Design and Experimental Study of a Combined Pneumatic Plot Seed-metering Device for Cotton

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...

Simulation on Magnetic Field Characteristics of Permanent-Magnet Seed-Metering Device

The cylindrical permanent magnet is the core part of the permanent-magnet seed-metering device, it can absorb single magnetic powder coated seed. The first, the magnetic induction intensity model of any point in the cylindrical permanent magnet external was established based on the equivalent current model of permanent magnet. The second, the mathematical formula was derived using the Biot-Sava...

Simulation 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...
