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.

1. An unloading apparatus for a seed box having a bottom with an outlet and a gate selectively transversely moving across and closing said outlet, the unloading apparatus comprising a support frame for positioning the seed box thereon, a downspout mounted within said frame and connecting to a delivery conveyor for transporting seed from said box to a seeder implement, and a seal arrangement mounted in said support frame and positioned between the seed bin outlet and the downspout, the seal arrangement having upper and lower portions, the upper portion spring biased to an extended position so as to mate with and seal against the seed box outlet so that when said gate is opened, no or minimal seed is lost. 2. The seed dispensing apparatus set forth in claim 1 wherein said seal arrangement includes upper and lower spout frames, the upper spout frame collapsing downwardly into the lower spout frame when urged downwardly by the weight of a seed bin placed thereon. 3. The seed dispensing apparatus set forth in claim 2 wherein there are springs extending between said upper and lower spout frames to urge said upper spout frame snugly against said seed bin when placed thereon.
