Abstract

The burning of crop residues is one of national problems in Egypt especially after harvesting or threshing operations to the different crops.  The main objective in the present study is: Design, fabricate and evaluate the mechanical system of threshing and handling rice straw directly to the baler. A conveyor belt was desgined to transport the rice straw from threshing machine to the baler. Selections of all bearings of the mechanical system were done according to the load carrying capacity. Welding joints were checked against the stresses. The fuel consumption was measured for the system. The power requirement to operate the belt conveyor and baler was calculated. All power calculations were provided to indicate the size of tractor and evaluate the performance of the proposed system. Several experiments and tests were carried out at different speeds. The conveyor dimensions were determined to be 3000 mm length, 750 mm width and the height was variable to be adjusted opposite to the machine throw and the feeding of baler. The belt conveyor was covered with a canvas to reduce dust broadcasting.
