Abstract
Abstract A stalk pickup for a harvester for harvesting ear laden stalks of corn and the like which have fallen. The present stalk pickup is driven from a transverse horizontal shaft and provides for supporting, in cantilever relation, a plurality of conveyor chains having outstanding lugs thereon, with a chain immediately above the respective snouts of the harvester so that the ear bearing stalks will be picked up and engaged between the lower reach of the cantilever supported chain and the upper face of the snout so that the stalk will move upward at a slightly greater speed than the speed at which the harvester moves over the terrain, with the lower reach of each of the chains moving in the opposite direction to the movement of the harvester over the terrain. Spaced apart polygonal discs, having sharp pointed cutting blades on certain corners, are mounted on the horizontal shaft and rotatable therewith, which serve to cut stalks to prevent entanglement of the stalks with the machinery. Spiral conveyors are provided on each outer snout to direct the stalks upward and inward into the harvester.
