Abstract

The performance of an experimental crop residues cutting machine has been investigated in this work in order to evaluate the energy requirements for cutting operation of three different crop residues (cotton stalks, corn stalks, and rice straw). The effect of cutting drum speed, knife edge angle and clearance distance on the machine productivity, fuel consumption, required power, specific consumed energy, cutting efficiency and the economical costs at optimum machine operation were, also, studied. The machine evaluated at five cutting drum speeds 1200, 1300, 1400, 1500 and 1600 rpm (8.29,8.98,9.68,10.37 and 11.06m/s); five knife edge angles (20°, 25°, 30°, 35° and 40°); and five clearance distance (1, 2, 3, 4 and 5mm). The results showed that the maximum cutting efficiency for cotton stalks (20.56% M_cwb),corn stalks (25.64% M_cwb), and rice straw (14.8% M_cwb) were 67.7%, 47.59,% and 62.75%, respectively, at 1600 rpm cutting drum speed, 20°knife edge angle, and 1mm clearance distance.
