摘要
A planting unit for a seed machine is described. The planting unit includes a seed meter with a metering member that moves seed along a first path to a release position, at which the seed is moving in a first direction. A delivery system receives seed from the metering member at the release position and moves the seed in a second direction by way of a brush belt with flexible bristles that sweep seed off the metering member. A blocking member has a blocking face adjacent the first path to prevent movement of the seed in the second direction until the seed has passed the blocking face, and to deflect a first portion of the flexible bristles. The blocking member includes a transition surface to allow the deflected bristles to return gradually to an un-deflected configuration as the bristles travel downstream of the blocking face.
