Design a seed metering wheel for sowing pigeon pea seeds

Physical properties of grains plays play important role in the design of seed hopper, conveyers and seed metering device. The physical properties of pigeon pea grains at different range of moisture content from 10.3 to 20.3 d.b. were investigated. The pigeon pea grains dimensions such as length, width thickness and diameter increase linearly with increase moisture content.
