Finite Element Analysis of Airflow Field for Vacuum Chamber in Air-Suction Seed Metering Device of No-Till Seeder

Abstract:

In order to study the impact of the different structures in the air-suction seed metering device of no-tillage planter on seeding performance, based on the structural characteristics of vacuum chamber in air-suction seed metering device of no-tillage planter, the air flow finite element analysis of air-suction seed metering device and experimental verification were did. Mainly the law of the distribution of airflow field and seeding performance of the vacuum chamber under the situation of the different distribution diameters of the suction hole were studied in this paper. The result shows that the adsorption performance is best when the suction hole distribution diameter is 150 mm. The conclusion can provide a reference for structural optimization and performance improvement of the air-suction seed metering device of no-tillage planter.
