Paddy Seed Planting Machines

Abstract

The research aims to design and develop a paddy seed planting. The objectives are as follows: 1) to design and develop a paddy seed planting machine suitable for direct-seeded rice cultivation, to evaluate the efficiency and to assess the economic viability of using the Paddy Seed Planting Machine. The researchers have effectively designed and constructed a paddy seed planting machine for direct rice seeding, which is powered by a 9 Hp engine. The dimensions of 2,000 mm. in width, 2,700 mm. in length, and 1,450 mm. in height, with a corresponding weight of 400 kilograms. It can sow rice in 8 rows simultaneously, with a seed drop of 5-8 seeds/point. Experimental results indicate that the machine can seed rice at an average rate was 1.46 rai/hour, with an average seed usage rate was 8 kg./rai. an average was 6.81 seeds/point. The average fuel consumption rate was 2.2 liters/rai, and the average yield is 425 kg./rai, with the potential to increase yield by 24.63%. In assessing the economic feasibility, scrutiny revolves around the project's investment outlay, particularly the capital expenditure required for procuring the seedling-seeding machine tailored for direct-seeded rice cultivation, priced at 150,000 baht. It is found that the direct-seeded rice cultivation method using the paddy seed planting machine incurs a cost of 3,660 baht/rai, which can be reduced by 18% compared to the traditional methods. The payback period is 0.62 years, or approximately 7.42 months.
