On the performance of the inclined plate cell type planter for the sugar beet seed

Abstract

The handy bean planter developed in Hokkaido have the inclined plate cell type seed metering device.
According to the laboratory test with sugar beet seeds, the proper peripheral speed of cell is 0.20-0.27m/sec for ball, 0.20m/sec for segmented seed. The proper cell diameter is 30% larger than the average diameter of seeds. When the inclination of seedplate was more than 50 degree, the seeder can not make precise planting.
The thickness of the seedplate should be same as the diameter of seeds. When the plate thickness is larger than the seed diameter, the seeds are blocked in the cell, especially in the case of segmented seed.
