Abstract
The device for harvesting corn or similar cereals, which can be constructed particularly as an attachment for combine harvesters or field choppers, having two gathering rollers, which are disposed on either side of a gathering gap for separating the fruit from the plant part bearing it, are driven to rotate about axes of rotation pointing in the direction of travel of the device and are provided with several longitudinally extending cross members, ribs or similar projections, forming working edges protruding over the basic bodies of their rollers. The working edges of the gathering rollers, disposed distributed over the perimeter of the basic bodies of the rollers, traverse working surfaces tapering conically towards the front end of the gathering rollers and with one another or with the basic body of the respectively adjacent gathering roller, form the boundary of the passage gap. The axes of rotation of the gathering rollers converge towards the front ends of the gathering rollers.
