Structural Design and Simulation Analysis of a Dual-Row Pneumatic Vegetable Precision Planter

In order to solve the problems of domestic and foreign vegetable precision metering devices that easily damage seeds have low seeding efficiency poor qualification rate, this paper designs a one-machine for two-row pneumatic combination seeder, which is mainly composed mechanism honeycomb mechanism. The other components theoretical analysis working process combined seed device clarifies minimum negative pressure adsorbing during suction stage, along with required seed-carrying stage. It also establishes speed movement planting trajectory parameter equation uses ADAMS software conduct virtual experiments on influence number holes, diameters, heights different types disks success rate seeding. Based research previous mechanisms, single factor tests, orthogonal high-speed photography tests disk seeder were carried out diameter height results conducted okra showed when rotating disc was 18 r/min, hole 2.4 mm, vacuum degree 3.5 kPa, holes 24, 13 60 performance meter reached optimal level, provides reference development small seeder.
