| Abstract | ||||
| This study was conducted for the purpose of developing and manufacturing integrated planting machine with a disc metering device attached crank mechanism suitable for many seeds of different shapes and size. A (4.5 hp) diesel engine as a source of power for machine ground wheel rotation and metering system parts motivation, machine was tested under three ground wheel revolutions GR (30, 45 and 55) rpm, three metering disc to ground wheel revolution ratios MG (0.25, 0.3 and 0.5) and three kinds of seeds variety SV (sun-flower seed, cowpea and black seed).Experimental measurements were taken for the purpose of characterizing the experimental seed factors as follows:shape index (SI), weight of 1000 seeds (W), seeds moisture content (MC) determination, Actual seeds volume (V) and real density (γ). To evaluate the influence of previous factors there were procedural experiments on machine performance with main three measurements visible, invisible and total seeds damage (SD), actual seed feeding rate (SF) /10m of planting row distance and seeds lateral scattering frequency (L.S %) around the planting row centerline. The results showed that: experimental seeds tend to be oval in shape factor and have a low moisture content less than 18.5%, the highest (SD) at the higher value of ground wheel revolutions GR3=55 rpm. The best feeding rate for black seed (4 to 5 seed in feed-blot) obtained with MG2=0.3 while sun flower seed and cowpea (1 seed in feed-blot) with planting distance 20 cm at MG1=0.25 at GR1= 30 rpm. | ||||
