Abstract

Grain separating apparatus comprising an eccentric rotor to dislodge grain from other crop material. The rotor is driven in timed relationship with respect to the straw walkers of a combine whereby a constant gap is maintained between the rotor and the straw walkers.

Claims

1. A GRAIN SEPARATING APPARATUS INCLUDING AT LEAST ONE OSCILLATING SIEVE FOR SEPARATING GRAIN FROM OTHER CROP MATERIAL AND FOR CONVEYING THE OTHER CROP MATERIAL, A ROTOR ROTATABLY MOUNTED, FOR ROTATION ABOUT A SUBSTANTIALLY HORIZONTAL AXIS, IN THE GRAIN SEPARATING APPARATUS ADJACENT TO THE OSCILLATING SIEVE, AT LEAST ONE GROUP OF FINGERS ATTACHED TO THE ROTOR FOR CONVEYING CROP MATERIAL TO THE REAR, A PLURALITY OF SETS OF FINGERS IN SAID ONE GROUP OF FINGERS WITH ONE OR MORE FINGERS IN EACH SET OF FINGERS AND WITH THE MAXIMUM RADIAL DISTANCE FROM THE AXIS OF ROTATION OF THE ROTOR TO A PORTION OF A FINGER VARYING FROM ONE OF THE SETS OF FINGERS TO ANOTHER SET OF FINGER S, DRIVE MEANS TO DRIVE THE ROTOR IN TIMED RELATION TO THE OSCILLAT-

2. The grain separating apparatus of claim 1 wherein the oscillating sieve includes a plurality of straw walkers each of which is journalled on at least one common crankshaft and one group of fingers is attached to the rotor adjacent to each straw walker.

3. The grain separating apparatus of claim 1 wherein each set of fingers in a group of fingers includes a plurality of fingers.

4. The grain separating apparatus of claim 3 wherein all the fingers in one set of fingers are of substantially equal lengths.

5. The grain separating apparatus of claim 2 wherein each set of fingers in a group of fingers includes a plurality of fingers.

6. The grain separating apparatus of claim 5 wherein all the fingers in one set of fingers are of substantially equal lengths.

7. The grain separating apparatus of claim 1 wherein the collecting means is an oscillating grain pan which extends under the oscillating sieve and under the rotor.

8. The grain separating apparatus of claim 2 wherein the collecting means is an oscillating grain pan which extends under the straw walkers and under the rotor.

9. The grain separating apparatus of claim 1 wherein the rotor is rotatably mounted in the grain separating apparatus adjacent to the end of the oscillating sieve which discharges crop material.

10. The grain separating apparatus of claim 2 wherein the rotor is rotatably mounted in the grain separating apparatus adjacent to the end of the straw walkers which discharge crop material.

11. The grain separating apparatus of claim 2 wherein each of the straw walkers include a front section and a rear section and the rotor is mounted adjacent to one end of the front section and above an end of the rear section of each straw walker.
