Abstract

In order to solve the problems of poor universality and complex structure of the current air-suction precision seed metering device for small vegetable seeds, an air-suction precision seed metering device based on the physical characteristics of small vegetable seeds was developed. The physical characteristics of several typical small vegetable seeds were measured to provide a theoretical basis for the design of air-suction precision seed metering device. Analyzed the force on the seed during seed metering, and used discrete element method to analyze the overall state of the seed at different times in combination with the basic structure. The experiment was designed with the pass rate, replay rate and miss rate as experimental indicators. The regression model was established to obtain the reasonable range of each parameter. The experimental results showed that when the rotary table speed was 28.65 r/min and the working negative pressure was 4.40 kPa, the seeding pass rate of the seed meter was 91.07%, the replay rate was 4.70%, and the missed rate was 4.23%.
