Pneumatic Metering Type Precision Paddy Seeder

Developing a pneumatic seed metering-type precision paddy seeder to address issues are associated with existing row seeding machines such as uneven seed pattern within the row by reduced precision of seed metering, seed delivery tube blockage by mud and tiredness of operator due to lack of prime mover. Seed metering device consists of two-stroke engine-driven blower fan for developing airflow, air delivery tubes connected from air blower to parallelly connected 6 seed delivery tubes, 8kg capacity seed hopper for storing seeds, and six seed releasing tubes connected from seed hopper to middle of the seed delivery tube. The number of paddy seed release to the field by the seed delivery tubes depends on the rpm of the air blower. Seed releasing valves can regulate the variations due to different seed varieties, germination stage of seeds or moisture condition of seeds for continuous seed release. Seed spacing within the row can be adjusted with controlled seed releasing rate by changes of blower speed and prime mover speed or operator’s walking speed.
