  • Patent number: 4407111
    Abstract: The preferred and illustrated embodiment of this disclosure sets forth a harvesting device for stalk crops such as sweet sorghum or sugar cane. The apparatus incorporates a pair of spaced counter-rotating cutter blades which include cutters or splines which pinch the stalks at many places to feed the stalks. They feed the stalks toward an extraction drum. The extraction drum crushes the stalks cooperative with a pair of counter-rotating rollers. This squeezes the recoverable liquid and pulp from the stalk, and that flows downwardly into the bottom of the apparatus where a container collects it and it is subsequently removed. The dry, broken pieces of the stalks are then fed out of the apparatus into a chopper and then into a large centrifial blower which blows the pulp and chopped pieces away from the apparatus.
