Abstract:
A seed metering device for agricultural seeders has a meter housing, a seed disk covering an open side of the meter housing, and a brush assembly mounted within the meter housing and contacting the seed disk. The meter housing has a seed delivery opening for delivering a supply of seed into a seed pool area, an air inlet provided above the seed pool area for receiving a supply of positive pressure air into the meter housing, and a seed exit area where seed can be dropped into a seed tube. The seed disk has seed pockets spaced around its outer circumference that pass through the seed pool and pick up individual seeds as the seed disk rotates. The device includes several features that help singulate and drop seeds in a way that provides a desired number of seeds per acre and a uniform spacing between the seeds in the furrow.
