The infeed rollers 19, 20 are to feed the harvested crop conveyed by the samuelvorricl:, device 1 up to its vicinity in a smooth V / eise into the inlet of the licking device 2 and their essentially cylindrical circumference is for this purpose with a few, preferably two or three , protruding axial strips 2k . The strips 2k can have a profile over their length, for example a sawtooth profile, which improves their grip on the crop. If it is desired to build the pulling rollers 19j 20 as close as possible to the front wall of the lapping device, the strips 2k can be arranged so as to be retractable so that there is practically no play between the rear wall of the pulling rollers and the front wall of the chopping housing. As a rule, however, this is not necessary and the strips 2k can be arranged firmly on the circumference of the rollers 19 »20. However, if the bars are to be retractable .k?, They can, for example, _o Being arranged resiliently pushed out or they may be connected with an extending within the feed rollers 19, 20 vertical eccentric shaft, whose eccentricity is chosen such, that the strips on the 2k V / alzen rear side are retracted (that is, on the housing front wall) within the roll circumference _o

At the front of the pair of intake rollers 19, 20 closes itself forward widening connecting channel 3, the bottom 25 'of which extends up to extends above a crossbar 26 which is just exposed from the circumferential prongs of the collecting device 1. The diverging side walls 27 of the connecting channel 3 are uniform with the parallel Side walls 28 of a hood built around the pick-up device 1, which further consists of an upper wall 29 extending over approximately a quarter circle around the collecting device.

The collecting device 1 has a transverse direction to the direction of travel horizontal main axis 18, which is driven in the manner already described, in such a way that the collecting device on its underside in the direction of travel, as indicated by an arrow B in FIG. The main axis 18 carries a flat, rectangular, rigid support member 30, which extends over the entire width of the collecting device and essentially in an axial plane of the main axis 18. On both of them Longitudinal edges of the support member 30 can be stationary, radially extending Tines arranged for collecting the harvested material lying on the ground

409883 / 03H

In the embodiment described, however, pivotable teeth 31 are attached to the longitudinal edges of the support member 30 , which are directed backwards and inwards from their pivot connection on the support member 30 with respect to the tancential sighting, and an end part 32 which is essentially bent radially outwards to have. The prongs 31, 32 can pivot between an inner position, in which their part 31 lies against the support member 30, and an outer position, in which their transition between the parts 31 and 32 lies against a limiting rod 33. The limiting rod 33 is between two disk-shaped end plates 5 ^ i 35 of the collecting device, which are fastened on the axis 18 at a small distance from the side walls 28 of the hood. Between the two. "- ündplatten 3 ^ and 35 thus extend two limiting rods 33 _f each delimiting a sink row 31» 32, and the two limiting rods 33 lie in an axial plane of the main axis 18, which is approximately perpendicular to the support member 30 containing axial jJplane extends.

the main axis 13 has a relatively high speed during operation, the tines 31 ₅ 32 are held against the limiting rods 33 by the centrifugal force, but if they hit an obstacle such as a stone, they can move backwards against the centrifugal force, soüass ec there is no risk of damage.

The upper v / and 29 of the arbor of the collecting device 1 ends at the front this device is slightly lower than the position of the main axis 1c and it carries a possibly height-adjustable, obliquely forward and inlet plate 56 bent upwards · ends at the underside of the hood the upper / and 29 in a possibly adjustable face plate 37 »the opposite a circle concentric to the main axis 18 directed somewhat inward and the rear edge of which lies approximately in a vertical plane extending transversely to the direction of travel and which extends through the entire tine ends of the collecting device 1 is tangent to the cylinder · Between the rear edge of the lens plate 37 and the front wall 38 of the shafts 13 and 17 and the housing enclosing the associated gear are there a relatively large opening through which the air flow generated by the collecting device 1 can escape.

A09883 / 03U

In operation, namely, the rotating support member jC of the collecting device generates an air flow with a relatively large air throughput in the hood 28, 29 and this air flow is favorable for the collection of the urn material, which is mostly in the form of swaths on the field. The harvested crop is thrown backwards through the hood 2o, 29 through the combined effect of the air flow and the tines 32 over the circumferential part of the pick-up device and the pull-in rollers are thrown through the 2 light plate 37 through the connecting channel 3 19 »20 brought in. The opening at the connection is essential for correct conveyance of the waste material so that the air flow can escape through this opening and thus the formation of an overpressure in the connecting channel 3 is prevented and, on the other hand, the transported material is given such kinetic energy that it perfectly covers its path in the seal of the 3 infeed rollers 19 »20.

Because the forage harvester in Aroeitsla.ge protrudes relatively far to the side of the tractor 7 and the combination in this position is too wide to drive over the road, the main frame beam k can be pivoted backwards by about 90 around the vertical hinge pin 5 up to the n; position indicated by dashed lines in FIG. However, in order to keep the ilauptges'telibalkon k in the working position, a rearwardly directed and upwardly open hook kO is provided on the trestle 6, in which the main frame beam k rests in the working position. The vertical hinge pin 5 at the end of the main frame h is unitary with a block which also has a horizontal hinge pin which is connected to the trestle 6. Ss is thus possible to Hauptg.estellbalken * f kl on padding to schu recessing upwardly and thereby free up the hook kO and then to pivot the llauptgestellbalken k backwards. In the working position, however, this pivoting is prevented by a locking bolt kZ (Fig. 3), which can be operated from the tractor 7 via a rope. When the alignment bolt k2 is withdrawn, the main frame beam h can be released from the hook kO by moving the three-point lifting device of the tractor 7 down.

By means of the rocking lever 8 on the other side of the main frame beam k , a height adjustment of this beam * t relative to the supporting beam 9 is possible, which on the one hand makes it easier to free the main frame beam k from the hooks and, on the other hand, ensures that the prongs are spaced sufficiently from the ground
