Abstract
A seed dispensing apparatus comprises a support frame adapted to receive a separate seed bin and with a down spout positioned within the support frame and connected to a delivery conveyor for transporting seed from the bin to a seeder implement. A seal arrangement in the support frame substantially eliminates leakage of expensive seed from the seed bin. The seal arrangement consists of upper and lower telescoping seal parts which are spring biased to an extended position so that when the seed bin is placed on the support frame, the outlet of the seed bin bears against the seal arrangement which is kept in tight engagement with the outlet to prevent seed leakage.
