摘要
An improved finger type seed meter back plate seeding device for farming has a modified back plate has a wall having a circumferential groove on over half of the inner perimeter. This groove helps in improving the way seeds are presented to fingers and ultimately the exit hole. It reduces the incidence of jamming of seeds or of seeds being missed by the fingers which take seeds to the exit hole. This groove has three main variations to accomodate various sizes and shapes of seeds: A groove with and added side bump which rotates flat seeds so that their flat side is parallel to the bottom of the groove, a groove with a narrowing which funnels the seeds for a better grasping by the fingers, and a groove with a combination side bump and narrowing.
