| Abstract | ||||
| In the present study a double chopper machine was designed and fabricated locally. It was field tested for evaluating with cotton stalks and corn stalks to measure the machine performance, efficiency and productivity. The machine was modified and fabricated from local materials at a private sector company throw project, which was established through the Regional Council For Agricultural Research and Extension in collaboration with Agricultural Engineering Research Institute. The present research work was conducted at Sakha research station, Kafr El Sheikh Governorate. The main objectives of this study were clearing farm fields from crop residues as soon as possible after harvesting to give a chance for planting the next crop at reduced environmental pollution. Also to produce suitable size or length of chopped materials with homogenous cut materials at increased the rate from farming operations. The optimum results were as follow:- Forward speed 4.7 km/h, rotational speed 1600 rpm (using flail type drum), rotational speed 1200 rpm (at fly wheel) and first cutting efficiency 96.75%, 97.27 % for corn stalks and cotton stalk, respectively. The feed speed to the fly wheel was 4.69 m/sec, smallest cut material 6.5 cm and 4.5cm with corn and cotton stalks and the final cutting efficiencies were 66.25% and 68% for corn stalks and cotton stalks, respectively. | ||||
