Analysis of operating speed and power consumption of a gear-driven rotary planting mechanism for a 12-kW six-row self-propelled onion transplanter

Aim of study: To determine the optimal working speed a gear-driven rotary planting mechanism for self-propelled riding-type onion transplanter in order to choose an adequate forward effective (Allium cepa L.) seedling planting.
 Area Daejeon, Korea.
 Material and methods: The was composed six hoppers that received free-falling seedlings through supply deposited them into soil. accurate transplantation seedlings, mathematical trajectory modelling mechanism, virtual simulations, validation field experiments were carried out.
 Main results: According model simulation, 0.15 m s-1 rotating 60 rpm favourable uprightness minimum mulch film damage. For proposed transplanting distance calculated as 0.08 m, accuracy deposition hopper demonstrated 97.16% test. From tests, combined with frequency min-1 found be optimum obtaining high (90o), low misplant rate (7.66%), damage area on film, power consumption (36.53 W).
 Research highlights: findings this research might helpful improving design accelerating automation process transplantation.
