NURSE RECEIVER HEADER FOR AIR SEEDERS

摘要

A nurse receiver header for an agricultural planting implement is cooperable with a nurse mechanism that conveys a stream of seeds entrained i n an air stream from a central hopper. A receiver is positioned at the plantin g mechanism to receive the seeds entrained in the air stream and accumulate a supply of the seeds for utilization by the associated planting mechanism. Th e receiver header may include a vent for dissipating the air stream when receiving the seeds for distribution to the receiver. The vent is provided with a hood to keep contaminants from entering the vent and passing into the planti ng mechanism. The receiver header is positioned so that an appropriate supply o f seeds for the planting mechanism fills the tube between the receiver header and the receiver including the vent, resulting in a decreased volume of discharg ed air for the air stream and a diminished ability for the nurse mechanism to convey seeds. The receiver header can be configured to service multiple receivers. The receiver header is mounted at an angle inclined to the vertic al when in an operating position such that the receiver header can be rotated through an angle in the range of 70 - 110 degrees to a transport position without inverting the receiver header, thereby retaining the seeds accumulated in th e receiver.
