Abstract

Harvesting of wheat crop is one of the important agricultural operations which demands considerable amount of labour in the case of the use manual harvest. Wheat prevalent harvesting methods in Egypt are manual cutting traditional and by reaper. The present study was carried out to manufacture and evaluate a self propelled vertical conveyor reaper with cutting width of 1.5 m. The reaper was operated by using 12 hp diesel engine and four wheels ground to harvest wheat crop .The reaper consists of two main parts: reaping–conveying part (reaping head) and driving, mobile part (motive power). In order to maintain the wheat stalks complete without wasting. Used by the farmer in order to feed the animals after threshing by threshing machines to overcome the problems resulting from the use of combine harvest. As well as to overcome the high cost of manual harvesting. This Innovative Mechanical machine ensures 100% recovery of straw with negligible grain losses at a surprisingly low cost of operation and will save time. This machine can be used in wheat, rice, barley and other grain crops.With this machine, we hope to provide farmers nationwide with a way to harvest grains on small plots of land in cities and along the periphery of urban areas. The variables of this study were : four forward harvesting speeds of, 2.1, 3.0, 4.2 and 5.1 km/h, four grain moisture content of, 23.5, 21.3, 19.1 and 16.3 %, w.b. and four levels of cut of, 5, 8, 12 and 15 cm. The above mentioned variable were tests to examine their effects on total grain losses,%, harvesting efficiency %, effective field capacity fed/h, energy consumption, kW.h/fed, operating cost, L.E./fed, and criterion cost, L.E./fed. The experimental results reveal that the maximum total grain losses of 2.6, %was recorded at forward speed of 5.1 km/h, levels cut of 5 cm and grain moisture content of 16.3 %. The minimum effective field capacity of 0.61 fed/h at forward speed of 2.1 km/h, levels cut of 5 cm and grain moisture content of 23.5 %.
The minimum energy consumed of 5.0 kW.h/fed at forward speed of 5.1 km/h, levels cut of 15 cm and grain moisture content of 16.3 %. The maximum operating cost of 30.49 L.E./fed was recorded at forward speed of 2.1 km/h, levels cut of 5 cm and grain moisture content of 23.5 %.
