The invention relates to a portable forage harvester with two opposite, separately charged Cutting units.

The known arrangements of this type are mobile, but because of the wide expansive Devices and the spatial dimensions of the machine for use as a towed or self-propelled forage harvester not suitable.

The invention is based on the object of creating a forage harvester for precise cutting with which without increasing the structural dimensions, the performance is significantly increased.

According to the invention are for this purpose in a common housing on a common Shaft arranged two opposing, separately fed cutting units. The tools and the fan blades are attached to either side of a common writing wheel. The food that is to be cut is picked up from the ground by a common pick-up device, is by means of a dividing device (dividing tip, dividing disc or the like) divided into two strands of goods and cross-conveying devices, which, for example, consist of screw conveyors, conveyor belts, controlled drum tines etc. may exist, fed to the feed openings that are opposite to each other. That Cut material is discharged together and blown out via a common exhaust nozzle.

It helps to shorten the overall dimensions of a forage harvester constructed in this way essential when the common shaft of the two cutting units is parallel to the shaft of the pick-up device runs.

Since the forage harvester is a precision cutter, pressing devices are expediently Feed rollers or the like assigned to each feed device.

For all purposes where it seems appropriate to collect the goods separately after the cut or forward, according to the invention, the exhaust nozzle can be divided so that the Cuttings arising from two sides of the disc wheel are also conveyed further in separate directions can be.

This ensures that the crop flow is evenly distributed on both sides of the disc chopper housing is introduced and the cutting tools of the disc wheel the evenly allocated Cut well without significant impact stress and in cooperation with the Fan blades allow the continuous ejection of the chopped crop, so that with one

relatively small construction of the forage harvester a great performance can be achieved.

The drawing shows an exemplary embodiment, insofar as it is necessary for an understanding of the invention is shown in Figures I and II.

A b b. I shows a disc chopper in side view;

A b b. II illustrates the associated top view.

On the chassis or support frame, the disc chopper housing 2 is attached, in which the with Cutting tools and ejector blades occupied disk wheel 3 rotates in the direction of the arrow. The disk wheel shaft 4 is mounted in the bearings 6 fixedly attached to the support bracket 5. The crop will through the pick-up drum 7 from the ground or from the swath to the two lateral cross conveyors, z. B. feed screws 8, promoted, which the crop either directly or via a known, on both sides of the disc chopper housing 2 upstream feed or press device 9 (feed rollers) feed it to the two opposite cutting units. The exhaust nozzle 10, which is on Disk chopper housing 2 is seated, can be designed in two parts for better removal of chopped material be. For the continuous supply of the crop, the disc wheel chopper housing 2 is provided with a dividing point 11 (dividing disc or the like) assigned to the harvested crop on both sides of the transverse conveying devices, z. B. feed screws 8, feeds.
