| Abstract | ||||
| The chief purpose of this work is to design and develop a new technology of pneumatic medicinal seeds planting "PMSP". An investigated prototype was identified which activates by the air vacuum system. It is made from two drums one inside others. The clearance between them considers a suction chamber. Regulated this space affects the suction volume to get high/low vacuum pressure. Through the indoor experiments, the best vacuum space is identified by two holes on the circumference inner tube with 8.0 mm diameter. The performance of the prototype was evaluated by studying some variables; forward speeds "1.7, 2.0 and 2.4 kmh-1, vacuum drum speeds "20, 22, 24 and 26 rpm", and vacuum pressures "9.0 and 11.0kPa" per constant vacuum holes on the outer drum of 0.75mm diameters. The results indicated that; using vacuum pressure of 9.0 kPa, the highest percentage of latitude seeds distribution relative to seeding centerline was recorded 94.12 and 90.49% respectively, for right and lift exit seeds tubes under the forward speed of 1.7 kmh-1 and vacuum drum speed of 24 rpm. While the corresponding percentages at using vacuum pressures of 11.0 kPa were recorded 90.01 and 94.31% respectively under the above conditions but per the forward speed of 2.0 kmh-1 and vacuum drum speeds of 24 rpm. Also, to realize the lowest miss index "0.0%", multiple indexes "5.0%" and highest quality of feed index "95%" was found at a forward speed of 2.4 kmh-1 and vacuum pressure of 9.0 kPa under vacuum drum speed of 22rpm. | ||||
