Abstract:Vacuum precision seed metering is the key part of vacuum seed planter. Planting performance of planter is affected by vacuum and air flow which are important parameters for choosing fan. Effects of qualification percent and miss percent on air chamber vacuum 3, 4, 5 and 6 kPa were studied at different operating speeds. The results showed that operating performance of the seed metering was excellent when air chamber vacuum was 5 and 6 kPa, which air flow was 7.4–8.0 m3 · s?1 and 8.0–8.8 m3 · s?1, respectively.
Keywords:seed planter  precision seed metering  vacuum degree  air flow
