Abstract:
Applications of intelligent agricultural machinery for the Mekong river delta have been recognized as a key to its stable and sustainable development. And, the facts have pointed out that designing and manufacturing agricultural machinery suitable for local conditions are the most important in the issue of agricultural mechanization. This paper presents the design, fabrication, and testing of the peanut sowing component using a vacuum drum for a remote-controlled peanut sowing machine. The experimental results indicate that the rate of picking-up and releasing peanuts of the vacuum drum seeder depends on both the vacuum pressure and picking-up hole diameter. Specifically, as the hole diameter on the cylinder is less than 4 mm or greater or equal to 5 mm, the percentage rates of peanut seeding under vacuum pressure range from -0.1 to -0.4 kg/cm2 and a speed of 10 RPM are lower than 85% or higher than 120%, respectively. According to the testing results, the optimized hole diameter and vacuum pressure are 4 mm and -0.2 kg/cm2 with the seeding percentage rate of around 95%, respectively. The seeding uniformity between two planting rows achieves over 98%.
