Abstract
A machine for harvesting the overground foliage of a row crop growing in a field. The machine has a plurality of stripping wheels each for harvesting and disintegrating the foliage in one row of the crop. Each stripping wheel is arranged in a casing having an obliquely upwardly directed outlet, and produces an air stream for transporting the disintegrated foliage up through the outlet of the casing. In order to attain great cutting efficiency per time unit and keep the harvested material as clean as possible, the machine has a collecting channel connected at one end to an ejector pipe. The collecting channel extends above the stripping wheel casings which are arranged in a row one beside the other and whose outlets extend obliquely upwards in the same direction towards the ejector pipe and open at intervals one after the other into a lower portion of the collecting channel. Besides, the lower portion of the collecting channel is at that side of each outlet of the wheel casing that faces the ejector pipe, provided with nozzles for injecting additional air into the collecting channel substantially in the direction of the ejector pipe end of the collecting channel.
