As FIG. 2 shows, the cross conveyor drum 5 »u ™ can Axis 6 of the picking attachment is pivotable, a further conveyor drum 7 can be connected upstream, which the picked Corn on the cob of the cross conveyor drum 5 supplies over its entire length. Those as right and left handed at the ends Conveyor screw-shaped transverse conveyor drum 5 guides the ones picked up by the picking devices 3 »4- and corn on the cob fed in via the further conveyor drum 7 to the center of the device and to one in the catchment area Entlieschtromniel arranged behind the cross conveyor drum 5 8th.

In the case of the harvesting machine according to FIG. 4-, which is designed as a maize harvesting device, it closes above the de-lapping drum 8, as also indicated in FIG. 2, a conveying device 9 for discharging the fleeces that have not been comminuted at.

The cross conveyor drum 5 * the Entlieschtrommel 8 and the Conveyor 9 are carried by a common frame, which in the embodiment of FIG uniaxial chassis rests with a drawbar 11 for connection to a not shown in the drawing Tractor is provided. The drawbar 11 can be pivoted in the horizontal plane in a known manner and be mounted lockable so that the corn harvester in the transport position behind the tractor and in the working position can run sideways next to the tractor track.

The Entlieschtrommel 8 is surrounded in its lower and rear circumferential area by a basket 12, the grid-like formed and can be arranged adjustable radially to the axis of the Entlieschtrommel. Instead of the basket at

030015/0017

a skinning drum is for the threshing drum of a combine harvester the sieve bottom is provided with an upstream grain attachment.

The Entlieschtrommel 8 is provided on its circumference with beater bars 13 or similar beating bodies, which during rotation the Entlieschtrommel in cooperation with the basket 12 the Peel lizards from the corn on the cob and pre-shred the corn on the cob. The pre-crushed pieces of corn on the cob fall through the basket 12 into a channel not shown in detail in the drawing and are conveyed by a conveyor a shredding device 14 arranged on the rear of the maize harvester, which is used as a knife-wheel chopper, Can be designed drum chopper or hammer mill.

On the basket 12 which partially surrounds the skinning drum 8 closes after the conveyor trough of the transverse conveyor drum 5 and optionally at a corresponding radial distance the further conveyor drum 7 on. Since the transverse conveyor drum 5 included in the harvesting machine represents the first link in the catchment area of such a machine, around the axis the cross conveyor drum 5, however, the picking attachment 2 is to be mounted so that it can be pivoted upwards, the conveyor trough 15 is the Cross conveyor drum 5 formed in two parts. As Fig. 2 in reproduces the individual, the machine-side part 16 ends of the conveyor trough I5 vertically below the cross conveyor drum shaft I7 in a horizontal plane and is supported by the on. Harvesting attachment 2 attached other part 18 of the conveyor trough 15 when coupled in the normal working position. Header partially overlapped from the front, so that the conveyor trough too when swiveled out relatively high. Header always remains closed. To when pivoting the header To prevent a gap between the two parts of the conveyor trough, for example, is the attachment-side part

030015/0017

of the conveyor trough 15 the machine-side part 16 from the front across under spring preload on the top of the machine-side part 16.

The desired pivoting position of the picking attachment 2 is brought about and held by hydraulic cylinders 19. The hydraulic cylinders 19 are supported with their cylinder housings on the device side and in.it their piston rods at a lower pivot point of the picking attachment 2.

In a modified version, the two-part design of the conveyor trough can also be made so that it is on the machine side and front part 16 or 18 of the conveyor trough 15 have the same radius of curvature, in the deepest Pivot position of the attachment 2 meet flush and that is formed when the attachment is pivoted up Gap is bridged by elastic connecting means, such as rubber bands, the connecting means with their long sides are attached to the adjacent edges of the conveyor trough parts 16 and 18, respectively.

As Fig. 3 shows, are at the laterally protruding end the cross conveyor drum 17 outside the on this side the Cross conveyor drum shaft 17 supporting bearing 24 two pulleys or gear wheels 22, 23 attached, via which a belt or chain drive coming from the harvesting machine 20 and one to the picking devices 3 »4 Belt or chain drive 21 is performed. By using the cross conveyor drum shaft 17 as a pivot axis for the attachment 2 thereby becomes a structurally simple drive for both the transverse conveyor drum and the picking devices won.
