## Abstract

A seed package handling system is provided for a test plot combine. A seed packaging assembly in the combine packages the seeds and deposits the packages onto a conveyor, which transports the packages to a first hopper. After the first hopper has received a predetermined quantity or weight of seed, the first hopper is raised on an elevator and then tilted so as to dump the seed packages into a larger second hopper. After the second hopper has received a predetermined quantity or weight of seed, the second hopper is tilted to discharge the seed packages into a wagon separate from the combine, which transports the seed packages to a processing facility. The movement of the conveyor and first hopper is controlled by a PLC.

## Claims

### Claim 1

A package conveyor system for seed test plot combines, comprising:
a combine for harvesting seed;
a packaging mechanism on the combine for placing selected seeds into a plurality of self contained packages;
a conveyor for delivering the packages to a first hopper;
an elevator on the combine for lifting the first hopper to an elevated position;
first means on the combine for tipping the first hopper and dumping the package therein to a second hopper which is greater in size than the first hopper;
second means on the combine for tipping the second hopper for unloading the second hopper into a transport vehicle from the combine; and
a computer mounted on the combine and operatively connected to the elevator to lift the first hopper when the first hopper receives a predetermined quantity of packages.

### Claim 2 (depends on 1)

The system of claim 1 wherein the computer is operatively connected to the conveyor delivering the packages to the first hopper to control said conveyor while the first hopper is being lifted.

### Claim 3 (depends on 2)

The system of claim 2, wherein the computer is operatively connected to the first and second means for tipping to control the tipping of the first hopper.

### Claim 4 (depends on 1)

The system of claim 1 further comprising a first motor for actuating the conveyor and a second motor for actuating the elevator.

### Claim 5 (depends on 1)

The system of claim 1 wherein the second hopper has a normally closed spring loaded discharge chute that pivots away from the second hopper to a discharge position via the weight of the packages when the second hopper is tipped to facilitate the unloading of packages from the second hopper without tipping the second hopper to the angle of response of the chute in its discharge position.
