process. The performance of the chopping unit was evaluated under four forward speed (0.35, 0.55, 0.75 and 1 m/s), three cutting speed (450, 550, 650 rpm) and three distance overlapping between fixed and rotary knives (6.0, 8.0, 10.0cm). The main results can be summarized as follows: 1- The average of cutting length decreased and the distribution percentage of short pieces increased by increasing each of forward and cutting speeds and overlapping between fixed and rotary knives. 2- The highest percentage value (83%) of short pieces (< 6cm) were obtained at "0.75m/s, 550rpm, 10cm" forward and cutting speeds at overlapping between knives respectively. 3- The highest field capacity (0.68fed/h) and productivity (2040kg/h) were obtained at "0.75m/s and 550rpm" forward and cutting speeds. 4- The power consummation was increased with increasing forward and cutting speeds, while the energy requirement (kW.h/ton) increased with decreasing forward speed and increasing cutting speed. | ||
