Design and fabrication of automatic single-rice seeding system with The Seed-Selected Tray

Abstract

A design and construction of automatic single-rice seedling machine. The main components of this machine consists of: 1) main frame 2) planting tray conveyor set 3) planting material feeding set1 (pre) 4) single-grain rice sprinkling set 5) planting material feeding set2 (post), and 6) automatic control unit. The result shows that the appropriate linear velocity of planting tray conveyor set equal to 16.67 meters per minute (0.28 meters per second). For the planting material feeding set1 (pre) has the angle of repose is 30 degrees and revolution speed of vibrating motor is 1,673 rpm. which has a feeding capacity equal to 67 kilograms per hour. This condition can be control amount of planting material feeding in the middle of the hole by requirement method. The single-grain rice sprinkling set has the incline angle is 16 degrees and the combination of double vibrating motor are 1818 and 1648 rpm. in revolution speed, respectively. The effects of this set can be show single-grain rice sprinkling efficiency equal to 92 percent.
