DESIGN AND PERFORMANCE TEST OF DIRECT SEED METERING DEVICE FOR RICE HILL
نویسندگان
چکیده
In order to meet the requirements of rice field precision direct seeding in rows and hills, a spiral grooved seed metering device for hills is designed. The Matlab software used study movement trajectory buds groove during process. Based on quadratic regression-orthogonal rotation combination design, taking working speed wheel, length helix angle as test factors, well qualified rate hill diameters, grains miss-seeding indicators, performance tested by JPS-12 bench. data are analyzed using Design-Expert 6.0.10 obtain mathematical model between factors indicators. results show that when rise 71.0°, 10.8mm, wheel 23.2r/min, diameter, 91.06%, 94.64% 3.64% respectively. meets agronomic seeding.

This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...
متن کاملSimulation Design of the Spiral Groove Precision Seed-Metering Device for Small Grains
At present, most of small grain crops such as millet and forage seeds are sown by external force feed in mainland China, which has some problems of wasting seeds, uneven seed distribution and so on. Therefore, it is needed to design a precise feed device for small grain corps. The author’s of this paper established a three-dimensional model to design the spiral groove precision seed-metering de...
